For an industry producing a composite commodity, we propose a comprehensive concept of oligopolistic equilibrium, allowing for a parameterized continuum of regimes varying in competitive toughness. Each firm sets simultaneously its price and its quantity under two constraints, relative to its...

The cyclical behavior of wages and prices was a central topic in trade cycle analysis on the eve of the Second World War. Keynes and Harrod independently referred in the same year to the supposed countercyclicality of real wages, a feature that was contested soon after, on empirical grounds, by...

A simple general equilibrium model of imperfect competition is introduced with special attention given to the labour market. An extended Cournot equilibrium is defined for any money wage taken as given by the producers. Under some assumptions involuntary unemployment may arise, that is...

<title>Abstract</title> On the basis of the 19th century mathematical economics literature initiated by Cournot, the paper shows the coexistence of two contrasting views of competition, which may be associated, as already suggested by Edgeworth, with the two themes of peace and war. According to the first view...

<title>Abstract</title> Cournot's <italic>Recherches</italic> contains a sketch of the general equilibrium research programme, as well as the model of an exchange economy as a system verifying Walras' law. General equilibrium analysis had nonetheless to wait for Walras to occupy the centre of theoretical economics, since it...

[eng] The question of the wages-employment relationship stemmed from the statistical invalidation by Dunlop and Tarshis, immediately after the publication of the General Theory, of a conjecture formulated by Keynes on the alleged negative correlation between real and money wages. All three...
