A panel session was organised at the 5th "Dijon" Post-Keynesian Conference (Roskilde University - 13th-14th May 2011) in order to confront three recent interpretations of Keynes's principle of effective demand: that of Hartwig (2007), Hayes (2007) and Allain (2009). Allain's comments on Hartwig...

The double dividend literature studies the simultaneous pursuit of two objectives - improving the quality of the environment through the introduction or enhancement of an environmental tax (first dividend) and increased social welfare by reducing distortions induced by the whole the tax system...

Short-term increasing returns to production factors are usually found in empirical studies. We argue they can be due to omitted variables, particularly the intensity of factor utilisation. Thanks to original French firm-level data (1992-2008), we show how increasing returns to scale disappear...

Most of the theoretical and empirical studies on the Home Market Effect (HME) assume the existence of an \outside good" that absorbs all trade imbalances and equalizes wages. We study the consequences on the HME of removing this assumption. The HME is attenuated and, more interestingly, it...

This paper provides a new framework for monetary macro-policy, where the Central Bank potentially intervenes both on short-term and long-term loans markets, and can do this alternatively by manipulating interest rates or money supply. Following Bonnisseau and Orntangar (2010) and Giraud and...

L'étude de la relation paysage - marché n'est pas aisée car elle met en perspective deux réalités difficiles à appréhender : le marché et le paysage. L'introduction du présent ouvrage a exposé une revue des approches et des définitions du paysage. Pour ce chapitre la définition...

We consider an empirical model of worldwide airline alliances that we apply to a large set of companies for the period 1995-2000. Using observations at the network level, we estimate a cost, capacity, and demand system that accounts for cross-price elasticities. Our contribution consists in...

In two recent contributions, Herbert Gintis introduces agent-based imitation models built upon evolutionary bargaining games where agents use private prices as strategies. He reports surprising convergence results for simulations performed in exchange economies where goods are strict complement....

This paper presents a theoretical model of remanufacturing where a duopoly of original manufacturers produces a component of a final good. The specific component that needs to be replaced during the lifetime of the final good creates a secondary market where independent remanufacturers enter the...

The current transformation of capitalism is characterised by a full-fledged comeback and proliferation of forms of rent parallel to a complete change in the relationship between wages, rent and profit. To demonstrate our hypothesis, this article is divided in two sections: in the first section...
