Hårdnande konkurrens i en globaliserad och teknologidriven arbetsmarknad föranleder ökade krav på flexibla affärsmodeller för allt fler arbetsgivare. Atypisk arbetskraft används som en reserv för att möta marknadens fluktuerande behov och som en buffert för fast anställda vilket förklaras ge upphov till ojämlika arbetsförhållanden och segmentering av arbetskraften i ”insiders” och ”outsiders”. Denna studie ämnar bidra till att fylla den kunskapslucka som finns avseende flexibilisering i den svenska arbetsmarknaden genom att studera skillnader i arbetstillfredsställelse mellan fast och atypiskt anställda och därtill den medierande effekten av lön och arbetsotrygghet. Studien utgår från Dual Labor Market Theory vilken dikotomiserar arbetsmarknaden i ett primärt och sekundärt segment med starka institutionella barriärer emellan. Arne Kallebergs teori om arbetsbelöningar utgör utgångspunkt för studiens teoretisering och operationalisering av arbetstillfredsställelse. Datamaterialet baseras på den sjätte europeiska undersökningen om arbetsvillkor, EWCS6, 2015. Analysen utgår från totalt 807 anställda män och kvinnor mellan 18–65 år som vid datainsamlingstillfället var folkbokförda i Sverige. Med bivariata analyser visas att atypiskt anställda har lägre lön och upplever en högre arbetsotrygghet än fast anställda. Genom enkel och multipel regressionsanalys visas att atypisk anställning är negativt associerat med arbetstillfredsställelse och att lön medierar det negativa sambandet. Resultaten går i linje med tidigare forskning som visat negativ inverkan av atypisk anställning på arbetstillfredsställelse och lön samt ger stöd åt Dual Labor Market Theory genom att påvisa strukturella komponenters betydelse i sammanhanget. Otrygghet i arbetet visas ha svag inverkan på arbetstillfredsställelse och obefintlig medierande effekt på sambandet mellan atypisk anställning och arbetstillfredsställelse vilket strider mot tidigare forskningsresultat och diskuteras med hänsyn till det ekonomiska skyddsnät som innefattas i svensk socialpolitik däribland A-kassa, socialbidrag och statligt finansierade basutgifter.

This study addresses the empirical question of heterogeneous market efficiency characteristics, specifically as they are attributable to divergent levels of professional securities analyst attention. As a significant group of information intermediaries, analyst institutions conceivably influence, in a profound manner, the efficiency with which security prices respond to new information. Consistent with this notion is the hypothesis that the securities of firms which are neglected in terms of analyst coverage exhibit price inefficiencies relative to their closely followed counterparts. Two market efficiency constructs with respect to annual earnings announcements are examined in this study. Preannouncement information efficiency is guaged by the degree to which security prices appear to lead or anticipate the information content of subsequent public earnings releases. Such price behavior is indicative of the market's ability to acquire and, process interim, signals that are relevant to the determination of proper and timely security valuations. Postannouncement, or semi-strong-form, efficiency is in turn referenced by the relative absence of anomalous "drifting" patterns in postdisclosure returns. The presence of significant drifts is inconsistent with a market that adjusts quickly and unbiasedly to signals that are transmitted publicly. Sample firms taken from the NYSE are ranked into three groups according to their relative following by the professional securities analyst community. Analyst attention is surrogated by the number of investment houses providing annual earnings per share forecasts for companies listed in the Institutional Brokers Estimate System (IBES) computer file. The delineation of the three attention concentration groups' relative efficiency profiles is accomplished by means of two uniquely derived metrics that restate cumulative abnormal returns (CAR's) into an ordered domain of pre- and postannouncement efficiency structures. The CAR's are derived from dailly price data immediately surrounding annual earnings announcement dates for the calendar years ended 1976 through 1982. Owing to the nonnormal distributional properties of the inefficiency metrics, two nonparametric procedures are employed to detect group mean differences. The results overwhelmingly indicate that both pre- and postannouncement efficiency are positively associated with professional analyst attention. Moreover, the detected efficiency differences cannot be attributed to firm size effects or to the extent of the market's forecast error -- two factors that have previously been established in the empirical literature to be associated with event period CAR magnitudes. / Ph.

In the first part of thesis, we investigated the influence and explanatory power of aggregate insider trading activities on momentum trading strategies in US stock markets. We find that aggregate insider trading activities have ability in predicting cross-sectional returns and can strengthen the naive momentum effects. The risk factors such as size and book-to-market ratio cannot explain the strong momentum effects in our refined momentum strategies. We further extend the time horizon to as long as 3 years and find that the reversal patterns. We interpret our findings as follows: The continuous overreaction causes the mediate term (3- to 12 months) momentum effects and overly pricing. In long-term horizon, these overly priced stocks will be corrected with the time passing. The correction of overly pricing causes long-term reversals. / In the second part of the thesis, we studied relationships between the efficiency of external market and the capital allocation processes in internal market by investigating the performance of red chips traded in Hong Kong. Because of its special role between China and international capital market, it is difficult for international investors to monitor how red chips allocated their Hong Kong raised capital in China. The evidences show that red chips made poor investments in the past decades. However, the external market failed to reflect the unprofitable investment made by the management groups in the internal market. At least, our evidences show that the red chips made diversified but unprofitable investments in aggregate level in the past decade. / Jihong Xiang. / "December 2001." / Source: Dissertation Abstracts International, Volume: 63-01, Section: A, page: 0306. / Supervisors: Jia He; Duan Li. / Thesis (Ph.D.)--Chinese University of Hong Kong, 2001. / Includes bibliographical references (p.102-113). / Available also through the Internet via ProQuest dissertations and theses under title: Are markets efficient?

Market abuse practices may directly or indirectly give rise to diverse problems such as inaccurate stock market prices, low public investor confidence, reduced market integrity and poor efficiency in the affected financial markets. This thesis reveals that three major forms of market abuse, namely insider trading, prohibited trading practices (trade-based market manipulation) and the making or publication of false, misleading or deceptive statements, promises and forecasts relating to listed securities (disclosure-based market manipulation) are prohibited in South Africa. However, although South Africa has had market abuse legislation for about 30 years, and must be commended for its great effort to enhance market integrity by combating market abuse practices, the enforcement of such legislation is still problematic. Moreover, in spite of the fact that there is no empirical data or accurate figures quantifying the occurrence and extent of market abuse activities in the South African financial markets, this thesis submits that market abuse practices are still to be completely eradicated. Accordingly, this thesis suggests that the aforementioned problem might have been aggravated by inter alia, various gaps, flaws and/or inconsistent implementation and enforcement of the market abuse legislation in South Africa. To this end, the anti-market abuse enforcement framework under the Securities Services Act 36 of 2004 is analysed to investigate its adequacy. The co-operation and role of the Financial Services Board, the courts, the Directorate of Market Abuse and other relevant stakeholders is also examined and discussed. Moreover, the co-operation between the Financial Services Board and similar international agencies is discussed to gauge its effectiveness in relation to the combating of cross-border market abuse practices. The adequacy of the awareness and preventative measures in place to curb market abuse practices is also investigated to determine whether such measures are robust enough to combat other new challenges that were posed by the 2007 to 2009 global financial crisis. Furthermore, a comparative analysis is undertaken of the enforcement of the market abuse prohibition in other jurisdictions, namely the United States of America, the United Kingdom, the European Union and Australia. This was done to investigate the relevant lessons that can be learnt or adopted from these jurisdictions. The thesis further discusses the adequacy of the recently introduced provisions of the Financial Markets Bill as well as the subsequent market abuse provisions of the Financial Markets Bill 2012. The thesis highlights that the aforementioned Bills are positive attempts by the policy makers to improve the enforcement of the market abuse provisions in South Africa. Nonetheless, the thesis reveals that most of the shortcomings contained in the Securities Services Act 36 of 2004 were duplicated in the Financial Markets Bill and the Financial Markets Bill 2012. In light of this, it remains to be seen whether the market abuse provisions contained in the Financial Markets Bill and/or the Financial Markets Bill 2012 will improve the combating of market abuse practices in South Africa. Consequently, it is hoped that the relevant market abuse provisions of the Securities Services Act 36 of 2004, the Financial Markets Bill and/or the Financial Markets Bill 2012 will be comprehensively reviewed in regard to the recommendations made in this thesis. To this end, the thesis proposes a viable anti-market abuse model and policy framework and sets out both policy objectives and provisions which policy makers could use to strengthen some of the market abuse provisions in South Africa.

This diploma thesis is devoted to the problem of creating a portfolio of shares. First part is focused on the characterization of shares - classes of shares and rights associated with them. The second chapter compares the Efficient market theory and Behavioral approach, as the two opposing schools of thought. The third chapter gradually introduces fundamental analysis, from the global analysis through the analysis of an industry to the analysis of a particular company. Furthermore, this work focuses on the Value investment approach, that is based on fundamental analysis. On the basis of several criteria are particular stocks selected to the portfolio. The intensity of these criteria is then tested in the relationship with the resulting number of selected stocks. The conclusion of the fourth chapter is devoted to the issue of discounts and premiums that are trying to take into account specific factors of securities, which should be reflected into their prices.
