The purpose of this paper is to demonstrate that inherited human capital is a powerful vector of inequality formation and persistence, irrespective of its links with financial wealth endowment. This paper argues that the agents who inherit a low level of human capital bear a greater utility cost...

Keynes' principle of effective demand constitutes a pillar for Post Keynesians theories. But Keynes' presentation remains difficult to interpret, mainly because the aggregate demand function is based on entrepreneurs' expectations. The problem is then to demonstrate how these entrepreneurs...

This paper develops and analyses a dynamic model, which combines both the adoption and the industry evolution theories. We model the decision of adoption, learning entry and exit of firms. These decisions depend on the interaction of technology characteristics (effectiveness, machinery and...

Technical determinism is often presented as a shortcoming of the old neoclassical approach of which the "new theories" are supposed to be ridded. This paper shows that technical determinism is nevertheless still present.

In this paper, we study a version of the static Jain-Mirman (2002) model in which competition in the real sector is introduced. In this paper, we add competition in the stock sector to the Jain-Mirman (2002) paper. We show that the linear equilibrium structure is affected by this competition in...

The paper extends the Drèze's Criterion [Investment under private ownership : optimality, equilibrium and stability, in «Allocation under Uncertainty ; Equilibrium and Optimality», Wiley, New York, 1974, p.129] for firms to non-smooth and non-convex technologies and to non-ordered preferences...

The note explores a vertical differentiation model with continuous non-uniform consumers' distribution. First some results concerning the finiteness property obtained with uniform consumers' distribution are generalized. Second we prove an existence result of price equilibrium when the...

This paper analyses empirically the role of financial market imperfections in the way countries' exports react to a currency depreciation. Using quarterly data for 27 developed and developing countries over the period 1990-2005, we find that the impact of a depreciation on exports will be less...

This paper studies how market-specific entry sunk costs (regulation costs) affect the Home Market Effect (HME) with firm heterogeneity in marginal costs. our model is based on the Dixit-Stiglitz monopolistic competition model with firm heterogeneity plus regulation costs difference. We find that...

In this paper, we build a renewed labour supply model in order to explain why the RMI recipients don't «fall in poverty traps» but on the contrary accept to work even for low wages. The standard consumption-leisure trade-off is extended : we consider that one needs a minimum consumption level...
