“…Price changes are weighted using Argentina's National Statistics Office (INDEC) official weights by CPI category. (See Cavallo, 2013, andBertolotto, 2020, for evidence that online price indices closely track and forecast official CPIs. )…”

“…The Billion Prices Project's academic output, which is nicely summarized in Cavallo and Rigobon (2016), informs many of our modelling decisions and inferences. Aparicio and Bertolotto (2016) have presented CPI forecasts informed by web-scraped prices, as computed with a low order auto-regressive moving average model with exogenous inputs. The exogenous variable here is an aggregated CPI computed from web-scraped prices.…”

“…Hendry and Hubrich (2011) show that adding disaggregated sector-level information into forecast models improves forecast accuracy for aggregate US inflation. Aparicio and Bertolotto (2020) use combinations of high-frequency online price item series to forecast CPI one to three months ahead in ten advanced economies; their forecasts outperform benchmark models as well as surveys of forecasters by anticipating changes in official inflation rates. Closest related to our approach, Ibarra ( 2012) uses a factor model based on 243 CPI item series and 54 macroeconomic series to forecast aggregate CPI in Mexico, reaching a forecasting performance comparable to forecasts from expert surveys.…”
