Ernest Liu

Ernest Liu is an Assistant Professor of Economics at Princeton University, with research interests in production networks, growth, international trade, and finance. His work includes developing sufficient statistics for how one country’s income and welfare respond to foreign countries’ TFP growth through trade linkages, and showing that as countries become greater friends in terms of welfare exposure, they become greater political friends in terms of United Nations voting and strategic rivalries; understanding why low interest rates give rise to persistent market power and low productivity growth; analyzing industrial policies in production networks and showing why promoting upstream sectors may results in aggregate gains in production efficiency. He received his Bachelor’s degree from Carleton College in 2010 and Ph.D. from MIT in 2017.
