In Keynes’ beauty contest, agents have to choose actions in accordance with an expected fundamental value and with the conventional value expected to be set by the market. In doing so, agents respond to a fundamental and to a coordination motive respectively, the prevalence of either motive...

Since the seminal work of Becker, the dynamics of endogenous fertility has been based on the trade-off faced by parents between the quantity and the quality of their children. However, in developing countries, when child labor is an indispensable source of household income, parents actually...

The paper proposes a model of household behavior with both private and public consumption where the spouses independently maximize their utilities, but taking into account, together with their own individual budget constraints, the collective household budget constraint with public goods...

A comprehensive model of economic household decision is presented which incorporates both fully cooperative and fully non-cooperative variants, parameterized by the income distribution, as well as a semi-cooperative variant, parameterized in addition by a vector B, representing the degrees of...

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...

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 paper suggests a <italic>new Keynesian</italic> model of the <italic>General Theory</italic>. A reduced form entails a diagram with three curves relating employment and the real wage, which represent the two fundamental classical postulates and the principle of effective demand. This diagram illustrates better than <italic>IS-LM</italic> the...

Free entry equilibria are usually characterized by the zero profit condition. We plead instead for a strict application of theNash equilibriumconcept to a symmetric simultaneous game played by actual and potential entrants, producing under decreasing average cost. Equilibrium is then typically...

The paper aims to make a claim for a retrospective approach to history of economic analysis. While not denying that a contextualised methodology might be useful, or maybe even imperative in some cases, the history of economic analysis we favour should consist in the inquiry of ‘historic’...
