The paper studies the impact of a switch from free to charged highway provision on firm numbers and private sector employment in a panel of Portuguese municipalities covering the period 2007–2013. It exploits the fact that tolls on certain highways in Portugal were unexpectedly introduced in reaction to the sovereign debt 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 comparison 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.
