Comment on Telemarketing Sales Rule Review: In my research group, we conduct theoretical and empirical studies on privacy, security and online marketing problems. Relevant to the TSR review, we have studied how susceptible individuals are to different variations of post-transaction marketing practices. We have planned and conducted online experiments with hundreds of consumers who have spent actual money on desirable purchases, and have also been presented with low-value post-transaction marketing offers. One particular focus of our work is to better understand the effectiveness of the rules and stipulations of the Restore Online Shoppers' Confidence Act (ROSCA). For example, we test the impact of having to take an affirmative action to accept a post-transaction marketing offer. While our work is focused on the online context, we believe that our findings about the impact of various design choices on consumer behavior also translate to the context of the TSR. Our work has been partly published as: Alan Nochenson and Jens Grossklags (2014) "An Online Experiment On Consumers' Susceptibility to Fall for Post-transaction Marketing Scams". In: Proceedings of the 22nd European Conference on Information Systems (ECIS). The research paper is available on the authors' websites. A second working paper is currently under review, and will be made available also on our websites.
