Abstract

This dissertation investigates the relationship between industry concentration and export intensity for the entire American manufacturing sector in 1982 and for durable and non-durable goods industries. Export intensity is defined as value of exports divided by value of shipments. The effects of agglomeration and transportability on export intensity are examined through the use of a geographic concentration index. The model consists of a three-equation framework which also allows for the simultaneous determination of industry concentration and the tariff rate.;The major conclusion is that there is a positive and significant effect of industry concentration on export intensity both for the entire manufacturing sector and its two subsets. A non-linear specification of the four-firm concentration ratio as a measure of concentration showed that the industry concentration/export share relationship has an inverted "U" shape. This was true both for all industries and durable and non-durable goods industries. In all three cases, export share peaked at a concentration ratio in the 64%-70% range. In each case, around 11% of the observations were to the right of the peak.;The non-linear specification of the industry concentration/export share relationship was also tested using the Herfindahl-Hirschman index (H) as a measure of concentration. The inverted "U" relationship was still observed but was weaker on account of a small cluster of very high H observations which, when removed, resulted in the weakening of the relationship.;Tariff/industry concentration and industry concentration/geographic concentration interactions were also used in the export intensity equation. The first interaction was designed to test whether the positive effect of industry concentration on export share is reinforced through protection. This interaction was negative and significant for all industries and durable goods industries. It was positive and weakly significant for non-durable goods industries. The industry concentration/geographic concentration interaction was negative and significant for the entire manufacturing sector and its subsets, suggesting that the positive effects of industry concentration and agglomeration do not reinforce each other. Finally, average elasticities of export share with respect to concentration were calculated and were all well below one.
