Topic 1:Big Data Analytics for Sharing Economy Research，谢丽佳(Karen Xie)

Abstract:Big data is receiving continuous and growing attention from researchers and practitioners in academia, industry, and government. It is transforming the source and structure of data and, more importantly, the school of thoughts of business research. In this seminar, the speaker will first discuss emerging technological and methodological innovations of big data analytics, how to transform big data into meaningful and actionable insights, and what are the implications to business scholars. Then she will present a timely collection of new research opportunities in sharing economy through the lens of big data analytics. The seminar will be concluded in a discussion of how sharing economy research would affect the future of the business practice and education.

Topic2:Tax Policy and Equity Investment: Evidence from Equity Crowdfunding，陈伟

Abstract:In this paper, we empirically study whether and how investments in early stage businesses respond to tax incentives, and the subsequent performance of firms that have participated in equity crowdfunding. Our analysis uses the establishment of the Seed Enterprise Investment Scheme (SEIS) in the United Kingdom (UK) as a natural experiment, as well as a comprehensive transaction-level dataset from leading online equity crowdfunding platforms in UK. Our results indicate that investors on average increase their equity investment in SEIS-eligible firms on the crowdfunding platforms after the policy launch. We also find that SEIS-eligible firms that are funded after the policy launch are less likely to dissolve. The results will provide important insights to online equity investment platforms, investors, startups, and regulators.

Topic3:On and Off the Social Web—Connecting Online Social Networks to Offline Behaviors，赵慷

Abstract:The social web has revolutionized the way we interact with each other and with the world around us. Despite the increasing value of the cyberspace, what happens in the offline physical world is still very important nowadays. This talk will focus on what we would know about individuals’ offline behaviors by examining their activities in online social networks. I will cover two of my studies related to this topic, including online community participations and health outcomes, and information and behavior diffusions in viral events. I will also introduce another study on research collaborations in academic institutions.
