Great Wall Pizzeria issued 10-year bonds with the face value of $100 one year ago at a coupon rate of 6.20 percent. Coupons are paid semiannually. If the YTM on these bonds is 7.4 percent per annum with a semiannual compounding frequency, what is the current bond price?

Suppose that a perfectly competitive firm is currently producing 100 units of output. If the short-run marginal cost of producing the 100^th unit is greater than the price at which that unit can be sold, how must this firm alter its labor input in order to maximize profit

A cruise line estimates that it can sell 3,400 tours to Alaska at a price of $900 each, but it will lose 100 sales for each $50 increase in its price. Let p be the price and q the number of tours sold.

(a) Write q as a linear function of p.

(b) Write the revenue R as a function of p and find the marginal revenue with respect to p (i.e., the rate of change of R with respect to p).

(c) Suppose it costs $400 per passenger to operate the tour. Write the cost as a function of the price p and find the marginal cost with respect to p.

(d) Find the marginal profit with respect to p.

(e) The company priced its tour at $1,050 last year. If it increases the price this year, will it increase or decrease its profit? Explain your answer.

(f) Answer the same question and explain your answer if last year’s price was $1,550.

Suppose the inverse demand for a product produced by a single firm is given by P = 200 − 5Q and this firm has a marginal cost of production of MC = 20 + 2Q.

a. If the firm cannot price-discriminate, what is the profit-maximizing price and level of output for this monopolist? What are the levels of producer and consumer surplus in the market? What is the deadweight loss?

b. If the monopolist can practice perfect price discrimination, what output level will it choose? What are the levels of producer and consumer surplus and deadweight loss under perfect price discrimination?

c. Suppose that the monopolist’s marginal cost curve is now MC = 20. If the monopolist cannot perfectly price discriminate but can distinguish between students (with a demand curve of P = 100 − 10Q) and non-students (with a demand curve of P = 300 − 10Q), what will be the price it is charging to students and non-students? What will be the quantity it is selling to students and non-students?

1. The global demand for cocoa can be represented with the following equation:

P=50 - 0.25Q, where P is the price (dollars per 100 lbs.), and Q is quantity. Furthermore, assume that cocoa can be produced at a constant marginal and average cost of $10 per unit of Q.

Cocoa producers have formed a cartel, aimed at realizing the monopoly price for cocoa.

Given the demand equation and marginal cost specified above, what is the monopoly price and quantity?

The monopoly sets MC=MR for profit maximization

MR = twice the slope of the demand curve

MR = 50-0.50Q

MC = 10

50-0.50Q = 10

50-10 = 0.50Q

Q = 40/0.50 = 80

P = 50-0.25*80 = 30

1. In perfect competition, the market price will equal marginal cost. What’s the competitive price and quantity and how does that compare to the monopoly price and quantity?

Q. The example uses the following data for 2007 :

P_G = wholesale price of natural gas ($ per 1000 cubic feet)

P_O = average price of a barrel of crude oil = $50,

Production and consumption of natural gas were 23 trillion cubic feet,

Supply of Natural Gas (trillion of cubic feet): QS = 15.90 + 0.72P_G + 0.05P_O

Demand for Natural Gas (trillion of cubic feet) QD = 0.02 – 1.8 P_G + 0.69P_O

a. Find the equilibrium price for natural gas

b. Suppose the regulated price of gas were $7.00 per thousand cubic feet instead of $3.00. How much excess demand or supply would there have been?

b. Suppose the market for natural gas remained unregulated.   If the price of oil increased from $50 to $100, calculate the cross- price elasticity of natural gas with respect to crude oil.

The following information is available for the employees of Webber Packing Company for the first week of January Year 1:

1. Kayla earns $25 per hour and 1½ times her regular rate for hours over 40 per week. Kayla worked 50 hours the first week in January. Kayla’s federal income tax withholding is equal to 8 percent of her gross pay. Webber pays medical insurance of $85 per week for Kayla and contributes $48 per week to a retirement plan for her.
2. Paula earns a weekly salary of $1,150. Paula’s federal income tax withholding is 19 percent of her gross pay. Webber pays medical insurance of $100 per week for Paula and contributes $100 per week to a retirement plan for her.
3. Vacation pay is accrued at the rate of 2 hours per week (based on the regular pay rate) for Kayla and $85 per week for Paula.

Assume the Social Security tax rate is 6.0 percent on the first $110,000 of salaries and the Medicare tax rate is 1.5 percent of total salaries. The state unemployment tax rate is 5.4 percent and the federal unemployment tax rate is 0.6 percent of the first $7,000 of salary for each employee.

c. Prepare the journal entry to record the payment of the payroll for the week. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field. Do not round intermediate calculations. Round your answers to 2 decimal places.)

Journal entry worksheet
