Reindustrialization meets rural reality: The limits of foreign direct investment‐led development
Contemporary Economic Policy, EarlyView.Abstract As industrial policy drives new waves of foreign direct investment (FDI) into the U.S., rural areas are becoming key destinations. Using synthetic control, difference‐in‐differences, and propensity score matching, I examine whether rural FDI translates job growth into higher incomes.

The role of structural transformation in regional convergence in Japan: 1874–2008
The Economic History Review, EarlyView.Abstract Japan's regional convergence of productivity levels throughout the twentieth century can be best described as a cumulative process of ‘catching up, forging ahead, and falling behind’. Using a novel dataset spanning 135 years (1874–2008), this study finds support for a crucial role played by structural transformation in convergence. The pace of
