This paper investigates how exposure to a mentally disordered peer influences middle school students' social preferences after the 2008 Sichuan earthquake. Leveraging random classroom assignments, height-based seating, and lab-in-the-field experiments, the study finds that having a disabled peer significantly increases altruism, primarily driven by empathy among students with shared trauma. These results underscore the role of peer effects in fostering social cohesion and prosocial behaviors, highlighting a self-recovery mechanism that may mitigate secondary trauma and enhance welfare.

Despite emerging academic interest in place-based policies, their impact on long-term structural transformation remains under-investigated, especially in developing countries. This study explores the combined effects of infrastructure development (highway, industrial park, and school establishments) in transforming agrarian communities in the Philippines using 40 years of family dynasty data, combined with satellite imagery and public administrative data. The results suggest that infrastructure development has led to long-lasting structural transformations by increasing the probability of employment in modern sectors and facilitating human capital investments. Both the demand and supply sides of labor are key to self-sustaining modernization through place-based policies.

This study employs unique data from Indonesia to investigate whether and how digitalization of micro, small, and medium-sized enterprises (MSMEs) helped them weather the adverse shocks from the pandemic and resulting lockdowns. The main empirical result is that, in the pandemic’s early phases, digitalized MSMEs disproportionately encountered negative effects on their business outcomes. The seemingly harmful elements of digitalization disappeared during later stages. The findings provide critical implications for industrial and competition policies related to MSMEs during the COVID-19 recovery process.

This paper explores the role of market mechanisms and price adjustments in structural transformation and economic development, focusing on the Green Revolution. Using theoretical insights on equilibrium market prices, we employ shift-share (Bartik) instrumental variables to address endogeneity in relative prices. Empirical results show that while the Green Revolution enhanced agricultural productivity, lowered crop prices, and shifted labor to non-agriculture, market imperfections and price distortions exacerbated misallocation—measured by the Price-Based Misallocation (PBM) index—diminishing its overall benefits. Realizing the Green Revolution’s full potential requires well-functioning market mechanisms, highlighting the need for institutional reforms and targeted policies to correct inefficiencies and optimize agricultural innovation gains.
