Using firm level data, we report a significant fall in the exchange rate exposure of emerging market firms over the past 10 years, and relate this to higher derivatives market participation. Our methodology follows a three stage approach. First, we measure and report foreign exchange exposures...

Throughout the years spanned by the U.S. Vital Statistics Linked Birth and Infant Death Data (1983-2002), birth weights are measured most precisely for children of white and highly educated mothers. As a result, less healthy children, who are more likely to be of low socioeconomic status, are...

The typical conclusion reached when researchers examine exchange rate exposure is that only a few firms are exposed. This finding is puzzling since institutional knowledge and theory suggests a larger effect. In this paper, we compare results obtained using a linear approach with those from...

We use state repeals of blood test requirements (BTRs) for a marriage license that occurred between 1980 and 2008 to examine the impact of changes in the price of marriage on the marriage decision. Using a within-group estimator that holds constant state and year effects and exploits variation...

This study demonstrates that regression discontinuity designs will arrive at biased estimates when attributes related to outcomes predict heaping in the running variable. We discuss several approaches to diagnosing and correcting for this type of problem. Our primary example focuses on the use...
