This paper separates the validity of the specification of the fundamental stock price model from the implications of bubbles. The time-varying risk premium model (Poterba and Summers, 1986) is used to explicitly derive the misspecification component. We construct a state-space model and use...

This paper develops a shopping-time model in an open economy framework to motivate the specification of money demand. This microfoundations-of-money model allows me to choose which variables, and in what forms, should be used in the empirical money demand function. In particular, the model...

Previous research indicates that the price-output correlation is time varying. This paper therefore estimates a VAR with a bivariate GARCH error process to obtain a time series of quarterly estimates of the price-output correlation for the United States for the period 1876:4-1999:4. The...

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...

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

We extend the Fama-French three-factor model to include a risk factor that proxies for interest-rate risk faced by firms in an attempt to reduce the pricing errors that the three-factor model cannot explain. These pricing errors are observed especially in small size and low book-to-market ratio...

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...

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...
