This article provides a selective review on the recent literature on econometric models of network formation. The survey starts with a brief exposition on basic concepts and tools for the statistical description of networks. I then offer a review of dyadic models, focussing on statistical models...

This paper studies the nonparametric identification and estimation of voters' preferences when voters are ideological. We build on the methods introduced by Degan and Merlo (2009) representing elections as Voronoi tessellations of the ideological space. We exploit the properties of this...

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 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...

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...

Social interactions determine many economic behaviors, but information on social ties does not exist in most publicly available and widely used datasets. We present results on the identification of social networks from observational panel data that contains no information on social ties between...

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 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...
