Price indices and inflation

Price indices are used to assess how living standards have changed over time, to uprate state benefits and tax thresholds in line with increases in the cost of living, and to measure increases in house prices across regions of the UK.

Our research in this area looks at the advantages and limitations of different approaches to measuring price changes in various contexts. We also look at how households’ individual inflation experiences vary over time and across different demographic and income groups.

This paper uses revealed preference restrictions and nonparametric statistical methods to bound the true cost-of-living index which corresponds most closely to the UK Retail Prices Index (RPI)
