  5. 10.2 The Ideal World of First Best Price (P) = Buyers’ private marginal benefit (MB) = Social marginal benefit (SMB) = Sellers’ private marginal cost (MC) = Social marginal cost (SMC)

  6. 10.3 The Realistic World of Second Best Incentive Distortions MB ≠SMB MC ≠SMC Externalities Spillover effects

  8. Government Polices toward Externalities • Two Approaches • The tax-or-subsidy approach A. C. Pigou • The property-rights approach • Ronald Coase

  9. Arthur Cecil Pigou 1877-1959 Ronald H. Coase The Nobel Prizes 1991

  10. The Specificity Rule 针对性(专向性)规则 It is more efficient to intervene directly at the specific source of distortion.

  11. Implications of the specificity rule for trade policy In a second-best world, a trade barrier can be better than doing nothing, but some other policy instrument is usually more efficient.

  12. 10.4 Promoting Domestic Production or Employment Positive Externalities • Promoting Domestic Production

  13. Promoting Domestic Employment in an Industry Employment subsidy is better than trade barrier.

  14. 10.5 The Infant Industry Argument 幼稚产业论

  15. Friedrich List 1789-1846 Alexander Hamilton 1755–1804

  23. The basic elements of the political analysis • The size of the losses for the losers from protection (Bc: Area a+b+d ), and how many individuals are in the group of losers (Nc).

  24. The basic elements of the political analysis • Individuals’ reasons for taking positions for or against protection. • Bp or Bc √ • Sympathy • Ideology

  25. The basic elements of the political analysis • Types of political activities and their costs. • Political institutions and the political process. • Direct voting • Representative voting

  26. When Are Tariffs Unlikely ? • Direct Democracy • Direct vote by individuals on each tariff • Voting is costless • Each person votes based on his direct interest. • Nc > Np, No Tariff.

  27. Representative Democracy • Each group is willing to devote all its gains (Bp or Bc) to political activities. • Politicians make decisions according to the amount of lobbying or contributions received. • Bc > Bp, No Tariff.

  28. When Are Tariffs likely ? • Lobbying cost per individual is fixed Benefits • producers: Bp/Np (high) • Consumers: Bc/Nc (low) If Bc/Nc < Fixed cost, Tariff will be OK.
