In the US cotton market, each farm having the cost function c(q)=0.5q^(2)+ 10 q+162 where q is the quantity of cotton in tons produced by each farm. The market demand curve is given by Q^(d)=10,400-50 p. Suppose the government gives each farm a subsidy of $8 per ton. Calculate the long-run market price assume the market is perfect competition. $20 $25 $30 $35 With all steps clearly

4. A vertically integrated automobile company has an upstream engine division and a downstream assembly division. The demand for the company's cars is given by Q = 20-P. Each car requires one engine. The downstream division's total cost of assembling cars is TCD(Q) = 4Q. The upstream division's total cost of producing engines is TCv (Q) = Q². (a) Suppose that there is no outside market for engines. What is the price and quantity of cars produced by the company? (b) Suppose that there is no outside market for engines. What should be the transfer price for engines? [Hint: the transfer price of an engine should equal the marginal cost of engine production at the optimal quantity.] (c) Suppose that there is a competitive outside market in which the price of an engine is 12. What is the price and quantity of cars produced by the company? (d) Suppose that there is a competitive outside market in which the price of an engine is 12. What is the quantity of engines that the company buys or…

Could you solve the 4. question as follows shut down and operate TR= TFC= TVC= TC = PROFİT= The demand curve and supply curve for a perfectly competitive market are: Q = 500 – 5P and Q = 320 + P. The short run cost function of a representative firm in this market is TC = 150 + 3q2. According to these information Calculate the equilibrium price and quantity for this market. Calculate the profit maximizing output of this representative firm. Calculate the profit of this firm. Analyze this firm’s position in terms of shut down condition. Should this firm operate or shut-down in the short run. If all firms had the same cost structure, how many firms would compete at the equilibrium price computed in (a) above?
Suppose Robin's Clock Works produces in a perfectly competitive market. Suppose the average total cost of clocks is $95, the average variable cost of clocks is $90, and the price of clocks is $85. If the firm is producing the level of output where marginal cost equals price, then in the short run the firm: A) can increase profit by increasing output.B) is earning a positive economic profit.C) should continue to produce since total revenue exceeds total variable cost.D) should shut down.
The following graph plots daily cost curves for a firm operating in the competitive market for fitness trackers. Hint: Once you have positioned the rectangle on the graph, select a point to observe its coordinates. PRICE(Dollars pertracker) 100 90 70 60 50 40 20 10 0 0 MO ATC AVC 50 60 70 80 10 20 30 40 QUANTITY (Thousands of trackers per day) 90 100 Profit or Loss In the short run, given a market price equal to $45 per tracker, the firm should produce a daily quantity of trackers. On the preceding graph, use the blue rectangle (circle symbols) to fill in the area that represents profit or loss of the firm given the market price of $45 and the quantity of production from your previous answer. Note: In the following question, enter a positive number regardless of whether the firm earns a profit or incurs a loss. The rectangular area represents a short-run thousand per day for the firm.

7. Short-run supply and long-run equilibrium Consider the perfectly competitive market for steel. Assume that, regardless of how many firms are in the industry, every firm in the industry is identical and faces the marginal cost (MC), average total cost (ATC), and average variable cost (AVC) curves shown on the following graph.

Use the orange points (square symbol) to plot the short-run industry supply curve when there are 20 firms in the market. (Hint: You can disregard the portion of the supply curve that corresponds to prices where there is no output since this is the industry supply curve.) Next, use the purple points (diamond symbol) to plot the short-run industry supply curve when there are 30 firms. Finally, use the green points (triangle symbol) to plot the short-run industry…
