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.

The institution efficiency of stock price limits： An experimental analysis on the two stocks market with continuous bid

Price limits in product market have been discarded in classic microeconomics. However, price limits affect the trade behavior of the same agent, since agents in the stock market change their trade status frequently. Due to the controversy on the institution effectiveness of the price limits in stock market, this paper design an experimental market with two stocks with continuous bid, in which we investigate the impact of the price limits on the stock market. The results show that the price limits moderate the price volatility within and between the trades periods, thus can stabilize stock price. In addition, price limits, when measured by traditional approach, restrain the fluidity of the market, reduce the volatility of transaction shares and maintain durative of fluidity. While volatility-based fluidity measurements show that the fluidity is enhanced significantly in stock market with price limits.
