The argumentation is solid, built on a transparent methodology and robust data sources. The speaker clearly explains the construction of the indices and demonstrates their utility through empirical analysis. She acknowledges limitations, such as the assumption about non-housing goods and the use of rental prices for homeowners, and engages with audience questions, strengthening the credibility of the work.
Scientific Rigor, Source Quality, Title Accuracy
The scientific rigor is evident in the use of official data sources and the careful handling of data limitations. The speaker cites relevant literature, such as work by Moretti and Diamond, and provides a detailed account of the data and methodology. The title accurately reflects the content, focusing on local cost of living and inequality in Spain. The presentation is well-structured and the speaker’s expertise is clear.

Contribution & Novelties
The main contribution is the creation of a new public database of local consumer price indices for Spain, disaggregated by municipality and income group, covering 2006-2022. This allows for more accurate measurement of inequality and poverty by accounting for spatial price differences. The research demonstrates that national inflation adjustments can misrepresent trends, with significant policy implications.
Pour aller plus loin :
- Consumer price index — Provides background on CPI methodology.
- Gini coefficient — Commonly used measure of income inequality.
- Oxford Poverty and Human Development Initiative — The speaker’s institution, relevant for poverty research.
