  20. Policy responses to public good problems? • Government provision • Government funding but private provision • …

  21. Information asymmetry Search goods: consumers can determine its characteristics with certainty prior to purchase Experience goods: consumers can determine its characteristics only after purchase

  25. Mandatory Testing for Mad Cow Disease in Cattle Government Suit against Tobacco Firms (over hiding health impacts) US Subsidies of Lumber Production and Exports. Government Funding of Stem-Cell Research. Affirmative action policies. Rules to protect wetlands from development. Establishing a certification for organic foods. Should the Federal Government pay Amtrak’s deficits (~$3 Billion) Is this a response to a Market Failure?

  32. Information asymmetries Policy response:

  33. Policy responses to insufficient information • Civil laws (consumer protection regulation) • Directs information provision (e.g. accreditation, licensing) • Indirect information (encourage consumer reports)

  34. When should government intervene to correct asymmetric information? • Public interest in quality of good (food security vs shoes) • Nature of the product (house vs chocolate bar) - frequency of purchase - cost of wrong information
