In the presence of uncertain lifetimes, social security has the characteristics of an annuity: a consumer pays a tax when young in exchange for receiving a social security benefit if he survives to be old. If consumers have identical ex ante mortality probabilities, then a fully funded social...

The social security program now provides a constant real benefit throughout each retirees lifetime. This paper examines whether total welfare would rise if benefits were lower in early retirement years (when most individuals have some saving with which to finance consumption) and higher in later...

During the financial crisis, life insurers sold long-term policies at deep discounts relative to actuarial value. The average markup was as low as -19 percent for annuities and -57 percent for life insurance. This extraordinary pricing behavior was due to financial and product market frictions,...

This paper evaluates the extent of adverse selection in life insurance and annuities in international markets, for both group and individual products. We also compare results with prior analyses of adverse selection in international annuity markets, focusing on the US, the UK, and Japan. Our...

This paper provides an empirical estimate of price' and risk' elasticities of demand for term life insurance for those who purchase some insurance. It finds that the elasticity with respect to changes in premiums is generally higher than the elasticity with respect to changes in risk. It also...

One goal of government health insurance programs is to improve health, yet little is known empirically about how important such government interventions can be in explaining health transitions. We analyze the child mortality effects of a major health insurance expansion in Costa Rica. In...

Life insurers use accounting and actuarial techniques to smooth reporting of firm assets and liabilities, seeking to transfer surpluses in good years to cover benefit payouts in bad years. Nevertheless, these techniques been criticized as they make it difficult to assess insurers' true financial...

The conventional wisdom dating back to Yaari (1965) is that households without a bequest motive should fully annuitize their investments. Numerous market frictions do not break this sharp result. We modify the Yaari framework by allowing a household's mortality risk itself to be stochastic....

We develop a macroeconomic model with physical and human capital, human capital risk, and limited contract enforcement. We show analytically that young (high-return) households are the most exposed to human capital risk and are also the least insured. We document this risk-insurance pattern in...
