Performance measurement in African semi-autonomous revenue authorities : The case of Kenya, South Africa and Tanzania. How can performance measures in African semi-autonomous revenue authorities (ARAs) be strategic, efficient and effective?Kariuki, Elizabeth Judy Nyawira. January 2012 (has links)
Semi-autonomous revenue authorities (ARAs) have been established all
over the world as a distinctive institutional model outside the traditional public
service aimed at enhancing tax administration, and thereby raising tax
revenues. In order to boost the robustness of their operations, substantial
expenditures have gone towards modernising ARAs. Expenditures have
been guided by medium-term corporate-wide plans, and the results
monitored, assessed and reported using performance measures.
Performance measurement has proved challenging for ARAs to implement
and sustain in practice. Some of the challenges evolve around weak
capacity, implementation costs, issues to do with quantification, competing
demands from a wide range of constituents, the inappropriate selection of
measures and a bias towards performance measures that focus on finances.
As a means for enhancing performance measurement, there are practices,
lessons and theoretical perspectives that can be discerned from the broadspectrum
of literature on performance measurement in the public sector and
ARAs from around the world. This thesis explores how performance measurement in African ARAs can be
more strategic, efficient and effective by ascertaining which key factors
shape its adoption. The research focuses on the in depth study of three
ARAs in Sub Saharan Africa, involving a combination of structured interviews
with internal and external stakeholders, the administration of a survey
instrument and review of ARA documents. The final chapters of the thesis
deploy fuzzy set logic techniques to identify and test the significance of
various causal conditions in the adoption of performance measurement in
ARAs, as a plausible answer to the research question.

Understanding The Implications of Internally and Externally Generated Revenue for Social Entrepreneurship: A critical AnalysisOkonkwo, Anthony January 2010 (has links)
Funding strategy has often been the determinant factor in the level of success for social entrepreneurships. The strategy could be a preference for internally generated revenue, externally generated revenue or a combination of the two. Interestingly, scarcity of resources has always been ‘a clog in the wheel’ of meaningful execution of projects irrespective of the funding model a social entrepreneur chooses. Through a review of existing literatures, this paper weighs the implications of choosing either externally generated revenue or internally generated revenue; specifically contextualizing the study to US. More so, it attempts to find out which of the two models would ensure optimum productivity, given that scarcity of resources would hamper the chances of effectively running the two models simultaneously. To arrive at a ‘plausible’ response, principles of resource valuation become vital in determining the costs and benefits associated with each model of funding. Consequently, the findings show that though both internally and externally generated revenue are sine qua non to an effective and efficient production of social values, internally generated revenue ensures better optimum production than externally generated revenue.

Le Agenzie pubbliche esecutive: il caso "Agenzia delle Entrate". Dal "Government" alla "Governance" del fenomeno tributario italiano / Executive Public Agencies: "The Italian Revenue Agency" Case. From "Government" to "Governance of Italian Fiscal PhenomenonRONDANINI, MARCO 27 March 2008 (has links)
Il contributo si propone – attraverso anche l'individuazione di punti di forza e di debolezza, di opportunità e di sfide (c.d. “SWOT Analysis”) – l'esame di una delle principali Agenzie pubbliche (esecutive) italiane, l' “Agenzia delle Entrate”: l'analisi dell'internazionale processo di c.d. “Agencification”, unitamente alla più sensibile dottrina versata nell'argomento, ne costituisce il presupposto teorico e comparato. La considerazione dell'adattamento al contesto italiano della modellistica internazionale (sub specie esecutiva: “structural disaggregation”; “reregulation”; “performance contracting”) e l'esame degli antecedenti storico-istituzionali e giuridici (interni) si palesano importanti linee di ricerca percorse. Lo specifico approfondimento dei profili storici, funzionali, strutturali e comparati – utilizzando lo strumentario euristico della contemporanea Scienza dell'Amministrazione – della recente esperienza istituzionale “Agenzia delle Entrate” mostra una sensibile, ma ancora parziale (specie sotto il profilo della c.d. “reregulation”), attuazione della ricordata modellistica agenziale esecutiva, ed al contempo evidenzia interessanti ipotesi di sviluppo istituzionale, già avvenute od in corso di manifestazione, per un passaggio – nella gestione del fenomeno tributario italiano – da un sistema a “Government” (ovvero verticistico e centralistico-ministeriale) ad un modello a “Governance” (cioè partecipato e qualificato dal principio di “sussidiarietà” istituzionale, verticale ed orizzontale), prima monolivello e stellare (la situazione attuale) e, quindi, multilivello e plurinodale (con l'avvento del c.d. “federalismo fiscale”). / The paper proposes - through the identification of strengths and weaknesses, opportunities and threats (so-called “SWOT Analysis”) – the examination of one of the major public (executive) Italian Agencies, the “Agenzia delle Entrate”: the analysis of international process so-called “Agencification”, together with the more sensitive doctrine well-versed in the argument, constitutes the theoretical and compared assumption. The adaptation to the Italian context of international modelling (sub executive specie: “structural disaggregation”, “reregulation” and “performance contracting”) and the exam of the historical-institutional and legal antecedents reveal important covered lines of search. The specific deepening of historical, functional, structural and comparative profiles - using the heuristic tools of contemporary “Science of Administration” – of the recent institutional experience “Agenzia delle Entrate” shows a sensitive, but still partial (especially in terms of s.c. “reregulation”), implementation of the mentioned agencial-executive modeling, and, at the same time, highlights interesting hypothesis of institutional development, already happened or in course of show, toward a transition – managing Italian fiscal phenomenon - from a “Government” system (top - down and centralist - ministerial) to a “Governance” model (participated and qualified by institutional, vertical and horizontal “subsidiarity”), first monolevel and stellar (current situation), therefore, multilevel and networked (with the advent of s.c. “fiscal federalism”).

Benchmarking the effectiveness of the Special Investigations Unit in the context of ongoing changes and the re-engineering of the South African Revenue Services (SARS)Scheepers, Daleen 12 1900 (has links)
Thesis (MBA)--Stellenbosch University, 2001. / Some digitised pages may appear illegible due to the condition of the original hard copy / ENGLISH ABSTRACT; SARS is the arm of Government tasked with collecting revenue for the State
and it is therefore contributing to the growth and development of South Africa.
The objective is to provide a world-class tax and customs service and
effectiveness therefore needs to be increase. It is the responsibility of the
SARS Special Investigations (SI) Unit to protect the South African economy
and society by being a leading law enforcement agency that focuses on
commercial related crimes.
This benchmarking study is an effort to identify best practices by comparing
the SARS SI Unit with nine other criminal or forensic services investigations
units in the Western Cape. Networking and partnerships between criminal
investigations units are very important in order to combat commercial crime
successfully. Half of the benchmarking participants are from the public sector
and the other half from the private sector. The study is done from a
management perspective and not from a technical legal perspective.
Benchmarking leads to better performance and a process of continuous
improvement. The SARS Siyakha re-engineering project is also currently
addressing more effective processes for the whole organisation, including SI.
One of the major problems of a criminal investigations unit is that it covers a
very wide and specialised field and cases become bigger and more complex,
because the criminals involved are using more sophisticated methods.
Commercial crime is also growing at a rapid rate and even extends to the core of corporate life and is threatening to corrupt the values of our country. In
criminal cases, the burden of proof is on the State and the standard of proof is
beyond reasonable doubt, which is a very high standard. The objective of the
criminal investigation is to obtain all relevant facts in dispute and to prove the
elements of fraud in such a manner as to ensure a successful prosecution.
Benchmarking represents a practical business application of the scientific
approach to problem solving. The benchmarking study was therefore done by
following a scientific approach, which encompasses a literature review,
personal interviews with each benchmarking participant, and the completion
of a questionnaire. During the interviews, critical success factors and problem
areas were discussed. From the author's viewpoint it was important to
provide a solid scientific foundation for the identification of best practices,
models and recommendations, instead of simply stating an opinion.
The key success factors and best practices identified were grouped into three
key areas: Inputs, professionalism and strategy; Process, procedures and
methodology; and Outputs and productivity. These three key areas were
chosen to ensure that a systems perspective was followed. The findings of the
study were also discussed, grouped and summarised in terms of the three key
areas. A multi-disciplined criminal investigations team model was also
developed as a result of the research and represents a combination between
what the private and public sectors are using. Final recommendations to
management and a conclusion complete the study. / AFRIKAANSE OPSOMMING: SARS is die arm van die Regering wie se taak dit is om inkomste vir die Staat
in te vorder en daardeur dra hulle ook by tot die groei en ontwikkeling van
Suid-Afrika. Die doelwit is om 'n wêreldklas diens te lewer om belasting en
doeane in te vorder en daarom moet doeltreffendheid verbeter word. Die
verantwoordelikheid van die SARS Spesiale Ondersoeke- (SO) afdeling is om
as 'n agent die Suid-Afrikaanse ekonomie en gemeenskap te beskerm deur 'n
toonaangewende wetstoepassingsagent te wees wat hom op kommersiële
misdaad toespits.
Hierdie maatstafstudie (benchmarking) is daarop gemik om beste praktyke te
identifiseer deur die SAID se SO-eenheid met nege ander kriminele of
forensiese ondersoekeenhede in die Wes-Kaap te vergelyk. Die daarstelling
van netwerke en vennootskappe tussen kriminele ondersoekeenhede is
geweldig belangrik in die stryd teen kommersiële misdaad. Die helfte van die
deelnemers aan die maatstafstudie is uit die privaat sektor en die ander helfte
uit die openbare sektor. Die studie is uit 'n bestuursoogpunt en nie vanuit 'n
regstegniese perspektief nie, gedoen. Maatstafstudies lei tot beter
produktiwiteit en 'n proses van deurlopende verbetering. Die SAID Siyakha
herontwerpprojek (re-engineering) is tans ook besig om die prosesse van die
hele organisasie, met inbegrip van dié van SO, te herontwerp.
Een van die grootste probleme wat 'n kriminele ondersoekeenheid ondervind
is dat dit 'n baie wye en gespesialiseerde veld dek en sake al hoe groter en moeiliker raak omdat die misdadigers wat betrokke is, meer gesofistikeerde
metodes gebruik. Kommersiële misdaad neem ook teen 'n geweldige tempo
toe en brei selfs uit na die hart van die korporatiewe sektor en word 'n
bedreiging vir die waardes van ons land. Die bewyslas in kriminele sake rus
op die Staat en die standaard van die bewyslas is bo redelike twyfel. Die doel
van kriminele ondersoeke is om al die relevante feite waaroor dit gaan te
openbaar en om die elemente van bedrog op so 'n manier te bewys en aan te
bied sodat 'n suksesvolle vervolging verseker kan word.
Maatstafstudies word gedoen deur middel van 'n wetenskaplike
probleemoplossingsbenadering en dit verteenwoordig 'n praktiese
besigheidstoepassing. Die maatstafstudie is daarom gedoen deur 'n getroue
navolging van 'n omvattende wetenskaplike benadering. Eerstens is 'n
teoretiese studie gedoen wat opgevolg is deur persoonlike onderhoude wat
die invul van 'n vraelys ingesluit het. Tydens die onderhoude is kritieke
suksesfaktore en probleemareas bespreek. Uit die skrywer se oogpunt was
dit deurentyd belangrik om 'n grondige wetenskaplike basis te hê vir die
identifisering van beste praktyke, modelle en aanbevelings, eerder as om net
'n persoonlike mening uit te spreek.
Die kritieke suksesfaktore asook die beste praktyke is gegroepeer in drie
hoofareas: Insette, professionele gedrag en strategie; Prosesse, prosedures
en metodologie; en Uitsette en produktiwiteit. Hierdie drie sleutelareas is
gekies om te verseker dat 'n stelselbenadering gevolg word. Die bevindings
van die studie is ook bespreek, gegroepeer en saamgevat onder die drie kernareas. Een van die resultate van die studie is dat 'n "multi-dissiplinêre
kriminele ondersoekspanmodel" ontwerp is wat verteenwoordigend is van 'n
gekombineerde toepassing tussen die privaat en openbare sektor. Die studie
word afgerond deur finale aanbevelings aan bestuur en 'n gevolgtrekking.

Federalismo fiscal e repartição do ICMS: o critério do valor adicionado / Fiscal federalism and ICMS revenue sharing: the value added criteriaCastilho, Fábio Roberto Corrêa 13 March 2014 (has links)
O trabalho concentra-se sobre o critério do valor adicionado fiscal na repartição do ICMS, com o objetivo de verificar sua adequação como mecanismo de provisão de recursos financeiros a Municípios, no contexto do federalismo fiscal brasileiro. Mediante análise teórica, de dados de distribuição e legislação referente à repartição e ao ICMS, identificamos que o valor adicionado fiscal é gerador de enormes desigualdades de tratamento entre Municípios de porte equivalente e de oscilações brutais de valores de transferência de um para outro ano, mas, sobretudo, que é juridicamente inadequado à multiplicidade de locais de ocorrência de fatos geradores e a heterogeneidade do imposto que pretende repartir. Não atinge, assim, o propósito de medir a adição de valor em um território, nem o de conferir aos Municípios receitas em montante similar ao potencial de arrecadação de um imposto sobre valor adicionado municipal depurado dos efeitos de imunidades, isenções, diferimentos e substituições tributárias, que justificou sua criação. A permanência da utilização do critério do valor adicionado por décadas é apontada no trabalho como resultante de acomodações e ajustes institucionais, característicos de dependência de trajetória (path dependence), que, desrespeitando os limites jurídicos de regulamentação, disfarçam a inadequação do critério e perpetuam as desigualdades e instabilidades dele advindas. Justifica-se, assim, que atenções sejam voltadas à análise de alternativas à repartição do ICMS por outros meios que não o VAF e o aperfeiçoamento de seus mecanismos de regulação, caso permaneça sendo utilizado. / The Added Value Criteria (VAF) is used in Brazil for purposes of ICMS (A State tax on circulation of goods, communication and interstate and intercity transportation services) revenue sharing to cities. The data on how the VAT based tax sharing occurs shows that VAT is a source of inequalities in resource distribution to cities of equivalent population and oscillations in the amounts received by a given city along the years. Moreover and as the central hypothesis of this thesis, VAF, as defined in Brazilian legislation, is not suitable to the complexity of situations and places of occurrence of ICMS taxable events nor to the effects of ICMS on prices, being, thus, unable to measure the value added in each city territory and to protect the revenue sharing from the effects of ICMS exemptions, constitutional immunities, deferrals and tax substitutions. Being so, the VAT regulations, do not recreate the potential of a municipal VAT, falling short in accomplishing the purposes it was created for. In spite of its defects, VAT remains in use decades after its creation as a result of accommodations and institutional adjustments that can be explained by a path dependence trajectory that was, and still, is able to disguise its chronic inadequacies and to perpetuate the inequalities and instabilities arising out of such distribution criteria. Our conclusions on VAF justify the study of other alternatives for the ICMS revenue sharing, as well as attempts to improve the quality of VAT regulations.

[en] YIELD MANAGEMENT IN RIO DE JANEIRO HOTELS: SURVEY AND ANALYSIS / [pt] YIELD MANAGEMENT NOS HOTÉIS DO RIO DE JANEIRO: LEVANTAMENTO E ANÁLISELUIZ GUSTAVO ALCURE DE MORAIS 10 March 2003 (has links)
[pt] Como conseqüência da desregulamentação da indústria aérea
americana nos anos 70, Yield Management YM foi criado como
uma ferramenta gerencial para maximizar os lucros e manter
as vantagens competitivas de empresas do setor.
Com o tempo, essa ferramenta passou a ser utilizada por
diversas empresas prestadoras de serviço, quando existe uma
demanda variável para uma capacidade fixa e elevado custo
de ociosidade, ajudando os gerentes a maximizar as receitas
das suas operações. Basicamente, YM é o processo de
alocação do tipo certo de capacidade, para cada tipo de
cliente, ao preço certo, para que se maximizem os lucros.
Pode-se ainda dizer que YM é uma forma sistemática de
realizar um tipo de preço discriminatório em função de
dados de demanda, de ocupação e dos custos marginais de
utilização do recurso (avião, hotel, ou outro sistema
prestador de serviço). Esta dissertação tem como objetivo
verificar como os maiores hotéis turísticos do Rio de
Janeiro se utilizam desta ferramenta em suas operações de
reservas e vendas. Para atingir tal objetivo, selecionou-se
uma amostra de onze hotéis na orla marítima. Entrevistas
foram realizadas com os respectivos gerentes responsáveis
pelo processo de reservas e/ou vendas, que responderam a um
sobre a atual aplicação dos elementos de YM dentro da
organização. Os resultados indicaram que o uso de YM é
ainda muito pouco difundido entre esses hotéis, sendo
reconhecido e de aplicação incipiente apenas em hotéis
de maior porte pertencentes a cadeias, sobretudo
internacionais. Alguns impedimentos indicados pelos
respondentes e inferidos de suas respostas são
comentados. / [en] As a consequence of the deregulation of the American
airline industry in the 70 s, Yield Management was created
as a managerial tool in order to maximize the profits and
to keep the competitive advantages of companies of the
sector. With time, this tool was adopted by other service
companies, where a flexible demand for a fixed capacity and
high under utilization costs exist, helping the
managers to maximize their operations revenues.
Yield Management (YM), or Revenue Management, is the
allocation process of the right type of capacity to each
type of customer at the proper price to maximize the sales
revenues of services, or of highly perishable goods. It can
still be said that YM is a systematic form to carry out a
type of discriminatory price to meet demand taking into
account occupation data and the marginal cost of
resource utilization (airplane, hotel, or another service
rendering system). The study presented in this thesis aimed
at verifying how the main tourist hotels of Rio de Janeiro
are taking advantages of this tool within their reservation
and sales processes. To accomplish this objective, a sample
of eleven hotels was selected amongst the fifteen more
important hotels of the main touristic area of
Rio de Janeiro City. Interviews were carried out with the
managers responsible for the reservation and, or sales,
departament, who answered a questionnaire about
the current application of YM elements within the
organization. The results have indicated that YM is still
very little spread out among these hotels, being recognized
and of incipient application, only in large hotel chains,
mainly, the international ones. Some obstacles pointed out
by the respondents and inferred from their responses are
commented.

Sustainable Revenue Generation System for Nonprofit Institutions of Higher EducationArcuri, Graig 01 January 2014 (has links)
Social and individual spending on higher education has outpaced social and individual economic growth, resulting in nonprofit institutions of higher education (NIHEs) growing increasingly dependent upon unsustainable governmental subsidies and tuition increases. The purpose of this study was to examine the interactions among components of the nonprofit university system, existing revenue generation methods, and sustainability of revenue generation, thereby generating a new sustainable revenue theory for nonprofit universities within the United States. This qualitative grounded theory study used a multiphase design incorporating data from the literature review, historical documents, and phone interviews from a theoretical sampling of 10 NIHEs. Participants were 20 faculty, 40 students, 40 administrative staff, and 20 members of the business community. Analysis included open, focused, axial, and theoretical coding. The study's findings theorize that a sustainable revenue generation system must continually include, and respond to, the multidirectional interactions of all system components as they change over time, including businesses. The result of the multidirectional connectivity between all of the system components was increased revenue for NIHEs and reduced student and government-funded tuition. Additionally, an organizational culture that is incongruent with change has been identified in NIHEs and must be mitigated. The findings of this study could positively affect NIHEs by providing a sustainable and adaptable system for improving revenue generation while increasing affordability and accessibility for students of these institutions, which, in turn, may produce positive social change.

The thesis used a deductive approach and the data (ticket prices) was collected during a time period of 53 days from Ryanair’s internet homepage. The theories used to analyze the data were price discrimination, price elasticity leverage, operating leverage and four different price strategies presented by Niklas L. Hallberg. The result shows that Ryanair uses second degree of price discrimination in all of the observed flights at the departure day. As for the rest, the result shows that there is a distinction between how Ryanair uses pricing as a strategy depending on what the destination is. The conclusion of the thesis is that Ryanair uses different price strategies depending on how popular the specific flight or destination is. The more popular the flight or destination is, the more dynamic the price is and the harder it is to predict the coming price. The pricing of the more popular flights could be, as presented by Piga and Bachis, a way of creating an uncertainty when it is the cheapest to buy airline tickets. Further the Study confirms Anjos, Cheng and Currie’s theory that the prices low-fare tickets are at a stable level until it remains about 20 days until departure, when the price increases until the departure date. This contradicts Anderson and Wilson’s theory that the ticket price goes in cycles where the price is at the highest level some days before departure before it starts to decrease.</p>

Air cargo revenue and capacity managementPopescu, Andreea 20 November 2006 (has links)
The traditional air cargo supply chain is composed by the shippers, the freight forwarders and the airlines. The freight forwarders secure capacity with airlines in order to accommodate shippers' demand. They bid for capacity six to twelve months before the actual departure date of the aircraft, and confirm the needed capacity a few days before departure.
We address the freight forwarders' problem of confirming needed capacity based on balancing the costs of ordering too much capacity versus ordering too little. We use a Markov decision process to model the problem. We show the value function is convex in the state variables for lead times of one and two periods. We present the structure of the optimal policy and show it is stationary. In addition we present solutions to the case with subcontracting options and order due dates.
We also address the airlines' revenue management problem with respect to its cargo capacity available for free sale (after honoring committed capacity to freight forwarders), in particular the problems of (1) accepting/rejecting incoming bookings based on bid prices, and of (2) estimating the show-up rate (ratio of bookings handed in at departure over bookings on hand) with impact on overbooking.
To address the lumpiness of demand, we split the cargo into two categories: small cargo, composed of mail and small packages, and large cargo, composed of the bulk of commercial cargo. The small cargo is approximated with the passenger arrival, and we propose a new algorithm to solve the traditional probabilistic nonlinear problem from the passenger side. The large cargo is solved using a dynamic program, which is decomposed
at the leg level using a fare-prorating scheme. The solution from our new approach is shown via simulation to be superior to two approaches currently used: the first come first serve, and the deterministic linear program.
The show-up rate is estimated using wavelets and we show that a discrete show-up rate is more suitable than the traditional Normal estimator used in practice. The new estimator results in considerable more potential revenue.
