Which of the following is an example of an efficiency-equity trade-off faced by economic agents? A) According to an article by in the American Journal of Public Health by Edward Kaplan and Michael Merson of Yale University School of Medicine, the federal government's current method of allocating HIV-prevention resources is not cost-effective. Instead of allocating resources to states in proportion to reported AIDS cases, resources should flow first to those activities that prevent more infections per dollar and then to less and less effective combinations of programs and populations until funds are exhausted, even if it means that some populations would be left without any prevention services. B) Concerned about the falling birth rate, the French government has pledged more money for families with three children, in an effort to encourage working women to have more babies.

What is an economic variable?
Answer: An economic variable is something measurable that can have different values, such as the wages of software programmers.
77) What is meant by the statement that "optimal decisions are made at the margin"?
Answer: In economics, the word "marginal" means "extra" or "additional." Economists reason that the optimal decision is to continue any activity up to the point where the marginal benefit equals the marginal cost, so optimal decisions are made at the point where the extra benefit received from an activity is equal to the extra cost associated with that activity.

Define microeconomics.
Microeconomics is the study of how households and firms make choices, how they interact in markets, and how the government attempts to influence their choices.
DeShawn's Detailing is a service that details cars at the customers' homes or places of work. DeShawn's cost for a basic detailing package is $40, and he charges $75 for this service. For a total price of $90, DeShawn will also detail the car's engine, a service that adds an additional $20 to the total cost of the package. Should DeShawn continue to offer the engine detailing service?
No, his marginal benefit is less than his marginal cost.
What is opportunity cost?
Opportunity cost refers to the highest-valued alternative that must be given up to engage in an activity. For example, the opportunity cost of taking this economics class is what you are giving up to take the class, which may be taking another class such as accounting or psychology, working extra hours at your job, or extra sleep (whichever is your highest-valued alternative).
What is the difference between positive economic analysis and normative economic analysis? Give one example each of a positive and normative economic issue or question or statement.
Positive economic analysis is concerned with what is. Positive economic analysis reaches conclusions based on verifiable statements. Normative economic analysis, on the other hand, is concerned with what ought to be. Normative analysis reaches conclusions based on opinions. (Students will give many different examples.)
Define productive efficiency. Does productive efficiency imply allocative efficiency? Explain.
Productive efficiency is an efficiency criterion that describes a situation in which goods and services are produced at the lowest possible cost. It does not imply allocative efficiency which is a criterion associated with producing goods and services that consumers value most. For example, a manufacturer may be able to produce typewriters at the lowest possible cost of $200, but this does not necessarily mean that consumers are willing to pay $200 for a typewriter.
Which of the following statements is true about profit?

The three fundamental questions that any economy must address are:
What goods and services to produce; how will these goods and services be produced; and who receives them?
The town of Harmonia gives away all 500 tickets to its annual Founder's Day Free Concert-in-the-Park to local residents. Each year, more than 500 people wish to attend the concert, so some of the residents who receive the free tickets sell them for as much as $75 each. Is a transaction where someone pays a resident $75 for a "free ticket" economically efficient?
Yes, it was a voluntary exchange that benefited both parties.
Allison's Auto Art is a company that applies pinstripes to vehicles. Allison's cost for a basic 1-color pinstriping job is $35, and she charges $95 for this service. For a total price of $175, Allison will apply a fancier 3-color pinstripe application to an automobile, a service that adds an additional $40 to the total cost of the package. Should Allison continue to offer the 3-color pinstripe application?
Yes, she still makes a profit by selling the 3-color application.
Consider the following statements: a. Consumers buy more MP3 players from an electronics store that sells MP3 players at a lower price than other rival electronics stores in the area. b.
