Hodrick-Prescott (HP) Filter of (most often, seasonally adjusted) quaterly series is analysed. Some of the criticism to the filter are adressed. It is seen that, while filtering strongly affects autocorrelations, it has little effect on crosscorrelations. It is argued that the criticism that HP...

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...

It is well known from time series analysis that shocks to aggregate output have very persistent effects. This paper argues that the relation between the expected growth rate of a firm and its size\ provides a microfoundation for such aggregate persistence. The empirical evidence indicates that...

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 aim of this paper is to reveal empirically two kinds of mechanismis which operate on inventories: one is demand related and the other is supply related.

Many quantitative studies have shown a stylised fact that fluctuations in business fixed investment dominate the business cycle pattern. The dynamics of the investment process have historically been seen as important elements of capital formation and economic progress. Why is it then that...

On presente dans cet article un cadre general -celui de la "concurrence monopolistique cournotienne" - permettant de mettre en valeur la maniere dont la concurrence sur le marche des biens peut, en presence de rendements croissants et d'une variabilite des facteurs de marge, etre a l'origine de...

We adress the issue of optimal growth when standard-of-living aspirations are transmitted from one generation to the next. We derive the condition for the optimal solution to be stable in the saddle-point sense and show that this optimal solution may display damped oscillations even when the...

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...
