The paper by Sebastian Edwards, "Openness, Trade Liberalization, and Growth in Developing Countries," published in the *Journal of Economic Literature* in September 1993, reviews the literature on the relationship between trade policy, openness, and economic growth in developing countries. The author discusses the historical shift from protectionist policies to more open and outward-oriented economies, driven by academic research and policy changes. Key points include: 1. **Protectionist Policies and Import Substitution Industrialization (ISI)**: In the 20th century, many developing countries adopted protectionist policies, such as ISI, based on the belief that industrialization was necessary to reduce the gap between rich and poor countries. However, these policies often led to reduced incentives for agriculture and exports. 2. **Empirical Evidence on Trade Liberalization**: Studies using historical and statistical methods found that more open and outward-oriented economies outperformed those with restrictive trade regimes. This evidence supported the argument for freer trade and market-oriented reforms. 3. **Debt Crisis and Policy Shifts**: The 1982 debt crisis and the poor performance of Latin American countries under ISI policies contrasted sharply with the rapid growth of East Asian countries, which had implemented outward-oriented strategies. This shift in public opinion led to increased support for trade liberalization among policymakers. 4. **Economic Models and Theories**: The paper reviews modern empirical work on trade policy and growth, including large-scale multi-country studies and econometric analyses. These studies often used indices like effective rates of protection (ERPs) and effective exchange rates (EREs) to measure trade orientation and liberalization. 5. **Devaluations and Trade Liberalization**: Devaluations were found to be an important component of liberalization policies, as they reduced the anti-export bias and encouraged exports. However, the effectiveness of devaluations varied, and their impact on economic performance was not always positive. 6. **Cross-Country Evidence**: Empirical evidence from multi-country studies generally supported the hypothesis that more liberalized trade regimes led to higher export growth and, indirectly, to higher GDP growth. However, the direct effect of liberalization on growth was less clear. 7. **Controversies and Future Directions**: The paper concludes by discussing ongoing controversies and future research directions, emphasizing the need for more precise definitions and measurements of trade regimes and their impact on economic growth. Overall, the paper provides a comprehensive review of the literature on trade policy and growth in developing countries, highlighting the importance of openness and trade liberalization in fostering economic development.The paper by Sebastian Edwards, "Openness, Trade Liberalization, and Growth in Developing Countries," published in the *Journal of Economic Literature* in September 1993, reviews the literature on the relationship between trade policy, openness, and economic growth in developing countries.
