This article revisits a classical theme in economics, that is, the relationship between trade protection and economic performance, with an improved treatment of the endogeneity of tariffs and with consideration of alternative performance criteria. This paper also considers the effects of asymmetric protection, such as higher tariffs on consumer goods and lower tariffs on producer goods. Using sectoral data on Korean manufacturing during the period from 1967 to 1993, this study finds that the effect of trade protection by tariff tends to show up not in terms of total factor productivity but in terms of revealed comparative advantage and export shares of sectors. Such an effect tends to be greater in consumer goods, which are the main targets of promotion by higher tariffs. This study verifies the potentially positive role of tariffs under certain conditions, especially under discipline from world markets.
