Today, they have become large retailers capable of influencing local development from an economic, social and urban perspective. The literature concerned with their effects on the local economy has focused on labour markets, price dynamics, and inter-type competition, neglecting their impact on macroeconomic factors such as GDP, value added specific sectors--agriculture, industry and services. This study tries to contribute to fill this gap by empirically investigating associations between key characteristics of these retailers and specific macroeconomic value added factors展开更多

We use an original information risk model to contribute to the analysis of the crisis and to suggest some approaches for a possible early diagnosis. Using data referred to the three main financial markets and comparing the latest crisis with the previous one and with long-term quantitative evidence, we find out that the 2007-2009 crisis was very different in the information risk quality. That gap affected the market risk aversion and its equilibrium, reducing the efficacy of the authorities＇ intervention tools mainly based on payoff risk control and efficient market restoration. Since information risk is an endogenous element of the market dynamics that can be independent form contingent levels of market efficiency. Drivers of information risk in the European Markets differed strongly from the US and Japanese ones; that is why some global decisions had low impact while opportunities of local intervention were missed.展开更多

Externalities interacts with the agglomeration of productive factors. Under the framework of new economic geography, this article presents a theoretical model involving the endogenous population density affected by urban externalities. Results show that the population density is more concentrated around the center because the degree and extent of interaction between individuals intensifies when the distance from the center decreases. When there are several externalities resources, the aggregation of externalities changes the configuration of spatial factor allocation. These results fit well with the empirical facts about the decreasing density of floating population along the cities of Guangzhou, Dongguan and Shenzhen in Guangdong Province which is situated in the eastern coast of the Pearl River Delta. We fred that under the impacts of externalities released from Hong Kong into the coast, floating population was more concentrated around Shenzhen and Dongguan, which are more adjacent to Hong Kong compared with Guangzhou City.展开更多

In the critical time of China facing population aging and economic transformation, as the new human capital of the labor market, college students play an important role to social and economic development. Therefore, preventing and mitigating their human capital depreciation is necessary. This article focus on human capital investment and configuration stage, analyze the influence of unreasonable human capital investment system and separate labor market segmentation system to college student human capital depreciation, and put forword the corresponding countermeasures.展开更多

The pessimistic expectations of entrepreneurs concerning product demand leads to falling direct investment into business despite unlimited investment opportunities due to the developed capital markets nowadays. As a result it has created the opportunity for the development of such business restructuring types as mergers and acquisitions. Potential investors are different and their investment motivation is different, but the goal is the same--to increase the value of the business and its efficiency as a result of mergers and acquisitions. Utilizing borrowed capital for acquisitions of enterprises has many advantages. However, purchasable enterprises are exposed to several financial risk factors.展开更多

In the simulation, the genetic algorithm is used to generate the next generation products and a dynamic social impact model is used to simulate how customers are influenced by other customers. The simulation and its results not only show some features and patterns of knowledge transition, but also explore and display some phenomena of business cultures. On the basis of the innovation model of knowledge-based economy, the transition between technical knowledge and products knowledge is discussed, and a fuzzy linear quantification model which can be used to simulate the transition is introduced.展开更多
