Dans cet article, je mets en cause l'allégation de Duménil et Lévy selon laquelle 1'« approche classique » offrirait une alternative au cadre conceptuel d'Arrow-Debreu en théorie micro-économique. Plus spécifiquement, l'argumentation développée dans cet article est à l'effet que les...

We propose an endogenous growth model of a decentralized economy subject to environmental constraints. In a basic version, we consider an economy where final production requires some material input and where research activities allow simultaneously productive firms to reduce the dependency of...

This article proposes to insert a bank capital channel (BCC) in the theoretical framework proposed by Bernanke et al. (1999) (BGG), in order 1) to evaluate the mean features of the BCC and 2) to assess the benefits of a countercyclical prudential measure. In a costly state verification...

The paper introduces a two-factor model of the common leading and coincident economic indicators. Both factors are unobserved and each of them captures the dynamics of a corresponding group of the observed time series. The common leading factor is assumed to Granger-cause the common coincident...

Composite economic indicator is a very useful tool designed to trace and predict the business cycle conditions. In this paper we study possible extensions of this approach intended to cope with the potential data problems caused by various structural breaks affecting both level and volatility of...

The analysis and prediction of the short-run economic dynamics, or the evolution of the business cycle, often require a construction of the composite economic indicator (CEI). This indicator may be endowed with nonlinear dynamics to take care of the possible asymmetries between different phases...

In this paper, we consider a coincident economic indicator model with regime-switching dynamics and with the time series observed at different frequencies, for instance, at monthly and quarterly frequencies. Until now the only solution was to drop the lower frequency series and to estimate the...

One of the important tools of the business cycle research are the signal-extraction techniques (SETs). They allow to study both the stylized facts and the turning points of the business cycles. However, these are highly sensitive to the SETs. In this paper we try to see how some of the SETs...

Our paper presents a new rationale for innovation by incumbents. We show that the possibility to price-discriminate between consumers having different levels of wealth is a sufficient incentive for the industry leader to overcome the Arrow (1962) effect and keep investing in R&D, even in the...

This paper examines the dynamics of the skill supply and its incidence on economic growth in the presence of education policies. When there are indivisibilities in the financing of human capital, small differences in the initial distribution of skills may greatly affect the stationary...
