We conduct a theory-based empirical study of intraindustry trade in homogen
eous products. We derive an oligopolistic model of intra-industry trade, wh
ich is an extension of the segmented market model of trade, initially propo
sed by [Brander, J. A., 1981, Intra-industry trade in identical commodities
, Journal of International Economics 11, 1-14]. The empirical implementatio
ns of the model are investigated in the contest of the petrochemical indust
ry. Our analysis employs a unique data set containing detailed product- and
location-specific data on the petrochemical industries in German!: and the
United States. Allowing for different empirical specifications, we find th
at cross-product variations in bilateral intra-industry trade of petrochemi
cals are well explained by the variables suggested by the theoretical model
