Measurement and analysis of superior efficiency: An applied study on a sample of companies listed in the Iraqi Stock Exchange for the period 2016-2020
Main Article Content
Abstract
The research aimed to measure and analyze the super efficiency of a sample of companies listed in the Iraq Stock Exchange, as the variables of the super-efficiency model included inputs and outputs, as they included inputs (total costs X1, paid-up capital X2, debt ratio X3). While the outputs included (total Revenues Y1, net short-term investments Y2, number of traded shares Y3), The method of analyzing the data envelope of the super-efficiency model was applied to 46 companies listed on the Iraqi Stock Exchange distributed over 7 different sectors during the period (2016-2020) using the volume returns model. The study found that there were 24 companies that achieved high efficiency during the year (2016), 18 companies during the year (2017), 25 companies during the year (2018), 22 companies during the year (2019), and 18 companies during the year (2020). The research assumed that part of the companies listed in the Iraq Stock Exchange achieved super efficiency during the research period, while the other part could not reach the level of super efficiency for that company. The research reached a number of recommendations, most notably: the need to work on developing the Iraqi stock market by providing human expertise that can keep pace with recent developments that work to guide investors in directing their shares to companies that are expected to achieve increased returns after a period of time. And the necessity of relying on one of the companies’ super efficiency models in order to benefit from the characteristics of these models in minimizing production requirements and achieving optimal use on the one hand and maximizing outputs on the other hand, because this leads to raising the super efficiency of these companies.
