Economic and Accounting (Book) Rates of Return: Application of a Statistical Model

Abstract

Kay (1976), Ijiri (1979), Salamon (1982) and Kelly and Tippett (1991), for example, can be interpreted as extensions of Harcourt's seminal analysis, while Kay (1976), Salamon (1982, 1985) and Gordon and Hamer (1988) provide empirical evidence on the sustainability of basic propositions.

The economic return is estimated using three cash flow definitions. For all three, the accounting rate of return is significantly lower than the economic return. Further tests show the economic return to be inversely related to the accounting rate of return, although the relationship is weak. In addition, ‘...
