In this paper, we extend the partial equilibrium urban model of DeSalvo (1985) to include mode choice. DeSalvo demonstrated that the urban model of Muth (1969) was robust to the extension to leisure choice. We show that the model is robust to mode choice as well. In addition, we derive the...

The standard approach to estimating the economic impact of a port overestimates the port's direct impacts on exports and imports. The overestimates result because all export and import activity in the impact area is assumed to fall to zero in the absence of the port. We argue that this...

Some urban policies are designed to reduce auto and increase transit usage. Evidence is mixed because most empirical research uses ad hoc specifications. We estimate empirical models of the interaction between urban form and transit demand drawn from urban economic theory. Population density has...
