We obtain an exact necessary and sufficient condition for the existence and uniqueness of equilibrium asset prices in infinite horizon, discrete-time, arbitrage free environments. Through several applications we show how the condition sharpens and improves on previous results. We connect the condition, and hence the problem of existence and uniqueness of asset prices, with the recent literature on stochastic discount factor decompositions. Finally, we discuss computation of the test value… Expand

Existence and uniqueness of equilibrium in Lucas’ asset pricing model when utility is unbounded
This note presents a proof of the existence of a unique equilibrium in a Lucas (Econometrica 46(6):1429–1445, 1978) economy when the utility function displays constant relative risk aversion, and theExpand
Solving Asset Pricing Models When the Price-Dividend Function is Analytic
TLDR
A new method is presented for solving asset pricing models, which yields an analytic price-dividend function of one state variable, which lets us assess the accuracy of any numerical solution procedure used in the asset pricing literature. Expand
Rational asset pricing bubbles
This paper provides a fairly systematic study of general economic conditions under which rational asset pricing bubbles may arise in an intertemporal competitive equilibrium framework. Our mainExpand
Higher-Order Effects in Asset-Pricing Models with Long-Run Risks
This paper analyzes both the existence of solutions to long-run risk asset pricing models as well as the practicality of approximating these solutions by the Campbell-Shiller log-linearization. WeExpand
THE ROLE OF CONDITIONING INFORMATION IN DEDUCING TESTABLE RESTRICTIONS IMPLIED BY DYNAMIC ASSET PRICING MODELS1
The purpose of this paper is to investigate testable implications of equilibrium asset pricing models. The authors derive a general representation for asset prices that displays the role ofExpand
Quantitative Asset Pricing Implications of Endogenous Solvency Constraints
We study the asset pricing implications of an economy where solvency constraints are determined to efficiently deter agents from defaulting. We present a simple example for which efficientExpand

Quadrature-Based Methods for Obtaining Approximate Solutions to Nonlinear Asset Pricing Models
This paper develops a discrete state space solution method for a class of nonlinear rational expectations models. The method works by using numerical quadrature rules to approximate the integralExpand
Arbitrage and equilibrium in economies with infinitely many commodities
Abstract An ‘arbitrage opportunity’ for a class of agents is a commodity bundle that will increase the utility of any of the agents and that has non-positive price. The non-existence of ‘arbitrageExpand
Using Asset Prices to Measure the Persistence of the Marginal Utility of Wealth
We derive a lower bound for the volatility of the permanent component of investors' marginal utility of wealth or, more generally, asset pricing kernels. The bound is based on return properties ofExpand
