Modeling a micro-structure of agglomeration economies, this article derives a second-best benefit evaluation formula for urban transportation improvements. Without explicitly modeling the sources of agglomeration economies, Venables (JTEP 2007) investigated the same problem. This article...

This paper is motivated by the fact that, contrary to its importance in practice, the role of land for production has received no attention in the new trade theory and the new economic geography. We set up a simple monopolistic competition model and we show that, due to the factor proportions...

Many sources of urban agglomeration involve departures from the first-best world. By modeling the microstructure of agglomeration economies, we derive second-best benefit evaluation formulae for urban transportation improvements. Previous work has investigated the same problem, but without...
