Nau mai hoki mai and hello again.

Since signalling an effective three-year wage freeze for most public servants a week ago, the government has been busy arguing the whole policy has been misinterpreted – right down to it not really being a wage “freeze” at all, but rather an attempt to prioritise those on the lowest incomes.

But is that really the case? As Canterbury University economist Laura Meriluoto writes, trying to help the less well off by capping the incomes of the better off is a strategy that could lead to all kinds of unintended consequences.

And, as Waikato University’s Al Gillespie so entertainingly argues, the law of unintended consequences was a lesson former prime minister and arch interventionist Robert Muldoon learned some decades ago.

There is plenty more to read in this newsletter and on our homepage, including an enlightening look at pop star Billie Eilish’s corseted cover shoot for Vogue, and the latest research into the likely impact of climate change on the planet’s already struggling coral reefs.

Thanks as always for your support and readership. Until next time, mā te wā and all the best.

Rachel Boddy, Te Herenga Waka — Victoria University of Wellington

Why now would be a good time for the Reserve Bank of New Zealand to publish stress test results for individual banks

Martien Lubberink, Te Herenga Waka — Victoria University of Wellington

New Zealand's financial system is sound but still vulnerable, according to the Reserve Bank. But without better evidence there's too much room for fear-mongering and confusion.
