Using IDI Data to Estimate Fiscal Impacts of Better Social Sector Performance

Published 22 Nov 2016

Author: Robert Templeton

Abstract

The analysis was undertaken as part of the work to update Treasury’s long term fiscal modelling.  As part of this a scenario analysis of the potential fiscal and non-fiscal benefits of social investment was undertaken and is described in ‘The benefits of improved social sector performance’, a detailed background paper to He Tirohanga Mokopuna, the Treasury’s long-term fiscal statement (LTFS).

The paper provides information about how we used data from SNZ’s Integrated Data infrastructure (IDI) to inform the scenario analysis.

The paper also provides a  descriptive picture of potential non-fiscal outcomes relating to the same scenarios.  The results of this work have been incorporated into He Tirohanga Mokopuna and the background papers but this report is being made available for those interested in more of the details behind some of the scenario analysis.
