17 - Brad DeLong on Hamiltonian Political Economy and American Economic History

Episode Summary

Executive Summary: Brad DeLong traces how pragmatic, growth-oriented American economic policy gave way after 1980 to ideology, elite rent-seeking, and underperformance. He argues modern macro is dominated by monetarist instincts, yet policymakers failed after 2008 to use monetary and fiscal tools aggressively enough to restore nominal demand, leaving a still-unresolved policy mystery.

Main Topics: How DeLong got into economics (Priority: 4/5): DeLong credits exceptional teachers at Harvard and earlier math preparation for drawing him into economics and macro, emphasizing that rigorous, dynamic instruction made the field exciting and accessible. Concrete Economics and the loss of pragmatism (Priority: 5/5): DeLong and Stephen Cohen argue that pre-1980 U.S. policy was pragmatic and growth-focused, while post-1980 policy prioritized ideology, elite compensation, finance, and healthcare administration over productive investment. Hamiltonian vs. Jeffersonian political economy (Priority: 4/5): The conversation revisits the historical tension between Hamilton's developmental state and Jefferson's anti-bank, anti-city vision, using the Bank of the United States and broader American history to frame current populist debates. Populism, partisan sorting, and Brexit (Priority: 4/5): DeLong contends that modern populism is less a new phenomenon than a concentration of longstanding anti-establishment sentiment within weaker party coalitions, intensified in the U.S. by partisan realignment and in Europe by the Great Recession. The triumph of monetarism (Priority: 5/5): DeLong recounts how Keynesians increasingly adopted monetarist views on monetary policy by 2000, seeing central banks as the primary stabilization tool and fiscal policy as limited mostly to automatic stabilizers. Why macro policy failed after 2008 (Priority: 5/5): He expresses frustration that policymakers and central bankers did not use monetary and fiscal expansion more forcefully to restore nominal GDP, despite low interest rates, price rigidity, and clear arguments for stabilization.

Key Arguments: Great teachers and strong mathematical preparation were decisive in DeLong's path into economics and macro. U.S. policy before 1980 was guided by pragmatic attempts to grow the economic pie, even when politically messy or corrupt. Since 1980, the U.S. has overinvested in elite consumption, healthcare administration, and finance, sectors DeLong sees as weak contributors to broad-based growth. Historically successful U.S. development came from public-private coordination in infrastructure, railroads, land policy, and early industrial support. Jeffersonian anti-bank, anti-city ideology is contrasted with Hamiltonian development; DeLong sides strongly with the latter. Modern populism reflects the concentration of a persistent anti-establishment minority within partisan coalitions rather than a wholly new social force. Europe's political volatility is tied more to the depth of the Great Recession than to a fundamental transformation of its underlying politics. By 2000, most Keynesians had effectively become monetarists, accepting that monetary policy is the central stabilization tool. The post-2008 policy failure is puzzling because low rates, nominal rigidities, and the risk of debt-deflation should have made aggressive stabilization obvious. DeLong sees fiscal expansion, helicopter drops, and infrastructure spending as straightforward ways to restore nominal GDP, especially when borrowing costs are below nominal growth. Monetarism succeeded rhetorically because it let free-market economists treat active central bank intervention as 'neutral' rather than interventionist. After 2008, the political coalition that once defended monetarist policy against inflation fears broke down, leaving even QE to be widely viewed with suspicion.

Data Points: U.S. unemployment rate in 1982: 10.6% - Used to explain why graduate school looked safer than entering the private sector after college. American doctors vs. German doctors cost effectiveness: 30% more cost effective - Cited by DeLong from Uwe Reinhardt to argue the U.S. healthcare system wastes resources on administration rather than care. American healthcare administrators vs. German healthcare administrators: one-sixth as effective - Used to illustrate the inefficiency of U.S. healthcare administration relative to output per cost. Magnitude of anti-establishment support in U.S.: about 20% of America - DeLong relays Tyler Cowen's view that a stable minority of Americans are 'crazy' or anti-establishment. Share of Republican Party aligned with Trumpism: about 40% of the Republican Party - DeLong describes post-realignment concentration of populist sentiment within one party. Share of Republican primary electorate energized by Trumpism: about 60% - Shows how concentrated and activated the populist wing becomes in primaries. Period of partisan realignment: starting in 1964 - Goldwater-era shift that DeLong says sorted more of the populist-right into the Republican Party.

Pivotal Quotes: "back before 1980, we were self-interested, we were political, we were somewhat corrupt, but we were also pragmatic." — Brad DeLong: DeLong summarizes the core thesis of Concrete Economics about the pre-1980 policy regime. "And then around 1980, somehow we lost the narrative. And we began pulling ourselves much more toward grand theories." — Brad DeLong: Explains his critique that ideology displaced practical growth-focused policymaking. "Why helicopter drops and infrastructure investment are not obvious no-brainers across the political spectrum and also across the spectrum of economics as tools to get nominal GDP back onto its pre-2008 track remains an extraordinary mystery to me." — Brad DeLong: His closing frustration about the failure to use expansionary policy after the financial crisis.

Implications: DeLong urges a return to pragmatic, Hamiltonian policy: use government to grow output, stabilize nominal demand, and fund productive investment. For listeners, the lesson is that ideology and institutional inertia can block obviously useful macro tools.
