Improving resilience of the healthcare supply chain in a pandemic: Evidence from Europe during the COVID-19 crisis

The severe scarcity of critical medical supplies caused by the COVID-19 pandemic led to considerable procurement challenges in the healthcare supply chain (HCSC). As ensuring the availability of such supplies during disruptions is critical, the debate on how to increase supply chain resilience in healthcare has gained new momentum. We present empirical evidence from a multi-tier case study spanning nine European medical supplies manufacturers and hospital groups. Based on the resource dependence theory, we investigated procurement-related strategies to improve medical supplies availability. We conducted semi-structured interviews with 39 procurement and supply chain management experts and derived seven propositions on buffering and bridging approaches for managing evolving resource dependencies and thereby strengthening supply chain resilience in a pandemic. Overall, we confirm the resource dependence theory's applicability for explaining companies' mitigation measures in a pandemic disruption. We find that bridging measures within the healthcare supply base, such as offering procurement support for suppliers or leveraging long-term buyer-supplier relationships, are more effective for securing medical supplies than buffering measures. Complementing bridging with buffering, such as extended upstream procurement or resource sharing among hospitals, can lead to superior risk mitigation as capacities of the present supplier base may not suffice. Furthermore, we extend the resource dependence theory by showing that the severity of disruptions caused by a pandemic triggers new forms of buffering external to the HCSC. Both traditional and new buffering measures establish novel flows of medical supplies in the HCSC that can enable higher supply security in a pandemic.     

A linear programming model of the urban housing and land markets: Static and dynamic aspects

An extension of the Herbert-Stevens model is presented which incorporates the dynamic aspects of the housing market in order to simulate the filtering process. An open city is assumed with an exogenously given welfare level of the households and constant returns to scale in production. The bid-rent function can thus de defined independently of the resource allocation within the city. The maintenance policy of the landlords is endogenously determined allowing conservation, deterioration, as well as upgrading. Although the model has a normative formulation, the resulting allocation stipulates a competitive equilibrium. The model can be employed to show that discontinuous development can represent an efficient resource allocation.

A differential game in a duopoly with instantaneous incentives

In this paper, we study a differential game in which two competing firms exploit a public renewable resource that is relevant from a landscape point of view. We consider a policy maker that provides an instantaneous incentive to the firms in order to prevent the resource exhaustion during the whole extraction period, which coincides with the harvesting license period. We compute an open-loop Nash equilibrium of the differential game, showing that it coincides with a linear feedback Nash equilibrium. Finally, we compute the value of the incentive that leads to the maximization of social welfare considering the incentive both as a pure transfer and as a cost.     

Measuring HRM effectiveness: Considering multiple stakeholders in a global context

Strategic human resource management research has mostly gravitated towards financial measures of performance in order to assess the effectiveness of human resource management initiatives. In this paper, we argue that focusing on organizational performance mainly from financial stakeholders' perspective is no longer sufficient. We discuss the implications of globalization, changing nature of work and the need to satisfy multiple stakeholders on how we measure the effectiveness of human resource management systems. We provide examples from several reach streams that focus on stakeholders other than shareholders as their main outcome of interest.     

Time is of the essence: Improving the conceptualization and measurement of time

We advance the understanding and measurement of the concept of time by offering a taxonomy of four distinct time constructs: duration, frequency, timing, and sequence. On the basis of a literature review of human resource management and allied fields (i.e., organizational behavior, industrial and organizational psychology, general management, entrepreneurship, and strategic management studies), we offer recommendations on how to measure each construct as well as illustrations drawn from different domains and theories on how these recommendations can be implemented. In addition, for each construct, we offer specific, practical, and actionable recommendations regarding critical design choices, dilemmas, and trade-offs that must be considered when investigating time conceptually and empirically. We discuss these recommendations in the form of a sequential decision-making process that can be used as a roadmap by researchers. We hope our conceptualization and recommendations will serve as a catalyst and useful resource for future conceptual and empirical research that aims to formulate better time-sensitive and temporally falsifiable theories.

Evaluating the operational performance of knowledge-based industries: the perspective of intellectual capital

Performance evaluation is more than a quantitative concept but should also take industrial characteristics into account in order to form an accurate evaluation. In the past, evaluations of the operational performance of knowledge-based industries have missed out a significant factor, which is intellectual capital (IC). By adopting data envelopment analysis (DEA), a multiple-objective decision making method, this study aims to construct an efficiency evaluation model for the Taiwanese digital content industry based on the perspective of IC. The empirical results suggest that the scale of the digital content companies does play an important role in influencing the operating efficiency. The firms have a small amount of capital can still attain optimal efficiency, from the perspective of IC. In addition, human resource capital and customer capital are the most significant influential factors that deserve digital content firms’ attention. It is suggested that enterprises in the digital content industries should focus more on managing their IC. DEA can provide the semiconductor firms’ operations with insights into resource allocation and competitive advantage as well as help with strategic decision-making.     

Human Capital and CEO Compensation during Institutional Transitions

Firms appoint CEOs with different types of human capital in order to manage resource dependencies. How CEOs are compensated thus can be conceptualized as a valuation process of how boards view the value of CEOs' human capital. Two types of human capital – international experience and political ties – have emerged as potential drivers of CEO compensation during institutional transitions. But how they impact CEO compensation has remained unclear. We develop a resource dependence‐based, contingency framework to focus on the external and internal factors that enable or constrain human capital to impact CEO compensation. Because of the tremendous regional diversity within China, externally, we focus on the level of marketization of the region in which firms are headquartered. Internally, we pay attention to two corporate governance mechanisms: politically connected outside directors and compensation committee. Data from 10,329 firm‐year observations at 94 per cent of listed firms in China largely support our framework. Overall, our study contributes to resource dependence research by extending this research to the context of institutional transitions with a focus on how human capital impacts CEO compensation.

Knowledge-oriented human resource configurations,the new product development learning process,and perceived new product performance

We propose a set of organizational efforts that can help companies accumulate and learn knowledge related to new product development (NPD) activities. We call it the NPD learning process and argue that a set of coherent human resource management (HRM) practices, termed knowledge-oriented human resource (HR) configuration, can facilitate the NPD learning process. Collecting survey data from Taiwan, we find that the knowledge-oriented HR configuration is positively related to the NPD learning process and that the NPD learning process is positively related to managers' perceived new product performance. This study contributes to the literature of strategic HRM and innovation management.     

Environmental sustainability orientation,competitive strategy and financial performance

Extant research has established that environmental sustainability orientation (ESO) has a positive influence on performance outcomes. Nevertheless, several contingencies tend to affect the strength of this relationship. In this study, we draw on natural resource‐based theory to introduce competitive strategies as moderators in the ESO–performance nexus. Using time‐lagged data obtained from 269 firms in Ghana, this study finds that firms pursuing the differentiation strategy can positively boost performance outcomes with ESO than without differentiation strategy. We also find that firms can use the low‐cost or the integrated strategy to get higher impact on performance with ESO, respectively. Based on the results, firms in Ghana do not need differentiation strategy in order to boost the effect of ESO on financial performance. Theoretical and practical implications are discussed.     

Contextual factors: assessing their influence on flow or resource efficiency orientations in healthcare lean projects

The outcomes of lean projects have been mixed, with some being successful while many others have not. An explanation for this is a paradox that can develop depending on the focus of the project. Ironically, in projects where the focus is on maximizing the efficiency of a resource (‘resource efficiency’), this focus might lead to worsening of the resource’s efficiency, thereby generating an ‘efficiency paradox’. This paradox does not usually arise in projects where the focus is on the subject of interest being processed through the system in the most efficient manner (‘flow efficiency’). The aim of this paper is to investigate the factors that give rise to either form of efficiency. We conducted a detailed study of eight lean projects in two large hospitals. In doing so, we advance the theory of lean service operations by identifying four key contextual factors that drive the orientation of a project to resource or flow efficiency. These are: service variety, interdependency, capital resource intensity, and service uniqueness. We propose a conceptual framework and four propositions that integrate the contextual factors to determine the dominant focus in lean projects. Through this, recommendations are made as to how the efficiency paradox can be avoided.     

Using human resource management to enhance competitiveness: Lessons from four excellent companies

Recent research has emphasized the strategic focus that human resource management must have in order for an organization to fully utilize its human resources in a competitive market. However, few empirical studies have been done to date regarding how human resource planning should be linked to strategy. An extensive in-depth study of four large, complex, and very successful companies supports the widespread belief that human resource management can be a powerful tool to enhance competitiveness when policies and practices are logically driven by a firm's strategy and by the key environmental factors it faces. This article describes that study and looks at how the areas of selection, appraisal, reward, and development are handled by these firms. Based on both the specific policies and the actual practices as perceived by middle managers (those that implement the policies), the article presents a contingency framework which offers guidelines as to how certain HRM practices should be implemented to gain competitive advantage.     

Seizing the Ethical High Ground: Ethical Reputation Building in Corrupt Environments

We study how ethical behaviour by firms leads to ethical reputation building. Based on our in‐depth studies of two firms in India and Zimbabwe that resisted corruption and survived for extended time periods, we propose that in addition to behaving ethically, firms need to elicit favourable responses from a critical mass of stakeholders from both strong and weak tie networks in order for their ethical reputations to diffuse quickly and widely. We find that the strength of stakeholder responses to ethical behaviour is moderated by firm level and contextual factors: high status affiliations, industry characteristics, the nature of corruption resisted, the presence of a plural press, the potential for collective action, and the presence of an independent judiciary. These antecedents also influence the pattern of stakeholder resource commitments that firms are able to enjoy as a result of having built ethical reputations.

Doing it for themselves? Performance appraisal in project‐based organisations,the role of employees,and challenges to theory

We explore performance appraisal in project‐based organisations and provide novel insights into appraisal processes in this context. These include the central role of employees in orchestrating the appraisal process, the multiple actors that have input to appraisal including project managers, the distance between employees and their official line managers, and the weak coordinating role of human resource specialists in these systems. We draw attention to the drawbacks of current theorising on appraisal to predict and explain outcomes from appraisal systems that are not premised on stable line manager/employee dyads. Theorising based primarily on social exchange theories needs to be reconsidered in this context and new theories developed. We also question how human resource specialists can better support employees, and managers of all kinds, in their implementation roles in polyadic human resource management systems to ensure transparency, equity, and fairness of appraisal processes in a project‐based organisational context.     

Endogenizing the provision of money: Costs of commodity and fiat monies in relation to the value of trade

We consider the problem of including the costs and value of the institutions that define money and support trade, within the framework of economic optimization. We compare monetary systems mediated by durable commodity monies, versus pure fiat monies, in order to understand the separation and eventual independence of the institutionally-created value of money from the values of underlying traded goods. We treat the emergence of monetary function as a problem in mechanism design, modeled by minimal strategic market games that overcome a generalized Jevons failure when agents must commit ahead of time to specialist resource production. We consider in particular the problem of defining closures with respect to both money flows and labor-allocation and trading decisions, and show that minimal models require many of the fundamental institutions of banking and contract enforcement found in real economies, in order to define a self-policing system. We define costs, value, and the efficiencies of the institutions that support trade in terms of a natural money-metric welfare function, and compare the characteristics of commodity and fiat monies by these measures. Through careful treatment of the stock/flow distinction in repeated-game settings, we find that commodity money, even when its value derives heavily from its institutional role, remains defined by its flow characteristics, in contrast to fiat money, for which the control function is defined inherently in terms of stock variables. Our notation is somewhat nonconventional for economics but to do justice to econo-physics concepts such as scaling and dimensional analysis and to stress the distinction between stocks and flows, we believe this notation is justified. We provide a full listing of notation in Appendix A.
