T.W. Schultz (1975) proposed that returns to human capital were highest in economicenvironments where technology, price or production shocks were common and managerial skillsto adapt resource allocations to those shocks were most in need. We hypothesize that variationin returns to human capital...

Sometimes authorities are unable to identify rapidly the origin of a tainted product.In such cases, recalls or warnings often apply to all suppliers, even to those thathad not contributed to the contamination. Traceability enables more targetedrecalls by identifying more specically the product's...

This paper studies the dynamic sorting of workers prior to labor market entry that leads to skill differences across cities of different sizes, as well as its consequences on the estimation of agglomeration effects. Using rich administrative data for young, college-educated workers in Colombia,...

Estimation in models with endogeneity concerns typically begins by searching for instruments. This search is inherently subjective and identification is generally achieved upon imposing the researcher's strong prior belief that such variables have no conditional impacts on the outcome. Results...

Random Utility Maximization (RUM) models of recreation demand are typically plaguedby limited information on environmental and other attributes characterizing the available sitesin the choice set. To the extent that these unobserved site attributes are correlated with theobserved characteristics...

We describe a simulation-based algorithm for Bayesian estimation of structuraleffects in models where the outcome of interest and an endogenous treatment variableare ordered. Our algorithm makes use of a reparameterization, suggested by Nandramand Chen (1996) and Li and Tobias (2005) in the...
