  1. “The researchers discovered that commonly visited places, like coffee shops, can be within a few feet of each other but they can each primarily have visitors from completely different income brackets. This indicates that economic inequality isn’t just present at the neighborhood level, but it can also show up among the places people visit as part of their daily routines. It suggests that income inequality might impact not just where people live, but also where they go. ”
    A great article to help you think through the following: inequality, how to measure it, how to measure it using modern methods, what is the difference between class inequality and income inequality, sampling, the limitations of sampling, the Data For Good initiative, 100 Resilient Cities and the SmartCitiesDive program.
  2. “An experiment that the researchers arranged hinted at a possible explanation of the correlation they found. They asked participants to picture and describe what it would be like to have a certain amount of daily free time, and then report how they’d feel about that allotment. “What we find is that having too little time makes people feel stressed, and maybe that’s obvious,” says Holmes. “But interestingly, that effect goes away—the role of stress goes away—once you approach the optimal point.” After that point, Holmes says, the subjects started to say they felt less productive overall, which could explain why having a lot of free time can feel like having too much free time.”
    One of my favorite Calvin and Hobbes strips has the quote “there never is enough time to do all the nothing you want to”, or words to that effect. This article tells you that having more than 2.5 hours of “nothing” time may well be too much.
  3. “While India has 70-odd companies that are rated highest quality, only two companies in the US enjoy this distinction. No company in Germany and UK enjoys AAA rating. Among emerging countries, China has only 14 AAA-rated entities. This implies a gulf between credit standards in India and elsewhere. The exacting standards observed in other countries are missing among domestic agencies.”
    Via Gulzar Natarajan, this article points out a disturbing statistic – Indian firms might well be given ratings that don’t really indicate their reliability. Rating agencies the world over took a hit to their reputation post the 2008 crisis, but this story seems to be unique to India. The article does have some caveats, but I’d say the news is, even so, worrying.
  4. “We employ Comin et al.’s (2010) data on ancient and early modern levels of technology adoption in a spatial econometric analysis. Historical levels of technology adoption in a (present-day) country are related to its lagged level as well as those of its neighbors. We allow the spatial effects to differ depending on whether they diffuse East-West or North-South. Consistent with the continental orientation hypothesis, East-West spatial effects are generally positive and stronger than those running North-South.”
    Are you familiar with vertical vs horizontal business models? Apple is vertical (controls everything, end-to-end) and Netflix is horizontal (needs to be available across multiple verticals to succeed). I was strongly reminded of that when I read this.
  5. “He is maddening in ways they never anticipated, along vectors they’ve never seen; he is a tireless innovator in the craft of mass irritation. He can cause fans to go absolutely nuts whether he wins or loses. McEnroe himself has spent a good chunk of the past five years complaining about Kyrgios, and McEnroe is probably the greatest tennis player of all time at driving people wild. Being found intensely annoying by John McEnroe is a high honor for any exasperating person. It’s like Beethoven humming your melody.”
    In which Brian Philips makes the case for the upside to Kyrgios being, well, Kyrgios. The interesting question is where else might such a contrarian philosophy work, and why?
