The total money supply M is the sum of two components: bank deposits D and cash holdings C, which we assume to bear a constant ratio C/D = c, 0 < c < 1. The high-powered money H is defined as the sum of cash holdings held by the public and the reserves R held by the banks. Bank reserves are a fraction of bank deposits, determined by the reserve ratio r, 0 <r < 1. COMALEH a) Express the money supply M as a function of high-powered money H (10 points). b) Would an increase in the reserve ratio r raise or lower the money supply (10 points)? c) How would an increase in the cash-deposit ratio c affect the money supply (5 points)? Let the demand and supply functions for a commodity be Qa= D(P, Yo) (Dp < 0; Dy > 0) Qs = S(P,To) (Sp<0; ST > 0) Where Yo is income and To is the tax on commodity.
