This study pairs variation stemming from volcanic eruptions from Kilauea with the census of Hawai'i's public schools student test scores to estimate the impact of particulates and sulfur dioxide on student performance. We leverage spatial correlations in pollution in conjunction with proximity...

This paper examines whether and to what extent changes in beliefs about own HIV status induce changes in risky sexual behavior using data from married males living in three regions of Malawi. Risky behavior is measured as the propensity to engage in extramarital affairs. The empirical analysis...

We test implications of a simple equilibrium model of informality using a survey of 48,000 small firms in Brazil. In the model, agent's ability to manage production differ and informal firms face a higher cost of capital and limitation on size, although these informal firms avoid tax payments....

This paper investigates determinants of informal economic activity. We present an equilibrium model of informality and test its implications using a survey of 48,000 small firms in Brazil. We define informality as tax avoidance; firms in the informal sector avoid tax payments but suffer other...

This paper studies the identification of a simultaneous equation model involving duration measures. It proposes a game theoretic model in which durations are determined by strategic agents. In the absence of strategic motives, the model delivers a version of the generalized accelerated failure...

This paper investigates the evolution of socio-emotional skills over the life cycle and across generations. We start by characterising the evolution of these skills in the first part of the life cycle. We then examine whether parents’ socio-emotional skills in early childhood rather than in...

Many HIV testing programs in Africa and elsewhere aim to reduce risk-taking behaviors by providing individuals with information about their own HIV status. This paper examines how beliefs about own HIV status affect risky sexual behavior using data from married couples living in three regions of...
