The JHR

For the full issue: jhr.uwpress.org/page/mortality

What determines life expectancy? From #ClimateChange to #income shocks, our latest #SpecialIssue expands on the growing research of previously misunderstood or understudied factors of longevity & the Determinants of Mortality. Remember to check it out! doi.org/10.3368/jhr.20…

In this #OpenAccess article, Anita Mukherjee & @nj_sanders find that intense unmitigated heat increases rates of severe violence among prisoners by 20% and the probability by 17%. A takeaway: heat mitigation doesn't just provide comfort, it saves lives. doi.org/10.3368/jhr.10…

Teach the #teacher? @POreopoulos, @chloergibbs, Michael Jensen & Joseph P. Price found that weekly coaching for teachers on computer assisted learning increased #student #math performance up to 0.22 SDs, especially when combined with consistent practice. doi.org/10.3368/jhr.12…

Current classroom standing and teacher perception. Max Coveney found that a primary #school #student's classroom rank affects #teachers' beliefs on their ability, regardless of their actual cognitive prowess. doi.org/10.3368/jhr.12…

Firms, family & child penalty. Elise Coudin, Sophie Maillard, Maxime Tô & Julie Tréguier found that mothers' incomes decline by 39% compared to fathers' post-childbirth. A solution: more #affordable #childcare & father involvement. doi.org/10.3368/jhr.04…

E-Commerce = #gender equalizer? Zengdong Cao, Wei Huang, Jinyang Ren & @Hantao_Wuu certainly suggest so. They found that #China's rural #ecommerce program increased female #labor participation by 4% and weekly work hours by 8%, along with other benefits. doi.org/10.3368/jhr.04…

#CPS interventions affect parents, especially mothers. Marie-Pascale Grimon found that, within a year following investigation, mothers are on average 5% and 11% more likely to use #MentalHealth and #SubstanceAbuse services, respectively. doi.org/10.3368/jhr.04…

Very glad to see this paper coming out soon in the JHR!

Female #students taught by same #gender professors in smaller classes are more likely to receive a top exam grade, but no such effect is found in larger classes. @maurer_se, Guido Schwerdt and @SimonWiederhold suggest why: Close interaction matters. doi.org/10.3368/jhr.02…

#Wealth, #fertility, & women's work. @celine_zipfel finds that in sub-Saharan Africa, these three are uniquely intertwined — and the data shows that expanding women's #wage opportunities could reshape family size norms. doi.org/10.3368/jhr.07…

Longer school days + better #resources = real gains. @taitarasu, @MartaFavara, Catherine Porter, & Alan Sánchez found that a Peruvian reform boosted #math scores by 0.19 SD & reading by 0.10 SD. Instructional time matters - but so do complementary inputs. doi.org/10.3368/jhr.11…

@danilaserra_eco 🙋‍♀️

Are economists #econtwitter still on here? Are new interesting papers and conference announcements still being posted? All I see is discussions on AI use for coding, and on how RCTs have ruined Development Econ research (again!) 🤷‍♀️ Anybody posting about actual research?🧐

Firms in Latin America & the Caribbean keep 45¢ of every $1 workers produce. Francesco Amodio, @bakonomics, @nico_de_roux, & @micdimaio found the fix. #Unions, #CollectiveBargaining & #unemployment protection — institutions that give money back to workers. doi.org/10.3368/jhr.09…

Pipeline programs work. Sarah R. Cohodes, Helen Ho, & Silvia C. Robles found that #underrepresented #minority high schoolers offered #STEM spots were more likely to graduate from elite colleges & earn STEM degrees — raising predicted earnings up to 15%. doi.org/10.3368/jhr.10…

Childhood exposure to #PoliticalViolence in Peru hurt #education — but only if you were in the womb. César A. Huaroto, Fredy Gonzales, & Alexander Pacheco found the original study missed key violations. #Replication matters. doi.org/10.3368/jhr.06…

#Welfare is more than just cash – it’s a de facto health safety net. Jeffrey Hicks’s new research shows #healthcare use spikes right before people apply for #benefits, suggesting they turn to welfare to survive temporary, work-limiting #HealthShocks. doi.org/10.3368/jhr.06…
