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. 相似文献

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. 相似文献

We consider an industry composed of a multiproduct corporation that adopts corporate social responsibility (CSR) as a strategic managerial delegation and examine the profit-incentive to form a cooperative group. We find that competition is an equilibrium for any degree of substitutability and yields the highest CSR, which is increasing in the degree of substitutability. We also show that full cooperation is an equilibrium for lower substitutability but induces no CSR, whereas partial cooperation with one uniplant firm is an equilibrium for higher substitutability but yields lower CSR than that under competition. Therefore, cooperation might reduce strategic CSR activities, whereas competition will encourage higher CSR but yield lower industry profits. 相似文献

We estimate the effect that star students have on their siblings’ learning outcomes, measured by their high school grade point average (GPA) and their math grades. To this end, we couple administrative school data on grades with an unusual natural experiment in Peru that generates exogenous variation in the presence of star students at home. We find that star students increase their siblings’ GPA by 0.33 SDs and their math grades by 0.22 SDs. The effect size is inversely related to number of siblings, suggesting that the remaining siblings act as substitutes for the star student. 相似文献

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. 相似文献

Microfinance targets women and uses loan provision as a tool for empowerment, which translates into better household nutrition, improved education, and a scale down of domestic violence. However, ethnic discrimination in microfinance may exist in countries with a segregated indigenous population. We assessed this possibility with a field experiment in Bolivia. The controlled laboratory experiment evaluated whether credit officers rejected microloan applications based on the interaction effect of ethnicity and gender of potential borrowers. Point estimates of a Bayesian mixed‐effects logistic regression, estimated with the experimental data, indicate that nonindigenous women have double the chance of loan approval, but indigenous women have only 1.5 times the chance of loan approval when compared with men. While the findings about gender are limited, the evidence for the interaction of gender and ethnicity is more robust and suggests the existence of positive taste‐based discrimination favorable for nonethnic women in Bolivia. We conclude that the affirmative actions towards women promoted by development agencies and microfinance institutions must not overlook ethnicity as an important factor for financial policies of sustainable development. In practice, these policies should be aimed at identifying and reducing both social desirability bias and the structural barriers to financial inclusion that indigenous women may face when trying to obtain access to a loan. 相似文献

In this paper, we use firm-level data on the universe of Italian manufacturing multi-product exporters to test whether demand shocks in export markets lead multi-product exporters to increase their productivity. The main mechanism behind the documented productivity gains is the reallocation of resources across products within firms (American Economic Review, 104, 2014 and 495; National Bureau of Economic Research Working Paper Series No. 22433, 2016). Intuitively, the increased demand stemming from foreign markets will induce firms to adjust their product mix by moving inputs from low to high productive/profitable uses. We find that these productivity gains are significant and can explain between 1/10 and 1/2 of aggregate productivity growth in the manufacturing sector. 相似文献

This research explores the role of advanced information technologies at the ‘fuzzy’ front-end of service innovation and design. Service researchers have been exploring the application of technology to services for a while, however there has been little attention paid to the use of technology at the front-end of service innovation and design. Research suggests that advanced information technologies should be useful in research and development for services; but how this may occur has not been explored. Bringing together design thinking and the technology–organization–environment framework for technology adoption this research develops propositions for research to expose how technology can advance and transform service innovation and design. Theoretical and practical research questions are offered to guide inquiry in this emerging research space. 相似文献

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. 相似文献
