We use the Granger causality concept to find the existence of such a relationship. The chapter presents the results of two separate bivariate analyses: one involving money and income, and the other involving money and exchange rates. A notable result to come out of the chapter is that there is no causality relationship between them.enCausality relationship between money, income, price, and exchange rates in a small open economyBook Chapter
