Abstract:
This paper compares alternative estimates of systemic time-varying excess returns for the Irish pound and the Spanish peseta, against the German mark, since 1985. We make use of progressively more complex models, going from the GARCH in Mean specification, to the International Capital Asset Pricing model (ICAPM) with a time-varying "beta", to a general equilibrium Constant Relative Risk Aversion model (CRRA), with trivariate GARCH-M estimation. The results show significant relative risk aversion as well as significant volatility effects on redictable excess returns. The time-varying "beta" has also declined in the past five years for both Ireland and Spain.
