In this chapter we show that all the known estimators of the coefficients of econometric models are inconsistent if their coefficients and error terms are not unique. In their stead, we present models having unique coefficients and error terms, with specific applicability to the analyses of...

As every econometrician knows, in a regression with one regressor, the dependent and explanatory variables may be spuriously correlated if they may have been affected by some third variable, a common cause. In a highly regarded article, Granger and Newbold (1974) were not concerned with this...

Thirty-five years ago, J. W. Pratt and Robert Schlaifer published a critique of then ruling econometric techniques. Introducing a distinction between factors and concomitants in regressions, they determined that a “condition for consistent estimation stated in virtually every book on...

The conclusions of a logically consistent economic theory which strictly adheres to Aristotle's axioms of logic are factually true if its sufficient conditions are all factually true. Alternatively, if a conclusion of such a theory is false, then at least one of its assumptions is false....

Among the many troublesome econometric relationships, the demand for money has proved especially recalcitrant, as evidenced by a long history of tinkering with basic specifications, always in response to some recent perceived forecast failure. The shortcomings of this approach and an alternative...
