    The Cross-Sectional Determinants of Returns: Evidence from Emerging Markets' Stocks

    Get PDF
    This paper looks at the cross-section of stock returns for the particular case of emerging markets. For each of 21 emerging markets I investigate the role of a set of a priori specified factors in the cross-section of returns, and subsequently assess whether the important factors are common. I use data on emerging markets’ individual stocks from the Emerging Markets Data Base (IFC). My results indicate that the most important pricing factors are common to the emerging markets in my sample, and that these important factors are similar to those identified for mature markets. Among the top six factors are technical factors and price level attributes. The payoffs to these factors are not correlated suggesting that even if investors across markets elect similar factors to price assets, premia are local.International Asset Pricing; Emerging Markets

    Abnormal Returns in Privatization Public Offerings: The case of Portuguese firms

    Get PDF
    This paper provides evidence on abnormal returns of Portuguese privatization public offerings for the period from 1989 to 2001. This study explores the abnormal performance of a comprehensive sample of Portuguese privatization transactions and investigates the determinants of the observed price behavior. We find some evidence of the underpricing phenomenon for privatized offerings but initial returns are low and barely significant. The results show further that privatization IPOs underperform private sector IPOs. In the long run, we observe negative abnormal returns. While in early event months, privatization public offerings yield more negative returns than private sector offerings, this effect is reversed in longer horizon periods. Initial underpricing is thus partially reversed and investors seem to require higher returns in partial privatizations.

    Market Impact of International Sporting and Cultural Events

    This paper investigates the impact of international sporting and cultural events on national stock markets. We study market reaction to the announcements of the selected country hosting the Summer and Winter Olympic Games, the World Football Cup, the European Football Cup and World and Specialized Exhibitions. We also measure the market effects of the announcement of the nomination of the European Cultural City. First, we evaluate the abnormal returns of winning bidders at (and around) the announcement date using an event study methodology. We study the impact at market and industry-levels. Second, we analyze the determinants of the variation in abnormal returns across events and industries on the basis of a set of variables found important by previous studies and control for the prior probability of observing the event. Third, on the basis of a simple model of partial anticipation, we reexamine the abnormal returns observed for the winning and losing countries and perform a series of tests to disentangle the different theoretical arguments that could account for the observed stock market behavior. Our initial results suggest that the abnormal returns measured at the announcement date and around the event are not consistently different from zero. Further, when we look at particular industries, we find no evidence supporting that industries, that a priori were more likely to extract direct benefits from the event, observe positive significant effects. Yet when we control for the prior expectations, the announcement of these mega-events is associated with a positive market reaction in the nominated country and a negative reaction in the losing country. Overall we interpret our findings as supportive of rational asset pricing and partial anticipation.Market efficiency; Event studies; Mega-events

    Tests of international capital market integration: evidence from emerging stock markets

    Get PDF
    The central theme underlying my thesis is Emerging Stock Markets and my dissertation consists of three empirical essays regarding International Asset Pricing. I focus my research on emerging markets and stress how the new and extensive data provide additional insights on International Capital Market Integration and Portfolio Diversification issues. My first essay tests whether an International Asset Pricing theory can account for the time-series as well as cross-sectional variation in discounts. I use an extensive new data set on US, UK and off-shore emerging markets' country funds. I find that changes in discounts are significantly and positively correlated with the fund's exposure to the world market factor but I find no significance for the underlying assets' exposure to the local market factor. The evidence is also inconclusive regarding the effects of barriers to free investment. Overall, my results suggest that segmentation of capital markets is insufficient to explain the time-series and cross-sectional variation in country funds' discounts. My second essay examines how the dual-listing of emerging markets' stocks affects their valuation and studies the link between these effects and market segmentation. My empirical results are based on dual-listings of emerging markets' stocks on US and London exchanges. Firms experience significant positive abnormal returns before the listing date and a significant decline in returns over the first five weeks following listing. The valuation impact is similar across exchanges and more pronounced for emerging markets' firms. Overall, the results are consistent with the market segmentation hypothesis. My third essay analyses the influence of industrial factors on the cross-sectional variance and correlation structure of country index returns for the particular case of emerging markets. In addition, I investigate, for each market, the role of a set of a priori specified factors in the cross-section of stock returns, and assess whether those factors are common to the universe of emerging markets. My sample consists of all the individual stocks composing the IFC emerging markets' indices. Country effects are the most important factors driving the behaviour of emerging markets' individual stock returns. A finer industry partition shows, however, that ignoring the industrial mix will lead to an important loss of diversification benefits. Furthermore, my results indicate that the most important pricing factors are common to emerging markets. Yet the payoffs to these factors are uncorrelated. Altogether, the empirical results are consistent with market segmentation

    Impacto da conclusão da graduação em funcionários administrativos de uma faculdade particular do DF

    O presente estudo teve como alicerce principal a Psicodinâmica do Trabalho. Através da pesquisa exploratória procurou-se responder o seguinte problema de pesquisa: qual o impacto da conclusão da graduação em funcionários administrativos de uma faculdade particular do DF? Os objetivos específicos da pesquisa foram: descrever o trabalho prescrito, identificar o trabalho real e analisar sobre a manutenção desse funcionário. Os dados da pesquisa foram coletados através de entrevistas semiestruturadas, realizadas com quatro funcionários da faculdade em questão e posteriormente transcritas e analisadas pela analise de conteúdo. Eles gostam do ambiente de trabalho, valorizam a cultura da empresa, mas estão insatisfeitos com a remuneração salarial que não condiz que o serviço real e com a falta de oportunidade de crescimento dentro da empresa

    Narrativas entrelaçadas no ensino superior - Como nos constituímos enquanto comunidade e produzimos colaborativamente conhecimento emancipatório sobre investigação baseada em artes?

    ABSTRACT. This article sets up a collaborative narrative of three elements from the Group Study on Participatory and Artistic Processes in Research and Education (GEPPAIE), composed of researchers in academic and professional development (professors, doctoral and master's students in Education areas). It begins with a question: how have we experienced, as a higher education study group, our meeting spaces for the production of emancipatory knowledge about research, especially about arts-based research? This question unfolds into others and drives us to what has already been produced collectively, but also boosts the new writings and reflections in this text. It is also part of Ana Serra Rocha's PhD, focused on the problematization of The book’s experience as a place of epistemological reflection in artistic education, aiming at a broader reflection in the field of artistic education and in doctoral studies. It speculates on the participatory processes of collaborative creation and on some issues that have been debated at GEPPAIE, namely of a relational and methodological nature, with a view to (des/re)construction of knowledge and its forms of written and visual representation.ABSTRACT.
