Abstract

Purpose

Academic research has intensively analyzed the relationship between market concentration or market power and banking stability but provides ambiguous results, which are summarized under the concentration-stability/fragility view. We provide empirical evidence that the mixed results are due to the difficulty of identifying reliable variables to measure concentration and market power.

Design/methodology/approach

Using data from 3,943 banks operating in the European Union (EU)-15 between 2013 and 2020, we employ linear regression models on panel data. Banking market concentration is measured by the Herfindahl–Hirschman Index (HHI), and market power is estimated by the product-specific Lerner Indices for the loan and deposit market, respectively.

Findings

Our analysis reveals a significantly stability-decreasing impact of market concentration (HHI) and a significantly stability-increasing effect of market power (Lerner Indices). In addition, we provide evidence for a weak (or even absent) empirical relationship between the (non)structural measures, challenging the validity of the structure-conduct-performance (SCP) paradigm. Our baseline findings remain robust, especially when controlling for a likely reverse causality.

Originality/value

Our results suggest that the HHI may reflect other factors beyond market power that influence banking stability. Thus, banking supervisors and competition authorities should investigate market concentration and market power simultaneously while considering their joint impact on banking stability.

Abstract

Purpose

Heterogeneous and micro-structured materials have been the object of multiscale and homogenization techniques aimed at recognizing the elastic properties of the equivalent continuum. The proposed investigation deals with the mechanical characterization of the heterogeneous material structured metamaterials through analyzing the ultimate strength using the limit analysis of the Representative Volume Element (RVE). To get the desired material strength, a novel finite element formulation based on the derivation of self-equilibrated solutions through the finite elements devoted to calculating the lower bound theorem has been implemented together with the limit analysis in Melàn’s formulation.

Design/methodology/approach

The finite element formulation is based on discrete mapping of Volterra dislocations in the structure using isoparametric representation. Using standard finite element techniques, the linear operator V, which relates the self-equilibrated internal solicitation to displacement-like nodal parameters, has been built through finite element discretization of displacement and strain.

Findings

The proposed work presented an elastic homogenization of the mechanical properties of an elementary cell with a geometry known in the literature, the isotropic truss. The matrix of elastic constants was calculated by subjecting the RVE to numerical load tests, simulated with a commercial FEM calculation code. This step showed the dependence of the isotropy properties, verified with Zener theory, on the density of the RVE. The isotropy condition of the material is only achieved for certain section ratios between body-centered cubic (BCC) and face-centered cubic (FCC), neglecting flexural effects at the nodes. The density that satisfies Zener’s conditions represents the isotropic geomatics of the isotropic truss.

Originality/value

For the isotropic case, the VFEM procedure was used to evaluate the isotropy of the limit domain and was compared with the Mises–Schleicher limit domain. The evaluation of residual ductility and dissipation energy allowed a measurement parameter for the limit anisotropy to be defined. The novelty of the proposal consisted in the formulation of both the linearized and the nonlinear limit locus of the material; hence, it furnished the starting point for further limit analysis of the structures whose elementary volume has been described through the proposed approach.

Abstract

With an increasingly diverse workforce, teams need to handle differences among team members and be aware of the impact these differences have on team meetings. As meetings are strongly shaped by team member interactions, communication between team members is central to meeting success. In diverse teams, effective communication and information sharing is even more crucial than in homogeneous groups due to distinct perspectives and knowledge that group members bring to a team. However, effective communication is also more challenging in groups with diverse members than in homogeneous groups. Especially when there is a strong faultline, that is, when multiple attributes align and teams fall into subgroups, communication within the whole team is impaired and might only take place within subgroups. In this chapter, the authors discuss the role of faultlines in meeting interactions and turn to subgroup formation and its impact on interaction patterns within teams. The authors see intersubgroup communication as an important process that links faultlines to meeting outcomes such as performance or satisfaction. By spanning research areas connecting faultline and meeting research, the authors provide scholars with important research questions to be examined in the future. The authors further introduce a new measure of intersubgroup communication that provides insights into dynamics between subgroups. By relating intersubgroup communication to overall communication within a meeting and taking team size as well as different subgroup constellations into account, this measure facilitates studying intersubgroup communication in meetings. The authors provide formulas that scholars could apply to their research.

Abstract

Purpose

The purpose of this paper is to establish a reference model that will allow us to understand the factors that influence the omnichannel management of an organization in a business-to-business (B2B) context.

Design/methodology/approach

In building the model, a partial least squares structural equation modeling approach was followed. More than 1,000 executives with a C-level profile (chief executive officer, chief marketing officer or chief digital officer), from manufacturers and wholesalers, in various industries worldwide were contacted. The final sample consisted of 124 C-level executives in multinational B2B companies from 35 countries worldwide.

Findings

The principal finding is that optimal omnichannel management must involve a customer-centric proposition forming the basis for individualized marketing that tailors the company’s portfolio of solutions to suit each client. To ensure this, customer knowledge at each touchpoint is essential. The results show that the main predictor of B2B omnichannel management is sales and marketing, even above channels. The principal conclusions are that the model shows that good omnichannel performance is measured by the performance of the industrial buyer. Loyalty and experience are primary measures of this customer’s performance.

Originality/value

Research into omnichannel management in the B2B field is scarce, especially concerning the creation of models for decision-making.

Abstract

Purpose

The purpose of the paper is to propose a homogenization-based topology optimization method to optimize the design of variable-density cellular structure, in order to achieve lightweight design and overcome some of the manufacturability issues in additive manufacturing.

Design/methodology/approach

First, homogenization is performed to capture the effective mechanical properties of cellular structures through the scaling law as a function their relative density. Second, the scaling law is used directly in the topology optimization algorithm to compute the optimal density distribution for the part being optimized. Third, a new technique is presented to reconstruct the computer-aided design (CAD) model of the optimal variable-density cellular structure. The proposed method is validated by comparing the results obtained through homogenized model, full-scale simulation and experimentally testing the optimized parts after being additive manufactured.

Findings

The test examples demonstrate that the homogenization-based method is efficient, accurate and is able to produce manufacturable designs.

Originality/value

The optimized designs in our examples also show significant increase in stiffness and strength when compared to the original designs with identical overall weight.

Abstract

Purpose

To analyze the integration of the circular economy and Industry 4.0 in agtechs through lean integration and people.

Design/methodology/approach

Following in-depth interviews with key informants, data tabulation was performed via families of viewpoints supported by the primary elements mapped in the investigated context.

Findings

The integration of the circular economy with Industry 4.0, and integrated into lean production, aiming to eliminate waste and maximize customer value, and the valorization of people are fundamental in the context of recycling, reuse and reutilization of materials not only in the agricultural sector but also, since it is the object of study of this research. The use of I4.0 technologies and solutions, such as applications, sensors, artificial intelligence and digital platforms, allows for the collection and analysis of real-time data, facilitating decision-making and monitoring of agricultural operations.

Research limitations/implications

The research limitations may include the limited sample of Agtechs analyzed, which might not cover all innovations and trends existing in the sector; data and information available up to the study date (April 2023), which might not reflect more recent developments in the field of Agtechs and the circular economy.

Practical implications

The circular economy seeks to minimize waste and maximize resource use, promoting recycling, reusing and repurposing of materials. In contrast, Industry 4.0 refers to the application of advanced technologies such as artificial intelligence, the internet of things and automation to optimize productive processes and make them more efficient. Lean integration, which aims to eliminate waste and maximize customer value, and the appreciation of people are fundamental in this context.

Social implications

The use of technologies and solutions from Industry 4.0, like apps, sensors, artificial intelligence and digital platforms, allows real-time data collection and analysis, facilitating decision-making and monitoring of agricultural operations. In addition, the provision of online consulting and technical assistance services contributes to producer training and the maximization of results.

Originality/value

Significant benefits for the agricultural sector, such as greater efficiency, sustainability, product quality, traceability, cost reduction and productivity increase. The use of advanced technologies and the valorization of people are key elements to drive this integration and promote digital transformation in the field. The integration of the circular economy and Industry 4.0 in agtechs, integrating lean production and people.

Abstract

Purpose

This study aims to investigate the impact of digital technologies for intangible assets management. The authors analyse how technological innovations and regulations of intellectual property affect business models of companies or intellectual property rights (IPR) intensive industries to determine the impact of digital transformation on intangible assets management, highlighting emerging issues and future effects of the digital technology revolution.

Design/methodology/approach

The authors use a case study method to answer our research questions. The authors use Soundreef SpA as our case study, a collecting company that develops technology for monitoring, collecting and maximising the earnings of songwriters and music publishers. The authors also elaborate and adopt the framework of the enhanced intellectual capital as the theoretical lens for presenting and analysing our case study, determining how the digital transformation caused business model innovation and more transparent and timely performance measurement in copyright-based companies.

Findings

The analysis of Soundreef SpA’s business model allows us to demonstrate how using new technologies drives the performance measurement of copyright holders and improve the collecting societies’ performance, introducing a new key performance indicator. This turning point is made possible by digital transformation and regulatory change. In the IPR industry, copyright holders’ performance has never been calculated, so the distribution of copyright revenues was based on the criteria approved by governance bodies/management.

Originality/value

In the study, the authors demonstrate that digital transformation is able to enhance the intellectual capital of IPR-intensive companies introducing new ways to manage intangible assets and to measure performance.

Abstract

Purpose

While remanufactured products represent an increasingly researched phenomenon in the literature, not much is known about consumers' understanding and acceptance of such products. This study explores this issue in the context of the theory of perceived risk (TPR), investigating return policy leniency and distribution channel choice as potential factors to foster remanufactured products' sales.

Design/methodology/approach

This research utilizes an experimental design composed of a pre-test and a scenario-based main experiment to explore how return policy leniency might mitigate consumers' perceived risk and how their related purchase intention differs across two types of retail distribution channel structures (i.e. brick-and-mortar vs. online).

Findings

The investigation into the efficacy of return policy leniency within two retail distribution channel settings (i.e. brick-and-mortar vs. online) illustrates that providing a lenient return policy is an effective “cue” in increasing consumer purchase intention for remanufactured products. While prior literature has established that consumers value return policy leniency for new products, the authors provide empirical evidence that this preference also applies to remanufactured products. Notably, that return policy preference holds true in both channel settings (i.e. brick-and-mortar vs. online) under consideration. Additionally, and contrary to the authors’ predictions, consumers perceived remanufactured products sold via both channel settings as equally risky, thus highlighting that both are appropriate distribution channels for remanufactured products. Finally, while research on new products provides some initial guidance on consumer perceptions of quality and risk, the study provides empirical evidence into the difference of perceived risk with regard to new versus remanufactured products.

Originality/value

By employing the TPR, this research explored the role played by two supply chain management related factors (returns policy and channel structure) in reducing consumer's perceived risk and increasing purchase intention. In doing so, this study answers the call for more consumer-based supply chain management research in a controlled experimental research setting.
