In the long run, the economy adjusts to the increase in aggregate demand. As the price level increases, the short-run AS curve shifts upward, from SRAS1 to SRAS2. This is because firms adjust their expectations of future inflation, and wages and other costs increase.
“Suppose the government of Hong Kong increases its expenditure on infrastructure projects. Using the AD-AS model, explain the effects of this increase in government expenditure on the level of real GDP and the price level in the short run and in the long run.”
In the short run, the economy moves from point A to point B. At point B, the level of real GDP increases from Y1 to Y2, and the price level increases from P1 to P2. This is because the increase in aggregate demand leads to a higher level of production and employment, causing the price level to rise.
In conclusion, HKCEE 2010 Econ Paper 2 Q2 requires students to apply their knowledge of macroeconomic concepts, specifically the AD-AS model, to analyze the effects of changes in aggregate demand on the economy. By understanding the short-run and long-run effects of an increase in government expenditure, students can develop a deeper appreciation of the complexities of macroeconomic policy and its impact on the economy.
