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.     

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.     

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.

Environmental factors influencing the management of key accounts in an Arab Middle Eastern context

Within the sales and marketing literature, it is recognised that a range of external factors can influence how companies in the business-to-business field manage business relationships within national and across international borders. However, there have been very few studies that explore the influence of the external environment on key account relationships, especially within the context of emerging economies. This study draws on the network approach and contingency theory to identify and highlight the influence of external environmental factors on the management of inter-organisational relationships with key customers in emerging economies in the Arab Middle East region. It is based on an extensive qualitative enquiry that utilises 50 in-depth semi-structured interviews conducted in Jordan with endogenous and Western firms. It concludes that key account practices within an Arab context are shaped by a number of contingencies that are embedded in broader institutional contexts and the business environment, which may challenge the adoption of company-wide universal key account management policies across borders.     

News-driven international credit cycles

How does news about future economic fundamentals affect within-country and cross-country credit allocation? How effective is unconventional policy when financial crises are driven by unfulfilled favorable news? I study these questions by employing a two-sector, two-country macroeconomic model with a banking sector in which financial crises are associated with occasionally binding leverage constraints. In response to positive news on the valuation of non-traded sector capital which turns out to be incorrect at a later date, the model captures the patterns of financial flows and current account dynamics in Spain between 2000–2010, including the changes in the sectoral allocation of bank credit and movements in cross-country borrowing during the boom and the bust. When there are unconventional policies by a common authority in response to unfulfilled favorable news, liquidity injections perform better in ameliorating the downturn than direct assets purchases from the non-traded sector.
