1995年11月,驻津巴布韦大使任期刚刚结束后,我又奉命担任南非研究中心主任。该中心是中国政府根据与南非政府所达成的协议,在南非设立的常驻机构,办公地点在南非的行政首都比勒陀利亚(南非有行政、立法、司法三个首都,分别是比勒陀利亚、开普敦、布隆方丹)。 相似文献

纳尔逊·曼德拉逝世的消息传遍全世界,也引发了各种纪念和评论。不同价值立场的人各取所需:在有些人眼里,他是自由偶像和人权斗士;而在另一些人眼里,他是反帝反殖民的民族主义英雄。早在毛泽东、周恩来时代,他就是“中国人民的老朋友”,后来又直接促成了南非与中国的正式建交。 相似文献

自改革开放以来,中国发生了翻天覆地的变化。社会生产力得到极大解放和发展,城乡居民收入水平成倍增长,物质文化生活大幅度改善,人民生活总体达到小康水平。然而,也有人感到不安甚至不满,社会不和谐现象时常可见。出现这种情况原因是多方面的,但社会公正未能真正实现是其中最重 相似文献

曼德拉说:“一个国家不应从它如何对待其高级公民来判断其好坏,而应当从它如何对待其最低级的阶层来判断其优劣。”“有许多黑暗的时刻,人道主义信仰一时经受了痛苦的考验,但是,我将不会也不可能会向悲观低头。向悲观低头就意味着失败和死亡。”“我已经发现了一个秘密,那就是,在登上一座大山之后,你会发现还有更多的山要去攀登。” 相似文献

The popular Nelson–Siegel [Nelson, C.R., Siegel, A.F., 1987. Parsimonious modeling of yield curves. Journal of Business 60, 473–489] yield curve is routinely fit to cross sections of intra-country bond yields, and Diebold–Li [Diebold, F.X., Li, C., 2006. Forecasting the term structure of government bond yields. Journal of Econometrics 130, 337–364] have recently proposed a dynamized version. In this paper we extend Diebold–Li to a global context, modeling a potentially large set of country yield curves in a framework that allows for both global and country-specific factors. In an empirical analysis of term structures of government bond yields for the Germany, Japan, the UK and the US, we find that global yield factors do indeed exist and are economically important, generally explaining significant fractions of country yield curve dynamics, with interesting differences across countries. 相似文献

We estimate versions of the Nelson–Siegel model of the yield curve of US government bonds using a Markov switching latent variable model that allows for discrete changes in the stochastic process followed by the interest rates. Our modeling approach is motivated by evidence suggesting the existence of breaks in the behavior of the US yield curve that depend, for example, on whether the economy is in a recession or a boom, or on the stance of monetary policy. Our model is parsimonious, relatively easy to estimate and flexible enough to match the changing shapes of the yield curve over time. We also derive the discrete time non‐arbitrage restrictions for the Markov switching model. We compare the forecasting performance of these models with that of the standard dynamic Nelson and Siegel model and an extension that allows the decay rate parameter to be time varying. We show that some parametrizations of our model with regime shifts outperform the single‐regime Nelson and Siegel model and other standard empirical models of the yield curve.
