Solutions

Expert Solution

Since a recession is the time period of the economy in which the price level is quite low and the demand for goods and services is also very low. So the unemployment rate is very high, therefore the purchasing power is very low. Therefore there is a need for government intervention by increasing its expenditure and decreasing tax rate. So that aggregate demand could increase.

Since equilibrium is determined by the equality of aggregate demand and aggregate supply. So initial equilibrium price is P and quantity of real GDP is Yp that is potential real GDP. But when aggregate demand decreases, then the AD curve shifts leftward, so the price level decreases to P1 and real GDP decreases to Y1. Since aggregate demand has decreased and price level has decreased, so it is a situation of recession.

The potential real GDP remains same because there is no decrease in the production potential.

Hence option d is the correct answer.

Distinguish between demand-pull inflation and cost-push inflation and then use an AD-AS (aggregate demand/aggregate supply) model to illustrate the theoretical effects of these two types of inflation on the price level (P), employment (L) and economic growth (real GDP) in the short run. Now identify the various factors that have contributed towards demand-pull inflation and cost-push inflation in South Africa and critically analyse whether they are consistent with the predictions of the AD-AS model.
