More On Poverty and Financial Literacy

Sendhil Mullainathan writes about the lessons the rich can learn from the poor about frugality for the Upshot.

Consider this situation: You’re shopping for headphones. An electronics store has the model you want for $50, a reasonable price. But a sales clerk says: “You know our other branch has this item on sale for $40.” Going to that store will take 30 minutes, and you can’t buy the headphones for that price online. Do you go to the other branch?

Before you answer, consider a slightly modified version of the same situation: Instead of headphones, you are buying speakers. You go to the same store and find the model you want for $400. Again, the price seems reasonable but the sales clerk says it’s on sale at the other branch for $385. What do you do now?

This is covering the same research as the earlier Wonkblog article.

Predicting Crime

Maurice Chammah, writing for The Marshall Project, writes about the St. Louis police departments’ use of crime-predicting software.

HunchLab, produced by Philadelphia-based startup Azavea, represents the newest iteration of predictive policing, a method of analyzing crime data and identifying patterns that may repeat into the future. HunchLab primarily surveys past crimes, but also digs into dozens of other factors like population density; census data; the locations of bars, churches, schools, and transportation hubs; schedules for home games — even moon phases. Some of the correlations it uncovers are obvious, like less crime on cold days. Others are more mysterious: rates of aggravated assault in Chicago have decreased on windier days, while cars in Philadelphia were stolen more often when parked near schools.

Promoting Your Research

Philip Cohen of Family Inequality has some suggestions for promoting your research:

These are some basic thoughts for academics promoting their research. You don’t have to be a full-time self-promoter to improve your reach and impact, but the options are daunting and I often hear people say they don’t have time to do things like run a Twitter account or write blogs. Even a relatively small effort, if well directed, can help a lot. Don’t let the perfect be the enemy of the good. It’s fine to do some things pretty well even if you can’t do everything to your ideal standard.

It’s all about making your research better — better quality, better impact. You want more people to read and appreciate your work, not just because you want fame and fortune, but because that’s what the work is for.

Changes in Incarceration Rates

Keith Humphreys, writing for WonkBlog, examines recent changes in the U.S. incarceration rates:

After decades of growth, the U.S. imprisonment rate has been declining for the past six years. Hidden within this welcome overall trend is a sizable and surprising racial disparity: African-Americans are benefitting from the national de-incarceration trend but whites are serving time at increasingly higher rates.

Historical Immigration to the U.S.

The University of Richmond Digital Scholarship Lab created an interactive map showing the foreign born population and countries of origin at the county level since 1850.

Marriage and Gender Equality

Philip Cohen of Family Inequality charts the correlation between marriage and gender inequality:

I used data from this U.N. report on marriage rates from 2008, restricted to those countries that had data from 2000 or later. To show marriage rates I used the percentage of women ages 30-34 that are currently married. This is thus a combination of marriage prevalence and marriage timing, which is something like the amount of marriage in the country. I got gender inequality from the U.N. Development Programme’s Human Development Report for 2015. The gender inequality index combines the maternal mortality ratio, the adolescent birth rate, the representation of women in the national parliament, the gender gap in secondary education, and the gender gap in labor market participation.
