In this paper, we investigate two questions. First, we explore which entity (the NHTSA or the manufacturer) is more likely to initiate a given auto safety recall campaign. Second, we analyze the determinants of owner response rates to safety recalls. Our data spans nineteen years (1980–1998) for the six largest auto manufacturers. We find evidence that the government initiates larger, less hazardous recalls involving older models and financially weak firms. Inexpensive recalls are more likely to be manufacturer initiated. The largest owner repair responses are associated with newsworthy hazardous defects of new domestic vehicles in their inaugural model year.
