The pipeline industry has approximately 100 companies, as compared to the motorcarrier industry with more than 50,000. What are the underlying economic causes  for this difference, given the fact that they both carry approximately the same volume of intercity ton-miles?

For the case of an industry that you know well, describe the extent to which firms in that industry are open to competition from international

Need help on this to pass my class.

The per-week (inverse) demand for use of the Øresund Bridge between Denmark and Sweden is P = 13 − 0.15Q during peak traffic periods and P = 10 − 0.1Q during off-peak hours, where Q is the number of cars crossing the bridge in thousands and P is the toll in euros. If the marginal cost of using the bridge is MC = 5 + 0.2Q, what is the optimal peak load toll and off-peak load toll for crossing the bridge?

Problem 3 Squeak eClean produces commercial sanitizer used to clean tanker trucks that haul liquid food products such as milk. This sanitizer a commodity like any other and at the wholesale level, there are many domestic and foreign producers that compete vigorously. Suppose you have the following estimated market demand and supply functions for the sanitizer. Qd=248.08 +2.2Y – 0.6Pc+ 1.2 Ps − 4P Qs = 10 +2P In these equations, Q measures output in gallons per month (in 1,000's), P is the price per gallon of the sanitizer, Y is annual average household income (in 1,000's), Pc is an index of commodity prices, and Ps is the average price per gallon of other types of sanitizer. After gathering the latest data, you find that average household income is $36,400, the current level of the commodity price index is 110.6, and the average price per gallon of other types of sanitizers is $48.50. a. Find the current equilibrium price and quantity in this market. b. Find the equilibrium price and…

Consider an industry of 2 firms with the following marginal abatement cost functions: MAC1 = 300 – 30e1 MAC2 = 500 – 20e2 1. Calculate the total abatement cost for both firms of reaching the aggregate emissions level of 20 tons via the tax? Don’t include the tax payments. Firm 1’s Total Abatement Cost $_____ Firm 2’s Total Abatement Cost $______2. Suppose you want to limit aggregate emissions to 20 tons with a competitive tradeable emissions permit system. If Firm 1 is given 5 permits and Firm 2 is given 15 permits, after trading how many permits will each firm end up with?Firm 1:____Firm 2:____ Please give correct information, I been getting a lot of wrong answer so far.

IMPORTANT: The owner chooses to adopt a new technology that changes the cost function to C(q)=4q^2+2q+64. All the competitors follow her lead and choose to adopt the same technology and have the same cost function. They are all price-takers. From now on, use this cost function.

Problem 2: Presently, APlus Transport and Big Movers are the only suppliers of services that haul heavy construction equipment between jobs within the Midwest. No other suppliers have the equipment necessary to perform the service. The market inverse demand for these hauling services is given below. P = 4,030-4Q where P is price per trip and Q is total number of trips per year. For simplicity, also assume that neither firm has fixed costs. From company records, you are given the following variable cost function for each firm: a. C. TVC = 300 TVCB = 80QB b. Calculate the Cournot market equilibrium price-output solutions for each firm including their respective profits. d. Assume these two competitors operate as a two-firm Cournot duopoly. Find the reaction functions for each firm. Suppose Big Movers shuts down operations so that APlus now has a monopoly in this market. What is the price, quantity, and profits for APlus after this change? Summarize the results of your findings over the…

How does a cap-and-trade program deliver a minimum-overall-cost allocation of abatement responsibility? How is required abatement for each firm dictated within a cap-and-trade program? What information is conveyed by the equilibrium price of the permits being traded?  How have recent cap-and-trade programs been modified to prevent market disruptions from resulting in either price spikes or extremely low prices?
