Retropolating some relevant series of Mexico's System of National Accounts at constant prices: The case of Mexico City's GDP

In Mexico, the System of National Accounts is disaggregated at the State level and expressed at constant prices of the most recent base year, 2008, for the years 2003 to 2015. Another frequently used database related to the National Accounts and disaggregated by State contains a quarterly index of economic activity. Further, a yearly database is also available with State‐level disaggregation and base year 1993, but it only covers the years 1993 to 2006 and employs a different classification system from that of base year 2008. In this work, we are concerned with the problem of retropolating the database of a Mexican State called Mexico City with the maximum level of disaggregation allowed by the publicly available databases. We followed a data‐driven approach and combined the three databases to produce an estimated homogeneous quarterly database with base year 2008, covering the years 1993 to 2015 and disaggregated up to groups of sectors.
