Almost all papers on the feasibility of a Pareto improving transition path from a Pay-as-you-go to a fully funded system employ lump sum or wage taxes for financing the compensating transfers. This paper focuses on this issue by using consumption or proportional income taxes and applying a...

This paper examines the labor force activity and timing of benefit claims of workers aged 65-69 in response to the removal of the retirement earnings test in 2000. We use the 1 percent sample of longitudinal Social Security administrative data that covers the period from 4 years before to 4...

In a recent paper (2006), Pestieu et.al. showed that the optimal payroll tax rate for the PAYG pension in an open large economy should increase as number of countries increases. This rather counterintuitive result -increasing the factor mobility makes redistribution easier-depends on a crucial...

It is argued that a PAYGO system may have useful allocative functions in that it serves as an insurance against not having children and as an enforcement device for 'rotten kids' who are unwilling to pay their parents a pension. It is true that the system has a moral hazard effect in terms of...

This paper quantifies the effects of social security on capital accumulation and wealth distribution in a life cycle framework with altruistic individuals. The main findings of this paper are that the current U.S. social security system has a significant impact on capital accumulation and wealth...

For all its rapid economic and military growth, China may have a crucial weakness in its grossly underfunded retirement system for the largest national population on earth. Currently, the implicit pension debt in China is around $1.5 trillion, a liability that primarily rests on the country's 31...

Although elderly men and women share many of the same problems as they age, their lives are likely to follow different courses. Women are more likely than men to live into old old-age and are more likely to spend part of their young old-age caring for husbands or parents. By providing this...

Much of the existing literature on social security has taken the extreme assumption that individuals have little or no altruism; this paper takes an opposite assumption that there is full two-sided altruism. When households insure members that belong to the same family line, privatizing social...
