A method for using panel data to evaluate growth theories is formulated. This method enables endogenous growth models predicting that countries have different trend growth rates to be tested against exogenous growth models predicting that countries have parallel growth paths. This method is...

Using two simple stochastic growth models that nest both exogenous and endogenous growth, this paper shows that money should not be neutral in the long run if it is not neutral in the short run and if growth is endogenous. By contrast, if growth is exogenous, money should be neutral in the long...

We investigate confidence intervals and inference for the instrumental variables model with weak instruments. Wald-based confidence intervals for a structural parameter perform poorly in that the probability they reject the null is far greater than their nominal size. We show that the preactice...

A decade ago Fama and French (1998) estimated that 40% variations in stock returns was predictable over horizons of 3-5 years, which they attributed to a mean reverting stationary component in prices. While it has been clear that the Depression and war years exert a strong influence on these...
