Country and Industry Equity Risk Premia in the Euro Area: An Intertemporal Approach
ثبت نشده
چکیده
This paper provides new evidence on the dynamics of equity risk premia in euro area stock markets across country and industry portfolios. We develop and estimate a conditional intertemporal CAPM where returns on aggregate euro area, country and industry portfolios depend on the market risk as well as on the risk that the investment opportunity set changes over time. Prices of risks are time-varying, according to a Kalman lter approach. We nd that both market and intertemporal risks are signi cantly priced. When we include country and industry-speci c risk factors they turn out to be not signi cantly priced for most industries, suggesting that euro area equity markets are well integrated. Overall, the analysis indicates that omitting the intertemporal factor leads to mispricing and misleading conclusions regarding the degree of nancial integration across sectors and countries. Keywords: conditional asset pricing, intertemporal risk, nancial integration, multivariate GARCH, Kalman lter JEL classi cation: G12, F37, C32

Equilibrium asset pricing with time - varying pessimism
We present a flexible analytical framework that incorporates the equilibrium impact of a (possibly state dependent) sentiment for pessimism in continuous time intertemporal asset pricing. State dependent pessimism comes from a state dependent confidence in the reference belief on equity returns dynamics and implies conservative optimal policies precisely in states where such confidence is low. ...

Sovereign risk premia have risen sharply in several European countries, contributed to increased credit spreads in the private sector. If monetary policy cannot offset these credit spreads because it is constrained by the zero lower bound, sovereign risk threatens macroeconomic stability: private-sector beliefs of a weakening economy may become self-fulfilling. In this paper, we put forward a t...
