The recent period has highlighted a well-known phenomenon, namely the existence of a positive bias in experts’ anticipations. Literature on this subject underlines optimism in the financial analyst community. In this work, our significant contributions are twofold: we provide explanatory bias...

In this article, we extend Brouwer's fixed point theorem – which states that every continuous mapping f :B→B (a closed ball of Rn ) must have a fixed point – by allowing discontinuities of f, and we apply this extension to equilibrium theory in Economics.

Under a comonotonicity assumption between aggregate dividends and the market portfolio, the CCAPM formula becomes more tractable and more easily testable. In this paper, we provide theoretical justifications for such an assumption.

Unilateral climate policy, such as carbon pricing, represents an additional cost to the economy, especially to energy-intensive industrial sectors, as well as those exposed to international competition. A border carbon adjustment (BCA) is often presented as an attractive policy option for...

Social planners in most western countries will be facing two long-lasting challenges in the next years: energy transition and fiscal consolidation. One problem is that governments might consider that implementing an energy transition could get i n the way of achieving a fiscal consolidation. If...

The demographic structure of a country influences economic activity. The "second dividend" modifies growth. Accordingly, in general equilibrium, the second dividend and the demographic structure are interrelated. This paper aims at assessing empirically the "second dividend" in a dynamic,...

A rising share of renewables in the energy mix push es up the average price of energy - and so does a carbon tax. However the former bolsters the accumulation of capital whereas the latter, if fully recycled, does not. Thus, in general equilibrium, the effects on growth and intertemporal welfare...

In this paper we prove the existence of general equilibrium with transaction costs generalizing Hahn's (Review of Economic Studies, 1973, 40, 449-461) model by introducing producers and nonconvexities (in particular we allow for increasing returns in transaction sets). We also recover any...

The end of the Multifiber Agreement in January 2005 had a negative impact on the Tunisian apparel industry, but the effects were weaker than expected. Using a dynamic general equilibrium model, the article provides a prospective assessment of the impact on Tunisia of the phase out of the MFA and...
