Weekend roundup

A few of the worthies on a closing of the browser tabs.

• American schools might start letting the kids have access to sunblock. HT: RoyalAlbertRoss in comments, here.
• Henry Cooke goes the consequences of New Zealand's dumb panic over meth-contaminated houses. 
• John McCrone covers the merits of allowing urban expansion around Christchurch. The towns around Christchurch are booming. 
• I'm sure there are lots of different economics blog rankings around, but this one counts Offsetting Behaviour in the top 100. As it did last year and the year before as well. 
• Treasury has the 2018 version of its essay contest up for those tertiary students so-inclined. Whether it reinforces or mitigates the bad separating equilibrium they've had going on over there I suppose is an empirical question.
