Investigating the Relationship between Discretionary Accruals and Credit Rating by Considering the Moderating Effect of Managers' Narcissism.

Narcissistic managers with characteristics such as desire for fame and power seeking to protect their interests have the necessary motivation to be effective on the relationship between discretionary accruals and credit rating and, as a result, change the credit rating of companies to their desired rating. The purpose of the present study is to investigate the relationship between discretionary accruals and credit rating by considering the moderating effect of managers' narcissism. The statistical sample of the current research includes 113 companies listed on the Tehran Stock Exchange and 17 companies listed on the Iranian Foreign Exchange in the period of 2011-2021. The data of this research was collected by referring to the Kodal website, the website of the Iranian Statistics Center and Rahvard Novin software. Hypotheses were tested through multivariate regression models and generalized least squares approach using EViews 12 software. The results of the statistical test of research hypotheses confirm that discretionary accruals have a positive and significant effect on the credit rating of economic units. That is, with the increase of discretionary accrual items, the credit rating of economic units increases. Also, the findings of the research indicate that there is a moderating effect of managers' narcissism with three indicators of the size of managers' signatures, managers' cash bonus and managers' photo in the relationship between discretionary accruals and the credit rating of economic units. In other words, managers' narcissism based on the indicators of the size of managers' signatures, managers' cash bonus and managers' photos strengthens the positive relationship between discretionary accruals and credit rating. Based on these results, credit rating agencies are suggested to pay more attention to the narcissistic factors of managers and discretionary accruals in the credit rating process of economic units.
