My research lies at the intersection of industrial organization, international trade, and macroeconomics. I study how firm-level behavior and market power shape welfare and aggregate outcomes.

Market Power and Firm-Level Welfare Incidence
Which firms account for the welfare cost of market power? This paper develops a firm-level welfare-incidence measure for markup dispersion. The measure maps firm markups, size, sectoral demand curvature, and benchmark markups into the change in aggregate welfare generated by reducing an individual firm’s markup gap. I implement the framework using Belgian firm-level accounting data from 1980 to 2024.

Aggregating Markups in Production Networks
How should firm-level markups be aggregated when production takes place through input–output networks? We derive an aggregate markup consistent with household incidence and show how cost-based exposure weights trace distortions through the production network. We bring the framework to near-universe Belgian firm-to-firm data.
Working paper
Market Power and Firm-Level Welfare Impact in Production Networks
Which firms matter most for the welfare cost of market power in a production network? We map firm-level markups and firm-to-firm linkages into aggregate welfare losses and firm-level welfare effects, then implement the framework using Belgian administrative transaction data.

Technological Knowledge Intensity and Intergenerational Mobility across U.S. Regions
This paper studies the regional relationship between technological knowledge intensity and intergenerational upward mobility in the United States. Combining mobility measures from the Opportunity Atlas with U.S. patent records, I document that regions with greater patent-based knowledge intensity exhibit higher upward mobility.

Equal Static Gains, Unequal Growth: Trade and the Allocation of R&D
Can trade reforms that deliver the same current real-income gain have opposite effects on long-run growth? This paper studies firms’ R&D choices when sectors compete for a fixed national supply of research labor. It derives an equal-static-gain growth frontier and quantifies the mechanism in a multi-country, multi-sector model with input–output linkages.

When Comparison Makes Markets Tip
Policies that make platforms easier to compare are expected to lower prices. This paper shows that, in two-sided markets, greater comparability can also strengthen participation feedback and destabilize coexistence. It distinguishes comparison policies from interventions that weaken network feedback, such as interoperability and multi-homing support.

Are We More Accurate? Revisiting the European Commission’s Macroeconomic Forecasts
This paper reassesses the accuracy of the European Commission’s macroeconomic forecasts and studies how forecast performance has evolved over time.
