Suppose that the total benefit and total cost from a continuous activity are, respectively, given by the following equations: B(Q) = 50 + 18Q – 2Q^2 and C(Q) =40 + 6Q.

(i) What is the equation for the net benefits?

(ii) What is the equation for the marginal net benefits.

(iii) What level of Q maximizes net benefits?

When entry and exit behavior of firms in an industry does not affect a firm's cost structure,

a. the long-run market supply curve must be horizontal.

b. the long-run market supply curve must be upward-sloping.

c. the long-run market supply curve must be downward-sloping.

d. we do not have sufficient information to determine the shape of the long-run market supply curve.

The firm has the following marginal cost function: MC ( y ) = 3 +. 25 y what is the change in producer surplus when the price of y changes from $ 20 to $ 50. (Recall, the change in producer surplus is equal to the new producer surplus minus the old producer surplus).

1.Would it be better to just lower the cost of transit than to get rid of it entirely?

2.if you couldn’t afford to pay the fare price would you do fare evasion?

3.Does the u.s not care if certain countries are crying for help?

4. Why does hurricane Katrina alway happen now?

Eliminating contingent workers will cost the healthcare industry billions of dollars, and some of this burden will fall on privately insured patients as well as government insurance programs. Is it more important to have full-time salaried employees earning living wages with health insurance and pension benefit, or it is more important to keep health cost reasonable for patients? What is your view?

Wardell Company purchased a mainframe on January 1, 2016, at a cost of $40,000. The computer was depreciated using the straight-line method over an estimated five-year life with an estimated residual value of $4,000. On January 1, 2018, the estimate of useful life was changed to a total of 10 years, and the estimate of residual value was changed to $400.

Required:
1. Prepare the year-end journal entry for depreciation in 2018. No depreciation was recorded during the year.
2. Prepare the year-end journal entry for depreciation in 2018. Assume that the company uses the sum-of-the-years' -digits method instead of the straight-line method.

Prepare the year-end journal entry for depreciation in 2018. No depreciation was recorded during the year. (If no entry is required for a transaction/event, select "No journal entry required" in the first account field.)

Journal entry worksheet

• Record depreciation expense.

Note: Enter debits before credits.

A monopolist with marginal cost of MC=Q faces a demand curve of QD = 20 - 2P. This implies that P = 10 - (1/2)Q and that the marginal revenue is MR = 10 - Q. a. Sketch demand, marginal revenue, and marginal cost curves. b. What quantity and price will the monopolist set? c. What quantity and price would the monopolist set if it produced at the efficient market outcome where P=MC? d. Identify the CS, PS and DWL on the graph. e. What is the $ amount of the DWL due to the presence of the monopoly?

1. Suppose a monopolist has constant (average and marginal cost of AC = MC = 8) and faces demand such that Q_D = 100 - P.                                                                                                                     

1. Derive MR curve

(hint: you can calculate TR with Demand curve, then you can drive MR from TR)

2. Calculate a monopolist’s profit-maximizing Quantity and Price
3. Calculate the equilibrium Price and Quantity in the perfectly competitive market
4. Draw all curves (Demand, MR, and MC curves)
5. Calculate Monopoly Profit and Dead Weight Loss (DWL).
6. Comparing the profit-maximizing process and welfare b/w two markets (competitive market and monopoly market) explaining main reason drive these differences and implications from it.

The demand for a monopolist’s product is: P = 40 -2Q; the monopolist’s total cost function is: TC = 8Q + 0.5Q^2.(a)Under free monopoly, what is the numerical value of the dead-weight loss (DWL)? (b) Compute the monopolist’s break-even points and graph in the same diagram, demand (D), marginal revenue (MR), marginal cost (MC) and average cost (AC); in diagrams directly below, graph total revenue (TR), total cost (TC) and profit (pi).(c) Under short-run regulation, what are the market gains?
