Seth Stephens-Davidowitz in The New York Times:
We now know who is rich in America. And it’s not who you might have guessed. A groundbreaking 2019 study by four economists, “Capitalists in the Twenty-First Century,” analyzed de-identified data of the complete universe of American taxpayers to determine who dominated the top 0.1 percent of earners. The study didn’t tell us about the small number of well-known tech and shopping billionaires but instead about the more than 140,000 Americans who earn more than $1.58 million per year. The researchers found that the typical rich American is, in their words, the owner of a “regional business,” such as an “auto dealer” or a “beverage distributor.”
…The most important happiness study, in my opinion, is the Mappiness project, founded by the British economists Susana Mourato and George MacKerron. The researchers pinged tens of thousands of people on their smartphones and asked them simple questions: Who are they with? What are they doing? How happy are they? From this, they built a sample of more than three million data points, orders of magnitude more than previous studies on happiness. So what do three million happiness data points tell us?
