5 Appendix: Selected Abstracts Gil Appel, Barak Libai, and Eitan Muller, How Free Products Grow: Adoption Patterns in Fast Moving Digital Goods, Working on submission for 2 nd round in Marketing Science, Job Market Paper Free product offerings, or freeware, dominate online markets yet our knowledge and theories about their growth originate mainly from conventional goods. We demonstrate that growth dynamics of freeware are different for those observed for conventional new products. Using a large-scale dataset that documents the growth of close to sixty thousand free digital products, and supported by an additional analysis of thousands of mobile apps, we find that freeware products display three distinct patterns of growth: bell-shaped pattern ( Diffuse ) which are largely left skewed, exponential-type decline ( Slide ), and a combination of the two ( Slide and Diffuse ). We further show a robust relationship between freeware popularity and growth pattern ubiquity, providing the first evidence on a relationship between products popularity and growth patterns. We define two critical effects idiosyncratic to freeware that help to explain the patterns observed: Reliance on recent adoptions - distinct from cumulative adoption - which we label the recency effect; and the disproportional effect of early period external effect which we label the inception effect. Indeed we find that it is recent adoption, more than cumulative adoptions that were historically highlighted in the new product growth literature, that help to explain the difference in popularity among freeware. Overall, we highlight the need to adapt our knowledge on new product growth and its modeling to the fast moving world of free digital products. Gil Appel, Barak Libai, and Eitan Muller, The Financial Impact of Knockoffs on the Original Fashion Design, Working on submission for 2 nd round in the Journal of Marketing Whether to legally protect original fashion designs against knockoffs is an ongoing debate among US legislators, industry groups, and legal academic circles, with a disagreement even on the fundamental question of whether the effect of a knockoff on the profits of an original design is positive or negative. Yet to-date this discussion has not utilized marketing knowledge and formal approaches, which are very relevant to questions raised. We combine data collected on the growth of fashion items with industry statistics, to create the first formal analysis of the essential questions in the base of the public debate. Our results highlight the negative role of ubiquity of the design, which can affect the original design demand due to consumers quest for uniqueness, and show how it can have an extensive impact on original design profitability. We explore the contribution of the opposing forces that constitute the knockoff financial effect on original designs, and discuss the implications of a suggested legal protection period on this effect.

6 Gil Appel, Barak Libai, and Eitan Muller, Freemium Monetization in the Presence of Customer Attrition, Work in Progress, In preparation for submission to Marketing Science Free product offerings dominate online markets, yet firms struggle to monetize such products and make profits relying on both advertising income and content sold to consumers. We highlight the importance of retention considerations in determining optimal firm behavior in digital markets involving free products. We look at product stickiness consumers tendency to re-use the product in future periods and consider a case, based on a prevalent business model, in which the firm offers a free, advertising-based version of a product alongside an ad-free version that customers can purchase out-of-pocket. We show that in such markets, stickiness largely drives the dynamics that emerge with different equilibria based on stickiness level. Stickiness drives the firm s optimal decisions regarding advertising intensity and price, as well as the composition of the customer base. Specifically, price for the paid version increases with stickiness, while optimal advertising intensity is non-monotonic. Beyond a certain level of stickiness, both price and advertising increase, with price increasing more rapidly, and the proportion of free users increases at the expense of the proportion of paying users.
