Suppose a perfectly competitive industry is in long-run equilibrium. If a decrease in demand leads to a lower long-run price, we know that
A) this is a decreasing-cost industry. B) this is an increasing-cost industry. C) some firms will be losing money in the long run. D) after further adjustments, price will rise to its original level.
Desired consumption is Cd = 2000 + 0.9Y - 100,000r - G, and desired investment is Id = 1000 - 45,000r. Real money demand is Md/P = Y - 6000i. Other variables are ?e = 0.03, G = 500, 
= 1000, and M = 2100.(a)Find the equilibrium values of the real interest rate, consumption, investment, and the price level.(b)Suppose government purchases decline to 400. What happens to the variables listed in part (a)? (c)Suppose government purchases rise to 600. What happens to the variables listed in part (a)? (d)What feature in this example leads to the result that you don't need to know the amount of taxes collected by the government to find the equilibrium?
