The annual demand for and supply of pesos in the foreign exchange market are: Demand = 30, 000 - 6, 000e Supply = 22, 000 + 10, 000e where the nominal exchange rate is expressed as dollars per peso. The exchange rate is fixed at 0.6 dollars per peso. (a) Determine whether the peso is overvalued, undervalued or neither.
