We analyze the impact of a freeway interchange collapse in the San Francisco Bay area on the difference in airfare quotes for travel into the area's main airports. The incident temporarily made Oakland airport a less attractive choice for traveling to San Francisco. Using a sample of fare quotes...

All but two professional baseball leagues have adopted the “designated hitter” (DH) rule, which allows a team’s manager to designate a player to bat at the plate and run the bases in place of another player, usually the team’s pitcher. Unlike the team’s other players, the designated...

This paper asks whether adversity spurs the introduction of process innovations and increases the use of managerial incentives by firms. Using a large panel data set of workplaces in Canada, our identification strategy relies on exogenous variation in adversity arising from increased border...

This study estimates the reform effects of a reduction in statutory sick pay levels on various outcome dimensions. A federal law reduced the legal obligation of German employers to provide 100 percent continued wages for up to six weeks per sickness episode to 80 percent. This measure increased...

In 1999, in Germany, the statutory sick pay level was increased from 80 to 100 percent of foregone earnings for sickness episodes of up to six weeks. We show that this reform has led to an increase in average absence days of about 10 percent or one additional day per employee, per year. The...

This paper uses a natural experiment approach to identify the effects of an exogenous change in future pension benefits on workers' training participation. We use unique matched survey and administrative data for male employees in the Dutch public sector who were born in 1949 or 1950. Only the...

Millions of people emigrate every year in search of better economic and social opportunities. Anecdotal evidence suggests that emigrants may have over-optimistic expectations about the incomes they can earn abroad, resulting in excessive migration pressure, and in disappointment amongst those...

Hurricanes in the Caribbean and Central America represent a natural experiment to test the intertemporal approach to current account determination. The intertemporal approach allows for the possibility of intertemporal trade, via international borrowing. Previous tests of intertemporal current...

Several studies, conducted on U.S. data, have found rather strong income responses to changes in marginal tax rates, when treating tax reforms as "natural experiments" and applying the differences-of-differences estimator on individual income data. The Norwegian tax reform of 1992 implied...

Growth studies show, counter to intuition, that the discovery of a natural resource may be a curse rather than a blessing since resource-rich countries grow slower than others. But it has been suggested that Norway may be an important exception to the curse and that the curse does not afflict...
