The world economy is entering a period of profound change. Trade, investment, technology and supply chains are no longer viewed solely through an economic lens; they are increasingly shaping international relations, national security and business strategy. What does this mean for governments, firms, and the next generation of economists and policymakers? In this lecture, Dennis Novy, Deputy Chief Economist at the UK Foreign, Commonwealth and Development Office and Professor of Economics at the University of Warwick, will explore how economic and geopolitical forces are becoming more closely intertwined. Drawing on cutting-edge research, he will introduce the concept of “tariff confusion”, the idea that complexity and uncertainty in trade policy can have significant economic consequences beyond the tariffs themselves. Using real-world examples from recent developments in global trade, the lecture will examine how businesses respond to policy uncertainty, why trusted economic relationships matter, and how governments are adapting to new challenges in economic security and resilience. The session will also demonstrate how academic research informs real-world policymaking, offering a unique insight into how the UK and other countries are navigating a more contested global economy while seeking to remain open, innovative and connected. Ideal for academics interested in economics, public policy, international relations, business and global affairs, this lecture provides a rare opportunity to hear from a leading economist working at the intersection of research and government. Attendees will gain practical insights into some of the most important economic and geopolitical challenges shaping the world today, and learn how economic ideas can influence decisions that affect countries, companies and citizens around the globe.
