Why?A car can be either a “plum” ($11,000) or a “lemon” ($1,000). The owner of a car knows its quality which is unobservable to potential buyers. Assume that, at first, half of the cars in the market are plums and the other half are the lemons. What is the price that a potential buyer is ready to pay? Will the owners of the plums want to sell for this price? What will it imply about the quality and the resulting price of the used cars for sale?What do the two previous What do the two previous examples have in common? examples have in common? two parties interactone of the parties is better informed than the otherthis information has a direct implication on the payoffs that the parties receive from a potential contract between themAdverse SelectionAdverse SelectionThe uninformed side should expect an “average” payoff.Given this, only the “adverse” types will want to “sign” a contract.An Implication for An Implication for Unemployment InsuranceUnemployment InsuranceAssume a private firm is offering unemployment insurance and buying the insurance is not compulsory.What result would you expect?Moral Hazard, examplesMoral Hazard, examplesIf you insure your car against a theft, there is no reason to lock the car.If you are paid a fixed wage and there is no risk of being laid-off, there is no reason to work “hard”If you get sufficiently high unemployment compensation for an indefinite future, there is no reason to look for a job.Moral HazardMoral Hazardtwo parties involved in a contractual relationshipthe unobserved actions of one party affect the payoff (utility) of boththe parties have opposite intereststhe informed party chooses “hazardous” actions to the the uninformed partyUnemployment Compensation, Unemployment Compensation, Adverse Selection, Moral HazardAdverse Selection, Moral HazardAdverse Selection provides grounds for making the Unemployment Insurance compulsory.Moral Hazard restricts the unemployment compensation schemes that can be used.Unemployment Insurance Unemployment Insurance FinancingFinancingPart of the payroll tax (levied on employers) go into the Unemployment Trust Fund.Federal government can levy 6.2% tax on the base ($7,000) yearly salary of a covered employee. 5.4% is credited to the states.
