The theory of storage and the volatility in commadity markets

Esse estudo estende a metodologia de Fama e French (1988) para testar a hipótese derivada da Teoria dos Estoques de que o convenience yield dos estoques diminui a uma taxa decrescente com o aumento de estoque. Como descrito por Samuelson (1965), a Teoria implica que as variações nos preços à vista (spot) e dos futuros (ou dos contratos a termo) serão similares quando os estoques estão altos, mas os preços futuros variarão menos que os preços à vista quando os estoques estão baixos. Isso ocorre porque os choques de oferta e demanda podem ser absorvidos por ajustes no estoque quando este está alto, afetando de maneira similar os preços à vista e futuros. Por outro lado, quando os estoques estão baixos, toda a absorção dos choques de demanda ou oferta recai sobre o preço à vista, uma vez que os agentes econômicos têm pouca condição de reagir à quantidade demandada ou ofertada no curto prazo.

International private equity funds strategies in the Brazilian market

The Private Equity Market in Brazil has flourished in the last two decades, and international Funds have been entering the market since then. The activity of these enterprises and how they deal with institutional voids that are present in the brazilian market and the all spheres of distances they have with Brazil are investigated in this research. What are the main challenges for those players in the local market and how private equity functions in Brazil? The first chapter reviews all the literature that concerns private equity in their home countries, such as the United States and Spain (Europe) and Brazil. It also discourses about the concept of private equity in all its different senses, the routine of investees and how is the relationship between Private Equity Fund and Investee. In addition to that, the due diligence process is also explained as well as the private equity sector in Brazil and its regulation. Moreover, the distance between countries and how it affects business is presented followed by the concepts of institutional voids. For the inquiry proposed interviews were conducted in order to capture the perspective of International Private Equity Funds on the Brazilian market. Advent International, The Carlyle Group and Mercapital replied to the inquiries and provided the tools so a picture of the sector was developed. This sector has a range of challenges and opportunities and requires the International Fund to establish a local branch in order to really succeed in the market. The results of this project pointed out to the challenges the market presents and how International Private Funds are coming about it. There are definitely gaps that need to be fulfilled however the industry is going in the right direction. Revenues may change its nature in the next couple of years, however from the Private Equity Fund perspective Brazil has been a worthwhile investment. Nonetheless, it is important to question the vision also of the investee and institutional investor so one can have the entire picture of the sector.

A bidimensional model of matching in the marriage market with women labor decision

We construct a frictionless matching model of the marriage market where women have bidimensional attributes, one continuous (income) and the other dichotomous (home ability). Equilibrium in the marriage market determines intrahousehold allocation of resources and female labor participation. Our model is able to predict partial non-assortative matching, with rich men marrying women with low income but high home ability. We then perform numerical exercises to evaluate the impacts of income taxes in individual welfare and find that there is considerable divergence in the female labor participation response to taxes between the short run and the long run.
