- Suppose that the development of a new drought-resistant hybrid seed corn leads to a 50 percent increase in the average yield per acre without increasing the cost to the farmers who use the new technology. If the producers in the corn production industry were price takers, what would happen to the following? a. the price of corn b. the profitability of corn farmers who quickly adopt the new technology c. the profitability of corn farmers who are slow to adopt the new technology d. the price of soybeans, a substitute product for cornA firm in a perfectly competitive industry has patented a newprocess for making widgets. The new process lowers the firm’saverage cost, meaning that this firm alone (although still aprice taker) can earn real economic profits in the long run. a. If the market price is $20 per widget and the firm’s marginalcost is given by MC=0.4q , where q is the dailywidget production for the firm, how many widgets willthe firm produce? b. Suppose a government study has found that the firm’snew process is polluting the air and estimates the socialmarginal cost of widget production by this firm to be. If the market price is still $20, what is thesocially optimal level of production for the firm? Whatshould be the rate of a government-imposed excise tax tobring about this optimal level of production? c. Graph your results.Can you help with parts d,e and f please? A perfectly competitive firm has the following total cost function: TC = 4,500 + 2q + .0005q2 where TC is total cost in dollars and q is the quantity of output produced. a.

- Consider a perfectly competitive market, where the current number of firms is 50. Each firm has one unit of capital and can product q(1, L) = √L units of output with one unit of capital at a cost v per unit, and L units of labor at a cost w per unit in the short-run. a) Find a firm's short-run supply curve, qs(p), and the industry short-run supply curve, Qs(p). b) Given the market demand, = 10000 - 50p, and the industry short-run supply curve, find the short-run equilibrium price and quantity assuming that w = 1.A firm operates in a perfectly competitive market. The market price of its product is 4 birr and the total cost function is given by TC= 1/3 Q3 - 5Q2+20Q + 50, where TC is the total cost and Q is the level of output.a) What level of output should the firm produce to maximize its profit?b) Determine the level of profit at equilibrium.c) What minimum price is required by the firm to stay in the market?Suppose that many small firms operating in the perfectly competitive market set-up. All firms are identical and have the total cost function c (q)= 40+8q+(q^2/10), where q is the individual firm’s production amount. The market inverse demand function is described as P= A - (Q/50), where A>0 is constant, and Q is the market quantity. In the short-run equilibrium, there are 78 firms in the market, and firm’s maximum profit is $22.5 a) find the short-run equilibrium price b) suppose that in the long-run, firms cost function is still the same C (q)= 40+8q+(q^2/10) (assume LR cost function has fixed component of 40) Find the long-run equilibrium number of firms? (Assume market demand in LR = market demand SR)
- Suppose that the firm operates in a perfectly competitive market. The market price of his product is$10. The firm estimates its cost of production with the following cost function: TC=10q-4q2+q3 A. What level of out put should the firm produce to maximize its profit? B. Determine the level of profit at equilibrium. C. What minimum price is required by the firm to stay in the market?Consider a competitive market in which the market demand for the product is expressed as P = 75 ‑ 1.5Q, and the supply of the product is expressed as P = 25 + 0.50Q. Price, P, is in dollars per unit sold, and Q represents rate of production and sales in hundreds of units per day. The typical firm in this market has a marginal cost of MC = 2.5 + 10q. Determine the equilibrium market price and rate of sales (output). Show your working. Determine the rate of sales (output) of the typical firm, given your answer to part (i) above. If the market demand were to increase to P = 100 ‑ 1.5Q, what would the new price and rate of sales in the market be? What would the new rate of sales (output) for the typical firm be?. Show your working If the original supply and demand represented a long‑run equilibrium condition in the market, would the new equilibrium (iii) represent a new long‑run equilibrium for the typical firm? ExplainThe market for paperback detective novels is perfectly competitive. Market Demand is given by Q=450-6P. Market Supply is given by Q=4P-13. Suppose 21 units are bought to the market. Consider the Marginal Cost of production for these 21 units. What is the maximum Marginal Cost of production of these 21 units? Enter a number only, do not include the $ sign. Hint: 21 doesn't have to be the market quantity.
- A perfectly competitive industry has 150 identical firms. At a price of $8, the typical firm supplies 10 units of output, so the market quantity supplied is nothing units of output. (Enter your response as an integer.)Suppose a firm operating in a perfectly competitive industry has costs in the short run given by: SRTC = 8 + ½q^2 and therefore MC = q. Assuming that the firm is a price-taker operating in a competitive market, derive an expression for the firm’s supply curve, (the profit maximizing output for the firm as a function of the market price, i.e., q^s = f(p). Assuming the firm is one of 100 identical firms in the industry, what is the short-run supply curve for the industry, i.e., Q^s = f(p)? If demand is given by Q^D = 1000 – 100p, what are the short-run equilibrium price, market quantity, and firm quantity? Is this a long-run equilibrium? [Hint: Calculate firm profit in the equilibrium.]. Suppose a firm operating in a perfectly competitive industry has costs in the short run given by: SRTC = 8 + ½q2 and therefore MC = q. Assuming that the firm is a price-taker operating in a competitive market, derive an expression for the firm’s supply curve, (the profit maximizing output for the firm as a function of the market price, i.e., q S = f(p).
