Marketing’s contribution to the strategy dialogue revisited

Conclusions The purpose of this commentary is to offer a different perspective on marketing’s contributions to the strategy dialogue and strategic management from that provided by Day. In this regard, the comment intends to supplement and complement his valuable insights. In closing, it is instructive to consider what is meant by strategy and consider the thoughts of Andrews (1983): It is part of the comprehensive concept of strategy that leaders of a company must be dedicated to the durable core of a company’s character ... while encouraging innovations that will bring about or respond to the changes taking place in its surroundings (p. 9). Another look at the very concept of strategy might provide marketing and strategic management scholars with the foundation upon which to build a substantive dialogue.     

THE RELATIONSHIP BETWEEN BEFORE- AND AFTER-TAX YIELDS ON FINANCIAL ASSETS

In this research, the traditional approximation that after-tax yields equal before-tax yields times one minus the tax rate is shown in general to be incorrect. The traditional relationship holds only for one-year assets and perpetuities when a single tax rate applies to both ordinary income and capital gains. For all other multiperiod assets, the correct relationship is much more complex and is a function of the statutory tax rates on ordinary income and capital gains, the holding period, the dividend growth rate for common stocks, and any premium or discount on bonds. The direction of bond price changes is related inversely to the direction of the tax rate changes, but the direction of common stock price changes is related ambiguously to the direction of tax rate changes.     

Predicting African military coups

Since independence the states of Black Africa have witnessed well over 40 successful military coups d'état—events which have commonly been interpreted as occurring in an essentially random and unpredictable manner. Surveying both current and past attempts at explanation and prediction the paper argues that more successful forecasts depend on a recognition that coups are not an homogeneous category and that motives for intervention exhibit clear temporal variations.
