Desired consumption is Cd = 100 + 0.8Y - 500r - 0.5G, and desired investment is Id = 100 - 500r. Real money demand is Md/P = Y - 2000i. Other variables are πe = 0.05, G = 200, Y (Full output level) = 1000, and M = 2100. (a) Find the equilibrium values of the real interest rate, consumption, investment, and the price level. (b) Suppose the money supply increases to 2800. Find the equilibrium values of the real interest rate, consumption, investment, and the price level. (Assume that the expected inflation rate is unchanged.)

In a "dutch auction" for new stock, individual investors place bids for shares directly. each potential bidder indicates the price he or she is willing to pay and how many shares he or she will purchase at that price. the highest price that permits the company to sell all the shares it wants to sell is determined, and this is the "market clearing price." all bidders who specified this price or higher are allowed to purchase their shares at the market clearing price. true false

Jenny​ walters, who owns a real estate​ agency, bought an old house to use as her business office. she found that the ceiling was poorly insulated and that the heat loss could be cut significantly if six inches of foam insulation were installed. she estimated that with the​ insulation, she could cut the heating bill by​ $80 per month and the​ air-conditioning cost by​ $70 per month. assuming that the summer season is three months​ (june, july, and​ august) of the year and that the winter season is another three months​ (december, january, and​ february) of the​ year, how much can jenny spend on insulation if she expects to keep the property for five​ years? assume that neither heating nor​ air-conditioning would be required during the fall and spring seasons. if she decides to install the​ insulation, it will be done at the beginning of may.​ jenny's interest rate is​ 6% compounded monthly.
