Economics 18th edition Campbell R. McConnell, Stanley L. Brue, Sean M. Flynn - Solutions
Explain how featherbedding and other restrictive work practices can reduce labor productivity. Why might strikes reduce the economy’s output less than the loss of production by the struck firms?
What is the estimated size of the union wage advantage? How might this advantage diminish the efficiency with which labor resources are allocated in the economy? Normally, labor resources of equal potential productivity flow from low-wage employment to high-wage employment. Why does that not happen
Contrast the voice mechanism and the exit mechanism for communicating dissatisfaction. In what two ways do labor unions reduce labor turnover? How might such reductions increase productivity?
How does the economist’s use of the term “rent” differ from everyday usage? Explain: “Though rent need not be paid by society to make land available, rental payments are very useful in guiding land into the most productive uses.”
Explain why economic rent is a surplus payment when viewed by the economy as a whole but a cost of production from the standpoint of individual firms and industries. Explain: “Land rent performs no ‘incentive function’ for the overall economy.”
In the 1980s land prices in Japan surged upward in a “speculative bubble.” Land prices then fell for 11 straight years between 1990 and 2001. What can we safely assume happened to land rent in Japan over those 11 years? Use graphical analysis to illustrate your answer
How does Henry George’s proposal for a single tax on land relate to the elasticity of the supply of land? Why are there so few remaining advocates of George’s proposal?
If money is not an economic resource, why is interest paid and received for its use? What considerations account for the fact that interest rates differ greatly on various types of loans? Use those considerations to explain the relative sizes of the interest rates on the following: a. A 10-year
Why is the supply of loanable funds upsloping? Why is the demand for loanable funds downsloping? Explain the equilibrium interest rate. List some factors that might cause it to change.
Suppose that the interest rate is 4 percent. What is the future value of $100 four years from now? How much of the future value is total interest? By how much would total interest be greater at a 6 percent interest rate than at a 4 percent interest rate?
Here is the deal: You can pay your college tuition at the beginning of the academic year or the same amount at the end of the academic year. You either already have the money in an interest-bearing account or will have to borrow it. Deal or no deal? Explain your financial reasoning. Relate your
What are the major economic functions of the interest rate? How might the fact that many businesses finance their investment activities internally affect the efficiency with which the interest rate performs its functions?
Distinguish between nominal and real interest rates. Which is more relevant in making investment and R&D decisions? If the nominal interest rate is 12 percent and the inflation rate is 8 percent, what is the real rate of interest?
Historically, usury laws that put below-equilibrium ceilings on interest rates have been used by some states to make credit available to poor people who could not otherwise afford to borrow. Critics contend that poor people are those most likely to be hurt by such laws. Which view is correct?
How do the concepts of accounting profit and economic profit differ? Why is economic profit smaller than accounting profit? What are the three basic sources of economic profit? Classify each of the following according to those sources: a. A firm’s profit from developing and patenting a new
Why is the distinction between insurable and uninsurable risks significant for the theory of profit? Carefully evaluate: “All economic profit can be traced to either uncertainty or the desire to avoid it.” What are the major functions of economic profit?
Explain the absence of economic profit in a purely competitive, static economy. Realizing that the major function of profit is to allocate resources according to consumer preferences, describe the allocation of resources in such an economy.
What is the combined rent, interest, and profit share of the income earned by Americans in a typical year if proprietors’ income is included within the labor (wage) share?
Assume that you borrow $5000 and pay back the $5000 plus $250 in interest at the end of the year. Assuming no inflation, what is the real interest rate? What would the interest rate be if the $250 of interest had been discounted at the time the loan was made? What would the interest rate be if you
Describe Thomas Malthus’ theory of human reproduction. Does it make sense for some species—say bacteria or rabbits? What do you think makes humans different?
Suppose that the current (first) generation consists of 1 million people, half of whom are women. If the total fertility rate is 1.3 and the only way people die is of old age, how big will the fourth generation (the great-grandchildren) be? How much smaller (in percentage terms) is each generation
Demographers have been very surprised that total fertility rates have fallen below 2.0, especially because most people in most countries tell pollsters that they would like to have at least two children. Can you think of any possible economic factors that may be causing women in so many countries
Resource consumption per person in the United States is either flat or falling, depending on the resource. Yet living standards are rising due to improvements in technology that allow more output to be produced for every unit of input used in production. What does this say about the likelihood of
Suppose that you hear two people arguing about energy. One says that we are running out of energy. The other counters that we are running out of cheap energy, explain which person is correct and why.
A community has a nighttime energy demand of 50 megawatts but a peak daytime demand of 75 megawatts. It has the chance to build a 90-megawatt coal-fired plant that could easily supply all of its energy uses even at peak daytime demand. Should it necessarily proceed? Could there be lower-cost
Recall the model of nonrenewable resource extraction presented in Figure.Choosing the optimal extraction levelSuppose that a technological breakthrough means that extraction costs will fall in the future (but not in the present). What will this do to future profits and, therefore, to current user

Suppose that a government wants to reduce its economy’s dependence on coal and decides as a result to tax coal mining companies $1 per ton for every ton of coal that they mine. Assuming that coal mining companies treat this tax as an increase in extraction costs this year, what effect will the
User cost is equal to the present value of future profits in the model presented in Figure.Choosing the optimal extraction levelWill the optimal quantity to mine in the present year increase or decrease if the market rate of interest rises? Does your result make any intuitive sense?
Various cultures have come up with their own methods to limit catch size and prevent fishery collapse. In old Hawaii, certain fishing grounds near shore could be used only by certain individuals. And among lobstermen in Maine, strict territorial rights are handed out so that only certain people can
Aquaculture is the growing of fish, shrimp, and other seafood in enclosed cages or ponds. The cages and ponds not only keep the seafood from swimming away but also provide aquaculturalists with strong property rights over their animals. Does this provide a good incentive for low-cost production as
The figure in the Last Word section shows that a 10-fold increase in a country’s GDP per person is associated with about a 20-point increase in EPI. Do you think that this pattern can be extrapolated out into the future? That is, could the United States (which currently has an EPI of 78.5) gain

Explain and evaluate: “Industry complains of the higher taxes it must pay to finance subsidies to agriculture. Yet the trend of agricultural prices has been downward while industrial prices have been moving upward, suggesting that on balance agriculture is actually subsidizing industry.”
