Child care and early education policies may not only raise average achievement but may also be of special benefit for less advantaged children, in particular if programs are high quality. We test whether high quality child care is equalizing using rich longitudinal data from two comparison countries, Denmark and the United States. In Denmark, we find that enrollment in high-quality formal care at age 3 is associated with higher cognitive scores at age 11. Moreover, the findings suggest stronger effects for the lowest-income children and for children at the bottom of the test score distribution. In the US case, results are different. We find that enrollment in school or center based care is associated with higher cognitive scores at school entry, but the beneficial effects erode by age 11, particularly for disadvantaged children. Thus, the US results do not point to larger and more lasting effects for disadvantaged children. This may be because low income children attend poorer quality care and subsequently attend lower quality schools.

This article describes trends in parental wealth homogamy among union cohorts formed between 1987 and 2013 in Denmark. Using high-quality register data on the wealth of parents during the year of partnering, we show that the correlation between partners’ levels of parental wealth is considerably lower compared with estimates from research on other countries. Nonetheless, parental wealth homogamy is high at the very top of the parental wealth distribution, and individuals from wealthy families are relatively unlikely to partner with individuals from families with low wealth. Parental wealth correlations among partners are higher when only parental assets rather than net wealth are examined, implying that the former might be a better measure for studying many social stratification processes. Most specifications indicate that homogamy increased in the 2000s relative to the 1990s, but trends can vary depending on methodological choices. The increasing levels of parental wealth homogamy raise concerns that over time, partnering behavior has become more consequential for wealth inequality between couples.

Economic transactions on online peer-to-peer platforms depend on buyers and sellers revealing personal information to facilitate exchanges with the unintended consequence that the information may become a source for discrimination. Using original panel data we show evidence of substantial discrimination against Arab/Muslim hosts in Airbnb’s online rental market in Paris, France. Analysis of 41-months of online transaction data shows a substantial increase in discrimination following large-scale, deadly terrorist attacks in November 2015. Discrimination results in a foregone monthly revenue of at least 106 US dollars for Arab/Muslim hosts in the year before the November 2015 attacks, after which losses increase to at least 178 US dollars. Our results demonstrate the association of mass terrorism with a contraction of a large-scale market of the sharing economy, the cost of which falls disproportionately upon members of an ethnic and religious minority.
