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. https://ris.uni-paderborn.de/download/1139/5307/KaimannHoyer.pdf application/pdf Taylor and Francis Online2019 eng 10.1080/13504851.2018.1436141 26154-57 Kaimann, Daniel, and Britta Hoyer. “Price Competition and the Bertrand Model: The Paradox of the German Mobile Discount Market.” <i>Applied Economics Letters</i> 26, no. 1 (2019): 54–57. <a href="https://doi.org/10.1080/13504851.2018.1436141">https://doi.org/10.1080/13504851.2018.1436141</a>.
