• Planet Money has a good episode analyzing an ISIS municipal budget, some interesting tidbits – ISIS fighters are paid in dollars, they like to buy Axe Body Spray, and ISIS issues looting permits.
• And if you like that, IPA’s Great Holiday Travel Podcast Playlist is here.
• Priceonomics has a fun story about how modern statistical hypothesis testing and sampling started with a Guinness brewer.
• The New Yorker on how we handle (or don’t) refugee mental health with the story of a former Sierra Leone child soldier trying to adjust to life in Minnesota.
• Paper: Using Bayesian hierarchical models to synthesize microcredit studies (PDF, via Rachel Glennerster).
• Yelp for Pakistani artificial insemination and many other interesting job market papers are on the Development Impact Blog.
• Reuters has an update from Burundi.
• There’s a big Guide To Bad Data from Quartz, including how to fix common formatting headaches, which numbers to be suspicious of, and why not to trust spreadsheets with 65,536 rows (the limit in older versions of Excel, which means that original data might have had more lines).
