One of the variables with the greatest impact on consumption decisions are prices, which fell on aggregate by 0.3% in 2020 in Spain according to official data.25 However, there were marked changes in consumption patterns last year, making it very difficult to accurately measure the figure actually faced by consumers. CaixaBank’s own estimates based on high-frequency internal data suggest that inflation was somewhat higher, namely 0.1%.26 Moreover, inflation did not affect everyone equally, with differences depending on age and income.
- 25We have analysed inflation using the Harmonised Index of Consumer Prices (HICP) produced by the National Statistics Institute.
- 26Other studies also using high-frequency data have found a difference with respect to the official inflation data between April and December 2020 of 0.06 pp, 0.30 pp and 0.58 pp for the United Kingdom, Canada and United States, respectively, and between April and September of 0.60 pp for France (in our study for Spain, the estimated difference for both periods is 0.58 pp and 0.67 pp, respectively).
