1. Calculate Revenues, COGS, Gross Profit and Gross Margin in year 2 based on the

following:

Yr. 1

Revenues 500

COGS 400

Gross Profit 100

Gross Margin 20%

Sales rise 5%, 3% due to increase in volume and 2% due to increase in price. COGS is 80% variable.

2. What is the primary driver of sales growth for the following company? Explain.

Assume COGS is 60% variable.

Yr. 1 Yr. 2

Revenues 800    850

COGS 500 519

Gross Profit 300 331

Gross Margin 37.5% 38.9%

On January 1, you sold short 100 shares of XYZ stock at $20 using a 50% initial margin. The interest rate on the margin account is 10% annually. On April 1 (in three-months), you covered the short sales by buying stock at a price of $15 per share. You paid 50 cents per share in commissions for each transaction. Assume you received interest on all your assets, i.e. the sum of the short sale proceeds and the margin.
1. What is the value of your assets and equity on April 1?
2. What is the total rate of return on equity?

1. Show the effect of people becoming more patient in the BOND MARKET. (Note: this is not the same as the loanable funds market.....Well, it kind of IS the same market, but it's not the same graph! Come on man, just think about it....)

2. Consider the equation of exchange. (Use the version with the values NOT the rates of change.) Let's assume that velocity is constant at 3, the money supply is 4,000. Give the price level that goes with each of the following levels of real output. Then plot them on a graph and draw a line through them. This curve will be back in a later episode.

A monopolist faces the following demand curve, marginal revenue curve, total cost curve and marginal cost curve for its product: Q = 200 ; MR = 100-Q ; TC = 5Q ; MC = 5

a) Suppose that a tax of $5 for each unit produced is imposed by state government. What is the profit maximizing level of output?

b) Suppose that a tax of $5 for each unit produced is imposed by state government. What is the profit maximizing price?

c) Suppose that a tax of $5 for each unit produced is imposed by state government. How much profit does the monopolist earn?

Michael lives on an island and owns a beach house worth $400,000. Of that, $100,000 is the cost of land and $300,000 is the cost of the structure. The probability that a hurricane destroys his house is 3 percent (he will still own the land). Michael can purchase hurricane insurance at the price of $2 for each $100 of coverage.

1. What is Michael’s contingent consumption bundle if Michael does not purchase insurance?

2. What is Michael’s contingent consumption bundle if Michael purchases $300,000 of insurance coverage?

3. Derive the equation of Michael’s budget constraint.

4. Plot Michael’s budget constraint on the graph.

Stewart Co. is the producer of tires. They sell a constant mix of 3 Medium sized tires for every 2 small tires, and 4 medium tires for every 3 large tires.

Total fixed costs for the year are 2,037,550

(round all intermediate calculations to three decimal places)

Selling price per tire Small:100 Medium:150 Large:250

Variable Cost per tire S:60 M:96 L:160

What is the weighted average contribution margin ratio for each sized tire?

What is the breakeven point for each sized tire?
