On the other hand, it can be expected that the improvement of economic data (including market value added) will also strengthen the predictability of managers.This study investigates the two-side relationship between management ability and market value added using the method of Simultaneous Equations. For this purpose, the required information for the period of 2014-2018 was collected for 105 companies and the research hypothesis was tested using the method of Simultaneous Equations (granger-causality). The results showed significant two-side relationship between management ability and MVA, also; two side granger-causality between management ability and economic value added: p-value (0.000), with 95 percent statistical significance.
