We consider a semi endogenous R&D growth model with international trade, firm heterogeneity, and local knowledge spillover in a closed economy and international knowledge spillover in a symmetric two country economy. We show that by opening trade R&D difficulty (the number of varieties produced)...

We model international tax competition allowing for agglomeration forces and heterogeneous firms. This provides a new perspective since a tax schedules have different effects on the international relocation decision of small and large firms (large firms are endogenously more sensitive to tax...

Heterogeneity in firm productivity affects the location patterns of firm and agglomeration. Here we provide an economic geography model, involving forward and backward linkages driven by the migration of a footloose entrepreneur (capital owner) with different productivity. As a result we find a...

We propose a general model of monopolistic competition and derive a complete characterization of the market equilibrium using the concept of Relative Love for Variety. When the RLV increases with individual consumption, the market generates pro-competitive effects. When it decreases, the market...

This paper studies anti-agglomeration subsidies in a core-periphery setting when firms are heterogeneous in labour productivity, focusing on the effects of relocation subsidy on firm location in various tax-financing schemes (local versus global). We discuss how subsidy can enhance welfare in...
