Answer to Question 1

In the wake of a negative supply shock, policy makers may wish to implement expansionary policy to reverse the decline in economic activity. If this is understood as a temporary, emergency measure, rather than an abandonment of a commitment to price stability, expected inflation may decline even as aggregate demand is rising. However, under normal circumstances, any attempt to reduce unemployment and tolerate an increase in inflation will not be supported by credibility. On the contrary, such a policy must signal a lack of commitment to price stability; the loss of credibility confirms the illusory nature of the trade-off.

Answer to Question 2

In terms of output and expenditures, the equilibrium condition is Y = C + I + G + NX. Rearranging terms, Y - C - G = I + NX. For households, saving is Y - T - C. Government saving is T - G. National saving S = Y - T - C + T - G = Y - C - G. Substituting into the equilibrium equation, S = I + NX. Now, the combined saving by households and the government may be greater or less than investment, with the difference made up by a capital outflow (NX > 0 ) or capital inflow (NX < 0 ), respectively.
