本文研究了1998 - 2001年数码相机市场竞争对产品创新的影响。分析是基于结构动态模型，估计和用于模拟企业的创新行为在反事实的环境。该模型的特点是不同的消费者，谁的时间最佳购买商品，这取决于预期的价格演变和可用相机的特性。在供给方面，企业引入新的相机模型并选择其特性，考虑新产品的动态价值和消费者的最佳动态行为。反事实模拟意味着，行业竞争的增加不会产生平均更好的产品，而是会产生平均质量较低的产品，这取决于竞争的类型。
This paper studies the effect of competition on product innovation in the market for digital cameras during the years 1998 to 2001. The analysis is based on a structural dynamic model that is estimated and used to simulate the innovation behavior of firms in counterfactual environments. The model features heterogeneous consumers, who time optimally purchase goods, depending on the expected evolution of the prices and the characteristics of available cameras. On the supply side, firms introduce new camera models and choose their characteristics, accounting for the dynamic value of new products and the optimal dynamic behavior of consumers. The counterfactual simulations imply that an increase in competition in the industry would not have generated better products on average and, depending on the type of competition, would have generated products with lower average quality.
