What Accounts for the Changes in U.S. Fiscal Policy Transmission?

Using vector autoregressions on U.S. time series for 1957–79 and 1983–2004, we find government spending shocks to have stronger effects on output, consumption, and wages in the earlier period. We try to account for this observation within a DSGE model featuring price rigidities and limited asset market participation. Specifically, we estimate the structural parameters of the model for both periods by matching impulse responses. Model‐based counterfactual experiments suggest that most of the changes in fiscal policy transmission are accounted for by increased asset market participation and the more active monetary policy of the Volcker–Greenspan period.     

Fiscal Adjustment and Inflation Targeting in Less Developed Countries

Inflation targeting may not be viable in less developed countries (LDCs) where policymakers rely too heavily on cuts in infrastructure investment to balance the budget. Using a mix of analytical and numerical methods, we demonstrate that the equilibrium ceases to be saddle point stable under active policy when infrastructure cuts account for 30–70% of fiscal adjustment and the return on infrastructure exceeds a comparatively low threshold value. The result is robust to the form of the Taylor rule, the degree of real wage flexibility, the initial level of debt, the choice of a balanced‐budget or debt‐targeting rule, and the q‐elasticity of private investment spending.     

Propagation Mechanisms for Government Spending Shocks: A Bayesian Comparison

The inability of a simple real business cycle model to predict a rise in consumption in response to increased government expenditures, observed in many empirical studies, has stimulated the development of alternative theories of government spending shocks. Using the Bayesian approach, we evaluate the quantitative performance of five extant models, and find that neither of the considered transmission mechanisms for government spending helps improve the fit of the baseline model. Moreover, we find that consumption decreases in all estimated models in response to a rise in government spending.
