@article{34114, abstract = {{Qualitative comparative analysis (QCA) enables researchers in international management to better understand how the impact of a single explanatory factor depends on the context of other factors. 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. }}, author = {{Haake, Claus-Jochen and Schneider, Martin}}, journal = {{Journal of International Management}}, keywords = {{Qualitative comparative analysis, Banzhaf power index, causality, explanatory power}}, publisher = {{Elsevier}}, title = {{{Playing games with QCA: Measuring the explanatory power of single conditions with the Banzhaf index}}}, year = {{2023}}, } @techreport{32106, abstract = {{We study the consequences of modeling asymmetric bargaining power in two-person bargaining problems. Comparing application of an asymmetric version of a bargaining solution to an upfront modification of the disagreement point, the resulting distortion crucially depends on the bargaining solution concept. While for the Kalai-Smorodinsky solution weaker players benefit from modifying the disagreement point, the situation is reversed for the Nash bargaining solution. There, weaker players are better off in the asymmetric bargaining solution. When comparing application of the asymmetric versions of the Nash and the Kalai-Smorodinsky solutions, we demonstrate that there is an upper bound for the weight of a player, so that she is better off with the Nash bargaining solution. This threshold is ultimately determined by the relative utilitarian bargaining solution. From a mechanism design perspective, our results provide valuable information for a social planner, when implementing a bargaining solution for unequally powerful players.}}, author = {{Haake, Claus-Jochen and Streck, Thomas}}, keywords = {{Asymmetric bargaining power, Nash bargaining solution, Kalai-Smorodinsky bargaining solution}}, pages = {{17}}, title = {{{Distortion through modeling asymmetric bargaining power}}}, volume = {{148}}, year = {{2022}}, } @misc{42326, author = {{N., N.}}, publisher = {{Universität Paderborn}}, title = {{{Manipulation durch Fake-Bewertungen: Einfluss von Such- und Erfahrungsgütern auf das manipulative Verhalten des Verkäufers}}}, year = {{2022}}, } @misc{42322, author = {{N., N.}}, publisher = {{Universität Paderborn}}, title = {{{An Analysis of Coalition Formation Methods to achieve Maximum Social Surplus}}}, year = {{2022}}, } @misc{42324, author = {{N., N.}}, publisher = {{Universität Paderborn}}, title = {{{Die Möglichkeiten der Blockchain-Technologie im Supply Chain Management - eine spieltheoretische Analyse}}}, year = {{2022}}, } @misc{42318, author = {{N., N.}}, publisher = {{Universität Paderborn}}, title = {{{Kindergarten Allocation and the Tradeoff between Stability and Diversity Considerations}}}, year = {{2022}}, } @misc{42319, author = {{N., N.}}, publisher = {{Universität Paderborn}}, title = {{{Effect of the Agent's bargaining positions in the efficiency of matching markets}}}, year = {{2022}}, } @misc{42323, author = {{N., N.}}, publisher = {{Universität Paderborn}}, title = {{{Stabile Zuordnung mit Paaren - Der neue NRMP Algorithmus}}}, year = {{2022}}, } @misc{42320, author = {{N., N.}}, publisher = {{Universität Paderborn}}, title = {{{School choice with reserves and quotas}}}, year = {{2022}}, } @misc{42325, author = {{N., N.}}, publisher = {{Universität Paderborn}}, title = {{{Organisation von Zeitbörsen}}}, year = {{2022}}, } @article{30940, abstract = {{We analyse the two-dimensional Nash bargaining solution (NBS) by deploying the standard labour market negotiations model of McDonald and Solow (1981).
