2. Superior Metals Company has seen its sales volume decline over the last few years as the result of rising foreign imports. In order to increase sales (and hopefully, profits), the firm is considering a price reduction on luranium–a metal that it produces and sells.

PROBLEMS

1. Two companies (A and B) are duopolists that produce identical products. Demand for the products is given by the following demand function:

P = 10,000−QA−QB

where QA and QB are the quantities sold by the respective firms and P is the selling price.

Total cost functions for the two companies are:

TCA = 500,000 + 200QA + .5QA2
TCB = 200,000 + 400QB + QB2

Assume that the two firms act independently as in the Cournot model (that is, each firm assumes that the other firm’s output will not change). Determine the long-run equilibrium output and selling price for each firm.

14. The Coase Theorem works best in places that transaction costs for contracts among people is low. Often in the world of torts and externalities both parties can claim that they have rights to impose on others. One case is that of a railroad that is noisy and scares the cattle and the rancher whose cattle sometimes wander in front of moving trains causing damage to them and the train. What does the Coase say would happen?
a. The train should have property right to be safe from wandering cattle, and the rancher should be liable for train damage of rampaging cattle.
b. The rancher should have the property right to be safe from noisy trains, and the railroad should be liable for weight loss of cattle from train whistles and rumbling noise.
c. If transaction costs are low, the efficient activity will occur, either the rancher or railroad installing fences to protect from rampaging cattle and/or sound insulation with trees, or if it is cheaper, fewer train trips per day. The cheapest or most efficient solution will happen, regardless of who is assigned the original property right.

2. The capital structure of Wildcat Wells, an independent petroleum exploration and drilling company, consists of 40 percent debt and 60 percent equity capital. Debt capital consists of a bond (which matures in 10 years) issued five years ago at an interest rate of 10 percent. Since then market interest rates have risen substantially. The firm has been advised by its investment banker that additional debt financing (bonds) could be obtained at a rate of 12 percent.

In addition, indirect benefits of \$12,500 per year for 25 years have been projected. Increased values in land surrounding the project will provide immediate, one-time pecuniary benefits to the land-owners of \$1,000,000.

The direct cost to operate and maintain the park is estimated at \$50,000 per year. The Ministry believes a 10% discount rate is appropriate to evaluate projects of this sort. Should the park be built? Justify your answer using cost benefit analysis.

” Moral Hazard”
The managerial economist runs into moral hazard issues frequently. It is also in our political system. Just listen to Donald Trump as he describes contributing to all sorts of campaigns of people with both parties so he could get favors later on. He knows how the system works, and says correctly it is filled with moral hazard, and he wishes to put a damper on it. He says our system is broken. WATCH THIS VIDEO . https://www.youtube.com/watch?v=BtvPewHoXtM

Robert Reich interesting observations–Corporate tax “reform” is high on the Republican agenda because the GOP’s corporate patrons are demanding payoff from their investments in the 2014 election. Watch your wallets. Here are the four biggest right-wing whoppers about corporate taxes:
1. The U.S. corporate tax rate of 35% is one of the highest among advanced countries. True but misleading. The effective corporate income-tax rate – what corporations actually pay after all deductions, credits, and loopholes – is 27.7%, close to the average of all rich countries (27.2%).
2. Today’s corporate tax rate is high by historic standards. Baloney. In the 1950s it was over 50%.
3. The corporate tax reduces corporate profits, which makes it harder for corporations to hire. Wrong. Corporate profits today are the highest they’ve been since World War II as a percentage of the economy.
4. Lowering the corporate income-tax would spur economic growth. Baloney. There’s no relation between corporate tax rates and growth. In the 1950s and 60s, when the corporate tax was over 50%, the economy grew faster (at an annual average rate of 3.9%) than it has since the rate was reduced.
