Matrix Representation of Solution Concepts in the Graph Model for Conflict Resolution with Probabilistic Preferences and Multiple Decision Makers

Group Decision and Negotiation - In this paper, matrix methods are developed to determine stable states in the graph model for conflict resolution (GMCR) with probabilistic preferences with n...     

Using clustering ensemble to identify banking business models

The business models of banks are often seen as the result of a variety of simultaneously determined managerial choices, such as those regarding the types of activities, funding sources, level of diversification, and size. Moreover, owing to the fuzziness of data and the possibility that some banks may combine features of different business models, the use of hard clustering methods has often led to poorly identified business models. In this paper we propose a framework to deal with these challenges based on an ensemble of three unsupervised clustering methods to identify banking business models: fuzzy c‐means (which allows us to handle fuzzy clustering), self‐organizing maps (which yield intuitive visual representations of the clusters), and partitioning around medoids (which circumvents the presence of data outliers). We set up our analysis in the context of the European banking sector, which has seen its regulators increasingly focused on examining the business models of supervised entities in the aftermath of the twin financial crises. In our empirical application, we find evidence of four distinct banking business models and further distinguish between banks with a clearly defined business model (core banks) and others (non‐core banks), as well as banks with a stable business model over time (persistent banks) and others (non‐persistent banks). Our proposed framework performs well under several robustness checks related with the sample, clustering methods, and variables used.     

Public Sector Organizations and Cocreation With Citizens: A Literature Review on Benefits,Drivers, and Barriers

ABSTRACT

Cocreation has captured the attention of public managers and policymakers and yet the literature focusing in the public sector is still relatively dispersed. In this literature review we present a contextualized analysis of the potential reasons that lead public sector organizations to cocreate with citizens and identify potential barriers that may hamper the adoption of cocreation in public settings. The analysis undertaken allowed us to conclude that the topic is increasingly capturing the interest of researchers, although the state of the literature is characterized by a reduced heterogeneity in research methods. We classified cocreation benefits in the public sector as innovation related, improved decision-making, and symbolic related, and we categorized the drivers for cocreation according to three broad categories: external, relation-specific and internal. Finally, we identified potential barriers of cocreation, including structural, organizational, and behavioral barriers.     

Hybridization: Understanding the microdynamics of a postacquisition integration process

There is no shortage of theoretical or empirical research on mergers and acquisitions (M&A). Knowledge on the subject has grown substantially in recent decades. However, the integration of firms involved in M&A remains a challenging and often unsuccessful process. In addition, there is a scarcity of research on temporal dynamics within integration projects. This article reports on the postacquisition integration of a business school into a university using the concept of organizational hybridization as a theoretical lens. The aim was to identify the microdynamics that occurred during integration. We conducted an inductive case study, interviewing professionals involved in the integration process, analyzing a wide range of documents, and conducting participant observation over 6 years. Field research revealed that different organizational components underwent distinct hybridization processes that were characterized by different degrees of conflict. This study contributes to the understanding of the microdynamics that occur in postmerger or postacquisition integration processes, focusing on the complex adjustments inherent in these developments.     

The "New" Stability and Growth Pact: More Flexible,Less Stupid?

The doubts and criticisms with regard to the fiscal discipline imposed by the Stability and Growth Pact (SGP) have been many and varied, and the SGP was revised as a result. The following paper evaluates the changes contained in the "new" SGP by considering the properties for ideal fiscal rules put forward by Kopits and Symansky. The analysis points towards a clear increase in flexibility together with the probable emergence of new enforcement problems. In this context, the need for new improvements within the European framework for the definition and implementation of national fiscal policies is discussed.     

Does performance explain mutual fund flows in small markets? The case of Portugal

We study the performance reaction of investors in a specific small market context. Our sample includes all Portuguese open-end equity funds that invested in stocks issued by Portuguese companies in the period December 1993–June 2009. Instead of the convex flow–performance relationship usually documented for the US, we find an absence of reaction to past performance. We find no evidence to support the “smart money effect”, given that capital flows do not favour next period performance winners. We also document persistence of fund flows. Our results are consistent with the idea that large financial intermediaries have the capacity “to drive” their customers to funds with larger fees.

Investigating the immediate and long-term effects of job stressors on frontline service employees

Two studies investigate the immediate and long-term effects of job stressors on frontline service employees (FSEs). Using cognitive appraisal theory, we develop and test a conceptual model of two job stressors (crowding and emotional labor) that affect coping strategies and job outcomes. Study 1, which is a field experiment, investigates the immediate effects of crowding in a single firm. Study 2 extends the findings of Study 1 and investigates the long-term effects of emotional labor and crowding on FSEs across multiple firms. The results show that crowding has a negative impact on coping strategies and job-related outcomes. In addition, emotional labor can lead to long-term negative outcomes, such as emotional exhaustion and decreased job retention, for some FSEs. Consequently, service organizations should consider strategies or tactics that prevent high levels of customer crowding and help FSEs deal with emotional labor.     

The relationships between food-related personality traits,satisfaction, and loyalty among visitors attending food events and festivals

This study applies the concept of food-related personality traits to hospitality and tourism and identifies relationships between personality, satisfaction, and loyalty. An on-site survey was carried out with 335 visitors attending the Gwangju Kimchi (local food) Festival in South Korea between 15th and 19th of October, 2008. The relationships between 4 latent constructs (food neophobia, food involvement satisfaction, and loyalty) and 16 indicators were measured using structural equation modelling. The findings showed that food neophobia had a negative effect on satisfaction and loyalty, food involvement had a positive relationship with loyalty, and satisfaction and loyalty showed a significant positive relationship.
