Most expansion files are determined from weighted midpoints of chosen cost changes. This essentially presents twisting, and can prompt genuine questions about what the genuine expansion rate is. This issue can be overwhelmed by including all suitable cost changes in the estimation, and afterward picking the middle value.[46] In a few different cases, states may deliberately report bogus expansion rates; for example, during the administration of Cristina Kirchner (2007-2015) the public authority of Argentina was condemned for controlling monetary information, for example, expansion and GDP figures, for political increase and to decrease installments on its expansion recorded debt.
