The paper analyzes two questions: (i) the effect of a monetary policy shock on the business cycle and (ii) the extent to which a shift in a monetary policy affects the dynamics of business cycle. Unlike previous literature, to answer these questions, we measure cycle movements by calculating an...

This paper examines a mechanism of liquidity-preference fluctuations caused by people's learning behavior. % about the frequency of a liquidity shock. When observing a financial shock, they rationally update their belief so that the subjective probability of encountering it again is higher,...

This paper analyzes a model of investment with fixed investment costs and capital market imperfections. In this model finance influences the level of capital firms hold, as well as the frequency at which they invest. In consequence investment reacts nonlinearly with respect to shocks to...

In this paper we investigate the relationship between stock market returns and economic activity by using signal decomposition techniques based on wavelet analysis. In particular, we apply the maximum overlap discrete wavelet transform (MODWT) to the DJIA stock price index and the industrial...

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 asks two questions. First, can we detect empirically whether the shocks recovered from the estimates of a structural VAR are fundamental? Second, can the problem of non-fundamentalness be solved by considering additional information? The answer to the firrst question is 'yes' and that...

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...
