The Age Discrimination in Employment Act of 1978 expanded employee age protections to age 70, making the widespread practice by U.S. firms of mandating retirement at age 65 illegal. Building on the work of Lazear (1979), we propose that the law change not only weakened the long-term employment...

This paper analyzes the job assignment problem faced by a firm when workers' skills are distributed along several dimensions and jobs require different skills to varying extent. I derive optimal assignment rules with and without slot constraints, and show that under certain circumstances workers...

This paper provides the first analysis of the trade-off between convenient flight connections and airport congestion. A continuous spatial model illustrates this trade-off in a framework where a small gap between flight operating times raises congestion while also shortening a connecting...
