Evaluation of the implementation of an HIV/AIDS workplace policy for farm workers : a case study of Country Mushrooms

Monnakgotla, Nakedi Margaret 02 1900 (has links)
Farm workers in South Africa have limited access to health care and health-related information. In this qualitative study, the implementation of a workplace HIV/AIDS policy was evaluated using data gathered through interviews and observation. It was found that, although the farm workers were knowledgeable about HIV and AIDS, this knowledge was insufficient. It was found that the lives of farm workers are deeply affected by HIV and AIDS. It is also suggested that the agricultural sector is not yet able to deal effectively with HIV and AIDS and that, in this regard, urgent planning is needed in respect of HIV and AIDS policies and interventions / Social Work / M.A. (Social Behaviour Studies in HIV/AIDS)

The social needs of farm workers in the Koup : suggesttions for employee assitance programmes (EAPS) from a social work perspective

Botes, Jacolise 11 1900 (has links)
Farm workers are viewed as a neglected segment in the South African society. This qualitative research study focused on exploring and describing the social needs of farm workers in the Central Koup from the perspectives of samples comprising of farm workers and farm owners and/or managers. The aim was to contribute in finding solutions to address the identified needs through employee assistance programmes (EAPs) as one of the areas that an occupational social worker focuses on. The qualitative data was collected through focus group discussions and semi-structured interviews, and the findings were verified with literature. Tesch’s framework for data analysis (in Creswell, 2003) was employed, and data verification was conducted through Guba’s model (in Krefting, 1991:214-222). The findings indicated that the social needs of farm workers could be addressed through typical EAP-related focus areas such as working- and interpersonal relationships, substance abuse, spiritual well-being, recreation, financial management, conflict management, child care and parenting skills, trauma counselling, and practical assistance regarding transport, housing and accessibility of resources. This research endeavour resulted in recommendations regarding the use of EAPs to address the social needs of farm workers. / M. Soc. Sc.

'n Kritiese evaluering van die arbeidsregtelike posisie van plaaswerkers in Suid-Afrika

Calitz, Karin Beatrix 11 1900 (has links)
Summaries in English and Afrikkans / The aim of this thesis is to investigate the labour law position of South African farm workers. For three and a half centuries farm workers constituted the most neglected group in the South African labour force. Consequently, an understanding of their present position can only be obtained by investigating their labour history. As in other parts of the world, farm workers in South Africa held a subordinate position to agricultural employers. Discrimination against black persons added to the inferior socio-economic and political position of South African farm workers. White farmers occupied a strong political position during most of the time under investigation, which enabled them to institute and apply discriminatory legislation and informal methods to overcome labour shortages. The freedom of movement of black people and their access to land were restricted to create a cheap immobile labour force. During the 20th century farmers prevented the inclusion of farm workers in labour legislation by exercising their political influence. Pressure by industrial trade unions and encouragement by the International Labour Organisation (ILO) resulted in the adoption of the Agricultural Labour Act which made labour legislation applicable to farm workers, but precluded them from striking and made allowance for longer working hours than for industrial workers. The new political dispensation facilitated the inclusion of farm workers in general labour legislation without any discriminatory exceptions and land reform legislation now protects farm workers against arbitrary evictions. A bill of rights furthermore guarantees the rights of farm workers which were previously violated. It would superficially seem that farm workers' problems are something of the past. Farm workers, however, remain handicapped in exercising their new rights by historical factors and circumstances peculiar to the agricultural sector. Legal comparison with Ontario and California confirms that legislation alone is insufficient to empower farm workers. It is recommended that the government amend existing legislation to accommodate the special needs of farm workers and that relevant ILO conventions, especially Convention 141 of 1975, be ratified to aid the development of unions for farm workers. This will contribute to the empowerment of and social justice for farm workers. / Die doel van hierdie tesis is om die arbeidsregtelike posisie van Suid-Afrikaanse plaaswerkers te ondersoek. Plaaswerkers was vir drie en 'n half eeue die mees afgeskeepte groep in die Suid-Afrikaanse werksmag. Om die huidige posisie van plaaswerkers te begryp is dus slegs moontlik deur 'n bestudering van die regsgeskiedenis van plaaswerkers. Soos in ander werelddele beklee plaaswerkers in Suid-Afrika 'n minderwaardige posisie teenoor landbouwerkgewers. Diskriminasie teenoor swartpersonehet bygedra tot die sosio-ekonomiese en polities minderwaardige posisie van Suid-Afrikaanse plaaswerkers. Blanke boere het gedurende die grootste deel van die tydperk onder bespreking 'n sterk politiese posisie beklee wat hulle in staat gestel het om diskriminerende wetgewing en informele metodes aan te wend om arbeidstekorte te bowe te kom. Swart persone se bewegingsvryheid en toegang tot grond is beperk om 'n goedkoop immobiele werksmag te vorm. Gedurende die 20ste eeu het boere se sterk politiese posisie hulle in staat gestel om te verhoed dat plaaswerkers by arbeidswetgewing ingesluit word. Druk deur industriele vakbonde en aanmoediging deur die Intemasionale Arbeidsorganisasie (IAO) het gelei tot die Wet op Landbou-arbeid waardeur arbeidswetgewing op plaaswerkers van toepassing gemaak is, maar wat plaaswerkers verbied het om te staak en wat voorsiening gemaak het vir langer werkure as vir industriele werkers. 'n Nuwe politieke bedeling het gelei tot die insluiting van plaaswerkers in algemene arbeidswetgewing sonder enige diskriminerende uitsonderings en grondhervormingswetgewing beskerm plaaswerkers nou teen arbitrere uitsettings. 'n Handves van menseregte waarborg verder die regte van plaaswerkers wat voorheen misken is. Oenskynlik is die probleme van plaaswerkers nou iets van die verlede. Plaaswerkers word egter steeds in die uitoefening van hulle nuwe regte gestrem deur historiese faktore en die eiesoortige omstandighede van die landbousektor. Regsvergelyking met Kalifomie en Ontario het aangetoon <lat wetgewing alleen nie voldoende is om plaaswerkers te bemagtig nie. Daar word aanbeveel dat die regering bestaande wetgewing wysig om voorsiening te maak vir die spesiale behoeftes van plaaswerkers en dat relevante IA0 konvensies, veral Konvensie 141 van 197 5 geratifiseer word om die ontwikkeling van vakbonde vir plaaswerkers te bevorder. Dit sal bydra tot die bemagtiging van en tot sosiale geregtigheid vir plaaswerkers / Law / LL.D.

The forgotten ones: A case study of the obstacles that prevent meaningful participation in democratic governance of farm women in the greater Stellenbosch Area, Ceres & Rawsonville

Saal, Querida Shahida 03 1900 (has links)
Thesis (MA (Political Science))--University of Stellenbosch, 2010. / ENGLISH ABSTRACT: This research examines the extent of participatory democracy, as outlined in government policy, with particular relevance to the experiences of women living on farms in the Greater Stellenbosch Area, Ceres and Rawsonville. The study is based on the notion that effective and meaningful political participation in South Africa has happened at the exclusion of many of its poor and marginalised citizens, in particular poor women living on farms. The research hypothesis holds that various factors relating to the socioeconomic conditions and political orientations of farm women contribute to their low levels of participation in democratic governance. The research question therefore is: what are the obstacles that prevent women living on farms in the Greater Stellenbosch Area, Ceres and Rawsonville from effective and meaningful participation in participatory democracy? In answering the research question, mixed methods of data gathering were employed. Qualitative methods were used, with data-gathering techniques that included modified participant observation, non-scheduled structured interviews, and a focus group discussion. As relatively little is known of the experiences of farm women, these techniques were all geared towards better informing the researcher about relevant questions for the quantitative component of the research in the form of a survey. From the findings, the hypothesis that farm women do not participate in a meaningful process of participation was confirmed. The main findings in terms of the obstacles that prevent meaningful participation can be discussed in three categories. Firstly, the research indicates that farm women feel that since their opinions are not considered by politicians there is no reason for them to participate in governance. Secondly, because of a lack of capacity and resources critical for optimal participation, the women are also disempowered to not participate in politics. Finally, farm women are tired of empty promises and the abuse of power by corrupt officials. Hence they have become very cynical of processes that are supposed to be participatory, but in effect are not authentic at all. In conclusion, although participation is advanced on the basis of the principle of enhancing democracy, the lived realities of farm women cannot be ignored. Therefore, it is vital that participation in politics be seen from a holistic perspective, relying on both democratic principles and the socioeconomic development of farm women. Through political iii participation, farm women must be empowered to become not only democratic citizens, as envisioned by theorists of participatory democracy, but also capacitated people who live a dignified life. / AFRIKAANSE OPSOMMING: Hierdie navorsingsprojek bestudeer die omvang van deelnemende demokrasie, soos uiteengesit in regeringsbeleid, spesifiek met betrekking tot die ervaringe van vroue wat op plase in die Groter Stellenbosch Area, Ceres en Rawsonville woon. Die studie is gebaseer op die argument dat effektiewe en betekenisvolle politieke deelname in Suid Afrika die meerderheid arm en gemarginaliseerde burgers, en spesifiek arm vroue op plase, uitsluit. Die navorsingshipotese is dat verskeie faktore wat verband hou met die sosioekonomiese omstandighede en politieke oriëntasies van plaasvroue bydra tot hulle lae vlakke van politieke deelname. Vervolgens is die navorsingsvraag: Wat is die faktore wat vroue op plase in die Groter Stellenbosch Area, Ceres en Rawsonville daarvan weerhou om effektief en betekenisvol deel te neem aan die politiek? Gemengde metodes van data-insameling is gebruik om die navorsingsvraag te beantwoord. Kwalitatiewe data-insamelingstegnieke sluit in aangepaste deelnemende observasie, niegeskeduleerde gestruktureerde onderhoude en ʼn fokusgroepbespreking. Aangesien relatief min inligting oor plaasvroue bestaan, is die doel met die tegnieke om die navorser beter in te lig om vrae vir die kwantitatiewe komponent, ʼn opname, te skep. Deur die bevindinge is die hipotese dat plaasvroue nie gereeld aan effektiewe en betekenisvolle deelnemende prosesse deelneem nie bevestig. Wat die faktore wat deelname beïnvloed betref, is daar drie verskillende temas. Eerstens dui die navorsing daarop dat plaasvroue voel dat aangesien hulle opinies nie deur politici in ag geneem word nie, daar geen rede vir hulle is om aan die politiek deel te neem nie. Tweedens is plaasvroue as gevolg van ‘n gebrek aan die kapasiteit en hulpbronne noodsaaklik vir optimale deelname ook geneig om minder aan die politiek deel te neem. Laastens is die vroue moeg van leë beloftes en die misbruik van mag deur korrupte amptenare. Gevolglik is hul nou meer sinies, spesifiek oor prosesse wat veronderstel is om deelnemend te wees maar in werklikheid glad nie is nie. Ten slotte, alhoewel deelname aan die politiek bevorder word op grond van die beginsel dat dit demokrasie verbeter, kan die lewensomstandighede van plaasvroue nie geïgnoreer word nie. Hiervolgens is dit noodsaaklik dat deelname in die politiek vanuit ‘n holistiese oogpunt beskou word, gegrond op beide demokratiese beginsels en die sosio-ekonomiese ontwikkeling van plaasvroue. Deur politieke deelname moet plaasvroue bemagtig word om nie net demokratiese burgers te word nie, maar ook gekapasiteerde mense wat n waardige lewe lei.

Skills and quality production in the South African wine industry

Brown-Luthango, Mercy 03 1900 (has links)
Thesis (DPhil (Sociology and Social Anthropology))--Stellenbosch University, 2007. / There is a general consensus amongst industry experts that in order for the South African wine industry to sustain the success it has enjoyed thus far in export markets like the United Kingdom, the Netherlands and Sweden and to become even more internationally competitive, its has to improve the quality of its wine and move into higher price categories of the wine market. Skills’ training has been highlighted as a significant component of a strategy to improve the quality of South African wine and its competitiveness in world markets. The aim of this study was to find out how the South African wine industry is adapting to new vineyard practices necessary for quality production at farm level, especially as far as training of vineyard workers is concerned. Four theoretical perspectives are discussed in relation to the restructuring of the world agro-food industry, the question of quality and the issue of training as it relates the production of quality wine. These theoretical perspectives are regulation theory, global commodity chain analysis, actor-network theory and the ergonomics perspective on the skills needed for the production of quality wine. The focus of the study was on different kinds of producers, i.e. co-operative cellars, private cellars and estates. The research covered two of the main wine-producing areas, namely Paarl and the Robertson area. At each farm, interviews were conducted with the farm owner, farm manager or viticulturist as well as a number of workers. Interviews were also conducted with prominent wine makers, skills trainers and facilitators and other industry experts. This was done to gain a better understanding of the South African wine industry as well as the major issues and debates as far as quality production and skills training are concerned. The study found that although there has been a general upgrading of skills in relation to new vineyard practices for quality production, workers at the co-operatives and estates studied do not yet receive the kind of in-depth knowledge which the theory argues is necessary for the production of quality wine. The private cellars invest much more time and resources in the training of their workforce. As far as the private cellars and estates are concerned there is a correlation between the quality of wine and training. The private cellars sell more than 50% of their wine in the premium, super-premium, ultra-premium and icon categories of the international wine market. The estates sell 70% and more of their wine in the basic category. The co-operatives on the other hand do not confirm the theory. In the absence of formal training, they manage to produce wine that competes well on an inter and intra-regional level. The evidence suggests that in a country like South Africa, in the context of a legacy of low education and literacy levels amongst workers, repeated demonstration and strict supervision can compensate to a certain degree for a lack of in-depth knowledge and discretion amongst workers.

Evaluating the performance of farmworker participation schemes in the Western Cape Province

Ndlozi, Collen Vusi 04 1900 (has links)
Thesis (MScAgric)--Stellenbosch University, 2005. / ENGLISH ABSTRACT: It is generally acknowledged that South African commercial agriculture will have to be restructured to integrate the previously disadvantaged communities in the agricultural economy of the country. This is so because of the prevailing disparities between agriculture amongst the black societies and the traditional "white" commercial agriculture. After the inception of the ANC governance in 1994, affirmative action measures viz inequalities and inequitable access to resources and markets became necessary to remove these imbalances. However, it is not seen as a quick fix; it will take decades to eradicate the imbalances created during the period of apartheid rule. A farmworker equity-sharing scheme (FWESS) was first introduced at the Whitehall farm in the Grabouw area of the Western Cape in 1992. The South African Department of Land Affairs adopted this strategy in the face of land reform as one of the major Land Redistribution for Agricultural Development programmes to provide basic support to the farmworkers in order to enable them to participate in the financial stakes of the commercial farming in South Africa. The main research objective of this study was to evaluate the performance of FWESSs and assess the contribution of the programme to the improvement of the living standards of the previously disadvantaged individuals, viz farmworkers. This was achieved through a survey, which included five FWESSs administered by the Cape Town regional office of the Department of Land Affairs (DLA). Interviews were conducted amongst the ordinary farmworkers, members of the board of worker trustees and the original owners. Among other things, the motivations, characteristics of governance, socio-economic factors and financial performance of the schemes were evaluated. It is evident from the investigation that the original owners are in the forefront in the initiation of the equity-sharing schemes on their farms. Job security was shown as the most important motivation by some farmworkers for their participation in equity-sharing schemes, while other shareholders (original owners) indicated that the initial capital injection in the business and the empowerment of the farmworkers through capital appreciation and dividends was the most important motivation. Equity-sharing schemes are a relative new concept in farms that were included in this study and after the initial negative impact with the change in the management of the organisation, the schemes are faring good financially. / AFRIKAANSE OPSOMMING: Dit word algemeen erken dat die Suid-Afrikaanse kommersiële landboubedryf herstrukturering sal moet ondergaan om voorheen-benadeelde gemeenskappe by die landbou-ekonomie van die land te integreer. Dit is toe te skryf aan die ongelykhede wat ten opsigte van die landboubedryf tussen swart gemeenskappe en die tradisionele "blanke" landboubedryf bestaan. Na die bewindoomame van die ANC-regering in 1994, is maatreëls vir regstellende aksie ten opsigte van ongelykheid en onregverdige toegang tot hulpbronne en markte in werking gestelom hierdie ongelykhede uit die weg te ruim. 'n Kitsoplossing is egter nie moontlik nie; dit sal tientalle jare neem om die ongelykhede wat gedurende die apartheidsbewind geskep is, uit te wis. Die eerste plaaswerker kapitaaldelingskema is in 1992 op die Whitehall-plaas in die Grabouw-distrik van die Wes-Kaap ingestel. Die Suid-Afrikaanse Departement van Grondsake het hierdie strategie as een van die hoofprogramme vir grondherverdeling vir die ontwikkeling van die landboubedryf aanvaar, om basiese steun aan die plaasarbeiders te verleen om hulle in staat te stelom 'n deel in die finansiele belang van die kommersiële landboubedryf in Suid -Afrika te verkry. Die hoof navorsingsdoelwit van hierdie studie was om die uitwerking van die plaaswerker kapitaaldelingskema te evalueer en die bydrae van die program tot die verbetering van die lewenskwaliteit van voorheen-benadeelde individue, naamlik plaasarbeiders, te beoordeel. Dit is bewerkstellig deur middel van 'n opname wat die vyf plaaswerker kapitaaldelingskemas wat deur die Departement Grondsake se streekkantoor in Kaapstad geadministreer word, te betrek. Onderhoude is met gewone plaasarbeiders, lede van die raad van arbeidertrustees en die oorspronklike eienaars gevoer. Evaluering is onder andere gerig op die motivering agter deelname aan die skemas, kenmerke van die bestuur daarvan, sosio-ekonomiese faktore en die finansiële prestasie van die skemas. Dit het uit die ondersoek duidelik geword dat die oorspronklike eienaars die voortou geneem het met die inisiriëng van die kapitaaldelingskemas op hul plase. Werksekuriteit is as die belangrikste motivering deur plaasarbeiders gegee vir die deelneming aan die kapitaaldelingskemas, terwyl die ander deelnemers (oorspronklike eienaars) die aanvanklike kapitaal-inspuiting in die boerderyen die bemagtiging van die plaasarbeiders deur kapitaalappresiasie en dividende as die belangrikste motiverings aangedui het. Kapitaaldelingskemas is 'n relatiewe nuwe konsep by boerderye wat in hierdie studie betrek is en na die aanvanklike negatiewe bëinvloeding met die verandering in die bestuur van die organisasie, is die skemas besig om finansiël goed te vaar.

Evaluation of the performance of equity-sharing schemes administered by the Department of Land Affairs, Worcester district office of the Western Cape Province

Ralehoko, Enoch Ntala 12 1900 (has links)
Thesis (MAgricAdmin)--Stellenbosch University, 2005. / ENGLISH ABSTRACT: The study evaluated farmworker equity-sharing schemes administered by the Worcester regional office of the Department of Land Affairs in the Western Cape. The objectives were to investigate the performance of farmworker equity-sharing schemes against recent literature, to evaluate the motivation for the establishment of these schemes and whether they served the purpose for which they were established. Through investigating the role these schemes play in improving the farmworkers ' livelihood, the study investigated the changes farmworkers experienced on the farm since the establishment of the schemes. The perceptions of farmworkers regarding the schemes were also investigated. The study found that at all the farms evaluated there was a lack of formal training to all the levels of farmworkers, including committee members and shareholder workers. These farms did not have the funds to finance training programmes for their farmworkers. Poor training impeded farmworkers to utilise their skills and participate in decision making on the farm. Contrary to the objectives of financial participation and farmworker equity-sharing schemes, most of these schemes did not achieve the broad objectives of the participation schemes such as empowering their workers. Living and working conditions seem to have improved on most of the farms although some farms seem to have experienced no change at all. The ESTA Laws could be the cause of the improvements in housing and working conditions but not the implementation of the farmworker equity-sharing schemes. Respondents did not seem to experience discrimination due to gender. Financially the schemes are not performing well. This is evident from the number of schemes that were liquidated due to financial problems and for which financial statements could not be obtained. These schemes face various institutional and structural challenges, which includes financial challenges. / AFRIKAANSE OPSOMMING: Hierdie studie het plaaswerker-aandeelhouerskemas wat deur die Worcesterstreekskantoor van die Departement van Grondsake in die Wes-Kaap bestuur word, geëvalueer. Die oogmerke van die studie was om die verrigting van plaaswerkeraandeelhouerskemas teenoor onlangse literatuur te ondersoek, om die motivering vir die vestiging van hierdie skemas te evalueer en te bepaal of hulle wel die doel dien waarvoor hulle gevestig is. Deur die rol van hierdie skemas in die verbetering van plaaswerkers se bestaan te ondersoek, het die studie ook ondersoek ingestel na die veranderinge wat sedert die vestiging van die skemas deur plaaswerkers ervaar is. Die plaaswerkers se persepsies van die skemas is ook ondersoek. Die studie het bevind dat daar by al die plase wat betrek is 'n tekort aan formele opleiding aan al die vlakke van plaaswerkers was, met inbegrip van komiteelede en aandeelhouer-werkers. Hierdie plase het nie oor die fondse beskik om opleidingsprogramme vir hulle plaaswerkers te finansier nie. Swak opleiding strem plaaswerkers in die toepassing van hulle vaardighede en in hulle deelname aan besluitneming op die plaas. In stryd met die doelwitte van finansiële deelname en plaaswerker-aandeelhouerskemas het hierdie skemas nie in hulle doel geslaag nie. Woon- en werksomstandighede op die meeste plase het blykbaar sedert die vestiging van die skemas verbeter, alhoewel sommige plase skynbaar geen vemaderinge ondergaan het nie. Die Wet op die Uitbreiding van Sekerheid op Verblyfreg kan 'n verklaring vir die verbetering in behuising en werksomstandighede wees, en nie noodwendig die implementering van die plaaswerker-aandeelhouerskemas nie. Respondente het volgens alle aanduidings nie diskriminasie op grond van geslag ondervind nie. Die skemas presteer finansieel nie goed nie. Dit is duidelik uit die getal skemas wat as gevolg van finansiële probleme gelikwideer is en waarvoor finansiële state nie verkry kon word nie. Hierdie skemas staar verskeie institusionele en strukturele uitdagings in die gesig, waaronder ook finansiële uitdagings.

Biodiversity conservation and land rights in South Africa : whither the farm dwellers?

Crane, Wendy 12 1900 (has links)
Thesis (MPhil (Public Management and Planning))--University of Stellenbosch, 2006. / ENGLISH ABSTRACT: South Africa is unique in that its globally significant biodiversity, which is under major threat, coexists with an apartheid history of dispossession that produced a starkly unequal land ownership pattern and widespread rural poverty. It is in this context that the post-apartheid government must fulfil constitutional and international obligations to safeguard environmental assets as well as undertake land reform benefiting the previously dispossessed. Consequently, there is a continuous challenge of reconciling complex and often conflicting relationships between poverty, inequitable access to resources, and the protection of biodiversity. Current efforts to conserve the Cape Floral Kingdom emphasise partnerships between private landowners and existing nature reserves to promote sustainable utilisation of biodiversity. This paper explores the potential impact of this approach on farm dwellers, and how changing land use may affect their land tenure rights and livelihoods. Primary research was undertaken in the Baviaanskloof, where this model is in an early stage of implementation. The paper identifies systemic and structural tensions in current attempts to reconcile biodiversity conservation and farm dwellers’ interests, and documents issues of process and principle that could become important in the future. In doing so, it highlights the influence of on-farm power relations and highly complex institutional arrangements in determining the real extent of participation by affected farm dwellers and the efficacy of social safeguard policies. Findings also caution against an over-reliance on ecotourism as the major occupation and argues instead for support to multiple livelihood strategies.

Essays on nursery labor, sales contracts, and price discovery

Li, Cheng 18 March 2013 (has links)
Oregon's nursery and greenhouse industry has ranked the first in the State's agricultural for 18 years. The majority of nursery sales from the Pacific Northwest come from Oregon. Due to data limitations, empirical study of the Oregon nursery industry is rare. The present dissertation consists of three essays that analyze the demand and supply of inputs and outputs and the relationship between producers and retailers in the Oregon nursery industry. Chapter 2 identifies the major factors affecting farm labor supply and demand and evaluates their relative importance in the Oregon nursery industry from 1991 to 2008. Empirical results show that border control effort doesn't have an influential role in labor supply, while the Oregon and Mexican minimum wage do. It is because of the substantial gap between the U.S. and Mexican economies, reflected for an example in the minimum wage gap, which attracts a continual flow of immigrants. Risk of border apprehension is not great enough to prevent the flow. Increases in Oregon minimum wage is more effective than border apprehension policies in boosting the average wage and in reducing the number of hours that illegal immigrants work in the nursery sector. Chapter 3 investigates producers' and retailers' choices of, and reactions to, various contract types in the Oregon nursery industry from 2005 to 2010. As new and fast-growing retailers in the industry, big-box stores are less likely than independent retailers to make pre-order contracts with the producer. However, once a pre-order contract is chosen, big-box stores demand more days of pre-order interval than independent retailers do. Transactions with independent retailers exhibit – on average over the sample range – scale economies and scope diseconomies. Boosting per-transaction revenue scale and the number of species sold to big-box stores enhances transaction efficiency. Chapter 4 examines the interaction between supply and demand in Oregon nursery products. The result indicates that the production and transaction costs are major drivers on the supply side, while transportation costs and consumer demand for nursery products play important roles on the demand side. At the genus level, the supply elasticities of coniferous plants are larger than those of deciduous plants, which in turn are higher than those of flowering plants. The demand elasticities are the lowest in coniferous trees followed by deciduous plants, then flowering plants. Price discounts on plants with high demand elasticities would significantly boost sales and enlarge the market, while those on plants with low demand elasticities would have less sales impact. Empirically, patenting seems to bring no direct signs of greater profitability. The wholesale nursery may wish to reconsider the pricing and marketing policies of its patented plants to differentiate them more effectively from its non-patented plants. / Graduation date: 2013
