Consider the IS-PC-MR model with adaptive expectations. Suppose that the central bank minimized the following loss function L = (Prye}: + (m arT subject to the Phillips Curve 11': = It's-I + (\"Pr ye) where ye = 4, and II: = 3. Suppose that in Time 0, in addition to ination targeting, the CB starts targeting output at yH =4+(Z/2.5). The highest level of output this economy will reach during the transition to the new equilibrium is _(a)_. In Time 2, the level of ination will be _{b)_ and the level of output will be _(c)_ .The magnitude of the ination bias will be _{d)_ percent. . Suppose the home economy begins in trade balance with exports equal to imports, which are equal to 100. The elasticity of demand for exports is Z! 10 and for imports is 0.50. Consider the implications of a 1% rise in competitiveness arising, for example, from a 1% rise in foreign relative to domestic prices. If the elasticity of demand for imports is 0.50, then the balance of trade (BT) will _(a) (13) improvement in the BT is (c) , reaching the value of . The lowest value of the elasticity of demand for imports that ensures an (Hint: choose your nonnumerical answers among the following options: "improve", "deteriorate", "remain unchanged")
