Do non-monetary virtual gifts enhance or diminish voluntary paid gifts? Evidence from a  video game live streaming platform? 

Peiyan Yu, Raveesh Mayya, Anindya Ghose (2nd Round Major Revision at Information Systems Research)  

We utilized a quasi-experiment to investigate the effects of enabling non-monetary virtual gifts on the streamers’ revenue outcome via paid virtual gifts and find a stimulating effect instead of cannibalization.  Mechanism analyses suggest competition among users on gifting value and habit forming.

Managing social interactions on two-sided live-streaming platforms - A structural model of  digital labor

Peiyan Yu, Runshan Fu, Anindya Ghose (Preparing for submission)

In this paper, we study content creators’ social interaction effort decisions on a live-streaming platform with a Hidden Markov Model. We find that while social interactions under a live-streaming context are generally considered stimulating, these efforts bear costs and increase the likelihood of a streamer developing mental fatigue in the long-term. Moreover, streamers with a smaller loyal community base or lower-status that reflects overall devotion and capability suffer stronger exhaustion effects from social interactions. Our results suggest that platforms should consider developing tools to lower the streamers' cognitive cost of social interactions while maintaining audience engagement.

The Impact of GenAI on Freelancer Job Preferences and Bidding Behaviors: Evidence from a Randomized Field Experiment

Peiyan Yu, Sonia Jaffe, Nicole Immorlica, Ted Liu, Kelly Monahan (Under Review)

Generative AI has recently experienced rapid breakthroughs, offering powerful new capabilities in knowledge work. Yet how these tools might reshape worker behavior in real-world labor markets remains largely unknown. This study investigates the impact of a generative AI tool, Microsoft 365 Copilot, on freelancers' job application and completion behaviors through a field experiment on an online labor marketplace. The results illustrate strategic behavior changes in bidding patterns and highlight the differential impacts of generative AI on freelancers, shaping strategic job selection and bidding, and offer insights into digital labor markets, future of work and implications for platform design in AI-assisted work environments.

General Equilibrium of an Online Labor Market under the Impact of Generative AI Tools

Thi Mai Anh Nguyen, Peiyan Yu, Sonia Jaffe, Nicole Immorlica, Ted Liu (Work in progress)

While initial experimental observations indicate shifts in freelancers’ preference changes following the use of GenAI productivity tools, understanding the mechanism of changes and predicting the long-term distributional benefits of GenAI on bidding and hiring outcomes is crucial.  This project extends the partial equilibrium freelancer job preference changes to build a general equilibrium model and answer the question how the broader market dynamics evolves as AI usage matures overtime. 

A New-form of Sociality: Characterizing Online Communities of Embodied AI Streaming Channels

Peiyan Yu, Joao Sedoc (Work in progress)

As social media especially live streaming platforms attract its users that seek sociality and the sense of community, introduction of Vtubers (Emobied by AI-generated avartar, voice, and script) may disrupt but induce new types of sociality. In this project we utilize the structures of transformers to model user community development process and characterize emerging sociality.
