This paper examines the long-term health impact of Agent Orange, a toxic military herbicide containing dioxin that was used extensively during the U.S.-Vietnam war in the 1960-70s. Using a nationally representative health survey and an instrumental variable approach that addresses the potential...

Some interventions or population attributes negate the effects of a treatment. This paper shows that incorporating these, what we call antidotal variables (AV), into a causal treatment effects analysis can with one cross-sectional regression identify the true causal effect, in addition to...

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...

This paper extends the analysis of the conflict-trade relationship by introducing foreign direct investment (FDI). We present a formal model that shows why FDI can improve international relations. We then proceed to test the model empirically. Our empirical results show that foreign direct...

This study examines whether hurricanes have any impact on performance in standardized examinations. The analysis uses a panel of thirteen Caribbean countries and over 800 schools for the period 1993 through 2010. In particular, the effect on subjects in the humanities and sciences are examined....

The gender wage gap varies across countries. For example, among OECD nations women in Australia, Belgium, Italy and Sweden earn 80% as much as males, whereas in Austria, Canada and Japan women earn about 60%. Current studies examining cross-country differences focus on the impact of labor market...

We derive a non-standard unit root serial correlation formulation for intertemporal adjustments in the labor force participation rate. This leads to a tractable three-error component model, which in contrast to other models embeds heterogeneity into the error structure. Unlike in the typical iid...

The "joint costs" model states that the incentive to strike is inversely related to the total costs associated with workers' and firms' strike activities. Not only has this model been tested with mixed results, but also the joint costs model is problematic in explaining several stylized facts in...

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...
