Two aspects of statistical inference using variance-ratio statistics are studied, (1) the accuracy of asymptotic approximations in small samples and (2) the size distortion arising from searching over many horizons in deciding whether to reject a model. A joint test combining variance-ratio...

The Euler equations derived from intertemporal asset pricing models, together with the unconditional moments of asset returns, imply a lower bound on the volatility of the intertemporal marginal rate of substitution. This paper develops and implements statistical tests of these lower bound...

A Markov-switching model of postwar quarterly real GNP growth is used to examine the duration dependence of business cycles. It extends the Hamilton model and the duration-dependent model of Durland and McCurdy, and compares quite favorably to simpler models in out-of-sample forecasting. When an...

Recent empirical studies have found that stock returns contain substantial negative serial correlation at long horizons. We examine this finding with a series of Monte Carlo simulations in order to demonstrate that it is consistent with an equilibrium model of asset pricing. When investors...

This paper investigates the ability of a representative agent model with time separable utility to explain the mean vector and the covariance matrix of the risk free interest rate and the return to leveraged equity in the stock market. The paper generalizes the standard calibration methodology...

We study a Lucas asset pricing model that is standard in all respects representative agent's subjective beliefs about endowment growth are distorted. Using constant-relative-risk-aversion (CRRA) utility a CRRA coefficient below ten that exhibit, on average, excessive pessimism over expansions...

A recent article by Ben Bernanke (1984) tests the rational expectations-permanent income hypothesis using panel data on automobile expenditures. He finds no evidence refuting the hypothesis. This paper incorporates a threshold adjustment process into Bernanke's model. Estimations based on a...

This paper investigates the relationship between portfolio choice and labor income risk in the National Longitudinal Survey of Youth 1979 Cohort. Permanent income risk (variability of shocks to income that have permanent effect) significantly reduces the share of risky assets in the household's...
