This paper provides two alternative estimation and testing procedures of a representative-agent model of asset pricing which relies on a particular parametrization of non-expected-utility preferences. The first is based on maximum-likelihood estimates, supplemented with an explicit model of time...

Recent empirical work indicates that, in a variety of financial markets, both conditional expectations and conditional variances of returns are time- varying. The purpose of this paper is to determine whether these joint fluctuations of conditional first and second moments are consistent with...

This paper attempts to determine whether the fluctuations of conditional first and second moments--which are observed for many assets--are consistent with the Sharpe-Lintner-Mossin capital asset pricing model. The authors test the mean-variance model under several different assumptions about the...
