Although transport costs are a key-ingredient of New Economic Geography, the transport sector is usually abstracted away from the analysis. Put differently, freight rates are taken as parametric and are not set by the market. This paper studies the relationships between transport costs, industry...

We analyze the equilibrium and the optimal resource allocations in a monocentric city under monopolistic competition. Unlike the constant elasticity of substitution (CES) case, where the equilibrium markups are independent of city size, we present a variable elasticity of substitution (VES) case...

We compare the impact of falling transport costs, borne by firms, and decreasing tariffs, borne by either firms or consumers, on the regional distribution of economic activities. Our main result shows that tariffs and tranport costs play symmetric roles in that a decrease in either of them...

We develop a spatial general equilibrium model in which the absence of trade is an endogenous outcome and we show that trade is not a necessary condition for agglomeration to arise. More precisely, extending the model developed by Ottaviano et al. [13], we show that equilibria without trade...

We extend the quadratic utility approach by Ottaviano et al. [19] and by Behrens [1] to the range of intermediate values of transport costs in or- der to investigate how asymmetric trade affects the regional distribution of economic activities. Asymmetry in trade is an endogenous result of price...

We propose a quantity-based 'dual' version of the gravity equation that yields an estimating equation with both cross-sectional interdependence and spatially lagged error terms. Such an equation can be concisely estimated using spatial econometric techniques. We illustrate this methodology by...
