Size effect, neighbour effect and peripheral effect in cross-border tax games

This paper analyses a game theoretic model of tax competition in a system where tax authorities are revenue optimisers and countries are differentiated by size. The model accommodates more than two countries. In equilibrium, larger countries set higher tax rates non-cooperatively. By applying the Hotelling linear model, this paper gives examples where the size effect, neighbourhood effect, and peripheral effect coexist and push up the tax rate in equilibrium.
