Equity-premium puzzle: evidence from Brazilian data

This paper uses 1992:1-2004:2 quarterly data and two di§erent methods (approximation under lognormality and calibration) to evaluate the existence of an equity-premium puzzle in Brazil. In contrast with some previous works in the Brazilian literature, I conclude that the model used by Mehra and Prescott (1985), either with additive or recursive preferences, is not able to satisfactorily rationalize the equity premium observed in the Brazilian data. The second contribution of the paper is calling the attention to the fact that the utility function may not exist if the data (as it is the case with Brazilian time series) implies the existence of states in which high negative rates of consumption growth are attained with relatively high probability.

The role of bond covenants and short-term debt: evidence from Brazil

Esta dissertação tem como objetivo analisar a relação entre covenants e alavancagem financeira no curto e longo prazo com oportunidades de crescimento. A partir de uma amostra de 159 debêntures, encontramos evidência de que: 1) Covenants e dívida de curto-prazo podem ser considerados substitutos na atenuação do conflito de agência, uma vez que apresentaram relação negativa e significante e; 2) A relação negativa existente entre dívida de curto prazo e oportunidades de crescimento pode ser reduzida através da utilização de covenants.

New evidence of the causal effect of family size on child quality in a developing country

This paper presents new evidence of the causal effect of family size on child quality in a developing-country context. We estimate the impact of family size on child labor and educational outcomes among Brazilian children and young adults by exploring the exogenous variation of family size driven by the presence of twins in the family. Using the Brazilian Census data for 1991, we nd that the exogenous increase in family size is positively related to labor force participation for boys and girls and to household chores for young women. We also and negative e ects on educational outcomes for boys and girls and negative impacts on human capital formation for young female adults. Moreover, we obtain suggestive evidence that credit and time constraints faced by poor families may explain the findings.

Market timing as a motive for IPOs: evidence from IPOs of Japanese keiretsu firms

This paper examines the relevance of market timing as a motive for initial public offerings (IPOs) by comparing IPOs of firms that are members of Japanese keiretsu industrial groups with IPOs of independent Japanese firms. We argue that Japanese keiretsu-linked IPOs form a favorable sample to find evidence of the market timing motive. Instead, the data provide strong evidence for a restructuring motive and little evidence for market timing. We find that long run returns to keiretsu and independent IPOs are not negative, contrary to U.S. evidence, and are indistinguishable from each other; initial returns to keiretsu-linked IPOs are significantly higher than to independent firms; and a significant number of keiretsu IPO firms adjust their linkages with the group following the IPO, with both increases and decreases.

Workplace diversity and incentive contracts : theory and evidence

This paper presents a simple theory of the provision of incentives in firms in which the principal optimally chooses both compensation contracts and the composition of the work force. Assuming that individuals display group loyalty, a less diverse (more homogeneous) work force will be more cooperative. Simple comparative statics provide some testable implications relating risk, diversity and incentive pay. I also analyze the case in which workers’ characteristics cannot be readily observed ex ante. The theory then predicts that firms are more likely to prevent workers from interacting with each other when workers are expected to have similar characteristics. This shows a surprising effect of diversity in the workplace: more diverse firms will promote more interactions between workers of different types, i.e. they will be less segregated. I test the main predictions of the model using a cross-sectional sample of corporate boards. I use the proportion of women on boards as a measure of diversity. There are three main empirical findings: (1) a significant negative correlation between firm risk and diversity, (2) a significant positive relationship between performance-based compensation and diversity and (3) a significant positive correlation between the number of board meetings (a measure of interactions among directors) and diversity. The evidence is broadly consistent with the implications of the theory.

Firm financial constraints and the impact of monetary policy: evidence from financial conglomerates

Building on recent evidence on the functioning of internal capital markets in financial conglomerates, this paper conducts a novel test of the balance sheet channel of monetary policy. It does so by comparing monetary policy responses of small banks that are affiliated with the same bank holding company, and this arguably face similar constraints in accessing internal/external sources of funds, but that operate in different geographical regions, and thus face different pools of borrowers. Because these subsidiaries typically concentrate their lending with small local businesses, we can use cross-sectional differences in state-level economic indicators at the time of changes of monetary policy to study whether or not the strength of borrowers' balance sheets influences the response of bank lending. We find evidence that the negative response of bank loan growth to a monetary contraction is significantly stronger when borrowers have 'weak balance sheets. Our evidence suggests that the monetary authority should consider the amplification effects that financial constraints play following changes in basic interest rates and the role of financial conglomerates in the transmission of monetary policy.
