Identification of Barriers in International Trade under Imperfect Competition
Abstract: The paper provides a means of estimating, with a given
parameter of conjectural variation, international trade barriers under
imperfect competition from data on market shares of different countries and
producers in various markets, number of exporting firms and elasticities of
demand. The method circumvents explicit specification of the production
cost function. Both the cases of a homogeneous good and an industry with
firms producing imperfect substitutes for each other are considered.
Numerical illustrations on the barrier estimates between the EC and EFTA
are also carried out.
