We obtain semiparametric efficiency bounds for the estimation of a location parameter in a time series model where the innovations are stationary and ergodic, conditionally symmetric martingale differences but otherwise possess general dependence and distributions of unknown form. We then...

In the recent SVAR literature, the liquidity effect has been studied by imposing a variety of identifying restrictions required under the assumption that the SVAR fundamental disturbances are homoscedastic. Using typical SVAR processes, we first show that this assumption is not supported by the...

This paper investigates the testable restrictions on the time-series behavior of equity premia implied by a representative agent model whose state- and time-non separable preferences are subject to taste shocks. The model nests state- and time-separable preferences with and without taste shocks...
