- 요약This dissertation explores how new technologies shape business competition, entrepreneurship, and societal issues, with a focus on the sharing economy and platforms. I examine how digital platforms and nonmarket forces influence entrepreneurial outcomes, drive strategic responses from incumbent firms, and pose key organizational, social, and economic challenges for policy implementation.Chapter 1 aims to understand how racial backgrounds influence entrepreneurs' business performance in the sharing economy, examining where discrimination is more prevalent, why it occurs, and how racial-minority entrepreneurs can potentially mitigate it. Analyzing all Airbnb listings across the United States from May 2015 to April 2023, I show that Black, Hispanic, and Asian entrepreneurs experience reduced consumer demand for comparable offerings and have higher exit rates. To understand the impact of ideological distance on their success, I examine granular data on public opinion and find that the race effect is more pronounced in conservative ZIP Code Tabulation Areas. Using natural language processing techniques, I also find that while better numerical ratings fail to bolster their performance relative to White entrepreneurs, specific textual reviews provide a pathway to mitigating these disparities. These findings have important implications for the underexplored issue of performance disparities among racial-minority suppliers, as well as the mechanisms that exacerbate or mitigate these biases.Chapter 2, co-authored with Mariko Sakakibara, examines how non-platform incumbents are affected by entrants from the gig and sharing economy, and how they respond. We argue that the innovations brought by these disruptors differ from past disruptive innovations because they possess architectural advantages over resource-constrained incumbents while growing from a niche to compete with resource-rich incumbents. Accordingly, incumbents need to adjust their positioning by competing on price for resource-constrained incumbents and on quality for resource-rich incumbents. Meanwhile, incumbents must consider existing competitive dynamics, especially when disruptors are imperfect substitutes. Using property-level hotel data and a regulatory event restricting short-term rentals to address endogeneity concerns, we find that the impact of these disrupters is greater for resource-constrained hotels, and responses are heterogeneous across incumbent hotels with different organizational characteristics. The performance and responses of non-platform incumbents are further influenced by the intensity of competition among them.Chapter 3, co-authored with Mariko Sakakibara, explores how reviews determine suppliers' performance and facilitate their learning. We examine Airbnb guest text reviews (as opposed to mere numerical ratings), which are critical for enhancing the credibility of hosts; they are also free from fake reviews. Specifically, this paper examines the performance differences between brand-new firms and firms with preexisting capabilities and finds that text reviews significantly influence host performance, with substantial heterogeneity regarding preexisting capabilities and market competition.Finally, Chapter 4 explores how advances in technology and emerging platforms can introduce societal challenges by increasing user victimization in ways previously overlooked. Constructing a novel dataset with monthly panels from January 2005 to December 2018 and exploring state-specific legislation, I show that the rise of online dating services induces sexual crimes, especially in areas without Internet-dating safety laws. While the impact of these state statutes starts dissipating after three years, the evidence underscores the need for online dating companies and policymakers to implement measures to moderate and safeguard these services.
