The Economic History Review, Volume 79, Issue 3, Page 1235-1264, August 2026.Abstract We develop new datasets of monthly grain prices in 14 urban markets and of the storage and marketing of grain by 5 rural estates located in western Germany between the late seventeenth century and c. 1860. We explore whether observed patterns of monthly prices, sales, and storage of grain are consistent with the rational competitive storage ...

Trade Liberalization and Labor Market Monopsony Power: Evidence From China
Review of International Economics, Volume 34, Issue 3, Page 632-657, August 2026.ABSTRACT We study the effect of trade liberalization on firms' monopsony power in the labor market. We estimate firm‐specific markdowns from production data in the manufacturing industry and document the trends in China between 1998 and 2007. Taking China's entry to the WTO as a policy shock, we use a difference‐in‐differences (DiD) approach combined ...
