We not only introduce a new concept of distributional fairness degree, but also obtain the cooperation conditions for overcoming dilemma in terms of fairness and entanglement inequalities. It is demonstrated that distributional fairness can be of fundamental importance to promote cooperation with the help of quantum entanglement.展开更多

First, this paper describes the change in income gaps before and after reform and opening-up in 1978 and found that income gaps had been expanding between urban and rural areas, within cities and within the countryside. However, this did not lead to income polarization since low-income groups only had a slower income growth compared with highincome groups. The number of poor people continuously reduced thanks to rapid economic growth. Over the past decade, the widening of income gaps has been initially curbed. Accordingly, we explained the impact of economic transition on income distribution from the perspectives of market-based distribution, ownership structure, opening-up and internal income distribution. Lastly, this paper provides an in-depth analysis on urban-rural income gaps, excessive compensation in monopolistic sectors and income inequalities arising from corruption. To address these problems, it is important to enhance tax regulation, increase transfer payments to poor people, improve social security, equalize public services, enhance poverty relief and develop a fairer income distribution system.展开更多

The present paper aims to investigate the link between absolute pay level and pay level satisfaction by introducing both distributive and procedural fairness perceptions as mediators in accordance with fairness heuristic perspective. A sample of 298 employees from various types of organizations completed a survey, and a series of models were compared to evaluate if the hypothesized theoretical model fits our data. We also constructed bias-corrected bootstrap confidence intervals to test the hypothesized mediation effects. The suggested theoretical model is supported, and future research directions are discussed.展开更多

文摘We explore the impact of distributional fairness degree and entanglement degree on the cooperation between different players by investigating a modified prisoner's dilemma game. We not only introduce a new concept of distributional fairness degree, but also obtain the cooperation conditions for overcoming dilemma in terms of fairness and entanglement inequalities.
