We investigate the relationship between participation in physical activity and self reported happiness in the United States. IV estimates based on data from the Behavioral Risk Factor Surveillance System between 2005 and 2009 and County Business Patterns indicate that individuals living in a...

I investigate the impact of unemployment on crime using a country-level panel data set from Europe that contains consistently measured crime statistics. Unemployment has a positive influence on property crimes. Using earthquakes, industrial accidents and the exchange rate movements as...

We show that part of the international variation in employment laws is due to different beliefs about the impact of hard work as opposed to luck and connections on success. In societies where a greater proportion of people relate their life prospects to chance and connections, stronger...

We propose a kernel-based estimator for a partially linear model in triangular systems where endogenous variables appear both in the nonparametric and linear component functions. Our estimator is easy to implement, has an explicit algebraic structure, and exhibits good finite sample performance...

We introduce a generalization of the approximate factor model that divides the observable variables into groups, allows for arbitrarily strong cross-correlation between the disturbance terms of variables that belong to the same group, and for weak correlation between the disturbances of...

We study the scope of local indirect least squares (LILS) methods for nonparametrically estimating average marginal effects of an endogenous cause X on a response Y in triangular structural systems that need not exhibit linearity, separability, or monotonicity in scalar unobservables. One main...
