Prices and factor demand in an endogenized input–output model

This paper combines factor demand functions (for intermediate input and labour) and price equations (derived from a Generalized Leontief cost function) with the traditional input–output price model. The cost functions determine factor demands for materials and labour as well as output prices at given input prices. At the second level of aggregation, the intermediate demand as a single input is split proportional to the elements in the column of the technical coefficients matrix. The emphasis in this endogenization of technical coefficients is on two features. First, the repercussion of output on input prices, and, second, the link between the econometric model for the supply side and the input–output demand model.

一种新的顾客满意度指数测评模型

顾客满意度指数是近年来许多国家和地区积极开展研究和采用的一种新的经济指标。本文在已有研究的基础上,结合我国消费者行为的特点,构建了一种新的顾客满意度指数测评模型。该模型在期望不一致模式的基础上,同时考虑了公平模式和需要不一致模式,引入感知公平和感知价格变量,并为这些结构变量设计了相应的观测变量和路径关系,建立了由顾客满意、企业形象、感知价格到顾客忠诚三条路径关系,改变了传统模型中从顾客满意到顾客忠诚路径过于单一的情况。

TS模糊模型在个股股价预测中的应用研究

个股价格短期内的变化量一般可通过股票技术指标间接反映出来,且这些指标间有着一定的相关性;另外,股票价格模型具有Takagi-Sugeno(TS)模糊模型所研究问题的非线性、时变性特点,基于此,本研究将TS模糊模型与分析出的股票常用技术指标相结合进行股价预测。结果显示预测出的价格与股票实际价格近似一致,精度高,因此研究具有一定的实用价值。

The Price Effect on Spatial Structure: Revisiting the New Economic Geography Model

Abstract

This paper adds a factor of production, land, to the standard core-periphery model of the New Economic Geography to analyse the effect of land rent on the price index and spatial structure. The result indicates that when production of the manufacturing sector has high dependence on land, and high demand elasticity for differentiated goods, the price index of the core region is higher than that of the periphery, and that the price index could rise with a degree of agglomeration. Meanwhile, the market forces cannot generate a core-periphery structure, which indicates the significance of the price effect on spatial structure.     

Enterprise systems in financial sector – an application in precious metal trading forecasting

The use of enterprise systems has become increasingly popular in the financial service industry. This paper discusses the applications of enterprise systems in the financial sectors and presents an application in gold price forecasting. We carefully examine the impacts of a few most widely assumed factors that have significant impact on the long-term gold price using statistical regression techniques. The analysis on our proposed linear regression mode indicates that the United States ultra scale of M2 money supply has been the most important catalyst for the rising price of gold, and the CRB index upward trend has also been the weighty factor for pushing up the gold price. In addition, the gold price has a low negative correlation with the Dow Jones Industrial Average, and low positive correlations with the US dollar index and the gold ETFs holdings.     

Asset price,risk transfer and economic activities: Firm-level evidence from China

The paper investigates the extent of the impact from changes in asset price and risk on corporate investment behaviors as well as the real economy. The results support the unidirectional causality effects from asset price fluctuations on the macro-level. By applying quarterly data of Chinese listed companies, we further find the existence of balance sheet effect on the firm-level, which suggests that the changes in asset prices and risk affect the net asset value, and consequently influence corporate investment decisions. More importantly, the balance sheet effect appears to be much more significant after the implementation of new fair value accounting standards in 2007. The impact on the real economy from asset price risk is found to be more prominent as well.
