摘要: How much does the current social security system redistribute from rich to poor? We propose alternative concepts of well-being that can be used classify individuals poor, and we show how redistributes differently under each concept. use PSID estimate lifetime wage profiles actual earnings year for a sample 1778 individuals, mortality probabilities calculate expected payroll taxes benefits. For given set “facts” about net flows experienced by individual, measured progressivity depends on many assumptions. This paper attempts capture quantify all data characteristics relevant determine individual’s “income” several definitions. then definition income poor security.
