This paper formulates a model of retirement behavior based on the solution to a stochastic dynamic programming problem. The workers objective is to maximize expected discounted utility over his remaining lifetime. At each time period the worker chooses how much to consume and whether to work...

In this paper, we provide an overview of an emerging class of "monotone map methods" in analyzing distorted equilibrium in dynamic economies. In particular, we focus on proving the existence and characterization of competitive equilibrium in nonoptimal versions of the optimal growth models. We...

This paper provides a new characterization result for path independent choice functions (PICF) on finite domains and uses that characterization as the basis of an algorithm for the construction of all PICFs on a finite set of alternatives, V, designed by an a priori given set I of initial...

This paper uses lattice programming methods along with the extension of Tarski's fixed point theorem due to Veinott (1992) and Zhou (1994) to establish sufficient conditions for existence of sequential symmetric Markov equilibrium in a large class of dynamic games. Our method is constructive and...

In an economy with a continuum of individuals, each individual has a stochastic, continuously evolving endowment process. Individuals are risk averse and would therefore like to insure their endowment processes. It is feasible to obtain insurance by pooling endowments across individuals because...

This paper analyzes an infinite horizon model where a seller, who owns an indivisible unit of a good for sale, has incomplete information about the state of the world that determines not only the demand she faces but also her own valuation for the good. Over time, she randomly meets potential...

We show that monotone methods, especially, those based on lattice theory and lattice programming can produce results, e.g., on the monotonicity of the optimal programs, as well as on the existence of fixed points, consistent with the current macroeconomics literature, in the absence of...

Willig (1976) argues that the change in consumer's surplus is often a good approximation to the willingness to pay for a price change: if the income elasticity of demand is small, or the price change is small, then the percentage error from using consumer's surplus is small. If the price of a...
