This paper studies mixed models of saving with three types of risks: labor income risk, interest rate risk, and background risk. Each risk can be probabilistically modeled by a random variable or possibilistically modeled by a fuzzy number. For each model a notion of precautionary saving is defined in order to measure the effect that various types of risk have on optimal saving. The main results establish...
Goal Programming (GP) is a relevant and simple technique in Operations Research that helps Decision Makers in solving problems involving conflicting and competing criteria and objectives. A GP program is a distance-based model that involves the minimization of the difference between the achievement level of a certain criterion and its goal. GP models when combined with the notion of satisfaction or...
Description of a methodology for selecting appropriate technologies for constructing telecommunication access networks in the conditions of a specific locality is given. The methodology is used to select appropriate technologies for constructing the access networks of Ukraine's largest telecommunications operator (Ukrtelecom). Methodology may be useful for network owners (or designers) as a basis...
The development of modern services cannot do without the staffs in this field. As the global industry transfers from industrial economy to service economy, the labor demand for modern services keeps increasing. The research reviews labor demand theories and its various incidence impacts, and carries out forecast research and incidence research of the number of people engaged in services in the future...
Reduction in the number of recessions have started a new concept known as Dynamic Risk Overlay concept. It was initiated after rise in overall systematic risks. We have proposed different methods that can be used as a source to provide hedging strategies in case of risks. VAR calculations are an important aspect to be considered while assessing the risks that a portfolio might encounter. We have implemented...
This contribution discusses the concept of stochastic controllability within the framework of linear interest rate models of Heath-Jarrow-Morton-Musiela (HJMM) type that may be represented by an infinite dimensional stochastic differential equation. Despite the fact that not all such models are controllable, we nonetheless investigate the possibility of influencing the drift term of the aforementioned...
This paper presents an economic analysis of solar chimney power plant (SCPP) of 200 MW capacity in India by taking fifteen different sets of dimensions of chimney height and collector diameter, five sets each corresponding to collector efficiency of 33%, 50% and 65%. Quantity of different materials required and capital cost for construction of 200 MW solar chimney power plant is estimated. Based on...
Many policy and national security challenges require understanding the social, cultural, and economic characteristics of a country or region. Addressing failing states, insurgencies, terrorist threats, societal change, and support for military operations require a detailed understanding of the local population. Information about the state of the economy, levels of community support and involvement,...
There are many factors that affect shipbuilding market demand. The paper analysis the internal and external environment of shipbuilding market first. Then, it ranks the influence degree by using the grey relevant method. And it builds influence models with ridge regression method, so as to describe the trends of the shipbuilding market demand.
In this paper, the author uses the modern econometric methods by panel unit root test, cointegration test and random effects models, and the data of FDI (2000–2011), urbanization rate, industrial structure and regional GDP of Nanjing, Xuzhou, Suzhou, Wuxi and other 13 cities of Jiangsu Province, researches the relationship between FDI and urbanization rate. Model shows, FDI was closely correlated...
Urbanization is the integrated symbol for levels of economic development and social modernization. This paper analyzes the urbanization dynamic mechanism, maintains the idea that the initial, fundamental and subsequent dynamic mechanism driving modernization are the development of the primary, secondary and tertiary industries respectively. On these bases, this paper establishes relevant error correction...
A variety of fractional order models have been proposed in the literature to account for the behaviour of financial processes from different points of view. The objective of this work is to model the growth of national economies, namely, their gross domestic products (GDPs), by means of a fractional order approach. The particular case of Portugal is addressed, and results show that fractional models...
This project examines the Sustainability and Systemic Risk Index (SSRI) as a new macroeconomic index for the United States banking industry. The SSRI measures the aggregate level of risk across all federally insured banks and indicates the industry's sensitivity to systemic events. Since the 2008 recession, the government and the public have searched for ways to analyze elevated levels of risk to...
Despite the increased focus on making energy more efficient, research has rarely examined the temporal impact of energy efficiency on environmental performance at the national level. Using archival data, we conduct an econometric analysis that provides empirical evidence indicating the negative effects of the rebound effect and the positive effects of technology. Our results suggest that an increase...
In this paper, dynamic analysis of Beijing water resources management is studied by forecasting method. First, the condition of water resources of Beijing is introduced. Second, the model of the water resources forecasting in Beijing is constructed from two aspects, i.e., supply side and demand side. Finally, some management insights and suggestions are presented based on the dynamic analysis.
This study aims to model the characteristics of volatility of the exchange rate of the Chinese Yuan, based on the daily data of CNY and CNH over the period from August 23, 2010 to September 10, 2013, in the backdrop of RMB internationalization. By introducing both symmetric and asymmetric models of the generalized autoregressive conditional heteroscedastic (GARCH) family, we use the daily data to...
In this study, various models are used to forecast oil barrel price (OBP) in Saudi Arabia using artificial neural networks (ANNs). The proposed models are based on a multilayer feedforward neural network with backpropagation (MFFNNBP). A number of features were used as inputs to the neural network, such as gross domestic product (GDP), inflation rate, and unemployment rate. The results show that,...
This paper tries to study the effect of real estate regulation policies longitudinally since China's housing system reform from the year 1998 from microscopic perspective. We established four Cox models, in which the time interval between interviewee's first job to his/her first homeownership was considered as the survival time; the monetary policies, tax policies, land policies and individual's social...
The sustainable development of western economy is inseparable from the strong support of energy and environment system. This paper researchs 11 provinces, cities and autonomous regions in western China and creates a simulation model of petroleum-environment-economy system by the method of SD. The simulation model shows the basic model and the rapid model oriented by pursuing economy growth are not...
