When federal government increases its government expenditure, (assuming other things equal), how does the aggregate demand change?
no change
aggregate demand increases and AD curve shifts to the right on the AD-AS diagram
aggregate demand increases and AD curve shifts to the left on the AD-AS diagram
aggregate demand decreases and AD curve shifts to the left on the AD-AS diagram
When the Fed increases money supply, how does it affect interest rate (r) and aggregate demand (AD)?
r falls and AD rises
r falls and AD falls
r rises and AD rises
r rises and AD falls
1. Aggregate demand increases and AD curve shifts to the right on the AD-AS diagram
All other things being constant, an increase in government expenditure will shift the aggregate demand curve to the right. Government expenditure is one of the components of aggregate demand. So increase in any of the components will increase the aggregate demand.
1. r falls and AD rises
Increase in money supply wil lower the interest rate. Borrowing becomes easier and investment increases. Due to increase in investment, aggregate demand increases.
