Short Answer Questions

Question 1: Consider the banking system.
a) Banks must hold reserves. Why? (2 marks)
Banks are required to hold reserves for a number of reasons primarily dictated by financial stability and regulatory requirements. Reserves are needed to meet customer withdrawals and to settle transactions between banks. Holding reserves ensures that banks do not run out of cash to satisfy customer demands, thereby maintaining trust in the banking system. Moreover, central banks impose reserve requirements to mitigate risks of bank runs, ensuring financial stability by preventing banks from overextending their lending capacity (Mishkin, 2018).
b) What are excess reserves? (1 mark)
Excess reserves refer to the amount of reserves that banks hold over and above the legally required minimum reserves mandated by the central bank. These funds can be loaned out to customers or invested, thereby creating opportunities for additional profits (Mishkin, 2018).
c) How are excess reserves calculated? (1 mark)
Excess reserves can be calculated using the formula:
\[ \text{Excess Reserves} = \text{Total Reserves} - \text{Required Reserves} \]
Where total reserves represent the sum of cash and deposits that banks retain, and required reserves are calculated as a percentage of total deposits as mandated by central bank regulations (Mishkin, 2018).
d) What is the significance of excess reserves? (2 marks)
Excess reserves serve multiple purposes. Firstly, they buffer banks against sudden increases in withdrawals, thereby enhancing liquidity and stability in the banking system (Bernanke & Gertler, 2001). Secondly, they provide banks with the opportunity to lend more, potentially boosting economic activity (Taylor, 2018). High levels of excess reserves can indicate that banks are being cautious in their lending practices, which could be a signal of economic uncertainty.

Question 2: The quantity theory of money
“The quantity theory of money (quantity equation) states than an increase in the money supply will lead to an equiproportionate increase in the price level.” Is this true or false? Explain. (4 marks)
This statement is true under certain assumptions of the Quantity Theory of Money, represented by the equation MV = PY, where M is the money supply, V is the velocity of money, P is the price level, and Y is the real output (Friedman, 1989). Specifically, if we assume that the velocity of money is constant and the economy is at full employment, an increase in money supply (M) will indeed lead to a proportional increase in the price level (P) over the long run (Friedman, 1989).
However, it does not account for short-term realities where changes in money supply can lead to variations in real output due to price stickiness and other factors (Blinder, 1997). Therefore, it is essential to note the context and time frame considered.

Question 3: Increased productivity
a) Using the aggregate demand/aggregate supply diagram, illustrate the effect of increased productivity the short-run (holding the LRAS curve constant). (1 mark)
Illustration: (Please insert a diagram here)
- X-axis: Quantity of Output
- Y-axis: Inflation Rate
- LRAS Curve: Vertical line representing long-run aggregate supply
- SRAS0: Original short-run aggregate supply curve
- AD: Aggregate demand curve
- SRAS1: Shifted short-run aggregate supply curve due to increase in productivity
Explain this adjustment process. (3 marks)
Increased productivity translates to lower production costs for firms, which shifts the Short-run Aggregate Supply (SRAS) curve to the right (from SRAS0 to SRAS1) as firms can produce more at lower prices. This results in a new equilibrium where output increases, and inflation rates may initially decrease or stabilize depending on the shift in demand. As the economy moves toward a new equilibrium, real GDP rises, potentially leading to lower unemployment in the short-run as firms require more labor to meet the increased output demands (Mankiw, 2021).

Question 4: High tariffs imposed by trading partners
a) Illustrate the short-run impact on your own economy in the diagram below. (1 mark)
Illustration: (Please insert a diagram here)
- X-axis: Quantity of Output
- Y-axis: Inflation Rate
- LRAS: Long-run aggregate supply
- SRAS0: Original short-run aggregate supply curve
- AD0: Original aggregate demand
- AD1: Aggregate demand curve shifts left due to reduced exports
b) What is the effect on the unemployment rate and the inflation rate in your nation in the short-run? (1 mark)
When high tariffs are imposed, exports decrease, leading to a leftward shift in the Aggregate Demand (AD) curve (from AD0 to AD1). This results in decreased output and higher unemployment rates as production contracts. Inflation rates might stabilize or drop slightly due to lower demand pressures in the economy (Krugman & Obstfeld, 2017).
c) Explain the adjustment process to a new long-run equilibrium (3 marks)
Over time, the economy will self-correct as the reduced demand prompts firms to lower prices to stimulate consumption and investment. The decreased inflation will also lead to lower interest rates, encouraging borrowing and spending. This can shift the AD curve back rightward until it reaches a new long-run equilibrium at a higher level of output in the long term due to potential investments in alternative sectors, ultimately restoring employment levels (Blanchard, 2017).
