 abstract = {This paper looks for dynamic patterns in international trade flows using comprehensive multilateral American and Japanese data disaggregated to the four-digit SITC level. Little evidence is found of product-cycle dynamics between 1962 and 1988. Rather, goods that begin the sample in surplus (deficit) almost always remain in surplus (deficit) throughout the sample.},
