Replacement Investment: Optimal Economic Life Under Uncertainty

Replacement investment is essentially a regenerative optimal stopping problem; that is, the key decision concerns when to terminate the life of existing plant – and hence when to start over again. This paper examines this optimisation problem within a continuous time framework and studies the qualitative and quantitative impact of uncertainty on the timing of new investment (and the criteria that should be used for terminating the life of existing plant).     

Foreign debt and economic growth

This paper empirically examines the relationship between government foreign debt and the growth rate of per capita GDP based on a total sample of 77 countries, as well as sub‐samples of various regions. Cross‐sectional estimates of the coefficient of foreign debt based on the total sample have a negative sign, but are not always statistically significant. Available data from African countries indicate that foreign debt and the growth rate of per capita GDP were negatively related at a high level of significance. For industrialized and Latin American sub‐samples, this relationship is negative but statistically insignificant. The sub‐sample Asian and other developing countries show a positive but insignificant relationship. JEL classification: F34, H6, O23.     

欧债危机的根源及对策分析——基于最优货币区内生性理论

根据最优货币区内生性理论,加入最优货币区的决定取决于一体化、对称性和劳动力市场弹性三种内生性。美国次贷危机导致欧元区对称性下降,金融一体化、劳动力市场弹性不足和财政转移支付等补偿机制的缺失,使得欧元区未能形成最优货币区。欧元区必须通过要素市场改革和推进财政一体化等措施,才能走出困境。     

俄罗斯人口与移民状况

20世纪末21世纪初,俄罗斯爆发了第四次人口危机,这次人口危机发生在和平年代,人口出生率小于人口死亡率,俄罗斯每年减少近100万人口。由于＂缺人＂,许多村庄荒芜,大量工作无人干,西伯利亚和远东的开发也是纸上谈兵。俄罗斯政府若再不考虑从国外移民,国家将面临＂无人为继＂的尴尬局面。从＂外来移民计划＂、＂优秀人才向外移民严重＂、＂外国劳工人数下降＂和＂中国威胁论＂四个方面论述了俄罗斯人口与移民状况,说明必须增加外来高素质移民来抵消人口危机给俄罗斯的经济社会发展带来的负面影响。     

Inequality and Income Distribution in Global Value Chains

Global value chains (GVCs), led by transnational corporations (TNCs), have reshaped the world division of labor over the past two decades. GVCs are pervasive in low technology manufacturing, such as textile and apparel, as well as in more advanced industries like automobiles, electronics, and machines. This hierarchical division of labor generates wild competition at the lower value-added stages of production, where low wages and low profit margins prevail for workers and contract manufacturers in developing countries. At the top of the hierarchy another kind of competition prevails, centered on the ability to monitor and control intellectual property rights related to innovation, finance, and marketing. We argue that GVCs have had crucial effects on income inequality and the appropriation of rents in modern capitalism.
