Answer all parts (a)-(g) of this question.Mette has started Mersea Oysters. She aims to export oysters to Germany where she acts as aprice taker. After a couple of nights of calculations she believes that her cost function is givenby C(q) = 100 + 6q + 2q2, where q denotes kilos of oysters harvested. The market price shewill face in Germany is 50 per kilo.(a) [4 marks] Derive Mette’s marginal cost function.(b) [7 marks] Use your result from (a) to determine the profit-maximizing output level.(c) [7 marks] Explain in words why the supply function for a price taker is the same as themarginal cost function.(d) [8 marks] Calculate Mette’s profit. Illustrate marginal cost and profit in a diagram.(e) [8 marks] Now instead assume that the price is 22. Should Mette produce at this price?(f) [8 marks] Assume again that the price is 22 but that the fixed cost of producing (100) issunk and was taken in the previous period. Should Mette produce at this price in this case?(g) [8 marks] Assume again…
If company A manufactures t-shirts and sells them to retailers for US$9.80 each.It has fixed costs of $2625 related to the production of the t-shirts, and the production cost per unit is US$2.30. Company B also manufactures t-shirts and selll them directly to consumers.The demand for its product is p = 15-x/ 125, its production cost per unit is US$5.00 and its fixed cost are the same as for company A . How many t-shirts must company B sell to maximise its profit?

2) Alcem Pte. Ltd. Is in the business of manufacturing cement. The company sets up a 1 million ton plant. The total cost of setting up the plant is $100 million. The cost of Raw material/ Labor etc for producing 1 ton of cement is $ 40. The price of Cement is $80 per ton. Assume a Capital Cost of 10% (which is also its opportunity cost) a) What is the breakeven quantity of cement for Alcem? 250,000 tons b) In the short run, below what price should Alcem shut down? $40 c) If Alcem produces and sells 1 million tonnes of Cement, what is the Economic Profit it is making? $30 million d) If there are no barriers to entry in this business what would you expect
One of the main concerns in the coronavirus outbreak is the spreadof the virus during air travel. To avoid the risk of spreadingvirusand eliminate concernsduring air travel, airlines started to circulate fresh air in the airplane cabins every 3 minutes. For this purpose, air needs to be compressedfrom outside to inside the airplane cabinand conditioned for passenger comfort and safety. Calculate the average cost of this new implementation to Turkish Airlines for one of its national flights assuming that the energy costs 2 $ per kW hr?
asumming Two firms produce a homogeneous good and compete in prices. Consumers buy the good from the firm that charges the lower price. In case the price charged by the two firms is the same, the firms split the demand. The linear demand curve for the product is given by Q=100A−P. Bothfirmshavethe same constant marginal cost of 40. (a) [10] Plot the best response functions on the axes, recording p1 on the horizontal axis and p2 on the vertical axis. Label the two best response functions. Make sure that you explain what the prices in equilibrium (and profits) for the two firms are when they choose prices simultaneously and interact only once. Assume now that both firms choose simultaneously but interact an infinite number of times. Each firm discounts the future based on the discount factor 0 < δ < 1. (b) Show under which range of δ collusion is an equilibrium in this market. Explain the various steps. (c) Repeat the analysis in (b), but assuming now that the two firms compete in…

SITUATION3: Under the data collected from the office of Department of Transportation and DPWH over the last 5 years indicate that for each fatality, there are 40 non-fatal injury accidents ($1500 present cost each) and 300 property damage accidents ($2000 present cost each). What is the breakeven value of statistical Me (VSL) needed to justify a highway project if i is 8%? The death rate on a particular three-lane road is 8 per 100 million vehicle-miles. Adding a lane would reduce this to 5 per million, and other accidents would cost $1.5M per mile to build, and annual maintenance would be 3% of the first cost. Assume that the lane would last 40 years. The road carries 10000 vehicle per day. Use reduction factor of 3/8 for all accidents. (Non-CE students no need to answer this item).
Problem 2: As a building designer, you have been asked to analyze and select the best window frame type alternative-either aluminum or steel. The project is located in a remote area, and the nearest industrial area hosting steel and aluminum windows frames manufacturers is 250 km away. All project windows are identical, and the circumference of the window frame is 6.2 meter. A crew of two labors is required to manufacture one steel frame. It takes 2.5 hours to manufacture the first window every day, and the learning rate is 0.9. The number of production units is per day is limited to 8. The weight of steel is 12 kg per meter, and the weight of aluminum is 4.5 kg per meter. The cost of steel is 0.4 OMR per kg and the cost of aluminum 1.1 OMR per kg. If 45 windows frames are required for the project, the crew cost is 3 OMR per hour for steel frames and 3.6 for aluminum frames, and the transportation, price is 0.01 OMR per kg per 50 km, which alternative would you select?
