Sometime back Paul Graham wrote about a way to detect bias, namely by measuring the relative ability of people who are selected. I.e., if women are discriminated against, they should outperform men. I did a little more math on that topic. Now Jonathan Adler is using this idea to investigate whether conservative law professors are discriminated against. Apparently conservative law professors are significantly more productive than their liberal counterparts, suggesting that there may be possible discrimination.

Systems, not Sith: How Inter-service Rivalries Doomed the Galactic Empire

Hedonic Adjustments over long periods of time. This article argues a point I've long held, that inflation is non-transitive. I.e., the rate of inflation from 1970->2016 is not equal to inflation 1970->1990 + 1990->2016. The reason for this is ultimately changes in the basket of goods - changing the basket of goods gets you a very good inflation rate in any given year, but a completely nonsensical one over time.

Nice introductory article on covariance/contravariance.

Why Costs Matter - an article explaining why transit activists need to focus on out of control construction costs.
