A B S T R A C T We investigate the impact of a large negative labor market shock on short-run and long-run labor market outcomes of new entrants exposed to this shock. The shock, a labor dispute over a new collective bargaining agreement, resulted in the cancellation of the entire 2004–05 season in the National Hockey League (NHL). We compare career outcomes of new entrants exposed to this shock, players who declared for the 2004 draft, to career outcomes of new entrants in the 2003 draft who were not exposed, generating estimates of the average impact of the treatment on the treated. Results show that new entrants exposed to the shock experienced shorter careers than new entrants in the control group. The results also show strong effect heterogeneity based on observable worker characteristics. New entrants born in Europe benefited from exposure to the shock compared to new entrants born in North America, who were less likely to ever play in the NHL and had shorter careers than treated Europeans. Alternative employment opportunities in European hockey leagues represents a likely mechanism for these results.

Abstract: Road maintenance constitutes a significant component of transportation spending at all levels of government. Formulation of an efficient transportation infrastructure policy requires information about factors affecting road and traffic conditions. We generate the first causal evidence that decreasing pavement quality increases vehicle crash rates and decreases average speed. Results from parallel segment and instrumental variable models using spatially and temporally disaggregated data from Federal-Aid Highway System (FAHS) roads in California show statistically and economically significant increases in vehicle crash rates and decreases in average vehicle speed caused by road damage. These results produce a range of effect sizes that exceed those using standard road quality data. The results imply significant increases in social costs attributable to road damage.
