  The political uncertainty caused by the instability of management and the political hypothesis leads to a market failure. In high-risk information environments where accounting information is less predictable, political uncertainty exacerbates market behavior. The purpose of this study is to investigate the political uncertainty caused by the volatility of management and size of the company under the influence of the capital market information environment against the rules of voluntary accruals and the capital cost of ordinary shares of companies. For this purpose, the data of 100 companies listed in Tehran Stock Exchange during the period 1387-1396 were examined and tested using combined data. The results show that the political uncertainty caused by management instability under the influence of the capital market information environment is negatively and significantly correlated with the cost of ordinary equity capital. Also, there is a positive and significant relationship between the political uncertainty associated with the size of the company affected by the capital market information environment and the cost of ordinary equity capital.
