Accurately measuring inflation is essential for implementing monetary policy aimed at maintaining price stability. Key challenges include accounting for changes in product quality, capturing price dynamics in the digital economy, and analyzing how inflation may differ between various consumer groups who face distinct consumption baskets—especially in periods of heightened inflation. Beyond accurate measurement, a deeper understanding of inflation dynamics is equally important. While conventional determinants—such as oil prices and domestic demand—remain relevant, emerging factors like climate shocks (e.g., extreme weather events) may also influence inflation. The effects of such shocks on Thai inflation are not yet well understood.

1. Inflation measurement and quality adjustment in key sectors, e.g., automobiles, housing, healthcare.
2. Price-setting behavior and inflation measurement using survey and/or online price data.
3. Alternative inflation indices for different consumer classes (e.g., rich vs. poor).
4. Inflation drivers – how traditional drivers and new factors affect inflation and what are their implications for monetary policy?

1. Micro-level online price data set from Thai supermarkets (2020–2025)
2. Historical data on temperature, precipitation, and climate indices such as SPI and SPEI from 1970 to 2022, along with future climate projections for Thailand from 2040 to 2099 at district and provincial levels.
