Population aging is primarily the result of past declines in fertility, which produced a decades long period in which the ratio of dependents to working age adults was reduced. Rising old-age dependency in many countries represents the inevitable passing of this "demographic dividend." Societies...

Research on intergenerational transmission of wealth has pointed to uncertainty -- about the date of one's own death, for example -- as a potential source of significant bequest flows. In this paper I examine the effects of this same uncertainty on the behavior of those who expect to receive...

Census data from international sources covering 77% of the world's migrant population indicate that the skill composition of migrants in major destination countries, including the US, has been rising over the last 4 decades. Moreover, the population share of skilled migrants has been approaching...

The age-earnings profile of male workers is significantly influenced by the age composition of the workforce. When the number of young workers increased sharply in the 1970s, the profile "twisted" against them, apparently because younger and older male workers are imperfect substitutes in...

This note seeks the socioeconomic roots of racial disparities in COVID-19 mortality, using county-level mortality, economic, and demographic data from 3,140 counties. For all minorities, the minority's population share is strongly correlated with total COVID-19 deaths. For Hispanic/Latino and...

New York City is the hot spot of the COVID-19 pandemic in the United States. This paper merges information on the number of tests and the number of infections at the New York City zip code level with demographic and socioeconomic information from the decennial census and the American Community...

This paper develops a covariate-based approach to the external validity of instrumental variables (IV) estimates. Assuming that differences in observed complier characteristics are what make IV estimates differ from one another and from parameters like the effect of treatment on the treated, we...

The existing literature on the relationship between the share of elderly in a community and the support for local public education has led to mixed results to date. One potential reason behind this is that the share of elderly in a community is endogenous, and it is very difficult to disentangle...

This paper deals with the issue of using infant and childhood mortality as an indicator of inequality. The case is that of the United States in the 20th century. Using microdata from the 1900 and 1910 Integrated Public Use Microsamples (IPUMS), published data from the Birth Registration Area in...

Economists are often puzzled by the stronger public opposition to immigration than trade, since the two policies have similar effects on wages. Unlike trade, however, immigration can alter the composition of the local population, imposing potential externalities on natives. While previous...
