Examining the college premium
Higher education is widely understood to be a major driver of intergenerational mobility in the United States. Despite the clear (and growing) inequalities between and within colleges, it remains the case that higher education reduces the impact that parental class position has on a graduate's life outcomes.
In an intriguing paper, associate professor of economics at Harvard XIANG ZHOU scrutinizes the implied causal relationship between college completion and intergenerational mobility. Specifically, Zhou uses a novel weighting method "to directly examine whether and to what extent a college degree moderates the influence of parental income" outside of selection effects, seeking to distinguish between the "equalization" and "selection" hypotheses of higher ed's impact on intergenerational mobility.
From the paper:
"Three decades have passed since Hout’s (1988) discovery that intergenerational mobility is higher among college graduates than among people with lower levels of education. In light of this finding, many researchers have portrayed a college degree as 'the great equalizer' that levels the playing field, and hypothesized that an expansion in postsecondary education could promote mobility because more people would benefit from the high mobility experienced by college graduates. Yet this line of reasoning rests on the implicit assumption that the 'college premium' in intergenerational mobility reflects a genuine 'meritocratic' effect of postsecondary education, an assumption that has rarely, if ever, been rigorously tested.
In fact, to the extent that college graduates from low and moderate-income families are more selected on such individual attributes as ability and motivation than those from high-income families, the high mobility observed among bachelor’s degree holders may simply reflect varying degrees of selectivity of college graduates from different family backgrounds."
In sum, Zhou finds that the "selection" hypothesis carries more weight than the "equalization" hypothesis. One implication of this finding is that "simply expanding the pool of college graduates is unlikely to boost intergenerational income mobility in the US." Link to the paper.

But in the context of public investment in higher education, we need to know not only how individuals are faring but also how investments in higher education are affecting our workforce and the economy as a whole."

How childcare impacts women's participation in the labor market
University of Rochester PhD candidate and soon to be assistant professor of economics at Temple University VIVIANE SANFELICE studies development economics with a focus on the public sector. In a 2018 working paper, she examines the effect of childcare accessibility on women’s labor force participation rates by comparing outcomes for mothers of children from different age groups in Brazil.
From the abstract:
"My findings show that the availability of formal childcare allows mothers to join the job market. Among women sensitive to the availability of free care, three fourths of their employment rate is explained by whether or not they obtain a public slot. This matches the dominant finding of the literature to date: maternal employment is most responsive to childcare expansion in contexts where either it or alternative childcare providers are low prior to the intervention."

As low and middle income families pay back their debts, we not only see declining living standards, but we also see the opening for another recession." An interview with Steven Pressman. Link.

We exploit two natural experiments in English history, resulting in sharp decreases in punishment severity: the offense-specific abolition of capital punishment and the temporary halt of penal transportation during the American Revolution. Using difference-in-differences to study the former and a pre-post design for the latter, we find a large, significant, and permanent impact on jury behavior: juries are more likely to convict overall and across crime categories. Moreover, the effect size differs with defendants' gender." By Anna Bindler and Randi Hjalmarsson. Link. ht Jennifer Doleac.
