Abstract

Purpose

The purpose of this paper is to reveal the limitations of h-index in assessing research performance through citation analysis and suggest two new indexes called prime index (P-index) and value added index (V-index), which are simpler to compute than g-index and more informative. For more serious research performance evaluation, analytic hierarchy process (AHP) methodology is proposed.

Design/methodology/approach

The methodology adopted is to compare existing indexes for citation-based research assessment and identify their limitations, particularly the h-index, which is most commonly employed. It gives advantages of g-index over h-index and then proposes P-index which is simpler to compute than g-index but is more powerful in information content than g-index. Another V-index is proposed on a similar philosophy as P-index by considering total number of citations/author. For serious evaluation of finite candidates for awards/recognitions, a seven-criteria-based AHP is proposed. All new approaches have been illustrated by drawing raw data from Google scholar-powered website H-POP.

Findings

This paper demonstrates over-hype about use of h-index over g-index. However, it shows that newly proposed P-index is much simpler in computation than g but better than g-index. V-index is a quick way to ascertain the value added by a research scientist in multiple-authored research papers. P-index gives a value 3–4 percent higher than g and it is holistic index as it uses complete data of citations. AHP is a very powerful multi-criteria approach and it also shows g-index to be a more important factor, whereas h-index is the least important but frequently used approach. It is hoped that the findings of this paper will help in rectifying the misplaced emphasis on h-index alone.

Research limitations/implications

The research focus has been to suggest new faster, better methods of research assessment. However, a detailed comparison of all existing approaches with the new approaches will call for testing these over a large number of data sets. Its limitation is that it has tested the approaches on 5 academics for illustrating AHP and 20 researchers for comparing new indexes with some of the existing indexes. All existing indexes are also not covered.

Practical implications

The outcomes of this research may have major practical applications for research assessment of academics/researchers and rectify the imbalance in assessment by reducing over-hype on h-index. For more serious evaluation of research performance of academics, the seven-criteria AHP approach will be more comprehensive and holistic in comparison with a single criterion citation metric. One hopes that the findings of this paper will receive much attention/debate.

Social implications

Research assessment based on proposed approaches is likely to lead to greater satisfaction among those evaluated and higher confidence in the evaluation criteria.

Originality/value

P- and V-indexes are original. Application of AHP for multi-criteria assessment of research through citation analysis is also a new idea.

Abstract

Purpose

The purpose of this paper is to examine the relation between managerial entrenchment and dividend policy for a large number of US industrial firms and examine the relative importance of three competing explanations behind the empirical association between managerial entrenchment and dividend policy, namely, the entrenchment irrelevance hypothesis, the dividend signaling hypothesis, and the optimal entrenchment hypothesis.

Design/methodology/approach

Utilizing all firms in the Investor Responsibility Research Center database, Compustat and center for research in security prices (CRSP), this paper investigates firm's propensity to pay dividends based on various logit and Tobit regressions as a function of managerial entrenchment measured by Gompers et al. G index after controlling for known determinants of firms' dividend decisions during the period from 1990 to 2003.

Findings

Results show that firms with entrenched managers are more likely to pay dividends. Their high propensity to pay persists over time. A large cash reserve can be used to deter hostile takeovers. Paying dividends reduces cash holdings, leaving the firm more vulnerable to hostile takeovers. In equilibrium, value‐maximizing firms with weak investment opportunities provide managers against takeovers to induce them to distribute cash rather than build a warchest against unwanted takeovers.

Originality/value

The main finding confirms the belief that firms choose a combination of anti‐takeover provisions and dividend policy to maximize shareholder value, evidence in favor of the optimal entrenchment hypothesis.

Abstract

Purpose

Potential ethnocentric biases in stated preference journal rankings are reviewed and revealed preference ranking methods are investigated. The aim of the paper is to identify an approach to ranking journals that minimises ethnocentric biases and better represents the international impact of research.

Design/methodology/approach

Coverage of marketing journals in Ulrich's, EBSCO, SSCI, JCR, Scopus and Google Scholar is explored. Citing references to 20 articles are analysed to determine citation time lags and explore the content of SSCI, Scopus and Google Scholar. To further review the extent of citation coverage, h‐index scores are generated for ten marketing journals using data from SSCI, Scopus and Google Scholar. In total, 36 marketing journals are ranked using the g‐index and Google Scholar data and results are compared to ten published rankings.

Findings

Stated preference ranking studies of marketing journals rely on US‐based respondents. The coverage of EBSCO, SSCI, JCR and Scopus databases is not representative of marketing's literature as they have few international sources, and a disproportionate coverage of US‐based journals. Google Scholar provides broader international coverage. The Impact Factor may be inappropriate for marketing journals as a large proportion of citations occur more than five years post‐publication. Results indicate that the g‐index is a superior approach to measuring the impact of marketing journals internationally.

Practical implications

Exposure of the limitations in existing ranking methods should encourage improvements in the development and use of journal rankings.

Originality/value

The investigations present original evidence to support long‐term concerns about approaches to journal ranking and citation analysis.

Abstract

Purpose

To improve the deficiencies of the existing journal influencing evaluation indexes, which have single influencing factors and are greatly affected by the number of papers published, this paper proposes a new evaluation of the journal influence method based on the RA index.

Design/methodology/approach

In the metrics create, the paper introduces the RA index for evaluating the impact of authors and analyzing its feasibility in journal evaluation. Then the RA index is divided by the number of journal's published papers to obtain the RAQ index to evaluate journal impact. In the metrics analysis, the authors analyze the statistical characteristics of the RAQ index using statistical analysis, and t-test, Roc curve and PLS were used to analyze the relationship between the RAQ index and other indicators.

Findings

Empirical results show that the RAQ index can effectively identify high-quality journals and reduce the number of published papers on journal evaluation. The empirical results show that the RAQ index has higher stability and discrimination than the h-index and g-index. Compared with other indexes, the RAQ index has better evaluation effects and statistical characteristics.

Originality/value

The current study proposes journals' RAQ index, which integrates the influence of high-, low- and zero-cited papers. It solves the problem of the virtual high of the h-type index. The findings will contribute to the evaluation of journal influence by offering a new research idea that facilitates the fairness and rationality of journal evaluation.

Abstract

Purpose

This paper builds on the “Law and Finance” theory and aims to examine the effect of the legal and institutional environment on the governance–performance relationship in the context of non-US firms. More precisely, it examines whether and how the country’s legal system and the level of investor protection interact with the firm-level corporate governance and affect firm performance.

Design/methodology/approach

The authors used the “G-Index” governance score developed by the Governance Metrics International rating for a sample of 12,728 firm-year observations from 23 countries over the 2009–2016 period.

Findings

The results show that the interaction between the country-level institutions and corporate governance system significantly affect the firm performance. In particular, the findings indicate that firms operating in common law countries tend to exhibit a positive valuation effect and higher performance than firms with a comparable corporate governance level operating in civil law countries. More precisely, the authors find that in common law countries, higher investor protection with enhanced corporate governance is associated with better firm performance. However, firms operating in civil law countries with weaker investor protection and a comparable corporate governance level tend to experience a negative valuation effect.

Originality/value

The findings suggest that the institutional and legal environment is crucial and important in determining the value-maximizing level of good governance practices. Managers and regulators should carefully analyze the cost of these initiatives and should coordinate it with the needs of the country’s legal system. The challenge for the company will be how to adjust its corporate governance strategy according to the needs and demands of the country’s legal system in which the company operates to improve its performance. The regulators should ensure a fit between the specifics of the national legal and institutional environment and corporate governance standards and practices.

Abstract

Purpose

The purpose of this paper is to investigate the effect of corporate governance strength as measured by the Gompers governance index (gindex) and other related factors on corporate risk as measured by implied volatility of returns.

Design/methodology/approach

The research incorporates implied volatility as the measure of risk, as compared to earlier studies that have used historic volatility measures. Governance variables include the Gompers Index, as well as other measures to control for firm size, ownership and leverage.

Findings

The findings indicate that corporate risk is significantly inversely‐related with the gindex, which essentially gauges how extensively antitakeover provisions are adopted by a firm. Firm size is the other variable significant in both univariate and multivariate models. Financial leverage and the percentage of outsiders on the board are significantly related to firm risk when not controlling for other factors. Board percentage of voting power does not appear to affect firm riskiness statistically.

Research limitations/implications

Future research needs to examine specifically why higher takeover defenses lead to lower implied volatility. This includes exploring whether the lower level of expected volatility is due to lower levels of takeover activity or whether firms with poor governance assume a suboptimal amount of risk.

Originality/value

The paper contributes to the literature by the use of implied volatility as the measure of risk. The results are robust and provide further support for the relationship between corporate governance and risk. While counter to initial expectations, these results suggest, at the very least, a firm with good governance may not necessarily have low implied volatility in its stock price.

Abstract

Purpose

Bibliometrics is one of the research fields in library and information science that deals with the analysis of academic entities. In this regard, to gauge the productivity and popularity of authors, publication counts and citation counts are common bibliometric measures. Similarly, the significance of a journal is measured using another bibliometric measure, impact factor. However, scarce attention has been paid to find the impact and productivity of conferences using these bibliometric measures. Moreover, the application of the existing techniques rarely finds the impact of conferences in a distinctive manner. The purpose of this paper is to propose and compare the DS-index with existing bibliometric indices, such as h-index, g-index and R-index, to study and rank conferences distinctively based on their significance.

Design/methodology/approach

The DS-index is applied to the self-developed large DBLP data set having publication data over 50 years covering more than 10,000 conferences.

Findings

The empirical results of the proposed index are compared with the existing indices using the standard performance evaluation measures. The results confirm that the DS-index performs better than other indices in ranking the conferences in a distinctive manner.

Originality/value

Scarce attention is paid to rank conferences in distinctive manner using bibliometric measures. In addition, exploiting the DS-index to assign unique ranks to the different conferences makes this research work novel.

Abstract

Purpose

The purpose of this paper is to develop a ranking of knowledge management and intellectual capital academic journals.

Design/methodology/approach

A revealed preference, also referred to as citation impact, method was utilized. Citation data were obtained from Google Scholar by using Harzing's Publish or Perish tool. The h‐index and the g‐index were employed to develop a ranking list. The revealed preference method was compared to the stated preference approach, also referred to as an expert survey. A comprehensive journal ranking based on the combination of both approaches is presented.

Findings

Manual re‐calculation of the indices reported by Publish or Perish had no impact on the ranking list. The revealed preference and stated preference methods correlated very strongly (0.8 on average). According to the final aggregate journal list that combined stated and revealed preference methods, Journal of Knowledge Management and Journal of Intellectual Capital are ranked A+, and The Learning Organization, Knowledge and Process Management, and Knowledge Management Research & Practice are ranked A.

Research limitations/implications

This study was the first of its kind to develop a ranking system for academic journals in the field based on the journals' citation impact metrics. This list is vital for knowledge management and intellectual capital academics for tenure, merit, and promotion decisions. It may also help them achieve recognition among their peers and colleagues from other disciplines.

Practical implications

The proposed ranking list may be fruitfully employed by knowledge management and intellectual capital practitioners, librarians making journal subscription decisions, academics looking for best outlets, and various academic committees.

Originality/value

This paper represents the first documented attempt to develop a ranking of knowledge management and intellectual capital academic journals by using the h‐index and the g‐index that reflect journal citation impact.

Abstract

Globalization is a process of interaction and integration among the countries, their people, their businesses, and their governments. It is a change driven by international trade, implemented by various policies and aided by modern technology. It has impacts on the environment, culture, political systems, economic development and prosperity, and human physical well-being in societies around the world. But there can be some negative impacts as well. One possible outcome of globalization of all sorts can be the income inequalities. Objective of this chapter is to search for any such connection. Gini coefficient, unemployment rate, Below Poverty Line (BPL) is taken to understand the extent of inequalities in different countries. Outcome shows some countries do not show any association between globalization and income inequalities; some do. Therefore, there are some other variables which influence the above relationship. This chapter tries to identify all such background factors. It reveals that factors like level of development, demographic structure, urbanization, adult and tertiary level of education and government expenditure share in higher education play important roles. All these have different magnitudes of impacts on change in income distribution due to the initial process of globalization.

Abstract

Deregulation shifts the responsibility for mitigation of agency problems from the regulatory parties to the firms' shareholders. We investigate whether and how governance structure changes in response to the dynamics of the new business environment after the Regulatory Reform Act of 1994 for the US trucking industry. We show that deregulation increases market competition in the trucking industry. The deregulated trucking firms not only adjust internal governance structure but also alter antitakeover provisions to adapt themselves to the competitive status of business environment after deregulation.
