Podcast Summary: "Globalisation and Welfare" – LSE Public Lecture with Paul Krugman

Date: June 14, 2007
Speaker: Paul Krugman (Professor of Economics, Princeton University)
Host: LSE Film and Audio Team
Event: James Mead Memorial Lecture
Theme: The impact of globalization on welfare, examining theoretical promises versus real-world outcomes, challenges in distribution, and policy dilemmas.

Episode Overview

This episode features Nobel laureate Paul Krugman reflecting critically on the real-world consequences of globalization, particularly trade liberalization, for economic growth and income distribution, both in the developed and developing world. Drawing inspiration from James Mead’s foundational work, Krugman discusses how optimistic narratives about free trade have been challenged by recent decades of economic data and political realities, and explores the evolving dilemmas for policymakers.

Key Discussion Points and Insights

1. Introduction: Framing the Lecture ([00:00])

• Paul Krugman is welcomed as one of the world’s leading economists and public intellectuals.
• The talk honors James Mead, whose seminal work "Trade and Welfare" underpins modern trade theory.

2. Theoretical Case for Free Trade ([02:10])

• Krugman’s Reflection: Mead’s legacy is a "synthesis of how we think about trade and welfare."
• Free trade delivers efficiency by aligning marginal costs and prices.
  • "In a utopian world, free trade is getting you to a position of efficiency. It’s a good thing. Protectionism is a bad thing because it breaks that equality of marginal conditions." ([04:15], Krugman)
• Real-world impact of protectionism (e.g., India’s policy shift): Large but limited relative to growth outcomes.

3. Overstating the Growth Benefits of Trade Liberalization ([14:00])

• The textbook argument predicts moderate GDP bumps (~4.5% in India) from removing high tariffs, not the economic miracles some expect.
• India and Mexico as Cases:
  • India’s growth spurt occurred before major tariff cuts; relationship between openness and growth less clear-cut.
  • Mexico’s dramatic openness didn’t yield rapid catch-up with U.S. living standards.
• Notable Quote:
  • "Lesson I take from this…is that we oversold…We wanted to believe that the East Asian successes were replicable everywhere. And…trade theory says free trade is good, therefore what we think we see in the experience which says that free trade yields wonderful results is more respectable…but actually didn’t. Had nothing to do with…real trade theory." ([26:00], Krugman)

4. Globalization and Income Distribution ([32:43])

• Stolper-Samuelson Principle: Trade can worsen absolute incomes for certain labor groups, especially unskilled workers in advanced nations.
  • "People who are economists…are coming back and making the arguments that Stolper and Samuelson basically demolished 65 years ago…No, actually it doesn’t [make every group better off]." ([35:10], Krugman)
• Rising U.S. wage inequality, especially the wage premium for college-educated workers ([36:15]), tracks globalization and other forces.
  • "The median [worker’s] earnings…are down significantly, despite the fact that it’s a more productive, richer economy." ([34:15], Krugman)

5. Changing Nature and Magnitude of Trade Effects ([38:13])

• Effects once considered modest—e.g., 3–6% on wage differentials—have become more pronounced as trade with low-wage countries (esp. China) rises.
• Outsourcing and fragmentation of the value chain expand labor-intensive tradeable sectors, undermining previous limits on distributional effects ([45:30]).
  • "Textbook trade theory applied to the real-world data can easily justify a belief that international trade has widened the skill differential in the United States by 15%, maybe higher…with no obvious end in sight." ([48:30], Krugman)

6. Globalization’s Uneven Impact on Developing Countries ([49:00])

• Trade liberalization not uniformly beneficial: Gini coefficients (income inequality) have risen post-liberalization in countries like Mexico and China.
• External evidence sometimes runs contrary to expectations that trade liberalization should equalize incomes in poorer countries ([56:00]).
  • "I was quite sure that trade liberalization would equalize income in developing countries… The picture is in fact at best mixed." ([58:00], Krugman)

7. Policy Responses and Chastened Advocacy ([61:00])

• Krugman asserts that a retrenchment to protectionism is unlikely and undesirable, but acknowledges honest tradeoffs.
  • "I think a pretty open global trading system is…important…not because it’s terribly important to the economy of the United States or Western Europe…but because there are very large numbers of people who are very poor and depend desperately on…the ability to export based on really no advantage other than low wages." ([62:15], Krugman)

Policy “To-Do’s” for the Chastened Globalist:

• Honesty: Don’t oversell benefits or understate harms.
• Compensating the Losers: Rhetoric alone is insufficient; labor standards and trade adjustment assistance have limitations. Broader social insurance and more progressive tax policies are needed ([63:30]).
• Progressive Redistribution Tools: Earned Income Tax Credit (EITC)-type measures should be considered but need to be more generous and better targeted.

Memorable Moment

• "It's going to be much…harder to make this case honestly…we haven't been proved wrong, but things have turned out to be not nearly as easy, not nearly as good, not nearly as uniform in their benefits as we hoped… The world is actually not a simple place that requires just a few slogans." ([65:00], Krugman)

Selected Questions and Audience Engagement

Inequality and Global Welfare ([65:37]–[72:13])

• Danny Quah (LSE): Challenges Krugman to consider broader measures of inequality and emphasizes rapid poverty reduction in China.
  Krugman agrees on the primacy of global poverty reduction but maintains that within-country distribution is a pressing political issue in the rich world.

Immigration’s Impact ([74:36])

• Adair Turner: Asks about immigration’s contribution to inequality.
  Krugman: Immigration, especially of low-skill workers, exerts downward wage pressure, though likely less than trade. Deep splits on the issue exist across political lines.

Fair Trade & Labor Standards ([79:26])

• Query about "fair trade" as a mitigation device.
  Krugman: Supportive in principle, but cautions that such efforts can only have marginal effects given the underlying development level of poor countries.

Addressing Inequality in Developing Countries ([82:00])

• How can weak governments manage rising inequality?
  Krugman: Small interventions can help greatly, but major structural limitations persist.

Political Will and Redistribution ([83:39], [84:56])

• Questions on whether more political will or societal pressure is required to shift policy.
• Krugman: Stresses entrenched interests and the difficulty of progressive reform; sees lessons in, but also limits to, UK’s more progressive tax and benefit policies.

• "Lesson I take from this…is that we oversold…We wanted to believe that the East Asian successes were replicable everywhere." ([26:00], Krugman)
• "You can no longer credibly say, look, yes, I agree in principle, but quantitatively it’s not a big deal [distributionally]. That’s just not…now a tolerable argument." ([43:40], Krugman)
• "It’s going to be really difficult. I’m not going to be able to defend free trade with the same kind of cheerfulness… The world is actually not a simple place that requires just a few slogans." ([65:00], Krugman)

Closing Reflection

This episode offers a lucid, candid look at the evolving understanding and politics of globalization in practice. Krugman’s position evolves from unalloyed advocacy to a "chastened" defense, urging both realism about free trade’s limits and innovative redistribution at home and abroad. The exchange with a knowledgeable audience further sharpens practical and ethical dilemmas in managing globalization’s winners and losers, leaving the listener with a deeper appreciation for complexity over ideology.
