Dynamic pricing of network goods in duopoly markets with boundedly rational consumers

In this paper, we present a dynamic pricing model for two firms selling products displaying network effects for which consumers are with bounded rationality. We formulate this model in the form of differential games and derive the open-loop equilibrium prices for the firms. Then, we show the existence and uniqueness of such open-loop equilibrium prices. The model is further extended to the case with heterogeneous network effects. Their steady-state prices obtained are compared. A numerical

They have different level of sensitivity to network effects. So, the utility of a consumer purchasing an online game depends on his/her preference gained from learning, the price and the heterogeneous network effects. We will model this utility in Section 3. Recently, a rapid growth in information technology has enabled many firms to monitor the demand of their products in real time and adjust prices dynamically in response to the changes in demand patters (Levin, McGill, and Nediak [27]). Many retailers are now re-examining their pricing policies and exploring means of implementing dynamic pricing approaches that are more responsive to consumer demand (Elmaghraby and Keskinoacak [18], Herbon [22] , Khouja [25]). Hence, it is of great significance for firms to incorporate network effects and consumer s learning behavior into their pricing policies in order to attract more consumers and hence attain more profits. Nowadays, many pricing models of network goods are assumed to be in a monopolistic market. In this way, explicit consideration of competitors can be avoided. However, pure monopolistic market or pure competitive market is rarely observed in reality. So the analysis of oligopolistic, especially duopolistic dynamic pricing of network goods is required. The remainder of the paper is organized as follows: Section 2 provides a brief review of related literatures. In Section 3, the basic model is formulated. We analyze the equilibrium of our model in Section 4. We then extend it to the case with heterogeneous network effects in Section 5. We perform numerical examples in Section 6 and make some useful concluding remarks in Section 7. 2. Literature review. Following seminal works by Farrell and Saloner [19] , and Katz and Shapiro [24], network effects have been extensively studied in the economics literature (Damiano and Hao [11], Ellison and Fudenberg [16], and see Economides [15] for a more detailed review). Broadly speaking, there are two kinds of network effects, global network effects and local network effects. The main difference is which one causes the consumer s utility to increase. The former one means that a consumer s utility for a good depends on the total consumption while the later one means that a consumer gains his/her utility if his/her neighbour purchases the same good (Bloch and Querou [5], Candogan, Bimpikis, and Ozdaglar [8]). In our model, we consider only global network effects. Monopoly dynamic pricing models for network goods have been studied in the literature (Cabral, Salant, and Woroch [7]). For example, Bensaid and Lesne [4] consider pricing for a monopolist with goods that display positive network externalities and show that subperfect game equilibrium prices go up as time passes. Dhebar and Oren [12] study the optimal dynamic pricing of a new product or service in the presence of network effects. This work maximizes the present value of the monopolist s profit where the dynamics is the demand for network access. However, our model maximizes the discounted total profits of both firms. More recently, Radner, Radunskaya, and Sundararajan [29] consider dynamic pricing of network goods when facing boundedly rational consumers, which is in contrast with the standard notion of a rational-expectation equilibrium. In their model, only a random fraction of consumers, called inattentive consumers (Gabaix [20] [21]), pays attention to the price change in each period. However, pure monopoly rarely exists in real market. So optimal pricing under competition has received considerable attention recently (Ellison, Fuderberg and Mbius [17], Xu and Cai [31], Zhang, Bai and Tang [32]). Furthermore, Anderson
