Recent papers on state sector productivity

Public sector productivity: Quality adjusting sector-level data on New Zealand schools

This working paper looks at a range of quality adjusted productivity measures and discusses the benefits and risk of different approaches. It includes one series that benchmarks the results in the study with similar work in the UK (by the Office for National Statistics). The focus on the education sector is consistent with the Better Public Services programme and the overall intent to upskill the economy.

Social sector productivity: a task perspective

This research note explores how the scope for productivity measures in the public sector can vary depending on the nature of the task. While the paper focuses on the social sector, the idea of distinguishing between different types of tasks could potentially be useful for other sectors. It was prepared by a MPP student for the internship component of her degree over summer 2016-17.

Both papers will be useful information for the Commission's inquiry into State sector productivity.

Explaining ethnic disparties in bachelor's qualifications: participation, retention and completion

The Productivity Commission and Auckland University of Technology (AUT) have published joint research that looks at the factors associated with undertaking bachelor’s degree study in New Zealand.

The research is a detailed, comparative analysis of the factors that contribute to ethnic disparities in bachelor’s qualifications in New Zealand. 

Achieving New Zealand's productivity potential

The Productivity Commission has just released a paper about why New Zealand has generally struggled to lift productivity over the last four decades and the broad areas of policy reform that would help in turning that around.

Written by Paul Conway, Achieving New Zealand's productivity potential presents a detailed analysis of the issues.

Productivity Hub

We work with other government agencies through the Productivity Hub, which we convene and chair. The Hub plays a coordination role which helps inform the research choices of each participating agency, and advance collaborative research projects. The Hub also engages with a wider research community outside government.


The Commission has requested independent evaluations of our research function.

Paul is an economist with extensive international experience and has previously worked with the OECD, the World Bank, Westpac and the Reserve Bank of New Zealand. His work has included published studies on the impact of regulation on competition and productivity in New Zealand, China, Russia and India, as well as broader OECD-wide analysis.
