IHACPA NEP/NWAU notes (terminology discipline)

Date: 21 December 2025

The National Efficient Price (NEP) is published annually by IHACPA as a dollar value per NWAU (National Weighted Activity Unit). In activity-based funding (ABF), an individual episode’s payment is typically computed as:

Payment = NWAU (case-mix weight × adjustments) × NEP (annual $/NWAU) × jurisdictional arrangements

This repository treats “valuation pressure” as a stylised concept capturing how differences between input-cost growth and efficient-price indexation can create an “efficiency gap” that matters for behaviour at the Commonwealth–State interface. The model does not attempt to reproduce the full NWAU calculators or every ABF adjustment.
