We construct a Blanchard-style overlapping generations model consisting of long-lived individuals who have uninsurable idiosyncratic risk resulting from uncertain retirement periods and medical costs in retirement. Without social insurance, such individuals must save for these eventualities. We...

We construct a unified overlapping-generations (OLG) framework of equilibrium growth that includes the Blanchard “perpetual youth” model, the Samuelson model, and the infinitely-lived representative agent growth model as limit specifications of a “realistic,” two-parameter survivorship...

We examine the impact of a stylized pay-as-you-go (PAYGO) Social Security program in an economy of overlapping generations with equilibrium growth. We adopt realistic mortality and other demographic assumptions and allow for the presence or absence of full life annuities. In all cases we find...

This study attempts to provide benchmarks of North Korean institutional changes that signal the increased role of markets, looking at macroeconomic management, introduction of market-supporting policies, and provision of market-supporting infrastructure. The weight of the evidence indicates that...

Although the Parks (1967) estimator for a SUR model with AR disturbances is efficient both asymptotically and in small samples, Kmenta and Gilbert (1970) and more recently Beck and Katz (1995) note that estimated standard errors tend to be biased downward as compared with the true variability of...

This paper describes the relationship between a youth’s residence at age sixteen and the likelihood he eventually enlists in the military. Data from the NLSY97 show that white youths raised in two parent families are less likely to enlist than those raised in other family structures. Black...
