No. 1
Harris Dellas and George Tavlas revisit the historic postwar dollar shortage debate between Charles Kindleberger and Milton Friedman, a central controversy in international monetary history. The analysis contrasts Kindleberger’s structural argument for persistent dollar demand with Friedman’s market-based skepticism, framing the dispute within broader debates over exchange rate regimes and policy intervention. For a scholar whose doctoral research examined French postwar exchange controls and oil import quotas, this piece directly engages with the intellectual foundations of dollar shortage theories that underpinned European reconstruction policies.

The geography of opportunity after the Civil War: Black and white Americans’ intra- and intergenerational mobility into property ownership
This study, appearing in Explorations in Economic History, uses historical microdata to trace intra- and intergenerational property ownership mobility for Black and white Americans after the Civil War. The paper quantifies how institutional and geographic factors shaped divergent wealth trajectories in the post-emancipation period, providing a rigorous quantitative benchmark for one of the most consequential episodes in American economic history. For a scholar of economic history who has studied postwar European reconstruction, this analysis offers a comparative framework for understanding how policy and institutions affect long-run economic opportunity.

Trade Sophistication and Economic Development Stages in the Context of Global Digitalization
This study analyzes the relationship between trade sophistication and economic development across 119 countries from 2003 to 2024, finding that GDP per capita has a positive but diminishing effect on export and import sophistication. Digitalization emerges as the dominant driver of trade sophistication in high-income countries, while GDP remains the primary factor for low-income economies. For a professional with experience in applied economics and policy evaluation at the EIB, these findings offer evidence on how industrial structure and digital transformation interact at different development stages, informing investment and policy decisions.

Cashless tax systems: voluntary vs. mandated digital payments in Eswatini
Using administrative tax data from Eswatini’s 2021 zero-cash-handling mandate, this paper employs staggered and treatment-intensity difference-in-differences designs to analyze the impact of digital tax payments on compliance. Voluntary adoption reduced late payments by 19–20 percentage points and increased payment accuracy, while the mandate raised average tax paid by 17% but reduced accuracy for companies. For a policy evaluator experienced in institutional finance and investment analysis, this study provides rigorous causal evidence on how taxpayer heterogeneity and enforcement design affect compliance outcomes in digital tax systems.
