The difficulty of short-selling stocks in the Chinese markets conforms to the assumption of the 'Differences-of-Opinion' theory and therefore, provides an empirical framework for testing the theory. The results show evidence supporting the theory: heavier trading predicts a more negatively...

We investigate the asymmetric risk-return relationship in a time-varying beta CAPM. A state space model is established and estimated by the Adaptive Least Squares with Kalman foundations proposed by McCulloch. Using S&P 500 daily data from 1987:11-2003:12, we find a positive risk-return...

Empirical evidence showing significant effects of local factors on international equity returns while failing to find significant effects from global systematic risk seems counter-intuitive in today's integrated world markets. This paper uses the conditional second moments estimated from an...

This paper uses the short-run restrictions implied by a simple aggregate demand-aggregate supply model as an aid in identifying structural shocks. Combined with the Blanchard-Quah restriction, it allows estimation of the slope of the aggregate supply curve, the variances of structural demand and...

Previous research indicates that the price-output correlation is time varying. This paper therefore estimates a vector autoregression (VAR) model with a bivariate generalized autoregressive conditional heteroskedasticity (GARCH) error process to obtain quarterly estimates of the price-output...

It is generally agreed that the price-output correlation in the United States was positive prior to the Second World War, but became negative during the postwar period (at least by 1972). This paper offers evidence that the price-output correlation changed signs because of a decrease in the...
