Bullying is a behavioral phenomenon that has received increasing attention in recent times. This paper uses a structural model with latent skills and longitudinal information from Korean youths to identify the determinants and effects of bullying. We find that, unlike cognitive skills,...

This paper compares the economic questions addressed by instrumental variables estimators with those addressed by structural approaches. We discuss Marschak's Maxim: estimators should be selected on the basis of their ability to answer well-posed economic problems with minimal assumptions. A key...

This paper examines the properties of instrumental variables (IV) applied to models with essential heterogeneity, that is, models where responses to interventions are heterogeneous and agents adopt treatments (participate in programs) with at least partial knowledge of their idiosyncratic...

This paper establishes that a low dimensional vector of cognitive and noncognitive skills explains a variety of labor market and behavioral outcomes. For many dimensions of social performance cognitive and noncognitive skills are equally important. Our analysis addresses the problems of...

This paper investigates whether centralized admissions systems can alter school segregation. We take advantage of the largest school-admission reform implemented to date: Chile's SAS, which in 2016 replaced the country's decentralized system with a Deferred Acceptance algorithm. We exploit its...

Higher education in Latin America and the Caribbean has expanded dramatically in the past 15 years, as the average gross enrollment rate has more than doubled, and many new institutions and programs have been opened. Although higher education access has become more equitable, and higher...

Bullying cannot be tolerated as a normal social behavior portraying a child's life. This paper quantifies its negative consequences allowing for the possibility that victims and nonvictims differ in unobservable characteristics. To this end, we introduce a factor analytic model for identifying...
