Many OECD countries are aiming to reform their tertiary education (TE) systems. This work explores the determinants of the investment in TE, with a focus on institutional setting of TE systems and private incentives to undertake years of schooling beyond upper-secondary degree level. For this...

This paper reconsiders the theory of existence of efficient allocations and equilibria when consumption sets are unbounded below under the assumption that agents have incomplete preferences. Our model is motivated by an example in the theory of assets with short-selling where there is risk and...

We propose a simple equilibrium model, where the physical and the derivative markets of the commodity interact. There are three types of agents: industrial pro- cessors, inventory holders and speculators. Only the two first of them operate in the physical market. All of them, however, may...

The theory of existence of equilibrium with short-selling is reconsidered under risk and ambiguity modelled by risk averse variational preferences. No-arbitrage conditions are given in terms of risk adjusted priors. A sufficient condition for existence of efficient allocations is the overlapping...

We address the problem of a social planner who, as in Weitzman (2001), gathers data on discount rates and wants to infer the socially efficient consumption discount rate. We propose an equilibrium approach and we analyse the expression and the properties of the resulting equilibrium discount...

The theory of existence of equilibrium with short-selling is reconsidered under risk and ambiguity modelled by risk averse variational preferences. A sufficient condition for existence of efficient allocations is that the relative interiors of the risk adjusted sets of expectations overlap. This...

In this paper, we show that behavioral features can be obtained at a group level when the individuals of the group are heterogeneous enough. More precisely, starting from a standard model of Pareto optimal allocations, with expected utility maximizers and exponential dis- counting, but allowing...

We discuss the relevance of the volatility as a risk measure. By considering recent studies on tick by tick data and specific features of derivatives, we introduce alternative measures to take into account the time and volume effects, or the distributional asymmetry.

The investigations reported in this article examined some of the individual and situational determinants of the level of cognitive product differentiation in consumer products judgements, Subjects consisted of four large samples of male and female consumers in two large metropolitan areas in the...

In this note, we consider an economy with heterogeneous agents, differing by their time preference rate and by their beliefs. We show that at the Pareto optimum, the representative agent exhibits interesting behavioral properties. More precisely, starting from a standard model with expected...
