A、T/Q B、T+Q C、TxQ D、(TxQ)/Q\n简答题\n For a good that is taxed, the area on the relevant supply-and-demand graph that represents government’s tax revenue is ( ). A、smaller than the area that represents the loss of consumer surplus and producer surplus caused by the tax B、bounded by the supply curve, the demand curve, the effective price paid by buyers, and the effective price received by sellers C、a right triangle D、a triangle, but not necessarily a right triangle\n简答题\n A tax levied on the sellers of a good shifts the ( ). A、supply curve upward (or to the left) B、supply curve downward (or to the right) C、demand curve upward (or to the right) D、demand curve downward (or to the left)\n简答题\n Other things equal, the deadweight loss of a tax ( ). A、decreases as the size of the tax increases B、increases as the size of the tax increases, but the increase in the deadweight loss is less rapid than the increase in the size of the tax C、increases as the size of the tax increases, and the increase in the deadweight loss is more rapid than the increase in the size of the tax D、increases as the price elasticities of demand and/or supply increase, but the deadweight loss does not change as the size of the tax increases\n简答题\n Refer to Figure 8-3. The equilibrium price before the tax is imposed is ( ). A、P1 B、P2 C、P3 D、P4\n简答题\n Refer to Figure 8-2. The imposition of the tax causes the price paid by buyers to ( ). A、decrease by 3 C、decrease by 5\n简答题\n As the tax on a good increases from 2 per unit to $3 per unit and so on, the ( ). A、tax revenue increases at first, but it eventually peaks and then decreases B、deadweight loss increases at first, but it eventually peaks and then decreases C、tax revenue always increases, and the deadweight loss always increases D、tax revenue always decreases, and the deadweight loss always increases\n简答题\n Total surplus with a tax is equal to ( ). A、consumer surplus plus producer surplus B、consumer surplus minus producer surplus C、consumer surplus plus producer surplus minus tax revenue D、consumer surplus plus producer surplus plus tax revenue\n简答题\n The decrease in total surplus that results from a market distortion, such as a tax, is called a ( ). A、wedge loss B、revenue loss C、deadweight loss D、consumer surplus loss\n简答题\n Refer to Figure 8-1. Suppose the government imposes a tax of P' - P'''. Total surplus before the tax is measured by the area ( ). A、I+Y B、J+K+L+M C、L+M+Y D、I+J+K+L+M+Y\n简答题\n A 2 B、downward by less than 2 D、upward by less than $2\n
