Since it belongs to the 'free-to-play games', the company has to optimize the in-game-shop to generate revenues. Product differentiation is one possibility to optimize the profitability of the game. In this paper, we use a microeconomic approach in order to highlight the implications of product differentiation for the profit maximization problem.}, language = {en} } @techreport{MoritzStadtmann2021, type = {Working Paper}, author = {Moritz, Karl-Heinz and Stadtmann, Georg}, title = {To vaccinate or not to vaccinate?
