What is the typical relationship among interest rates on three-month Treasury bills, long-term Canada bonds, and corporate bonds? Select the best answer: OA. All three rates are virtually exact representations of the rate of inflation. OB. They tend to move randomly and independently of each other. OC. They tend to move together over time with the corporate bond having the highest rate of interest. OD. They tend to move together over time with the three-month Treasury bill having the highest rate of interest.

The following graph depicts the short-run and long-run Phillips curves (SRPC and LRPC) for a hypothetical economy in long-run macroeconomic equilibrium at point A, where the natural unemployment rate is 6% and the current inflation rate is 8% per year.
Consider a version of the Phillips curve where a proportion of wages, 1 >> 0, are now indexed to the rate of inflation. In these labor contracts, nominal wages move one-for-one with the actual price level. The remaining proportion of wages, (1-2), are set on the basis of expected inflation: nt λnt (1) et+ (m+z)-aut (2) a. Suppose that лet=πt-1. Solve for the natural rate of unemployment (the rate such that t=t-1). Is the natural rate of unemployment different as a result of wage indexation? b. Re-write the Phillips curve in terms of the difference between чt and un using the value for un you calculated in (a). How does wage indexation impact the way changes in inflation respond to deviations of the unemployment rate from the natural rate? What is the intuition for this result?
QI Consider an economy where the impact of monetary policy can be summarised by the relation: Y = BM, where Y, M, B are output, the money supply and the monetary policy multiplier, respectively. It is not possible to adjust M to consistently hit an output target, say Y*, perfectly. This inability to hit the target generates the loss function, L (a function that describes the extent to which a target is missed): L=(Y - Y*)*. Let Y* = 3. Compute the choice of money supply M to minimise the above loss function when we are uncertain about the monetary policy multiplier. Specifically, ß can be either 0.5 or 1.5, with a 50% chance of it being either value.

16. Keynes (1936) argued that, from a policy perspective, everything that can be achieved by a nominal wage cut can be more effectively achieved through an appropriate monetary policy. (a) Does this statement hold in the deﬁcient-demand Keynesian model for a negative shock to (i) aggregate demand and (ii) aggregate labor productivity? (b) Does this statement hold in the new Keynesian model for a negative shock to (i) aggregate demand and (ii) aggregate labor productivity?
The text proposes the following model of expected inflation x = (1 - 0) x + 0,-1 What do we know about your process of the formation of expected inflation when 0 = 07 OA. Neither last year's inflation rate nor the long-run average inflation rate impact your view on this year's expected rate. OB. Last year's inflation rate will influence you to revise your estimates for this year's expected rate. OC. Regardless of what inflation was last year, you would expect it to be at the long-run average inflation rate this year. OD. Last year's inflation rate and the long-run average inflation rate have an equal impact on your view of this year's expected rate. What do we know about your process of the formation of expected inflation when 0-17 OA. Neither last year's inflation rate nor the long-run average inflation rate impact your view on this year's expected rate OB. Last year's inflation rate will be the only input for you to revise your estimates for this year's expected rate regardless of…
