1. Why did Uber China fail? : lessons from business model analysis
abstractThe ride-hailing platform offers the business model of the on-demand business ecosystem in the era of the sharing economy. Platforms such as Uber, Lyft, and DiDi have become popular worldwide and established a strong position in urban transportation. This paper presents a case study analyzing the fierce competition between Uber and DiDi in the Chinese ride-hailing market. First, employing the canvas framework, we show the core characteristics of the business models of the two platforms. Our analysis and comparisons of the strategic positioning and implementation concerning the building blocks of canvas ascribe the success factors of DiDi and the causes of Uber’s failure. Although both Uber and DiDi provide similar service offerings for diverse market segments, Uber’s mismatches between its strategic focus on the premium segment and service operations proved to be a mistake. On the other hand, DiDi managed its business more efficiently by providing a wide range of service offerings while leveraging the two-sided market. As a result, DiDi has grown successfully as a one-stop transportation platform, which is well-suited to the Chinese market. This study provides meaningful insights into business model innovations in the sharing economy and implications for the evolution of future transportation platforms.

3. A comment on "The Effects of Racial Diversity in Citizen Decision-Making Bodies"
abstractKarpowitz et al. (2024) examine the effect of racial diversity on group decisionmaking. The authors used OLS regression to analyze 2,694 citizens randomly assigned to 449 mock juries who are tasked to make decisions, and they find that the number of the people of color (POC) affects private decisions, but not so much on group decisions. We successfully replicated the main results of the paper with no coding errors, and we implemented the following robustness checks. First, we reset different seeds and found that they do not change the tables or the graphs, so the findings are not subject to arbitrarily chosen seed. Second, we applied multiple imputations rather than list-wise deletion for a few variables which the authors removed for containing missing values. While the original result continues to hold, our findings suggest that the presence or absence of even one individual of POC on the jury might be more significant than the incremental increases of the number of POC on the jury. Third, we shifted from using POC as the independent variable to using Black as the binary independent variable. When the group's racial composition is framed as Black versus non-Black, we do not observe a significant impact on individual punitiveness after deliberation. In addition, juries with one or no Black members showed greater punitiveness in their initial verdicts compared to juries with two or more Black members, but this effect diminished by the second round.

6. Equilibrium analysis for platform developers in two-sided market with backward compatibility
abstractWe consider a dominant platform provider operating both legacy and new platforms that connects users with suppliers in a two-sided market context. In addition to the typical indirect network effects in the two-sided market, backward compatibility works on the new platform. Thus, users joining the new one can also enjoy the services provided by suppliers using the legacy platform. Users and suppliers are linearly differentiated between two platforms as in the Hotelling model and play a subscription game of choosing one platform at the lower level. The suppliers in the new platform may suffer from congestion, which can be alleviated by platform provider’s investment on the new one. The platform provider also determines price margins for the supplier sides. Our equilibrium (eq.) analysis in the subscription game identifies an interior eq. (coexistence of both platforms in both sides). Though the backward compatibility plays a stabilizing role for the interior eq., its stability is fragile due to the network effects. Rather, some boundary eq.’s, where at least one side tips to the legacy or the new platform, are more likely to be stable. The backward compatibility is a key factor that characterizes the stable boundary eq.’s. The upper stage game is led by the platform provider, which tries to maneuver the system toward one of the stable boundary eq.’s using price margins and investment. The platform provider prefers an all-new boundary eq. when the indirect network effect and the maximum price margin for the new platform are large; thus, it puts a significant investment in the new one. With a small indirect network effect for suppliers, however, the platform provider does not invest in the new platform and choose a separate boundary eq. where two sides split into different platforms. Whether the user side completely tips to the new one (completely separated eq.) or not (partially separated eq.) depends on the backward compatibility. The relative advantage of the all-new eq. over the separate eq.’s in terms of social welfare from both sides depends on the backward compatibility as well as the indirect network effects for the new platform.

7. Why did Uber China fail in China? : lessons from business model analysis
abstractThe ride-hailing platform presents an on-demand business model on the basis of business ecosystems in the era of the sharing economy. The ride-hailing platforms became popular and common around the world as a sustainable option that complements the public transportation services. This article presents a case study that analyzes the intense competition between global giant Uber and Didi Chuxing in Chinese ride-hailing market. First, employing the Canvas model, we compare and analyze the characteristics of the business model of the two platforms. Our analysis and comparisons of the strategic positioning and implementation of the two platforms with respect to the major building blocks of the Canvas model finds out the success factors of Didi as well as the sources of failure of Uber. For example, although both Uber and Didi provided similar service offerings covering diverse market segments from low- to high-ends, Uber's mismatches between its strategic focus on the high-end premium segment and service operations proved to be a mistake. On the other hand, Didi operated its business more efficiently by providing a wide range of service offerings and leveraging the two-side market properly. As a result, Didi has grown successfully as a one-stop transportation platform, which is well suited to the Chinese market. This study provides important insights into business model innovations in the sharing economy and implications for the evolution of future transportation platforms.
