General Equilibrium

Oligopoly theories

Is there a satisfactory theory that describes behaviour of oligopolies discuss?

total profit of the firm

Suppose all of the firms in a small sconomy satisfy the conditions for efficiency except for one firm, LuthorCorp, which is a monopolu producer of computer anti-virus programs. LuthorCorp is also the only hirer of anti-virus program engineers in this economy. Suppose the production function for anti-virus program is Q=F(L)=2L, w

Dominant Strategy Notes

Suppose Firms A and B sells competing products and is deciding whether to undertake advertising campaigns. Each firm will be affected by its competitor decision. The possible outcomes of the game are illustrated by the payoff matrix below.

General equilibrium theory

Let's derive a few more results based on our ongoing white-collar / blue-collar, energy / food example (as covered in class last Wednesday and summarized further in the "Addendum" nibble in Coursework). In answering the following questions, you may refer to your class notes and the Addendum. You don't need to do any calculus

Pork farming, consumption function

There is a vast number of hog farmers in Canada. The Industry should be a good approximation to a perfectly competitive market. The demand for processed pork in Canada is: The D should be subscript QD = 286-20p, where QD = quantity of pork demanded in millions of kg per year p = the price of pork in Canadian dollars per kg

Economics help

Assume that a firm sells its product in a perfectly competitive market. The firm's fixed costs (including a "normal" return on the funds the entrepreneur has invested in the firm) are equal to $100 and its variable cost schedule is as follows: Output (Units) Variable Cost per Unit 50 $5.00 100 4.50 150 4.00 200

Marginal Cost and an Average Cost Schedule

Assume that a firm in a perfectly competitive industry has the following total cost schedule: Output (units) Total Cost ($) 10 $110 15 150 20 180 25 225 30 300 35 385 40 480 a. Calculate a marginal cost and an average cost schedule for the firm. b. If the prevailing market price is $17 pe

firms in a monopolistically competitive market

A "One might expect firms in a monopolistically competitive market to experience greater swings in the price of their products over the business cycle than those in an oligopoly market. However, fluctuations in profits do not necessarily follow the same pattern." Discuss this statement. B Market Structure Concepts: Ind

Practice problems in game theory

I'm doing practice problems for an exam in a game theory course and I want solutions by some one more knowledgeable, so that I could see if I did them right.

Steady-state capital per worker

In this problem, assume that Mexico and the United States have the same aggregate production function, the same δ (value for depreciation of capital stock), and the same n . In Mexico, real GDP per worker in 2000 is about 40% what it is in the United States, but Mexico is not near its steady-state level of output. 1. If

Analysis of IS/LM curves

1 Carefully explain and show graphically how each of the following changes would effect the shape of the IS curve: a) The MPC becomes bigger. b) Investment becomes more sensitive to changes in the real interest rate. 2 In the State of the union address in January 2002, President Bush announced that he would ask Congress to

Calculating dead weight loss (lost efficiency.)

Here's what I think I know about the answer: to get the $ value of DWL you have to take the area of the aggregate surplus under perfect competition and substract the area of the aggregate surplus under monopoly (helps to make a little graph.) The funny thing is, my main problem is I don't know the geometry necessary to do that.
