Hence, the profit-maximizing quantity for BYOB ls 2;000 cans of beer per month. BYOB wants to charge the highest price [P] possle at which It can sell all 2,000 cans. BYOB will charge a price on the demand curve that con‘esponds to the point at which the quantity {Q} demanded equals 2,000 cans. Therefore, BYOB will set Its price at $235 per can, the maximum amount that consunErs are willing and able to pay. Economic proflt Is equal to total revenue mlnus total cost: Economic Profit Total Revenue {TR} - Total Cost {TC} {P it Q) - [ATC x Q} [P - ATE) it Q Therefore, you should have shaded In the area between $2.15 and $3.00 and over to 2;000 cans. Because the average total cost ($3.00 per can} Is greater than the price [$2.75 per can) at the profit-maximizing tiuaritihu'r BYOB is suffering a loss. Suppose that BYOB chargEs $2.35 per can. Your friend Dmltrl says that sInce BYOB Is a pure monopoh,I wltn market power, it should charge a hlgher prIce of $3.00 per can. Dmltri clalms that BYOB would break even If it dld thls.

Explanation: Close A IIr BYOB charges $3.00 per can of been then quantltv demanded Is only 1.600 cans per month, as gIUEn by the market demand curve. At this qLJantlty, total revenue Is prlce timEs qUantity, or $4,300 per month, and total cost is quantity times average total cost ($3.50 per can), or $5,500 per month. This rasults In a loss of $800 per month, compared with a loss of $500 per month when prodUclng 2,000 cans per month and charging $2.35. Therefore, the losses suffered are greater if BYOB chooses to sell a can of beer at $3.00 rather than $2.35. Dmltri ls incorrect. 5.0 MonopolvDutcome 5"] MC .4».

Hence, the profit-maxlmlzing quantity for BYOB Is 2,000 cans of beer per month. BYOB wants to charge the highest price (P) possible at whlch it can sell all 2,000 cans. BYOB will charge a price on the demand curve that oorresponds to the polnt at whlch the quantltv {Q} demanded equals 2,000 cans. Hence, BYOB Iwill set its price at $235 per can, the mavlmum amount that consumers are wiIIIng and able to pay. Economlc profit is total revenue mInLIs total cost: Economic Proflt Total Revenue (TR) — Total Cost {TC} = {P}: Q} — {ATEXQ} [P—ATC) HQ Therefore, you should have shaded in the area bath-dean $2.25 and $235 and war to 2,000 cans. BacaLJse the average total cost ($2.25 per can) is less than the price {$2.35 per can} at the profIt-mammIzing quantity, BYOB Is makan a proflt.

Consumer surplus is the dlfferenoe between the price consumers are willing to pay and what they actually pay for a good‘ Graphicallyr consumer surplus Is the area bounded from above by the demand curve and from below by the edulllbrlurn pnoe.

Explanation: Close A The hot dog stand will produce the level of output at whlch lts marglnal revenue ls equal to Its marginal cost; this ooours at 40 hot dogs per day. It will charge a monopolist‘s prlce of $3.00, the maylmum amount oonsumers are wllling to pay at this output level (as determlned by the demand curve]. Consumer surplus is the difference between the price consumers are wllling to pay and what they actually pay for a good.
