Abstract

Phosphonic acids are good complexing agents. However, they are not good as inhibitors except for a very few. Synergistic inhibition is offered in the presence of metal cations like Ca2+, Mg2+, Zn2+ and others in neutral media. The zinc ion is an ideal choice. The part of zinc ions are now replaced by polymers, azoles to prepare eco‐friendly inhibitor formulations. They are also used as corrosion inhibitors in concrete, coatings, rubber blends, acid cleaners, anti‐freeze coolants, etc. Discusses the various applications of phosphonic acids and their action mechanisms.

Abstract

Purpose

This study aims to address the lack of discrimination between fully efficient decision-making units in nonparametric efficiency analysis models by introducing a new ranking technique that incorporates contextual variables.

Design/methodology/approach

The proposed method combines Data Envelopment Analysis (DEA) and Ordinary Least Squares (OLS). First, DEA evaluates the partial efficiency of each unit, considering all inputs and only one output. Next, OLS removes the influence of contextual variables on the partial efficiencies. Finally, a ranking criterion based on modified partial efficiencies is formulated. The method is applied to data from 100 Chinese banks, including state-owned, commercial and industrial institutions, for the year 2020.

Findings

The ranking results show that the top six positions are assigned to highly esteemed banks in China, demonstrating strong alignment with real-world performance. The method provides a comprehensive ranking of all units, including nonextreme efficient ones, without excluding any. It resolves infeasibility issues that arise during the ranking of efficient units and ensures uniqueness in efficiency scores, leading to a more reliable and robust ranking process. Contextual variables exerted a greater influence on the first partial efficiency compared to the second. Notably, Total Capital Adequacy (TCA) significantly impact bank efficiency.

Originality/value

This study introduces a novel ranking method that effectively integrates contextual variables into DEA-based efficiency analysis, addressing limitations of existing methods. The practical application to Chinese banks demonstrates its utility and relevance.

Abstract

Purpose

The purpose of this paper is to empirically study the impact of product patent regime on the productivity of different categories such as ownership, R&D, size and product-wise of Indian pharmaceutical firms using non-parametric data envelopment analysis.

Design/methodology/approach

The present study has applied Ray and Desli’s Malmquist productivity index and its decomposition to measure total factor productivity (TFP) change, pure technical efficiency change, scale efficiency change and technical change under variable returns to scale (VRS) technology assumption for 141 Indian pharmaceutical firms during 2000-2001 to 2014-2015.

Findings

The study found the negligible impact of product patent regime on productivity. The technological change has played a positive role in the growth of productivity, whereas technical efficiency change depicts the judicious utilization of resources for improving performance. From the results, it is found that R&D intensive firms depict better stability in the TFP than the non-R&D firms. However, Granger causality between R&D and productivity found no relationship. Productivity is more directly affected by investment in fixed assets rather than in R&D, which focusses on incremental value additions in a largely branded/plain generic product market. In case of ownership, private foreign firms found to have registered progress in TFP while others have recorded marginal regress, which probably could be attributed to the superior marketing and management skills of the foreign firms, besides possessing proprietary technology. Both small and large firms have shown positive growth in the new regime as compared to the pre-patent regime. These small firms are able to compete with large firms because of their up-gradation of the technological base by improving access to better foreign technology. TFP growth for all the firms can be attributed to improvement in technology, and innovation in terms of high capital-output ratio. Further, the paper tried to identify the determinants of productivity from panel random effect regression, and it is found that export intensity, age and the new patent regime have negative and significant relationship with productivity, whereas other variables such as R&D, ownership, size and capital imports are insignificant. In the end, the results of sensitivity analysis have confirmed the validity of the selected variables.

Practical implications

The results suggest that Indian pharmaceutical firms need substantive improvement in TFP by improving managerial and scale efficiency. Indian pharmaceutical industry (IPI) needs to improve productivity across the network and drive cost excellence initiatives across the spend base through operational excellence and digital initiatives. The results of this paper can be applied in framing policies for future growth and improvement in the productivity of IPI.

Originality/value

The paper aims to make several new contributions to the existing literature. Most of the research papers only analysed TFP of the industry as a whole and detailed firm-wise analysis is needed to capture the true impact at a unit level. This study has analysed the impact of different categories such as ownership, R&D, size and product-wise, and determinants of productivity. The study has used a broader time period and larger panel data to predict the better picture.

Abstract

Purpose

The purpose of this study is twofold. First, this research estimates banks' efficiencies from the perspectives of resource utilization and investment after incorporating risk measures as an exogenous input in the investment-efficiency stage. Second, the current study examines the relationship between intellectual capital (IC) and banks' efficiencies.

Design/methodology/approach

First, this study uses a dynamic network data envelopment analysis approach in investigating the efficiencies of 24 Taiwanese banks in 2007–2018 from two perspectives. Second, this research utilizes various regression techniques, namely, ordinary least squares (OLS), robust least squares and truncated regression, to gauge the impact of IC on banks' efficiencies. Typically, IC is determined based on a monetary value-based measure and value-added intellectual coefficient (VAICTM).

Findings

Resource-utilization (investment) efficiencies were observed as 0.941 (0.964), thereby contributing to the mean overall efficiency of the sample banks at 0.952. However, the related efficiency changes decline over the sample period, thereby suggesting that the average banks' efficiencies hardly increase. Regression analyses show a significantly positive relationship between IC and banks' overall resource-utilization and investment efficiencies.

Research limitations/implications

Overall, this study suggests that researchers should consider risks when estimating banks' efficiencies owing to their connection to banks' investment performance. From banks' dynamic two-stage efficiencies, this study demonstrated that investments in IC will bring improved future economic benefits.

Originality/value

Different from prior studies, this study improves banks' efficiency evaluation models by incorporating risk measures and assuming weighted periods for the 2007–2008 global financial crisis. Moreover, the use of monetary value-based measure of IC provides consistent results as the commonly-used VAICTM does.

The goal of this paper is to develop a model which may be used to demonstrate costs and benefits of risk management investments in the context of value-based management.

Abstract

Purpose

The goal of this paper is to develop a model which may be used to demonstrate costs and benefits of risk management investments in the context of value-based management.

Approach

This paper answers the question of how to quantify changes in company value caused by risk management measures on a theoretical basis. First, a review of empirical studies allowing assertions about the cost and utility of risk management investments is presented. The results of these studies point to a nonlinear shape of the curve and form a basis for the development of a seemingly plausible cost/utility correlation.

Findings

In this paper, a model will be developed which can be used to demonstrate costs and benefits of risk management investments in the context of value-based management. It is assumed that at first, risk management expenditures without measurable monetary utility will have to be made. Furthermore, it is assumed to increase more than proportionally, then less than proportionally, until further investments in risk management activities yield only minimal increases in utility and cannot improve company value any further.

Practical implications

By inserting the yet-to-be-determined actual cost/benefit relationship for a company or industry sector into the EVA equation, it is possible to display the effects of risk management measures on the company value. This procedure is principally combinable with the analysis of other value-based control parameters, that is, the Discounted Cash Flow concept or the Cash Value Added methodology.

Originality

Risk management is increasingly gaining scientific and public interest, especially since the global financial crisis. Scientists and practical users espouse the benefits of risk management systems in this context. However, the extent to which investments in risk management systems can improve the value of a company remains still unclear.

We could determine that at first risk management expenditures will not result in a monetarily measurable benefit. The remaining slope of the curve is derived as increasing more than proportionally at first, then less than proportionally, until further investments into risk management activities yield almost no additional increase in benefits. In this paper, three different functions are offered to describe the shape of the curve identified. They differ in regard to their free parameters and hence in their flexibility of application. The higher flexibility of functions #2 and #3 is balanced by the disadvantage of increasing formal complexity, possibly leading to an increased effort for implementation and application.

Research limitations

To harness the relationships developed in this paper for practical use, further research should target the identification and empirical verification of dependencies between the parameters and principal company index values.

Abstract

Purpose – The purpose of this study is to investigate whether a firm’s cost structure (specifically, its cost stickiness) is associated with environmental, social, and governance (ESG) sustainability factors of performance and disclosure.

Methodology/approach – This study uses MCSI Research KLD Stats (KLD) and Bloomberg databases for the 13-year period from 2003 to 2015 in constructing ESG performance and disclosure variables, respectively. The authors adopt the general cost stickiness models from Anderson, Banker, and Janakiraman (2003) and Banker, Basu, Byzalov, and Chen (2016) to perform the analysis.

Findings – The authors find that a firm’s level of cost stickiness is positively associated with certain sticky corporate social responsibility (CSR)/ESG activities (both overall and when separately classified as strengths or concerns) but not with other nonsticky CSR activities. The authors also show that the association between cost stickiness and ESG disclosure is incrementally stronger for firms with CSR activities classified as sticky. Furthermore, the authors provide evidence that ESG disclosure is greater when both cost stickiness and the degree of sticky CSR activities increase. The authors show that when cost stickiness is high and CSR activities are sticky, management has incentives to increase CSR/ESG sustainability disclosure to decrease information asymmetry.

Originality/value – The findings present new evidence to understand how management integrates cost management strategies with various dimensions of sustainability performance decisions and show that not all ESG activities are equally effective when it comes to cost stickiness. The authors also demonstrate that increased sustainability disclosure helps reduce information asymmetry incrementally more when both costs are sticky and CSR activities are sticky.

Abstract

Purpose

This paper aims to examine how compensation committees perceive audit quality as indicated by audit firm tenure. Using the contracting weight attached to earnings and cash flows in chief executive officer (CEO) compensation as proxy for the compensation committee’s perception of audit quality, the study examines whether compensation committees perceive performance metric informativeness as being affected by auditor tenure.

Design/methodology/approach

The paper regresses CEO cash compensation on accounting-based performance metrics and on interactions between auditor tenure and accounting-based performance metrics while controlling for other factors previously shown to affect CEO pay. Auditor tenure is measured using continuous and dichotomous variables.

Findings

Auditor tenure is associated with a reduced (positive) weight on earnings (operating cash flows), which suggests lower perceived audit quality as tenure lengthens consistent with the auditor closeness argument. This relation is asymmetric, i.e. the negative effect of longer auditor tenure on incentive contracting is more pronounced for positive earnings. The results are robust to using CEO total compensation as the compensation measure, as well as using level and change specifications.

Research limitations/implications

The inability to control for audit partner tenure in assessing the effect of audit firm tenure on incentive contracting and the potential endogeneity between auditor tenure choice and incentive contracting are the main limitations of this study. Given the lack of information on US audit partner tenure, the study could not control for the audit partner tenure issue. However, the study has attempted to mitigate the endogeneity issue by using a Heckman selection model that includes in the first-stage a regression of auditor tenure on various firm, performance measure and CEO-related governance characteristics, based on existing models (Li et al., 2010).

Practical implications

Compensation committees view auditor tenure as an indicator of accounting quality in setting CEO pay. Further, long auditor tenure is perceived as detrimental to financial reporting integrity, particularly when earnings numbers suggest positive managerial performance and innovations.

Originality/value

This study provides empirical evidence that auditor tenure matters in setting executive pay. Further, this study shows evidence on the link between auditor tenure and audit quality from an internal user’s perspective. Prior studies have focused either on external users (investors, creditors) or on the preparer (using measures such as discretionary accruals or meet/beat analysts’ forecasts or forecast guidance).

Abstract

Purpose

This paper is an empirical study of outsourcing practices in the banking sector in India. The purpose of the paper is to investigate the impact of factors which influence the decision makers' attitude towards outsourcing.

Design/methodology/approach

Based on a review of the existing literature, an attitudinal model of outsourcing was developed. This model was used to: identify the key factors of benefits, risks, roadblocks, and criticality of outsourcing; develop the instrument to measure the factors; and formulate hypotheses concerning the impact of these factors. The constructs in the instrument that measured these factors were validated by factor analysis.

Findings

The impacts of perceived benefits, perceived roadblocks, and perceived criticality on the attitudes towards outsourcing were found to be strong and statistically significant. The impact of perceived risk was weak and statistically insignificant. The model explaining the combined impact of these four factors on outsourcing attitudes was also statistically significant.

Research limitations/implications

An important insight from this study is that the clients, at least in the banking sector in India, tend to value in outsourcing quality factors such as process improvement, services improvement and cost transparency more than cost savings. The results of the study provide a basis for rethinking the value proposition offered by outsourcing vendors and for refocusing the research on outsourcing of services in particular.

Originality/value

While most studies on outsourcing tend to be theoretical and/or focus on outsourcing from developed to developing countries, this is an empirical study focusing on outsourcing by organizations based in developing countries such as India. Therefore, the results are not confounded by differences in culture‐specific communications, business practices, and regulatory regimes between the countries.

Abstract

Purpose

The purpose of this paper is to determine the most efficient hotels in the Indian hotel industry, the competitive positioning of these hotels, and the factors that affect their efficiency change.

Design/methodology/approach

This study conducts a two-stage analysis and uses data envelopment analysis (DEA) and Global Malmquist productivity index (MPI) approach in the first stage to calculate the managerial performance of a panel of 63 Indian hotels in 2019–2020 and their efficiency change from 2009–2010 to 2019–2020. Bootstrapped generalized least square (GLS) approach is applied in the second stage to evaluate the impact of contextual variables on efficiency change.

Findings

Using the results of the first stage analysis, the authors categorized the 63 Indian hotels into 7 distinct clusters. These clusters represent different levels of competitiveness and pace of growth. The GLS regression reveals a U-shaped relationship between hotel size and efficiency change and a negative relationship between pro social investments and efficiency.

Originality/value

This is the first study in the hotel industry that has used global MPI as a measure of efficiency change in the first stage and GLS in the second stage. In the Indian context, to the best of authors’ knowledge, no such study exists.
