Expected returns vary when investors face time-varying investment opportunities. Longrun risk models (Bansal and Yaron 2004) and no-arbitrage affine models (Duffie, Pan, and Singleton 2000) emphasize sources of risk that are not observable to the econometrician.

Recent research has identified several industry-related patterns that standard asset pricing models cannot explain effectively. This paper investigates whether industry commodity dependence affects the cross section of stock returns, using the case of oil industry. The results show that in the...

We provide a better understanding of the causal structure in a multivariate time series by introducing a novel statistical procedure for testing indirect and spurious causal effects. In practice, detecting these effects is a complicated task, since the auxiliary variables that transmit/induce...
