Suppose that world nominal interest rates to increase by 10 percent, i.e. = 0.10. Suppose the economy goes back to steady state in just one period. Let B = 0.90, o = 2,4 = 1, 0 = 4, and k = 0.25. For an open economy one with v = = 0.5, consider two possible scenarios: (i) the interest rates at the local economy are stuck at the zero lower = bound and do not respond t = 0 and (ii) the interest rates increase by 5 % t = 0.05. For both scenarios, calculate t, t and . Explain your results briefly. t1 2. World Interest Rates Going Up. Marks: 4.
