Abstract: This paper studies the effects of congestion relief in a spatial general equilibrium model of Luxembourg and its cross-border commuting zone. Using traffic speed data, we apply a difference-in-differences design on Luxembourgs highways to measure congestion severity and identify choke points. We then simulate counterfactual scenarios where highway speeds are set to free-flow levels and track the resulting changes in output, welfare, and fiscal revenues. Economic output rises in Luxembourg City and Esch, while other cities lose production but gain in resident welfare. For residents of Luxembourg City, we estimate a short-run welfare loss of €1,140 per person per year, which becomes a welfare gain of €3,490 in the long run after population reallocation. When accounting for migration from the outside economy, the welfare effect in Luxembourg City turns negative at €8,110 per person per year. The elimination of congestion induces a fiscal gain of €2.50 billion per year in the short run, €1.18 billion in the long run, and €7.04 billion when accounting for migration inflows.
