چکیده
In "The Equity Risk Premium: A Pmxle', Mehra and Prescott (1985) developed an ArrowDebreu asset pricing model. They rejected it because it could not explain high enough equity risk premia. They concluded that only non-Arrow-Debreu models would solve this 'puzzle'. Here, I re-specify their model, capturing the effects of possible, though unlikely, market crashes. While maintaining their model's attractive features, this allows it to explain high equity risk premia and low risk-free returns. It ~1oes so with reasonable degrees of time preference and risk aversion, provided the crashes are plausibl;/severe and not too improbable.

Skewness Premium with Lévy Processes ∗
We study the skewness premium (SK) introduced by Bates (1991) in a general context using Lévy Processes. Under a symmetry condition Fajardo and Mordecki (2006) obtain that SK is given by the Bate’s x% rule. In this paper we study SK under the absence of that symmetry condition. More exactly, we derive sufficient conditions for SK to be positive, in terms of the characteristic triplet of the Lév...

متن کاملContribution of Somatic and Dendritic SK Channels in the Firing Rate of Deep Cerebellar Nuclei: Implication in Cerebellar Ataxia
