InflacionVerdadera.com was created in 2007 to provide alternative price indexes to the official ones in Argentina. From 2007 to 2012 we published a Food and Drinks Index as well as a Basic Food Basket Index, using a combination of daily prices from two large supermarkets in Buenos Aires and the same methodologies of the INDEC before its intervention in 2007. Our task led us to create The Billion Prices Project at the Massachusetts Institute of Technology (MIT), y then PriceStats, the first private enterprise to calculate aggregate price indexes in the world.
In 2012 we summarized the results of our work with Argentina’s inflation statistics in this academic paper published in the Journal of Monetary Economics.
In August 2012, we replaced the original indexes of this site with a Consumer Price Index produced by PriceStats, an index that is comparable to the Aggregate CPI from the INDEC. The Index is published on a weekly basis by The Economist in replacement of INDEC’s official statistics. This new index accounts for additional categories of products and uses tens of thousands of daily prices obtained online from a great variety of retailers and sources throughout the country.
In all graphs the blue line corresponds to the official statistics (INDEC), and the orange line is the PriceStats’ index. All statistics are updated on a daily basis using data from 10-days ago. In order to retrieve the last available data point, place the mouse on top of the last point in the graph. The monthly inflation series in cvs (Excel compatible) can be downloaded in this site, doing click on “Argentina Daily Values (.csv download)” on the right menu.
