Competition and productivity
Recent research by Motu Economic and Public Policy (Maré & Fabling, 2019a) highlights different aspects of competition within industries in New Zealand. This work draws on a redeveloped firm-level productivity dataset (Maré & Fabling, 2019b) and forms the basis for a summary report and web-based data visualisation tool (competition explorer) (Schiff & Singh, 2019). (The data files for this tool are available in the downloads section above.)
This research was funded by the Ministry of Business, Innovation and Employment, New Zealand Productivity Commission, and The Treasury, with the Commerce Commission and Stats NZ providing advice on the project. A Cut to the Chase explains why these agencies undertook this work and some of the key messages that emerged.

Access to the anonymised data used in this study was provided by Stats NZ under the security and confidentiality provisions of the Statistics Act 1975.

Careful consideration has been given to the privacy, security, and confidentiality issues associated with using administrative and survey data in the IDI.
