What is the effect of an increase in investment? When investment increases, O A. aggregate demand increases and income increases. The increase in income induces an increase in consumption expenditure so aggregate demand increases by more than the initial increase in investment O B. aggregate demand increases and aggregate supply increases investment O C. aggregate demand increases by an amount equal to the increase O D. aggregate supply increases. The increase in aggregate supply is greater than the increase in investment because capital increases, which increases potential GDP

Suppose that consumer spending initially rises by $5 billion for every 1 percent rise in household wealth and that investment spending initially rises by $20 billion for every 1 percentage point fall in the real interest rate. Also assume that the economy's multiplier is 4. If household wealth falls by 6 percent because of declining house values, and the real interest rate falls by 2 percentage points, in what direction and by how much will the aggregate demand curve initially shift at each price level? In what direction and by how much will it eventually shift?
