Some alternative tests of forward exchange rates as predictors of future spot rates

The paper provides empirical analysis on the issue of forward premiums as predictors of future exchange depreciations. The need to specify an alternative to the null hypothesis, other than its complement is emphasized. Two such alternatives are considered: the random walk model and the possibility of excessive or insufficient exchange rate volatility to accord with the efficiency of exchange markets.     

The relationship between growth,profitability, and firm value

This research examined predictions drawn from value-based planning models. Results indicate that profitability and growth do influence shareholder value in the manner predicted; however, the relationships are conditional. This study also shows that, the market-to-book value of equity ratio and Tobin's q-ratio are theoretically and empirically, equivalent measures of value creation.     

Bursting bubbles: On the rationality of hyperinflations in optimizing models

It is well known that perfect foresight maximizing models frequently possess a continuum of equilibria. In some of these equilibria the price level is explosive even in models in which the money supply is constant. This paper shows that a sufficient condition to rule out these unstable paths is given by the assumption that there is a smallest non-zero unit of output.     

The marketing of hamburger buns: An improved model for prediction

The Spring 1974 issue of this Journal published a paper that presented a model for predicting sales of hamburger buns. This article evaluates the model on the bases of statistical reporting, model specification, and implications for production policy. In addition, using the same data used for the original model, an improved model is developed whereby there is a 50% increase in explained variance.     

The rent gradient for manufacturing

Rent gradients for manufacturing are estimated using actual rent and value figures for Cincinnati. Distance to the city center is found to be of no importance in explaining rent or value variations.
