人民币汇率管理技术研究

新的人民币汇率形成机制对汇率管理提出了更高的技术要求。人民于汇率管理技术作为一种重要的生产力,为人民币汇率管理提供了重要的操作技巧和技术支持。创新和发展人民币汇率管理技术,有利于进一步提高人民币汇率管理效率和外汇资源配置效率。人民币汇率管理技术的变近大致经历了萌芽阶段、起步阶段、徘徊阶段和快速发展4个时期;人民币汇率管理技术的创新内容包括人民币汇率机制管理技术、弹性管理技术、风险管理技术和信息管理技术等;人民币汇率管理技术的未来发展方向应由“原始型、初级型、封闭型、粗放型、僵化型”向“现代型、市场型、开放型、集约型、创新型”转变。同时,针对人民币汇率管理技术发展中的制约因素,还要注意发展策略的选择,如培育有效的外汇专场主体．加强汇率基础设施建设,营造汇率生态环境,培养金融技术人才等。

ExpertLens: A system for eliciting opinions from a large pool of non-collocated experts with diverse knowledge

The complexity of policy decision-making raises the need to elicit opinions from large and heterogeneous groups of stakeholders with broad and diverse sets of expertise. Existing options for elicitation include small face-to-face panels of experts by using the Nominal Group Technique (NGT), large Delphi panels whose members do not interact with each other face-to-face, and crowdsourcing, which involves an open call for input issued to a large community of people. In an attempt to close the gap between the practical needs of policy makers and the methodological challenges associated with eliciting opinions of large, diverse, and distributed groups, we have developed a new online elicitation system and methodology called ExpertLens. By optimizing the direct interactions of NGT with the larger number of Delphi participants and the wisdom of “selected crowds,” our approach is designed to save on the costs associated with traditional expert panels, while increasing accuracy in elicitation by reducing the potential for group process losses that can occur in large, diverse, and non-collocated panels whose members interact via asynchronous online discussion boards. The ExpertLens approach is iterative, does not require participants to develop consensus, and determines what the group “thinks” by statistically analyzing data collected in all rounds of the elicitation. This paper describes the ExpertLens system and methodology, briefly discusses recent ExpertLens trials, provides conceptual arguments for why it is an appropriate model for eliciting expert opinions, illustrates its main components and analytics by using an infrastructure investment example, and discusses a research agenda for testing the underlying tenets of the ExpertLens approach.

Risk-sharing and Growth: The Role of Precautionary Savings in the "Education" Model

While the "risk amelioration" literature suggests that risk-sharing channels savings into risky but productive technologies and hence favours growth, models focused on precautionary savings reverse this conclusion. We solve, by means of numerical techniques, a model based on human capital accumulation through education, and find that the increase in precautionary savings makes labour more productive in the goods sector and draws resources from education, which is the "growth leading" activity. Hence, we establish a result favourable to financial integration, even in a model where precautionary savings play an important role.     

Foreign Direct Investment and the External Wealth of Nations: How Important Is Valuation?

While the balance sheet approach has increased the focus on position data, differences in valuation practices for foreign direct investment (FDI) make cross‐country comparisons difficult. To enhance comparability, the IMF's Balance of Payments and International Investment Position Manual, sixth edition, which some countries have already implemented and others will implement in the coming years, recommends seven methods for valuation of unlisted FDI. This paper demonstrates that both the valuation method and simple differences in estimation techniques can fundamentally change a country's financial balance sheet. Using Denmark as an illustration, unlisted FDI equity liabilities vary from 22 to 156 percent of GDP when applying different estimation techniques, but just one valuation method, price to earnings. These measurement uncertainties can lead to important misunderstandings and affect policy recommendations, thus pointing to the need for further international harmonization. While the results are presented in an FDI context, the uncertainties also apply to other macroeconomic datasets, including national accounts statistics.
