Evolutionary Game Analysis of Government and Residents’ Participation in Waste Separation Based on Cumulative Prospect Theory

Abstract: Government and residents’ participation in waste separation is a complex non-cooperative game process, and the evolutionary game can explain the behavior of participating subjects well. Considering that the traditional evolutionary game cannot satisfactorily explain the irrational psychology and risk preference factors of the participating issues, this study combines the prospect theory and evolutionary game, uses the prospect value function to supplement and improve the parameters of the evolutionary game payment matrix, and analyzes the evolutionary stabilization strategy. To verify the theoretical results, simulation experiments and impact analysis were conducted, and meaningful results were obtained: There are two stable evolutionary strategies in the system, namely higher participation benefits for residents and lower participation costs and opportunity costs, and reasonable direct benefit distribution coefficients all help to increase the participation rate of waste separation. This study can provide some scientific suggestions for the government to design and build a waste-separation system.

Evolutionary Game Study of Waste Separation Policy in the Context of the “Double Carbon” Target

Abstract: Research on waste separation promotion policies is of great theoretical and practical significance for the universal implementation of the domestic waste separation system. This paper constructs a non-cooperative tripartite evolutionary game model that includes central command, local deployment, and enterprise performance. An evolutionary game approach was used to analyze the strategic choices of the central government, local government, and separation enterprises in waste separation promotion, and this study investigated the factors influencing the evolution of these choices using numerical simulations. The findings indicated the following: central government, local governments, and separation enterprises are affected differently by their respective willingness to participate; the behavior of separation enterprises is less influenced by the central government’s and local governments’ willingness to participate and is primarily influenced by market factors, whereas local government is more influenced by the central government’s willingness to participate; and local government and classification enterprises are affected differently by their respective willingness to participate. While separation firms are more susceptible to the cost-sharing, income, and revenue distribution coefficient, local governments are more responsive to policy support. The promotion of waste separation in China requires strengthened centralized waste management to avoid the failure of local waste separation, broadening of the scope of central funding incentives and establishing local separation compensation mechanisms, clarifying local waste separation performance responsibilities and new waste tax collection standards, supporting separation enterprises’ technological innovation and guiding public participation in waste separation, creating an environment for waste separation, and deepening the study of waste separation accordingly.

Study on the Evolution of the Game of Willingness to Cooperate between Residents and Separation Enterprises in Waste Separation Considering the Convenience of Separation Facilities

Abstract: The distributivity and complexity of separation facilities in waste separation cooperation are incorporated into the factors influencing the payoff of waste separation cooperation. The game payment matrix of waste separation cooperation is constructed based on the distributivity and complexity of separation facilities. The equilibrium solution of waste separation cooperation is obtained through the evolutionary game. The influence of different changes in distributivity and complexity of separation facilities on the willingness to cooperate in waste separation is explored through numerical analysis of cases. The study shows that when the distributivity of separation facilities is certain, the lower the complexity of separation facilities, the higher the willingness of residents and enterprises to cooperate; when the complexity of separation facilities is certain, the willingness of residents and enterprises to cooperate rises and then falls with the increase of distributivity of separation facilities; finally, when the distributivity and complexity of separation facilities change at the same time, the willingness of residents and enterprises to cooperate shows different changes with the different changes of two separation facilities convenience factors.

Information communication technology (ICT) infrastructure and economic growth: A causality evinced by cross-country panel data

Abstract: This study examines certain long-run relationships hypothesised to be present among per capita real GDP, information and communication technology (ICT) infrastructure, consumer price index, labour force participation rate, and gross fixed capital formation manifest in G-20 countries recorded for the 2001–2012 period. Using panel cointegration, the study finds that the variables are cointegrated and do not drift apart in the long run. Methodology using vector error correction models (VECM) further confirms that embellishment of ICT infrastructure – an apparent imperative in an economy's information technology (IT) policy formulation – for both fixed broadband and internet users causes a boost in the per capita GDP.

Is the demographic dividend an education dividend

Abstract: The effect of changes in age structure on economic growth has been widely studied in the demography and population economics literature. The beneficial effect of changes in age structure after a decrease in fertility has become known as the "demographic dividend." In this article, we reassess the empirical evidence on the associations among economic growth, changes in age structure, labor force participation, and educational attainment. Using a global panel of countries, we find that after the effect of human capital dynamics is controlled for, no evidence exists that changes in age structure affect labor productivity. Our results imply that improvements in educational attainment are the key to explaining productivity and income growth and that a substantial portion of the demographic dividend is an education dividend.

Regulation, Public Policy, and Investment in Communications Infrastructure

Abstract: Regulation and other forms of public policy toward infrastructure industries were and are designed to support large-scale investment. Throughout history, with few exceptions, rather pragmatic approaches guided policies. A more rigorous lens was only applied more recently although it often focused on narrow aspects of regulation. In contrast, this paper attempts to develop a broader, integrated framework to analyze the effects of regulatory and other public policy choices on sector investment. During the past decades, regulation has gradually abandoned instruments that allowed regulators to influence investment decisions directly. Presently used forms of wholesale regulation such as unbundling and network neutrality requirements work indirectly, creating complex and sometimes contradictory incentives for the affected stakeholders. Regulation cannot anymore "control" investment. Rather it functions as a "tuning variable" that influences the level and the structure of investment activity in various direct and indirect, often non-linear ways. Fiscal and monetary policy instruments also can be used to influence investment choices but they have their own advantages and disadvantages and do not work under all conditions. Due to the multi-faceted effects of regulatory measures, fiscal and monetary policy is preferable to regulatory measures to create short term economic stimulus. Whereas the overall effects of a combination of regulatory and other public policy measures on communications sector investment levels and structure are difficult to predict, basic guidelines for the design of a coherent approach can be specified.

What drives investment in telecommunications? the role of regulation, firms' internationalization and market knowledge *

Abstract: The aim of this paper is to classify the firms operating in the European telecommunications market according to their degree of internationalization and market knowledge, and to test the effects of this classification and the existence of access regulation on infrastructure investment in European broadband markets. To do so, we construct a (unique) data set for the 27 European countries for the period 2002 to 2009. We estimate, by means of panel data techniques (and instrumental variables to control for any potential endogeneity problem), an investment equation for all firms and separate equations for entrant and incumbent firms. Our results show no significant relation between regulation and total investment. The variables capturing the degree of internationalization and market knowledge have a positive and significant effect on total investment, being a positive and significant effect on entrants' investment, but no significant impact on that of incumbent firms. This result indicates that, under the current regulatory framework, the firms that invest most are entrants with international experience, while the expansion of incumbents into other countries does not affect their investments in their home countries.
