General Equilibrium

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

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?

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?

Equilibrium Level of Income or GDP

Assume that the consumption 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 expenditu

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

Calculating a competitive industry's long-run equilibrium

A firm in a purely competitive industry is currently producing 1200 units per day at a total cost of $600 . If the firm purchased 1000 units per day, its total cost would be $400, and if it produced 700 units per day, its total cost would be $375. What is the firms ATC per unit at these three levels of production? If every firm

National income and expenditure components

The national income and expenditure components for each level of the economy of Lala Land are given below. What is the total expenditure at each level of income? What is the equilibrium level of GDP? What is the marginal propensity to consume? Using the multiplier, if consumer spending autonomously increases by $200,

Calculate Demand-Side Equilibrium

DEMAND SIDE EQUILIBRIUM ACTIVITY 1. From the following data, find the marginal propensity to consume, compute the expenditure at each level of GDP, and find the equilibrium GDP: GDP C I G X IM 5,000 3,650 1,000 1,200 700 1,100 5,500 4,000 1,000 1,200 700 1,100 6,000 4,350 1,000 1,200 700

Management decisions for a perfectly competitive firm

1. Should a perfectly competitive firm making a loss in the short-run always leave the market? Why or why not? What about in the long-run? 2. Should a perfectly competitive firm advertise in an effort to increase its sales and its profits? Why or why not? 3. Can you think of an example of a perfectly competitive firm? Wh

third-party-payer system on equilibrium price and quantity

Explain the effect of a third-party-payer system on equilibrium price and quantity. I have a neighbor who had bi-pass surgery that cost us all $150,000 and he was 90 years old. This is a 3rd party example where he only has a few years left but was not able to pay to have the surgery done but we taxpayers paid it. Explain if this

Find Cape Despair's new equilibrium levels of real GDP and productivity.

In the economy of Cape Despair, the subsistence real wage rate is $15 an hour. Whenever real GDP per hour rises above $15 the population grows, and whenever the GDP per hour of labor falls below this level, the population falls. The table shows Cape Despair's production function: Labor Real GDP (bil

Game Theory: Inside Oligopoly

In a two play, one shot simultaneous-move game each player can choose strategy A, each earns a payoff of $500. If both players choose strategy A, each ears a payoff of $500. If both players choose strategy B, each earns a payoff of $100. If player 1 chooses strategy A and player 2 chooses strategy b, then player 1 earns $0 and p
