Links for 13th March, 2019

  1. “For most projects I’ll never look at anything in ARCHIVES again. But of course it’s easy to do so if I want to. And the fact that it’s easy is important, because it means I don’t have nagging concerns about saying “this is finished with; let’s put it in ARCHIVES”, even if I think there’s some chance it might become active again.As it happens, this approach is somewhat inspired by something I saw done with physical documents. When I was consulting at Bell Labs in the early 1980s I saw that a friend of mine had two garbage cans in his office. When I asked him why, he explained that one was for genuine garbage and the other was a buffer into which he would throw documents that he thought he’d probably never want again. He’d let the buffer garbage can fill up, and once it was full, he’d throw away the lower documents in it, since from the fact that he hadn’t fished them out, he figured he’d probably never miss them if they were thrown away permanently.”
    It is exhausting just reading it, but a very long article from Stephen Wolfram o how he organizes his life. You don’t have to go quite as all out – but you might learn a trick or two about organizing your life better by reading this article. God knows I need all the help I can get.
  2. “Nonetheless, this work suggests a potentially serious problem. Many situations in economics are complicated and competitive. This raises the possibility that many important theories in economics may be wrong: If the key behavioral assumption of equilibrium is wrong, then the predictions of the model are likely wrong too. In this case new approaches are required that explicitly simulate the behavior of the players and take into account the fact that real people are not good at solving complicated problems.”
    If I was to be (excessively?) cynical, I’d say this would mean that economists know nothing. But that isn’t necessarily true – Herbert Simon’s work on bounded rationality come to mind here. But the article is interesting about how to think about excessively complicated stuff – such as life.
  3. “In a low-saving, low-investment economy like the US, it’s a little hard to conceive that its possible for savings and investment rates to be too high for a country’s economic health. But that’s where China has been, and shifting away from established patterns is rarely simple.”
    To range across domains, there is this line from dietary studies that goes something like this: “It is the dose that makes the poison”. But if the USA suffers from too low a savings rate (maybe), China has the opposite problem. And this article does a great job of explaining the how and the why.
  4. “Historically, interim budgets in India have consistently overestimated revenue growth and underestimated expenditure growth. An analysis of the projected, revised, and actual budget figures since 1991 by Deepa Vaidya and K. Kangasabapathy of the EPW Research Foundation showed that deviations from budget estimates tend to be extraordinarily high for budget estimates presented in interim budgets ”
    This should surprise nobody, but budgets shouldn’t be trusted. Households budgets tend to have the same biases and errors that government budgets do, and for mostly the same reason – they’re drawn up by humans, who will be tempted to gloss over inconveniences. This article is full of interesting infographics that help you understand this point better – and also makes the point that an independent fiscal council is both necessary and overdue. I wouldn’t hold my breath.
  5. “But as the global giants arrive, they have been driving up salaries, rents, and reputations. Now some fear that the multinationals that once nurtured this fledgling technology powerhouse are unwittingly damaging the potent but fragile mix of entrepreneurship, military training, and chutzpah that drew them to it in the first place. That, they worry, could prevent it from developing into a mature digital economy.”
    Can you guess, before you click on the link, which country we’re talking about? Reading this article should make you want to read more about industrial organization, low interest rate environments, and urbanization – three of the biggest issues in economics today.
