We propose an information production model to explore the mechanism of the process from entry barriers to market quality. Entry barriers depicted by a level of information precision, affect the interactive behavior between information producers and rational investors, thereby acting on market...

The transaction-level analysis of security price changes by Madhavan, Richardson, and Roomans (1997, hereafter MRR) is a useful framework for financial analysis. The first-order Markov property of trading indicator variables is a critical assumption in the MRR model, which contradicts the...

We investigate the impacts of the short-termism on multiple equilibria in a dynamic rational expectations equilibrium model. We find that short-termism is not the cause of equilibrium multiplicity but affects market quality of all equilibria. The liquidity, price efficiency and expected trading...

Transaction-level analysis of security price change due to Madhavan, Richardson and Roomans (1997, hereafter MRR) has been a useful framework in financial analysis. The one order Markov property of the trade indicator variables is a key assumption in the MRR model, which contradicts the...

We construct a two-period Kyle model to investigate how a financial online influencer manipulates the stock market. Given that an online influencer usually has many loyal fans, he firstly places a random order in the market and transmits the order signal to his fans, and then engages in...

We apply Multi-Agent Deep Reinforcement Learning (MADRL) to inventory management problems with multiple echelons and evaluate MADRL's performance to minimize the overall costs of a supply chain. We also examine whether the upfront-only information-sharing mechanism used in MADRL helps alleviate...
