The effect of Social Security rules on the age people choose to retire can be critical in evaluating proposed changes to those rules. This research derives a theory of retirement that views retirement as a special type of labor supply decision. This decision is driven by wealth and substitution...

This study analyzes the extent to which an individual's survival expectations influence his or her decision to claim social security benefits at an early age. We find that subjective survival probabilities capture meaningful behavioral responses to incentives for early Social Security claiming...

This paper investigates previously unresearched issues pertaining to the well-known Chilean innovations in Social Security. Previous empirical studies of the Chilean system used aggregate and macro data, without attention to individual heterogeneity. This study uses new household survey data,...

While privatizing Social Security can improve labor supply incentives, it can also reduce risk sharing. We simulate a 50-percent privatization using an overlapping-generations model where heterogeneous agents with elastic labor supply face idiosyncratic earnings shocks and longevity uncertainty....

This paper shows that many common methods of privatizing social security fail to reduce labor market distortions when taxes are second best, challenging a key reason to privatize. Ironically, providing "transition relief" to workers alive at the time of the reform, in an effort to protect their...

Population aging puts significant pressure on social security systems that are based mainly on a pay-as-you-go (PAYG) formula and determined by the political process in which both retirees and future retirees participate. This paper demonstrates that in an economic and demographic steady state,...

Private transfers between individuals or through organized charities are increasingly viewed as an alternative for government social insurance programs. This paper models the incentive effects of government subsidized private transfers and finds that while there is a significant welfare benefit...

It is shown that the inefficiencies created by the “soft” budget constraint, enjoyed by enterprises in Eastern Europe and elsewhere, will continue so long as governments are unable credibly to threaten not to bail out loss-makers. Commitment to a “hard” budget constraint can best be...

This paper examines the impact of social security on welfare. The provision of social security reduces precautionary savings and encourages early retirement. Consequently, it lowers aggregate capital, employment, output, and consumption. On the other hand, it also provides old age insurance....

This paper analyses the role of social safety nets in the form of redistributional transfers and wage subsidies. It is argued that public welfare programs can be viewed as a crime-preventing or disruption-preventing devices because they tend to increase the opportunity cost of engaging in crime...
