In person - joint Motu/Treasury Public Policy Seminar - NZ's discount rate

In 2024, the Treasury changed the discount rate they use to evaluate public sector proposals. The new discount rate for non-commercial proposals is 2% p.a. (real), while the rate for commercial proposals is 8%. The reduction in the discount rate for non-commercial proposals from 5% to 2% has important implications for proposals that enhance long-term social and environmental outcomes (and for other proposals with long-lived payoffs). Treasury has updated their cost-benefit analysis manual (CBAx) to include this (and other) changes. This seminar will discuss these discount rate changes.
One advisory input into the Treasury’s decision process was a commissioned expert paper by Motu Research’s Arthur Grimes,
This seminar is organised by Te Tai Ōhanga - The Treasury and Motu Research.
Speakers
Arthur Grimes (Motu Research) and Chris Parker (The Treasury New Zealand) will discuss ideas that led up to the changes.
Kirsten Jensen (The Treasury New Zealand) and Geoff Simmons (Parliamentary Commissioner for the Environment) will discuss the public policy relevance.
