Unformatted text preview: increases to Q D = 1200 – 50P. e. In the short run (the number of firms does not change), what is the new market quantity (Q) and price (P)? (Hint: Use Q s from part d) Set Q S =Q D 25P=1200 – 50P 75P=1200 P*=1200/75=16 f. Under the new equilibrium price, how many reams of paper (q) will each firm produce? Also find the profit per firm. q S =P/2 =16/2=8 Profit=(P-ATC)*q=(16-11.125)*8=12.875*8=103 Note: ATC=(25/8)+8=3.125+8=11.125 g. In the long run, what will be the market quantity (Q) and price (P)? In the Long run, P=MC=ATC=10 Q D =1200-50*16=1200-800=400 h. In the long run, how many firms are in this industry? N=Q/q=400/5=80 30 new firms entered this market due to the positive profit opportunity....
