13.1 13.1

13.2 13.2

13.3 13.3

13.4 13.4

Equation (13.1) is a standard money market equilibrium equation, with mt being the log-money supply, pt the log-price level, yt the log-output level, and it the interest rate. Equation (13.2) is the analogous equation for the Foreign country.1 Equation (13.3) is a purchasing power parity equation and Equation (13.4) is an interest rate parity equation. ψt is the deviation from uncovered interest rate parity (UIP).

Substituting Equations (13.1)–(13.3) into Equation (13.4) we obtain a first-order difference equation with a familiar solution

13.5 13.5
