This paper argues that the social nature of humans, absent from the standard economic model, is crucial to understand our large modern social states and why concerns about inequality are so pervasive. A social solution arises when a situation is resolved at the group level (rather than the...

A substantial literature addresses the design of transfer programs and policies, including the negative income tax, other means-tested transfers, the earned income tax credit, categorical assistance, and work inducements. This work is largely independent of that on the optimal nonlinear income...

European countries are much more generous to the poor relative to the US level of generosity. Economic models suggest that redistribution is a function of the variance and skewness of the pre-tax income distribution, the volatility of income (perhaps because of trade shocks), the social costs of...

In cross-sectional studies, countries with greater income inequality typically exhibit less support for government-led redistribution and greater acceptance of wage inequality (e.g., United States versus Western Europe). If individual nations evolve along this pattern, a vicious cycle could form...

This paper investigates the optimal income transfer problem at the low end of the income distribution. The government maximizes a social welfare function and faces the traditional equity-efficiency trade-off. The paper models labor supply behavioral responses along the intensive margin (hours or...

This paper uses earnings histories obtained from the Social Security Administration and linked to the survey responses for participants in the Health and Retirement Study to investigate redistribution under the current social security benefit formula. We find that as advertised, at the level of...

This paper examines the extent of redistribution that would occur under various annuity and bequest options as part of an individual accounts retirement program. I first estimate mortality differentials by gender, race, ethnicity and level of education using the National Longitudinal Mortality...

How much does the current social security system really redistribute from rich to poor? We use the PSID to estimate lifetime wage profiles and actual earnings each year for a sample of 1778 individuals, and we use mortality probabilities to calculate expected payroll taxes and social security...

This paper explores the role of government policies in a situation where the wage gap between high-skilled and low-skilled workers is widening due to increasing foreign competition in the manufacturing of low-skilled intensive goods. A two-period, two-sector general equilibrium model of a small...
