So our Joel Hernandez has completed some more work on what’s all going on in New Zealand’s school system and an Auckland Uni education prof is mad about it. Oh well. Joel’s long term project has been to look at differences in outcomes across students and schools, using the administrative data held in the StatsNZ data lab … Read More

There is much to be despondent about looking ahead to the consequences of a changing climate. But adopting Jonathan Franzen’s defeatism isn’t the best response. Reducing adverse impacts of climate change isn’t as simple as regulating automotive emissions, banning a pesticide of refrigerant, or changing to LED lights. But nor is it as … Read More

Two centuries ago there was an allegory doing the rounds of England. A “New Zealander” – meaning a Māori – at some latter date sat drawing the ruins of London. A sign that all great cities and civilisations eventually diminish and others take their place. Detail from Gustave Doré. “The New Zealander” in London: … Read More

James Shaw, co-leader of the Green Party and Minister for Climate Change (surely Minister against it?), tells us he is working his way through 15000 submissions on the recent climate change consultation document. I’ve done a couple of posts here on the document, and on the NZIER modelling used extensively in it, and I’ve chided both the Minister … Read More

By Matt Boyd and Nick Wilson We have just published an article (free online) on existential risks – with an NZ orientated perspective.1 In this blog we discuss some of the issues that NZ society could start to discuss. Do we value future people? Do we care about the wellbeing of people who don’t yet exist? Do we care … Read More

We’ve known about the problems of publication bias at least since 1992. If it’s easier to get statistically significant results published than insignificant results, then there are whole literatures that become untrustworthy. Andrea Menclova at Canterbury is doing something about it. This has been a while in the making – we were talking about it when I was still at … Read More

You want to buy a widget. Bugsy’s has the model you want, it’s $6. Malone’s also sells it, for $5. You may not know Malone’s got it cheaper, so you end up paying a dollar too much at Bugsy’s. But suppose Bugsy’s and Malone’s are required by the Prevent-A-Widget-Ripoff Authority to post their prices online? With a moment’s search you … Read More

Lots of people, even abroad, look at New Zealand’s economy. For example, there are ratings agencies selling a commercial product to clients, and there are investment funds putting their own and clients’ money at risk. And then there are the government agencies; notably the IMF and the OECD. Every year or so, a small team of IMF … Read More

Looks like folks are back to arguing about whether there’s a J-curve in alcohol consumption. The J-curve plots out the relationship between all-cause mortality and drinking. Non-drinkers are at the left-hand upwards tip of the J, light-to-moderate drinkers are in the dip, then heavy drinkers are in the upwards tilt at the right hand side. And the ballpark numbers I … Read More

There have been a few posts here (here, here, and here) in the last week or so around the issue of population size and GDP per capita – not because my prior is that there is any such relationship but (a) because I think there isn’t, and it is worth occasionally illustrating that across countries, and (b) … Read More
