This week in research #86

Here's what caught my eye in research over the past week:

• Street (with ungated earlier version here) finds that during the fracking boom in North Dakota, aggregate crime increased in fracking counties relative to non-fracking counties, but that local residents experience a modest decrease in criminal activity
• Nigai finds that exporting to more unequal countries increases domestic inequality, and that this might explain as much as 4.4 percent and 4.8 percent of the observed levels of Gini coefficients and income shares of the top 1 percent, respectively
• Harris and Mills (with ungated earlier version here) evaluate a randomized trial offering US ninth graders a $12,000 merit-based grant, and find that the program may have increased graduation from two-year colleges but did not affect overall college entry, graduation, employment, incarceration, or teen pregnancy
