NBER Spring 2005 Reporter Summary

Core Content

The NBER Reporter for Spring 2005 provides an overview of the research conducted by the International Trade and Investment (ITI) Program, highlighting key areas of study, theoretical models, and empirical findings. The report also includes information about NBER's structure, its funding sources, and related policy discussions.

Main Research Topics

1. Microeconomics of the Trading Firm

• Firm Heterogeneity: Firms differ in productivity, and only the most productive ones become exporters. This is modeled using Ricardian and Melitz frameworks.
• Key Models:
  • Ricardian Model: Firms compete in domestic markets, with only the most productive surviving.
  • Melitz Model: Firms face fixed costs of production and exporting. Only the most productive firms can afford to export.
• Empirical Applications:
  • Studies on U.S. and French firms show that productivity growth is faster in industries with falling trade costs.
  • Export variety contributes to productivity growth within countries.
  • Import price indices may overstate the benefits of trade due to ignoring product variety.

2. Incomplete Contracts and Outsourcing

• Antras' Work: Models incomplete contracts between firms and subsidiaries, explaining the shift of production to lower-cost regions.
• Outsourcing Models:
  • Grossman and Helpman develop general equilibrium models of outsourcing, considering production in different locations.
  • Yeaple and Nocke explore complex integration strategies, assuming firms differ in international mobility.
• FDI Determinants:
  • Firms with higher productivity are more likely to engage in FDI.
  • Capital-intensive industries are more likely to use intra-firm trade.
  • Ownership structures (e.g., partial vs. complete foreign ownership) are influenced by coordination costs and tax policies.

3. Political Economy of Trade Policy

• Trade Reform Alternatives:
  • Unilateral, bilateral, and multilateral reforms are compared.
  • Unilateral reform can lead to changes in voter incentives and reduce protectionist equilibria.
  • Majority voting often leads to protectionist outcomes due to conflicting ex ante and ex post objectives.
• Bilateral vs. Multilateral Reform:
  • Sequential bargaining vs. simultaneous bargaining models are used to analyze trade agreements.
  • Preferential trade agreements can either facilitate or hinder global free trade, depending on context.
• GATT/WTO Provisions:
  • The Most-Favored-Nation (MFN) principle and the escape clause are examined.
  • Bagwell and Staiger argue that MFN can reduce early concession willingness but can be mitigated through renegotiation and reciprocity.
  • The WTO's subsidy rules may have unintended consequences on the multilateral trading system.

4. Tariffs, Subsidies, and Dumping

• Escape Clause: U.S. application of the escape clause under Section 201 is analyzed, showing potential conflicts with WTO procedures.
• Export Subsidies: The impact of export subsidies on the aircraft industry is studied, showing how they affect market shares and prices.
• Anti-Dumping Actions: U.S. and global use of anti-dumping provisions is examined, noting that experience with these actions reduces dumping margins and increases filing activity.

5. Trade and Developing Countries

• Globalization and Poverty: A conference on this topic explores the effects of trade on poverty in developing countries.
• Trade and the Environment:
  • Lower-income countries are not significant pollution havens.
  • Foreign plants in developing countries are more energy-efficient and cleaner than domestic ones.
  • Trade can have mixed effects on the environment, depending on the measure (e.g., pollution, regulation, resource sustainability).
• Openness and Growth:
  • Trade openness is linked to economic growth, with studies controlling for democracy, income, and institutions.
  • Trade can improve environmental regulation but may not affect all types of emissions equally.

Key Information

• NBER Overview:
  • Founded in 1920, it is a private, nonprofit research organization focused on quantitative analysis of the American economy.
  • Funding comes from individuals, corporations, and private foundations.
  • The ITI Program is directed by Robert C. Feenstra.
• New Data Service:
  • NBER offers a free email service for U.S. government data releases.
• Important Researchers:
  • Jonathan Eaton, Samuel Kortum, Marc Melitz, Pol Antras, and others are highlighted for their contributions.
• Policy Impacts:
  • Studies on FDI, tariffs, subsidies, and trade agreements provide insights into their effects on productivity, wages, and trade flows.
  • The political economy of trade policy is explored through models and empirical analyses.

Conclusion

The ITI Program continues to advance understanding of international trade and investment through both theoretical and empirical research. The focus on firm heterogeneity, incomplete contracts, and the political economy of trade policy provides valuable insights into how trade affects economies, industries, and countries. The findings have implications for trade policy, economic development, and environmental outcomes.
