This paper proposes a simultaneous-equation approach to the estimation of the contribution of transport infrastructure accumulation to regional growth. We model explicitly the political-economy process driving infrastructure investments; in doing so, we eliminate a potential source of bias in production-function estimates and generate testable hypotheses on the forces that shape infrastructure policy. Our empirical findings on a panel of France's regions over 1985-92 suggest that electoral concerns and in°uence activities were, indeed, significant determinants of the cross-regional allocation of transportation infrastructure investments. By contrast, we find little evidence of concern for the maximization of economic returns to infrastructure spending, even after controlling for pork-barrel.
