Bansal and Yaron (2004) demonstrate, by calibration, that the Consumption-Based Capital Asset Pricing Model (CCAPM) can be rescued by assuming that consumption growth rate follows a stochastic volatility model. They show that the conditional equity premium is a linear function of conditional...

This paper assesses the quantitative impact of ambiguity on the historically observed financial asset returns and prices. The single agent, in a dynamic exchange economy, treats the conditional uncertainty about the consumption and dividends next period as ambiguous. We calibrate the agent's...

This paper introduces state dependent utility into the standard Mehra and Prescott (1985) economy by allowing the representative agent's coefficient of relative risk aversion to vary with the underlying economy's growth rate. Existence of equilibrium is proved and its asymptotic properties...

In this paper, we match both the first and the second moments of the equity premium and the risk-free rate by endowing the agents in the economy with disappointment aversion preferences and by making the joint process of consumption and dividends follow a Hamilton's (1989) Markov switching...

Probably not. First, allowing the probabilities of the states of the economy to differ from their sample frequencies, the Consumption-CAPM is still rejected in both U.S. and international data. Second, the recorded world disasters are too small to rationalize the puzzle unless one assumes that...

The representative agent model (RA) has dominated macroeconomics for the last thirty years. This model does a reasonably good job of explaining the co-movements of consumption, investment, GDP and employment during normal times. But it cannot easily explain movements in asset prices. Two facts...

This paper is concerned with empirical and theoretical basis of the Efficient Market Hypothesis (EMH). The paper begins with an overview of the statistical properties of asset returns at different frequencies (daily, weekly and monthly), and considers the evidence on return predictability, risk...

We develop a simple overlapping generations model in which the young have a choice in investing in equities and index-linked bonds. Projections of share price uncertainty over a 30-year period show that the risk associated with such a long-term investment predicts an equity premium that matches...

We propose a consumption-based capital asset pricing model in which the representative agent's preferences display state-dependent risk aversion. Since a common factor - the state of the world - influences both stock prices and preferences, we obtain a valuation equation in which the vector of...
