GDP Growth with Mismatch Unemployment
A Special Administrative Region reports nominal GDP growth of 6.5% in a year, while the GDP deflator rises by 4.0%. The working-age population is unchanged, but the labour force participation rate rises from 61.0% to 62.5% as students and retirees re-enter the job market. Total employment rises by only 1.0%, mostly in construction jobs linked to a one-off airport expansion. At the same time, a large online retailer closes its local warehouse and 1,200 logistics workers lose their jobs; 700 have skills that do not match the new construction vacancies, and 500 are rehired after three months. Youth unemployment rises from 8% to 11%, while the headline unemployment rate rises from 3.2% to 4.0%. The government is considering a training subsidy and a temporary payroll tax cut. The central bank, which operates a linked exchange rate, is not considering an interest rate change.
1. Distinguish real GDP growth from nominal GDP growth and assess whether living standards have risen.

Nominal GDP growth of 6.5% includes both price and quantity changes. The GDP deflator rose by 4.0%, so real GDP growth is approximately 6.5% minus 4.0%, or 2.5%; using the ratio, 1.065 divided by 1.04 gives about 2.4%. The volume of output therefore grew by about 2.4%, not 6.5%.
Living standards depend on real GDP per capita, distribution, leisure, health, and environmental quality, not just total output. The working-age population is unchanged, but participation rose, so more people are looking for work. Employment grew by only 1.0%, less than real GDP, suggesting some productivity gain, but much of the growth comes from one-off airport construction that may not last. The rise in youth unemployment and the warehouse closure suggest that some households are worse off. Airport expansion may also create noise and congestion externalities. Real GDP growth of 2.4% is therefore not enough to conclude that living standards have risen for everyone.
2. Classify the unemployment arising from the warehouse closure and youth unemployment. Which policy is better targeted: training subsidy or payroll tax cut?
Read the worked answer
The 700 logistics workers whose skills do not match construction vacancies are structurally unemployed: there are jobs, but the workers lack the required skills or location. The 500 workers rehired after three months are frictionally unemployed, because their spell is short and linked to job search. Youth unemployment rising from 8% to 11% while participation rises is likely a mix of frictional school-to-work unemployment and structural lack of experience; it is not clearly demand-deficient because the headline rise is partly due to more people entering the labour force.
A payroll tax cut lowers the cost of hiring and could encourage firms to take on young or displaced workers quickly. But it is broad and may subsidise jobs that would have been created anyway. A training subsidy is better targeted at the 700 workers with skill mismatch and at youth who lack relevant training. Training takes time, so a combination is sensible: a temporary payroll tax cut for youth hiring plus a training subsidy for displaced logistics workers. If only one policy can be chosen, the training subsidy addresses the structural core more directly.
3. Explain why the central bank cannot use interest rates to reduce unemployment in this economy.
Read the worked answer
The economy operates a linked exchange rate, so the central bank's primary objective is to keep the exchange rate within its fixed band. If it cut interest rates independently to stimulate domestic demand, short-term capital would flow out in search of higher returns, putting downward pressure on the currency. The central bank would then have to sell foreign reserves and raise interest rates again to defend the peg. Monetary policy is therefore effectively imported from the anchor country rather than set for domestic conditions.
Because interest rates cannot be used to reduce unemployment, the government must rely on fiscal policy, such as the training subsidy or payroll tax cut, and on supply-side measures that improve matching between workers and vacancies. The linked exchange rate also means that the economy cannot use exchange-rate depreciation to boost export demand. This limits the policy toolkit and makes targeted labour-market measures more important.
