QUESTION 1 [25 MARKS]
Assume a macroeconomy producing only two distinct goods: A and B. Using 2022 as the
base year, note that all quantities are measured in thousands (All calculations should be
rounded to the nearest tenth).
Product Quantity (2022)
Quantity (2023)
Prices (2022)
Prices (2023)
A
2,000
2,100
$400
$400
B
1,000
1,040
$2,000
$2,100
a) Analyse the data provided to compute both the nominal and real GDP growth rates for
2022 and 2023 to elaborate on the distinction between the two measurements. [7]
b) Using the GDP deflator method, determine and interpret the inflation rate (rr) for the
year 2023. Provide a brief discussion on how the GDP deflator offers insights into
price level changes in the economy.
[6]
c) Given that the money supply (M) stood at $10,000 in 2023, derive the velocity of
money for the year. Offer an overview of the implications of the calculated velocity
for macroeconomic activity and monetary policy.
[6]
d) Anticipating a policy direction from .the Central Bank for a targeted inflation rate (rr)
of 2% in 2024 and assuming the real GDP growth rate mirrors that of 2023, deduce
the necessary money supply growth rate for achieving this target. Calculate the exact
volume of money the Central Bank needs to introduce into the economy and discuss
the potential economic ramifications of this monetary intervention.
[6]
QUESTION 2 [25 MARKS]
Examine the dynamics of the Mundell-Fleming model within the context of fluctuating world
interest rates.
a) Identify the underlying factors and conditions that might lead to a surge in the world
interest rate, considering the assumption that the world operates as a closed economy.
Discuss the immediate and long-term implications of rising world interest rates on
global trade and investment flows.
[7]
b) Utilise the Mundell-Fleming model to delve into the effects of an increasing world
interest rate on a small open economy with a floating exchange rate. Analyse the
impacts on:
• Aggregate income
• Exchange rate
• Trade balance
Incorporate graphical illustrations to enhance clarity and provide a comparative analysis
of the scenario before and after the surge in the world interest rate.
