The De La Salle University–Angelo King Institute for Economic and Business Studies (DLSU‑AKI) cordially invites the academic community and the general public to attend the DLSU‑AKI Paper Presentation entitled “Alternatives to CPI‑Based Inflation.” The paper will be presented by Neriza Chow* and Andrew Adrian Pua of the Carlos L. Tiu School of Economics, De La Salle University. The presentation will be held on 13 May 2026 (Wednesday), from 1:00 PM to 2:30 PM.

Abstract:
To supplement the Consumer Price Index (CPI) as a measure of inflation, we propose an alternative measure of inflation using implicit deflators derived from the national accounts (Gross Domestic Product (GDP), Household Final Consumption Expenditure (HFCE), and Total Supply (TS)). To make these measures timely, we estimate the monthly series of the quarterly national accounts using the temporal disaggregation method of Poissonnier (2017), from which we obtain the implicit deflators. We use Time-Varying Granger Causality (TVGC) tests to evaluate additional predictive content of these measures over CPI. Overall, we see a bi-directional relationship among the deflator-based inflation measures and CPI inflation. We observe that the TS deflator-based inflation measure demonstrates significant, unidirectional, and time-varying predictive content for CPI from 2022 to 2025. This suggests that the TS deflator captures external inflationary signals which are not immediately reflected in CPI inflation.
