Assume that the economy of Valoria is currently operating in short-run equilibrium with an actual unemployment rate of 3% and a natural rate of unemployment of 5%.

(a) Draw a correctly labeled graph of the aggregate demand, short-run aggregate supply, and long-run aggregate supply curves for Valoria, and show each of the following:
(i) The current equilibrium real output and price level, labeled \(Y_1\) and \(\text{PL}_1\), respectively
(ii) The full-employment output, labeled \(Y_F\)

(b) Assume the marginal propensity to save (MPS) in Valoria is 0.2, and the government decreases government spending by $40 billion to address the output gap.
(i) Calculate the maximum change in aggregate demand resulting from this change in government spending. Show your work.
(ii) Show the short-run effect of the decrease in government spending on your graph in part (a), labeling the new equilibrium real output and price level \(Y_2\) and \(\text{PL}_2\), respectively.

(c) Assume instead that policymakers take no policy action to close the output gap. Explain how Valoria's economy will adjust to full employment in the long run.

(d) Assume instead that Valoria's central bank decides to use monetary policy to address the inflationary gap. Assuming the banking system in Valoria operates with ample reserves, identify a specific monetary policy action the central bank would take.

(e) Draw a correctly labeled graph of the reserve market in Valoria, and show the effect of the monetary policy action identified in part (d) on the policy rate.

(f) Based on the change in the policy rate shown on your graph in part (e), how would each of the following be affected in Valoria in the short run?
(i) The price of previously issued bonds
(ii) Real gross domestic product (Real GDP). Explain.

Worked solution

(a)
(i) The graph must show a downward-sloping aggregate demand (AD) curve and an upward-sloping short-run aggregate supply (SRAS) curve intersecting to determine the short-run equilibrium output \(Y_1\) on the horizontal axis and price level \(\text{PL}_1\) on the vertical axis.
(ii) The long-run aggregate supply (LRAS) curve is a vertical line located to the left of \(Y_1\) (since actual unemployment of 3% is below the natural rate of 5%, indicating an inflationary gap), labeled \(Y_F\).

(b)
(i) The government spending multiplier is:
\[ \text{Multiplier} = \frac{1}{\text{MPS}} = \frac{1}{0.2} = 5 \]
\[ \Delta \text{AD} = \Delta G \times \text{Multiplier} = -\$40\text{ billion} \times 5 = -\$200\text{ billion} \]
The maximum change in aggregate demand is a decrease of $200 billion (or \(-\$200\text{ billion}\)).
(ii) On the graph in part (a), the AD curve shifts to the left (labeled \(\text{AD}_2\)), resulting in a lower equilibrium price level \(\text{PL}_2\) and a lower equilibrium real output \(Y_2\).

(c) In the long run without government intervention, the low unemployment rate creates a shortage of labor, putting upward pressure on nominal wages and other input prices (as well as inflationary expectations). As production costs rise, the short-run aggregate supply (SRAS) curve shifts to the left until output returns to the full-employment level \(Y_F\) at a higher price level.

(d) In an ample-reserves regime, the central bank would increase its administered interest rates (specifically, increase the interest rate on reserve balances / interest on reserves).

(e) The reserve market graph shows the policy rate on the vertical axis and the quantity of reserves on the horizontal axis. The demand curve for reserves is downward-sloping at low rates and becomes horizontal at the administered rate (interest on reserves). The supply curve of reserves is vertical and intersects the demand curve on its horizontal segment (the ample-reserves region). An increase in the administered rate shifts the horizontal portion of the demand curve upward, resulting in an increase in the equilibrium policy rate from \(\text{PR}_1\) to \(\text{PR}_2\).

(f)
(i) The price of previously issued bonds will decrease (due to the inverse relationship between interest rates and bond prices).
(ii) Real GDP will decrease. An increase in the policy rate raises short-term nominal and real interest rates, increasing borrowing costs. This decreases interest-sensitive private spending (consumption and gross investment), shifting the aggregate demand curve leftward and lowering equilibrium real output (real GDP).

Marking scheme

Part (a): 2 points
- 1 point for drawing a correctly labeled aggregate demand–aggregate supply graph showing \(\text{PL}_1\) and \(Y_1\) at the intersection of AD and SRAS.
- 1 point for showing a vertical long-run aggregate supply (LRAS) curve positioned to the left of \(Y_1\) and labeled \(Y_F\).

Part (b): 2 points
- 1 point for correctly calculating the maximum change in aggregate demand as \(-\$200\text{ billion}\) (or a decrease of $200 billion) and showing valid work: \(\text{Multiplier} = 1/0.2 = 5\) and \(\Delta \text{AD} = -40 \times 5 = -200\).
- 1 point for showing a leftward shift of the AD curve on the graph from part (a), resulting in a decrease in the price level to \(\text{PL}_2\) and a decrease in real output to \(Y_2\).

Part (c): 1 point
- 1 point for explaining that nominal wages (or input prices / inflationary expectations) will increase, causing the SRAS curve to shift left / decrease until real output returns to full employment.

Part (d): 1 point
- 1 point for stating that the central bank would increase its administered interest rates (or increase the interest on reserves / IORB rate).

Part (e): 2 points
- 1 point for drawing a correctly labeled graph of the reserve market showing a vertical supply curve intersecting the flat/horizontal region of the demand for reserves curve.
- 1 point for showing an upward shift of the administered rate (or horizontal portion of the reserve demand curve), leading to a higher policy rate.

Part (f): 2 points
- 1 point for stating that the price of previously issued bonds will decrease.
- 1 point for stating that real GDP will decrease AND explaining that the increase in interest rates reduces interest-sensitive spending (consumption or investment), causing aggregate demand to decrease.
Question 2 · free_response

The table below shows the quantities and prices of the goods in a typical consumer basket in the country of Veridia for Year 1 and Year 2. Assume Year 1 is the base year.

$$\begin{array}{|l|c|c|c|}
\hline
\text{Good} & \text{Basket Quantity} & \text{Year 1 Price} & \text{Year 2 Price} \\
\hline
\text{Bread} & 50 & \$2 & \$3 \\
\hline
\text{Energy} & 20 & \$5 & \$6 \\
\hline
\end{array}$$

(a) Calculate the cost of the market basket in Year 2. Show your work.

(b) Calculate the Consumer Price Index (CPI) for Year 2. Show your work.

(c) What was the rate of inflation from Year 1 to Year 2?

(d) Assume a worker received an 8% increase in nominal salary between Year 1 and Year 2. Did the worker's real wage increase, decrease, or remain the same? Explain using numbers.

(e) Suppose lenders and borrowers had expected an inflation rate of 40% when issuing fixed-rate loans between Year 1 and Year 2. Are commercial lenders better off, worse off, or unaffected by the actual inflation rate? Explain.
Show answer & marking scheme

Worked solution

(a) Cost of the basket in Year 2:
$$\text{Cost} = (50 \times \$3) + (20 \times \$6) = \$150 + \$120 = \$270$$

(b) First, compute the cost of the basket in the base year (Year 1):
$$\text{Cost}_{\text{Year 1}} = (50 \times \$2) + (20 \times \$5) = \$100 + \$100 = \$200$$
Then calculate the CPI for Year 2:
$$\text{CPI}_{\text{Year 2}} = \left( \frac{\text{Cost of Basket in Year 2}}{\text{Cost of Basket in Base Year}} \right) \times 100 = \left( \frac{\$270}{\$200} \right) \times 100 = 135$$

(c) The inflation rate is the percentage change in the CPI from the base year value of 100 to 135:
$$\text{Inflation Rate} = \left( \frac{135 - 100}{100} \right) \times 100 = 35\%$$

(d) The worker's real wage decreased because the nominal wage grew by 8%, which is less than the inflation rate of 35% (approximate change in real wage = $8\% - 35\% = -27\%$).

(e) Commercial lenders are better off because the actual inflation rate of 35% was lower than the expected inflation rate of 40%, which means lenders received a higher real return (real interest rate) on their fixed-rate loans than anticipated.

Marking scheme

(a) 1 point for calculating the cost of the market basket in Year 2 as $270 and showing correct work: $(50 \times 3) + (20 \times 6) = $270$.

(b) 1 point for calculating the CPI in Year 2 as 135 and showing correct work: $($270 / $200) \times 100 = 135$.

(c) 1 point for stating that the inflation rate is 35%.

(d) 1 point for stating that the real wage decreased AND explaining that the nominal wage increased by less than the inflation rate ($8\% < 35\%$).

(e) 1 point for stating that lenders are better off AND explaining that the actual inflation rate was less than expected ($35\% < 40\%$), meaning the real interest rate earned was higher than expected.

Assume that Arcadia currently has a balanced current account and capital and financial account (CFA).

(a) Suppose the real interest rate in Arcadia increases relative to the real interest rate in the rest of the world. What will happen to the flow of financial capital into Arcadia?

(b) Assume Arcadia and Ruritania are trading partners with flexible exchange rates. Arcadia's currency is the arc (ARC) and Ruritania's currency is the peso (RUP). Draw a correctly labeled graph of the foreign exchange market for the arc, and show the effect of the change in financial capital flows identified in part (a) on the equilibrium exchange rate (RUP/ARC).

(c) Based on the change in the international value of the arc shown on your graph in part (b), what will happen to Arcadia's net exports? Explain.

(d) How will the change in net exports identified in part (c) affect Arcadia's current account (CA) balance?
Show answer & marking scheme

Worked solution

(a) Higher relative real interest rates in Arcadia offer a higher rate of return on Arcadian financial assets, which will cause financial capital inflows into Arcadia to increase.

(b) A correctly labeled foreign exchange graph for the arc must have:
- Vertical axis: Price of ARC in terms of RUP (e.g., RUP/ARC or Exchange Rate)
- Horizontal axis: Quantity of ARC
- Downward-sloping demand curve for ARC (\(D_{\text{ARC}}\)) and upward-sloping supply curve of ARC (\(S_{\text{ARC}}\))
- An outward/rightward shift in the demand curve for the arc (\(D_{\text{ARC1}}\) to \(D_{\text{ARC2}}\)) (and/or a leftward shift in the supply curve of ARC), leading to an increase in the equilibrium exchange rate from \(e_1\) to \(e_2\) (appreciation of the ARC).

(c) Arcadia's net exports will decrease. Because the currency appreciated, domestic goods become relatively more expensive to foreign buyers (decreasing exports) and foreign goods become relatively less expensive to domestic buyers (increasing imports), leading to a reduction in net exports (\(NX = X - M\)).

(d) Arcadia's current account (CA) will move into deficit (or decrease/become negative) as a result of the decrease in net exports.

Marking scheme

Total: 5 points

(b) Assume Arcadia and Ruritania are trading partners with flexible exchange rates. Arcadia's currency is the arc (ARC) and Ruritania's currency is the peso (RUP). Draw a correctly labeled graph of the foreign exchange market for the arc, and show the effect of the change in financial capital flows identified in part (a) on the equilibrium exchange rate (RUP/ARC).

(c) Based on the change in the international value of the arc shown on your graph in part (b), what will happen to Arcadia's net exports? Explain.

(d) How will the change in net exports identified in part (c) affect Arcadia's current account (CA) balance?
Show answer & marking scheme

Worked solution

(a) Higher relative real interest rates in Arcadia offer a higher rate of return on Arcadian financial assets, which will cause financial capital inflows into Arcadia to increase.

(b) A correctly labeled foreign exchange graph for the arc must have:
- Vertical axis: Price of ARC in terms of RUP (e.g., RUP/ARC or Exchange Rate)
- Horizontal axis: Quantity of ARC
- Downward-sloping demand curve for ARC (\(D_{\text{ARC}}\)) and upward-sloping supply curve of ARC (\(S_{\text{ARC}}\))
- An outward/rightward shift in the demand curve for the arc (\(D_{\text{ARC1}}\) to \(D_{\text{ARC2}}\)) (and/or a leftward shift in the supply curve of ARC), leading to an increase in the equilibrium exchange rate from \(e_1\) to \(e_2\) (appreciation of the ARC).

(c) Arcadia's net exports will decrease. Because the currency appreciated, domestic goods become relatively more expensive to foreign buyers (decreasing exports) and foreign goods become relatively less expensive to domestic buyers (increasing imports), leading to a reduction in net exports (\(NX = X - M\)).

(d) Arcadia's current account (CA) will move into deficit (or decrease/become negative) as a result of the decrease in net exports.

Assume that Arcadia currently has a balanced current account and capital and financial account (CFA).

(a) Suppose the real interest rate in Arcadia increases relative to the real interest rate in the rest of the world. What will happen to the flow of financial capital into Arcadia?

(b) Assume Arcadia and Ruritania are trading partners with flexible exchange rates. Arcadia's currency is the arc (ARC) and Ruritania's currency is the peso (RUP). Draw a correctly labeled graph of the foreign exchange market for the arc, and show the effect of the change in financial capital flows identified in part (a) on the equilibrium exchange rate (RUP/ARC).

(c) Based on the change in the international value of the arc shown on your graph in part (b), what will happen to Arcadia's net exports? Explain.

(d) How will the change in net exports identified in part (c) affect Arcadia's current account (CA) balance?
Show answer & marking scheme

Worked solution

(a) Higher relative real interest rates in Arcadia offer a higher rate of return on Arcadian financial assets, which will cause financial capital inflows into Arcadia to increase.

(b) A correctly labeled foreign exchange graph for the arc must have:
- Vertical axis: Price of ARC in terms of RUP (e.g., RUP/ARC or Exchange Rate)
- Horizontal axis: Quantity of ARC
- Downward-sloping demand curve for ARC (\(D_{\text{ARC}}\)) and upward-sloping supply curve of ARC (\(S_{\text{ARC}}\))
- An outward/rightward shift in the demand curve for the arc (\(D_{\text{ARC1}}\) to \(D_{\text{ARC2}}\)) (and/or a leftward shift in the supply curve of ARC), leading to an increase in the equilibrium exchange rate from \(e_1\) to \(e_2\) (appreciation of the ARC).

(c) Arcadia's net exports will decrease. Because the currency appreciated, domestic goods become relatively more expensive to foreign buyers (decreasing exports) and foreign goods become relatively less expensive to domestic buyers (increasing imports), leading to a reduction in net exports (\(NX = X - M\)).

(d) Arcadia's current account (CA) will move into deficit (or decrease/become negative) as a result of the decrease in net exports.

- Vertical axis: Price of ARC in terms of RUP (e.g., RUP/ARC or Exchange Rate)
- Horizontal axis: Quantity of ARC
- Downward-sloping demand curve for ARC (\(D_{\text{ARC}}\)) and upward-sloping supply curve of ARC (\(S_{\text{ARC}}\))
- An outward/rightward shift in the demand curve for the arc (\(D_{\text{ARC1}}\) to \(D_{\text{ARC2}}\)) (and/or a leftward shift in the supply curve of ARC), leading to an increase in the equilibrium exchange rate from \(e_1\) to \(e_2\) (appreciation of the ARC).

(c) Arcadia's net exports will decrease. Because the currency appreciated, domestic goods become relatively more expensive to foreign buyers (decreasing exports) and foreign goods become relatively less expensive to domestic buyers (increasing imports), leading to a reduction in net exports (\(NX = X - M\)).

(d) Arcadia's current account (CA) will move into deficit (or decrease/become negative) as a result of the decrease in net exports.

Assume that Arcadia currently has a balanced current account and capital and financial account (CFA).

(a) Suppose the real interest rate in Arcadia increases relative to the real interest rate in the rest of the world. What will happen to the flow of financial capital into Arcadia?

(b) Assume Arcadia and Ruritania are trading partners with flexible exchange rates. Arcadia's currency is the arc (ARC) and Ruritania's currency is the peso (RUP). Draw a correctly labeled graph of the foreign exchange market for the arc, and show the effect of the change in financial capital flows identified in part (a) on the equilibrium exchange rate (RUP/ARC).

(c) Based on the change in the international value of the arc shown on your graph in part (b), what will happen to Arcadia's net exports? Explain.

(d) How will the change in net exports identified in part (c) affect Arcadia's current account (CA) balance?
