State ownership has been common especially in industries with restricted competition. In Russia, state-controlled firms represent around 41 percent of the market value of all listed firms (Deloitte, 2015). Yet, there is a significant gap in the literature regarding the effects of various forms of government control in listed firms. The purpose of this paper is to fill this gap by exploring the impact of the complexity of state ownership and competition on the performance of Russian listed firms.

The sample consists of data for 72 firms (360 firm-years) in the Russian MOEX broad market index during 2011–2015. The complexity of state ownership is captured by studying forms of state control including majority/minority, direct/indirect, federal/regional, mixed structures and golden shares.

The authors find significant differences in performance relating to different forms of state ownership. State control is negatively related to firm valuation and the sales/employees ratio. Performance is weakest when state ownership takes the form minority, regional or direct ownership. State control through golden shares typically outperforms other state-controlled firms. The authors find indications of employment prioritization beyond the economical optimum. In addition, the relation between state ownership and profitability becomes positive in sectors where state firms appear to enjoy lower competition.

While the effects of state ownership have been studied on many markets, there is a lack of studies on the effects of different forms, or the complexity, of state ownership beyond direct and indirect ownership. The authors contribute to the literature on the performance effects of state ownership by studying a multitude of forms of governmental ownership as well as the role of competition in Russia. Especially the profitability of state-controlled firms is significantly affected by industry characteristics. Implications of the results are discussed both from firm and policy maker perspectives.

The paper aims to explore how the undue state control leads to the weak stock market in China. It analyzes how the undue state control is exerted in some key areas in the Chinese stock market. This paper intends to expand the existing literature in the relationships among law, politics, and economy.

This paper mainly adopts the exploratory method to analyze the undue state influences. Under some circumstances, comparative study and historical explanation are also adopted.

The paper suggests that to create a strong stock market and facilitate the development of the listed companies and the whole economy, the state should first release its control on the stock market.

Various fields are contained in a stock market, in most of which the undue state control can be observed. In this paper, only some key ones are explored. Further research on other fields and if possible more first‐hand data are necessary.

This paper not only offers an answer to concerns on the various misconducts in the inefficient Chinese stock market and helps to realize the possible ways out of such dilemma, but also it offers implications for other emerging economies.

The on‐going debate on the role of common‐law versus civil‐law system in the capital market may have ignored the state involvement. This paper indicates that it is the undue state control rather than the legal system that leads to the weak stock market in China.

The purpose of this paper is to link literature on China’s real estate sector and the impact of governance, ownership and political connectedness on firm financial performance. Whether these factors impact listed real estate firms differently to firms in other industry sectors is identified.

The paper uses pooled 2008-2013 data on A-share firms. Tobin’s Q captures firm financial performance. Explanatory variables include corporate governance, ownership, local government political connectedness, accounting data and ultimate control. Two-way interactions are estimated between real estate and ownership, governance, political connectedness and other variables. Three-way interactions are estimated between real estate, ownership, control and political connectedness. Year and industry fixed effects are absorbed.

Industry concentration and proportion of state ownership appear to positively impact performance. Firm size, gearing and greater foreign ownership appear to negatively impact performance. However, differences are identified for real estate firms, in which state control and gearing positively impact performance. Greater state and foreign ownership as well as supervisory board size negatively impact performance. Finally, state control in the presence of local government connections negatively impacts performance, while greater state ownership in the presence of local government connections positively impacts performance.

A lack of empirical evidence on the impact of corporate governance, ownership structures and political connectedness on firm performance in China’s real estate sector is addressed. Importantly, relationships among these factors and the financial performance of China’s listed real estate firms differ to those of firms in other industries.

The purpose of this paper is to explore the demand for conditional accounting conservatism from equity shareholders in state-controlled firms.

This study presents empirical investigation of firms listed on Hong Kong Stock Exchange from 1997 to 2013.

The first finding is the extent of conditional conservatism in state-controlled firms increases when the leverage ratio decreases. It is also found that the high control rights held by the government in state-controlled firms are associated with high conditional conservatism. In addition, further analyses document the an offsetting effect between high control rights and firm leverage; a reinforcing effect between high control rights and year of incorporation after 1992; and a substituting effect between high control rights and dividend payments.

These findings suggest that the demand from equity shareholders, in addition to the debt demand, can be an important determinant of conditional conservatism and examination of these differing sources of demand can enhance the understanding on accounting conservatism in state-controlled firms.

This paper examines the impact of state control on stock price crash risk given whether and how ownership structure affects stock price crash risk is relatively underexplored.

The sample includes 2,285 Chinese firms listed in the Shanghai and Shenzhen Stock Exchanges. Panel data is used for conducting the analysis and endogeneity is addressed with instrumental variable estimation and by testing how stock price crash risk is affected when the ultimate controller changes from a private-owned company to a state-owned enterprise.

The authors find that state control is negatively associated with future stock price crash risk. The mechanism analysis shows that state control reduces stock price crash risk through the implementation of conservative corporate policies. Furthermore, the impact of state control is more pronounced with more intensive state involvement, e.g. in strategic industries and when a company's ultimate controller is a non-corporate government agency or the central government.

This paper enriches the literature on the controversy of the role of state control and the results of this study highlight the importance of the conservatism of state control on reducing stock return tail risk. The authors also add to the literature on the importance of the policy-risk sharing effect of state ownership.

The purpose of this paper is to test the political costs hypothesis in emerging economies characterized by interventionist governments and weak protection of property rights. The paper uses executives’ political connection and state control to measure firms’ political costs.

Based on a sample of Tunisian firms, univariate and multivariate analyses are used to test whether firms’ political costs have any impact on earnings management.

The empirical analysis indicates that the executives’ political connection is not directly related to earnings management. However, the interaction between executives’ political connection and the state control affects the firm’s sensitivity to political pressure and its earnings management practices. More specifically, this study provides evidence that non-connected firms and state-controlled firms attempt to use accounting policies to decrease their earnings especially during periods of the former government when they had to face high political costs. This finding is robust to comparing means of political cost indicators between different groups. Indeed, private firms with political connection enjoy a significantly lower insurance right, tax and donations and grants compared to other firms.

This study provides empirical evidence for the specific application of accounting theory in emerging economies.

Political influence may be an important criterion that will be used by auditors and investors to appreciate and detect specific manipulations of accounting earnings. Similarly, regulators should be aware of the political factors effect on discretionary behavior of managers to provide appropriate rules and standards.

The study is a pioneer in proving that a firm’s size is not always a suitable measure of its political cost. It extends the accounting literature on the role of political economy in the application of the political costs hypothesis. This hypothesis is confirmed in emerging economies by providing new and significantly measure of firms’ political costs

Many transition economies are former socialist planned economies and have undergone market reforms of their financial sector to signal their transition towards democracy. However, governments in these countries have been reluctant to relinquish the pre-existing controls on economy and have adopted nuanced and sophisticated approaches to retain control. In such context, scholars may find it challenging to investigate the role played by the state in the success or failure of attempted market reforms. This work investigates the different forms of state-induced accounting controls that may preserve the status quo within the economy during transition, using Myanmar as an example.

The authors adopted a longitudinal qualitative research method aiming to reveal the very processes and mechanisms used by the banks and their evolution over time. This method is in accordance with the historical institutionalist perspective that they have applied within this research.

The authors found that the Myanmar government embarked on the privatisation of their financial sector from 1990 to 2016 as a major public sector reform initiative. Under the guise of market reforms, it used both state-led and market-led controls to emulate and retain the socialist banking model where banks are used to fund the immediate government's budget deficits. This created a series of intended and unintended consequences, resulting in the ultimate failure of the government's market reforms.

Previously, research on public sector management accounting in emerging economies was not relying consistently on using theory. The relative limited theorisation led to gaps when attempting to understand and explain the opaque forms of state control mechanisms in transition economies. By applying historical institutionalist perspective, and a more theory-driven, reflective approach to the interpretation of the data collected, the authors have provided a deeper insight and understanding on how different forms of state controls can emerge, adapt and persist in transition economies such as Myanmar.

The authors demonstrated that though the state may have implemented market reforms to signal regimes change, this does not necessarily mean that the government has relinquished their control on the economy. The state could take a more sophisticated, covert approach towards state controls leading to both intended and unintended consequences. Thus, even if the state's preferences change, the decisions cannot be easily reversed, as path-dependent state controls may have become pervasive affecting any further institutional and policy developments. Thus, the authors suggest that governments in both transition and developed economies should be cautious when enacting regulations on corporate control.

In this paper, the authors have applied a historical institutional perspective in their analysis instead of the more widely used sociological, institutionalist approach. This allowed authors to harness rich longitudinal data indicating that market reforms and their success or failure should be examined as an ongoing process rather than a completed action. This is especially important in transition economies where the state may be unwilling to renounce the existing controls on the industry and may resort to more opaque forms of state control, eventually obstructing the intended reforms.

The paper aims to examine accounting changes in the Ashanti Gold Corporation (AGC) in Ghana over 120 years from pre-colonialism to recent times and whether the framework of management accounting transformations in Hopper et al. (2009) is applicable.

Mixed data sources are used, namely, interviews, some observations of practices, historical documentation, company reports and research papers and theses. The results are categorised according to the periods and contextual factors in the Hopper et al. framework to test whether it matches the data collected.

Despotic controls with minimal management accounting but stewardship accounting to the head office in London prevailed under colonialism. Upon independence state, capitalist policies descended into politicised state capitalism. Under nationalisation, the performance of mines deteriorated, and accounting became decoupled from operations. In the early 1980s, fiscal crises forced Ghana’s government to turn to the World Bank and International Monetary Fund for loans. This period marked a gradual transformation of AGC into a foreign multinational, organised along divisional lines and currently exercises despotic control through supply chain management that renders labour precarious and is neglectful of corporate social accounting issues.

The work challenges neo-classical economic prescriptions and analyses of accounting in developed countries by indicating its neglect of the interests of other stakeholders, especially labour and civil society. Accounting is important for development but the article infers other forms may better serve the public interest.

The paper tests the Hopper et al. framework with respect to a large private multinational in the commodity sector over an extended period, which differs from the case studies drawn on originally.

This article aims to identify management practices that evidence how internal control have been considered essential, from the edition of the State Constitutional Amendment no. 75 of 2012, within the public administration of the executive branch of the State of Ceará, during the period 2012–2021.

The study relates the identified management practices to COSO (The Committee of Sponsoring Organizations) methodology “Internal Environment” component categories. The research is classified as basic, exploratory and bibliographic, on the theme of internal control in scientific articles published between 2015 and 2021, and documental, carried out through official documents, including the 27 Brazilian constitutions.

Existence of management practices that corroborate the essentiality of internal control in Ceará.

The study is limited to evidencing the control practices implemented in Ceará, not evaluating them as to their quality.

Contributions on control on constitutional-legal bases for other Brazilian Federation States.

Possibility of introducing the research theme into various branches of scientific knowledge, such as political science and contributing to public organizations to implement policies with the proper application of resources for the benefit of society.

The originality of the research is in demonstrating the essentiality of internal control in the State of Ceará, from the edition of management acts performed by the executive branch, based on Constitutional Amendment 75 of 2012, which did not become a dead letter of the law, enabling other states of the federation to do the same.

Voltage source inverter-fed permanent magnet synchronous motors (VSI-PMSMs) are widely used in industrial actuation and mechatronic systems in water pumping stations, as well as in the traction of transportation systems (such as electric vehicles and electric trains or ships with electric propulsion). The dynamic model of VSI-PMSMs is multivariable and exhibits complicated nonlinear dynamics. The inverters’ currents, which are generated through a pulsewidth modulation process, are used to control the stator currents of the PMSM, which in turn control the rotational speed of this electric machine. So far, several nonlinear control schemes for VSI-PMSMs have been developed, having as primary objectives the precise tracking of setpoints by the system’s state variables and robustness to parametric changes or external perturbations. However, little has been done for the solution of the associated nonlinear optimal control problem. The purpose of this study/paper is to provide a novel nonlinear optimal control method for VSI-fed three-phase PMSMs.

The present article proposes a nonlinear optimal control approach for VSI-PMSMs. The nonlinear dynamic model of VSI-PMSMs undergoes approximate linearization around a temporary operating point, which is recomputed at each iteration of the control method. This temporary operating point is defined by the present value of the voltage source inverter-fed PMSM state vector and by the last sampled value of the motor’s control input vector. The linearization relies on Taylor series expansion and the calculation of the system’s Jacobian matrices. For the approximately linearized model of the voltage source inverter-fed PMSM, an H-infinity feedback controller is designed. For the computation of the controller’s feedback gains, an algebraic Riccati equation is iteratively solved at each time-step of the control method. The global asymptotic stability properties of the control method are proven through Lyapunov analysis. Finally, to implement state estimation-based control for this system, the H-infinity Kalman filter is proposed as a state observer. The proposed control method achieves fast and accurate tracking of the reference setpoints of the VSI-fed PMSM under moderate variations of the control inputs.

The proposed H-infinity controller provides the solution to the optimal control problem for the VSI-PMSM system under model uncertainty and external perturbations. Actually, this controller represents a min–max differential game taking place between the control inputs, which try to minimize a cost function that contains a quadratic term of the state vector’s tracking error, the model uncertainty, and exogenous disturbance terms, which try to maximize this cost function. To select the feedback gains of the stabilizing feedback controller, an algebraic Riccati equation is repetitively solved at each time-step of the control algorithm. To analyze the stability properties of the control scheme, the Lyapunov method is used. It is proven that the VSI-PMSM loop has the H-infinity tracking performance property, which signifies robustness against model uncertainty and disturbances. Moreover, under moderate conditions, the global asymptotic stability properties of this control scheme are proven. The proposed control method achieves fast tracking of reference setpoints by the VSI-PMSM state variables, while keeping also moderate the variations of the control inputs. The latter property indicates that energy consumption by the VSI-PMSM control loop can be minimized.

The proposed nonlinear optimal control method for the VSI-PMSM system exhibits several advantages: Comparing to global linearization-based control methods, such as Lie algebra-based control or differential flatness theory-based control, the nonlinear optimal control scheme avoids complicated state variable transformations (diffeomorphisms). Besides, its control inputs are applied directly to the initial nonlinear model of the VSI-PMSM system, and thus inverse transformations and the related singularity problems are also avoided. Compared with backstepping control, the nonlinear optimal control scheme does not require the state-space description of the controlled system to be found in the triangular (backstepping integral) form. Compared with sliding-mode control, there is no need to define in an often intuitive manner the sliding surfaces of the controlled system. Finally, compared with local model-based control, the article’s nonlinear optimal control method avoids linearization around multiple operating points and does not need the solution of multiple Riccati equations or LMIs. As a result of this, the nonlinear optimal control method requires less computational effort.

Voltage source inverter-fed permanent magnet synchronous motors (VSI-PMSMs) are widely used in industrial actuation and mechatronic systems in water pumping stations, as well as in the traction of transportation systems (such as electric vehicles and electric trains or ships with electric propulsion), The solution of the associated nonlinear control problem enables reliable and precise functioning of VSI-fd PMSMs. This in turn has a positive impact in all related industrial applications and in tasks of electric traction and propulsion where VSI-fed PMSMs are used. It is particularly important for electric transportation systems and for the wide use of electric vehicles as expected by green policies which aim at deploying electromotion and at achieving the Net Zero objective.

Unlike past approaches, in the new nonlinear optimal control method, linearization is performed around a temporary operating point, which is defined by the present value of the system’s state vector and by the last sampled value of the control input vector and not at points that belong to the desirable trajectory (setpoints). Besides, the Riccati equation, which is used for computing the feedback gains of the controller, is new, as is the global stability proof for this control method. Comparing with nonlinear model predictive control, which is a popular approach for treating the optimal control problem in industry, the new nonlinear optimal (H-infinity) control scheme is of proven global stability, and the convergence of its iterative search for the optimum does not depend on initial conditions and trials with multiple sets of controller parameters. It is also noteworthy that the nonlinear optimal control method is applicable to a wider class of dynamical systems than approaches based on the solution of state-dependent Riccati equations (SDRE). The SDRE approaches can be applied only to dynamical systems that can be transformed to the linear parameter varying form. Besides, the nonlinear optimal control method performs better than nonlinear optimal control schemes which use approximation of the solution of the Hamilton–Jacobi–Bellman equation by Galerkin series expansions.
