Afternoon roundup

This afternoon's worthies on closing out the accumulated browser tabs:

• Russell Brown on cannabis reform, including links through to reasonable critiques of the Berenson work that's been floating around.


• Some excellent data work by Mike Reddell looking at the time path of employee compensation in NZ. Labour worries a lot about what they see as a declining labour share of income. Here are the key graphs.
  
  First up, employee compensation as fraction of GDP, adjusted for production taxes and subsidies. It's up on where it was in the 90s, but has been flat for the past decade.  
  
  
  
  Next up, wages as fraction of nominal GDP per hour worked:
  
  
  Reddell's summary:

  There is a fair bit of short-term noise, but the trend is pretty clear. On this data, wages have been rising faster than the overall earnings capacity of the economy. That was so in the 00s, and has been so – albeit to a lesser extent – in recent years too. For anyone inclined to want to debunk the analytical unadjusted series, note that this chart is not wildly inconsistent with the labour share chart I showed earlier: the labour share of total income has increased since the early 00s, with the biggest change occurring in the pre-recession 00s themselves.

  The underlying problem remains low productivity growth.


• Labour markets remain tight.


• These wonderful maniacs coded folklore from 1,000 pre-industrial societies to look for common traits that could be used in testing social science conjectures. Pastoral oral traditions have more motifs of anger and retaliation; foraging societies have more leisure-related motifs; political centralisation correlates with more use of trade and money words and with respect-related motifs. And old folklore predicts current views about things like toleration of socially deviant behaviour. Read! 


• Nudges are far less beneficial when we consider the psychological costs imposed on the nudgees. 


• Peer effects matter. Or, an argument against school zoning rules that concentrate disadvantage.


• Requiring a job search period before benefit uptake can be rather beneficial. It increases earnings and reemployment, without worsening health or crime outcomes.  


• Informal governance matters in disaster planning. I'm reminded of last year's Christchurch Earthquakes Symposium, where Hurunui District Council's Hamish Dobbie explained [my take on part of his talk] how their Council worked to enable civil society organisations rather than supplant them after the Kaikoura earthquakes. 


• And finally, Nate Silver:
