Abstract

We applied Smeed’s law to Japanese prefectural data. We found that while the coefficient for the number of vehicles was stable throughout the estimation period, the constant term gradually decreased. We then decomposed fatalities per capita into fatalities per accident and accidents per capita, and applied regression analysis to the data. We found the following. First, the relationship between fatalities per capita and the number of registered vehicles per capita was stable. Second, the effects of technological advances have changed the estimated coefficients for the time dummies. Finally, the role of hospitals may be difficult to incorporate into Smeed’s law.
