The three essays of this thesis cover two sets of topics: search in auction platforms in the first two papers, and political campaigning in the last. In platform settings, search cost reductions are often regarded as beneficial because they improve match quality. But is this in fact true? And if it is true in an aggregate sense, what are the consequences to individual platform participants? Do individual buyers and sellers win or lose? The first paper develops a novel model of search in platforms and applies it to auction platforms to test the popular hypothesis that lower search costs are always beneficial to sellers. Under certain assumptions, we find that while lower search costs is welfare improving, its distributional consequences are less predictable. In general, lower search costs intesify buyer-side competition. On the one hand, this tends to improve seller revenues due to better matches; on the other hand, this may also thin out markets for certain sellers, since lower search costs make it easier for buyers to search out of certain markets. Generally, some sellers gain and some lose; most surprisingly, however, we find that overall seller revenue can decrease with lower search costs. Our second paper extends the model to endogenize buyer participation - so some buyers may leave the platform completely - and considers optimal platform search policy in such settings. Under stricter assumptions, we find that a platform that taxes the seller side generally benefits from lower search costs; a platform that charges buyers, however, may maximize search costs, since the gains from easier search are unevenly distributed among buyers, and may be inefficiently extracted with a fee. The final essay provides a novel model of political campaigning as argumentation, which brings together two different strands of the campaign spending literature: spending has direct effects on electoral outcomes, but also provide a "signal" of candidate quality. The model parsimoniously resolves many pre-existing campaign spending "paradoxes" while delivering new results on the effects and desirability of spending caps. / Economics

Military spending briefly dipped in the early 1990s only to rebound by the end of the 20th century, yet policymakers and academics alike predicted a peace dividend if the cold war should end. What happened to this peace dividend? How do some countries actualize a peace dividend in a world that seems not to encourage one? Typically military spending is analyzed through lenses focusing on international politics, bureaucratic process, or domestic political economy. I argue that these three lenses have failed to account for some of the reasons military spending remains high in the post-cold war era. Utilizing sociological institutionalism and world models, I examine how the rules of the Washington consensus via the neo-liberal economic agenda and the national security exception promote high levels of military spending that the three main theories fail to recognize. This study particularly delves into the roles of states and transnational corporations in terms of competitiveness in the global political economy and privileges allotted to the military industry. My tests rely on fuzzy-set comparative qualitative analysis (fsQCA) as an innovative means for looking at necessary conditions as well as sufficient conjunctural causation through which countries can achieve a peace dividend in the post-cold war era.

This study concerns itself with the process of public sector resource allocation in Canada from 1965-1975. An examination of the Federal Government's own procedure manual for program evaluation, and the analysis of several program evaluations for Departments of Health, Education and Manpower, reveal that the analytical procedures and economic precepts used depart significantly from accepted norms of economic theory. Consequently, the rates of return claimed for these programs are distorted and, where they are used for the rationing of public sector resources, collective welfare will not be optimized. The major causes of these problems are improper analytical methodology and the failure to adhere to basic economic principles of resource allocation. Support for this hypothesis derives from accepted economic theory with respect to welfare maximization and the allocation of public expenditures.

The Government of National Unity, on coming into power in April, 1994, has endorsed the reconstruction and development programme (RDP) and its broad agenda for the rapid removal of the problems and gross inequality evident in all aspects of the South African society. Many economists argue that the sustain ability of the RDP, will depend crucially on the maintenance of fiscal discipline and the progressive reduction of the overall fiscal deficit. As excessive fiscal deficits are often associated with higher inflation, higher real interest rates, balance of payments disequilibrium and lower economic growth, thereby putting the RDP at jeopardy. The view based on the Ricardian Equivalence approach however, takes the position that neither deficits nor the way they are financed, is as critical to economic policy and the future prosperity of an economy, as is generally believed. The Ricardian view consequently, argues that government need not necessarily embark on deficit reduction programmes as advocated by the so called traditional view. The study investigates the validity of the Ricardian view, both on the empirical and theoretical side, with special reference to the South African economy. The specific question that this study attempts to address is whether economic agents behave in a Ricardian manner in the South African economy. Our results (based on the replication of the Dalamagas (1994) study) could be very consequential for South African policy makers, as they suggest that the Ricardian Equivalence proposition is valid and therefore, government could on purely theoretical grounds shift its focus away from the debt situation, and concentrate on the policies aimed to correct the inequalities (in wealth, distribution of public goods, employment opportunities) created by the Apartheid era. Whether government should do so in reality however is debateable due to the other considerations that government need to take account of when implementing actual macroeconomic policy. / Thesis (M.Soc.Sc.)-University of Natal, Pietermaritzburg, 1998.

This study examined how marital conflict and marital environment contribute to change in marital status over time; while controlling for gender and other demographic characteristics. The current study used all three waves, 1987-1988, 1992-1994, 2001-2002, of the nationally representative dataset National Survey of Families and Households (NSFH). Four longitudinal models were tested using path analysis and the Bayesian estimation technique. Findings indicate there is no effect of marital conflict on change in marital status when demographic and marital environment variables are in the model. Age has the strongest direct and indirect effects. An increase in number of times married consistently increases the chance of a change in marital status. Variables measuring the marital environment—with the exception of the effects of unfairness of chores and spending money in the male models—primarily, contribute direct and mediating effects on the two measures of marital conflict. Overall, when considering all models, the variable with the strongest direct and indirect effects, is age of the respondent. This finding indicates that the dominate influence on marital environment and marital conflict, and, ultimately, change in marital status, is that of age as a proxy for developmental change over the lifecycle.

An assessment of the costs and benefits of antiterrorism policies has a number of challenges. Canada’s situation is particularly complex because of its asymmetric and integrative economic and geographic relationship with the United States. Few theoretical models of international antiterrorism policy exist and none fit well this asymmetric relationship. This thesis attempts to fill this void by understanding the motives behind Canadian antiterrorism policies and the related spending, and how these are affected by the relationship with the United States. We explore a two country theoretical model with strategic interactions, focusing on relative spending. What is found is that the economics and geography of the two countries play a large role in motivating spending and can drastically alter antiterrorism spending beyond that needed solely for public safety in Canada. / Graduate / 0511 / 0501 / 0616 / kyleburak@gmail.com

The Klein Karoo National Arts Festival (KKNK) is one of the most popular arts festivals in South Africa, but ticket sales have alarmingly declined since 2005 resulting in the Festival already being in a decline phase of its product life cycle. This has a negative impact on the Festival's economic impact and future sustainability. It is therefore vital to increase the ticket sales in order for the Festival to maintain a steady growth rate. Market segmentation can assist the Festival's marketers/organisers to address this problem by identifying the high spending segment at the Festival since they stay longer and are keener to buy tickets supporting the Festivals shows/productions. Market segmentation is the process of dividing the festival market into smaller, more clearly defined groups that share similar, needs, wants and characteristics. The more detailed the knowledge of the needs and motives of potential visitors, the closer the Festival can get to a customised festival program creating greater satisfaction, long-term relationships, repeat visits and an increase in tickets supporting the shows/productions. The main purpose of this study was therefore to determine the spending behaviour of visitors the KKNK by means of establishing the determinants which influence visitor's expenditure and by applying expenditure-based segmentation in order to determine the high spending segment at the Festival. To determine the above goal, the study is divided into 2 articles. Research for both the articles was undertaken at the Festival and data obtained from 2005 to 2008 were used. Questionnaires were interview-administered and distributed randomly during the course of the Festival. In total 1940 questionnaires have been completed in the visitor survey since 2005. Article 1 is titled: "Socio-demographic and behavioural determinants of visitor spending at the Klein Karoo National Arts Festival." The main purpose of this article was to identify the various socio-demographic and behavioural determinants that influence visitor spending at the KKNK. This was done in order to determine which visitors spend most at the Festival and which determinants are most significant in determining their expenditure levels. A regression analysis was used as an instrument to achieve the mentioned goal. Results indicated that occupation, distance travelled, length of stay, the reason for attending the Festival and preferred type of shows/productions were significant determinants that influence the amount of money visitors spent at the Festival. These results generated strategic insights on marketing for the festival in order to increase visitor spending especially on purchasing more tickets for shows/productions. Article 2 is titled: "Expenditure-based segmentation of visitors at the Klein Karoo National Arts festival." The main purpose of this article was to apply expenditure-based segmentation to visitors at the KKNK in order to identify the high spending segment at the festival. An analysis of variance (ANOVA) was used to determine whether there were significant differences between the different expenditure groups. The Festival's market was divided into high, medium and low expenditure groups. Results revealed that the high spenders at the Festival were distinguishable from the low spenders based on their longer length of stay, older age, higher income, main reason to attend the Festival and preferred type of shows/productions. These results were used to compile a complete profile of the high spenders and how the Festival's appeal can be maximised in order to attract more high spenders. This research therefore revealed that certain socio-demographic determinants influence visitor's spending behaviour at the Klein Karoo National Arts Festival. There are further two distinct expenditure groups at the Festival, namely a high and low expenditure group. Knowledge of the determinants which influence visitor spending can be used in combination with the profile of the high spenders to maximise the Festival's appeal in order to attract more high spenders who buy tickets supporting the Festivals shows/productions. This will lead to an increase in ticket sales, a greater economic impact and ultimately to the continuous sustainability of the Klein Karoo National Arts Festival. / Thesis (M.A. (Tourism))--North-West University, Potchefstroom Campus, 2009.

The black middle–class market segment also known as the black diamond market segment has shown immense growth in SA. It currently consists of approximately 3 million black middle–class South Africans with a buying power of approximately R200 billion. Despite the immense size and spending power of black diamonds, combined with its rapid growth over the past 15 years and expected future growth, little research has been conducted on this market segment. The rapid market growth of the black diamond market segment has lead to an immense rise in the demand for middle–income houses. This has caused a shortage of middleincome houses, and government and real estate developers have been unable to supply housing in this bracket to meet this ever increasing demand. The study examines this missing middle between supply and demand for the black diamond market in Tlokwe municipal region in order to provide the Tlokwe Municipality, real estate developers, construction companies, town planners, real estate agencies and the Tlokwe Department of Housing with sufficient information to address this challenge in Tlokwe municipal region. The study was conducted by way of a literature review and empirical study. For the empirical study, the information was obtained through two questionnaires. One questionnaire was compiled for black diamond respondents and one for real estate developers and estate agents in the Tlokwe municipal region. The study found that there is a gap between the supply side and demand side of middleincome housing (houses within the R50 000 to R550 000 price range) in the Tlokwe municipal region, and that there is a high demand for such houses. It was also found that there is a tendency for black diamonds to relocate from the townships to the suburbs. The major reasons for this movement were identified as family and the lack of availability of middle–income houses in the townships. It was also found that the black diamond respondents have a tendency to spend their money on bad debt (debt on expenses) instead of good debt (debt on assets), and are inclined to save rather than spend. Furthermore, as evident from the number of respondents with clothing accounts and cellphone contracts, it was confirmed that black diamonds are status driven, as suggested in the literature. / Thesis (M.B.A.)--North-West University, Potchefstroom Campus, 2011.

Sport tourism, as a segment of tourism, is one of the fastest growing industries. Sport events have grown enormously over the last two decades and, as a part of sport tourism, they are a very powerful tool that is used to market a country. Sport tourism also creates an internationally recognised image and attracts tourists from all over the world. One of the internationally recognised sport events held annually in Cape Town is the Pick In Pay Cape Argus Cycle Tour (ACT). Originally started in 1977, it has grown to attract 32 000 cyclists by 2008. However, as with any event, the ACT's life cycle reached a climax and is currently on a downward slope, in terms of participation figures. This decline was the motivation for starting this study. As such, it was determined that the goal of this study would be to profile the participants in the ACT as this information could provide some of the reasons for the decline in numbers. In order for the researcher to successfully profile the participants, three objectives were formulated. Firstly, the reasons why cyclists participated in the ACT, in other words their travel motives, were examined. Secondly, it was determined which variables had a significant influence on cyclists' spending behaviour while visiting Cape Town. Finally, conclusions and recommendations were presented, and a profile of the participants was compiled. The research was done by means of using a questionnaire with three sections. The first section sought demographic information while section B measured the spending behaviour of the respondents. The last section established what motivated the cyclist to participate in the ACT. The survey took place from 5 - 8 March 2008 during the registration period at the Good Hope Centre of the city of Cape Town. A total of 583 completed questionnaires were received by the fieldworkers. The data analyses were then performed by firstly capturing the data into a Microsoft Excel spreadsheet. The statistical program, SPSS, was then used for the further analyses. A factor analysis was performed in order to achieve the first objective of determining what motivated cyclists to participate in the ACT. Then a regression analysis helped to establish which variables influenced cyclists' spending. After all the analytical procedures were completed, the results of the factor analyses indicated the cyclists were motivated by the attractiveness of the event, by personal motivation and by a desire to escape from the daily routines and so to relax. The regression analyses lead to the results that the following variables determine how much money cyclists spend; marital status; province of residence; the number of nights stayed in Cape Town and which accommodation cyclists used. These results both confirmed and contradicted the results of previous research, even though this was the first time this type of research had been applied to a sport event in South Africa. This research can be used by event organisers to apply more effective target marketing and to develop new strategies to encourage an increase in participation figures. This research can also be used to improve business relationships between the different role players in an event. Further, product improvements can be made from certain recommendations. / Thesis (M.Com. (Tourism))--North-West University, Potchefstroom Campus, 2010.
