2. Draw an AE diagram and illustrate and explain what occurs when actual output is more than desired expenditures

Expert Solution

AE is the planned/desired expenditure of the economy. In the AE graph we draw a 45 degree line we represents the output production line (or the break even line when production equals demand - Y=AE). The AE line has a positive intercept because of positive autonomous consumption, investment and governement expenditure. While the slope of the AE line is given by the mpc. The point where Y line intersects the desired expenditure line AE is the equilibrium level where output Y equals AE - this is at e.

Now when actual output is more than desired expenditure, it means the economy is producing above what is demanded (above potential). This situation is indicated at output level of Y1. At Y1, the actual output is at b point while the desired expenditure is at a. The gap ab repesents the surplus or the excess supply. This situation arises because planned investment was more than desired investment which leads to a positive rise in inventory investment. So for equilibrium to occur again, firms must decrease their investment levels until Y again equals AE.

In the expenditure–output or Keynesian cross model, the equilibrium occurs where the aggregate expenditure line (AE line) crosses the 45° line. Given algebraic equations for two lines, the point where they cross can be calculated easily. Imagine an economy with the following characteristics. Y = Real GDP or national income C = Consumption = 50 + 0.8Y I = Investment = 200 G = Government spending = 100 Calculate the equilibrium level of income (Y) Suppose G increases to 125...

What are whales and horses adapted for? 1. Illuminate (investigate, illustrate {draw, diagram, print}, describe, and explain) what scientists have discovered regarding the adaptations present in the cranial anatomy of baleen whales including: 1. the very large cranium with “telescoped” cranial and facial bones 2. Adaptations for aquatic breathing and sound generation (nasal opening (blowhole), lungs, air passages, phonic lips, etc.) 3. Adaptations for aquatic hearing (high frequency clicks involved in echolocation (toothed whales only), infrasound (ultra low frequency sound...

1. Draw an exposure diagram to illustrate a firm’s exposure to interest rate risk if the firm is going to borrow $10m six months from today. Assume the loan will be a one-year loan with all interest paid at the end of the year. Graph the relation between the firms interest costs and interest rates. Also graph the relation between the firm’s profit and interest rates (assuming that higher interest costs cannot be passed on the consumers). 2.Draw an exposure...
