现代火成岩岩石学的某些前沿课题及其哲学思考

本文以现代火成岩岩石学的概念为出发点,从哲学的角度讨论了现代火成岩岩石学的某些前沿课题。对岩浆作用的全面认识,不仅要研究其化学过程,还必须从物理过程去探索;地幔—岩浆—C—H一O系统的研究是深部地质研究的一个侧面,深部地质过程是地表及浅部地质现象的动力来源;超地幔热柱是板块运动和大规模岩浆活动的起因,大规模的岩浆活动及板块运动是超地幔热柱在地表或地壳浅部的直接表现;开放的岩浆体系的提出,丰富了现代火成岩岩石学的内容。     

当前人民币汇率制度选择的理论思考

任何汇率制度都只是实现经济目标的手段而不是目的,我们在各个时期选择的汇率制度应该是对我国经济发展最有利的制度。在现有的国际货币体系下,如果资本项目尚未开放,则理性的选择应该是固定汇率制度;如果资本项目已完全开放,则实行浮动汇率制是有效而保险的。对于中国这样一个资本账户部分开放的国家,现阶段重新回到真正意义上的有管理的浮动汇率制是必要的,也是可行的。     

Relationship equity and switching behavior in the adoption of new telecommunication services

This paper first defines and then presents a model of “relationship equity” for business markets. It points out that the potential benefits of managing relationship equity have been largely ignored and that a general model and stream of relevant research questions could be useful to marketing and relationship practitioners. The model developed considers the special case of key account management as antecedent, two different types of moderator variables, relationship equity as a perception by the buyer, and switching behavior via adoption of new telecommunication services as a result of this perception. The model is used as a basis for developing a number of working propositions.     

国际收支与金融市场效率问题的探讨

以“逆差 顺差”为特点的美国国际收支结构是很难长期持续的,美国经常项目很可能会经历趋向平衡的调整过程。由于中美两国国际收支结构存在较强的互补性,美国国际收支结构的调整对目前中国国际收支结构提出了严峻挑战。金融市场的行政分割、金融资源结构及流向的不合理是影响中国国际收支结构失衡的重要因素,因此中国应该完善和发展金融市场,积极主动地调整目前失衡的国际收支结构以应对美国国际收支结构调整可能给中国经济发展带来的不利影响。

Barriers to the “key supplierization” of the firm

The phenomenon of key supply management (KSM) in business companies is far less investigated than the phenomenon of key account management (KAM) which beneficiates, both in practice and in an academic context, from a growing interest. This article is based on the empirical analysis of a sample of 10 international companies which have recently launched KSM programmes or are currently working on launching such programs. It examines the difficulties these companies come up against when implementing such programmes and proposes to organize these difficulties around three dimensions: 1) the difficulties in implementing real supplier portfolio approaches; 2) the narrow view of value co-creation with suppliers, and 3) the persistent lack of integration of the purchasing function with other internal functions within the company. The conclusion of the article is that KSM is far from being a mere symmetric phenomenon of KAM. Several implications are then discussed in relation to the implementation of KSM programmes within companies.     

External balances,trade flows and financial conditions

This paper studies how changing expectations concerning future trade and financial conditions are reflected in international external positions. In the absence of Ponzi schemes and arbitrage opportunities, the net foreign asset position of any country must, as a matter of theory, equal the expected present discounted value of future trade deficits, discounted at the cumulated world stochastic discount factor (SDF) that prices all freely traded financial assets. I study the forecasting implications of this theoretical link in 12 countries (Australia, Canada, China, France, Germany, India, Italy, Japan, South Korea, Thailand, The United States and The United Kingdom) between 1970 and 2011. I find that variations in the external positions of most countries reflect changing expectations about trade conditions far into the future. I also find the changing forecasts for the future path of the world SDF are reflected in the dynamics of the U.S. external position.     

International spillovers of China's structural reforms

This paper sheds light on the international spillovers of China's reforms in upgrading industrial capabilities, liberalizing capital account, internationalizing the renminbi, and transition to flexible exchange rates. Drawing on two-country New Keynesian model of endogenous entry and portfolio adjustment, we find that China's industrial upgrading that peddles on yuan appreciation lifts all boats through global production network irrespective of capital account convertibility, degree of renminbi internationalization, and exchange rate reform. Feasibility of appreciation-driven upgrading is called into question, however, when renminbi reform and capital account liberalization go in parallel. We also show that international spillovers disappear once renminbi internationalization is associated with liberalized capital account and flexible renminbi exchange rates.

Are Current Account Deficits in the OECD Countries Sustainable? Robust Evidence from Time-Series Estimators

This study examines the sustainability of current account deficits (CADs) and validity of intertemporal budget constraint (IBC) for 24 OECD countries. While the OLSEG, ML system, and OLSGH estimates of the model do not provide support, the GMM, DOLS, and NLLS estimates provide consistent support for the sustainability of CADs across most countries. The estimates of the model with multiple structural breaks reinforce the sustainability of CADs. The results provide dominant support for the sustainability of CADs and validity of IBC across most countries. The CADs are only short-run phenomena and are balanced by future surpluses.
