Is an increase in aggregate demand in an economy always desirable?

An increase in aggregate demand is not always desirable, as it can lead to inflation if the economy is already operating at or near full capacity. While higher demand can stimulate economic growth and reduce unemployment in the short term, it may also result in rising prices and potential overheating of the economy. Additionally, if the increase in demand is driven by unsustainable factors, such as excessive credit or government spending, it could lead to long-term economic instability. Thus, the effects of increased aggregate demand depend on the economic context and underlying conditions.
