A Model for the Ex-ante U.k. Stock Market Risk Premium
نویسندگان
چکیده
We propose a model for the aggregate stock market together with its dividend yield and earnings yield so that the ex-ante risk premium could be extracted in an unobserved component modelling framework. We posit the model as a linked stochastic differential equation system and the linking variable is the ex-ante risk premium. By hypothesising a realistic dynamic structure for the ex-ante risk premium, we demonstrate how such a system could be estimated as a filtering problem. As a practical demonstration of the methodology we apply the model to the U.K. stock market data.

The VAR model produces 'better' forecasts than the survey responses for turbulent periods such as 1981-1982 and 1984-1985. The VAR-generated expectations are t...
