Recreating McKell Institute’s super-wages model

This repo attempts to recreate the McKell Institute’s super-wages model presented in their 2019 research paper ‘Does higher superannuation reduce workers’ wages?’.

It uses the statistical package R and publicly-available data. Three R scripts are used in order:

  1. 01_get_data.R: Retrive and tidy data from the ABS, OECD and RBA.
  2. 02_prepare_data.R: Combine data and generate variables for the model set.
  3. 03_run_regressions.R: Fit four models on each of AWOTE, AENA (wages) and AENA (social).

They compile relevant data and produce tables of regression results for four model specifications.

The results from these regressions are summarised in the charts below.

Model 1: Recreation of McKell models

Model 2: McKell model with pre-SG award

Model 3: McKell model with lagged SG one-quarter change

Model 4: The previous model with RBA specifications

You can’t perform that action at this time.
