Consumers’ purchase decisions depend on whether a product is perceived as a bargain or as overpriced. But how do consumers evaluate sales prices? The standard approach in economics, psychology, and marketing suggests that consumers’ estimates are best described by a attribute-based or piecemeal strategy that integrates information about products in a linear additive fashion. Here, we...

In management research, empirical data are often analyzed using p-value null hypothesis significance testing (pNHST). Here we outline the conceptual and practical advantages of an alternative analysis method: Bayesian hypothesis testing and model selection using the Bayes factor. In contrast to pNHST, Bayes factors allow researchers to quantify evidence in favor of the null...

Many cognitive theories of judgement and decision making assume that choice options are evaluated relative to other available options. The extent to which the preference for one option is influenced by other available options will often depend on how similar the options are to each other, where similarity is assumed to be a decreasing function of the distance between options. We...

Sie werden als Zeichen von Leistung und Erfolg bewundert, aber auch als Ort der Machtkämpfe und Bürokratie misstrauisch beäugt. Haben Konzernzentralen in Zeiten der digitalen Vernetzung und der Globalisierung noch einen Sinn?

Das Jahr 2014 war ein Rekordjahr auf dem Schweizer M&A-Markt. So stieg die Anzahl der Transaktionen um 33% von 315 im Jahr 2013 auf nunmehr 420 an. Auch der Fünf-Jahres-Vergleich zeigt, dass die Anzahl angekündigter Deals die Werte aus den Jahren 2010 bis 2012 übertraf. Noch positiver fällt der Blick auf die Entwicklung des Dealvolumens im vergangenen Jahr aus, das zuletzt 188,1...

Most articles on sports economics presume the well-known Nash equilibrium concept. In this article, however, we apply evolutionary game theory in a sports-contest model. If clubs follow evolutionarily stable strategies (ESS), then ESS generate greater investments and smaller profits than predicted by Nash’s strategies, independent of whether a club is win-maximizing or profit-...

The early tenure of a new Chief Executive Officer (CEO), also referred to as ‘the CEO post-succession process’, is a critical phase in the history of an organization, because it is associated with a high rate of organizational failure and CEO dismissal. Research on this important process has grown rapidly over the last decade, focusing particularly on the question of how the match...

Recently, Cánovas et al. presented an interesting result: the argmin mapping of a linear semi-infinite program under canonical perturbations is calm if and only if some associated linear semi-infinite inequality system is calm. Using classical tools from parametric optimization, we show that the if-direction of this condition holds in a much more general framework of optimization...
