We propose a complementary explanation for the evolution of the college gender gap that emphasizes the raising opportunity cost of pursuing a college degree for men, due to the increase in the rewards to becoming a superstar in men-dominated occupations, like professional sports. We support our...

I present a survey on the econometric approach to the measurement of efficiency, focusing on the models used in empirical applications. I describe both models for cross sectional data and models for panel data. Finally, I survey the recent literature on models with time varying technical efficiency.

We report that on any given day the number of inmates released from incarceration significantly affects the number of offenses committed this day, and we name this as first-day recidivism. Our estimates of this novel approach to study early recidivism are robust to a variety of alternative model...

This paper explores the determinants of firm survival in export markets. Our theoretical framework includes a geometric Brownian motion for firm profitability, market-specific sunk and fixed exporting costs that are common across firms, and firm- and market-specific profitability shifters that...

In this paper I provide an estimate of labor productivity growth for the electricity distribution sector in Latin America, in the period 1994 to 2001. I report an annual rate of labor productivity change of about 6%. A comparison of the changes in prices and labor productivity reveals that, in...

This paper addresses an important source of variation within democracies – the degree of institutionalization. The concept of institutionalization describes the extent to which politics takes place, and is believed to take place, via formal political institutions. Countries vary in their...

This paper empirically investigates whether changes in product market competition affect firm boundaries. Exploiting regulation-induced shocks to entry barriers and differences in regulation enforcement across cities to obtain exogenous variation in competition, we establish a negative causal...

I explore the causes of the existence of political dynasties in democratic societies. In particular, I investigate the causal relationship between tenure length and posterior dynastic success. Since tenure length is potentially endogenous in a model of political dynasties, I exploit a natural...

This paper is concerned with the characteristics, determinants and consequences of varying levels of congressional institutionalization. Our work can be traced back to the early work on congressional institutionalization done by Polsby (1968), which is complemented here by the game-theoretic...
