This paper considers an economy where individuals differ in productivity and in risk. Rochet (1991) has shown that when private insurance markets offer full coverage at fair rates, social insurance is desirable if and only if risk and productivity are negatively correlated. This condition is...

Rothschild and Stiglitz (1976) show that there need not exist a competitive equilibrium in markets with adverse selection. Building on their framework we demonstrate that externalities between agents - an agent's utility upon accepting a contract depends on the average type attracted by the...

We characterize how public insurance schemes are constrained by hidden financial transactions. When non-exclusive private insurance entails increasing unit transaction costs, public transfers are only partly offset by hidden private transactions, and can influence consumption allocation.

Unemployment Insurance Savings Accounts (UISAs) entitle workers to unemployment benefits at the expense of future pension payments. Therefore, such accounts make unemployment less attractive, intensify job search, and raise employment. In the present paper the wage and employment consequences of...

When social security is established to provide pensions to parents, their reliance upon children for future financial support decreases; and their need to save for retirement also falls. We use the expansion of pension coverage from the state sector to the non-state sector in urban China as a...
