Unemployment insurance (UI) is the mostcommon public income support program for the unemployed indeveloped countries.1 In these countries, it typicallyoffers good protection: it covers the majority of employedpersons, irrespective of occupation or industry, andprovides adequate smoothening of consumption patterns. Forexample, studies on the U.S. find that the welfare ofbenefit recipient households is on average only 3-8 percentlower than the welfare of otherwise identical households,and that in the absence of unemployment insurance, averageconsumption expenditures would fall by about 20 percent. Inthe last decade, UI programs have been introduced intransition countries, and their use in developing countriesis on the rise as well.
