This dissertation investigates the profitability of loyalty programs in a competitive environment. Loyalty programs are prevalent marketing tools that encourage repurchase intentions among customers, and increase long-term profitability of firms. However, there is no consensus among researchers regarding the effectiveness of these programs in a competitive environment. This thesis responds to this line of research by developing game theoretic models that incorporate customers’ valuations of reward and time, two factors that have not been considered simultaneously in previous studies on the profitability of loyalty programs. The results show that for firms offering undifferentiated products (e.g., coffee shops), offering loyalty programs is a dominant and profitable strategy for the competing firms only when customers highly value rewards, but not time. After assessing the profitability of loyalty programs, the thesis investigates LP design issues related to the effectiveness of restricting redemption. This aspect of loyalty program design has received minimal attention in the literature. Nine sub-games between two competing firms are solved in which each firm applies one specific restriction level on redemption (unrestricted, low restricted, or high restricted), and optimal decision variables are obtained for each scenario. Based on the Nash equilibria of the sub-games, the main game is solved in which the firms decide about the level of restriction on their loyalty programs, which maximizes their profit. The results show that firms should follow highly restrictive policies at equilibrium, but not when customers highly value time over reward. When the latter is the case, a prisoner dilemma occurs. Firms should react by applying redemption policies that are the least restrictive at equilibrium. Furthermore, when customers do not highly value neither time nor reward, a prisoner dilemma arises that suggests the firms to offer a low restricted redemption policy at equilibrium. In addition to these findings, this thesis contributes to the literature by developing comprehensive analytical models, that are stochastic and competitive, and that incorporate psychological theories.
