Using detailed data on trade and tariffs from 1992–2007, the chapter examines how the Association of Southeast Asian Nations (ASEAN) Free Trade Agreement has affected trade with nonmembers and external tariffs facing nonmembers. First, the chapter examines the effect of preferential and external tariff reduction on import growth from ASEAN insiders and outsiders across HS 6-digit industries. It finds no evidence that preferential liberalization has led to lower import growth from nonmembers. Second, the chapter examines the relationship between preferential tariff reduction and most-favored-nation (MFN) tariff reduction. It finds that preferential liberalization tends to precede external tariff liberalization. To examine whether this tariff complementarity is a result of simultaneous decision-making, it uses the scheduled future preferential tariff reductions (agreed to in 1992) as instruments for actual preferential tariff changes after the Asia crisis. The results remain unchanged, suggesting that there is a causal relationship between preferential and MFN tariff reduction. The chapter also finds that external liberalization was relatively sharper in the products where preferences are likely to be most damaging, providing further support for a causal effect. Overall, the results imply that the ASEAN agreement has been a force for broader liberalization.
