The high level of inequality in South Africa remains one of the biggest problems facing the country. Inequality is not limited to income and can be found in infrastructure, health and education as part of the heritage of apartheid. Polarisation is related to inequality with increases in high- and low-earning jobs, while middle-earning jobs remain stagnant or even decline. This study will try to identify polarisation in the South African labour market since the end of apartheid by making use of the Post-Apartheid Labour Market Series that uses a compilation of Statistics South Africa data ranging from 1994 to 2012. The study finds some evidence of polarisation of employment and earnings in South Africa and the growth of the tertiary sector and the public sector in the country has meant gains in the middle of the distribution for people with a Grade 12 education. Relatively strong unions and the introduction of minimum wages have helped those at the bottom to catch up with the middle. / MCom (Economics), North-West University, Potchefstroom Campus, 2015

Text in Afrikaans / Summaries in English and Afrikaans / The orthodox school's explanation for wage differentials, unemployment and labour market discrimination and the policy measures which they proposed did not offer workable solutions to the problems of the day. During the late 1960s and early 1970s a group of American labour economists conducted field studies in American urban ghettos which resulted in the formulation of the dual labour market theory. In contrast with the orthodox approach, which emphasises free market forces and investment in human capital, the dual labour market theory focuses on the dual structure of the labour market. The labour market is divided between a primary (high-wage) and a secondary (low-wage) sector, with little or no mobility between the sectors. An oversupply of labour in the secondary sector and unemployment are the results. These labour market phenomena and dualism also characterise the South African labour market and should be taken into account when policy measures are formulated. / Loonverskille, werkloosheid en arbeidsmarkdiskriminasie is algemene verskynsels in arbeids· markte wereldwyd.

In teenstelling met die ortodokse benadering, wat Idem le op die werking van vrye markkragte en investering in menslike kapitaal, benadruk die dualistiese arbeidsmarkteorie die tweeledige struktuur van die arbeidsmark. Die arbeidsmark is verdeel tusssen 'n primere (hoogbesoldigde) en sekondere (laagbesoldigde) sektor, met min of geen mobiliteit tussen die sektore nie. Werkers se toegang tot die primere sektor word beperk, met 'n ooraanbod van arbeid in die sekondere sektor en werkloosheid as die gevolg. Hierdie arbeidsmarkverskynsels en dualisme is ook kenmerkend van die Suid·Afrikaanse arbeidsmark en beleidsmaatreels moet daarmee rekening hou / Economics and Management Sciences / M. Comm.

This dissertation presents an exploration of the use of nonparametric statistical methods based on ranks for use in financial market research. Applications to event study methodology and the estimation of security systematic risk are analyzed using a simulation methodology with actual daily security return data. The results indicate that procedures based on ranks are more efficient than normal theory procedures currently in common use.

An alternative way to invest on the stock market is to invest in IPO’s. An IPO (InitialPublic Offering) is the first time a company goes public on a stock market, giving outshares to private investors and financial institutions. However, there might be someuncertainties about the share price as it never has been traded on the stock exchangebefore and it could therefore be difficult to determine a reasonable value for the shareprice. Consequently, if the offering price for the investor is significantly lower thanthe “correct valued” price it will generate positive initial return during the first tradingday and this phenomenon is labelled as underpricing, generating more “money on thetable”. Still, previous researches display an underperformance among IPO’s during alonger period after the introduction compared to already established companies withinthe same sector, arguing that investors should sell their shares early after the firsttrading day.The objective of this study is therefore to determine if underpricing exists for IPO’son the Swedish stock exchange and if there are any differentiations amongst sectors,and also to investigate two different Buy-and-Hold strategies. A final objective for thestudy is to determine if the level of underpricing is affected by some explanatoryvariables.With a quantitative study and a longitudinal approach, the results confirm the effect ofunderpricing for IPO’s on the Swedish stock exchange, generating an averageunderpricing of 5.56%. Additionally, this study cannot display any different medianunderpricing between industry sectors. However, it contradicts with theunderperformance phenomenon, indicating an overperformance for longer Buy-and-Hold strategies. Lastly, a regression of explanatory variables trying to explain thelevel of underpricing demonstrates no statistically significant results.

Master of Science / Department of Journalism and Mass Communications / Angela Powers / Technological revolutions of the past century have fueled dynamic paradigm shifts across a broad spectrum of mass media industries. This study examines an innovative new market segment in the music recording industry: digital music aggregation. Digital music aggregators are music distributors that directly connect artists, any creator of musical content, to digital music vendors, online music stores such as iTunes or digital music streaming services such as Spotify. Digital music aggregator companies offer services similar to major record labels, such as mass distribution, royalty collection, and intellectual property protection. Digital music aggregators provide services to artists at all levels of prestige and experience. Essentially any artist interested in publishing music can do so using digital music aggregators. Despite their growing influence in the music recording industry, digital music aggregators have been afforded little scholarly attention. This study responds to Galuszka's (2015) call for further research on aggregator market structure and competition, proposing the following research questions: 1) how is the digital music aggregator market structured? 2) What competitive strategies do digital music aggregators employ? This study is framed by the industrial organizational model of market structure (Bain, 1968) and Porter’s (1980) theories of competitive strategy. Six in-depth qualitative interviews were conducted for this study. Results illuminate market structure and competitive strategies in the digital music aggregation industry and lay foundation for future study and industrial application within this nascent branch of the music recording industry.

Some corporate insiders hold insider equity holdings in multiple companies (portfolio insiders). I hypothesize that information can be garnered not only from their trades (e.g., an insider sale of firm A on day t), but from their not-traded securities (e.g. the insider's decision not to sell firms B and C on day t). Specifically, an insider's decision not to sell (purchase) security B at the time of the sale (purchase) of security A, is a positive (negative) signal for security B, the not-sold (not-bought) security. The paper presents three major empirical findings. First, portfolio insider not-sold securities following a sale earn large risk-adjusted returns outperforming the not-purchased securities following a purchase. Second, portfolio insiders' purchases are more informative than single-firm insiders' purchases. Finally, the results suggest that abnormal returns associated with insider purchases result from markets reacting to the revelation of the insider purchase while abnormal returns associated with not-sold securities appear to result from insiders delaying sales prior to positive firm-specific events.

While the majority of the literature on secondary markets for tickets in the entertainment industry focuses on concerts and sporting events, this study aims to shed light specifically on the music festival resale market. Music festivals have risen in prominence in recent years, particularly among millennials, during the time that the internet has dramatically facilitated the resale of tickets through online marketplaces. With many of the top festivals selling out rapidly, a great deal of music fans turn to secondary markets for tickets. However, very little is known about the behavior of secondary markets for music festivals due to information not being readily available to the public. This study uses demand-side data including transaction prices and quantities acquired from one of the largest online secondary ticket marketplaces to examine market behavior. My findings show that on average, prices decline for music festivals as they approach, but that there are years for certain festivals where this isn’t the case. Other results show that markets for festivals with multiple weekends operate differently and that special artist performances such as band reunions can have a significant positive effect on consumer demand. Lastly, the majority of all ticket sales are found to take place in the final 30 days before music festivals transpire.

This study intends to scrutinize how adjustments made in the housing market has affected the profession of estate agents. Our premise is based on that social facts can be interpreted by social facts and the aim is to understand the factors affecting the profession in today's society that are developed in interaction with societal factors. In order to fathom this phenomenon, we have chosen to study the profession of estate agents and how it has been affected by the housing market. The empirical material is based on real estate agents’ experience and is therefore collected through a qualitative method based on interviews. The study is interpreted by a professional theoretical perspective, where we have assumed the thesis that all professions can be professionalised. The theoretical conceptual apparatus consists of autonomy, social closure, legitimacy, authority and will be used to understand the professionalisation process, that is when and why professions arise. Despite the fact of the profession’s changes, it has not been enough for the profession to be professionalised in the classical term. It can be said that the housing market has affected the professionalisation process of profession of real estate brokerage, which means that social factors can influence the professionalisation process. What prevents the profession from change and development of their professional position is the lack of autonomy. Due to the runaway housing market, a regulator was established to combat irregular transactions, which lead to decreased autonomy. A stronger professional status would derive from an increased authonomy and the conclusion is therefore that as long as the profession is under external control, it will not be professionalised.
