Changes to the Oil Export Structure of OPEC Member Countries — an Analysis with the Gini Coefficient

Abstract

This paper's goal is to analyse the impact of changes to the oil export structure on economic growth in OPEC Member Countries. The Gini coefficient has been applied simultaneously as a measure of the annual changes in the structure of per capita oil exports, as well as of the annual share of oil exports among Member Countries.The analysis consists of a calculation of the concentration coefficients, a determination of their trend and an identification of the factors most influencing observed changes to the oil export structure in these countries.As a result, we find that economic growth, crude oil production, proven reserves, imports and time are the major factors influencing changes to the oil export structure. Considering the changed structure, in the context of differences in oil export distribution, we observe that economic growth and production have a positive impact on the distribution of oil exports and that proven reserves and imports have a negative impact.December 1998

“…In the economic domain, the pioneering works referred to inequality in income distribution, but many of the methodologies developed for the analysis of this important question were later generalized to a multiplicity of phenomena, either in the economic domain, or in other areas of application [13]. Classical examples are the study of the distribution of wealth [6], production [4], health [1], education [29], of the largest or smallest concentration of clients in a company [17], etc.…”
