- “As a program adapts and serves more people and more functions, it naturally requires tighter regulation. Software systems govern how we interact as groups, and that makes them unavoidably bureaucratic in nature. There will always be those who want to maintain the system and those who want to push the system’s boundaries. Conservatives and liberals emerge.”
Here’s a useful thumb-rule. Read anything written by Atul Gawande. In this article, he speaks, nominally, about the difficulty of adapting to a new computer system that is being foisted upon the medical community. But there’s much more to unpack here! Adapting to systems, mutations within systems, the difficulty of scaling, substitutes and complements, opportunity costs – and much, much more.
- “Pig facial recognition works the same way as human facial recognition, the companies say. Scanners and software take in the bristles, the snout, the eyes and ears. The features are mapped. Pigs don’t all look alike when you know what to look for, they said.”
The intersection of technology, pork and the culture that is China today. Some might call this dystopian, others might fret at how slow progress is – but the article is fascinating.
- “The level of u* is not fixed. It changes over time, driven by changes in labor laws, the minimum wage, government benefit programs, demographics and technology. For instance, u* might decline if workers, on average, are older; older workers are less likely to be unemployed. The level of u* might rise if unemployment benefits become more generous and this leads unemployed workers to be more picky about taking jobs.”
NAIRU – or the Non-Accelerating Inflation Rate of Unemployment, was one of the more nerdy acronyms I learnt when I was a student. This article does a good job of explaining exactly what this is, and why it matters. And most importantly, it does so in a way that isn’t confusing for the layperson.
- “These calculations make clear why economists so often argue against light rail and subway construction projects. They are so expensive that ridership can only begin to cover construction and maintenance costs if the systems operate at close to their physical capacity most of the time; that is, if there are enough riders to fill up the cars when they run on two- to three-minute headways for many hours per day. Since most proposed projects do not meet this standard, economists generally argue against them. Buses can usually move the projected numbers of riders at a fraction of the cost.”
I am, and probably always will be, a huge fan of buses over other forms of public transport. And I will always be a big fan of public transport over private transport. This article explains why not just I, but other economists will also tend to favor buses over other forms of public transport.
- “The principle that you are presumed to be innocent unless and until you are convicted, after a fair trial, turns out, in practice, to be a different principle altogether: for the purposes of compensation, once you are convicted your conviction is deemed to be correct. You are presumed guilty for the rest of your life, irrespective of whether your trial was fair or unfair. It makes no difference that your conviction has been quashed. It makes no difference that new evidence – which ought to have been obtained by the police before your trial – shows that you are probably innocent. Those acting on behalf of the state may have bungled the investigation, and possibly even bent the rules to get you convicted. None of that is of any consequence. All that matters is whether you can prove that you suffered a “miscarriage of justice:” ”
I teach statistics, and would happily spend an entire semester explaining how to frame the null, and more importantly, hot to not frame the null. This article does an excellent job of providing an all too important example of the latter.
