I need an urgent help with these questions. Could you please show step by step how to solve these questions? It is really important to me. Thanks in advance. 1. A monopolist is the only seller of a good whose demand is; Q = 1000 - 10p. The monopolist's cost function is; C = 0.1Q? + 10,000. 1) (a) How much does the monopolist produce, and at what price does it sell? (b) Show on a well-labelled diagram (at least approximately to scale) the relevant lines for working out the answer to the previous question. (c) What is the monopolist's profit? (d) Shade producer surplus on the diagram. (e) How much is producer surplus? (f) Shade the deadweight loss on the diagram. 2. (5+7+5=17 pts) Consider how the war in Ukraine has affected the world wheat market: Ukraine is a major wheat exporter, and was in the process of exporting the winter harvest when the war began. In most of the wheat-growing world, April is a major planting month, with the harvest following in September. (a) Use a diagram to show the short-run (immediate) effect of the war on the world wheat market - by this I mean the market for wheat delivered in March-June. Ignore changes in the price of potash. Brief accompanying text should justify your diagram. (b) Use a diagram to show the medium/long run effect of the war on the world wheat market outside Ukraine - by this I mean the market for wheat delivered in September. Ignore changes in the price of potash. Brief accompanying text should explain why your diagram differs from the previous one. (c) Now consider the fact that the war has also led to an increase in the price of potash, an input to fertilizer used in wheat cultivation. Show the effect of this on the previous diagram and explain with brief text. 3. The world production possibility frontier (PPF) is given by 5000 = Q2X + 25Q2y (3) The utility function for the consumers is U= QxQy (4) I have calculated for you the point on the PPF at which the world will produce and consume, which is Qx = 25, Qy = 10. (a) Draw the PPF, labelling three points with numerical values including (25,10). Arithmetic tip: Sqrt5000 = 70.7. (b) Add to your graph to show what determines the point at which the world will produce and consume. (c) Show how we can learn the ratio of the price of the two goods from the graph. (d) What is the ratio of the prices of the two goods
