This paper investigates the effects of introducing imperfect competition in an international business cycle model. We provide some international evidence on markups and analyze the implicactions of increasing returns to scale and monopolistic competition for the effects and the international...

Multi-countru models have not been very successful in replicating features of the international transmission of business cycles. Standard models predict cross-country correlations of output and consumption which are respectively too low and loo high. In this paper, we built a multi-country model...

This paper studies relationships between the determinacy of a stationary equilibrium in the perfect foresight dynamics, and its local stability in dynamics arising from econometric learning procedures. There is no clear links in linear scalar economies where agents forecast only one perods...

Spectral analysis at frequencies other than zero plays an increasingly important role in econometrics. A number of alternative automated data-driven procedures for nonparametric spectral density estimation have been suggested in the literature, but little is known about their finite-sample...

More than thirty years ago Milton Friedman proposed a 'plucking' model of business fluctuations in which output cannot exceed a ceiling level, but will, from time to time, be plucked downward by recession. The model implied that business fluctuations are asymmetric, that recessions have only a...

We explore the business-cycle implications of agency problems between firms and financiers. We show how these problems create liquidity shortages that can lead to corporate bankruptcy, and may generate aggregate, endogenous cycles in an economy that otherwise would have had a unique, stationary...

The liquidity effect, defined as a decrease in nominal interest rates in response to a monetary expansion, is a major stylized fact of the business cycle. This paper seeks to understand under what conditions such an effect can be explained in a general equilibrium model with sticky prices and...

Structural models are apowerful tool for business cycle and monetary analysis because they are invariant to either policy changes or external stocks. In this paper, we derive a sidrauski-type model in which both the demand and supply side are structural in the sense that the behavorial equations...

Markov switching models with time-varying means, variances and mixing weights are applied to characterize business cycle variation in the probability distribution and higher order moments of stock returns.
