Yet another study debunks the ocean acidification scare Further evidence that ocean acidification is a non-event, scientifically, even while being a big event for scientists financially: Thus, both of the investigated coastal plankton communities were unaffected by twenty-first century expected changes in pH and free CO2. This may be explained by the large seasonal, and […]

How to regulate the psychology of regulators My latest column in the Wall Street Journal is about the psychology of bureaucracy. just as we need to understand the human proclivities that give rise to booms and busts in markets, so we need to understand the human proclivities that motivate officials. Here are five identified by Slavisa […]

Plus other matters aired on the radio Here’s an hour long conversation I did on Econtalk with economist and novelist Russ Roberts about trade, prosperity and Adam Smith. It includes a discussion of why animals can manage reciprocity but not, apparently, exchange.

The first, by Brendan O’Neill, in Spiked (hat tip: Frank Stott), reveals the degree to which the miners helped themselves to cope […]

Or rather, why did it not peter out? At Cato Unbound, there is a set of essays on the subject in response to Deirdre McCloskey, one of which is by me, others by Greg Clark and Jonathan Feinstein. I champion the theory that coal was crucial, because it showed increasing rather than diminshing returns (the more people […]

My latest Mind and Matter column in the Wall Street Journal On the failed promise of genomics. Is it because common ailments are caused by many different rare genetic variants?

GM crops benefit non-GM crops nearby Do you remember how, back in the days when genetically modified crops were as vilifed as climate sceptics were until recently, one of the arguments deployed against them was that they would `contaminate’ neighbouring farms with their genetically modified pollen? This was one justification for a total ban, as […]
