  1. “What is not useful is the sense that measuring GDP is the problem, and measuring gross national happiness is the solution. Few societies have ever really focused on either. We should all be happy about that.”
    Tim Harford reminds us that the truth lies somewhere in the middle. In this case, the article is worth reading for understanding how GDP can’t really be measured, and how that may not be a bad thing. In addition, please read the article to understand that Bhutan probably isn’t all that “happy” a country in the first place!

  2. “Given the pressure on all unions to negotiate higher-than-average wage increases, using monetary policy to reduce inflation would inevitably aggregate spending to fall short of the level needed to secure full employment, but without substantially moderating the rate of increase in wages and prices. As long as the unions were driven to negotiate increasing rates of wage increase for their members, increasing rates of wage inflation could be accommodated only by ever-increasing growth rates in the economy or by progressive declines in the profit share of business. But without accelerating real economic growth or a declining profit share, union demands for accelerating wage increases could be accommodated only by accelerating inflation and corresponding increases in total spending.”
    Monetary nerds only, it should go without saying! David Glasner runs a blog called Uneasy Money, which is well worth reading, but only if you want to find yourself steeped in all things monetary. This post takes a slightly critical view of Arthur Burns tenure as Fed Chairman.

  3. “Amazon’s economists game out real estate decisions, set the lowest prices that will deliver a profit, precisely determine what customers care about and whether advertisements are working — all using machine-learning algorithms that automate decision making on a massive scale. It’s the kind of asset that smaller companies can’t always pay for, allowing Amazon to pull further and further away from the competition.”
    Amazon has, in case you didn’t know, probably the world’s largest collection of PhD’s in economics. This article helps you understand what it is that they do once they’re in Amazon. A helpful read if you are considering building a career in economics.

  4. “The White House explains why it’s predicting such big growth: the TCJA will cause a surge in business investment by “substantially raising the target capital stock and attracting increased net capital inflows.” And this rise in the capital stock will cause a surge in productivity. Except that there’s no sign of a surge in business investment: the report cherry-picks a few numbers, but overall orders for capital goods, probably the best real-time indicator, are showing nothing much (that 2015-6 slump, by the way, was about fracking, which fell off for a while when world oil prices plunged)”
    Paul Krugman is less than impressed with the 2019 Economic Report of the President, and provides data to show why he is less than impressed. The chart that follows the excerpt is worth looking at too.

  5. “There’s one biosignature that Seager, Guyon, and just about everyone else agree would be as near a slam dunk for life as scientific caution allows. We already have a planet to prove it. On Earth, plants and certain bacteria produce oxygen as a by-product of photosynthesis. Oxygen is a flagrantly promiscuous molecule—it’ll react and bond with just about everything on a planet’s surface. So if we can find evidence of it accumulating in an atmosphere, it will raise some eyebrows. Even more telling would be a biosignature composed of oxygen and other compounds related to life on Earth. Most convincing of all would be to find oxygen along with methane, because those two gases from living organisms destroy each other. Finding them both would mean there must be constant replenishment.”
    That’s just one of many, many excerpt-able pieces from a very long, but also very rewarding article about the search for ET. Take your time with this one – about an hour or so, and pay particular attention to the infographics.
