The dynamic effects of tax policies in a small open economy

Abstract

We develop an intertemporal optimizing model of a small open economy with both durable and nondurable consumption to address the implications of alternative tax policies. An increase in lump sum taxes reduces the steady state level of consumption and improves the stock of foreign bonds. Consistent with empirical evidence, durable consumption exhibits initial excess volatility. Though an increase in the tax on durables increases the demand for nondurables and improves the bond holdings in the steady state, an increase in the tax on nondurables has insignificant effects on the stock of foreign bonds and the consumption of durables. Using quarterly data from the UK and estimating generalized impulse response functions we find empirical support. We also calibrate the welfare implications of different tax policies.
