Economists have puzzled over why eligible individuals fail to enroll in social safety net programs. “Chilling effects” arising from an icy policy climate are a popular explanation for low program take-up rates among immigrants, but such effects are inherently hard to measure. This paper investigates a concrete determinant of chilling, Federal immigration enforcement, and finds robust evidence that heightened enforcement reduces Medicaid participation among children of non-citizens. This is the case even when children are themselves citizens and face no eligibility barriers to Medicaid enrollment. Immigrants from countries with more undocumented U.S. residents, those living in cities with a high fraction of other immigrants, and those with healthy children are most sensitive to enforcem...

American metropolitan areas have experienced rising residential segregation by income since 1970. One potential explanation for this change is growing income inequality. However, measures of residential sorting are typically mechanically related to the income distribution, making it difficult to identify the impact of inequality on residential choice. This paper presents a measure of residential segregation by income, the Centile Gap Index (CGI) which is based on income percentiles. Using the CGI, I find that a one standard deviation increase in income inequality raises residential segregation by income by 0.4-0.9 standard deviations. Inequality at the top of the distribution is associated with more segregation of the rich, while inequality at the bottom and declines in labor demand f...

In this paper we investigate the effect of relative income on marital status. We develop an identity model based on Akerlof and Kranton (2000) and apply it to the marriage decision. The empirical evidence is consistent with the idea that people are more likely to marry when their incomes approach a financial level associated with idealized norms of marriage. We hypothesize that the "marriage ideal" is determined by the median income in an individual's local reference group. After controlling flexibly for the absolute level of income and a number of other factors, the ratio between a man's income and the marriage ideal is a strong predictor of marital status -- but only if he is below the ideal. For white men, relative income considerations jointly drive co-residence, marriage, and fat...

Alcohol policies have potentially far-reaching impacts on risky sexual behavior, prenatal health behaviors, and subsequent outcomes for infants. We examine whether changes in minimum drinking age (MLDA) laws affect the likelihood of poor birth outcomes. Using data from the National Vital Statistics (NVS) for the years 1978-88, we find that a drinking age of 18 is associated with adverse outcomes among births to young mothers -- including higher incidences of low birth weight and premature birth, but not congenital malformations. The effects are largest among black women. We find suggestive evidence from both the NVS and the 1979 National Longitudinal Study of Youth (NLSY) that the MLDA laws alter the composition of births that occur. In states with lenient drinking laws, young black mo...
