This paper provides some further tests for the proposition that a larger public sector leads to smaller output volatility. Both Gali and Fatas & Mihov have provided some evidence which appears to support this proposition. Their evidence is, however, based on a relatively small sample of...

This paper examines the impact of macroeconomic policy shocks in a Real- Business-Cycle Model with money. In addition to technology shocks, I include government consumption, government investment, tax rate and monetary policy as sources of random disturbances. Money is introduced in a...

In this paper we reconcile two opposing views about the elasticity of intertemporal substitution in consumption (EIS). Empirical studies using aggregate consumption data typically find that the EIS is close to zero (Hall, 1988). Calibrated models designed to match growth and fluctuations facts...

We estimate output growth rate spectra for 58 countries. The spectra exhibit diverse shapes. To study the sources of this diversity, we estimate the short-run, business cycle, and long-run frequency components of the sampled series. For most OECD countries the bulk of the spectral mass is in the...

This paper studies the co-movements of unemployment and labor productivity growth for the U.S. economy. Measures of co-movements in the frequency domain indicate that co-movements between variables differ strongly according to the frequency. First, long-term and business cycle co-movements are...

This paper investigates the asymmetric effects of monetary shocks when the=20 impact of monetary policy on real activity works through state-dependent=20 variables. We use a nonlinear model, the multiple regime smooth transition=20 autoregressive model, that allows the effects of shocks to vary...

Standard stochastic growth models provide theoretical restrictions on output decomposition which can be used to investigate whether productivity shocks played a major role in observed business cycles. Applying these restrictions to US data leads to the following findings: i) Business cycles...

A controversial result of some current research on the real business cycles is the claim that a common stochastic trend(the cumulative effect of permanent shocks to productivity)underlies the bulk of economic fluctuations. If confirmed, this will imply that many other forces have been relatively...

Constructing a general equilibrium model which compactly incorporates the markets for outputs, labor, money, and equities, we examine equilibrium unemployment. While a mechanism of an efficiency wage brings about nominal wage rigidity, unemployment occurring in our model definitely has Keynesian...
