Sustained endogenous growth is known to be impossible in OLG one-sector models without non-convexities and externalities, unless income is redistributed to the young generation. No redistribution proper is however necessary, as shown in two simple examples, if positive profits accruing to young...

We study employment dynamics using an OLG model with unemployment benefits and universal old-age survival pensions, both financed by taxing employed workers. The novelty is that we explicitly introduce workers' social norms that shape both the individual participation decision of workers and...

We approach business cycles on the basis of extrinsic uncertainty, related to static indeterminacy of free entry oligopolistic equilibria. Firms, producing under increasing returns to scale, compete in prices in contestable markets. The number of active firms varies across sectoral equilibria,...

The Paper approaches business cycles in terms of extrinsic uncertainty related, not to dynamic indeterminacy of intertemporal equilibria (in the neighborhood of an attractor) or to multiplicity of steady states (in non-linear models), but to static indeterminacy of free entry oligopolistic...

<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...
