According to the extensive literature,many factors affect the stock market by either direct way or indirect way.This study aims to investigate the adverse impacts of fiscal policy and monetary policies on stock market in Mongolia by using monthly data over the period January 2003 to December 2017 and applying a vector-autoregressive(VAR)model,with the predictions that fiscal crowding-out effect and too high policy rate would lower the stock price and stocks traded value.The empirical analysis in this study indicates that stock price and stocks traded value respond negatively to the shocks of policy rate and government securities traded value,respectively.In other words,the accumulated government debt and too high policy rate have crowded out the private investments in stock market and lowered the stock price by increasing riskiness of stocks or reducing the firms’net worth,which is consistent with the main predictions of this study.Therefore,to enhance the contribution of stock market for sustainable economic growth,government and authorities need to engage in implementing macro prudent and sound economic policies from the long-term perspective.When government securities are considered as a fiscal policy tool,it is significant for government to reduce the accumulated government debt and obtain the normalization of domestic bond yield through improving tax-based financing rather than government debt financing.Regarding the monetary policy,it is crucial to obtain the benchmark policy rate among Asian economies with addressing significant factors affecting the high policy rate including macroeconomic condition,balance of payment,exchange rate fluctuations,financial intermediation,and deposit holders base. 展开更多

In this paper, a policy iteration-based Q-learning algorithm is proposed to solve infinite horizon linear nonzero-sum quadratic differential games with completely unknown dynamics. The Q-learning algorithm, which employs off-policy reinforcement learning(RL), can learn the Nash equilibrium and the corresponding value functions online, using the data sets generated by behavior policies. First, we prove equivalence between the proposed off-policy Q-learning algorithm and an offline PI algorithm by selecting specific initially admissible polices that can be learned online. Then, the convergence of the off-policy Qlearning algorithm is proved under a mild rank condition that can be easily met by injecting appropriate probing noises into behavior policies. The generated data sets can be repeatedly used during the learning process, which is computationally effective. The simulation results demonstrate the effectiveness of the proposed Q-learning algorithm. 展开更多

It is a basic national policy of China and the most important problem in the current development process to control pollution and protect environment.Since environmental and ecological management has strong externality,there is little room for the private sector to play,and government governance becomes the most important means.To rationally assess government effectiveness in ecological management and clarify the main factors affecting the effective governance,Zhengzhou City is taken as research object.By referring to advanced experience of policy evaluation at home and abroad,two level-one indexes(ecological effect and economic effect)and eight level-two indexes(days of good air,concentrations of main air pollutants,energy consumption of per unit GDP,total energy consumption,per capita GDP,energy consumption of heavy industry,added value of industries above designated size,and annual fixed asset investment)are constructed to evaluate effectiveness of air pollution control policy in Zhengzhou City.Moreover,the factors affecting effectiveness of air pollution control policy in Zhengzhou City are analyzed.Finally,corresponding suggestions are proposed based on these factors:perfecting laws and regulations of air pollution control in Zhengzhou City,establishing accountability mechanism and cross regional governance system,adjusting industry and energy structure,valuing environmental technology and social participation,and improving government and people's awareness of environmental protection. 展开更多

Society needs a basis for decisions regarding market interventions. This study identifies, quantifies and values the benefits and costs of autonomous trucks and cars considering generalized costs, external effects and social marginal cost pricing to consumers with Swedish data. The results show that the greatest benefits are saved driver costs for trucks and decreased travel time costs for car drivers. In the example calculations, capital costs may increase by 22 percent for cars and 36 percent for trucks for benefits to exceed costs in 2025. Subsidies are not needed since the producers and consumers get the major benefits and pay the costs. 展开更多

A model-based offline policy iteration(PI) algorithm and a model-free online Q-learning algorithm are proposed for solving fully cooperative linear quadratic dynamic games. The PI-based adaptive Q-learning method can learn the feedback Nash equilibrium online using the state samples generated by behavior policies, without sending inquiries to the system model. Unlike the existing Q-learning methods, this novel Q-learning algorithm executes both policy evaluation and policy improvement in an adaptive manner.We prove the convergence of the offline PI algorithm by proving its equivalence to Newton’s method while solving the game algebraic Riccati equation(GARE). Furthermore, we prove that the proposed Q-learning method will converge to the Nash equilibrium under a small learning rate if the method satisfies certain persistence of excitation conditions, which can be easily met by suitable behavior policies. Our simulation results demonstrate the good performance of the proposed online adaptive Q-learning algorithm. 展开更多

New non-volatile memory (NVM)technologies are expected to replace main memory DRAM (dynamic random access memory)in the near future.NAND flash technological breakthroughs have enabled wide adoption of solid state drives (SSDs)in storage systems.However,flash-based SSDs,by nature,cannot avoid low endurance problems because each cell only allows a limited number of erasures.This can give rise to critical SSD reliability issues.Since many SSD write operations eventually cause many SSD erase operations,reducing SSD write traffic plays a crucial role in SSD reliability. This paper proposes two NVM-based buffer cache policies which can work together in different layers to maximally reduce SSD write traffic:a main memory buffer cache design named Hierarchical Adaptive Replacement Cache (H-ARC)and an internal SSD write buffer design named Write Traffic Reduction Buffer (WRB).H-ARC considers four factors (dirty,clean, recency,and frequency)to reduce write traffic and improve cache hit ratios in the host.WRB reduces block erasures and write traffic further inside an SSD by effectively exploiting temporal and spatial localities.These two comprehensive schemes significantly reduce total SSD write traffic at each different layer (i.e.,host and SSD)by up to 3x.Consequently,they help extend SSD lifespan without system performance degradation. 展开更多

Since 2000, China’s urban land has expanded at a dramatic speed because of the country’s rapid urbanization. The country has been experiencing unbalanced development between rural and urban areas, causing serious challenges such as agricultural security and land resources waste. Effectively evaluating the driving factors of urban land growth is essential for improving efficient land use management and sustainable urban development. This study established a principal component regression model based on eight indicators to identify their influences on urban land growth in Guangzhou. The results provided a grouping analysis of the driving factors, and found that economic growth, urban population, and transportation development are the driving forces of urban land growth of Guangzhou, while the tertiary industry has an opposite effect. The findings led to further suggestions and recommendations for urban sustainable development. Hence, local governments should design relevant policies for achieving the rational development of urban land use and strategic planning on urban sustainable development. 展开更多
