In this paper, we describe the trend of market concentration, the formation of strategic groups in Russian industry, principles of integration of firms in strategic groups, and the reasons for increase of market concentration. Purpose to propose the methods of measuring industry concentration in terms of coordination. Methodology: methods of system analysis, economic analysis, the methodological approaches of the theory of industrial organization, regression analysis. Results: Authors provide the methods of measuring industry concentration in terms of coordination. Authors established laws of formation of strategic groups (coalitions). The relationship between the concentration rate and business cycle sensitivity of firms in Russian industry was described. Practical implications: The methods of measuring industry concentration is of interest to economists, business strategists, and government agencies.

Policymakers and regulators have been concerned about the impact of audit market concentration resulting from decline in the number of audit firms due to mergers and the demise of Arthur Andersen. In this paper we find a positive association between audit market concentration (Herfindahl index) at the MSA level and audit quality (measured by discretionary accruals and the Dechow-Dichev (2002) measure of accrual quality). We control for fixed year effects, therefore our results are unlikely to be affected by the increase in concentration due to Andersen's demise contemporaneous with an increase in audit quality because of regulatory measures such as SOX. Our results are robust to alternative concentration and audit quality measures, and several sensitivity tests attempting to rule out omitted variables correlated with client firms' MSA location or attributes of clients and auditors. Our results are also robust to controls for endogeneity between audit market concentration and audit quality. Our evidence therefore supports the Government Accountability Office (2003, 2008) conclusions that increased audit market concentration is not currently a cause for concern.

Statutory audit is designated to protect the public interest and has a significant impact on the overall economy. There are concerns that the Big Four audit firms have become too dominant and that the collapse of one of these firms would disrupt the whole financial system. In terms of revenues received, the total market share of the Big Four audit firms for listed companies exceeds 90% in a vast majority of European Union Member States. Prior studies have shown that high audit market concentration limits the choice of auditor for large companies and sets a high barrier of entry for mid-tier audit firms, while the effect on audit quality and audit fees is still unclear. Therefore, the regulators are considering reforms to dilute the Big Four's dominance and improve competition in the audit market. The paper reviews the proposed and implemented measures that are the most common, together with their advantages and drawbacks. In addition, the characteristics of the audit market in Croatia are investigated, with a focus on market concentration measured by standard measures such as the Concentration rate, the Herfindahl Hirschman Index and the Gini coefficient. According to market shares based on total clients' assets and revenues, the audit market for listed companies is moderately to highly concentrated, with a decrease in the five-year period (2013 compared to 2008).
