Short-run asset approach to exchange rate Output Y is fixed Price level P is sticky Nominal (E) and real exchange rates (q) are proportional to each other, % E = % q Nominal (i) and real interest rate (r) are equal Nominal interest rate is flexible in the short run and can deviate from its long-run level to clear the money market

Short-run asset approach to exchange rate Exogenous variables : M, M*, P, P*, Y, Y*, E e , where E e = long-run equilibrium exchange rate Endogenous variables : i, i*, E Model (1) = L( i ) Y i = f ( M, P, Y ) MM Equil (2) = L( i* ) Y* i* = f ( M*, P*, Y* ) MM Equil (3) i = i* + FXM Equil

Money Market Equilibrium In the short-run it is the nominal interest rate, instead of the price level, that clears the money market. MM equil is achieved as consumers switch between money and bond to achieve their desired money holding

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
