Fiscal Policy and External Adjustment: New Evidence

Relatively little empirical evidence exists about countries’ external adjustment to changes in fiscal policy and, in particular, to changes in taxes. This paper addresses this question by measuring the effects of tax and government spending shocks on the current account and the real exchange rate in a sample of four industrialized countries. Our analysis is based on a structural vector autoregression in which the interaction of fiscal variables and macroeconomic aggregates is left unrestricted. Identification is instead achieved by exploiting the heteroscedasticity of the structural disturbances. Three main findings emerge: (i) the data provide little support for the twin-deficit hypothesis, (ii) the estimated effects of unexpected tax cuts are generally inconsistent with the predictions of standard economic models, except for the US, and (iii) the puzzling real depreciation triggered by an expansionary public spending shock is substantially larger in magnitude than predicted by traditional identification approaches.Government spending, current account, exchange rate, taxes, structural vector auto-regression, twin deficits

Measuring the Effects of Fiscal Policy

Measuring the effects of discretionary fiscal policy is both difficult and controversial, as some explicit or implicit identifying assumptions need to be made to isolate exogenous and unanticipated changes in taxes and government spending. Studies based on structural vector autoregressions typically achieve identification by restricting the contemporaneous interaction of fiscal and non-fiscal variables in a rather arbitrary way. In this paper, we relax those restrictions and identify fiscal policy shocks by exploiting the conditional heteroscedasticity of the structural disturbances. We use this methodology to evaluate the macroeconomic effects of fiscal policy shocks in the U.S. before and after 1979. Our results show substantive differences in the economy’s response to government spending and tax shocks across the two periods. Importantly, we find that increases in public spending are, in general, more effective than tax cuts in stimulating economic activity. A key contribution of this study is to provide a formal test of the identifying restrictions commonly used in the literature.Fiscal policy, Government spending, Taxes, Primary deficit, Structural vector auto-regression, Identification

External and Budget Deficits in Developing Countries

This paper documents and explains the positive comovement between external and budget deficits for several developing countries. First, the covariance estimated from post-1960 time-series data is numerically positive for each of the 24 countries and statistically significant for almost all cases. This is consistent with previous findings obtained from panel regressions. Second, the empirical covariance is close to that predicted from a tractable small open economy, overlapping generation model with heterogeneous goods. Also, the predicted covariance is induced by shocks which are closely related to internal conditions such as domestic resources and fiscal policies, and to a much lesser extent to external conditions such as the world interest rate, real exchange rate, and terms of trade. This structural analysis explaining the joint behavior of external and budget deficits sharply contrasts with earlier reduced-form studies characterizing the individual behavior of either the external deficit or budget deficit

Abstract Measuring the effects of discretionary fiscal policy is both difficult and controversial, as some explicit or implicit identifying assumptions need to be made to isolate exogenous and unanticipated changes in taxes and government spending. Studies based on structural vector autoregressions typically achieve identification by restricting the contemporaneous interaction of fiscal and non-fiscal variables in a rather arbitrary way. In this paper, we relax those restrictions and identify fiscal policy shocks by exploiting the conditional heteroscedasticity of the structural disturbances. We use this methodology to evaluate the macroeconomic effects of fiscal policy shocks in the U.S. before and after 1979. Our results show substantive differences in the economy's response to government spending and tax shocks across the two periods. Importantly, we find that increases in public spending are, in general, more effective than tax cuts in stimulating economic activity.
