Matteo Maggiori (Stanford Finance Professor) on China, Geoeconomics and Exchange Rates

Quick Overview

Stanford Professor Matteo Maggiori details his research on geoeconomics, China's capital market opening as a reputation-building exercise, the resurgence of geo-economic tools like sanctions, and empirical findings showing that retail investor beliefs move significantly more than their portfolios, suggesting low flow elasticity.

Key Points: Maggiori's interest in economics stemmed from the exchange rate crises Italy faced in the 1990s, specifically mentioning the ERM crisis as a major driver. China's opening of its capital markets, particularly via the 2017 Bond Connect program, is modeled as a slow process to build reputation by enduring investor panic during crises, necessary to compete with the US as a reserve currency. Geoeconomics is defined as large countries like the US or China using existing trade and finance relationships to achieve political or economic goals abroad, exemplified by threats of losing access to the US banking system. The use of geo-economic instruments like sanctions and export controls has seen a resurgence, marking the biggest change to the world order since the Cold War. Research with Vanguard clients revealed that retail investor beliefs move a lot, but their portfolio locations show very low sensitivity to these beliefs, suggesting low flow elasticity. A key finding from investor surveys is that individual fixed effects—persistent optimism or pessimism—absorb a tremendous amount of the panel of beliefs, which is difficult to explain by observable characteristics. Maggiori developed a micro-founded general equilibrium model linking exchange rate determination to the limited risk-bearing capacity of financial intermediaries, which has been adopted by the IMF.

Context: The discussion features John Hartley interviewing Matteo Maggiori, the Hotham Family Professor of Finance at the Stanford Graduate School of Business and a senior fellow at the Hoover Institution. Maggiori recounts his journey from growing up in Rome and being influenced by Italian economic crises to working at JP Morgan and ultimately pursuing a PhD at Berkeley, guided by mentors who illuminated the research career path. The conversation centers on Maggiori's current research areas: China's international integration, the theoretical and empirical framework for geoeconomics, and empirical findings regarding investor behavior and exchange rate determination.
