چکیده
Building upon Beaudry and Koop’s (1993) analysis, we consider a “current depth of the recession” (CDR) variable in modeling the time-series behavior of the postwar quarterly U.S. unemployment rate. The CDR approach is consistent with the state-dependent behavior in the unemployment rate documented in the business-cycle asymmetry literature. We show that while the CDR effect is significant in-sample, no statistically significant out-of-sample forecast improvement is obtained relative to the linear alternative. Augmenting an AR(2) model by inclusion of the CDR term, however, does not significantly worsen the out-of-sample forecast performance. Acknowledgment. We wish to thank an anonymous referee and Norm Swanson for helpful comments.

This paper investigates topologically semiconjugate dynamics as a macrorepresentation of microeconomic dynamics. The condition for its existence, its summarizing property, and its inferability property are discussed. As an example, we present a model of a temporary equilibrium price dynamic that has a topologically semiconjugate one-dimensional income dynamic, from which the nature of the origi...

This paper aims at testing and modeling business-cycle asymmetries within a structural time-series framework, allowing for smooth transition in the parameters characterizing the cyclical component, namely, the damping factor and the frequency. An LM test of linearity is derived, and illustrations are provided with reference to a set of quarterly U.S. industrial production series for two-digit m...

We investigate business cycle dynamics for 26 countries, estimating a set of nonlinear models for real GDP where appropriate. We find a great deal of heterogeneity in the dynamics of real output growth across countries. At the same time, a common feature is the asymmetric response of real GDP to shocks and the tendency for negative real GDP shocks to be less persistent than positive real GDP sh...
متن کاملThe Transient Dynamics of a Beam Mounted on Spring Supports and Equipped with the Nonlinear Energy Sink
The transient dynamics of a beam mounted on springer-damper support and equipped with a nonlinear energy sink (NES) is investigated under the effects of shock loads. The equations of motion are derived using the Hamilton’s principle leading to four hybrid ordinary and partial differential equations and descritized using the Galerkin method. An adaptive Newmark method is employed for accurate an...

There is now a great deal of empirical evidence that business cycle fluctuations contain asymmetries. I focus on a theoretical model intended to capture the nonlinear behavior of aggregate output following a large negative shock. Nonlinearity introduced by Bayesian updating and an information externality produces an economy in which the response to large negative shocks is an increase in future...

It is a common assertion that, in a world with perfect markets and rational expectations, endogenous cycles could only arise under very unrealistic assumptions. This paper offers a short discussion on this claim and a review of the relevant contributions to the literature on deterministic fluctuations in competitive models. It is argued that these types of fluctuations are more easily obtained ...
