Long‐term competition for product awareness with learning from friends
研究消费者通过朋友网络获取产品信息时，企业长期价格竞争与市场份额的演化，分析网络结构（如连接性和同质性）对市场结果和福利的影响。
Abstract We study a dynamic model of price competition with differentiated products in which new generations of consumers acquire information about available products from their friends of previous generations. The social network, which links consumers across generations, affects the evolution of consumers' awareness of products and firms' long‐term (steady‐state) market shares. Focusing on steady‐state equilibria, we examine how the structure of the social network—including connectivity and homophily—influences market shares, pricing, and welfare.
