Agglomeration Externalities in Ecuador. Do Urbanisation and Tertiarisation Matter?

Congestion Tolling with Agglomeration Externalities*

Consider an urban economy with two types of externalities, negative traffic congestion externalities and positive agglomeration externalities deriving from non-market interaction. Suppose that urban travel can be tolled, that non-market interaction cannot be subsidized, and that non-market interaction is stimulated by a reduction in travel costs. Then the optimal toll is below the congestion ex...

Knowledge Externalities , Agglomeration Economies , and Employment Growth in Dutch Cities

This paper extends the work of Glaeser et al. (1992) by looking at effects of agglomeration economies on employment growth in Dutch city-industries and in very small (postal) zip code-industries in the Dutch province of South-Holland. At both levels of geographic detail, findings are broadly consistent with results from the earlier study in that employment growth is enhanced by industrial diver...

A Dynamic Firm Location Choice Model with Agglomeration Externalities

This paper outlines a dynamic model of firm location choice, in an environment which includes both agglomeration effects and stochastic productivity shocks. The model follows closely the methods of Hopenhayn (1992) and his treatment of firm level entry and exit decisions. However, this model adds the complexity of a second location, as well as the existence of spillover effects, or agglomeratio...
