In this research, we develop a changepoint model to capture the underlying shifts in social media content. We extend latent Dirichlet allocation (LDA), a topic modeling approach, by incorporating multiple latent changepoints through a Dirichlet process hidden Markov model that allows for the prevalence of topics to differ before and after each changepoint without requiring prior knowledge about the number of changepoints. We demonstrate our modeling framework using social media posts from brand crises (Volkswagen’s 2015 emissions testing scandal and Under Armour’s 2018 data breach) and a new product launch (Burger King’s 2016 launch of the Angriest Whopper). We show that our model identifies shifts in the conversation surrounding each of these events and outperforms both static and other dynamic topic models. We demonstrate how the model may be used by marketers to actively monitor conversations around their brands, including distinguishing between changes in the conversation arising from a shift in the contributor base and underlying changes in the topics discussed by contributors.","PeriodicalId":423558,"journal":{"name":"Mark.

This research evaluates one such consumer protection policy and its effectiveness from both marketing and public policy perspectives. Specifically, we investigate the impact of usage restriction in South Korea on both gamers and the industry using individual-level game usage and spending data. Combining the difference-in-differences approach with a regression discontinuity design and propensity score matching, we show that although the regulation reduces overall game usage, the effects vary depending on past behaviors; that is, counter to expectations, the regulation effect, although negative for average gamers, is less so for heavy gamers and in fact directionally flips for the heaviest gamers. Furthermore, we find that its revenue impact is negligible, suggesting that gamers do not change spending patterns because of the intervention. Thus, usage restriction laws may deter light gamers from potentially excessive gaming but do not work well to dissuade heavy gamers, suggesting that a more nuanced approach (as opposed to a blanket usage restriction law) may be called for. Finally, we discuss the implications of such usage restriction laws as a vehicle to control overconsumption and protect consumers.","PeriodicalId":423558,"journal":{"name":"Mark.
