Define the concept of equilibrium in the simple expenditure model we developed in class. Now, explain what signal in spending will tell us that the economy is not in equilibrium? Lastly, assume that we find that actual Y is greater than equilibrium Y, Ye thus actual current Y>Ye. Explain the reaction by firms to this situation and what you expect to happen to the actual level of Y because of this corporate reaction. Show the graph of the initial situation and the resulting change in Y due to the corporate reaction.

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. a. If household wealth falls by 5 percent because of declining house values, and the real interest rate falls by 3 percentage points, in what direction and by how much will the aggregate demand curve initially shift at each price level?
