Experiments on the Ultimatum Game (UG) repeatedly show that people's behaviour is far from rational. In UG experiments, a subject proposes how to divide a pot and the other can accept or reject the proposal, in which case both lose everything. While rational people would offer and accept the...

Communities are common in complex networks and play a significant role in the functioning of social, biological, economic, and technological systems. Despite much interest in detecting community structures in complex networks and exploring the effect of communities on collective dynamics, a deep...

We study dynamic network games with two types of players (i.e., heterogeneous players) characterized by their different intrinsic preferences. Instead of calculating the Nash equilibrium, we focus on the asymptotic behavior of an asynchronous best response dynamics. We develop a dynamic approach...

Sentiment analysis is a vital tool for uncovering insights from financial articles, news, and social media, shaping our understanding of market movements. Despite the impressive capabilities of large language models (LLMs) in financial natural language processing (NLP), they still struggle with...

We propose a two-sided market entry game and present experiments studying coordination behavior in the game. The two-sided market in the game is operated by an intermediary monopoly platform, serving two sides (i.e., customers and service providers) and featuring asymmetric agents, cross-side...

Resource allocation decisions can be enhanced by performing risk assessment during the early development phase. In order to improve and maintain the security of the Information System (IS, hereafter), there is need to build risk analysis model that can dynamically analyze threat data collected...

A large body of literature finds that the unexpected trading volume, which is obtained by filtering out time trend, autocorrelation, can be used as a proxy of the information flow and can explain the heteroskedasticity of stock return in some degrees. In this paper, we find that the...
