3. The minimum wage is an example of a government price ceiling and results in a reduction in unemployment.
4. Efficient production can be carried out anywhere on or beyond the production possibilities frontier.
5. An economist would predict that if the government imposes price controls on medical care, the result will be an increase in the supply of affordable care in the United States.
6. Black markets can generally be eliminated when price ceilings are enacted.

In the years leading up to the 2008 recession, General Motors, Ford, and Chrysler (the big three) were producing new vehicles in excess of market demand. This led to large inventories on car dealer’s lots across the United States. At the same time, under the absorption costing method, profits were rising and executives at these three companies were achieving their short-term incentive targets. Explain how firms can increase net operating income simply by producing more units under the absorption costing method. Identify and discuss the ethical issues involved in the decision top executives in the big three auto companies made about the level of production.

Unions were tremendously successful in the late 19th and early 20th centuries because many manufacturing workers were low-skilled and spent most if not all of their working lives in a single manufacturing plant and with the same company. Today, the American economy is far more knowledge-based. Think about what compensation strategy would prove more effective today: the incentive-based, more knowledgeable worker, or the lower wage-base with more self-service? Based on what approach you choose, how would organized labor be affected? Is a knowledge-based economy yet another reason why unions continue to witness reduced membership in the United States?

According to the University of Nevada Center for Logistics Management, 6% of all merchandise sold in the United States gets returned. A Houston department store sampled 80 items sold in January and found that 10 of the items were returned.
a. Construct a point estimate of the proportion of items returned for the population of sales transactions at the Houston store.
10/80 = .125
b. Construct a 90% confidence interval for the proportion of returns at the Houston store.
????,???? (to 4 decimals)
c. Is the proportion of returns at the Houston store significantly different from the returns for the nation as a whole? Provide statistical support for your answer.
H0: p0 = 0.06
Ha: P0? 0.06
Z- Value = ?????
P-Value = ?????

You are planning on analyzing data that show the incidence of
terrorist events across the United States. Write a brief paragraph
that includes the following information:
i.) provide examples of different variables at the nominal,
ordinal, and ratio scale variable that you would encounter in this
context,
ii.) explain what type of central tendency (mean, median, or mode)
you would use to best represent each of the three variables in your
example, and
iii.) describe for which variable(s) you would be able to compute
and interpret a standard deviation.
NOTE: Be sure to provide enough detail in your descriptions so that we can determine how each of your three variables are measured.

1. One common argument for imposing so-called sin taxes is the social goal of reducing demand for such products. Using cigarettes as an example, is there a segment of the population that might be sensitive to price and for whom high taxes might discourage purchases?
2. Kobe strongly dislikes SUVs and is appalled that so many are on the road. He proposes to eliminate the federal income tax and replace it with a $50,000 annual tax per SUV. Based on the number of SUVs currently owned in the United States, he estimates the tax will generate exactly the amount of tax revenue currently collected from the income tax. What is wrong with Kobe’s proposal? What type of forecasting is Kobe likely using?

Developments after the global financial crisis moved the US away from being one of the most free-market economies in the world toward an economy with much more active and stronger government involvement (e. g., the “Patient Protection and Affordable Care Act,” commonly known as “Obama-care,” requires employers to spend more on health care, including smaller firms). What implications does this shift in the political and economic environment in the United States have for large firms (such as GE or IBM) versus small firms (mom and pop entrepreneurs and technology startups)? How does this change the competitive landscape and affect a firm’s strategy formulation and implementation?
