The Labour Income Share in New Zealand: An Update
Earlier work by the New Zealand Productivity Commission investigated changes in the labour income share across the “former measured sector” part of the New Zealand economy between 1978 and 2010. This paper updates this earlier work by including additional data points for 2011-2016 and by increasing the scope of coverage to more industries in the economy. Focus is given to the decomposition of changes in the labour income share into growth in productivity and real wages. Findings are interpreted both within and outside an economic framework and are related to broad changes in technology and policy across the observed period.
