This paper studies the pricing of money in an infinite-horizon economy with heterogeneous agents, incomplete financial markets and arbitrary borrowing restrictions. Purchases of the consumption good are subject to a cash-in-advance constraint. Under general conditions I show that the price of...

This paper analyzes the equilibrium dynamics of an endogenous growth model with physical and human capital in which leisure considerations have a direct effect on the utility function. Even in the absence of technological externalities our model may contain multiple balanced paths. These...

This paper studies the econometrics of computed dynamic models. Since these models generally lack a closed-form solution, economists approximate the policy functions of the agents in the model with numerical methods. But this implies that, instead of the exact likelihood function, the researcher...

In this paper we consider a sequential trading economy with incomplete financial markets and a finite number of infinitely lived agents. We propose a specification of agents' budget sets and show that such specification features several desirable properties. We then establish the existence of an...

This paper studies first–order differentiability properties of the value function in concave dynamic programs. Motivated by economic considerations, we dispense with commonly imposed interiority assumptions. We suppose that the correspondence of feasible choices varies with the vector of state...

This paper presents a recursive method for the computation of sequential competitive equilibria in dynamic models with heterogeneous agents and market frictions. This computational method builds on a convergent operator defined over an expanded set of state variables for which a Markovian...

In this paper we are concerned with the performance of stock option contracts in the provision of managerial incentives. In our simple framework, we restrict the space of contracts available to the principal to those conformed by a fixed payment and a call option on the firm’s stock. As...

This chapter is concerned with numerical simulation of dynamic economic models. We focus on some basic algorithms and study their accuracy and stability properties. This analysis is useful for an optimal implementation and testing of these procedures, as well as to evaluate their performance....
