there is enough cross-sectional variation of the observed states.

We describe identification conditions for dynamic discrete choice models that include unobserved state variables that are correlated across individuals and across time periods. The proposed framework extends the standard literature on the structural estimation of dynamic models by incorporating...

The estimation of production functions suffers from an unresolved identification problem caused by flexible inputs, such as intermediate inputs. We develop an identification strategy for production functions based on a transformation of the firm's short-run first order condition that solves the...

The panel data literature on deterrence and capital punishment contains a wide range of empirical claims despite the use of common data sets for analysis. We interpret the diversity of findings in the literature in terms of differences in statistical model assumptions. Rather than attempt to...

We present a new approach to the estimation of production functions that allows for richer patterns of firm heterogeneity than can be accommodated under the proxy variable methods of and Olley/Pakes and Levinsohn/Petrin. In particular, we show that the economics of the firms static input choice...

We estimate a dynamic model of default for a cohort of Colombian debtors between 1997 and 2004, which was a period of unprecedented financial stress in Colombia. We develop a methodological framework based on a fully dynamic behavioral model that accounts for both cross-sectional and aggregate...

This paper considers the problem of inference about the effect of a program on multiple outcomes when assignment of treatment status is imperfectly randomized. Here, by imperfect randomization we mean that treatment status may have been reassigned after the initial randomization on the basis of...

This paper formulates and estimates a model of the evolution of child cognitive and noncognitive skills as determined by parental investments at different stages of the life cycle. We estimate the elasticity of substitution between contemporaneous investments and inherited stocks of skills to...

In this paper we build on the Cunha, Heckman and Navarro (2005) and show that labor earnings risk has increased considerably over time and it has increased more for lower skill groups than higher skill groups

his paper presents formal models of child development that capture the essence of recent findings from the empirical literature on child development. The goal is to provide theoretical frameworks for interpreting the evidence from a vast empirical literature, for guiding the next generation of...
