In 1982, the US Congress established the Court of Appeals for the Federal Circuit (CAFC) as the sole appellate court for patent cases. Ostensibly, this court was created to eliminate inconsistencies in the application and interpretation of patent law across federal courts, and thereby mitigate...

We study when firms choose to install boards and their roles in a historical setting where neither boards nor their duties are mandated by law. Boards arise in firms with large, heterogenous shareholder bases. We propose that an important role of boards is to mediate between heterogenous...

This paper examines the potential benefits of security fungibility by conducting the first comprehensive analysis of Global bonds. Unlike other debt securities, Global bonds’ fungibility allows them to be placed simultaneously in bond markets around the world; they trade, clear and settle...

For a large sample of U.S. companies, we compare the cost of equity estimates of a two-factor international CAPM with those of the single-factor domestic CAPM and the single-factor global CAPM. Our purpose is to assess how much difference it makes for U.S. firms to use the two-factor ICAPM...

This paper argues that terrorism, beyond its immediate impact on innocent victims, also raises the costs of crime, and therefore, imposes a negative externality on potential criminals. Terrorism raises the costs of crime through two channels: (i) by increasing the presence and activity of the...

A non-trivial portion of traffic fatalities involve alcohol or illicit drugs. But does the use of alcohol and illegal substances - which is linked to depression, suicide, and criminal activity - also reduce academic performance? Recent studies suggest that drinking alcohol has a negative, if...

This paper argues that terrorism, beyond its immediate impact on innocent victims, also raises the costs of crime, and therefore, imposes a negative externality on potential criminals. Terrorism raises the costs of crime through two channels: (i) by increasing the presence and activity of the...

Criminal activity is seasonal, peaking in the summer and declining through the winter. We provide the first evidence that arrests of children and reported crimes involving children follow a different pattern: peaking during the school year and declining in the summer. We use a regression...

We use retail scanner data on purchases of high calorie food to study the link between recreational marijuana laws (RMLs) and consumption of high calorie food. To do this we exploit differences in the timing of introduction of marijuana laws among states and find that they are complements....

According to Swedish penal code, there is a "rebate" on all prison sentences before the 21st birthday. We exploit this age discontinuity to investigate how individuals respond to harsher punishments. We use a large Swedish dataset, including dates for all crimes which led to convictions for...
