The infant industry argument based on this type of learning externality was first explicitly modeled in a dynamic framework by Bardhan (1971). His single-industry model has since been extended to analyze the consequences of learning in more than one industry. Clemhout and Wan (1970) study infant industry protection policies for a group of
