The purpose of this paper is to examine the relationship between state ownership and firm profitability in developing countries by considering the endogenous nature of state ownership and firm profitability.

A simultaneous equation analysis is applied to study 232 Tunisian firms over the 2001-2013 period. This analysis is compared with OLS estimates to show its power in terms of an endogenous setting and its potential to improve estimation.

Unlike the OLS estimates that show a non-significant relationship between state ownership and firm profitability, the simultaneous equation analysis reveals a non-symmetrical concave relationship. Specifically, state ownership affects positively firm profitability when it is relatively small and negatively when state ownership dominates. Specification test indicates that both state ownership and firm profitability are endogenous. Furthermore, the simultaneous model’s explanatory power exceeds that of OLS estimates and proves to be a suitable estimation technique.

Taking into account public firms’ categorization, the authors implicitly examine the effect of privatization and corporatization on firm profitability. The findings imply that privatization is not the only solution to the operational problems of public firms, but an internal governance system restructuring can also be favorable for these firms.

In addition to focusing on a new database of developing countries, the case of Tunisian firms, the main empirical analysis is conducted by considering the endogeneity issue. Thus, the findings improve understanding of the role played by state ownership and suggest that a partial state control appears to be beneficial to firm profitability.

The purpose of this paper is to investigate the relationship between corporate governance mechanism and firm value of the listed companies in China. Does the better corporate governance lead to the higher firm value? Or does the higher firm value make it easy to choose a better governance mechanism? Or they affect each other? In other words, this paper tries to answer whether the corporate governance mechanism is only decided by institutional arrangement, or by market choice according to firm value or performance or by the interaction of institutional arrangement and market choice? It tries to answer whether institutional arrangement maximizes the firm value, or an invisible hand pushes them to arrive at its maximum.

This paper establishes an analytic framework of simultaneous equations based on causality, which includes five endogenous variables: ownership of larger shareholders, managerial ownership, director compensation, debt financing and firm value. It adopts 1,644 data samples from 274 Chinese listed companies in Shanghai and Shenzhen Stock Exchange during 2007- 2012 after the non-tradable shares reform. Ordinary least squares (OLS) estimation of single equation, 2SLS and 3SLS estimation of simultaneous equations are respectively done to show the differences of these three kinds of estimations.

The empirical results show that differences exist among OLS, 2SLS and 3SLS estimation. Finally, 3SLS estimation should be adopted because the OLS and 2SLS estimation are biased. There are endogenous relationships between corporate governance mechanism and firm value. Through the 3SLS estimation, it is found that first, ownership concentration and firm value affect each other positively. Second, managerial ownership and firm value affect each other positively; third, director compensation and firm value affect each other negatively, while director compensation and firm performance affect each other positively. Finally, debt financing level and firm value are negatively related to each other.

It means that ownership of large shareholders, managerial ownership, director compensation and debt financing in the Chinese listed companies are found to have a root in the interaction between institutional arrangement and market choice. It is also found that adverse selection occurs when creditors loan to the listed companies. Managerial compensation is positively related to accounting profit, but it is negatively related to firm value because managers increase profit due by earning management. This could only increase the accounting profits and obtain huge cash compensation, but not increase firm value and even harm the interests of shareholders.

This paper not only shows the difference between OLS and 2SLS estimation but also compares the estimation of 2SLS and 3SLS in terms of empirical methods. It gives answers to the following questions: whether the relationship is one-way causality or bilateral causality between ownership concentration, managerial ownership, director compensation and firm value; whether governance mechanism affects firm value by institutional arrangement, or market drives both of them to strike a balance by an invisible hand. In other words, does it make them arrive at equilibrium through the competitive selection process when shareholders, directors, managers and creditors attempt to maximize themselves of their interests?

The purpose of this paper is to explore whether the provision of non-audit services (NAS) by public accounting firms undermines audit quality. The study addresses this question by testing for an association between the provision of consulting services and auditor independence in listed companies.

The authors study if the magnitude of non-audit fees explains variations in earnings management by looking at the joint determination of non-audit fees, audit fees, and abnormal accruals using the SURE-regression estimation method.

Evidence from tested models suggests that audit services quality is uncompromised by the provision of NAS. In other words, high non-audit fees do not necessarily result in poor quality financial reporting.

A different research methodology and a different sample (e.g. non-listed companies) may lead to differing results. As the paper analyses only one country, generalizability of the results might be a limitation. There is no need to increase legal restrictions on the provision of consulting services by public accounting firms in order to better safeguard audit quality.

Consulting clients may be more confident to hire both audit and NAS with the same firm and can make a case before the general Shareholders’ meeting. By providing both audit and NAS, consulting firms obtain knowledge spillovers and synergies while appealing highly qualified professionals.

The use of simultaneous equations (SURE-regression) to establish the auditor-client relation allows us to better model theoretical relations between audit fees, non-audit fees, and abnormal accruals. Likewise, joint modeling takes account of correlations between the error terms of the individual models, yielding more efficient estimates than ordinary least squares. Performing this analysis in a non-Anglo-American country with low litigation risk is also a valuable contribution to extant literature.

Previous empirical studies on the nature of the relationship between ownership and corporate value have produced mixed results. Meanwhile, effective management of knowledge‐based intellectual capital has become a key factor to corporate success, both in firm performance and corporate value. Thus, this paper aims to reexamine the link among ownership, proxies for intellectual capital and corporate value in the emerging Taiwan market.

Using two‐stage least square estimation of panel data in a simultaneous equations framework, the authors focus on: What is the interdependent impact of ownership on corporate value through the mediating role of intellectual capital (IC)? Does ownership directly or indirectly (i.e. via IC) influence corporate value? Does it persist across industries?

The empirical results suggest that the relationship between ownership and corporate value mainly depends on industry characteristics and the nature of proxies for intellectual capital in the emerging Taiwanese market. Further, the impacts of ownership on corporate value in more traditional industries are even stronger, that is, there exists the direct impact of ownership mechanism on corporate value. Notably, for the high‐tech firms, ownership can indirectly affect corporate value through the moderating role of intellectual capital.

The implication reminds managers and investors not merely focusing on ownership mechanisms as the main value‐creation information, but a thorough review of IC should be made in order to avoid making incorrect decisions. The limitations suggest areas for further research. For instance, it is important to extend the role of intellectual capital (i.e. to employ other variables to proxy for IC) in exploring the interdependent impact of ownership on corporate value.

The paper potentially adds to ongoing research by extending the importance of the concept of IC in assessing the interdependent impact of ownership on corporate value.

This paper aims to investigate whether audit fees and financial report readability are bi-directionally related.

The authors test their hypotheses with empirical data. Specifically, they adopt a two-stage simultaneous equation regression model to assess the bi-directional relationship between audit fees and financial report readability.

While poor readability increases the fees charged by the auditor, higher audit fees improve the readability of the financial reports.

This study is based on US data. Future research may extend this study to other countries.

Poor financial report readability encumbers stakeholders of the firms. Understanding the interaction between financial report readability and audit fees will help both auditors and firm managers.

Audit committees aggressively negotiating for lower audit fees should be aware of the link of low audit fees, potentially indicative of poor quality, to less readable reports. Investors and regulators too should be concerned about this relationship, especially in instances when auditors low-ball audit fees or when firms aggressively negotiate for lower audit fees.

To the best of authors’ knowledge, this study is the first to document the bi-directional relationship between financial report readability and audit fees and assess the positive impact of audit fees on financial report readability.

The purpose of this paper is to present computer‐aided simultaneous signal and noise modeling and analysis for mm‐wave field‐effect transistors (FETs) based on scattering parameters approach.

A mm‐wave FET is modeled as three active‐coupled transmission lines, and the developed wave approach is applied to this model to calculate both signal and noise performances of the device.

The measurements show a good match with the calculated data from the point of view of both signal and noise performances of the device.

This CAD‐oriented analysis and modeling can be easily applied to the mm‐wave simulators to improve the simultaneous signal and noise optimization, modeling and analysis of mm‐wave devices, especially for traveling wave transistors in which the distributed model seems to be more exact than the usual lumped models. Also the proposed routine compared to the admittance approach is conceptually more compatible with scattering representations of active and passive circuits. The developed algorithm has been applied successfully to mm‐wave MESFETs and HEMTs.

The first alternative is to enrich shareholding by management. The basic theory of this research is the agency theory. This study aims to examine the institutional ownership, dividend policy, debt policy, and risk that are interconnected directly or indirectly. The research sample was a non-financial company from 2010 to 2014. Four variables will be tested using Two-stage Least Square (2SLS) in the SPSS application. The result of this study represents the overall interdependency relationship among institutional ownership, dividend policy, debt policy, and risk. The research outcome signifies an interdependency relation for endogenous variables, even if some exogenous variables have no significant relation. In addition, the effects of substitution between institutional ownership and dividend policy, debt policy and dividend policy, and institutional ownership and risk. Meanwhile, institutional ownership and dividend policy, risk and dividend policy, and risk and debt policy have no substitution effect.

This study aims to examine the signalling hypothesis of dividends by testing empirically the market reaction to dividends announcements. Furthermore, this study aims to examine the information content of dividends announcements with respect to future earnings changes for a sample of Jordanian industrial firms over the period 2009 to 2015.

The authors mainly used the event study methodology to examine the market reaction to dividend release announcements. The market model is used to generate the expected returns. Also, the t-test is used to examine the significance of the mean and cumulative abnormal return. Furthermore, a simultaneous-equation model developed by Nissim and Ziv (2001) and Grullon et al. (2005), applying the two-stage least squares (2SLS), is used to examine the relationship between dividends changes and future earnings changes.

The results reveal consistency with the limited extant empirical evidence for developing markets and provide some new insights for Jordanian listed firms that support the signalling hypothesis. In applying the event study methodology, the information content of dividends shows that there is a significant positive market reaction to dividends announcements. The study’s findings also present a strong relationship between dividends announcements and profitability in the year of announcements and the subsequent year, whereas this relationship does not exist in the second year. The findings show that there is value-relevance for dividends, suggest that investors recognize the signalling purpose and discern that dividends announcements are useful in predicting favourable and unfavourable future earnings in the short run (the same year and subsequent year) and also show that managers may use dividends to signal earnings prospects in anticipation of expected future market benefits.

The findings of this study could have significant policy implications. The support of a signalling effect implies an existence of information symmetry, at least theoretically, between management and investors. On the other side, this study could not reflect the levels of inside ownership or the existence of signalling substitutes even though these findings could have implications for Jordan’s existing corporate governance practices and firms’ disclosure environment. The results are specific to Jordan, but they do shed light on the generality of the rival models of dividend policy. Many of the structural characteristics of the capital market in Jordan are, however, also present in other emerging markets. The results from this study may, therefore, help provide the basis for comparative research both in the region and in other emerging markets.

The support of the signalling effect implies the existence of information symmetries, at least theoretically, between management and investors. These findings could have implications for Jordan’s existing corporate governance practices and firms’ disclosure environment.

This paper contributes to the literature by providing a workable test for the dividend signalling hypothesis, applying a simultaneous-equation model that incorporates the market reaction to dividends announcements and future earnings changes. Moreover, this paper uses a recent data set of dividends announcements in Jordan. This study provides additional insight to support the signalling hypothesis in emerging markets. Overall, current and previous studies have focused typically on investigating dividend policy in developed markets, especially the US and European markets, although there has been limited analysis of dividends changes on earnings changes for developing markets.

Tests a new series of models which attempt to describe the relationship between advertising and sales. Describes an attempt to obtain information of this kind by investigating the effect of advertising on sales and brand shares. States that a number of researchers are now attempting to develop models to explain the workings of the market for a particular product. Emphasises that the prime area of interest of the study is the effect of advertising on sales and brand shares. States the study does not have the objective of constructing a complete marketing model involving all the variables that are thought to influence a brand's share of a product. Concludes that many results herein are disappointing, but it is perhaps too optimistic to expect the models dealt with earlier to be successful.
