We consider a pure exchange financial economy, where rational agents, possibly asymmetrically informed, forecast prices privately and, therefore, face "exogenous uncertainty", on the future state of nature, and "endogenous uncertainty" on future prices. At a sequential equilibrium, all agents...

In three related papers, we consider a pure exchange financial economy, where agents may observe private information signals, form private anticipations and face an "exogenous uncertainty", on the future state, and an "endogenous uncertainty", on the future prices. At a sequential equilibrium,...

We extend the Cornet-de Boisdeffre (2002-2009) asymmetric information finite dimensional model to a more general setting, where agents may forecast prices with some private uncertainty. This new model drops both Radner's (1972-1979) classical, but restrictive, assumptions of rational...

We consider a pure exchange financial economy, where agents, possibly asymetrically informed, face an "exogenous uncertainty", on the future state of nature, and an "endogenous uncertainty", on the future price in each random state. Namely, every agent forms private price anticipations on every...

L'objectif de ce papier est d'analyser les impacts du vieillissement de la population italienne sur le système économique et en particulier sur le système de retraite afin d'évaluer l'efficacité des réformes mises en place durant les années 90 (réforme Amato en 1992 et réforme Dini en...

Most European countries have recently introduced pension system reforms to face the financial problem related to population ageing. Italy is not an exception. The reforms introduced during the Nineties (Amato Reform in 1992 and Dini Reform in 1995), even if they will produce a strong reduction...

We consider an optimal growth model of an economy facing an exogenous pollution quota. In the absence of an international market of pollution permits, the economy has three instruments to reach sustainable growth: R&D to develop cleaner technologies, investment in new clean capital goods, and...

We study the impact of demographic change on economic short and long-term dynamics in an enlarged Lucas-Uzawa model with intratemporal altruism. Demographics are summarized by population growth rate and initial size. In contrast to the existing literature, the long-run level effects of...

This paper studies how credit rationing affects endogenous growth when capital and debt are related to the firm´s internal net worth, taken as collateral. The accumulation of firm´s net worth determines the growth rate of capital and the growth rate of the economy. The relation between growth...

In this paper, financial infrastructures increase the efficiency of the banking sector: they decrease the market power (due to horizontal differentiation) of the financial intermediaries, lower the cost of capital, increase the number of depositors and the amount of intermediated savings,...
