We estimate the effect of interstate highways on the level and composition of trade for us cities. Highways within cities have a large effect on the weight of city exports with an elasticity of approximately 0.5. We find little effect of highways on the total value of exports. Consistent with...

The aim of this paper is to qualify the claim that regulating a competitive transport sector is always detrimental to consumers. We show indeed that, although transport deregulation is beneficial to consumers as long as the location of economic activity is fixed, this is no longer true when, in...

We estimate the effects of major roads and public transit on the growth of major cities in the US between 1980 and 2000. We find that a 10% increase in a city’s stock of roads causes about a 2% increase in its population and employment and a small decrease in its share of poor households over...

This paper estimates the effect of access to transportation networks on regional economic outcomes in China over a twenty-period of rapid income growth. It addresses the problem of the endogenous placement of networks by exploiting the fact that these networks tend to connect historical cities....

The direct impact of local public goods on welfare is relatively easy to measure from land rents. However, the indirect effects on home and job location, on land use, and on agglomeration benefits are hard to pin down. We develop a spatial general equilibrium model for the valuation of these...

This Paper develops an argument explaining why retail prices may rise in response to the deregulation of opening hours. We make this point in a model of imperfect duopolistic competition. In a deregulated market retailers view the choice of opening hours as a means to increase the degree of...

We investigate the causal effect of market structure on market performance in the consumer electronics. We combine data from Austria's largest online site for price comparisons with retail data on wholesale prices provided by a major hardware producer for consumer electronics. We observe input...

This Paper investigates how the formation of larger buyers affects a supplier's profits and, by doing so, his incentives to undertake non-contractible activities. We first identify two channels of buyer power, which allows larger buyers to obtain discounts. We subsequently examine the effects of...

This Paper analyses the impact of retail mergers on product variety. We show that a merging firm may want to enhance its buyer power vis a vis suppliers by delisting products and committing to a ‘single-sourcing’ purchasing strategy. Anticipating this, suppliers will strategically choose to...

We develop a model of competition between retailer chains with a structural estimation of the demand and supply in the supermarket industry in France. In the model, supermarkets compete in price and brand offer over all food products to attract consumers, in particular through the share of...
