讲座内容：

Generational product innovations (GPI) are critical for digital products to keep updated and stay competitive, but may also be considered a tool of planned obsolescence, causing resistance from users. This study draws on the demand-side perspective to examine how firms should deal with the dilemma. We argue that GPIs reduce the usage of the product because generational change brings disruption upon the mass of users. Furthermore, we contend that GPI’s performance effect is conditioned by product performance and the prior number of GPIs throughout the product life cycle. The impact of GPI will be dampened when the product attains top performance, and will be amplified when the product has experienced more generational progress. We test our hypotheses in the context of the mobile computing industry. Utilizing a matched difference-in-differences design taking advantage of the asynchronous generational updates of the same multi-homing apps across two dominant mobile platforms, we identify the causal effects of major app updates on the demand and total revenues of the apps, respectively. Our analysis of 48 mobile game apps across 58 countries confirms the hypotheses, and it shows that new insights can be gained through a demand-side lens into routine innovation strategy.
