Abstract

Decision is offered to each of the three main aspects of comparison: a simple commodity conformity has been achieved for the period 1986 - 2006 on the grounds of the turnover sector structure according to the Industrial Classification System'86 and the New Customs Tariff'92. The turnover was evaluated in USD for the period 1986 - 1990 based on import and export values in USD for 1991, published by the Bulgarian National Statistics Institute and the reported indexes of their volumes according to comparable prices between 1986- 1991. Deflators are introduced based on the average annual inflation rate of the industrial country (as per IMF classification) to correct the annual indexes of the value scopes of turnover after 1991, supplementing the comparison in the monitored period.
