III. Critical thinking [3 pts]

(1) Yes, an economy could experience a recession while nominal GDP continues to grow if inflation is high enough. In a recession real GDP decreases. However, nominal GDP = real GDP × GDP price index / 100. Using the percent-change rule for products,

growth rate nominal GDP = growth rate real GDP + inflation rate.

So even if the growth rate of real GDP is negative, if the inflation rate is even larger, and positive, then nominal GDP will continue to grow.

(2) Country X and Country Y have exactly the same GDP. By definition, GDP equals the value of final goods and services produced annually in a country. So if that is equal in the two countries, then GDP is equal, regardless of education levels or life expectancies.
