What drives the growth of shadow banks? Evidence from emerging markets

The present study analyses the factors affecting the growth of Non-Banking Financial Institutions (NBFI) and finance companies in 11 emerging market economies (EMEs) that the FSB monitors. Using data for the period 2002 to 2019 and employing the panel corrected standard errors (PCSE) method, the results indicate that the growth of banks, search for yield, demand from institutional investors, and bank regulations are the key factors affecting the growth of NBFI.Further, the study highlights the impact of different types of bank regulations on the NBFI growth in EMEs. While the capital regulations tend to restrict their growth, activity restrictions and restrictions for financial conglomerates boost NBFI growth. Thus, stringent bank regulations create arbitrage opportunities for non-banks.     

IPV6在智能家居中的应用探析

IPV6是IETF设计的用于替代现行版本IP协议（IPV4）的下一代IP协议,它在构建家庭智能化网络方面真有诸多优势。智能化家居能够向人们提供方便快捷的信息通信、高效便利的物业管理、高效节能的建筑设备及安全舒适的人居环境．本文在介绍IPV6及智能化相关技术基础上,对IPV6在智能家居网络建设中的应用进行了探索性的分析阐述。     

Inflation and inequality

Cross-country evidence on inflation and income inequality suggests that they are positively related. This article explores the hypothesis that this correlation is the outcome of a distributional conflict underlying the determination of government policies. A political economy model is presented in which equilibrium inflation is positively related to the degree of inequality in income due to the relative vulnerability to inflation of low income households.     

Apply 6-sigma methodology in measuring the competition quality of satisfaction performance—an example of ISP Industry

At present time the ISP (Internet Service Provider) already make a great impact to the human life as well as the economic society, everything has a close relation with the internet service and due to the fast development of information technology further lower the cost of ISP and improved the service speed as well as its quality. All of this make the customer layer of ISP more popular than before and thus bring up the fierce competition in this industry. Due to the entry barrier of high investment and high technology of ISP industry it has become as a monopoly market and the monopoly market is very respect the competition and cooperation relationship with competitors. Besides, most of the relevant literature in the past is focus on the measurement and analysis of customer to the self-company and few of them mention how to include the satisfaction of competitor’s customer into measurement and analysis. As golden strategy stated in the Sun-Tze Strategic: “Know yourself and know your competitor well, winning every war.” we must consider the strength, weakness, opportunity and threat on customer satisfaction of your company and competitors. Base on the above motivation, this article will apply the DMAIC (Define, Measure, Analyze, Improve, Control) methodology of 6-Sigma, focus on the viewpoint of customer satisfaction of ISP industry. At first we utilize the 5 equal scale measurement define the network quality item of ISP, which provided by the self-company and competitors. And measuring the degree of “satisfaction” and “importance” of these quality items, then use the performance evaluation matrix and strength and weakness matrix to analyze the Strength, Weakness, Opportunity and Threat of self and competitors, focus on the quality items that fall out of the 2 sigma and use the strength–weakness strategic chart to establish the improvement strategy. And at last, utilize the strength–weakness matrix chart as the control tool to verify and sustain the effectiveness of the improved performance. The complete and easy measurement improvement model provided in this article can be used by the enterprise to effectively and quickly evaluating and analyzing the service quality of self and competitors. And under the reasonable cost condition with considering the competing opportunity and threat of market to effectively improving the customer service quality and promoting the overall customer satisfaction and create powerful high value-added quality competition strength.

The European Union's debt question: A conceptional viewpoint

The state can be conceived as an organization to protect personal freedom and to provide public goods. Consequently, we expect a constitution to consist of two different sets of rules; rules on personal freedom and rules for making collective decisions on public goods (mostly budgetary rules). The constitution of the European Union as laid down in the treaty of Maastricht (1992) provides both types of rules, but the emphasis is mainly on the former rules. This paper investigates budgetary rules, in particular the welfare economic logic of deficit spending.     

Labor market rigidity and productivity growth in a model of innovation-driven growth

Empirical studies investigating the relationship between productivity performance and labor market rigidity have generated a negative result. In this paper we try to provide a theoretical explanation for this empirical result. In doing so, we construct a no-shirking model of innovation-based growth and investigate the steady-state impact of a set of active labor market policies aimed at reducing labor market rigidity and knowledge mismatch generated by innovations. We find that, while enhancing job finding activity definitively improves the equilibrium growth-unemployment mix of the economy, reducing the knowledge mismatch of innovation through active measures is less effective in reducing the equilibrium unemployment and improving growth.
