Heterogeneous Consumer Expectations and Monopoly Pricing for Durables with Network Externalities

This paper studies the optimal pricing and diffusion of durable goods that exhibit positive network externalities, when consumers are heterogeneous in their expectations about future network sizes. We consider the existence of naive consumers, as well as of sophisticated consumers having fulfilled expectations. We find that the firm charges the sequential-diffusion pricing that makes sophisticated consumers function as early adopters, unless consumers quickly become bored with using the goods and/or unless the firm heavily discounts its future profits. We also compare the profitability of three possible pricing strategies with different commitment powers: fixed, responsive, and pre-announced pricing

Corporate Social Responsibility and Strategic Relationships

We analyze a delegation game relevant to the conduct of corporate social responsibility (CSR) in which the firm's owner offers the manager a contract consisting of firm profit and social welfare. We derive three results that distinctly differ from existing findings. First, CSR decisions are strategic complements for firms. Second, with simultaneous CSR decisions, the equilibrium price is equal to marginal cost, despite the fact that firms compete in a Cournot duopoly. Finally, with sequential CSR decisions, unlike the follower firm, the leader firm never exhibits CSR. However, the follower firm can enjoy a profit equal to that derived by the leader in a Cournot-Stackelberg game

Pricing and Diffusion of Durables with Network Externalities

This paper considers the optimal pricing and diffusion of a durable good that exhibits positive network externalities, when consumers are heterogeneous with respect to their expectations about future network sizes. We consider the existence of naive consumers, as well as of sophisticated consumers who have fulfilled expectations about future network sizes. At the time of purchase, naive consumers presume that the current network size will continue over future periods. We find that the firm charges the sequential-diffusion pricing that makes sophisticated consumers function as early adopters, unless consumers quickly become bored with using the goods and/or unless the firm heavily discounts its future profits. In addition, we show that naive consumers may enjoy a greater surplus than do sophisticated consumers, implying that the firm benefits when more consumers are sophisticated. We also compare the profitability of three possible pricing strategies with different commitment powers: fixed, responsive, and pre-announced pricing

Duration of Price Promotion and Retail Profit: An In-depth Study Based on Point-of-Sale Data

Anecdotal evidence has shown that retail price promotions can help small and medium-sized retailers enhance their sales, and thus, retail profits. However, most marketing managers usually stop a promotion after a certain duration. This study aims to explain why these retailers discontinue their price promotion. Our approach posits that the promotion’s overall contributions to the total retail profit progressively diminish with time. We present a theoretical framework to explain the relationship between duration and profit effects of price promotions and propose a statistical model to empirically examine this framework using point-of-sale (POS) data. Our findings provide empirical support that the overall profit effects of price promotions have a downward trend with elapsed time, upholding the hypothesis. The results are helpful for marketers to understand how price promotions dynamically influence retail profits and when the promotion should be terminated
