Her insurance company pays the remaining $420. If the market demand equations: QD=1000-P. (1) Solve for the equilibrium price and the equilibrium quantity if each procedure has a price of $570.(4%) (2) If the government imposes a price ceiling of $450 and subsidizes $120 in this , then how much producer surplus will be in the market?(3%) (3) Show the quantity of procedures demanded if consumers pay only $150 per procedure.

The government wants to reduce pollution to 120 units, so it gives each firm 30 tradable pollution permits. ┌──┬────────────┬──────────────────┐ │Firm│Initial Pollution Level │Cost of Reducing Pollution by 1 Unit│ ├──┼────────────┼──────────────────┤ │ A │ 70 units │ $20 │ ├──┼────────────┼──────────────────┤ │ B │ 80 units │ 25 │ ├──┼────────────┼──────────────────┤ │ C │ 60 units │ 15 │ ├──┼────────────┼──────────────────┤ │ D │ 50 units │ 10 │ └──┴────────────┴──────────────────┘ (1) Who sells permits and how many do they sell? Who buys permits and how many do they buy? What is the total cost of pollution reduction to this situation?(9%) (2) How much higher would the costs of pollution reduction be if they permits could not traded?(3%) 七、(6%)中國國防部2013年11月公告釣魚台列嶼劃入「東海防空識別區」範圍。過去釣 魚台列嶼是劃入日本防空識別區內，中國此次自行將釣魚台列嶼劃設到東海防空識 別區內，勢將拉高日本與中國之間的衝突與對立。請以公有資源所學說明應如何解 決釣魚台列嶼的主權問題？ 八、(10%)Please answer the following quetions: (1) Explain why the marginal-cost curve crosses the average-total-cost curve at its minimum?(5%) (2) If the city government implements a lump-sum tax of NT$5,000,000 on each producer of cars.
