Latin America major player in the international financial markets, agony and ecstasy

This study deals with the complex relationship between the International Financial Markets (IFMs) and the countries of the Latin America Group, emphasizing the entrance and the exit conditions for these countries in the last two indebtedness cycles - 1967/1982 and 1990/1994. Finally, it makes some considerations about the consequences of these Latin America countries of being linking economic policies to the external financing abtained in the IFMs.

Financial frictions, informality and income inequality

We studied the effects of changes in banking spreads on distributions of income, wealth and consumption as well as the welfare of the economy. This analysis was based on a model of heterogeneous agents with incomplete markets and occupational choice, in which the informality of firms and workers is a relevant transmission channel. The main finding is that reductions in spreads for firms increase the proportion of entrepreneurs and formal workers in the economy, thereby decreasing the size of the informal sector. The effects on inequality, however, are ambiguous and depend on wage dynamics and government transfers. Reductions in spreads for individuals lead to a reduction in inequality indicators at the expense of consumption and aggregate welfare. By calibrating the model to Brazil for the 2003-2012 period, it is possible to find results in line with the recent drop in informality and the wage gap between formal and informal workers

Primed and prejudice: the Kurantha-Bothata study

O sistema de peer review é uma ferramenta fundamental nas publicações científicas, cujo objetivo é selecionar os estudos que contribuem para o avanço do conhecimento. No entanto, questionamentos tem surgido acerca de vieses no sistema de peer review. Um exemplo é o estudo "Lost science in the third world" (Gibbs, 1995), que afirma existirem sérios vieses em relação à origem dos pesquisadores. Ainda que haja evidências para suportar esse argumento, nosso conhecimento acerca de vieses no sistema de peer review ainda é limitado, já que poucos estudos controlados podem ser encontrados na literatura. No presente trabalho, foi realizado um exeprimento no qual os sujeitos deveriam avaliar um artigo sem qualquer identificação de autoria, exceto por uma nota de rodapé onde constava o nome da instituição fictícia que financiou a pesquisa. Sob uma condição, o nome da agência financiadora é associado com o continente africano, enquanto na outra condição, o nome da agência é associado ao continente europeu. Os resultados dão indícios de que possa haver um viés relacionado às origens do autor.

Mobility, targeting and private school vouchers

This paper uses general equilibrium simulations to explore the role ofresidential mobility in shaping the impact of different types of private school voucher policies. In particular, general vouchers available to all residents in the state are compared to vouchers specifically targeted to either underprivileged school districts or underprivileged households. The simulations are derived from a three-community mo deI of low, middle and high income school districts (calibrated to New York data), where each school district is composed of multiple types of neighborhoods that may vary in house quality as well as the leveI of neighborhood extemalities. Households that differ in both their income and in the ability leveI of their children choose between school districts, between neighborhoods within their school district, and between the local public school or a menu of private school altematives.Local public school quality within a district is endogenously determined bya combination of the average peer quality of public school attending children as well as local property and state income tax supported spending. Financial support (above a required state minimum) is set by local majority rule. Finally, there exists the potential for a private school market composed of competitive schools that face production technologies similar to those ofpublic schools but who set tuition and admissions policies to maximize profits. In tbis model, it is demonstrated that school district targeted vouchers are similar in their impact to non-targeted vouchers but vastIy different from vouchers targeted to low income households. Furthermore, strong migration effects are shown to significantly improve the likely equity consequences of voucher programs.
