This paper uses a new economic geography model to analyze tax competition b
etween two countries trying to attract internationally mobile capital. Each
government may levy a source tax on capital and a lump sum tax on fixed la
bor. If industry is concentrated in one of the countries, the analysis find
s that the host country will gain from setting its source tax on capital ab
ove that of the other country. In particular, the host may increase its wel
fare per capita by setting a positive source tax on capital and capture the
positive externality that arise in the agglomeration. If industry is not c
oncentrated, however, both countries will subsidize capital. (C) 2000 Elsev
