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....

Pension reforms are on the political agenda of many countries. Such reforms imply an increasing responsibility on individuals’ side in building an efficient portfolio for retirement. In this paper we provide a model describing workers’ choices on the allocation of retirement savings in...

In OLG framework, it is generally admitted that PAYG pension system generates a lower capital accumulation, a higher level of interest rate but is more inequality reducing. By taking into account different assets returns and unequal access to them, we find that the PAYG pension system generates...

We study continuous-time optimal consumption and investment with Epstein-Zin recursive preferences in incomplete markets. We develop a novel approach that rigorously constructs the solution of the associated Hamilton-Jacobi-Bellman equation by a fixed point argument and makes it possible to...

We develop a method that allows one to compute incomplete-market equilibria routinely forMarkovian equilibria (when they exist). The main difficulty to be overcome arises from the setof state variables. There are, of course, exogenous state variables driving the economy but, in anincomplete...

We study consumption-portfolio and asset pricing frameworks with recursive preferences and unspanned risk. We show that in both cases, portfolio choice and asset pricing, the value function of the investor/representative agent can be characterized by a specific semilinear partial differential...

This paper studies the welfare properties of competitive equilibria in an economy with incomplete markets subject to idiosyncratic and aggregate shocks. We focus on the role of securitization, whereby borrowers can reduce idiosyncratic asset risk, which enables increased leverage and investment....

We propose an extension of the incomplete markets general equilibrium model with production to situations in which firms default. In the model, firms are assumed to be owned by a single individual whose roles as entrepreneur and consumer are anonymous. Assets are exogenously collateralised and...
