206. Paul Krugman talks trade, industrial policy, and Trump

This episode explores the complexities of agglomeration externalities and their implications for global trade and industrial policy. Against the backdrop of Paul Krugman's pioneering research on this topic, the conversation delves into real-world examples, such as Silicon Valley and historical industrial clusters in the US, highlighting both the benefits and unforeseen risks of geographic concentration. More significantly, the discussion pivots to the recent resurgence of industrial policy, driven by national security concerns and the need for effective climate action. For instance, the CHIPS Act and Inflation Reduction Act in the US are examined as examples of this shift. Paul Krugman cautions against potential downsides, such as waste and political capture, while acknowledging the potential for strategic alliances among democratic nations to mitigate risks. Ultimately, the conversation concludes with a critical analysis of President Trump's trade policies, emphasizing the incoherence of his approach and the potential for unintended negative consequences. What this means for policymakers is a need for carefully considered industrial policies that balance strategic goals with economic realities.
