Interest rates and exchange rates when the money supply goes up

Saleem Bahaj, Ricardo Reis, May 21, 2025

The power of monetary policy to affect interest rates and exchange rates depends on the downward slope of the demand function. This column uses the Chinese experiment with parallel currencies to study the impact of sudden increases in money supply. The authors find causal evidence that increases in money supply lead to currency depreciations, and use this to quantify the interest elasticity of reserve demand. The results can be used to understand how the People’s Bank of China maintained the peg between the mainland and parallel currencies.

Returnees and Innovation: Evidence from Chinese Publicly Listed Firms

Yibo Qiao, Andrea Ascani, Stefano Breschi, Andrea Morrison, May 28, 2025

We investigate the relationship between high-skill returnees and innovation of Chinese publicly listed firms. To this aim, we construct a unique dataset of 2,499 firms over the period 2002–2016 by combining three different data sources (i.e. CNRDS, CSMAR, and LinkedIn). Our results show that different typologies of returnees (employees, technologists, and managers) with different experiences abroad (work versus study) may bring back different skills and impact differently on firm innovation.

Bilateral Economies of Scope in International Trade

Yao Amber Li, Sichuang Xu, Stephen R. Yeaple, Tengyu Zhao, Jan 15, 2025

This paper presents evidence that firms’ export and import decisions within the same foreign market are complementary, due to bilateral economies of scope that allow substantial cost savings when engaging in both activities. By quantifying these savings through a structural model, we show that bilateral economies of scope significantly enhance firms’ participation in international trade and amplify the effects of trade liberalization, offering new insights for policymakers and researchers.

Drive Down the Cost: Learning by Doing and Government Policies in the Global EV Battery Industry

Panle Jia Barwick, Hyuk-soo Kwon, Shanjun Li, Nahim Bin Zahur, Apr 16, 2025

Electric vehicle (EV) battery costs have fallen over 90% in the last decade. This study examines how learning-by-doing (LBD) drives this decline and interacts with government policies such as consumer EV subsidies and local content requirements. Leveraging rich data on EV models and battery suppliers from 13 countries with largest EV sales that account for 95% of global EV sales, we develop a structural model of the EV industry that incorporates consumer choices and pricing strategies by EV producers and battery suppliers....
