We assess whether the COVID-19 vaccine induces COVID-19 risky behavior (e.g., going to bars and restaurants) and thus reduces vaccine efficacy. A key empirical challenge is the endogeneity bias when comparing risk-taking by vaccination status since people choose whether to get vaccinated. To...

Exogenous shocks often impact a local labor market more than at the national level. This study improves upon the standard Difference in Difference (DD) approach by examining exogenous shocks using a Generalized Difference in Difference (GDD) econometric approach that identifies the effects of...

This paper shows that the opportunity costs resulting from economic interdependence decrease the equilibrium probability of war in an incomplete information game. This result is strongly consistent with existing empirical analyses of the inverse trade-conflict relationship, but is the opposite...

This paper examines the interactive effect of distance and trade on international conflict and cooperation. The effect of geographic distance depends on trade, while the effect of trade varies with geographic distance. Trade reduces conflict to a greater extent when dyads are geographically...

At least since 1750 when Baron de Montesquieu declared "peace is the natural effect of trade," a number of economists and political scientists espoused the notion that trade among nations leads to peace. Employing resources wisely to produce one commodity rather than employing them inefficiently...

Current empirical growth models limit the determinants of country growth to geographic, economic, and institutional variables. This study draws on conflict variables from the Correlates of War (COW) project to ask a critical question: How do different types of conflict affect country growth...

In 1958 Jacob Mincer pioneered an important approach to understand how earnings are distributed across the population. In the years since Mincer's seminal work, he as well as his students and colleagues extended the original human capital model, reaching important conclusions about a whole array...

This paper relaxes the assumption of homogeneous rates of return to schooling by employing nonparametric kernel regression. This approach allows us to examine the differences in rates of return to education both across and within groups. Similar to previous studies we find that on average blacks...

This study utilizes a panel fixed effects model to explore the economic impact of hurricanes on local crop production in Jamaica using quarterly 1999-2008 micro level data. We find, in general, that hurricanes will have a negative impact on production but not for crops grown below ground. The...
