Matúš Medo, Manuel Mariani, Linyuan Lü, The simple regularities in the dynamics of online news impact, Journal of Computational Social Science, Vol. 5 (1), 2022. (Journal Article)
Online news can quickly reach and affect millions of people, yet we do not know yet whether there exist potential dynamical regularities that govern their impact on the public. We use data from two major news outlets, BBC and New York Times, where the number of user comments can be used as a proxy of news impact. We find that the impact dynamics of online news articles does not exhibit popularity patterns found in many other social and information systems. In particular, we find that a simple exponential distribution yields a better fit to the empirical news impact distributions than a power-law distribution. This observation is explained by the lack or limited influence of the otherwise omnipresent rich-get-richer mechanism in the analyzed data. The temporal dynamics of the news impact exhibits a universal exponential decay which allows us to collapse individual news trajectories into an elementary single curve. We also show how daily variations of user activity directly influence the dynamics of the article impact. Our findings challenge the universal applicability of popularity dynamics patterns found in other social contexts. |

David Oesch, Felix Urban, The effect of international subsidiaries on voluntary disclosure - evidence from natural disasters, Accounting and Business Research, Vol. 52 (3), 2022. (Journal Article)
This paper documents that managers of multinational companies adjust voluntary disclosure after significant events at international subsidiaries. We show an increase in the likelihood and frequency of management forecasts following natural disasters in regions where companies operate subsidiaries. The exogenous and staggered nature of natural disasters as well as our research design choices substantially raise the hurdle for alternative explanations of our result. Further analyses suggest that the effect is particularly strong for companies that rely on equity financing. Our paper contributes to the nascent literature on transmission effects within international business groups. |

Diethard Klatte, Bernd Kummer, On Hölder calmness of minimizing sets, Optimization, Vol. 71 (4), 2022. (Journal Article)
We present conditions for Hölder calmness and upper Hölder continuity of optimal solution sets to perturbed optimization problems in finite dimensions. Studies on Hölder type stability were a popular subject in variational analysis already in the 1980s and 1990s, and have become a revived interest in the last decade. In this paper, we focus on conditions for Hölder calmness of the argmin mapping in the case of non-isolated minima. We recall known ideas and results in this context for general as well as special parametric programs, refine them and discuss particular settings, including nonlinear programs and convex semi-infinite optimization problems. |

Vrushali Patil, Tarkan Tan, Sonja Rispens, Shaunak Dabadghao, Evangelia Demerouti, Supplier sustainability: A comprehensive review and future research directions, Sustainable Manufacturing and Service Economics, Vol. 1, 2022. (Journal Article)
Sustainability is not a one-player task. Organizations have started to realize that their supply chains have a significant social and environmental impact, usually greater than their own operations, and managing sustainability at suppliers is crucial for supply chain-wide sustainability. Supplier sustainability management (SSM) research is fast evolving across multiple disciplines but lacks an interdisciplinary review to guage the progress made, and to decide the path forward. Heightened global focus on sustainability compels us to explore research avenues in SSM for meaningful progress. In this paper, we provide a comprehensive review of SSM research including the most recent work. We propose the Motivation-Measure-Analyze-Improve-Govern (MMAIG) framework for supplier sustainability, identify the limitations of current SSM research in enabling this framework, and propose future research directions. Our key observations are that (a) current SSM research is heavily focused on measuring and monitoring supplier sustainability, and (b) supplier sustainability improvement/development research is limited and the majority of it is about sustainable supplier selection. The future research directions that we propose are centered around (a) optimizing the investments towards supplier sustainability through collaboration, proposing mechanisms that consider risks, liabilities, and gains of all parties, and (b) considering behavioral aspects to overcome SSM implementation issues. Organizations can achieve efficient improvement in supplier sustainability by using a collaborative approach that is data-driven and trust-based. We discuss several mechanisms within our MMAIG framework that can help organizations in their collaborative approach. |

Dominik van Aaken, Katja Rost, David Seidl, The impact of social class on top managers’ attitudes towards employee downsizing, Long Range Planning, Vol. 55 (2), 2022. (Journal Article)
In this paper, we examine the impact of top managers' social class on their attitude towards employee downsizing. Mobilizing Bourdieu's concepts of social class as a unique social position defined by the combination of economic, cultural, and social capital, we develop hypotheses about the effects of different capital endowments, which we test with unique data on more than 2500 top managers in Germany. We find that both higher economic and higher social capital increase openness towards employee dismissals, while higher cultural capital reduces it. We also find that the overall effect of a top manager's social position is an aggregate of the effects of the individual types of capital: Managers with high cultural, low social and low economic capital are least open to employee dismissals, while those with low cultural, high social and high economic capital are most open – with the other combinations lying somewhere between the two extremes. |

Shauna L Rohner, Florence Bernays, Andreas Maercker, Myriam V Thoma, Salutary mechanisms in the relationship between stress and health: The mediating and moderating roles of Sense of Coherence-Revised, Stress and Health, Vol. 38 (2), 2022. (Journal Article)
While chronic and acute stress are often associated with negative health, the sense of coherence-revised (SOC-R) is proposed to facilitate coping with stress and promote health. However, research is lacking on the specific mechanisms. Therefore, the current study aimed to investigate potential mediating and moderating mechanisms of SOC-R in the relationship between stress and health. Using a cross-sectional design, standardized questionnaires assessed SOC-R, acute (perceived) stress, early-life adversity (ELA; indicator for early-life chronic stress), mental and physical health, and satisfaction with life. Mediation and moderation analyses were conducted with N = 531 Irish adults (mean age: 59.5 years; 58.4% female). Regarding acute (perceived) stress, results showed that SOC-R and its Manageability subscale significantly mediated the association between perceived stress and mental health, and satisfaction with life. SOC-R and its Manageability subscale also significantly moderated the association between perceived stress and mental health. Regarding ELA, the Manageability subscale significantly mediated the association between ELA and mental health, and satisfaction with life; and the Balance subscale significantly mediated the association between ELA and physical health. SOC-R may provide a useful focus for stress-related research, with future longitudinal studies needed to examine SOC-R as a long-term modulating pathway between stress and health. |

Anil Özdemir, Helmut Max Dietl, Gianbattista Rossi, Rob Simmons, Are workers rewarded for inconsistent performance?, Industrial Relations, Vol. 61 (2), 2022. (Journal Article)
This paper examines whether workers are rewarded for inconsistent performance by salary premia. Some earlier research suggests that performance inconsistency leads to salary premia, while other research finds premia for consistent performance. Using detailed salary and performance data for top-level footballers in Italy’s Serie A, we find that inconsistency is penalized for some important dimensions of basic performance measures associated with key skills of players, specifically clearances, aerial duels won, and shots on target. |

Pascal Flurin Meier, Raphael Flepp, Philippe Meier, Egon Franck, Outcome Bias in Self-evaluations: Quasi-experimental Field Evidence of Swiss Driving License Exams, In: UZH Business Working Paper Series, No. 392, 2022. (Working Paper)
Employing a quasi-experimental field setting, we examine whether people are outcome biased when self-evaluating their past decisions. Using data from Swiss driving license exams, we find that candidates who narrowly passed the theoretical driving exam are significantly less likely to pass the subsequent practical driving exam – which is taken several months after the theoretical exam – relative to those who failed narrowly. The candidates who passed the theoretical exam in their first attempt received more objections in momentary, on-the-spot kinds of decisions, consistent with the idea that worse preparation is the underlying behavioral difference. |
