We study a dynamic and in nite{dimensional model with Knightian uncertainty modeled by incomplete multiple prior preferences. In in- terior e cient allocations, agents share a common risk{adjusted prior and use the same subjective interest rate. Interior e cient alloca- tions and equilibria...

We study a dynamic and infinite–dimensional model with incomplete multiple prior preferences. In interior efficient allocations, agents share a common risk–adjusted prior and subjective interest rate. Interior efficient allocations and equilibria coincide with those of economies with...

This paper constructs a closed set Y in Rl such that for all y in the boundary of Y, Clarke's normal cone to Y at y is equal to Rl+. If Y is the production set of a firm, then the marginal cost pricing rule imposes no restriction. The existence of Y is shown to be equivalent to the existence of...

While the empirical evidence tends to support some predictions of the life-cycle theory, a number of puzzles remain: an ageing-consumption, an ageing-saving, a saving-capitalisation and a saving-longevity puzzles have been put forward in the literature. This paper analyses the links between...

This paper analyses the impact of welfare systems and longevity on savings. It develops a life-cycle model embodying social transfers (health care and pension expenditures) and changes in longevity to determine the level of household savings. We simulated an aggregate saving equation and derived...

This paper examines the channels through which ageing will shape the main economic factors that in turn affect potential growth; identifies current policy settings that may in fact amplify the adverse impact of demographic trends; and sets out policy reforms that will work to temper the effects...

If the allocations of a differential information economy are defined as incentive compatible state-contingent lotteries over consumption goods, competitive equilibrium allocations exist and belong to the (ex ante incentive) core. Furthermore, any competitive equilibrium allocation can be viewed...

In this paper we propose a generalization of the comonotonicity notion by introducing and exploring the concept of conditional comonotonicity. We characterize this notion and we show on examples that conditional comonotonicity is the natural extension of the concept of comonotonicity to dynamic...

To assess how financial markets and commodities are inter-related, this paper introduces a ‘volatility surprise’ component into the asymmetric DCC with one exogenous variable (ADCCX) framework. We develop an econometric model in which returns and volatility allow to influence pairs of...
