Accounting dollarization compared to Brazilian-style indexation

Brazil indexed all non-monetary items during the 30 years from 1964 to 1994 by means of a daily non-monetary index supplied by the various governments over that period for everybody in the economy to use daily. Although the Brazilian indexes used during those 30 years were almost entirely based on the daily US Dollar exchange rate with the Brazilian currency, it was not a parallel rate used parallel to another “official” US Dollar exchange rate arbitrarily set by the government as happens in most cases where a parallel market for the US Dollar develops in hyperinflationary economies. However, the daily index supplied by the government was not the actual daily US Dollar exchange rate. Thus, although the Brazilian indexation was financial capital maintenance in units of constant purchasing power during those 30 years, and very similar to accounting dollarization, it was not exactly the same.

Brazilian indexation theoretically maintained the constant item economy perfectly stable whereas there is still real value erosion in the constant item economy as a result of the stable measuring unit assumption at a rate equal to the inflation rate in the US Dollar when accounting dollarization is employed. Brazilian-style indexation is thus better than accounting dollarization since real value erosion because of the use of the stable measuring unit assumption is completely eliminated with financial capital maintenance in units of constant purchasing power in terms of the daily index rate.
