This survey reviews models of self-reinforcing mechanisms that cause poverty to persist.
Some of them examine market failure in environments where the neoclassical assumptions …

The economics literature is replete with examples of monotone comparative statics; that is,
scenarios where optimal decisions or equilibria in a parameterized collection of models vary …

The literature on supermodular optimization and games is surveyed from the perspective of
potential users in economics. This methodology provides a new approach for comparative …

This paper studies the interaction between a single long-lived principal and a series of short-
lived agents in the presence of both moral hazard and adverse selection. We assume that …

Groundwater management with stochastic surface flows and artificial recharge is
considered. Theoretical analysis characterizes the decision rules and establishes conditions …

A rigorous and example-driven introduction to topics in economic dynamics, with an
emphasis on mathematical and computational techniques for modeling dynamic systems …

This paper examines existence, continuity, and characterization of optimal paths under
“recursive” preferences. Current utility is a fixed (aggregator) function of current consumption …

We examine the labor market effects of incomplete information about the workers' own job‐
finding process. Search outcomes convey valuable information, and learning from search …

This paper develops several comparative dynamics results for Ramsey-type
multidimensional dynamic optimization problems in economics. We provide sufficient …

Using lattice programming and order theoretic fixpoint theory, we develop a new class of
monotone iterative methods that provide a qualitative theory of Markovian equilibrium …
