General Equilibrium

Compare the economic incidence of tax with its legal incidence

Suppose that demand for oranges is given by the following equations: Q= -400 P+2,000 With quanity (Q) measured in oranges per day and price (P) measured in dollars per Orange. The supply curve is given by: Q = 1200 P A. Compute and present graphically the equilibrium price and quantity of oranges. B.

Price Leadership

Over the last century, the Boeing Co. has grown from building planes in an old, red boathouse to become the largest aerospace company in the world. Boeing's principal global competitors is Airbus, a French company jointly owned by Eads (80 percent) and BAE systems (20percent). Airbus was established in 1970 as a European conso

Assume that initially G is $100 and equilibrium real GDP demanded is $1,000. If the multiplier is 4 and G increases to $200, real GDP demanded will increase a. by $100 b. by $2,000 c. by $1,000 d. to $1,400 e. to $2,000 If autonomous net taxes decline by $40 billion and the MPC = 0.75, then equilibrium real GDP demanded

Stable Competitive Equilibrium

Bada Bing,Ltd. supplies standard 256 MB RAM chips to the US computer and electronics industry. Like the output of its competitors, Bada Bings Chips must meet strict size,shape,and speed, specifications. As a result the chip supply industry can be regarded as perfectly competitive.

1. A study has estimated the effect of changes in interest rates and consumer confidence on the demand for money to be: log M = 14.666 + .021 log C - .036 log r, where M denotes real money balance. C is an index of consumer confidence, and r is the interest rate paid on bank deposits. Based on this study, a 5% increase in inte

Consider a small city's dry-cleaning market, which is monopolistically competitive. Currently, the typical dry-cleaner is charging $5 an item. The average cost of dry-cleaning is $2. The typical dry-cleaners clean 1,000 items per week. (Each customer drops off approximately 4 items). Suppose, a new dry-cleaner was to enter t

Output Levels

Assume that GDP (Y) is 5,000. Consumption is C=1,000+.3(Y-T). Investment is I=1500-50r, where r is the real interest rate. Taxes (T) are 1,000 and government expenditures (G) are 1,500. a). Calculate the equilibrium values of C, I, and r. b). Calculate the equilibrium values of private saving, government saving, and tota

Price Ceilings

The local government in a west Coast college town is concerned about a recent explosion in apartment rental rates for students and other low-income renters. To combat the problem, a proposal has been made to institute rent control that would place a $900 per month ceiling on apartment rental rates. Apartment supply and demand co

Managerial Economics

16) If demand increases while supply decreases for a particular good: a. its equilibrium price will increase while the quantity of the good produced and sold could increase, decrease, or remain constant. b. the quantity of the good produced and sold will decrease while its equilibrium price could increase, decrease, or remain

Behaviour of firms in oligopoly markets

Critically discuss that there is no satisfying theory that explains the behaviour of firms in oligopoly markets. Which theories should I include in the analysis? Which examples are relevant to these theories? Furthermore, may you include some journals that will enhance my understanding of the key points that you will include

Suppose the market demand curve in an industry is characterized by P=1-Q, where P is the market price and Q is the total quantity supplied to the market. Suppose there are three firms in this industry. All have a zero marginal cost of production.

What are the pure strategy Nash Equilibria of this game?

Suppose that a cake is being divided in the following way among two players. Each player writes down a number from zero to one on his piece of paper. Then both players turn over their pieces of paper. If the sum is less than or equal to one, each player gets a share of the cake equal to the number he wrote. If the sum is bigge

Consumer surplus /deadweight

If QD=100-6P and QS=4p I understand how to get the equilibrium of p=10 and Q=40 but I need to find consumer and producer surplus does that get calculated? b) How does the equilibrium change if a price floor of $12 is put in place? Calculate deadweight loss from this price floor. c) Suppose a tax of t=$2 is
