讲座内容简介:  

Information is one of the most important channels in business decision making, and a platform can manage information disclosed to consumers in order to maximize its profit. In this paper, we analyze the information announcement strategy for an on-demand platform with service differentiation, in which the platform provides not only the standard service with stochastic stock-out risk, but also a more profitable guaranteed service. Consumers' preferences can be influenced by the service availability information announced by the platform. Thus, designing a state-contingent probabilistic disclosure strategy via a Bayesian persuasion approach will be optimal for the platform to boost its profit in both short-run and long-run. This is because the strategy allows the platform to announce a higher stock-out rate of the stochastic service which could persuade more customers to adopt the guaranteed service. By fully characterizing the conditions under which the platform discloses full, partial, and no information, respectively, we conduct analyses on the consequences for the platform's profit, consumer surplus, and social welfare. Investigating the impact of two complementary policies -transparency policy and accessibility policy - this study reveals that these two policies, aiming to subsidize consumer surplus at the cost of platform's profit, have very narrow feasible regions, beyond which they could backfire, causing further negative effects to social welfare. Our study has important policy implications for regulators, and provides a better understanding of the information manipulation incentive in an on-demand platform of differentiated services with information asymmetry between the platform and consumers.
