A Contribution Towards New Zealand’s Tax Reform


  • Laabas, Belkacem
  • Razzak, Weshah


We use the work-leisure choice model to estimate equilibrium labour supply (hours-worked) in New Zealand over the period 2000 – 2008. We then stochastically solve the model over a future period from 2010 to 2050, and evaluate the New Zealand’s new tax policy. We compare the welfare and relative productivity (i.e., relative to Australia) outcomes for several tax policy scenarios.
