Assume that the market for a good is in equilibrium at a price of $20 and a quantity of 100 units. after the government imposes a $5 per-unit excise tax on the good, the price that buyers pay for the good increases by $3. which of the following are possible values for the government tax revenue and deadweight loss in the market?

Many potential buyers value high-quality used cars at the full-information market price of € p1 and lemons at € p2. a limited number of potential sellers value high-quality cars at € v1 ≤ p1 and lemons at € v2 ≤ p2. everyone is risk neutral. the share of lemons among all the used cars that might be potentially sold is € θ . suppose that the buyers incur a transaction cost of $200 to purchase a car. this transaction cost is the value of their time to find a car. what is the equilibrium? is it possible that no cars are sold
