Key findings
Economics · International Economics
No. 1
This paper investigates how the concentration of trade across sectors shapes the distribution of income, distinguishing groups that benefit from globalization from those that lose. It provides empirical evidence that sectoral trade concentration amplifies income inequality, with implications for trade and industrial policy design. For a scholar whose work spans exchange controls and industrial planning, this study offers a modern framework for evaluating how trade structure affects distributional outcomes and the design of compensatory mechanisms.

The geography of opportunity after the Civil War: Black and white Americans’ intra- and intergenerational mobility into property ownership
This study examines patterns of intra- and intergenerational property ownership mobility for Black and white Americans in the decades following the Civil War. Using historical census and property records, the authors document how geographic factors—such as location-specific economic conditions and institutional legacies—shaped divergent mobility trajectories. For an economic historian who studied the role of state intervention in industrial planning, this work provides a compelling parallel showing how policy and geography interacted to determine economic opportunity and asset accumulation.

Technical Change Through Global Value Chains: Evidence From Firms Worldwide
Using firm-level data covering 144 countries from 2006 to 2025, this study provides causal evidence that global value chain participation drives innovation and productivity, with gains stemming primarily from importing rather than exporting activities. Product innovation responds more strongly than process innovation, and the nature of innovation differs by development level: lower-income countries benefit from technology access, while advanced economies engage in more R&D-intensive innovation. For an economist with experience at the European Investment Fund and Bank, this paper offers direct empirical support for policies that facilitate integration into global supply chains as a channel for technical upgrading and structural transformation.

Property tax incidence and housing market in Taiwan
This study integrates three competing views of property tax incidence into a DSGE model and applies it to Taiwan’s housing tax reform. It finds that a hoarding tax on investment housing fails to lower investment property prices when residential and investment housing are complements, and instead pushes the tax burden onto residential housing; in contrast, a direct tax on residential housing effectively moderates prices and consumption. For a policy professional who has evaluated institutional finance and fiscal instruments, this analysis underscores how the elasticity of substitution between housing types critically determines tax incidence and the effectiveness of real estate taxation.

Climate change and migration
This research documents that extreme temperatures in El Salvador destroy farm jobs and push workers abroad, linking climate shocks directly to migration flows. The evidence highlights how environmental stress disrupts agricultural labor markets and drives migration through existing migrant networks. For an applied economist who has evaluated investment and policy interventions, this study provides a framework for understanding climate-related labor displacement and the potential role of adaptation investments in resilient sectors.
