Accounting and beyond budgeting principles changes in the public sector: A review of concepts and literature with emphasis on institutional isomorphism

In recent decades, significant reforms and changes have taken place in the public financial management sector, especially in the field of public sector accounting and budgeting. These reforms, such as extra-budgetary, include changes to public accounting policies and procedures. In fact, the metabudget principle is an adaptable and largely decentralized management model, as well as one of the most prominent management innovations of the 21st century, in which companies use it to overcome the inherent problems of traditional annual budgeting. The purpose of this study is to describe the process of accounting changes and extra-budgetary principles in the public sector, which has been done by reviewing the existing literature. A review of previous studies shows that the implementation of extra-budgetary principles is not merely a symbolic innovation, and changes at the government level have led to changes in structures and systems at the organizational level, as well as the adoption of this principle. In addition, the present study pays special attention to institutional isomorphism and its approaches and briefly addresses the international standards of public sector accounting as well as its advantages and challenges.
