析我国外汇占款对冲策略

根据我国的经济运行情况,分析固定汇率、资本流动与货币政策自主的“三元困境”在我国的具体表现。指出在经常项目和资本项目持续顺差的情况下,货币政策与外汇储备增长的矛盾。说明为控制流通中的货币而被动进行的单向对冲操作的成本昂贵,并且是以牺牲货币政策自主为代价的,还易积蕴金融风险,酿致恶性后果。证实了外汇占款对冲策略的不可持久性,为此必须改革现行的固定汇率制度,并放松资本管制。     

浅议我国银行监管制度的完善

银监会成立后,我国的银行监管工作进入了一个新的时期。但是由于历史的原因以及中国银行业本身的局限性,我国在银行监管方面仍面临许多问题。首先对我国银行监管制度的现状与暴露出来的问题进行较为深入地分析,进而就如何改进和加强银行监管工作,完善银行监管制度,提出了对策与建议     

资本永续盘存法及其国内应用

资本存量数据是宏观经济运行政策研究的重要决定因素。资本存量核算比较复杂，在理论与技术两个层面都存在诸多问题难以厘清。我国资本统计十分薄弱，数据可得性成为资本存量估算的严重制约。在我国经济增长研究中，如何准确估算资本存量一直是困扰研究者的难题。学术界需要使用这方面数据，又促使很多学者基于各自的研究目的对我国资本存量进行估算。这些研究分别利用不同的假设和处理方法，这使我国资本存量数据出现了差异很大的众多版本。本文在对资本存量估算方法进行梳理之后，对我国资本估算现有研究进行了回顾和评论。     

Capital control and exchange rate volatility

The study offers one conceptual and theoretical framework for evaluating the economic effects of a trading tax on foreign exchange transactions. Taxes and the price stickiness mechanism are taken into account in the model. When prices are flexible, full monetary neutrality can be obtained even in the short-term. Intuitively, taxes on foreign exchange transactions discourage speculation by rising currency trading costs, and, thus, increase the stability of the exchange rate. Finally, the results show that not only the exchange rate but consumption, investment and employment will become less volatile by imposing trading taxes on foreign exchange transactions.     

美国银行业资本监管演变与新进展

文章旨在梳理美国银行业资本监管体系的演进过程,通过时序研究方法揭示美国银行业资本监管的发展动态与脉络。研究发现,美国银行业资本监管与其经济发展趋势密切相关,经济繁荣期监管当局倾向放松监管,这其中有着十分复杂的利益攸关方的激烈博弈,而在经济衰退期,在金融体系风险的压力下,监管当局会收紧监管标准。从中可以窥见,上世纪20年代前的宽松监管与1929年大萧条,二次世界大战后的经济繁荣与70年代经济滞涨,监管加强,80年代初的放松管制与80年代中后期银行大量倒闭,90年代金融服务现代化法案与2008年的全球金融危机,交替出现的银行业监管放松与收紧的变化有着内在的规律性。研究美国银行业资本监管历史、监管体系和监管措施,有助于我国加强银行体系的风险防范,完善银行业资本监管制度和机制。     

我国茶产业全要素生产率增长及其分解--基于随机前沿生产函数的分析

文章利用超越对数的随机前沿生产函数,测算了1996-2007年我国茶产业的全要素生产率。研究表明：研究期间我国茶产业TFP平均增长0.70%,平均技术进步率为1.42%,平均技术效率为72.05%,但都呈逐步下降趋势; TFP增长的主要来自技术进步,但技术效率的变化和规模报酬率出现一定的退步,阻碍TFP的增长;各省份TFP增长有差异,其中四川省的TFP增长速度最快,而湖南省和陕西省的TFP成负增长;我国茶叶的劳动产出弹性逐年增大,而资本产出弹性逐渐变小,且我国茶叶生产一直处于规模报酬递减状态。     

External constraints and endogenous growth: Why didn't some countries benefit from capital flows?

Empirical evidence on the growth benefits of capital inflows is mixed. The growth benefits accruing from capital inflows also appear to be larger for high savings countries. We explain this phenomenon using an OLG model of endogenous growth in open economies with borrowing constraints that can generate both positive and negative growth effects of capital inflows. The amount an economy can borrow is restricted by an endogenous enforcement constraint. In our setting, with physical capital and a pay-as-you-go pensions system, the steady state is unique. However, it can either be constrained or unconstrained. In a constrained economy, opening up to equity and FDI inflows can be bad for growth because it makes the domestic interest rate too low, which endogenously tightens borrowing constraints. Agents decrease savings and investment in productivity-enhancing activities resulting in lower growth. Results are reversed in an unconstrained economy. We also provide a quantitative analysis of these constraints and some policy implications.     

Risk‐Off Episodes and Swiss Franc Appreciation: The Role of Capital Flows

During episodes of increased global risk aversion, or risk‐off episodes, safe haven currencies such as the Swiss franc tend to appreciate. The immediate impact of a risk‐off shock is an increase in net private inflows to Switzerland, mostly driven by a reduction in Swiss residents’ net purchases of foreign debt securities and reduced foreign exposure by Swiss banks. Given that the bulk of capital movements related to risk‐off episodes is driven by decisions of Swiss residents, capital flow management policies that discriminate based on the residency of the investor (capital controls) are not likely to be effective at reducing the impact of risk‐off episodes. However, prudential policies that limit leveraging or foreign exposure by Swiss banks may diminish the volatility of capital flows during risk‐off episodes.     

Assessing the Impacts of Capital Inflows on Domestic Economy across the Sub-Saharan Africa Countries

Using GMM models, this paper analyzes the impacts of capital inflows on domestic investment in 44 Sub-Saharan Africa (SSA) countries from 2003–2012. It is found that foreign direct investment across the SSA remains to be the largest percentage share, accounting for 35% of the total capital inflows. FDI inflows have significant positive impacts on domestic investment across the SSA in both short term and long term. Other key macroeconomic factors such as age dependency ratio, domestic economic growth, terms of trade, real effective exchange rate and trade openness also play vital roles in determining domestic investment.     

The Economics of State Subsidies in Early Stage Financing

We analyze the effect of state subsidies on early stage investments. In a two‐period investment model with incomplete stage financing contracts, we describe optimal and second‐best investment levels. Optimality depends on external effects: given that private early stage financing generates positive external effects, the subsidies might be designed to use scarce state money most efficiently to mobilize private investment capital. However, a subsidy might also contribute to greater efficiency of the contractual relationship itself without regard to external effects. Refinancing subsidies can be optimal under both perspectives and are always optimal under last of the two approaches. The comparison of the main types of subsidies, i.e. refinancing subsidies, guarantees and direct investments, speaks against the use of guarantees. Finally, we show that our results do also hold if some investors (e.g. venture capitalists) have a superior screening capability.
