Advisor: Ellen McGrattan. 1 computer file (PDF); vii, 121 pages.This thesis studies the welfare impact of Social Security reform through case studies of reforms done in Chile in 1981 and 2008. Chapter 2 presents the literature related to the topic. Chapter 3 uses Chilean micro-data in order to measure how workers substitute between formal work, informal work, and home production. These estimates will be used in subsequent chapters. Chapter 4 studies the 1981 reform in which Chile moved from a pay-as-you-go Social Security system to a program of private, individual retirement accounts. Chapter 5 studies a secondary reform from 2008 which amended the minimum pension available to those workers who do not save sufficiently for their own retirement.enChileHome ProductionInformalitySocial SecurityThesis or Dissertation
