Domestic Support and Border Measures for Processed Horticultural Products

In horticultural markets, trade barriers often apply to the processed products whereas domestic support applies to farm-produced raw commodities. Here we assess the effects of such trade barriers and domestic support by simulating the effects of policy reform on global processing tomato markets, which are faced with modest processed product tariffs and high domestic support in the European Union (EU). Both protection and EU subsidy drive down world welfare, but we find that reducing import tariffs for tomato products would yield greater effects on markets and larger welfare impacts outside Europe than would reductions in EU domestic support.     

Bureaucratic integration and regional specialization in China

Fiscal decentralization introduced as part of China's economic reform since 1979 has unleashed strong incentives for China's local governments to pursue economic development, but the same incentives have also led to local protectionist policies inhibiting the process of regional specialization. This paper focuses on the constraints or freedom with which local governments can implement their protectionist policies. Using a panel data of 29 China's regions over the time period of 1985–1997, we find that China's political system of bureaucratic integration (specifically, concurrent appointment of local government officials in the central government) imposes constraints on the local governments from practicing protectionism. We also find that the effectiveness of local protectionist policies is limited by market competition, specifically, competition from foreign-invested firms operating in China and foreign imports. Our results on the role of local protectionism remain robust to controls for the regional variations in the size of the economy and the stage of economic development.     

Research on principal-agency of stockholders and managers under asymmetric information condition

In modem enterprises, a separation of the right of ownership and management results in asymmetric information problems between stockholders and managers. In conditions of principal-agency relationship, the game behaviors between principle and agency within enterprises are impacted by asymmetric information. This study discusses the game behaviors between stockholders and managers by using information economic theories from the perspective of asymmetric information. Based on the model of the principal-agency relationship between stockholders and managers, our research uses quantitative analysis to reveal how to achieve maximum profit expected of stockholders through an incomplete contract, under asymmetric information condition.     

蒙代尔-弗莱明模型在发展中大国的适用与延伸

M-F模型是开放经济宏观经济学的基本模型,其存在的缺陷和局限是理论拓展的主要方向。本文对M-F模型的前提假定和分析过程作出了放松和修正,使其适用于发展中大国的情形。并在M-F模型的货币政策效应分析基础上,提出M-F模型在发展中大国的延伸分析方法,即Semi-M-F模型分析方法,指出发展中大国的货币政策是部分起作用的。最后,对Semi-M-F模型分析方法在中国的应用进行评述。     

基于引力模型的中美农产品贸易边境效应研究

针对中美两国在农产品贸易上的新变化,应用引力模型的派生模型——边境效应引力模型对中美两国农产品贸易的流量和流向进行理论和实证研究。首先介绍了边境效应引力模型基本模型的推导过程,并引入了调整模型。然后采用1987至2005年其中5年的截面数据进行计算,结果发现:中美农产品贸易的边境效应显著存在,且呈逐年下降趋势;两国之间的农产品贸易边境效应存在流向和区域上的差异;距离的平方并不影响模型的可靠性。

窄岭金矿剪切带基本特征与发展演化模式

河北丰宁窄岭金矿,可以区分3幕Ⅰ级韧性剪切带,1幕Ⅱ级脆韧性剪切带和1幕Ⅲ级脆性剪切带。伴随不同的剪切变形变质作用,分别有花岗岩(红旗菅子群花岗片麻岩)→闪长岩(变闪长岩)→正长斑岩→含金石英脉的侵位。而金矿则是这种多期多阶段构造—岩浆复杂演化使金逐步富集的最终产物。
