To justify that the Banzhaf index is an appropriate tool to measure the influence of a condition, this paper discusses a novel axiomatization of the Banzhaf index that uses axioms that are directly linked to the QCA methodology.

They fuel political polarization, which is particularly evident in the battleground of social media. Nevertheless, we hardly pay attention to ideologies, their narratives, functions and organizations in economic theory today. Ideologies as “non-rational beliefs” seem incompatible with rationality in economic models. \r\n\r\nTherefore, the book examines the role of ideologies and belief systems in individual decision-making behavior from an economic and rational perspective. Due to the fact that people have incomplete information, belief systems and ideologies fulfill a number of important functions. While ideologies themselves serve psychological needs, they are used as a cognitive framework for rational decision-making once they have been adopted through a Bayesian learning process. They influence decisions in a wide range of areas, from consumption and work to politics. This is where the role of ideological organizations becomes important, because they determine the ideological direction of the narratives and their dissemination. \r\n\r\nThus, ideologies give a normative direction, for better or for worse. The “quality” of ideological leadership can be evaluated normatively on the basis of principles such as individual sovereignty and human dignity. A democratic discourse requires an information and communication system that enables an evaluation of precisely these ideologies, free from resource and information power.\r\n","lang":"eng"}],"status":"public","_id":"60595","department":[{"_id":"19"},{"_id":"202"},{"_id":"475"},{"_id":"200"}],"user_id":"186","ddc":["330"],"language":[{"iso":"eng"}],"alternative_title":["Belief Systems and Ideologies in Rational Decision-making"],"publication_identifier":{"isbn":["9783031935138","9783031935145"],"issn":["2731-5908","2731-5916"]},"publication_status":"published","place":"Cham","year":"2025","citation":{"mla":"Gries, Thomas, et al. <i>The Economics of Ideologies</i>.

But the analytical toolbox of QCA does not include a parameter for the explanatory power of a single explanatory factor or “condition”. In this paper, we therefore reinterpret the Banzhaf power index, originally developed in cooperative game theory, to establish a goodness-of-fit parameter in QCA. The relative Banzhaf index we suggest measures the explanatory power of one condition averaged across all sufficient combinations of conditions. The paper argues that the index is especially informative in three situations that are all salient in international management and call for a context-sensitive analysis of single conditions, namely substantial limited diversity in the data, the emergence of strong INUS conditions in the analysis, and theorizing with contingency factors. The paper derives the properties of the relative Banzhaf index in QCA, demonstrates how the index can be computed easily from a rudimentary truth table, and explores its insights by revisiting selected papers in international management that apply fuzzy-set QCA. It finally suggests a three-step procedure for utilizing the relative Banzhaf index when the causal structure involves both contingency effects and configurational causation.\r\n"}],"type":"journal_article","publication":"Journal of International Management","funded_apc":"1","language":[{"iso":"eng"}],"article_type":"original","keyword":["Qualitative comparative analysis","Banzhaf power index","causality","explanatory power"],"user_id":"20801","department":[{"_id":"205"},{"_id":"475"},{"_id":"178"},{"_id":"185"}],"project":[{"_id":"1","name":"SFB 901: SFB 901","grant_number":"160364472"},{"name":"SFB 901 - A: SFB 901 - Project Area A","_id":"2"},{"grant_number":"160364472","_id":"7","name":"SFB 901 - A3: SFB 901 - Subproject A3"}],"_id":"34114","citation":{"mla":"Haake, Claus-Jochen, and Martin Schneider. “Playing Games with QCA: Measuring the Explanatory Power of Single Conditions with the Banzhaf Index.” <i>Journal of International Management</i>, vol. 30, no. 2, Elsevier, 2024.","bibtex":"@article{Haake_Schneider_2024, title={Playing games with QCA: Measuring the explanatory power of single conditions with the Banzhaf index}, volume={30}, number={2}, journal={Journal of International Management}, publisher={Elsevier}, author={Haake, Claus-Jochen and Schneider, Martin}, year={2024} }","short":"C.-J.

Unlike existing approaches, our anomaly indicator introduces three methodological novelties. First, we use an endogenous, purely data-driven, nonparametric trend identification method to separate long-term market movements from more short-term ones. Second, we apply SETAR models that allow for asymmetric expansions and contractions around the long-term trend and find systematic stock price cycles. Third, we implement these findings in our indicator and conduct real-time market forecasts, which have so far been neglected in the literature. Applications of our indicator using monthly S&P 500 stock data from 1970 to the end of 2022 show that short-term anomalous market movements can be identified in real time up to one year ahead. We predict all major anomalies, including the 1987 Bubble and the initial phase of the Financial Crisis that began in 2007. In total, our anomaly indicator identifies more than 80% of all – even minor – anomalous episodes. Thus, smoothing market exaggerations through early signaling seems possible."}],"status":"public","publication":"Quantitative Finance","type":"journal_article","keyword":["General Economics","Econometrics and Finance","Finance"],"article_type":"original","language":[{"iso":"eng"}],"_id":"50719","department":[{"_id":"19"},{"_id":"200"},{"_id":"202"},{"_id":"475"}],"user_id":"186","year":"2024","page":"1-14","citation":{"ama":"Fritz M, Gries T, Wiechers L.

In Germany, adult vaccination rates are relatively high at 85.5%, but rates are significantly lower for adolescents (69.6%) and children (20.0%). This discrepancy indicates that not all vaccinated parents choose to vaccinate their children. Analyzing data from a January 2022 online survey of 1,819 parents with children and adolescents, we explore the socio-economic factors influencing parents’ willingness to vaccinate themselves and their children. Our results show that individuals who vote for either side of the political extremes are less likely to vaccinate their children. This pattern is particularly strong for voters on the far right. In addition, we find that better educated parents are more likely to vaccinate both themselves and their children. Parents who vaccinate both themselves and their children demonstrate greater confidence in the vaccine’s effectiveness, while those who vaccinate only themselves are often motivated by a desire to regain personal freedoms. These insights highlight the need for targeted public health strategies to address specific concerns and improve vaccination rates among children and adolescents.</jats:p>","lang":"eng"}],"status":"public","publisher":"Springer Science and Business Media LLC","date_updated":"2025-04-04T10:48:45Z","author":[{"last_name":"Hörnig","full_name":"Hörnig, Lukas","first_name":"Lukas"},{"first_name":"Sandra","full_name":"Schaffner, Sandra","last_name":"Schaffner"},{"first_name":"Hendrik","id":"48879","full_name":"Schmitz, Hendrik","last_name":"Schmitz"}],"date_created":"2025-04-04T10:47:50Z","volume":14,"title":"The individual and ecological characteristics of parental COVID-19 vaccination decisions","doi":"10.1038/s41598-024-74963-8","publication_status":"published","publication_identifier":{"issn":["2045-2322"]},"issue":"1","year":"2024","citation":{"ieee":"L.

Moreover, there is large heterogeneity across and within countries. As a whole, Germany has average vaccination rates compared to other industrialized countries. However, vaccination rates in the 16 different German federal states differ by more than 20 percentage points. We describe variation in vaccination rates on the level of the 400 German counties using data on all vaccinations carried out until December 2022. Around 52-72% of that variation can be explained by regional differences in demographic characteristics, housing, education and political party preferences. We find indications that the remaining part may be due to differences in soft factors such as risk aversion, trust in the German government, trust in science, and beliefs in conspiracy theories regarding the origins of the Corona virus. We conclude that improving the trust in science and the fight against conspiracy theories may possibly be effective tools to improve vaccination rates and effectively fight pandemics.</jats:p>"}],"type":"journal_article","publication":"PLOS ONE"},{"title":"Social norms and individual climate protection activities: A survey experiment for Germany","doi":"10.1016/j.eneco.2024.108103","publisher":"Elsevier BV","date_updated":"2025-05-21T10:13:48Z","volume":142,"author":[{"full_name":"Engler, Daniel","last_name":"Engler","first_name":"Daniel"},{"first_name":"Gunnar","last_name":"Gutsche","full_name":"Gutsche, Gunnar","id":"113411"},{"last_name":"Simixhiu","full_name":"Simixhiu, Amantia","first_name":"Amantia"},{"first_name":"Andreas","full_name":"Ziegler, Andreas","last_name":"Ziegler"}],"date_created":"2025-05-21T10:11:41Z","year":"2024","intvolume":"       142","citation":{"ama":"Engler D, Gutsche G, Simixhiu A, Ziegler A.

Ideology is particularly important to conflict. Data on intra- and international conflict shows that the number of ideologically driven conflicts has increased tremendously in recent decades. Although some researchers have started to investigate extensively the link between ideology and conflict, they struggle to find holistic explanations through which ideologies might shape conflict. This book addresses this effort by providing an interrelated multidisciplinary framework to explain the multidimensional functions of ideology. It illustrates that ideologies are not only capable of shaping conflictual behavior or mobilizing political actors, but also of addressing human needs, desires, and preferences. Hence, this book seeks to explain how individuals adopt ideologies that match their underlying needs and preferences; that ideologies have the capacity to reconcile deprived psychological human needs; and that radical groups and organizations use ideologies to recruit individuals and pursue their objectives. To understand these relationships better and to apply the theoretical background to real-world situations, we include real-life cases that describe how depriving individuals of resources that satisfy their underlying needs and preferences can lead them to adopt particular ideologies that are disseminated by radical groups or organizations. These radical groups or organizations then make decisions, which can potentially lead to conflict onset and continuous long-term struggles.</jats:p>","lang":"eng"}],"user_id":"186","department":[{"_id":"19"},{"_id":"200"},{"_id":"202"},{"_id":"475"}],"_id":"54545","alternative_title":["From Human Needs to Intergroup Violence"],"language":[{"iso":"eng"}],"publication_status":"published","publication_identifier":{"isbn":["0197670180","9780197670187","9780197670217"]},"has_accepted_license":"1","citation":{"apa":"Müller, V., &#38; Gries, T.
