    Abstract

    About 2.6 million noncompliant vehicles were removed from designated metropolitan areas in Japan after the introduction of vehicle registration restrictions under the 1992 Automobile NOx Control Law. Based on a difference-in-differences framework and using a monitor-level panel dataset for the period January 1981-December 2015, we find that the intervention led to a 3%-6% reduction in the monthly mean ambient concentration of nitrogen dioxide (NO2) in the treated areas. Back-of-the-envelope calculations identify benefits equal to about US$104 million as a result of reduced mortality from asthma. (JEL Q53, Q58).
