Supply chain coordination under asymmetric information and partial vertical integration
2022
AbstractSupply chain contracting is known to suffer from inefficiency in the presence of asymmetric information. Full vertical integration would eliminate the informational inefficiency but can be strategically undesirable. Yet today’s supply chain partnerships exhibit a certain degree of partial vertical integration via equity ties between the firms. Such governance forms received limited attention in supply chain research. Management literature suggests that partial vertical integration may help the firms to ease contracting problems by aligning their incentives, and thus improve the total surplus. We address this proposition by studying a model of a partially integrated supply chain in w…
A Mathematical Model for Equitable In-country COVID-19 Vaccine Allocation
2022
Given the scarcity of COVID-19 vaccines, equitable (fair) allocation of limited vaccines across the main administrative units of a country (e.g. municipalities) has been an important concern for public health authorities worldwide. In this study, we address the equitable allocation of the COVID-19 vaccines inside countries by developing a novel, evidence-based mathematical model that accounts for multiple priority groups (e.g. elderly, healthcare workers), multiple vaccine types, and regional characteristics (e.g. storage capacities, infection risk levels). Our research contributes to the literature by developing and validating a model that proposes equitable vaccine allocation alternatives…
Work team effectiveness in organizational contexts
2005
PurposeThis introductory paper aims to provide a contextualization of recent research and applications on work team effectiveness in organizational contexts carried out in Spain and Portugal and to describe connections between this research and the main trends in the international scene.Design/methodology/approachSince the 1990s, new occupational and organizational realities have deepened scientific interest in work teams in both Spain and Portugal. A range of recently published (1992‐2004) works in this area are reviewed. The selected sources are papers published in Spanish, Portuguese and international journals.FindingsReviewing this work, four major trends are identified that synthesize …
Daily deliberative dissonance acting among police officers.
2014
Purpose – The purpose of this paper is to gain insight into the relationships of daily deliberative dissonance acting (DDA) with daily strain and daily work engagement. DDA refers to the deliberate acting of emotions to achieve one's work goals. The authors hypothesized that daily DDA would be positively related to strain through feelings of emotional dissonance. In addition, the authors predicted that DDA would be positively related to daily work engagement via job accomplishment. Design/methodology/approach –The authors applied a five-day quantitative diary design with two measurement occasions per day using a sample of 54 police officers (i.e. 270 measurement occasions). In the multilev…
How BATNAs perception impacts JVs negotiations
2013
PurposeIn light of the inconclusive findings in literature, the aim of this paper is to answer the question: how can negotiation behavior be explained in a situation of power imbalance?Design/methodology/approachBased on Kim et al., the paper proposes a theoretical model that is empirically studied through a case study.FindingsPower relationship is a key contextual factor in determining negotiation behavior in joint ventures (JVs), but it has to be defined more in terms of the perceived value of the alternatives rather than the amount of available better alternatives to a negotiation agreement (BATNAs). Thus, when a partner looks to gain access to knowledge (market, technology, etc.) about …
Exploring relationship variables and Information and Communication Technologies use in industrial segmentation
2017
Purpose In tourism, the adoption of Information and Communication Technologies (hereinafter ICT) and variables concerning firms’ links with suppliers have been recognized as key determinants to improve companies’ competitiveness. From the perspective of efficient management of company resources, segmentation has become a key tool and is particularly significant and current in the business-to-business context. The purpose of this paper is to study the segmentation of firms in the tourist industry according to perceived ICT use and relationship value and benefits. In addition, from the management approach, the authors seek to describe the segments that enable the development of differentiate…
Media constructions of fear in the outbreak of an epidemic disease
2016
Purpose – After almost a decade, the re-appearance of dengue fever in Argentina caused panic and fears. Unlike Bolivia, Brazil and Paraguay, where prevention policies have been followed, the future of dengue is uncertain in Argentina; the present paper does not have political affiliation but the purpose of this paper is to emphasizes the role that mass media plays in the coverage of epidemics. Design/methodology/approach – In moments of disorder, uncertainness or disaster, societies experience a shift in the ways they perceive their reality. Findings – In the times, media plays a dominant role in constructing the reality that the authors get to consume. Such reality is reflective of media’…
An Empirical Research on the Impacts of organisational decisions’ locus, tasks structure rules, knowledge, and IT function’s value on ERP system succ…
2014
This research examined the impacts of organisational decisions’ locus, tasks structure, rules and procedures, organisational actors’ information technology (IT) skills/knowledge and IT department’s or function’s value perceptions on enterprise resource planning (ERP) system success. While such antecedent factors matter in the discourse, research on their impacts on ERP success is rare. To increase understanding in the area, we proposed a research model and developed pertinent hypotheses that included the above-mentioned factors. Using a cross-sectional field survey, we collected data from 165 firms in three European countries. Data analysis was performed using the partial least squares (PLS…
Post-entry internationalisation activity of retailers
2013
Purpose – The purpose of this paper is to propose a framework, based on empirical research, to explain the strategic processes of post-entry development in international retailing through consideration of the dynamic capabilities attributable to retailers. Design/methodology/approach – Case study approach of five international retail firms using secondary data and primary data gathered through interviews with firms ' executives and financial analysts. Findings – The research findings, in the light of the existing literature, suggest a framework that makes a distinction between first level or generic dynamic capabilities relevant to the internationalization process and second level or speci…
A value sensitive ABM of the refugee crisis in The Netherlands
2019
We develop an agent based model to characterize the wellbeing of newcomers (i.e. asylum seeking refugees) in the context of asylum logistics using Schwartz’s theory of values. The model produces recommendations for decision-makers with respect to avoiding catastrophic outcomes and maximizing best case outcomes. We conduct analysis to show that while a relatively simple set of conditions is necessary to avoid catastrophic outcomes, these conditions are insufficient to maximize the best case outcomes. Furthermore, the conditions that maximize one best case outcome do so at the expense of another. The result is a platform for decision-makers to understand tradeoffs in policies for government a…
