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 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....

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...

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...

Raising a new-born child involves not only financial resources, but also time investment from the parents. A time constraint can affect important decisions made by parents at the early stages of an infant's life. One form of investment that is particularly important is vaccinating an infant. We...

Data from the first two waves of the Fragile Family and Child Wellbeing study indicate that infants who look like their father at birth are healthier one year later. The reason is such father-child resemblance induces a father to spend more time engaged in positive parenting. An extra day (per...

This paper examines how human capital based approaches explain the distribution of earnings. It assesses traditional, quasi-experimental, and new micro-based structural models, the latter of which gets at population heterogeneity by estimating individual-specific earnings function parameters....
