Uncertainty in the Austrian Theory of Capital

This paper is based on the traditional Austrian Theory of Capital which deals with expected values of future returns of investments over various periods of time. The longer the time period that elapses between the beginning of a production process and its end, the higher the (expected) productivity must be due to positive time preferences of individuals. This paper focuses on the uncertainty of future returns and on uncertainty preferences, instead. Based on the Hayekian idea of the dispersion of knowledge in society, it will be shown that there is a systematic relationship between the structure of capital and uncertainty. This result will be derived for a production process characterized by complete vertical integration and one which is not completely vertically integrated. The distinction between these two settings is crucial, if one accepts the distinction between an individual and a social period of production and the planning horizon which are introduced in this paper.     

Cost monotonicity, consistency and minimum cost spanning tree games

We propose a new cost allocation rule for minimum cost spanning tree games. The new rule is a core selection and also satisfies cost monotonicity. We also give characterisation theorems for the new rule as well as the much-studied Bird allocation. We show that the principal difference between these two rules is in terms of their consistency properties.

国际投资税收政策对跨国企业集团投资战略的影响

由于各国经济发展水平、经济资源优势和经济国际化程度不同,各国都制定符合各自经济政策目标的国际投资税收政策,采取的税收优惠政策的侧重点也各不相同。跨国企业集团在制定投资战略时应注重分析各国引导投资的侧重点并充分加以利用,在投资战略选择中,必须慎重确定投资所在国的重点优惠项目或重点优惠地区,全面考虑投资国和投资所在国之间的国际税收协调性,正确认识资本投入量同税收负担与其他投资环境要素之间的关系。应以全球的观点进行国际化投资战略规划,以谋求集团整体税收负担的最小化和整体投资收益的最大化     

QUADRATIC TERM STRUCTURE MODELS FOR RISK-FREE AND DEFAULTABLE RATES

In this paper, quadratic term structure models (QTSMs) are analyzed and characterized in a general Markovian setting. The primary motivation for this work is to find a useful extension of the traditional QTSM, which is based on an Ornstein–Uhlenbeck (OU) state process, while maintaining the analytical tractability of the model. To accomplish this, the class of quadratic processes, consisting of those Markov state processes that yield QTSM, is introduced. The main result states that OU processes are the only conservative quadratic processes. In general, however, a quadratic potential can be added to allow QTSMs to model default risk. It is further shown that the exponent functions that are inherent in the definition of the quadratic property can be determined by a system of Riccati equations with a unique admissible parameter set. The implications of these results for modeling the term structure of risk-free and defaultable rates are discussed.

日本泡沫经济制度性原因分析及启示

20世纪90年代被称为日本经济“失去的10年”。日本经济一蹶不振,丧失了整整10年的发展。不少学者认为,90年代日本经济萧条意味着日本“又一次战败”即在经济战场上的“战败”。日本经济战败是败在了“制度”或“体制”方面,败给了成功地实行了“制度创新”或“体制创新”的美国。分析引发日本泡沫经济的制度性原因、探索日本经济走出衰退的途径,从中可寻找出对我国经济发展的有益启示。
