Use your knowledge about price-searching firms and two-part pricing to advise the company below. A company has a bar and is trying to decide on the cover charge (if any) and price for each drink. It has done a modest regression study in which it asked customers to classify themselves as light drinkers or heavy drinkers and to indicate the number of drinks they would typically consume during the evening. The estimate from the regression study is that a change in the price equal to $1 per drink causes light drinkers to change their consumption on average by 0.5 drinks per night. However, a change in the price of $1 causes heavy drinkers to change their consumption on average by 1.0 drinks per night. For both groups, a typical consumer will not consume anything once the price reaches $9 per drink. (They may instead go to another bar or not go to a bar at all.) Draw a demand curve for a typical light drinker and for a typical heavy drinker on the same diagram. Explain your diagram. Write equations for the curves in slope-intercept form.

If 300 people visit the bar on a typical evening, with 200 people being light drinkers and 100 people being heavy drinkers, draw an overall demand curve for all of the consumers combined. What is the slope and what is the intercept for this demand curve? Write an equation in slope-intercept form. If the marginal cost of making drinks (the alcohol, the bartender's labor, and the amortized cost of purchasing glasses and cleaning them repeatedly) is constant at $5 per drink, and if no cover charge is assessed, what is the best price to charge for drinks? How many drinks would be sold on a typical evening? What would your profits be? If you cut your price by $1 per drink and assess the maximum possible cover charge without causing a typical light drinker to refuse to enter the bar, would your profits improve? How high would the cover charge be? Calculate both the cover charge and your total profits. Would the new pricing increase profit?

Maybe the best price cut is not exactly $1. Write a profit equation. Profits equal to total revenue minus total cost. Total cost equals $5 times the number of drinks sold. Total revenue equals the price for drinks times the number of drinks sold, plus 300 people times the cover charge. The cover charge equals, for a light drinker, the triangle of consumer surplus above the price but below the demand curve for a light drinker. (The area of a triangle equals one half the base times the height.) You will take the derivative of the profit equation with respect to P or Q and set it equal to zero. For example, use the equation for the total demand curve and solve for Q in terms of P. Then in the profit equation substitute in an expression involving P in place of every Q that was in the original profit equation. Now you can take a derivative of profits with respect to P and set the derivative equal to zero. Eventually, you can solve for the exact best P, Q, and cover charge.

Review of the slope-intercept form: Y= a - bX; a = the intercept on the Y-axis and b = the absolute value of the slope (slope=(change in Y)/(change in X)) For a demand curve: P=a-b Q. The intercept on the vertical axis would indicate a price that is so high that the quantity demanded becomes zero. The slope is the ratio of a change in price divided by the change in quantity demanded; the extra credit problem gives you information to determine the slope for a light drinker and the slope for a heavy drinker.

All your answers/discussion should be typed in one essay that is at least 15 lines long (using formal English, correct paragraph and sentence structure, and making sure your ideas flow well from one sentence to another) using Times New Roman, 12 point, double space and 1-inch margins all around. Before submitting the final essay, use the âSpelling & Grammarâ function of the MS Word to correct grammar.

At the end of your essay, provide the full citation record in alphabetical order in your list of references. For examples, visit: http://www.saea.org/wp-content/uploads/2013/08/reference-style-sheet.pdf. Please, note that the list of references does not count toward the minimum required 15 lines. Include your references in the text as â(Smith, 2015)â when citing at the end of a sentence, or âAccording to Smith (2015)â when citing at the beginning of a sentence. For example,

Negative publicity is a key determinant affecting consumersâ buying decisions (Ahluwalia, Burnkrant, and Unnava, 2000).

According to Cawley and Rizzo (2005), pharmaceutical products in the same therapeutic class experienced negative spillover in terms of lost sales.

Note: Most of the future essay questions will build on this essay question and/or the one agricultural commodity that you choose.

. Vouchers to Pay Private School
Tuition
Two conditions that justify government intervention in a market are the presence of external benefits and equity concerns. Both of these issues are present in the case of primary and secondary education in the United States. Think about what education without government education would look like. In the absence of government intervention, all primary and secondary education in the US would be private. Public school districts would not exist. Parents would need to pay private firms (schools) to educate their children.

External benefits

If all education were private, itâs likely that people would buy too little education, from societyâs point of view. External benefits are one reason. When a child is educated, he or she benefits and we expect his or her parents to take those benefits into account when they purchase education. But there are additional benefits to society which parents may ignore. As people become more educated, they are less likely to be unemployed or be criminals and are more likely to volunteer and vote. The presence of these external benefits is an example in support for the government getting involved in education.

Equity

Many families in the United States have low incomes. Among all children in first through twelfth grades in 2001, 46% were from families with incomes below $40,000. Since the cost of private education would be an important share of these familiesâ incomes, most Americans would be concerned about the fairness of relying on markets to decide how much education children receive. Current spending by these families on private education provides some support for this concern. Of all children in private school in 2001, only 25% were from families with incomes below $40,000. Therefore, equity concerns are another example in support for government getting involved in education.

Providing vs. producing education

Most economists think external benefits and equity concerns justify government intervention in education. But it is important to distinguish between government production of education and other forms of government intervention. At the level of elementary and secondary education, K- 12 education, government intervention today mostly means production of education by local school districts. To benefit, children must attend public schools. But this is not the only form intervention could take.
There are other markets where government intervention takes the form of subsidizing peopleâs access to productsâthink of financial aid to college students, for example. Many people in the US think that government should move from producing education to subsidizing access.

One form that subsidy could take is government providing vouchers to parents. Parents would use the voucher to help pay for their childâs education in a private school. After it receives the voucher, the school would turn it in and be paid by a local or state government.

Today there is a lively debate between people who think K-12 education should be delivered publicly and people who think quality and efficiency would be higher if government provided vouchers and the education was delivered by private schools. Some of these quality and efficiency arguments can be based on material we covered this week. Price competition between private schools will pressure each one to produce efficiently. Competition for students will lead private schools to offer programs of interest to parents and their children.

Answer the questions below and make use of the sources supplied. Be sure to cite you sources in your answers.

1. Explain whether a potential exit by students with vouchers will lead to the improvement of public schools. 2. Discuss whether the implementation of vouchers will lead the best students to leave public school, which could lead to a decline in education for the students left behind in the public schools. 3. Consider what might happen to the students who use vouchers to leave public schools in order to attend private schools. How might their academic performance change as a result of switching? 4. Finally, think about the impact of a voucher system on the students in an urban setting. Describe whether all families would have an equal opportunity to access education.

Your final product will be a paper that: ? Addresses each of the four questions above in total. ? Is APA formatted. ? The body is to be 2 pages minimum.

The requirements for your assignment are: 1. Answer each question fully 2. Define the overall subject of each question. 3. Cite at least three (3) resources from this weekâs materials.
