Using a semi-supervised topic model on 7,000,000 New York Times articles spanning 160 years, we test whether topics of media discourse predict future stock and bond market returns to test rational and behavioral hypotheses about market valuation of disaster risk. Focusing on media discourse...

Empirical evidences regarding the association of idiosyncratic volatility and stock returns are inconsistent with the Capital Asset Pricing Model (CAPM), which implies that idiosyncratic risk should not be priced because it would be fully eliminated through diversification. Using Exponential...

To attenuate an inherent errors-in-variables bias, portfolios are widely employed for risk premium estimation; but portfolios might diversify away and thus mask relevant risk- or return-related features of individual assets. We propose a resolution that allows the use of individual assets while...

We decompose the non-diversifiable market risk into continuous and discontinuous components and jump systematic risks into positive vs. negative and small vs. large components. We examine their association with equity risk premia across major equity markets. We show that developed markets jumps...

To attenuate an inherent errors-in-variables bias, portfolios are widely employed to test asset pricing models; but portfolios might mask relevant risk- or return-related features of individual assets. We propose an instrumental variables approach that allows the use of individual stocks as test...

The Fama-Macbeth (1973) rolling-beta method is widely used for estimating risk premiums, but its inherent errors-in-variables bias remains an unresolved problem, particularly when using individual assets or macroeconomic factors. We propose a solution with a particular instrumental variable,...
