Marcet and Marimon (1994, revised 1998) developed a recursive saddle point method which can be used to solve dynamic contracting problems that include participation, enforcement and incentive constraints. Their method uses a recursive multiplier to capture implicit prior promises to the agent(s)...

In this paper we examine the effect of collateral constraints and margin requirements on the prices of long-lived assets. We consider a Lucas-style infinite-horizon exchange economy with heterogenous agents and collateral constraints. In our calibrated economy collateral constraints lead to a...

In this paper we examine the volatility of asset returns in a canonical stochastic overlapping generations economy with sequentially complete markets. We show that movements in the in- tergenerational wealth distribution strongly affect asset prices since older generations have a lower...

In this paper we examine the competitive equilibria of a dynamic stochastic economy with complete markets. We show that the completeness of the market requires both the set of asset payoffs and collateral levels to be sufficiently rich, so as to allow to decentralize the equilibrium allocations...

In this paper we examine the effect of collateral requirements on the prices of long- lived assets. We consider a Lucas-style infinite-horizon exchange economy with heteroge- nous agents and collateral constraints. There are two trees in the economy which can be used as collateral for short-term...

In this paper we develop a Negishi approach to characterize recursive equilibria in stochastic models with overlapping generations. When competitive equilibria are Pareto-optimal, using Negishi-weights as a co-state variable has three major computational advantages over the standard approach of...

The analysis will be carried out in a relatively simple set-up, where the various effects of social security, on the prices of long-lived assets and the stock of capital, and hence on output, wages and risky rates of returns, can be clearly identified.

In this paper we show that competitive equilibrium prices and margin requirements naturally lead to too much leverage relative to the constrained optimum. We describe two mechanisms through which equilibrium forces lead agents to borrow too much and to hold too little collateral. To illustrate...
