illustrate graphically the effect of the following factors on the aggregate demand (AD) curve:
a) Interest-rate increases when the economy is good.
b) ringgit slumps due to the external factors.
What are three factors that help explain the slope of the aggregate demand curve? What is the most important factor? Why?
The graphs illustrate an initial equilibrium for the economy. Suppose that the government increases taxes.
Use the graphs to show the new positions of aggregate demand (AD), short-run aggregate supply (SRAS), and long-run
aggregate supply (LRAS) in both the short run and the long run, as well as the short-run and long-run equilibriums resulting
from this change. Then, indicate what happens to the price level and GDP in the short run and in the long run.

- A change in any factor that influences our planned expenditure other than the price level, brings a change in aggregate demand. One of these factors is fiscal and monetary policy.” In terms of the statement above, assess how fiscal and monetary policy influences aggregate expenditure in an economy.

Let us say the estimated equation for the economy's aggregate demand is Y=400 – 15P+ 8G And the estimated equation for the economy's aggregate supply is Y=5+11P-10W where Y is the country's real GDP, P is the price level (GDP deflator), G is government purchases of goods and services, and W is the index of wages. a.
