The needs for international monetary reserves,exchange rate flexibility,and joining a currency area

Summary The needs for reserves, exchange rate flexibility and monetary policy are derived, the need being the result of an optimization problem. The level of domestic production, its variance and that of the domestic price level have been chosen as criteria of the benefits and costs. The effectiveness and costs of balance of payments adjustment, which appear to be co-determinants of the needs, are expressed in the parameters of an economic model. This shows that the need for reserves displays a one-to-one relation to quantities of the demand for money and to the balance of payments disturbance. Only the latter is a meaningful criterion for joining a currency area. Helpful comments by Mr. G. J. Lanjouw and a referee are acknowledged.

Taxes, clientele effect of dividend and risk, return linearity

This paper extends the equivalence relationship between risk/return linearity and portfolio efficiency as derived in Roll (1977) to the case where there is differential taxation affecting investors optimal portfolio choice. Following the formulation of Brennan (1970a), the fundamental linearity relationship is derived which raises serious doubts to the testability of the extendedCAPM that accounts for the effect of differential taxation. Finally by aggregating other imperfections as well as differential taxation into a dividend yield constraint, a different version of theCAPM is derived which offers alternative interpretations of the existing empirical results on the subject.     

Similarities between conflict and cooperation in the marketing channel

This article examines the relationship between two causes of conflict: domain dissensus and perceptual incongruity, and the levels of conflict and cooperation within a marketing channel dyad. Utilizing a national sample of food broker-food wholesaler dyads, four hypotheses were tested—two relating domain dissensus and two relating perceptual incongruity to conflict/cooperation. Results indicated no significant relationship between either perceptual incongruities or domain dissensus and the level of conflict found in the dyad, while a significant negative relationship was found between both perceptual incongruities and domain dissensus and the level of cooperation in the dyad.
