Green supply chain integration and financial performance: A social contagion and information sharing perspective

Abstract: Although green supply chain integration (GSCI) has received wide attention, how it diffuses among supply chain members to affect the manufacturer's performance is still unclear This study examines the relationships among GSCI, information sharing, and financial performance from a social contagion lens By conceptualizing GSCI into three forms, two types of contagion mechanisms (ie, cohesion and structural equivalence) were identified to investigate the underlying contagion effects between different forms of GSCI and the effects of various GSCI on information sharing and financial performance Survey data were collected from 206 Chinese manufacturers and analyzed using structural equation modeling to test hypotheses The results indicate that green supplier integration directly promotes green internal integration, green customer integration, and information sharing with suppliers Green internal integration positively influences green customer integration and financial performance Green customer integration enhances information sharing with customers Both information sharing with suppliers and customers improve financial performance This study contributes to the GSCI literature and provides novel managerial implications for manufacturers

Are Price Limits Effective? An Examination of an Artificial Stock Market

Abstract: We investigated the inter-day effects of price limits policies that are employed in agent-based simulations. To isolate the impact of price limits from the impact of other factors, we built an artificial stock market with higher frequency price limits hitting. The trading mechanisms in this market are the same as the trading mechanisms in China's stock market. Then, we designed a series of simulations with and without price limits policy. The results of these simulations demonstrate that both upper and lower price limits can cause a volatility spillover effect and a trading interference effect. The process of price discovery will be delayed if upper price limits are imposed on a stock market; however, this phenomenon does not occur when lower price limits are imposed.

Characteristics of traffic flow at a non-signalized intersection in the framework of game theory

Abstract: At a non-signalized intersection, some vehicles violate the traffic rules to pass the intersection as soon as possible. These behaviors may cause many traffic conflicts even traffic accidents. In this paper, a simulation model is proposed to research the effects of these behaviors at a non-signalized intersection. Vehicle’s movement is simulated by the cellular automaton (CA) model. The game theory is introduced for simulating the intersection dynamics. Two types of driver participate the game process: cooperator (C) and defector (D). The cooperator obey the traffic rules, but the defector does not. A transition process may occur when the cooperator is waiting before the intersection. The critical value of waiting time follows the Weibull distribution. One transition regime is found in the phase diagram. The simulation results illustrate the applicability of the proposed model and reveal a number of interesting insights into the intersection management, including that the existence of defectors is benefit for the capacity of intersection, but also reduce the safety of intersection.
