| Abstract: | On many two-sided platforms, users on one side not only care about user participation and usage levels on the other side, but they also care about participation and usage of fellow users on the same side. Most prominent is the degree of seller competition on a platform catering to buyers and sellers. In this paper, we address how seller competition affects platform pricing, product variety, and the number of platforms that carry trade. |
| Keywords: | network effects, two-sided markets, platform competition, intermediation, pricing, Imperfect Competition |

| Abstract: | This paper analyzes two business practices on the mobile internet market, paid prioritization and zero-rating. Both violate the principle of net neutrality by allowing the internet service provider to discriminate different content types. In recent years these practices have attracted considerable media attention and regulatory interest. The EU, and until recently the US have banned paid prioritization but tolerated zero-rating under conditions. With prioritization, the ISP delivers content at different speeds and it is equivalent to a discrimination in terms of quality. With zero-rating, the ISP charges different prices for content and it is equivalent to a discrimination in terms of prices. We first show that neither of these practices lead to the exclusion of a content provider, a serious concern of net neutrality advocates. The ISP chooses prioritization when traffic is highly valuable for content providers and congestion is severe, and zero-rating in all other cases. Furthermore, investment in network capacity is suboptimal in the case of prioritization and socially optimal under zero-rating. |

| Abstract: | Digital is at the origin of a major shift like the ones which have occurred in human history such as the introduction of tool, fire, writing and printing. The enterprise is directly concerned in its way to act, its organization and its activities. These mutations result from the combination of internal and external agents for change. If information and communications technologies – ICT– can erase physical distances they do not reduce cultural differences. Does ICT intermediation exempt from the knowledge of the Other? This article presents the organizational impacts resulting from this revolution on international management of remote teams as well as the challenges managers have met and the solutions they have implemented. |
| Abstract: | Le numérique est à l'origine d'un changement majeur comme l'ont été, dans l'histoire de l'humanité, l'introduction de l'outil, du feu, de l'écriture ou de l'imprimerie. L'entreprise est directement concernée dans sa façon d'agir, dans son organisation et dans ses métiers. Ces mutations résultent de la combinaison entre agents internes et agents externes du changement. Les Technologies de l'Information et de la Communication (TIC), si elles effacent les distances géographiques, ne réduisent pas pour autant les distances culturelles. L'intermédiation par les TIC du management international, dispense-t-elle de la connaissance de l'autre ? Cet article présente les impacts organisationnels de cette révolution sur les entreprises et notamment dans le management international des équipes à distance (EAD) mais également les difficultés rencontrées par les managers et les solutions mises en œuvre à partir d'exemples concrets d'EAD.mais surtout le contexte géographique et structurel. |

| Abstract: | The FinTech sector has begun to grow rapidly in sub-Saharan Africa. I document far greater adoption of social media, digital currency, ride sharing, and other FinTech applications in countries with a common law legal heritage compared to those with a civil law system, suggesting that legal origin plays a critical role in setting the stage for growth through entrepreneurship in the developing world. The electrical, telecom, and Internet infrastructure required for FinTech has been built out more extensively in common law countries. Financial inclusion outcomes are also better in emerging markets that have a common law heritage. |

| Abstract: | We design and experimentally evaluate two low-cost, scalable interventions – an online preparatory module and a text-message coaching program – in a sample of over 3,000 undergraduate students at a large Canadian university. Supplementing administrative data on academic outcomes with a unique follow-up survey on student well-being and study habits, we estimate positive program effects on students’ non-academic outcomes, despite estimating null effects on course grades and credit accumulation. Given the low costs associated with administering these programs, our results suggest that the positive impacts on student experiences may warrant program expansion even in the absence of impacts on academic outcomes. |
