Abstract

During the recent economic crisis, many countries have adopted stimulus programs designed to achieve two goals: to stimulate economic activity in lagging durable goods sectors and to protect or even enhance environmental quality. The environmental benefits are often viewed and much advocated as co-benefits of economic stimulus. This paper investigates the potential trade-o_ between the stimulus and environmental objectives in the context of the popular U.S. Cash-for-Clunkers (CFC) program by developing and estimating a dynamic discrete choice model of vehicle ownership. Results from counterfactual analysis based on several specifications all show that the design elements to achieve environmental bene_ts significantly limit the program impact on demand stimulus: the cost of vehicle demand stimulus after netting out environmental benefits can be up to 77 percent higher under the program than that from an alternative policy design without the design elements aimed at the environmental objective.
