In 1910, 12 percent of American 14-17 year olds were enrolled in high school; by 1930, enrollment had increased to 50 percent; enrollment in Britain was 12 percent in 1950. This paper argues that by increasing the skill premium, the massive inflows of European unskilled immigrants at the turn of...

The implication of increasing dependency ratios for pay-as-you-go, defined-benefit pension programs are examined. Modifications aimed at smoothing contributions while maintaining benefits intact are analyzed for both open and closed economies

This paper addresses the potential effects on human capital accumulation and economic growth of the alternative compositions of public expenditures in the context of a computable dynamic general equilibrium model of overlapping generations and heterogeneous agents in which altruistic parents...

This paper develops a public education scheme that takes uncertainty aspects of private educational investments explicitly into account. In the author’s framework, the social merits of public education schemes are related to the lack of markets in which students can insure against educational...

This paper presents a simple framework that illustrates the link between skill-based wage differentiation and human capital acquisition given skill-biased technical progress. The analysis points to the economic costs resulting from labor market and income redistribution policies that prevent the...

This paper uses a dynamic general equilibrium model calibrated to Ugandan data to examine the welfare effects of alternative scenarios of government expenditure and tax financing. Two expenditure types are considered: social spending that affects human capital, and infrastructure expenditures...

The present paper takes a fresh theoretical and empirical look into the relationship between Wagner’s law and economic development. It introduces human capital into a classic two-sector model of unbalanced growth. It shows that, as an economy develops, changes in the relative returns to human...

Population aging puts significant pressure on social security systems that are based mainly on a pay-as-you-go (PAYG) formula and determined by the political process in which both retirees and future retirees participate. This paper demonstrates that in an economic and demographic steady state,...

This paper examines the impact of social security on welfare. The provision of social security reduces precautionary savings and encourages early retirement. Consequently, it lowers aggregate capital, employment, output, and consumption. On the other hand, it also provides old age insurance....

Private transfers between individuals or through organized charities are increasingly viewed as an alternative for government social insurance programs. This paper models the incentive effects of government subsidized private transfers and finds that while there is a significant welfare benefit...
