Consider a market with Qd=240 – 6p and Qs=2p. a. What’s consumer surplus? in the solution it says 1. Qd = Qs gives that 240 – 6p = 2p. Simplifying the equation yields 8p = 240, which gives p*= 30. Plugging P*=30 into either demand or supply gives Q*= 60. CS = 1⁄2 * (40 - 30) * 60 = 300. Where did they get 40 from?

The demand for a good is given by QD = 99−3P and the supply by QS = 2P + 4. The market for this good is in equilibrium. Now, the government introduces a tax of $5 per unit to be paid by the producers. How large is the consumer surplus, producer surplus, and total welfare generated by this market after the introduction of the tax? Show your calculations. Sketch the market diagram and label all relevant prices and quantities.
1. The old demand was Qd = 180 – 2P. Due to good weather, there is an increase in the demand for the good. The new demand equation is Qd = 190 – 2P. The government is trying to decide between two options. Maintain the number of quotas and let the market adjust, or Maintain the price support and increase the number of quotas. a. Suppose that the government decides to maintain the number of quotas and let the market adjust. Calculate the following: Price observed in the market The consumer surplus The producer surplus Deadweight loss b. Suppose now that the government decides to increase the number of quotas available to 72 units, but it keeps the price support at the current level of $72. Calculate the following: The consumer surplus The producer surplus Deadweight loss
Suppose that the market demand curve for a good is given by D=80-2P-2I, where D is the quantity demanded, P is the price of the good, and I is consumer income in thousands of dollars.
