Episode 025: Conversation with John Cochrane

Introduction
In this episode of Thematic Edge, Marvin Barth and Mark Farrington are joined by John Cochrane, Senior Fellow at the Hoover Institution, former Professor of Finance at the University of Chicago Booth School of Business and author of The Fiscal Theory of the Price Level.
One of the most influential voices in modern financial economics, Cochrane brings his trademark intellectual curiosity and willingness to challenge conventional thinking to a wide-ranging discussion of economic models, inflation, fiscal policy and central banking.
The conversation explores why sophisticated economic models can fail to capture economic reality, how government debt and fiscal credibility influence inflation and exchange rates, and what Switzerland’s remarkably strong currency reveals about the relationship between fiscal discipline and monetary stability.
The discussion also examines Japan’s response to supply shocks, the reliability of inflation measures and whether central banks have misunderstood the role of expectations. Ultimately, it raises a fundamental question: can central banks deliver price stability without the support of responsible fiscal policy?
Key themes
* Economics beyond conventional boundaries: Cochrane reflects on his career spanning finance and macroeconomics, the growing specialisation of academic research and the contributions of 2026 Nobel laureates Robert Hall and Michael Woodford.
* Economic models and their limitations: Marvin challenges the Federal Reserve’s persistent underestimation of US potential growth, while Cochrane argues that models are most useful as ‘quantitative parables’ rather than forecasting machines.
* The fiscal theory of the price level: Cochrane explains how confidence in a government’s ability to honour its debt influences inflation, providing an alternative perspective to conventional monetary explanations.
* The Swiss franc and fiscal credibility: Switzerland’s fiscal discipline offers a compelling explanation for the franc’s sustained strength, illustrating how fiscal policy influences exchange rates and sovereign borrowing costs.
* Japan’s response to supply shocks: Mark explores Japan’s use of subsidies to cushion rising energy and food costs, prompting a debate over the economic consequences of suppressing market price signals.
* Measuring inflation: From headline and core inflation to trimmed means, the discussion examines whether central banks’ preferred measures provide better guidance or obscure persistent inflationary pressures.
* Inflation expectations and credibility: Marvin and Cochrane explore the distinction between financial market expectations and those of consumers, questioning whether central bank communication can substitute for credible policy action.
* The Fed’s mandate and fiscal responsibility: The discussion concludes by questioning what price stability should mean, whether Congress should provide clearer direction and why monetary policy alone cannot guarantee low inflation.
