General Equilibrium

Effect of a natural disaster on market supply and demand.

Suppose you are asked to do a market analysis in an area in which a natural disaster has recently occurred. For example, Nashville after the Spring floods or New Orleans after Hurricane Katrina. Other than building supplies, choose a market for a good or service that will be affected. Will demand or supply be affected? What h

What is the impact of a $20 billion tax cut on consumption and GDP?

Assuming an economy can be represented by the following simplified model (all values are measured in $billion): C=200+0.5Yd, I=100, G=150, TP=100, X=M, Yd=Y-TP Please discuss the impacts of a $20 billion tax (TP decrease by 20) cut on equilibrium Y (GDP) and C (personal consumption).

Equations of the IS and LM Curves

Consider the following numerical version of the IS-LM model in a closed economy: C=400+0.5Yd; I=700-4000r+0.1Y; G=200; TP=200; Yd=Y-TP RLMD=0.5Y-7500r; RLMS =500; X=M A) Find the equations for the IS curve and LM curve. B) Solve for equilibrium real output (Y), interest rate (r), consumption (C), and Invest

Questions about marginal external costs are posed.

Questions 1. The marginal external cost associated with air pollution increases with the annual output of a polluting industry. At the current competitive equilibrium level of output per year the marginal external cost is $10 per unit of output. To achieve efficiency, a) a corrective tax of $10 per unit of output is req

Production Possibilities Frontier

Can you please help on sketching a PPF for two goods that you choose. Assume the economy is in equilibrium at one point on the curve (label that point A)? Explain which events would cause the economy to move from point A to either a point inside the curve, another point on the curve, or a point outside the curve.

Long run equilibrium of a perfectly competitive industry

1- characterize the long run equilibrium of a perfectly competitive industry in which average costs are U-shaped as output increases, under both restricted and free entry. 2-Discuss the senses in which a perfectly-discriminating monopolist is efficient or inefficient.


1) Are monopolists guaranteed of making economic profits? 2) Explain the long run equilibrium situation for a monopolistically competitive industry. Give two examples of industries that fit under this category.

A perfectly competitive firm

Question: 1. The graph the follows (see attached file) shows an individual firm in long-run equilibrium. In which market structure is this firm operating? Explain.
