Abstract

Purpose

The purpose of this paper is to investigate the quality determinants influencing the adoption of e-government services in Oman and compare the performance of multiple regression and neural network models in identifying the significant factors influencing adoption in Oman.

Design/methodology/approach

Primary data concerning service quality determinants and demographic variables were collected using a structured questionnaire survey. The variables selected in the design of the questionnaire were based on an extensive literature review. Factor analysis, multiple linear regression and neural network models were employed to analyze data.

Findings

The study found that quality determinants: responsiveness, security, efficiency and reliability are statistically significant predictors of adoption. The neural network model performed better than the regression model in the prediction of e-government services’ adoption and was able to characterize the non-linear relationship of the aforementioned predictors with the adoption of e-government services. Further, the neural network model was able to identify demographic variables as significant predictors.

Practical implications

This study highlights the importance of service quality in the adoption of e-government services and suggests that an enhanced focus and investment on improving quality of the design and delivery of e-government services can have a positive impact on the usage of the services, thereby enabling the Oman Government in achieving the governance objectives for which these technologies were employed.

Originality/value

Studies in the area of e-government typically focus either on technology adoption problems or service quality problems. The role of service quality in adoption is rarely addressed. The research presented in this paper is of great value to the institutions that are involved in the development of technology-based e-government services in Oman.

Abstract

Purpose

The purpose of this paper is to analyze the performances of the insurance sector in Gulf Cooperation Council (GCC) countries and carry out a comparative analysis for its different units.

Design/methodology/approach

The authors analyse the technical efficiency of insurances in the GCC countries using DEA methodology and Malmquist Productivity Index (MPI) to decompose the change in the efficiency into an intrinsic component reflecting the individual change in technical efficiency and a second component reflecting the impact of the change in the market technology on the individual technical efficiencies of insurance companies.

Findings

The study considers 39 insurance firms in the region, with a panel data covering the period 2005‐2007. The authors found that the insurance industry in the GCC is moderately efficient and there is large room for improvement.

Originality/value

In these very special market conditions, a deep analysis of the overall efficiency of the sector is needed and an assessment of its performance – to the authors' best knowledge so far non‐existent – becomes a must to provide insights about the realities and the future trends of the sector. This research uses DEA and MPI to assess the efficiency of the insurance sector in the GCC region and analyses its variation over the period 2005 to 2007.

Abstract

Purpose

Merger and acquisition (M&A) plays an important role in developing the financial sector. The purpose of the paper is to analyze and evaluate the effects of M&As on the outcome of Islamic and conventional banks. Furthermore, examines the mediating role of market structure between M&A and bank outcome.

Design/methodology/approach

This paper uses POLS, panel data techniques and structural equation modeling to analyze a set of samples for 24 banks consisting of 10 Islamic banks and 14 conventional banks involved in M&A from 2004Q1 to 2020Q4 from 6 countries.

Findings

Generally, M&A improves the post-M&A performance of Islamic banks and conventional banks. However, there is size issue. Bank size positively affects Islamic bank performance while conventional does not. Furthermore, market structure mediates the relationship between M&A and the operational performance of Islamic and conventional banks. Implying that after M&A, the market becomes concentrated while it reduces competition.

Research limitations/implications

Number of banks are limited due to unavailability of data for pre and post-M&A. Future researches can be carried out to study the cross-border M&A along with the regulation between Islamic banks in GCC and Asia Pacific countries.

Practical implications

Improving operational performance plays a significant role. To enhance the performance of Islamic banking industry, M&A between small Islamic banks could be beneficial depending on the market structure.

Originality/value

The mediation role of market structure in between M&A and performance for Islamic and conventional banks is the main contribution of the study.

Abstract

Purpose

The purpose of this paper is to assess the efficiency determinants of mergers and acquisitions (M&A) in the context of Latin American airlines based on business-related variables commonly found in the literature. The idea is to identify preferable potential airline matches in light of fleet mix, ownership structure and geographical proximity.

Design/methodology/approach

In order to achieve the objective, all possible combinations of M&A pairs are considered in the analysis, which is developed in a two-stage approach. First, the M&A Data Envelopment Analysis model efficiency and returns-to-scale estimates are computed. Then, robust regression and multinomial logistic regression are respectively used to discriminate these estimates in terms of such business-related variables.

Findings

The results reveal that these different contextual variables significantly impact virtual efficiency and returns-to-scale levels. Private ownership, passenger focus and a better match between aircraft size and demand for flights appear to be key drivers for merged airline efficiency.

Research limitations/implications

The study makes theoretical contributions, though limited to analyzing Latin American airlines only. The use of bootstrapped robust/multinominal logistic regression, compared to the methods adopted by previous literature studies, generates more accurate and robust results related to the efficiency drivers due to its special feature and ability to allow the discrimination of increasing, decreasing, and constant returns to scale in light of a given set of contextual variables.

Practical implications

This study examines the pure effect of the merging activity on efficiency gains. Not only private ownership but also a hybrid public–private ownership has a positive influence on virtual efficiency, suggesting an important governmental role in promoting M&A in the airline industry.

Originality/value

The authors present an original take on the issue of airline mergers by exploring what are the major drivers possibly involved in efficiency gains of potentially merged (virtual) airlines. The authors identify preferable potential airline matches where efficiency gains would be positive in light of business-related variables such as fleet mix, ownership structure and geographical proximity. The analysis also includes an assessment of the impact of contextual variables such as cargo type, ownership structure and geographical proximity in relation to the strategic fit of mergers considering the resulting efficiency and returns-to-scale scores of virtually merged airlines. To the authors’ knowledge, no previous research has addressed these issues in Latin American airlines. Further research directions for this industry are also discussed.

Abstract

Purpose

This paper aims to discuss and collect evidence about the hypothesis that, under imperfect information, the multipurpose public organization emulates its peers, arguing that this hypothesis can be fruitful to the study of this kind of organization.

Design/methodology/approach

At IPEC – Instituto de Pesquisa Clínica Evandro Chagas, the clinical research institute affiliated to FIOCRUZ – Fundação Oswaldo Cruz, activities relating to infectious diseases –, e.g. diagnostic exams; outpatient care and patient admissions; teaching and research – are structured in the form of integrated action programs (briefly, PAIs). Taking into account the complexity of this organizational format, this paper applies a mathematical model allowing to define and compute managerial indicators referring to the eight main PAI programs with a view to measure their performance, to investigate whether there are any scale inefficiencies in the eight programs selected as decision‐making units (DMUs) and to assess the effectiveness of the whole organizational structure. To accomplish those objectives, the paper employs the so‐called DEA models with variable returns to scale – whereby two input and seven output variables were used to represent the eight DMUs.

Findings

Findings suggest that PAIs related to clinical research operated under increasing returns to scale between 2002 and 2006. To that extent, both the choice of PAIs as an organizational format and the current growth strategy at the Institute may be considered adequate.

Originality/value

This approach is valuable to complement the cost minimization analysis of specific activities of multipurpose organizations and has general application to the overall assessment of performance, structures and strategies in these organizations.

Abstract

Globalization speeds up competition among nations in various sectors. In terms of multinational and transnational phenomena, countries are seen as inescapable from competition, thus the linking of the term global with “competitiveness.” The research described here explores the relationship between the competitiveness of a country and its implications for human development. For this purpose, using data envelopment analysis (DEA) and cluster analysis, 44 selected countries were evaluated. An output-oriented super-efficiency model where global competitiveness indicators are taken as input variables with human development indicators as output variables is utilized. Then cluster analysis depending on the competitiveness and human development indicators is conducted by using self-organizing maps to specify the development levels of the countries. Both analyses are repeated for years between 2005 and 2007. Finally, the relationship between the super efficiency scores and the development levels is analyzed.

Abstract

A great deal of uncertainty accompanies predictions of the potential effects of global climate change on the coastal hazards associated with severe storms. One way to obviate the effects of this uncertainty on the design of policies is to understand the manner in which populations are currently vulnerable to these types of hazards. In this chapter, we develop a method for constructing a relative composite measure of vulnerability using data envelopment analysis (DEA). Through the application of this index, and one constructed using a weighted average, to four costal towns along Boston's North Shore, we demonstrate their potential usefulness to policy formulation and implementation. The DEA composite index is shown to complement the information provided by the weighted average and helps overcome some of its shortcomings such as assigning importance weights and masking of the influence of one or a subset of vulnerability attributes. Acknowledging the spatial implications of floodplain protection and mitigation efforts, the indices are constructed and analyzed at a number of different geographic scales.

Abstract

Purpose

The purpose of this paper is to investigate the voluntary horizontal M&A impact on operating performance in Nigeria between 1995 and 2012 under different complementary approaches.

Design/methodology/approach

Residual income valuation (RIV), economic value-added (EVA), data envelopment analysis (DEA) and stochastic frontier analysis (SFA).

Findings

Results showed a statistically significant improvement in the technical efficiency of both bidder and target companies, the reduced efficiency levels of the bidder firms under DEA scores reveals the specifics of the productive technology. This may suggest that resulting merged companies in Nigeria may have not even become too big in scale or even reached the most productive scale size, despite their almost monopolistic position in the sector. This happens because the scale size of the sector is small per se, implying that the investments necessary to achieve synergistic gains have to be partially covered by price increases.

Practical implications

This study will guide both the M&A practitioners, investment banks, and the policy makes. In terms of having to review M&A policy as well as seeing to the improvement in the infrastructural needs.

Social implications

With improved performance, employment can be created thereby giving employment to the youths. This will reduce social problems.

Originality/value

From the literature and records, no long-term operating performance on voluntary mergers and acquisitions has not been carried out in Nigeria. The paper seeks to know the fundamental value of the firms after these transactions with the current methodology that is acceptable from the literature.

Abstract

Purpose

The purpose of this paper is to present a productivity measure for hospital services in Ontario.

Design/methodology/approach

The study applied the Malmquist Productivity Index (MPI) to assess the efficiency of hospital services in Ontario, Canada, over the period 2003‐2006. The MPI was decomposed into efficiency change and technological change. Efficiency change was further decomposed into pure efficiency change and scale efficiency change. A bootstrapping technique was also used to obtain confidence intervals for the output oriented MPI and its decompositions.

Findings

By estimating confidence intervals it was found that a large number of hospitals did not achieve significant progress in terms of productivity. By taking geometric means of estimates for all years it was observed that while overall productivity and efficiency of hospitals in Ontario declined during the study period, technological progress increased at a rate of 5.95 percent on average.

Practical implications

The present study helps to understand the productivity and technological change and change in technical efficiency in this vital sector of the economy, which is important for policy making identifying improvement opportunities in resource allocation. It was observed that Ontario hospitals did not improve the efficiency with which they employed their inputs (i.e. staff and supplies) over the study period; they did achieve gains through application of technologies.

Originality/value

The paper provides a thorough study on productivity growth of health care services in Ontario using a non‐parametric framework with bootstrapping. It also provides a robust measurement and analysis of the contributions of technology, size of operation and use of inputs to the performance of hospitals in Ontario.

Abstract

Purpose

This study aims to examine in depth the impact of merger activities on banks in Saudi Arabia.

Design/methodology/approach

Event study, financial ratio and efficient frontier analyses with a mixture of parametric and non-parametric tests are used for the sample period 2016Q1–2022Q4.

Findings

Event study analysis shows that merging banks (bidders) have higher positive cumulative abnormal returns than merged banks (targets), indicating that investors believe that bidding banks will benefit the most from the merger strategy. It was also found that the efficiency measures of the combined banks of Saudi British Bank and Alawwal Bank deteriorated, while they improved for the combined banks of National Commercial Bank and Saudi American Bank in the post-merger period, confirming investors' views.

Research limitations/implications

Although the study focuses on the Saudi banking sector, its findings could be generalized to other banks in the region, as the Saudi banking sector is one of the largest in the Middle East region and is expected to grow further in the future.

Practical implications

The mere act of merging two banks does not guarantee the realization of cost synergies or efficiency gains. This research shows that mergers are not automatically cost-effective and that their success depends on good integration and restructuring strategies.

Originality/value

To the best of the author's knowledge, this is the first study to provide a comprehensive analysis of the short- and long-term impacts of merger activities in the Saudi banking sector.
