Underlying a Bertrand model of price competition, we empirically model pricing behaviour in an oligopoly. We analyse panel data of individual pricing information of mobile phone contracts offered between 2011 and 2017. We provide empirical evidence that price differences as well as reputational effects serve as a signal to buyers and significantly affect market demand. Additionally, we find that brands lead to an increase in demand and thus are able to generate spillover effects even after price increase. author: - first_name: Daniel full_name: Kaimann, Daniel id: '18949' last_name: Kaimann - first_name: Britta full_name: Hoyer, Britta id: '42447' last_name: Hoyer citation: ama: 'Kaimann D, Hoyer B.

An interesting scenario\r\nis the formation of an information network where group members individually sponsor costly links. Suppose that ceteris paribus, an outsider\r\nappears who aims to disrupt the information \r\nflow within the network\r\nby deleting some of the links. The question is how the group responds\r\nto this common enemy. We address this question for the homogeneous\r\nconnections model of strategic network formation, with two-way \r\nflow of\r\ninformation and without information decay. For sufficiently low linkage\r\ncosts, the external threat can lead to a more connected network, a positive\r\ncommon enemy effect. For very high but not prohibitively high linkage\r\ncosts, the equilibrium network can be minimally connected and efficient\r\nin the absence of the external threat whereas it is always empty and ineffi\fcient in the presence of the external threat, a negative common enemy\r\neffect.

Whereas the theoretical research on network formation under the threat of disruption has thus gained prominence, hardly any experimental research exists so far. In this paper, we therefore experimentally study the emergence of networks including the aspect of a known external threat by relating theoretical predictions by Dzuibiński and Goyal (2013) to actual observed behaviour. We deal with the question if subjects in the role of a strategic Designer are able to form safe networks for least costs while facing a strategic Adversary who is going to attack their networks. Varying the costs for protecting nodes, we designed and tested two treatments with different predictions for the equilibrium network and investigated whether one of the least cost equilibrium networks was more likely to be reached. Furthermore, the influence of the subjects’ farsightedness on their decision-making process was elicited and analysed.\r\n\r\nWe find that while subjects are able to build safe networks in both treatments, equilibrium networks are only built in one of the two treatments. In the other treatment, predominantly safe networks are built but they are not for least costs. Additionally, we find that farsightedness –as measured in our experiment– has no influence on whether subjects are able to build safe or least cost equilibrium networks. Two robustness settings with a reduced external threat or more liberties to modify the initial networks qualitatively confirm our results. Overall, in this experiment observed behaviour is only partially in line with the theoretical predictions by Dzuibiński and Goyal (2013)." article_type: original author: - first_name: Angelika Elfriede full_name: Endres, Angelika Elfriede id: '48794' last_name: Endres - first_name: Sonja full_name: Recker, Sonja last_name: Recker - first_name: Behnud full_name: Mir Djawadi, Behnud id: '26032' last_name: Mir Djawadi orcid: 0000-0002-6271-5912 - first_name: Britta full_name: Hoyer, Britta id: '42447' last_name: Hoyer citation: ama: 'Endres AE, Recker S, Mir Djawadi B, Hoyer B.
