Since its foundation, China’s government auditing system has played a very important role in maintaining financial and economic order and improving government accountability and transparency. Though a great deal of research has discussed the role of government auditing in discovering and...

We study how search and information frictions shape market dynamics in global e-commerce. Observational data and self-collected quality measures from AliExpress establish the existence of search and information frictions. A randomized experiment that offers new exporters exogenous demand and...

With the advent of general-purpose Generative AI, the interest in discerning its impact on the labor market escalates. In an attempt to bridge the extant empirical void, we interpret the launch of ChatGPT as an exogenous shock, and implement a Difference-in-Differences (DID) approach to quantify...

We propose a new ensemble classification algorithm, named super random subspace ensemble (Super RaSE), to tackle the sparse classification problem. The proposed algorithm is motivated by the random subspace ensemble algorithm (RaSE). The RaSE method was shown to be a flexible framework that can...

Online reading platforms offer a by-chapter purchase method and implement a novel in-chapter online review function to mitigate consumer uncertainty regarding the true quality of e-books. In this study, we seek to uncover how such intervention affects consumer purchase decisions. In particular,...

This paper examines whether digital goods consumption is resilient to air pollution. Leveraging the seminal instrument of spatial regression discontinuity for air pollution induced by the Huai River heating policy, we show a sharp, discontinuous drop in the individual-level consumption on a...

Large Language Models (LLMs) technology, e.g., ChatGPT, is expected to reshape a broad spectrum of domains. Among them, the impact on user-generated knowledge-sharing (Q&A) communities is of particular interest because such communities are an important learning source of LLMs, and their future...
