Public infrastructure provision in the presence of terms‐of‐trade effects and tax competition

Abstract

AbstractThis paper analyses and compares the performance of resource taxes and capital taxes in financing public goods while considering the positive effects of public expenditure on firm productivity. It is motivated by Franks et al. (2017), who argue that the advantage of the resource tax consists in its potential to reap foreign resource rents. I employ an analytical general equilibrium framework of identical resource‐poor countries, where local firms use internationally mobile capital and a net imported resource in production as well as local public infrastructure. The latter is financed solely by either taxing the input of the resource or capital. The choice of the policy instrument is exogenous to policy makers and symmetric across countries. I find that expenditure on infrastructure renders the impact of fiscal policy on the terms of trade ambiguous under resource taxation and negative under capital taxation. Moreover, public expenditure weakens the outflow of factors moderating the deficit of public spending caused by tax competition. This holds for both policy scenarios. Considering both effects simultaneously, resource taxation cannot generally be identified as the policy to provide higher provision or efficiency. A numerical exercise shows cases for higher provision of either policy.
