ECON 201 Lecture Notes - Lecture 9: Demand Curve, Marginal Utility, Deadweight Loss
Document Summary
Tarrif a tax on imported goods. Imports = q1d q1s at pw. Imports at pw + t: imports = q2d q2s. Therefore with tariff we have fewer imports. Inefficient surplus loss of surplus is a is lost (e and g), deadweight loss of the tariff. Tariff is disntance between pw and pw+t (tariff rev = tariff per unit * Infant- industry argument protect them while they get started but after a while stop because they won"t make it anyway. Chapter 10 externalities. Take red line from second graph and move it to first graph becomes parallel gap between is mec. Marginal social cost msc = mpc + mec. S = mpc (marginal private cost) Social optimum is efficient, qmarket is inefficient. D = mb (marginal benefit curve) Steel company should take cost ofpollution into account or made to do so. Would then operate at where social cost and demand curve intersect (b = social.
