东亚货币合作可行性的经济数据检验——基于OCA理论的分析

在最优货币区理论构筑的分析框架下,东亚区域在经济开放度、出口产品结构相似性、经济冲击对称性方面达到了OCA理论的标准,而在生产要素的流动性、金融市场一体化等方面距离最优货币区的标准尚有差距,但是这种差距正在缩小。通货膨胀相似性方面东亚整体虽未满足OCA标准的要求,但是有次区域已经符合这一标准。考虑到最优货币区标准的内生性,而且大量文献通过对东亚地区进行分组并采用不同的研究方法,证明东亚地区存在形成最优货币区的潜力,因而对次区域的货币合作可行性分析依然乐观。     

基于GIS的成都经济区区域合作层次划分研究

以成都经济区为研究对象,采用SPSS因子分析法和GIS空间分析方法,选择GDP、人均GDP、经济密度、财政收入、社会固定资产投资、工业增加值、城市化率、工业化率八个指标,对成都经济区所辖八市的综合经济水平进行定量分析和空间分析,并结合八市之间的经济距离,应用城市引力模型,测算了成都市对成都经济区其余各市的辐射影响力,基于此得出,成都经济区区域合作分三个层次：首先,成都与德阳、绵阳（1＋2）;其次,成都、德阳、绵阳、眉山、资阳（3＋2）;最后,整个成都经济区八市（5＋3）。

Gold dinar for the Islamic countries?

The Malaysian state of Kelantan has made a historical launch of Gold Dinar and Silver Dirham on 12th August 2010. For the first time in almost 100 years since the fall of the Ottoman Caliphate, a Muslim government introduces Shariah currency. In the eyes of many Muslim scholars, the present interest-based fiat monetary system is flawed as it is incompatible with the objectives of the Islamic law or the Shariah. There have been calls for the resurgence of Islamic Gold Dinar (together with the silver dirham) as it is deemed to be the most appropriate medium of exchange to be used in the Islamic economies. Using data from 1970 to 2007, this paper assesses the empirical desirability of the Organization of Islamic Conferences (OIC) countries to an alternative monetary system (Islamic Gold Dinar) that can potentially enhance the exchange rate stability and credibility. The Structural Vector Autoregression (VAR) method is employed to assess the nature of macroeconomic disturbances among the OIC countries. Specifically, the symmetry in macroeconomic disturbances of the OIC economies is examined as satisfying one of the preconditions for forming an Optimum Currency Area (OCA). In addition, this paper also investigates the output and price responses of OIC countries of the underlying structural shocks used to shed light on the suitability of these countries to form a monetary union. The preliminary findings of this study suggest the lack of broad linkages within the entire OIC, although there exists scope among some smaller clusters for potential monetary integration based on the symmetry of their business cycles.     

Trust, reputation and relationships in grazing rights markets: An experimental economic study

Trust is frequently a requirement for economic exchanges and the management of natural resources. Providing public information on past actions can promote trust through the formation of reputations. We developed an economic experiment to test whether a formal reputation mechanism could facilitate trusting relationships in the tradable grazing rights markets. Providing information to create formal public reputations for market participants did not increase the overall efficiency of the market. However, it did result in greater equality of income between partners, suggesting that participants showed more concern for their partners when they knew they would be rated. Even with public reputation information, bilateral relationships remained central to the market. Market failures in existing grazing rights markets may be better addressed by measures to increase communication between partners rather than simply relying on a formal reputation mechanism.
