The paper studies the impact of a switch from free to charged highway provision on firm numbers and private sector employment in a cross-section of Portuguese municipalities. It exploits the fact that highway tolls in Portugal were unexpectedly raised in reaction to the financial crisis to establish causality. Results from a difference-in-differences analysis indicate a significantly negative effect of highway tolls on number of firms and employment in treated municipalities vis-à-vis the control group. We also find negative effects of tolls in municipalities not directly traversed by the treated highways, with larger firms and manufacturing firms being most strongly affected.
