This paper is concerned with testing the time series implications of the capital asset pricing model (CAPM) due to Sharpe (1964) and Lintner (1965), when the number of securities, N, is large relative to the time dimension, T, of the return series. Two new tests of CAPM are proposed that exploit...

This paper generalizes the standard mean–variance paradigm to a mean–variance–ambiguity paradigm by relaxing the assumption that probabilities are known and instead assuming that probabilities are themselves random. It extends the CAPM from risk to uncertainty by incorporating ambiguity....

There exist many anomalous relationships between firm characteristics and average asset returns which are inconsistent with the predictions of the Capital Asset Pricing Model (CAPM). The size and value effects are two such well known empirical anomalies (see Fama and French, 1992, 1993). The...

We extend the Consumption-based CAPM (C-CAPM) model to representative agents with different risk attitudes. We first use the concept of expectation dependence and show that for a risk averse representative agent, it is the first-degree expectation dependence (FED) rather than the covariance that...

Convertible arbitrageurs combine long positions in convertibles with short positions in the underlying stock. We exploit worldwide differences in short-sale constraints to examine whether convertible arbitrage short selling creates downward pressure on convertible issuers' stock prices. Using a...

The phrase 'equity premium puzzle' refers to the apparent inability of the standard asset-pricing paradigm to explain the average size of the equity premium in US data. In order to describe this failure it is useful to outline the essential features of the basic intertemporal equilibrium model...

In this paper, we develop lower bounds on the variance of the permanent component and the transitory component, and on the variance of the ratio of the permanent to the transitory components of SDFs. Exactly solved eigenfunction problems are then used to study the empirical attributes of asset...

We study risk-return relationship in twenty Frontier country stock markets by setting up an international version of the intertemporal capital asset pricing model (International ICAPM). The systematic risk in this model comes from covariance of Frontier market stock index returns with world...

This is the first paper to test the asset pricing implication of leverage in a laboratory. We show that as theory predicts, leverage increases asset prices: When an asset can be used as collateral (that is, when the asset can be bought on margin), its price goes up. This increase is significant,...
