Key Figures

Internalization and Gravity era

Rüdiger Dornbusch [1] is prominent in this era with affiliations such as Massachusetts Institute of Technology [3] and Tufts University [4], reflecting his role across major institutions of the time. His key contributions, notably in the paper 'Expectations and Exchange Rate Dynamics' [7], advanced the overshooting framework for exchange rates, linking asset-market expectations to rapid short-run currency adjustments and clarifying why monetary news can cause larger moves than fundamentals. Kenneth Rogoff [2] is likewise anchored in this era through positions at Harvard University [5] and the University of California, Berkeley [6], illustrating his placement within leading institutions. His contribution in 'Empirical exchange rate models of the seventies' [8] systematically evaluated competing empirical models of exchange rate dynamics, informing the gravity-like understanding of international price movements and investment flows that characterized the era.

Global Production Integration era

Jong‑Wha Lee[1] with affiliations at Cornell University[3] and Seoul National University[4] was a central figure in international economics during the Global Production Integration era. His 1998 paper How does foreign direct investment affect economic growth?[7] contributed to the era by clarifying how FDI can influence growth through productivity channels and technology diffusion, underscoring the era's emphasis on cross-border investment and networked production. John H. Dunning[2], with Rutgers, The State University of New Jersey[5] and the University of Oslo[6], was a foundational figure in this era. His 1995 book Multinational Enterprises and the Global Economy.[8] shaped the understanding of how multinational enterprises drive cross-border production and technology diffusion, informing empirical methods and policy debates of the era.

Energy-Driven Macrofinance era

Philip R. Lane[1], affiliated with Princeton University[3] and the National University of Singapore[4], stands out in the Energy-Driven Macrofinance era (2007–2023). His key contribution in this era is the paper The external wealth of nations mark II: Revised and extended estimates of foreign assets and liabilities, 1970–2004[7], which revises cross-border wealth measures and informs how external financial positions shape macrofinancial spillovers. Gian Maria Milesi-Ferretti[2], affiliated with Trinity College Dublin[5] and Marymount University[6], is a central figure in cross-border wealth research within the era. His work on the same paper[7] provides the dataset and method for tracking foreign assets and liabilities, underlining external wealth dynamics as a key channel for energy-driven spillovers and policy transmission.
