La correcta medida del riesgo tiene una importancia fundamental en la valoración de activos. Sin embargo, una de las medidas más frecuentemente utilizadas, la varianza, ha recibido críticas debido a que establece una respuesta simétrica para movimientos positivos y negativos en las...

We develop a conditional capital asset pricing model in continuous-time that allows for stochastic beta exposure. When beta co-moves with market variance and the stochastic discount factor (SDF), beta risk is priced, and the expected return on a stock deviates from the security market line. The...

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...

We revisit the specification of GARCH processes with Johnson Su innovations examined in Choi and Nam [2008. Journal of Empirical Finance 15, 41–63]. This model, allowing for skewed and leptokurtic innovations, has many advantages over well known alternatives. We examine a simpler version of...

We study returns on over-the-counter stocks and find that these returns are extremely negative on average. The distribution of OTC stock returns is highly positively skewed: while many of the stocks in our sample become worthless, a few do extremely well. We investigate whether this negative...
