Audit Quality Moderating Effects On The relation between Accounting Information Quality and Investment Efficiency

This study is aimed to investigate audit quality effects on the relation between accounting information quality and investment efficiency. Audit quality is measured using observable variables of reports type, expertise, and audit tenure period. The sample consists of 864 year-firm over the period from 2009 to 2017 and the study method is multivariate regression. The results show that the external high quality audit is a mechanism decreasing challenges from agency costs and improper choice and thus enhancing investment efficiency, through improving accounting information quality. Also, the results of the research indicate that reducing overinvestment and underinvestment through improving the quality of accounting information is more effective in firms with higher audit quality
