Sources of Entropy in Representative Agent Models
Backus, David K. - 2011
preferences, habits, and jumps. The metrics describe the pricing kernel's dispersion (the entropy of the title) and dynamics (time … dependence, a measure of how entropy varies over different time horizons). We show how each model generates entropy and time … approximations -- clarifies the mechanisms underlying these models. It also reveals, in some cases, tension between entropy, which …

Investor Information, Long-Run Risk, and the Term Structure of Equity
Croce, Mariano (Max) Massimiliano - 2012
We study the role of information in asset pricing models with long-run cash flow risk. When investors can distinguish short- from long-run consumption risks (full information), the model generates a sizable equity risk premium only if the equity term structure slopes up, contrary to the data. In...

Asset Return Dynamics Under Bad Environment Good Environment Fundamentals
Bekaert, Geert - 2010
We introduce a "bad environment-good environment" technology for consumption growth in a consumption- based asset pricing model. Using the preference structure from Campbell and Cochrane (1999), the model generates realistic time-varying volatility, skewness and kurtosis in fundamentals while...

The Long-Run Risks Model and Aggregate Asset Prices : An Empirical Assessment
Beeler, Jason; Campbell, John Y. - 2021
The long-run risks model of asset prices explains stock price variation as a response to persistent fluctuations in the mean and volatility of aggregate consumption growth, by a representative agent with a high elasticity of intertemporal substitution. This paper documents several empirical...

A Revealed Preference Analysis of Asset Pricing Under Recursive Utility
Epstein, Larry G. - 2006
This paper considers a representative agent model of asset prices based on a recursive utility specification. A constant elasticity of intertemporal substitution is assumed but the risk-preference component of utility is restricted only by qualitative, nonparametric regularity conditions. The...

The Pricing of Event Risks with Parameter Uncertainty
Froot, Kenneth - 2010
Financial instruments whose payoffs are linked to exogenous events, such as the occurrence of a natural catastrophe or an unusual weather pattern depend crucially on actuarial models for determining event (e.g., default) probabilities. In many instances, investors appear to receive premiums far...

Optimal Beliefs, Asset Prices, and the Preference for Skewed Returns
Brunnermeier, Markus K. - 2007
Human beings want to believe that good outcomes in the future are more likely, but also want to make good decisions that increase average outcomes in the future. We consider a general equilibrium model with complete markets and show that when investors hold beliefs that optimally balance these...

The Leverage Effect Puzzle : Disentangling Sources of Bias at High Frequency
Ait-Sahalia, Yacine - 2011
The leverage effect refers to the generally negative correlation between an asset return and its changes of volatility. A natural estimate consists in using the empirical correlation between the daily returns and the changes of daily volatility estimated from high-frequency data. The puzzle lies...

Margin-Based Asset Pricing and Deviations from the Law of One Price
Garleanu, Nicolae - 2011
In a model with heterogeneous-risk-aversion agents facing margin constraints, we show how securities' required returns are characterized both by their betas and their margin requirements. Negative shocks to fundamentals make margin constraints bind, lowering risk-free rates and raising Sharpe...

International Consumption Risk is Shared after All : an Asset Return View
Lewis, Karen K. - 2012
International consumption risk sharing studies have largely ignored their models' counterfactual implications for asset returns although these returns incorporate direct market measures of risk. In this paper, we modify a canonical risk-sharing model to generate more plausible asset return...
