This paper aims to explore the institutional traits of the federal employees pension system in the United States and the direction of its reform. Currently the United States has two systems of the federal employees pension. One is CSRS, the other is FERS. The former was firstly introduced in 1920 as a generous DB pension well before the establishment of the Social Security System(OASDI). What led to the latter, FERS was the Social Security Amendment Act of 1983 and Federal Employee Retirement System Act of 1986. The crucial difference between the CSRS and the FERS is the contrasting characteristic of their relationships with OASDI. The CSRS has just one source of retirement benefit(DB pension) without OASDI benefit, whereas the FERS has three sources(OASDI benefit, basic annuity(DB), DC typed TSP benefit). When it comes to FERS, what matters most is TSP(Thrift Savings Plan).
