- Three firms are producing a good and are competing in prices: consumers buy from the firm that has the lowest price, and each firm on its own can satisfy the entire market. If more than one firm choose the same price the demand is divided equally among them. There are no other firms in the market. Two firms have the same constant marginal cost cL and the third one has a higher marginal cost cH : cL < cH . Explain what will be the equilibrium price in this market.Coke and Pepsi dominate the cola market. Suppose that the marginal cost of making cola is $2. Assume also that the demand for cola is given by the following table: Price $8 7 6 5 4 3 2 1 Quantity 5 cans 6 7 8 9 10 11 12 If there were a large number of producers, so that the cola market was competitive, how many bottles of cola would be sold? Type your answer...Two firms facing a demand curve are P = 50 -5Qwhere Q = Q1 + Q2. The cost functions of the two firms are:C1(Q1) = 20 + 10Q1C2(C2) = 10 + 12Q2Based on this information:a.

- The figure below shows the supply and the demand for a good (left) and the cost curves of an individual firm in this market (right). Assume that all firms in this market, including the potential entrants, have identical cost curves. Initially, the market is in equilibrium at point A. Price Cost MC ATC A 4 2 1 D 2 4 6 8 10 12 Quantity Quantity Refer to the figure above. Suppose that the market has reached the long-run equilibrium. Then, due to news of the product's defects and recall, the demand falls by 4 units at each price. At the new equilibrium, each firm in the market earns and there will be a. zero economic profit; neither entry nor exit of firms b. positive economic profit; entries of new firms C. zero accounting profit; both entry and exit of firms d. negative economic profit; exit of existing firmsSuppose that each firm in a competitive industry has thefollowing costs: Total cost: TC=50 + 1/2q^2 Marginal cost: MC=q where q is an individual firm’s quantity produced. The marketdemand curve for this product is Demand: QD = 120 – P where P is the price and Q is the total quantity of the good.Currently, there are 9 firms in the market. a.

At what quantity is average total cost curve atits minimum? What us marginal cost and average total cost at thisquantity? c. Give the equation each firm’s supply curve. d. Give the equation for the market supply curve for the shortrun in which the number of firms is fixed. e. What is the equilibrium price and quantity for this market inthe short run? f.

Is there incentive for…Short-run supply and long-run equilibrium Consiber the competitive market for rhodium. Assume that no matter how many firms operate in the induatry, every firm is identical and faces the same marpinal cost (MC), averapt total cost (ATC), and average variable cost (AVC ) curves plotted in the following praph. The following graph plots the market demand curve for thodium. If there were 10 firms in this market, the short-run equilibrium price of rhodium would be per pound. At that price, firms in this industry would. Therefore, in the long run, firms would the rhodium market. Because you know that competitive firms earn economic profit in the long run, you know the long-run equilibrium price must be per pound. From the graph, you can see that this means there will be firms operating in the rhodium industry in long-run equilibrium. True or False: Assuming implicit costs are positive, each of the firms operating in this industry in the long run earns positive accounting profit. True False
- The graph above illustrates the electricity market. Consider market competition between firms where price is based on AR and select the most appropriate answer. Question 5 options: in the short-run, the demand curve and average revenue shift as other firms enter the market and increase competition. in the short-run, the demand curve and average revenue shift as other frims leave the market and decrease competition. in the long-run, the demand curve and average revenue shift as other frims enter the market and increase competition. in the long-run, the demand curve and average revenue shift as other frims leave the market and decrease competition.Carl and Simon are the only sellers of pumpkins at the market, where the total demand function for pumpkins is q =3 ,200−1,600p. The total number of pumpkins sold at the market is q = qC + qS, where qC is the number that Carl sells, qS is the number that Simon sells. The cost of producing pumpkins for each farmer is $.50 per pumpkin; the fixed costs are zero. .a. Find the Cournot equilibrium price and quantities. .b. Find the Bertrand equilibrium price and quantities. . .c. Suppose now that every spring the snow thaws off of Carl’s pumpkin field a week before it thaws off of Simon’s. Therefore, Carl can plant his pumpkins one week earlier than Simon while predicting Simon’s choice based on the previous year information. Simon observes Carl’s choice and chooses how much pumpkin to plant. Find the new equilibrium price and quantities. .d. Compare the quantities and prices in parts a, b, and c. Rank these outcomes according to Pareto efficiency.WEBCAM RECORDING Industrial Economics da 6 A market is characterised by an inverse demand curve p =8 – 2Q where Q is total quantity.
