Trade Liberalization and Economic Growth

Résumé du livre

There has been a long-held belief that there is an association between economic growth and increased levels of international trade. However, more recent work has questioned this hypothesis and the re-opening of the debate has identified two key areas of contention. One is the extent to which the effects of openness are conditional on factors omitted from the core regression relationship and hence how the hypothesis is tested. The other is the meaning and measurement of openness and liberalization. This paper addresses both these areas by exploring the nature of heterogeneity in growth performance among liberalizing countries using a difference-in-difference approach. The results show that, while in aggregate there appears to be a positive but small impact of trade liberalization on growth, this masks a huge range of responses. Empirical analysis of this heterogeneity shows that a one-size-fits-all policy is not necessarily the most effective, and suggests a case-by-case approach is more appropriate.
