Long-Run Real Interest Rate and Supply-Side Equilibrium
In the long run, the real interest rate is not a discretionary policy choice for a central bank. Instead, it is endogenously determined by the requirements of the economy's supply side. To maintain a stable rate of inflation, the real interest rate must be at a level that keeps aggregate demand aligned with the economy's equilibrium output. Therefore, the central bank's task is to set its nominal policy rate to achieve this specific, equilibrium real interest rate.

Long-Run Real Interest Rate and Supply-Side Equilibrium
An economy is in a stable state where unemployment is at its supply-side equilibrium level and the actual inflation rate has been constant at 2% for several years. Suddenly, due to a credible announcement from the central bank, both firms and workers revise their inflation expectations for the upcoming year to 4%. Assuming aggregate demand in the economy remains just sufficient to keep the unemployment rate at its initial equilibrium level, what is the most likely outcome for the actual inflation rate in the next period?
Analyzing Economic Stability
Conditions for Stable Inflation
In an economy experiencing a stable inflationary equilibrium, a persistent positive bargaining gap is necessary to ensure that the actual rate of inflation remains constant and positive.
Match each economic state on the left with its corresponding implication for the bargaining gap and inflation on the right.
An economy is in a state of stable equilibrium with a constant, positive rate of inflation. Arrange the following statements to describe the logical sequence of events that occurs within a single period (e.g., one year) to maintain this equilibrium.
The Mechanics of Stable Inflationary Equilibrium
In an economy at a stable inflationary equilibrium, both nominal wages and prices are rising at the same constant rate. This implies that the ________ wage must be constant, corresponding to the level determined by the intersection of the wage-setting and price-setting curves.
An economy is described as being in a stable inflationary equilibrium. Which of the following statements would be inconsistent with this description?

Central Bank's Short-Run Control over the Real Interest Rate
A central bank governor makes the following statement: "To ensure robust long-term prosperity, our new permanent policy will be to hold the real interest rate at 0.5%, which is significantly below the rate that has historically balanced our economy. This will guarantee higher investment and output indefinitely." Assuming the underlying productive capacity (the supply side) of the economy does not change, what is the most significant flaw in this plan?

The Limits of Long-Run Monetary Policy
In the long run, a central bank can permanently stimulate economic output above its equilibrium level by consistently setting its policy rate to maintain a real interest rate below the level required for supply-side equilibrium.
