摘要：This paper examines tariff liberalization within an environment of heterogeneous demand elasticities. Varieties produced at a lower cost (a) are imported at lower absolute demand elasticities and (b) earn higher revenues. By virtue of larger demand elasticities, low revenue varieties benefit the most from tariff liberalization. Further, if varieties are substitutable, low revenue varieties benefit at the expense of high revenue varieties. These predictions are confirmed using a case study of U...

We also briefly dis...

摘要：A major role for per-capita income in international trade, as opposed to simply country size, was persuasively advanced by many early economists including Linder (1961), Kuznets (1966), and Chenery and Syrquin (1975). Yet this crucial element of their story was abandon by most later trade economists in favor of the analytically-tractable but counter-empirical assumption that all countries share identical and homothetic preferences. This paper presents a set of assumptions which produces multip...
