This paper examines the incentives of regions to levy source-based cap
ital taxes, when the tax revenue is not needed to finance the regional
public sector. It is assumed that capital is completely mobile among
regions, but that labour is completely immobile. Since each region can
produce the same two tradable goods, using the same technology, then
differences in tax rates on capital will lead to some specialization.
If residents of one region own more of the nation's capital (per perso
n), then these tax differences may be an equilibrium phenomenon. Regio
ns with below-average capital endowment per person will levy capital t
axes to lower the cost of the capital they import, even though these t
axes lead to capital flight, and specialization in the labour-intensiv
e good.
