Does idiosyncratic risk matter: another look
We show that the equal-weighted average stock volatility analyzed by Goyal and Santa-Clara (GS, 2003) forecasts stock returns because of its co-movements with stock market volatility. Moreover, contrary to the positive relation hypothesized by GS and many others, we find that the value-weighted average stock volatility is negatively related to future stock returns when combined with stock market volatility. This puzzling result reflects the fact that the alue-weighted average stock volatility is negatively correlated with the consumption-wealth ratio, and its predictive power vanishes if we ...

Is value premium a proxy for time-varying investment opportunities: some time series evidence
We uncover a positive, empirical risk-return tradeoff in the stock market after controlling for the covariance of stock market returns with the value premium. The underlying premise is that, as conjectured by Fama and French (1996), the value premium is a proxy for time-varying investment opportunities. By ignoring the value premium, early specifications suffer from an omitted variable problem that leads to a downward bias in the estimate of the risk-return tradeoff. The paper also documents a new finding on a significantly positive relation between the value premium and its conditional ...

Limited stock market participation and asset prices in a dynamic economy
We present a consumption-based model that explains the equity premium puzzle through two channels. First, because of borrowing constraints, the shareholder cannot completely diversify his income risk and requires a sizable risk premium on stocks. Second, because of limited stock market participation, the precautionary saving demand lowers the risk-free rate but not stock return and generates a substantial liquidity premium. Our model also replicates many other salient features of the data, including the first two moments of the risk-free rate, excess stock volatility, stock return ...

Foreign exchange volatility is priced in equities
This paper finds that standard asset pricing models fail to explain the significantly positive delta hedging errors from writing options on foreign exchange futures. Foreign exchange volatility does influence stock returns, however. The volatility of the JPY/USD exchange rate predicts the time series of stock returns and is priced in the cross-section of stock returns. Foreign exchange volatility risk might be priced because of its relation to foreign exchange level risk. ; Earlier title: Is foreign exchange delta hedging risk priced?

Uncovering the risk-return relation in the stock market
There is an ongoing debate about the apparent weak or negative relation between risk (conditional variance) and expected returns in the aggregate stock market. We develop and estimate an empirical model based on the ICAPM that separately identifies the two components of expected returns?the risk component and the component due to the desire to hedge changes in investment opportunities. The estimated coefficient of relative risk aversion is positive, statistically significant, and reasonable in magnitude. However, expected returns are driven primarily by the hedge component. The omission of ...

Idiosyncratic volatility, economic fundamentals, and foreign exchange rates
This paper shows that a relatively high level of average U.S. industry- or firm-level idiosyncratic stock volatility is usually associated with a future appreciation in the U.S. dollar. For most foreign currencies, the relation is statistically significant in both in sample and out-of-sample tests, even after we use a bootstrap procedure to explicitly account for data mining. We also document a positive and significant relation between a country?s idiosyncratic volatility and the future U.S. dollar price of its currency?in France, Germany, and Japan. Moreover, among a number of commonly used ...
