Estimation of world trade for used automobiles

Abstract

In order to provide the basic information for building an international automobile recycling system, this article attempts to estimate the multilateral trade for used automobiles. First, the problems in evaluation of the used automobile trade were clarified through the trade data obtained from the United Nations database (UN-DB) and the Global Trade Information Services database (GTI-DB). Furthermore, we developed an estimation method for the used automobile trade using the highlighted advantages of the UN-DB and GTI-DB. The reasons for employing this estimation method were to correct the systematic errors in both databases and to sample used automobile data from the UN-DB by using the new and used automobile information in the GTI-DB. The world trade volume for used passenger cars in 2005 was estimated by the method developed. These results indicated that total trade volume was 5.65 × 106 vehicles, and that the exports from Germany, the United States, and Japan comprise 22%, 21%, and 20% of the global total, respectively. Moreover, the results indicate that these countries export used passenger cars not only to developing countries (54%), but also to developed countries (46%).
