| Tiivistelmä: | The authors evaluate two alternative models of international trade in differentiated products. An increasing returns model where varieties are linked to firms predicts home market effects: increases in a country's share of demand cause disproportionate increases in its share of output. In contrast, a constant returns model with national product differentiation predicts a less than proportionate increase. The authors examine a panel of U.S. and Canadian manufacturing industries to test the models. Although the authors find support for either model, depending on whether the authors estimate based on within or between variation, the preponderance of the evidence supports national product differentiation. |
