Asset Pricing with Dynamically Inconsistent Agents

Khapko, Mariana - 2016

This paper develops a framework to study general equilibrium implications for an economy in which agents are allowed to have dynamically inconsistent time and risk preferences. This framework accommodates, but is not limited to, the following settings: (1) non-exponential discounting; (2)...

A New Theory of Information Acquisition and Recovery : Intrinsic Geometry Approach with Asset Pricing Applications

Leung, Raymond C. W. - 2018

We introduce a novel geometry-based method of modelling information that encompasses entropy-based approaches. A key contribution is that we explicitly construct the optimal path to acquire information. The economic driver of this geometry-based framework is knowledge state dependent marginal...

Arbitrage Pricing under Uncertainty

Rocciolo, Francesco - 2021

This paper studies the implications of arbitrage in a large asset market under conditions of (Knightian) uncertainty.First, I adapt the notion of arbitrage to a market in which the assets' returns are affected by uncertainty across probability distributions. The setting delivers the analog of...

Ambiguous Information, Portfolio Inertia, and Excess Volatility

Illeditsch, Philipp K. - 2011

I study the effects of risk and ambiguity (Knightian uncertainty) on optimal portfolios and equilibrium asset prices when investors receive information that is difficult to link to fundamentals. I show that the desire of investors to hedge ambiguity leads to portfolio inertia and excess...

An Empirical Evaluation of the Black-Litterman Approach to Portfolio Choice

Gofman, Michael - 2012

We evaluate the Black-Litterman equilibrium model approach to portfolio choice. We quantify the improvement in portfolio performance of a privately informed investor who learns from market prices over an equally informed, but dogmatic investor who only uses private information. We extend the...

Shadow Probability Theory for Asset Pricing under Ambiguity

Izhakian, Yehuda (Yud) - 2011

Assuming that probabilities (capacities) of events are random, this paper introduces a novel model of decision making under ambiguity, called Shadow probability theory, a generalization of the Choquet expected utility. In this model, probabilities of observable events in a subordinated...

Consumption-Based Asset Pricing with Herd Behavior

Curatola, Giuliano - 2012

This paper analyzes the link between herd behavior and asset prices in a multi-good pure-exchange economy where investors' preferences evolve over time in response to the consumption decisions of other investors. More precisely, the rule of updating preferences incorporates a bandwagon effect,...

Stock-Market Prices with Forgetful Investors

Nocetti, Diego - 2009

This note investigates the impact of investors' memory limitations on stock-market prices. I consider a simple asset-pricing model in which investors allocate limited cognitive resources to retrieve information from memory and to learn about the data generating process of multiple assets. I show...

Retail Investor Recognition and the Cross Section of Stock Returns

Chang, Eric C. - 2013

We test and offer support to Merton's (1987) theory that difference in a stock's investor recognition affects its cost of capital. In the U.S. market, using the breadth of ownership among retail investors as a proxy for investor recognition, we show that a long-short portfolio based on the...
