This paper is about involuntary unemployment in general equilibrium models with imperfect competition. It surveys papers written after the seminal work of d'Aspremont, Dos Santos Ferreira and Gérard-Varet (1984). This unemployment is called involuntary because it exists at any wage. It results...

This paper examines underemployment fluctuations in an OG model with cournotian competition on the market for a good. In the case of constant returns, it demonstrates the existence conditions of a stable two-period cycle (in prices and employment amounts) in the backward perfect foresight...

...We rely on Matsuyama (1996, 1999) to study the effects on growth and welfareof non distortive tax/subsidy policies. In particular, we are interested ininvestigating the stabilising/destabilising effects of policies aimed at eliminatingeconomic fluctuations. The focus on stabilisation...

We examine the OLG model of Reichlin (1986). By using the Helleman's method (1980), we show that the difference equation of the model can be locally studied from the Feigenbaum equation. We can then explain the existence of endogenous fluctuations acording to the productivity level and the...

Non-formal education programmes are active in a number of developing countries. These programmes offer vulnerable students an opportunity to pursue their education although they were excluded for various reasons from the formal education systems. This paper examines the impact of two programmes...

The renormalization procedure facilitates the detection of periodic and chaotic patterns of many two-dimensional systems of nonlinear equations. We first give a comprehensive presentation of this procedure. We then generalize it to make it more applicable to economic frameworks. Copyright...
