The capital structure of lending institutions has become an increasingly prominent issue in the world of finance. Contemporaneously, microfinance institutions (MFIs) have risen to the forefront as invaluable lending institutions in the development process. Since capital constraints have hindered the expansion of microfinance programs and microfinance organizations have had various degrees of sustainability, the question of how best to finance these organizations is a key issue. This paper explores how changes in capital structure could improve MFI efficiency and financial sustainability. I find causal evidence supporting the assertion that increased use of grants by large MFIs decreases operational self-sufficiency.

Using cross-state variation in minimum wages, we observe a positive relationship between the minimum wage and the number of alcohol-related accidents involving teen drivers. A similar effect is not observed when examining accidents among adults. The results are consistent with a positive income elasticity for alcoholic beverages and driving activities among young people, in particular for consumption out of discretionary income accorded by higher minimum wages. Evidence of a sizable impact of beer taxes on alcohol-related accidents among youths suggests that beer taxes are one avenue for policymakers to consider in counteracting this unintended consequence of minimum wages.

Since 1970, the fraction of mixed-race black-white births has increased nearly ninefold. This paper describes basic facts about the behaviors and outcomes of black-white mixed-race individuals. Unsurprisingly, on a host of background and achievement characteristics, as well as adult outcomes, mixed-race individuals fall in between whites and blacks. When it comes to engaging in risky and antisocial adolescent behavior, however, mixed-race adolescents are stark outliers compared to both blacks and whites. We argue that these behavioral patterns are most consistent with a two-sector Roy model, in which mixed-race adolescents, not having a predetermined peer group, engage in more risky behaviors in order to be accepted.
