Game Theory and Asymmetric Information

1. a. You and a competing firm are the only sellers of a new product. You are engaged in an intense battle for initial market share. You both realize that the one who captures most of the market share will be the one who spends the most on advertising and promotion. You are the marketing manager and you have up to $1 million fo

Equilibrium Parameters: Price and Quantity

a. Initially, the peanut market is perfectly competitive, and each firm has minimum average cost equal to 5 (remember, MC = AC at minimum AC). Find the competitive price and quantity. b. One firm buys all of the other peanut firms, obtaining a monopoly in the peanut industry. The monopoly has constant returns to scale and

Demand and Supply in Competitive Markets

The market for hog hats is competitive and demand is given by P=75-Q while supply is given by P=15+2Q. What are the equilibrium price and quantity in this market? Calculate the elasticity of demand at a price of 50. Give an economic interpretation to your answer. Is demand elastic, unit elastic or inelastic at this price?

Multiplier size

Assume that the consumption schedule for a private open economy is such that consumption C= 50+0.8Y. Assume further that planned investment I g =30 and X n=10. Recall also that in equilibrium, the real output produced (Y) is equal to aggregate expenditures: Y =C+I g + X n A) Calculate the equilibrium level of income or real

Solving for Optimal Combination of Inputs

The Largo Publishing House uses 400 printers and 200 printing presses to produce books. A printer's wage rate is $20, and the price of a printing press is $5,000. The last printer added 20 books to total output, while the last press added 1,000 books to total output. Is the publishing house making the optimal input choice? Why o

Describe a situation where prices have been held out of equilibrium due to government intervention in the market-the obvious ones discussed in the text are rent control and agricultural subsidies. You may use a specific example of one of these, or any other example. b. Were there any unintended consequences in your example?

Microeconomics Advanced Analysis

Assume that the consumption of schedule for a private open economy is such that consumption C = 50 + 0.8Y. Assume further that planned investment Ig and net exports Xn are independent of the level of real GDP and constant at Ig = 30 and Xn = 10. Recall also that, in equilibrium, the real output produced (Y) is equal to aggregate

Equilibrium Level of Income or GDP

Assume that the consumption schedule for a private open economy is such that consumption C=50+0.8Y.

ATC

A firm in a purely competitive industry is currently producing 1000 units per day at a total cost of $450. If the firm produced 800 units per day , its total cost would be $300, and if it produced 500 units per day,its total cost would be $275. What are the firms average total cost per unit a these levels of productions? If ever

Oligopoly and payoff table

Two oligopoly firms are in the process of evaluating their marketing strategies. Firm 1 can generate estimated profits of $10 million from strategy A if the second firm reacts by strategy C, and $15 million from strategy A if the second firm reacts with strategy D. On the other hand, Firm 1 may follow strategy B which could retu

A firm in purely competitive industry is currently producing 1200 units per day at a total cost of $600. If the firm produced 1000 units per day, its total cost would be $400, and if it produced 700 unit per day, its total cost would be $375.
