Social cycling and conditional responses in the Rock-Paper-Scissors game

Abstract: How humans make decisions in non-cooperative strategic interactions is a big question. For the fundamental Rock-Paper-Scissors (RPS) model game system, classic Nash equilibrium (NE) theory predicts that players randomize completely their action choices to avoid being exploited, while evolutionary game theory of bounded rationality in general predicts persistent cyclic motions, especially in finite populations. However as empirical studies have been relatively sparse, it is still a controversial issue as to which theoretical framework is more appropriate to describe decision-making of human subjects. Here we observe population-level persistent cyclic motions in a laboratory experiment of the discrete-time iterated RPS game under the traditional random pairwise-matching protocol. This collective behavior contradicts with the NE theory but is quantitatively explained, without any adjustable parameter, by a microscopic model of win-lose-tie conditional response. Theoretical calculations suggest that if all players adopt the same optimized conditional response strategy, their accumulated payoff will be much higher than the reference value of the NE mixed strategy. Our work demonstrates the feasibility of understanding human competition behaviors from the angle of non-equilibrium statistical physics.

Political Connections and Industrial Pollution: Evidence Based on State Ownership and Environmental Levies in China

Abstract: We investigate how state involvement in the ownership of non-listed entrepreneurial firms affects pollution fees levied by national and provincial governments in China (environmental levies). While the national government sets minimum environmental standards, provincial governments can enact requirements that exceed these minimums, and they are largely responsible for enforcing even the national standards, so environmental levies can measure concessions that provinces make to encourage development and employment. Furthermore, state ownership is a good proxy for a firm’s political connections, which can influence the relationship between the firm and the environmental authorities. We find that firms with state ownership pay lower environmental levies, which indicates that concessions are made for political or economic purposes. However, these concessions are conditional on the level of development of the province offering them, with better developed provinces providing fewer concessions.

Modeling Plasma-based CO2 and CH4 Conversion in Mixtures with N2, O2, and H2O: The Bigger Plasma Chemistry Picture

Abstract: Because of the unique properties of plasma technology, its use in gas conversion applications is gaining significant interest around the globe. Plasma-based CO2 and CH4 conversion has become a major research area. Many investigations have already been performed regarding the single-component gases, that is, CO2 splitting and CH4 reforming, as well as for two-component mixtures, that is, dry reforming of methane (CO2/CH4), partial oxidation of methane (CH4/O2), artificial photosynthesis (CO2/H2O), CO2 hydrogenation (CO2/H2), and even first steps toward the influence of N2 impurities have been taken, that is, CO2/N2 and CH4/N2. In this Feature Article we briefly discuss the advances made in literature for these different steps from a plasma chemistry modeling point of view. Subsequently, we present a comprehensive plasma chemistry set, combining the knowledge gathered in this field so far and supported with extensive experimental data. This set can be used for chemical kinetics plasma modeling for all possi...
