Using systems thinking to create a viable student recruitment model : accommodating conflicting concerns in the student recruitment process.Mzimela, Leonard Mduduzi. January 2003 (has links)
The University of Natal has a Schools Liaison team that is responsible for undergraduate Students Recruitment. Recruitment activities are, however, not restricted to the Schools Liaison team. There are special programmes funded in part or wholly by corporate partners. These partnerships have placed additional demands on the recruitment function which is served by using special recruiters. Certain faculties have also chosen to make use of specialised recruiters in the form of Public Relations Officers. The presence of more than one group of individuals involved in Students Recruitment creates problems, more especially because the various groups of recruiters operate mainly within the same target market. The coming together of the conflicting and competing goals coupled with the parallel and independent recruitment drives of competing faculties, negatively affects the synergy that could be beneficial to the recruitment function. The focus of the study is on using systems thinking methodologies to engage stakeholders in a process that assists the University in creating a Student Recruitment Model that allows the various recruiters to pursue their various goals without harming the larger organisational goal and fragmenting the organization. The objective of this study is to use the Soft Systems Methodology as a tool aimed at developing a viable Student Recruitment model. This dissertation uses systems thinking methodologies to examine stakeho1der interests and concerns and attempts to bring all these together within a consolidated framework that should make up the viable Student Recruitment Model that serves the various interests within a single system. A number of lessons learnt during the process are highlighted and discussed in the last section of this study. The said lessons are considered valuable in the future as new demands arise and the organisation needs to modify its recruitment model. / Thesis (M.Com.)-University of Natal, Durban, 2003.

Improving the well-being of the poor through microfinance : evidence from the Small Enterprise Foundation in South AfricaKirsten, Maria Albertina 12 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2011. / ENGLISH ABSTRACT: Poverty in South Africa’s rural areas is complex and severe, especially among female-headed
households. The marginalisation of South Africa’s rural areas over a period of decades
resulted in an acute lack of economic opportunities, limited infrastructure and a serious
breakdown of social capital. Women living in rural areas are particularly poor in moneymetric
terms; they are often illiterate and therefore isolated from economic and social
opportunities; and many fall victim to violence in the household. They eke out a meagre
existence, based on small-scale agriculture, marginal self-employment or limited wage and
remittance income. While such income diversification, combined with the government’s
range of development interventions, helps to buffer them against risks such as illness, death
and disaster, rural poverty is not just a matter of income and assets. It is also rooted in other
disadvantages, such as exclusion, disempowerment and unequal power relations. These all
contribute to making poverty a multidimensional phenomenon.
The South African government has committed significant resources to poverty intervention
over the past 17 years. These interventions, which include social assistance grants, basic
municipal services and free water, electricity, schooling and health services, certainly have an
impact on the livelihoods of the rural poor, but they do not seem to bring a significant
improvement in the standard of living of the most vulnerable people in marginalised areas.
There is increasing recognition in the poverty literature that vulnerabilities – of income,
health, social exclusion and service delivery – are linked, and that support programmes
should focus not only on increasing the poor’s access to resources and assets but also on
empowering individuals to use these assets and make decisions.
This study investigates the potential of microfinance to address the overlapping
vulnerabilities experienced by women in South Africa’s rural areas. It suggests that
microfinance has the potential to generate positive shifts in selected indicators of
empowerment and well-being among participating women in rural areas. These claims are
tested by evaluating data gathered among clients of the Small Enterprise Foundation (SEF)
against a conceptual framework. The framework offers a stepwise progression away from
vulnerability: acquiring internal skills (empowerment), strengthening social capital,
accumulating assets and, eventually, transforming these assets into wealth. Existing datasets, gathered over a period of five years in rural Limpopo and representing both
a group that received microfinance from SEF and a control group, were examined. No
evidence could be found that the recipients of SEF’s microfinance experienced increased
empowerment, but the results did provide evidence that belonging to the group that received
microfinance increased the likelihood of experiencing livelihood security and well-being.
The findings show that microfinance can, even over the short term, make a difference in
people’s ability to smooth their consumption and, as such, provide them with more secure
livelihoods. The research also suggests that microfinance assists women in rural areas in
constructing and maintaining a portfolio of assets, thus improving well-being among the
recipients of microfinance.
The scope of the study was confined to measuring the effect of microfinance on selected
poverty indicators, and it did not attempt to prove that microfinance alleviates poverty. As
such, the research demonstrates that the government’s efforts to reduce rural poverty can be
complemented by micro-level interventions such as access to finance. / AFRIKAANSE OPSOMMING: Armoede in Suid-Afrika se landelike gebiede is kompleks en straf, veral vir huishoudings
met vroue aan die hoof. Landelike gebiede is vir dekades lank gemarginaliseer en dit het
gelei tot gebrekkige ekonomiese geleenthede, beperkte infrastruktuur en ‘n ineenstorting van
sosiale kapitaal. Vroue in Suid-Afrika se landelike gebiede is nie net arm in monetêre terme
nie, maar ook dikwels ongelettered, geïsoleerd van ekonomiese en sosiale geleenthede, en
dikwels die slagoffers van huishoudelike geweld. Hul huishoudings oorleef deur die skamele
bestaan wat hulle maak uit bestaansboerdery, gebrekkige besoldiging en trekarbeider lone.
Alhoewel die regering se wydverspreide ontwikkelingshulp daartoe bydra om arm mense te
help om risiko’s soos siekte, dood en natuurrampe te kan hanteer, gaan landelike armoede oor
veel meer as net inkomste en bates, en sluit dit ook ontmagtiging, uitsluiting en ongelyke
magsverdeling in. Al hierdie ontberinge maak armoede ‘n multidimensionele verskynsel.
Die Suid-Afrikaanse regering het oor die afgelope 17 jaar aansienlike bronne op armoede
verligting gespandeer. Die hulp, wat maatskaplike toelaes, basiese munisipale dienslewering,
gratis water, elektrisiteit, opvoeding en gesondheidsdienste insluit, het sonder twyfel die
oorlewing van die armes in landelike gebiede meer houdbaar gemaak, maar tog lyk dit nie of
die lewenskwaliteit van die mees kwesbare huishoudings in die gemarginaliseerde areas
verbeter het nie. Die armoede-literatuur dui daarop dat verskillende vorms van kwesbaarheid
– kwesbaarheid in terme van inkomste, gesondheid, sosiale uitsluiting en dienslewering – met
mekaar verband hou. Daarom is dit belangrik dat hulpverlening nie alleen vir die armes
toegang gee tot hulpbronne en bates nie, maar ook die individue bemagtig om die bronne te
gebruik en besluite te neem.
Hierdie studie ondersoek die potensiaal van mikrofinansiering om die verskeidenheid sosiale
kwesbaarhede wat vroue in Suid Afrika se landelike gebiede ervaar aan te spreek. Die studie
voer aan dat mikrofinansiering kan lei tot positiewe veranderinge in geselekteerde
bemagtigings- en welvaarts-indikatore onder deelnemende vroue. Data wat versamel is onder
die kliente van die Small Enterprise Foundation (SEF) word gebruik om hierdie aansprake te
evalueer. Die studie is gedoen teen die agtergrond van ‘n konseptuele model, wat voorhou dat
armoede en kwesbaarheid oorkom kan word as ‘n trapsgewyse program gevolg word – deur
eerstens kundigheid (bemagtiging) te verkry, daarna sosiale kapitaal te versterk, bates op te bou en uiteindelik die bates in rykdom te omskep beweeg die vroue, en hul huishoudings, al
verder weg van hulle aanvanklike kwesbaarheid.
Bestaande data, versamel oor ‘n tydperk van vyf jaar in die landelike gebiede van Limpopo is
geanaliseer. Die data verteenwoordig twee groepe – ‘n groep wat mikrofinansiering ontvang
het en ‘n kontrole groep. Geen empiriese bewyse kon gevind word dat die vroue wat
mikrofinansiering van SEF ontvang het, bemagtig is nie. Die resultate het wel daarop gedui
dat vroue wat mikrofinansiering ontvang na alle waarskynlikheid meer bestaans-sekerheid
het en dat hulle welvaart verbeter het. Die bevindinge dui daarop dat mikrofinansiering, selfs
oor die kort termyn, ‘n wesenlike verskil kan maak in die vermoë van kwesbare vroue om
hulle verbruik, oor tyd, beter te bestuur en sodoende bestaans-sekuriteit te verseker. Die
navorsing toon ook dat mikrofinansiering vroue in landelike gebiede kan help om ‘n
portefeulje van bates te skep en te handhaaf, wat bydra tot groter welvaart.
Hierdie studie het die impak van mikrofinansiering op geselekteerde armoede indikatore geevalueer,
en het nie gepoog om te bewys dat mikrofinansiering armoede verlig nie.
Sodoende dui die navorsing daarop dat die regering se pogings om armoede te verlig kan baat
vind by mikrovlakintervensies soos mikrofinansiering.

The performance of South African schools : implications for economic developmentTaylor, Stephen 12 1900 (has links)
Thesis (PhD (Economics)--University of Stellenbosch, 2010. / ENGLSIH ABSTRACT: At the time of South Africa‟s transition to democracy the school system was envisaged to be a powerful vehicle for nation-building and transformation. The chronic low performance of the South African school system has subsequently become the subject of widespread public concern. This thesis examines the distribution of cognitive achievement amongst South African children and the factors influencing it, especially socio-economic status, and asks what the implications of this are for future economic development. The methodologies employed are predominantly quantitative as various sources of data are examined in order to collect evidence pertaining to the question above.
Chapter 1 lays down a conceptual framework for understanding the role of schooling in economic development. The point is made that although education is often envisaged as a vehicle for development and mobility out of poverty, the home socio-economic status of children impacts significantly on their educational outcomes. Chapter 2 reviews recent and relevant literature to establish main currents of thinking regarding the influence of socio-economic status on educational outcomes. Chapter 3 follows this with an empirical examination of the influence of socio-economic status on reading achievement amongst South African children. The results indicate that the relationship between socio-economic status and educational achievement in South Africa is particularly strong by international standards. Furthermore, the historical divisions within the school system remain key to understanding continuing inequalities in educational outcomes. The socio-economic status of students is crucial in determining which part of the school system students enter; then for those entering the historically disadvantaged system the chances of achieving high quality educational outcomes are small, regardless of their home background.
The main priority in the latter part of chapter 3 and thereafter is the attempt to identify factors that improve cognitive achievement, given the socio-economic context of schools and their students. In chapter 4, this search is taken up by examining a rich collection of data regarding school and teacher practices in South African primary schools. In chapter 5 this is done by analysing trends in the ability of high schools to convert demonstrated grade 8 achievement into matric outcomes. An additional perspective is provided through a comparison of the performance of South Africa‟s independent and public schools in Chapter 6. The final chapter
summarises the results from these various approaches and highlights several key areas on which, it is recommended, attempts to improve South Africa‟s schools should focus. These include the management of school resources, teacher work ethic, time management and planning within schools, curriculum coverage, the accuracy of assessment and feedback to students, and parent commitment to education. Improving these areas within the large and struggling part of the South African school system will be decisive for the country‟s economic development. / AFRIKAANSE OPSOMMING: Ten tye van Suid-Afrika se demokratiese oorgang is die skoolstelsel as ʼn sterk instrument vir nasiebou en transformasie gesien. Die kroniese swak vertoning van die Suid-Afrikaanse skoolstelsel het sedertdien tot wye openbare besorgdheid gelei. Hierdie proefskrif ondersoek die verdeling van kognitiewe prestasie onder Suid-Afrikaanse kinders en die faktore wat dit beïnvloed, veral sosio-ekonomiese status, asook die implikasies daarvan vir toekomstige ekonomiese ontwikkeling. Die metodologie wat gebruik word, is hoofsaaklik kwantitatief, want verskeie databronne word ondersoek om getuienis in te win rakende bogenoemde vraagstuk.
Hoofstuk 1 stel ʼn konseptuele raamwerk daar om die rol van onderwys in ekonomiese ontwikkeling te verstaan. Die punt word gemaak dat, alhoewel onderwys dikwels as ʼn instrument vir ontwikkeling en uitstyging uit armoede gesien word, die sosio-ekonomiese status van kinders se huislike omgewing hulle onderwysuitkomste beduidend beïnvloed. Hoofstuk 2 bied ʼn oorsig van onlangse en relevante literatuur om die hoofstrome van denke oor die invloed van sosio-ekonomiese status op onderwysuitkomste aan te dui. Hoofstuk 3 volg dit op met „n empiriese ontleding van die invloed van sosio-ekonomiese status op leesvaardigheid onder Suid-Afrikaanse kinders. Die resultate dui daarop dat die verband tussen sosio-ekonomiese status en onderwysuitkomste volgens internasionale standaarde in Suid-Afrika besonder sterk is. Verder is die historiese verdelingslyne binne die skoolstelsel van sleutelbelang om voortgesette ongelykheid in onderwysuitkomste te verstaan. Die sosio-ekonomiese status van studente bepaal grootliks tot watter deel van die skoolstelsel kinders toegang kry. Vir daardie kinders wat in die histories-afgeskeepte deel van die stelsel beland, is die waarskynlikheid van hoë gehalte onderwys klein, ongeag hulle gesinsagtergrond.
Die klem in die laaste gedeelte van hoofstuk 3 en daarna val daarop om faktore te identifiseer wat kognitiewe uitkomste verbeter, gegewe die sosio-ekonomiese konteks van skole en studente. In hoofstuk 4 word hierdie speurtog voortgesit deur ʼn ryk verskeidenheid data rakende skole en onderwysers se praktyke in Suid-Afrikaanse laerskole te ondersoek. In hoofstuk 5 word dit gedoen deur ʼn analise van die vermoë van hoërskole om graad 8-vlak prestasie in graad matriekuitkomste te omskep. ʼn Vergelyking van die prestasie van Suid-Afrika se onafhanklike skole met openbare skole in hoofstuk 6 bied verdere perspektief hierop. Die finale hoofstuk som die bevindinge van hierdie verskillende benaderings op en belig sekere sleutelaspekte waarop
pogings om Suid-Afrika se skole te verbeter klem behoort te lê. Dit sluit in bestuur van skoolhulpbronne, onderwysers se werksetiek, tydsbestuur en beplanning binne skole, dekking van die kurrikulum, die akkuraatheid van assessering en terugvoer daaroor aan studente, en ouers se betrokkenheid by onderwys. Verbetering op hierdie gebiede binne die groot, sukkelende deel van die Suid-Afrikaanse skoolstelsel sal deurslaggewend wees vir die land se ekonomiese ontwikkeling.

A macroeconometric policy model of the South African economy based on weak rational expectations with an application to monetary policyBauknecht, Klaus Dieter January 2000 (has links)
Dissertation (PhD) -- University of Stellenbosch, 2000. / ENGLISH ABSTRACT: The Lucas critique states that if expectations are not explicitly dealt with,
conventional econometric models are inappropriate for policy analyses, as their
coefficients are not policy invariant. The inclusion of rational expectations in
·conventional model building has been the most common response to this critique.
The concept of rational expectations has received several interpretations. In
numerous studies, these expectations are associated with model consistent
expectations in the sense that expectations and model solutions are identical. To
derive a solution, these models require unique algorithms and assumptions
regarding their terminal state, in particular when forward-looking expectations are
present. An alternative that avoids these issues is the concept of weak rational
expectations, which emphasises that expectation errors should not be systematic.
Expectations are therefore formed on the basis of an underlying structure, but full
knowledge of the model is not essential. The accommodation of this type of
rational expectations is accomplished by means of an explicit specification of an
expectations equation consistent with the macro econometric model's broad
structure. The estimation of coefficients relating to expectations is achieved
through an Instrumental Variable approach.
In South Africa, monetary policy has been consistent and transparent in line with
the recommendations of the De Kock Commission. This allows the modelling of
the policy instrument of the South African Reserve Bank, i.e. the Bank rate, by
means of a policy reaction function. Given this transparency in monetary policy,
the accommodation of expectations of the Bank rate is essential in modelling the full impact of monetary policy and in avoiding the Lucas critique. This is
accomplished through weak rational expectations, based on the reaction function
of the Reserve Bank. The accommodation of expectations of a policy instrument
also allows the modelling of anticipated and unanticipated policies as alternative
assumptions regarding the expectations process can be made during simulations.
Conventional econometric models emphasise the demand side of the economy,
with equations focusing on private consumption, investment, exports and imports
and possibly changes in inventories. In this study, particular emphasis in the model
specification is also placed on the impact of monetary policy on government debt
and debt servicing costs. Other dimensions of the model include the modelling of
the money supply and balance of payments, short- and long-term interest rates,
domestic prices, the exchange rate, the wage rate and employment as well as
weakly rational expectations of inflation and the Bank rate.
The model has been specified and estimated by usmg concepts such as
cointegration and Error Correction modelling. Numerous tests, including the
assessment of the Root Mean Square Percentage Error, have been employed to test
the adequacy of the model. Similarly, tests are carried out to ensure weak rational
expectations.
Numerous simulations are carried out with the model and the results are compared
to relevant alternative studies. The simulation results show that the reduction of
inflation by means of only monetary policy could impose severe costs on the
economy in terms of real sector volatility. / AFRIKAANSE OPSOMMING: Die Lucas-kritiek beweer dat konvensionele ekonometriese modelle nie gebruik
kan word vir beleidsontleding nie, aangesien dit nie voorsiening maak vir die
verandering in verwagtings wanneer beleidsaanpassings gemaak word nie. Die
insluiting van rasionele verwagtinge in konvensionele ekonometriese modelle is
die mees algemene reaksie op die Lukas-kritiek.
Ten einde die praktiese insluiting van rasionele verwagtings III ekonometriese
modelbou te vergemaklik, word in hierdie studie gebruik gemaak van sogenaamde
"swak rasionele verwagtings", wat slegs vereis dat verwagtingsfoute me
sistematies moet wees nie. Die beraming van die koëffisiënte van die
verwagtingsveranderlikes word gedoen met behulp van die Instrumentele
Veranderlikes-benadering.
Monetêre beleid in Suid-Afrika was histories konsekwent en deursigtig in
ooreenstemming met die aanbevelings van die De Kock Kommissie. Die
beleidsinstrument van die Suid-Afrikaanse Reserwebank, naamlik die Bankkoers,
kan gevolglik gemodelleer word met behulp van 'n beleidsreaksie-funksie. Ten
einde die Lukas-kritiek te akkommodeer, moet verwagtings oor die Bankkoers
egter ingesluit word wanneer die volle impak van monetêre beleid gemodelleer
word. Dit word vermag met die insluiting van swak rasionele verwagtings,
gebaseer op die reaksie-funksie van die Reserwebank. Sodoende kan die impak
van verwagte en onverwagte beleidsaanpassings gesimuleer word. Konvensionele ekonometriese modelle beklemtoon die vraagkant van die
ekonomie, met vergelykings vir verbruik, investering, invoere, uitvoere en
moontlik die verandering in voorrade. In hierdie studie word daar ook klem
geplaas op die impak van monetêre beleid op staatskuld en die koste van
staatsskuld. Ander aspekte wat gemodelleer word, is die geldvoorraad en
betalingsbalans, korttermyn- en langtermynrentekoerse, binnelandse pryse, die
wisselkoers, loonkoerse en indiensneming, asook swak rasionele verwagtings van
inflasie en die Bankkkoers.
Die model is gespesifiseer en beraam met behulp van ko-integrasie en die gebruik
van lang-en korttermynvergelykings. Die gebruiklike toetse is uitgevoer om die
toereikendheid van die model te toets.
Verskeie simulasies is uitgevoer met die model en die resultate is vergelyk met
ander relevante studies. Die gevolgtrekking word gemaak dat die verlaging van
inflasie deur alleenlik gebruik te maak van monetêre beleid 'n swaar las op die
ekonomie kan lê in terme van volatiliteit in die reële sektor.

An institutional assessment of inflation targeting as a framework for monetary policyDu Plessis, Stan,1972- 12 1900 (has links)
Dissertation (PhD)--Stellenbosch University, 2003. / ENGLISH ABSTRACT: A number of themes run through this dissertation, the first of which is the importance of money
in facilitating decentralised decision making by lowering transaction costs and by contributing to
the definition and maintenance of property rights. A second (and more melancholy) theme is that
government control of money has often been poor, and systematically so since the War. This
leads to a third theme, the combined force of economic theory and central bank practice of the
last quarter of a century or so has led to clearer limits to the discretionary power of government
in the management of money. These limits are increasingly expressed as contingent rules
containing explicit targets for monetary policy, for example an inflation target.
The objective of this thesis is to evaluate inflation targeting both normatively and positively as a
framework for monetary policy. A set of criteria from the New Institutional Economics literature
is used to evaluate the extent to which inflation targeting captures the lessons from the three
themes mentioned above, in both normative and positive dimensions. The practical importance
of the thesis is in the application of this institutional evaluation to the inflation the targeting
regime of recent vintage in South Africa, which leads to a number of policy recommendations.
Part I consists of three chapters of which the first two are mainly abstract and concerned with
the theory of the New Institutional Economics. The third chapter has a historical character and
considers the history of and recent trends in monetary policy. These trends are consistent with
adopting an inflation target as a framework for monetary policy.
The second part of the thesis starts with a theoretical consideration of monetary policy rules in
chapter 4, and is followed by a discussion of one such rule, inflation targeting, in chapter 5. This
discussion starts with the theory of inflation targeting, but proceeds to details of actual inflation
targeting central banks, with special reference the South African Reserve Bank (SARB). The
history of anti-cyclical monetary in South Africa is also considered empirically to determine
whether inflation targeting would represent an important new direction on this issue.
Chapter 6 follows with a literature review of the empirical record of the first decade of inflation
targeting internationally. The seventh chapter is the core of the thesis and provides the
institutional evaluation of inflation targeting. This evaluation is applied to the present inflation
targeting regime in South Africa, and leads to recommended policy reforms. These policy reforms are mapped on a two-dimensional chart that indicates their priority and the expected
cost of the associated institutional reform. Additionally a new econometric methodology is used
in chapter 7 to gauge the contribution of monetary policy to the more stable economy of recent
years.
In part 3 the focus of the thesis turns to certain political economy considerations that arise from
the independence of the central banks (as is typical for inflation targeting central banks). Chapter
8 considers the issue of central bank independence and is followed by an application of
constitutional economics to inflation targeting in chapter 9. Whereas the bulk of the dissertation
is concerned with the positive evaluation of inflation targeting, chapter 9 attempts a normative
evaluation using the Pareto-Wicksell criterion. Both the positive and normative assessments in
this thesis support the case for inflation targeting as a framework for monetary policy, / AFRIKAANSE OPSOMMING: Die doel van hierdie proefskrif is 'n institusionele evaluering van inflasieteikening as raamwerk
vir monetêre beleid. Vir hierdie doel is 'n stel kriteria saamgestel uit die literatuur van die Nuwe
Institusionele Ekonomie met die oog op 'n positiewe en 'n normatiewe evaluering van
inflasieteikening as 'n raamwerk vir monetêre beleid. Die praktiese waarde van die tesis lê in die
stel institusionele hervormings wat voorgestel word om die stelsel van inflasieteikening in Suid-
Afrika meer doeltreffend en normatief meer gewens te maak.
Etlike temas loop deur die proefskrif, maar veral drie verdien vermelding in die opsomming,
naamlik: eerstens, die belangrikheid van die monetêre stelsel om gedesentraliseerde besluitneming
te vergemaklik en as bydraende faktor in die vestiging van eiendomsreg. Tweedens, hoewel
moderne owerhede tipies 'n monopolie op die plaaslike geldeenheid bestuur, het die monetêre
bestuur in die moderne tydgewrig (veral sdert WOII) veel te wense oorgelaat. Hierdie
wanbestuur was boonop telkens sistematies. Derdens, beide teoretiese ontwikkelings en die
praktyk van sentrale bankwese het die afgelope kwarteeu aanleiding gegee tot 'n terugrol van die
regering se rol in monetêre beleid en die toenemende gebruik van sistematiese beleidsreëls as
raamwerk vir monetêre beleid.
Die eerste deel van die proefskrif beskou die teorie van die Nuwe Institusionele Ekonomie in
hoofstukke 1 en 2. Die derde hoofstuk is histories van aard en beskou die geskiedenis van
moderne monetêre beleid en die tendense wat daaruit afgelei kan word.
Afdeling twee fokus meer nougeset op inflasieteikens en begin met die teorie van beleidsreëls in
hoofstuk 4. Die vyfde hoofstuk volg met 'n interpretasie van inflasieteikens as een van die
sogenaamde terugvoerreëls vir monetêre beleid wat sedert die laat sewentigerjare ontwikkel is en
sedertdien gewild geword het. 'n Toenemende aantal ontwikkelde- en ontwikkelende-lande het
gedurende die afgelope dekade (en langer) inflasieteikens as raamwerk vir monetêre beleid
aangeneem. Hoofstuk ses evalueer die empiriese rekord van hierdie kort geskiedenis. Die
sewende hoofstuk is die kern van die tesis en bevat die institusionele evaluering van die
inflasieteikens aan die hand van die kriteria saamgestel in hoofstuk 1, met spesifieke toepassing
op Suid-Afrika. 'n Nuwe ekonometriese tegniek word ook in hoofstuk 7 gebruik om die bydrae
van monetêre beleid tot die meer stabiele ekonome van onlangse tydgewrig te kwantifiseer. Die netelige institusionele kwessie van onafhanklik sentrale banke word rue 111 hoofstuk 7
bespreek rue, maar staan oor tot deel drie van die proefskrif waar die politieke-ekonomie van
inflasietekens bespreek word. Hoofstuk 8 handel dan oor onafhanklike sentrale banke, met
toepassing op die SARB, terwyl hoofstuk 9 'n toepassing is van die konstiutionele ekonomie op
inflasieteikening. Hoofstukke 8 en 9 bied derhalwe verdere positiewe evaluering van die
instrument-onafhanklike SARB onder inflasieteikens, asook 'n normatiewe evaluering van
inflasieteikens aan die hand van die Pareto-Wicks ell kriteria wat uit hoofstuk 2 spruit. Beide die
normatiewe en positiewe evaluerings ondersteun die saak ten gunste van inflasieteikens as
raamwerk vir monetêre beleid.

The introduction of new technology in a mature industry : an evolutionary analysis of the South African textile industryJafta, Rachel Catharina Cornelia 12 1900 (has links)
Dissertation (PhD)--Stellenbosch University, 2003. / ENGLISH ABSTRACT: At the beginning of the 1990s, the South African textile industry faced many
challenges, including the dismantling of protective barriers, requiring firms to
adapt to increased foreign competition in the local and global markets. Many
opted for investment in new technology. This study set out to analyse the
behaviour of South African textile firms in the process of introducing new
technology in pursuit of competitiveness.
The analysis was conducted following the evolutionary approach in economics
(discussedin Chapter 2). This approach incorporates time, pays attention to the
deliberate actions of firms to shape their environment, as well as persistent
diversity amongst firms.
This study asked two broad questions. First, what were the major trends in
textiles regarding technology, demand-side factors, the trade regime, etc.?
(Chapter3). Chapter 3 sets the scene for the rest of the study in that it
illustrates how the competitive environment of textile firms has changed and
argues that the aggregate picture is often not a true reflection of the dynamics
of the industry, thus paving the way for micro-level analysis of firms and
institutions. Secondly, what were the subsequent responsesby textile firms and
institutions to these changes?This question is investigated for the global textile
industry (Chapter 3), the South African, Italian and Mauritian textile industries
(Chapters 4 and 5), and for specific firms in the South African textile industry
(Chapters 6 and 7).
Institutions play an important role in shaping the development of industries, just
as firms in an industry may influence institutions. The role of institutions in the
South African textile industry is considered in Chapter 5, which serves as
background to Chapter 6, where we enquire about the significance of these
institutions from the firms' perspective. The central focus of Chapter 6,
however, is on the processof acquisition and implementation of new technology
in South African textile firms. The implications of this process for other
strategies, organisational processes, competencies, and routines are also analysed. Basedon the outcome of the firm-level analysis, three categories of
firms are distinguished, namely leading firms, moderate adapters, and laggards.
Using the characteristics of the firms in each category, we select three firms to
pursue further in case studies. Chapter 7 presents the results of these case
studies. Although the main focus of our study is on the implementation of new
technology, we want to illustrate in this chapter how the successof this process
critically depends on factors such as an appropriate organisational structure, the
competencies of management and labour, as well as the institutions in the
industry. We further highlight the important role that individuals, such as
entrepreneurs, play in shaping the paths of firms, their relationships with
institutions, suppliers, and customers, and even the structure of the industry.
We conclude that investing in new technology is a necessary but not sufficient
strategy for successful rejuvenation of firms in a mature industry.
Complementary changes, such as in organisational structure, use of human
resources, and supply-chain relations, are of crucial importance, too (Chapter
8). / AFRIKAANSE OPSOMMING: Aan die begin van die 1990s het die Suid-Afrikaanse tekstielbedryf menige
uitdagings (soos die aftakeling van beskermingsmaatreëls) in die gesig gestaar,
wat hulle gedwing het om meer doeltreffend in die plaaslike en globale markte
te word. Hierdie studie ontleed die gedrag van ondernemings in die
tekstielbedryf in die proses van verkryging en implementering van nuwe
tegnologie ten einde mededingingendheid te bevorder.
Die studie volg die evolusionêre benadering, wat tyd inbou en aandag skenk aan
doelbewuste aksies deur maatskappye om hulle omgewing te beïnvloed, asook
volgehoue diversiteit tussen maatskappye (Hoofstuk 2).
Die studie het twee breë vrae gestel. Eerstens, is daar gekyk na die belangrikste
tendense t.O.V. tegnologiese veranderinge, vraagkantfaktore, handelsregulasies,
ensovoorts, in die tekstielbedryf (Hoofstuk 3). Hoofstuk 3 skets die struktuur vir
die res van die studie deur die veranderinge in die omgewing waarbinne
tekstielmaatskappye meeding uit te lig, maar ook deur aan te toon dat die
globale prentjie nie altyd 'n ware refleksie van die dinamiek van 'n nywerheid is
nie, omdat soveel diversiteit daardeur verbloem kan word. Hierdie argument is
dus ten gunste van verdere mikrovlak analise van ondernemings en instellings.
Tweedens word gevra watter reaksies op hierdie veranderinge daar van
ondernemings en instellings se kant af was. Hierdie vraag word ondersoek vir die
globale tekstielbedryf (Hoofstuk 3), die Suid-Afrikaanse en Italiaanse
tekstielbedrywe, asook die bedryf in Mauritius (Hoofstuk 4 en 5). Verder word
die vraag vir spesifieke Suid-Afrikaanse ondernemings in Hoofstukke 6 en 7
bestudeer.
Instellings speel 'n belangrike rol in die ontwikkeling van nywerhede, net soos
ondernemings in nywerhede ook instellings kan beïnvloed. Die rol van instellings
in die Suid-Afrikaanse tekstielbedryf word in Hoofstuk 5 behandel, deels as
agtergrond vir Hoofstuk 6 waar die belangrikheid van instellings uit die
ondernemings se oogpunt van naderby beskou word. Die hooffokus van Hoofstuk
6 is egter die verkryging en implementering van nuwe tegnologie in Suid-Afrikaanse tekstielmaatskappye. Die implikasies wat hierdie proses vir ander
strategieë, organisatoriese prosesse, vaardighede en roetines van die
ondernemings inhou, word ook bestudeer. Voortvloeiend uit die
ondernemingsvlakanalise, word drie kategorieë van ondernemings onderskei,
naamlik leiers, middelmatige aanpassers en sloerders. Op grond van die
kenmerke van die ondernemings in elkeen van die kategorieë is drie
maatskappye vir verdere ontleding in gevallestudies gekies (Hoofstuk 7).
Alhoewel die hooffokus van die studie die implementering van nuwe tegnologie
is, illustreer ons ook in Hoofstuk 7 dat die proses sterk beïnvloed word deur
faktore soos die organisatoriese struktuur, die vaardighede van die bestuur en
werkers, sowel as die instellings in die industrie. Ons beklemtoon verder die
belangrike rol wat individue, soos entrepreneurs, speel t.O.V. die
ontwikkelingstrajek van ondernemings, sowel as die verwantskappe wat
ondernemings met verskaffers, instellings en klante opbou. Aksies deur individue
beïnvloed in die finale instansie ook die struktuur van die industrie.
Ons gevolgtrekking is dat investering in nuwe tegnologie 'n noodsaaklike maar
nie voldoende strategie vir die suksesvolle vernuwing van ondernemings in 'n
volwasse nywerheid is nie. Komplementêre veranderinge, byvoorbeeld in die
organisatoriese struktuur, die benutting van arbeid, en verhoudings in die
verskaffingsnetwerk, is ook van kernbelang.

The regulation of deposit-taking financial institutions : a comparative analysis of the United Kingdom, Germany and South AfricaJordaan, Michael 03 1900 (has links)
Thesis (PhD)--Stellenbosch University, 1997. / ENGLISH ABSTRACT: Standard financial literature contains various explanations for the unique role of
deposit-taking intermediaries in an economy. None of these reasons adequately
explains the extensive degree of banking regulation evident in practice.
The nature of a deposit, which guarantees capital repayment independent of bank
performance, uniquely incentivises banks to be exposed to financial risks. In the
absence of appropriate regulation, banks may be tempted to assume an
unacceptably high level of risk that could ultimately result in bank failure. Thus, the
regulation of banking risks is justified in terms of the public interest theory whereby
banking regulation seeks to avoid the market imperfections arising from informational
asymmetries and "domino" externalities associated with bank failure. Accordingly, the
rationale of banking regulation lies in the protection of consumers and in preserving
the stability of the financial system. Direct monetary controls, on the other hand,
impact adversely on the risk-management activities of banks.
The framework utilised to analyse and compare banking regulation consists of three
broad categories namely: preventative regulation, protective regulation and monetary
requirements.
Preventative or prudential regulation is aimed at managing the levels of risks
assumed by banks. This form of regulation relates to entry requirements; limitations
on certain business activities; the disclosure of risk-related information; the adequacy
of capital resources; portfolio restrictions on risk assets; and the sufficiency of
liquidity.
Protective regulation is concerned with the immediate protection of depositors and
maintenance of overall financial stability once a bank has failed. lt consists of crisis
management measures and deposit insurance schemes.
Direct, and hence inappropriate, monetary requirements are variations in reserve
asset requirements, as well as interest rate and credit controls.
The banking systems of South Africa, the United Kingdom and Germany were
chosen to perform a comparative analysis of financial regulation.
The London financial markets are mature and a large variety of banks are regulated
in a flexible manner by the Bank of England. By contrast, the strictly regulated
German banks dominate their domestic financial system. South Africa is a hybrid of
the former systems with a modern banking industry operating in well developed
financial markets and supervised according to advanced risk-management
considerations.
The analysis of preventative and protective regulation in all three financial systems
indicates that banking regulation is indeed concerned with the regulation of banking risks. The efforts of the Bank for International Settlements to harmonise regulation
across domestic financial systems has contributed significantly to improved
regulatory techniques for the management of these risks. None of the three systems
make use of direct monetary requirements which suggest awareness of the costs
associated with such regulation.
A number of recommendations are made to improve financial regulation in South
Africa: extension of regulatory coverage to include other types of financial
intermediaries who also engage in risky activities; further relaxation of exchange
control regulations which restrict the foreign exchange risk management; the
adoption of a formal deposit protection scheme; increased consolidated supervision
by a single regulatory authority with executive powers; further deregulatory measures
in instances where regulations are not appropriate from a risk-management
perspective; and re-regulation to the extent that the risk-management activities can
be regulated more efficiently. / AFRIKAANSE OPSOMMING: Die finansiele literatuur bevat verskeie verklarings vir die unieke rol wat
depositonemende instellings in 'n ekonomie vervul. Geeneen van die redes verskaf
'n bevredigende verklaring vir die wye omvang van bankregulasies in die praktyk nie.
Die aard van 'n deposita is sodanig dat die terugbetaling van die kapitaalsom deur 'n
bank gewaarborg word, onafhanklik van die winsprestasie van die bank. Gevolglik
het banke die unieke eienskap om hulself aan finansiele risikos bloat te stel. Sander
gepaste regulering sou banke moontlik daartoe geneigd wees om oormatige hoe
risikovlakke na te streef wat tot bankmislukking kan lei. Die regulering van
bankrisikos vind dus bestaansreg in die teorie van openbare belang, d.w.s. dat
regulering die potensiele markmislukkings, wat voortspruit uit asimmetriese inligting
en "domino" eksternaliteite, kan voorkom. Die rasionaal van bankregulering is die
beskerming van verbruikers, asook die handhawing van 'n stabiele finansiele stelsel.
Direkte monetere beheermaatreels, daarenteen, het 'n ongunstige uitwerking op die
bestuur van risikos deur banke.
Die raamwerk waarbinne bankregulering ontleed en vergelyk word, bestaan uit drie
kategoriee, naamlik voorkomende regulering, beskermende regulering en monetere
vereistes.
Voorkomende regulering is daarop gemik om die risikos waaraan banke blootgestel
is te bestuur. Sodanige regulering verwys na toelatingsvereistes, beperkings op
sekere sake-aktiwiteite, die openbaarmaking van risiko-verwante inligting, die
toereikendheid van kapitaalhulpbronne, beperkings ten opsigte van baterisikos en
voldoende likiditeit.
Beskermende regulering is gemoeid met die beskerming van deposante en bestaan
uit krisisbeheermaatreels en depositoversekeringskemas.
Direkte (en gevolglik ontoepaslike) monetere vereistes bestaan uit veranderlike
reserwebatevereistes, asook rentekoers- en kredietbeheermaatreels.
Die bankstelsels van Suid Afrika, die Verenigde Koningkryk en Duitsland is gekies vir
'n vergelykende analise van finansiele regulering.
Die finansiele markte in Londen is hoogs ontwikkeld en 'n groat verskeidenheid en
aantal banke word op 'n pragmatiese wyse deur die Bank of England gereguleer. In
direkte teenstelling daarmee word die Duitse banke, wat hul binnelandse finansiele
markte domineer, onderwerp aan 'n streng formele toesighoudingstelsel. Die SuidAfrikaanse
finansiele stelsel bevat elemente van beide bogenoemde stelsels, by
wyse van 'n moderne banksektor, wat funksioneer in goed ontwikkelde finansiele
markte en gereguleer word ooreenkomstig gevorderde risikobestuursbeginsels.
Die analise van voorkomende en beskermende regulering in die drie finansiele
stelsels, bevestig dat bankregulering inderdaad afgestem is op die regulering van finansiele risikos. Die pogings van die Bank van lnternasiona~e Vereffeninge om die
regulasies in finansiele stelsels internasionaal met mekaar in orreenstemming te
bring het wesenlik hiertoe bygedra. Die vermyding van direkte monetere vereistes
dui verder daarop dat toesighoudende owerhede bewus is van die nadele van
sodanige regulering.
'n Aantal aanbevelings word gemaak, naamlik: meer omvattende regulering ten
einde ander finansiele instellings wat ook finansiele risikos bestuur, te dek; verdere
verslappings van valutabeheermaatreels wat tans die bestuur van wisselkoersrisiko
beperk; die totstandkoming van 'n formele depositoversekeringstelsel; 'n groter mate
van gekonsolideerde toesighouding; verdere deregulering in gevalle waar regulasies
vanuit 'n risikobestuursoogpunt nie wenslik is nie; en her-regulering in die mate
waartoe die risikobestuurspraktyke meer effektief gereguleer kan word.

Modelling the ecological-economic impacts of restoring natural capital, with a special focus on water and agriculture, at eight sites in South AfricaCrookes, Douglas John 12 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: The restoration of natural capital has ecological, hydrological and economic benefits. Are these benefits greater than the costs of restoration when compared across a range of dissimilar sites? This study examines the impact of restoration at eight case study sites distributed throughout South Africa. The benefits of restoration include improved grazing values and crop yields, improvements in water yield and quality, soil carbon improvements, wild products, lumber, fuelwood and electricity. The impact of restoration on all forms of natural capital (i.e. cultivated, replenishable, renewable and non-renewable) is therefore quantified. The costs of restoration include depreciation on capital expenditure, labour costs, equipment and bond refinancing costs. The literature review done during this study presents three frameworks. The first framework classifies social science using the classification scheme of Burrell and Morgan. It shows that system dynamics modelling and neoclassical economics share the same epistemological and ontological characteristics, both of these fall within the naturalistic paradigm, which also characterises most of scientific research. System dynamics modelling and neoclassical economics, however, digress in the Flood and Jackson classification scheme, which is the second framework for classifying social science. Neoclassical economics is characterised by a small number of elements and few interactions between the elements. Systems dynamics modelling, on the other hand, is characterised by a large number of elements and many interactions between the elements. The nature-freedom ground motive is subject to a number of criticisms, including the fact that it introduces dualistic thinking into the analysis, as well as that it does not adequately address normative or moral issues. The framework of Dooyeweerd, the third framework, is presented as a means of transcending the nature-freedom ground motive. Although the nature-freedom ground motive is largely utilised in this study, the analysis does transcend the traditional economic approach in a number of areas. These include, for example, a focus on transdisciplinary methods, disequilibria, adopting a case study approach, and empirical estimation instead of theoretical models. The restoration case studies in this study are examples of individual complex systems. Eight system dynamics models are developed to model interactions between the economic, ecological and hydrological components of each of the case studies. The eight system dynamics models are then used to inform a risk analysis process that culminates in a portfolio mapping exercise. This portfolio mapping exercise is then used to identify the characteristics and features of the different case study sites based on the risk profile of each sites. This study is the first known application of system dynamics, risk analysis and portfolio mapping to an environmental restoration project. This framework could potentially be used by policymakers confronted with budgetary constraints to select and prioritise between competing restoration projects. / AFRIKAANSE OPSOMMING: Die restorasie van natuurlike kapitaal het ekologiese, hidrologiese en ekonomiese voordele. Maar is hierdie voordele groter as die kostes verbonde aan restorasie wanneer dit oor verskeie ongelyksoortige terreine vergelyk word? Hierdie studie bestudeer die impak van restorasie op agt verskillende studie terreine versprei regoor Suid-Afrika. Die voordele van restorasie sluit die volgende in: beter weiding waardes en oes opbrengste, verbeterde water lewering en water kwaliteit, verbetering van grondkoolstof, wilde produkte, hout, brandstofhout en elektrisiteit. Die impak van restorasie op alle vorme van natuurlike kapitaal (gekultiveerd, aanvulbaar, hernubaar en nie-hernubaar) is daarom gekwantifiseer. Die kostes van restorasie sluit in ‘n vermindering in kapitaal uitgawes, arbeidskoste, toerusting en verband herfinansieringskoste. Die literatuurstudie hou drie raamwerke voor. Die eerste raamwerk klassifiseer sosiale wetenskappe volgens die Burrel en Morgan klassifikasie skema. Dit wys daarop dat dinamiese stelsel modellering en neoklassieke ekonomie dieselfde epistemologiese en ontologiese eienskappe deel; beide val binne die naturalistiese paradigma, wat dan ook meeste wetenskaplike navorsing tipeer. Stelseldinamiese modellering en neoklassieke ekonomie wyk egter af na die Flood and Jackson klassifikasie skema, wat die tweede raamwerk is waarvolgens sosiale wetenskappe geklassifiseer word. Neoklassieke ekonomie word gekenmerk aan 'n klein aantal elemente en 'n beperkte hoeveelheid interaksie. Stelseldinamiese modellering het egter 'n groot aantal elemente met veel meer interaksies tussen hierdie elemente. Die natuur-vryheid grondmotief is onderworpe aan 'n aantal punte van kritiek, insluitende die feit dat dit dualistiese denke in analise inbring. Verder spreek dit ook nie voldoende die normatiewe of morele kwessies aan nie. Die raamwerk van Dooyeweerd, wat dan die derde raamwerk is, word voorgestel as 'n wyse waarop die natuur-vryheid grond-motief getransendeer kan word. Alhoewel die natuur-vryheid grondmotief grootliks gebruik word in hierdie studie, transendeer die analise die tradisionele ekonomiese benadering op 'n aantal gebiede. Hierdie gebiede sluit die volgende in: 'n fokus op transdissiplinere metodes, onewewigtigheid, 'n gevallestudie benadering, en empiriese skatting in plaas van teoretiese modelle. Die restorasie gevallestudies wat in hierdie studie gebruik word is voorbeelde van individuele komplekse sisteme. Agt dinamiese stelsel modelle word ontwikkel om die interaksies tussen ekonomiese, ekologiese en hidrologiese komponente in elke gevallestudie te modelleer. Hierdie agt stelseldinamiese modelle word dan gebruik in 'n risiko analise proses wat uitloop op 'n portefeulje plot oefening. Hierdie portefeulje plot oefening word dan gebruik om eienskappe en kenmerke van verskeie gevallestudie terreine te identifiseer gebaseer op die risiko profiel van elke terrein. Hierdie studie is die eerste bekende toepassing van dinamiese stesels, risiko analise en portefeulje plot tot 'n omgewingsrestorasie projek. Hierdie raamwerk kan potensieël gebruik word deur beleidskrywers wat met begrotings beperkinge gekonfronteer word om tussen restorasie projekte te kies en om hulle te prioritiriseer.

Using household surveys for deriving labour market, poverty and inequality trends in South AfricaYu, Kwan Cheung Derek 12 1900 (has links)
Thesis (PhD)--Stellenbosch University, 2012. / ENGLISH ABSTRACT: In order to evaluate the extent to which South Africa achieve the objectives of poverty and
inequality reduction as well as job creation, up-to-date and reliable data are required. Since
the transition, various survey data have been commonly used for these analyses, namely
Census, Community Survey (CS) 2007, Income and Expenditure Survey (IES), October
Household Survey (OHS), Labour Force Survey (LFS), Quarterly Labour Force Survey
(QLFS), General Household Survey (GHS), Project for Statistics on Living Standards and
Development (PSLSD), National Income Dynamics Study (NIDS) and All Media Products
Survey (AMPS).
However, these datasets are not fully comparable, due to differences in the sampling design,
sample size, questionnaire structure, methodology to derive labour market status, as well as
the way the income and expenditure information was collected. Hence, this dissertation
begins by analysing these issues in each survey in Chapter 2. With regard to the income and
expenditure information, it was collected differently in the surveys: the recall method was
used in all surveys except IES 2005/2006, the only survey that adopted the diary method;
respondents were asked to report the actual amount in some surveys but only asked to declare
the relevant interval in others; for the former approach, respondents could either declare the
single estimate amount or amounts for sub-categories that were then aggregated; for interval
data, various methods can be used to determine the amount in each interval. Thus, Chapter 3
begins by discussing the merits and drawbacks of these approaches, as well as how they
would affect the reliability and comparability of income and expenditure variables across the
surveys.
In some surveys (e.g., the two censuses and CS 2007), quite high proportions of households
incorrectly reported zero income or expenditure or did not specify their income or
expenditure. Poverty and inequality estimates could be influenced by either including or
excluding these households from the analyses. Hence, various approaches to deal with these
households are examined in Chapter 3. As the surveys typically under-captured income or
expenditure when compared with the national accounts income, the validity of the resultant
poverty and inequality estimates might be affected. Hence, arguments for and against
adjusting the survey means in line with the national accounts mean (e.g. by shifting the survey
distribution rightwards) are discussed. As the survey data are, strictly speaking, crosssectional
and not designed for time-series labour market, poverty and inequality analyses, it is sometimes argued that the data should be re-weighted to be consistent with demographic and
geographic numbers presented by the Actuarial Society of South Africa (ASSA) and Census
data. This cross entropy re-weighting approach is discussed in Chapter 3. Finally, the chapter
examines the labour market status derivation methodology in all OHSs, LFSs and QLFSs in
greater detail, and investigates how the changes across the surveys could possibly affect the
comparability of labour market estimates throughout the years.
The dissertation then examines the labour market trends since the transition by using the
OHS, LFS and QLFS data, and it is found that both the labour force and employment numbers
increased in general since the transition, but the latter increase was not rapid enough to absorb
the expanding labour force. In addition, the number of narrow unemployed doubled between
1994 and 2009, and the narrow unemployment rate showed an upward trend and peaked at
just above 30% in 2003. It decreased between 2004 and 2007, before rising again in 2008-
2009 due to the impact of global recession. Application of the cross entropy approach does
not substantially affect labour market trends, suggesting that the trends (including the abrupt
increase in labour market estimates during the changeover from OHS to LFS) were either real
or took place due to the improvement of the questionnaire to capture the labour market status
of the respondents better. Furthermore, the application of the LFS 2000b-LFS 2007b
methodology on the earlier surveys reduced the extent of the abrupt increase of the number of
broad unemployed and broad unemployment rates during the changeover between OHS and
LFS. Finally, the use of the QLFS methodology (which required minor revisions) on the LFSs
greatly reduced the extent of the abrupt decrease of unemployment aggregates between LFS
2007b and QLFS 2008Q1, thereby improving the comparability of these aggregates across the
surveys.
In Chapter 5 poverty and inequality concepts are reviewed, followed by a detailed explanation
of the sequential regression multiple imputation (SRMI) technique to deal with households
with zero or missing income or expenditure, as well as the derivation of real income,
expenditure and consumption variables in each survey. Poverty and inequality trends since the
transition are examined in Chapter 6. With regard to poverty, with the exception of AMPS,
the poverty trends were very similar across the surveys, that is, poverty increased since the
transition, before a downward trend took place since 2000. As far as inequality is concerned,
both the levels and trends in the Gini coefficients differed a lot amongst the surveys, as the
estimates were very stable in the AMPSs, showed an upward trend in surveys like IESs and GHSs, but first increased until 2000 before a downward trend took place in others (e.g., the two censuses and CS 2007). The levels of inequality also differed when comparing the
surveys. The abovementioned poverty and inequality estimates and trends could in part be
affected by the various issues discussed in Chapter 3, thus there is a need for careful analysis.
The impact of the number and width of intervals in which income or expenditure data are
recorded on poverty and inequality estimates and trends are dealt with in greater detail in
Chapter 6 by applying various intervals on the three IESs and NIDS 2008. It is found that the
number and width of intervals only had some impact on these estimates and trends in some
surveys. The effect of adjusting the survey means in line with the national accounts mean is
also investigated. Finally, the application of the cross entropy re-weighting technique did not
have any significant impact on the poverty and inequality estimates and trends. / AFRIKAANSE OPSOMMING: Data wat op datum en betroubaar is word vereis om te kan evalueer in watter mate Suid-
Afrika sy doelwitte rakende die vermindering van armoede en ongelykheid en die skepping
van werkgeleenthede bereik. Sedert die politieke oorgang word verskeie opnamedatastelle
gewoonlik vir sulke ontledings gebruik, byvoorbeeld Sensusse, die Gemeenskapsopname van
2007, Inkomste- en Bestedingsopnames, Oktober-huishoudingsopnames,
Arbeidsmagopnames, Kwartaallikse Arbeidsmagopnames, Algemene-Huishoudingsopnames,
die Nasionale-Inkomste-Dinamika-Studie en die Alle-Media-en-Produkte-opnames.
Weens verskille in steekproef-ontwerp, struktuur van die vraelyste, metodologie om
arbeidsmarkstatus te klassifiseer, asook maniere waarop inligting oor inkomste en besteding
ingewin is, is hierdie datastelle egter nie ten volle vergelykbaar nie, Gevolglik begin hierdie
proefskrif in Hoofstuk 2 om elk van hierdie kwessies in elke opname te ontleed. Inkomste- en
bestedingsinligting is in die opnames verskillend ingewin: In die meeste opnames is
respondente gevra om aan te dui hoeveel hulle in die verlede bestee of verdien het, maar in
die Inkomste- en Bestedingsopname van 2005/2006 is die dagboekmetode gebruik;
respondente is in party opnames gevra om die presiese bedrag te vermeld, terwyl hulle in
ander opnames die betrokke inkomste- of bestedingsinterval moes aandui; vir eersgenoemde
is hulle gevra om òf die enkelbedrag te verklaar, òf hulle moes ‘n aantal sub-komponente
onderskei; vir intervaldata kan verskillende metodes gebruik word om skattings van die
inkomste in elke interval te maak. Dus begin Hoofstuk 3 met ‘n oorsig van die voor- en
nadele van die verskillende benaderings en ‘n bespreking van hoe dit die betroubaarheid en
vergelykbaarheid van inkomste- en bestedingsveranderlikes oor die opnames beïnvloed.
In party opnames (bv. die twee sensusse en die Gemeenskapsopname van 2007) dui heelwat
huishoudings verkeerdelik aan dat hulle geen inkomste verdien of uitgawes aangaan nie, of
hulle spesifiseer nie hoeveel hulle verdien of bestee nie. Ramings van armoede en
ongelykheid kan geraak word deur sulke respondent in te sluit of deur hulle uit te laat in die
ontledings. Gevolglik word verskeie benaderings in Hoofstuk 3 bespreek om hiermee om te
gaan. Omdat opnames vergeleke met die nasionale rekeninge tipies inkomste of besteding
onderskat, mag dit die geldigheid van daaruitvoortspruitende armoede- en
ongelykheidsramings raak. Gevolglik word argumente vir en teen die aanpsssing van die
opname-data om dit in ooreenstemming te bring met die nasionale rekeninge (d.w.s. deur die
verdeling na regs te verskuif) bespreek. Ten slotte, omdat die opnamedata streng gesproke kruissnitdata is en nie ontwerp is vir tydreekse van die arbeidsmag, armoede en ongelykheid
nie, word soms aangevoer dat die gewigte van die data herweeg moet word om in
ooreenstemming te wees met demografiese en geografiese data soos verkry van die Aktuariële
Vereniging van Suid-Afrika en sensusdata. Hierdie kruisentropie herwegingsmetode word in
Hoofstuk 3 bespreek. Ten slotte ondersoek die laaste hoofstuk die metodologie vir die
bepaling van arbeidsmarkstatus in all die OHS, LFS en QLFS opnames in groter
besonderhede, en ook hoe die veranderings oor die verskillende opname-reekse heen dalk die
vergelykbaarheid van arbeidsmarkramings deur die jare kan beïnvloed.
Die proefskrif ontleed daarna arbeidsmarktendense sedert die politieke oorgang met gebruik
van die Oktober-huishoudingsoponames, Arbeidsmagopnames en Kwartaallikse
Arbeidsmagopnames. Beide die arbeidsmag en indiensneming het sedert die transisie
toegeneem, maar die toename in indiensneming was onvoldoende om die uitbreiding van die
arbeidsmag te absorbeer. Verder het die getal eng-gedefinieerde werkloses tussen 1994 en
2009 verdubbel, en die eng werkloosheidskoers het ‘n toename getoon en in 2003 ‘n toppunt
van 30% bereik. Dit het daarna tussen 2004 en 2007 gedaal voordat dit weer in 2008-2009
gestyg het weens die wêreldreseessie. Die toepassing van die kruisentropie-benadering het
arbeidsmarktendense nie noemenswaardig beïnvloed nie, wat daarop dui dat hierdie tendense
(insluitende die skielike toename in arbeidsmagramings in die oorgang van die Oktoberhuishoudingsopname-
data na die Arbeidsmarkopname-data) werklik was, of anders
plaasgevind het weens veranderings in die opnamevraelyste om respondente se
arbeidsmarkstatus beter te probeer bepaal. Verder het die toepassing van die LFS2000b tot
LFS 2007B metodologie op die vroeëre opnames die abrupte verlaging in die oorgang tussen
die OHS en LFS in die getal breed-gedefineerde werkloses en breë werkloosheidkoerse
verminder. Ten slotte het die gebruik van die QLFS-metodologie op die LFS (wat kleiner
hersienings benodig het) die abrupte verlaging tussen LFS2007b en QLFS2008Q1 aansienlik
verminder, en dus die vergelykbaarheid van hierdie groothede oor die opnames heen verbeter.
In Hoofstuk 5 word eers ‘n oorsig van armoede- en ongelykheidsbegrippe gegee, waarma die
sekwensiële-regressie-veelvoudige-imputasie-tegniek in besonderhede bespreek word.
Hierdie tegniek word veral gebruik vir gevalle waar huishoudings aandui dat hulle inkomste
of besteding nul is, of waar hulle nie antwoord nie. Daar is ook ‘n bespreking van die
bepaling van reële inkomste, besteding of verbruiksveranderlikes in elke opname. Armoedeen
ongeleykheidstendense word in Hoofstul 6 bespreek. Rakende armoede is daar, met
uitsondering van die Alle-Media-en-Produkte-opname, eenstemmigheid dat dit sedert die
politieke oorgang eers gestyg het voor dit sedert 2000 begin daal het. Sover dit ongelykheid
aanbetref verskil neigings in die Gini-koëffissiënt baie tussen die opnames, want die ramings
is stabiel oor die periode vir die Alle-Media-en-Produkte-opname, styg vir die Inkomste- en
Bestedingsopname en die Algemene-Huishoudingsopnames, en styg tot 2000 voordat dit
afneem in ander opnames (bv. die twee sensusse en die Gemeenskapsopname van 2007).
Vlakke van ongelykheid verskil ook tussen die opnames. Deels kan die genoemde tendense in
armoede- en ongelykheid dalk toegeskryf word aan die kwessies wat in Hoofstuk 3 bespreek
is.
Die effek van die getal en wydte van die intervalle waarin inkomste- en bestedingsdata
ingewin word op ramings van armoede en ongelykheid word in meer besonderheid in
Hoofstuk 6 bespreek. Deur die toepassing van verskillende intervalle op data van die drie
Inkomste- en Bestedingsopnames en die Nasionale-Inkomste-Dinamika-studie word bevind
dat die getal en wydte van intervalle ‘n beperkte effek op hierdie ramings en tendense het.
Verder word gekyk na die effek van die aanpssing van die opname-data om dit in
ooreenstemming met die nasionale rekeninge te bring. Ten slotte word getoon dat die gebruik
van die kruisentropie-metode nie enige beduidende uitwerking op armoede- en
ongeleykheidsramings en -tendense het nie.
