We are interested in general equilibrium incomplete markets, where the number of consumers is N, the number of goods is L, and the dimension of the space of admissible trades is K (the case of complete markets being then K=(L−1)). We prove that, if N≥K, any non-vanishing analytic function...

This paper examines qualitative properties of efficient insurance contracts in the presence of background risk. In order to get results for all strictly risk-averse expected utility maximizers, the concept of “stochastic increasingness” is used. Different assumptions on the stochastic...

In this paper, we prove an existence theorem for approximated equilibria in a class of discontinuous economies. The existence result is a direct consequence of a discontinuous extension of Brouwer’s fixed point Theorem (1912), and is a refinement of several classical results in the standard...

This paper addresses partly an open question raised in the Handbook of Mathematical Economics about the orientability of the pseudo-equilibrium manifold in the basic two-period General Equilibrium with Incomplete Markets (GEI) model. For a broad class of explicit asset structures, it is proved...

We develop a nonlinear dynamic general equilibrium model with a banking sector and use it to study the macroeconomic impact of introducing a minimum liquidity standard for banks on top of existing capital adequacy requirements. The model generates a distribution of bank sizes arising from...

We study the effects of job-security provisions through the lens of a search-matching model with risk-neutral employers, risk-averse workers and incomplete asset markets. This setting limits the ability of agents to reallocate payments over time, and thereby to undo any mandatory transfer...

Pension systems often entail some compulsory saving over which individuals have some degree of choice in terms of the pension plan in which to invest. Our contribution analyses whether the choice between alternative plans is affected by the presence of liquidity constraints during working life....

We build a general equilibrium model where agents are subject to endogenous trading constraints, making the access to financial trade dependent on prices and consumption decisions. Besides, our framework is compatible with the existence of endogenous financial segmentation and credit markets'...

We study the tax systems that arise in a once-and-for-all majority voting equilibrium embedded within a macroeconomic model of inequality. We find that majority voting delivers (i) a small set of outcomes, (ii) zero labor income taxation, and (iii) nearly zero transfers. We find that majority...

We study the dual formulation of the utility maximization problem in incomplete markets when the utility function is finitely valued on the whole real line. We extend the existing results in this literature in two directions. First, we allow for nonsmooth utility functions, so as to include the...
