Performance evaluation for universities or research institutions has become a hot topic in recent years. However, the previous works rarely investigate the multiple departments’ performance of a university, and especially, none of them consider the non-homogeneity among the universities’...

We consider a supply chain in which an original equipment manufacturer (OEM) procures a key component from a supplier. We consider an ingredient branding strategy under which the supplier and the OEM form a brand alliance. Specifically, the supplier invests in ingredient branding to build up her...

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...

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...

The utilization of coal and other fossil fuels is becoming increasingly restricted. Straw biomass, as a clean and renewable energy, plays a significant role in achieving zero carbon emissions. However, straw biomass is prone to slagging in the combustion process due to its high alkali metal...

The $807B digital content industries (e.g. ebooks, music, gaming) implement freemium pricing, offering initial contents for free (e.g. first few book chapters) and monetizing later contents with a premium. Determining the optimal amount of free content, or conversely optimal charging position...
