GPS RMBS起算点偏差对定位影响的研究

GPS RMBS(Relative Moving Baseline System)在工程中有许多重要的应用,例如,远洋编队航行、舰载飞机着舰、编队飞行、空中加油等,但在RMBS中需要伪距单点定位来提供起算点。本文讨论了伪距单点实时定位的精度,由于其精度有限,导出了该起算偏差对定位影响的模型。通过实验,其实算结果表明:由伪距实时单点定位来作为起算点,无论对于基线长还是基线分量都有影响,并且对基线分量的影响大于总基线,但对于10km范围内,其影响仍可以满足cm级高精度的相对定位要求。

后金融危机时代的RMBS和CDO信用评级制度变革路径分析——以信用评级机构政府运营为视角

次贷危机过后,人们总要对发生危机发生的原因进行反思,对信用评级机构监管规则的改进就是最值得反思的问题之一。面对各种各样的观点,我们认为相关的一些制度设计固然有其价值,但在目前的形势下难以奏效。所以,基于对上述路径设计的缺陷的分析,建议设立政府运营的信用评级机构这一模式,因为这一模式具有信息披露及时充分、避免了利益冲突、更有利于投资者利益保护和避免低质量评级的负外部性等优点。虽然该制度设计不是非常完美,但它却是一个相对较好的路径选择。

基于两因素期限结构模型的RMBS定价研究

在住房抵押贷款证券化的过程中,定价是住房抵押贷款支撑证券(residential mortgage-backed securitilization,RMBS)发行与交易的关键,也是其发行成功的前提.针对当前RMBS定价模型数据需求量大、求解复杂等问题,采用HJM利率期限结构方法,通过两因素、无套利利率期限结构模型,构造了零息债券收益率期限结构方程,并给出了参数估计方法;基于期权定价理论,利用随机规划技术,建立了RMBS的定价模型.该模型具有形式简单、易于求解等特点,而且对参数估计所需的历史数据并不严格要求有很长的年限,非常适合抵押贷款开展历史较短的国家.

The use of renminbi for trade and non-trade denomination and settlement

The use of renminbi for invoicing and settlement intermediaries in foreign-oriented activities is the first step and footstone of internationalization of the Chinese currency. With the appreciation of renminbi in recent years, there has been a growth of renminbi invoicing and settlement in China’s border trades, although the overall amount is small and the development momentum is imbalanced among different regions. The main obstacles come from such factors as VAT rebate policy restrictions and foreign exchange control, insufficient financial services, and under-cultivated willingness among enterprises. Looking from the strategic perspective of strengthening macro-adjustment and enhancing the open economy, it is pressing and would be beneficial to China to promote the renminbi’s invoicing and settlement function. Therefore, following the momentum, we should accelerate the construction of a cross-border renminbi clearing system, create non-discriminative treatment in terms of VAT rebate and exchange control policies, and gradually expand the usage of the renminbi from border trades to general trades and outward investment.

RMB:Depreciating Internationally while Appreciating Externally

RMB has been depreciating internally while appreciating externally since 2002. This new monetary phenomenon, has been strengthened in the context that US dollar depreciates internationally and that domestic economy is overwhelmed with excessive liquidities. Certainly the monetary phenomenon is the reflection of the actual economy: continued trade surplus, triggered robustly by the export-driven economy, is bringing a huge amount of exchange reserve which accelerates sequentially the expansion of domestic money supply. Furthermore, a refrained appreciation of RMB tends to deteriorate the domestic inflation, which is not simply a traditional concept of CPI but a broad inflation parameter including a variety of asset prices. It's sure that the new phenomenon is becoming a new challenge to the macroeconomic equilibrium as well as the decision maker of monetary policy.

Is the Chinese Renminbi Undervalued？ An Examination of the B-S Effect Using Diverse Datasets

In 2010, the debate over valuation of the Renminbi is again heating up and the Chinese currency has returned to appreciating against the dollar But is the Renminbi undervalued？ Drawing on the Balassa-Samuelson （B-S） effect on purchasing power parity, we conduct theoretical and empirical analyses of this issue. Theoretical analysis proves that a country＇s real exchange rate will appreciate with rising income, but the currencies of low-income countries tend to be undervalued. In order to avoid biased conclusions resulting from a single dataset or sampling method, we draw on three major publicly-available datasets to examine the B-S effect across 144 economies. Our results indicate that the degree of Renminbi misvaluation is highly dependent on the data source. Synthesizing analyses of diverse datasets, we estimate that the Renminbi was only undervalued by less than 8per cent in 2009. We conclude that China＇s external imbalance most probably results from deep-seated structural imbalances rather than Renminbi undervaluation.

Using fuzzy neural networks for RMB/USD real exchange rate forecasting

In order to aim at improving the forecasting performance of the RMB/USD exchange rate, this paper proposes a new architecture of fuzzy neural networks based on fuzzy logic, and the method of point differential, which guarantees not only the direction of weight correction, but also the needed precision for the BP algorithm. In applying genetic algorithms for optimal performance, this approach, in the forecasting of the RMB/USD real exchange rate from 1994 to 2000, obviously outperforms typical BP Neural Networks and exhibits a higher capacity in regard to nonlinear, time-variablility, and illegibility of the exchange rate.

Nonlinear correlation between RMB internationalization and nonferrous metal prices

The correlation between Renminbi(RMB) internationalization and nonferrous metal prices was studied using the nonlinear Granger causality test and the dynamic conditional correlation-generalized autoregressive conditional heteroskedastic(DCC-GARCH) model. The results indicate that the relationship between RMB internationalization and nonferrous metal prices reflects a complex nonlinear mechanism. There was no mutual influence between RMB internationalization and nonferrous metal prices prior to the trials of the RMB settlement in the cross-border trade in July 2009. Since then, however, a bidirectional causal relationship between RMB internationalization and the price of copper and a unidirectional causal relationship from the price of aluminum to RMB internationalization were examined. In addition, due to the impact of extreme events, such as economic and financial crises, RMB internationalization and nonferrous metal prices are not always positively correlated but are rather occasionally negatively correlated.

What are the Reasons for Keeping Renminbi Stable

Most of the economists agree that renminbi is undervalued, while as for how much it should be appreciated, substantial disagreements exists. At the beginning of this year, analysts abroad tended to think that the renminbi should increase its value by 10% to 15%. The most recent estimates are that the renminbi should appreciate 20% to 30%. This shows the great upward pressure on the renminbi. Since it was devalued in 1994, China’s currency has been kept at a constant nominal level to the US dollar despite china’s rapid economic growth, rising productivity, strong exports, and massive foreign direct investments——all factors that normally cause a currency to appreciated, moreover, the resulting build-up of central bank foreign reserves in itself is sufficient to justify renminbi appreciation. The reasons for keeping Renminbi stable is discussed in this paper.

Belt and Road Boosts RMB Internationalization

Expediting the RMB internationalization in countries along the Belt and Road routes will knock down bottlenecks affecting Chinese investors in exchange rates, financing, and debts, and increase capital resources for these countries.

The Influence of Bond Market Opening in Trade Field on RMB Internationalization Foreign Exchange Rate

In order to verify that the open bond market is the most direct choice to promote the internationalization of RMB,the empirical analysis method is used to analyze the impact of bond liberalization on the internationalization of RMB foreign exchange rate.Firstly,the data source processing method of empirical analysis is introduced.Then the dynamic panel data regression model and panel threshold model are built to verify the influence factors of RMB internationalization foreign exchange rate and the influence of debt market opening on RMB foreign exchange rate,respectively.The results show that the opening of the creditor's rights market has a significant positive promoting effect on the internationalization of RMB foreign exchange rate,and the development of the domestic creditor's rights market has a significant promoting effect on the internationalization of RMB foreign exchange rate.The study has a certain role in promoting the status of China's currency in the international community.

Progress and Prospects of RMB Internationalization in Latin America

Promoting the internationalization of the RMB in Latin America is not only a requirement of the China-Latin American relationship and of China’s reform and opening-up policy in the financial sectors, but is also a strategic choice. With the support of internal, external and bilateral factors,China and Latin American countries have seen a lot progress in RMB trade settlement, investment, financing, and so on, yet Latin American countries’ willingness to use the RMB is still low, there is an obvious shortage of exchange mechanisms, and currency cooperation between them may face more obstacles as China-US competition intensifies. Under these circumstances, in order to further promote the internationalization of the RMB in Latin America, China should seize the opportunity of Latin America’s participation in the Belt and Road Initiative and their demand for currency diversification, as well as the friction between the US-Latin American relationship, start reducing the shortage of institutional exchange mechanisms, and plan for the RMB internationalization process in Latin America at a strategic level.

A geological and functional “three-step strategy” for renminbi's internationalization

Internationalization of the renminbi is the only option for China to fully integrate into the global economic and financial systems. It is not only necessary but imperative as well. With the discussion of advancing renminbi internationalization, benef its and costs must be addressed. We need to closely monitor possible risks and bring out the benefits while averting disadvantages. The overall strategy is to consolidate the groundwork and at the same time actively advance renminbi internationalization and opt for a "three-step" strategy at both strategic and policy levels. To overcome the constraints standing in the way of renminbi internationalization, the basic goals should be: to enhance the readiness of renminbi internationalization, dialectically assess the preconditions, and increase the currency's international circulation as a way to achieve major progress in renminbi internationalization.

Internationalization of the Renminbi:Status and Prospects

The recent global financial crisis has revealed great defects in the US dollar dominated international monetary system.In response,countries and international organizations have developed numerous proposals for reform of the system.With China's growing economic presence,the renminbi is gaining recognition and acceptance in international markets and is slowly beginning to play a significant role in trade settlement and offshore market development.Meanwhile,it is important to remain aware of the limitations of renminbi internationalization and the gaps that exist between it and other major world currencies.Once fully implemented,renminbi internationalization will result in it becoming a major currency on the world stage in approximately 15 years.

Volatility of the Exchange Rate after Renminbi Inclusion into the SDR：Test of Stability and Representation

The special drawing rights(SDR) must have stability and representation in order to serve as reserve assets and the unit of account for bulk commodities and assume the function as a potential international currency. By introducing such factors as China's share in global trade volume in 2013, this paper found that the covariance between the SDR and the price fluctuations of major commodities is the smallest after Renminbi inclusion into the SDR. The covariance is more or less halved compared with the SDR without Renminbi. Then, based on our comparison of volatility in the effective exchange rates(EER) of various countries(extensively used) and the volatility in the SDR exchange rate(seldom used), we found that despite similar trend curves, the SDR's volatility can explain for a very small part of the volatility in effective exchange rate. The residual error indicates that the share of SDR is limited in the volatility of effective exchange rates of various countries on the one hand and suggests that it is urgent to expand the SDR to include representative currencies, particularly the currencies that represent significant weights of world trade. Relevant tests demonstrate that Renminbi inclusion into the SDR will not only enlarge the stability of SDR but enlarge its function as an index currency through the extension of SDR's function as the unit of account for major world commodities and the inclusion of the currencies of other major trading nations, so that the representation as the global unit of account will be enlarged. In addition, the inclusion into the SDR also helps Renminbi become a component of the international reserve currencies and supplement its liquidity supply.

New Ideas for RMB Internationalization under the Belt and Road Initiative

President Xi Jinping put forward that, "China will further push the open economy to a higher level by enlarging its scale, expanding its area, and deepening its degree." This proposal provides new perspectives for RMB internationalization. The new path of RMB internationalization shall be achieved under the Belt and Road Initiative and be a new option that is di erent from the "Three-Stage Theory" and regional monetary cooperation. RMB internationalization can only be realized through a government-driven mode with Chinese characteristics which shows the fundamental di erence from the internationalization of other currencies such as the US Dollar, Euro and Japanese Yen. The Chinese government can realize the strategic objective of RMB internationalization through improving national governance, applying policies and tools for macroeconomic regulation, and implementing the Belt and Road Initiative, as well as the operation of its nancial industry, the Silk Road Fund(SRF), and that of regional banks like the Asian Infrastructure Investment Bank(AIIB) and the BRICS New Development Bank(NDB). RMB internationalization is an important objective of China's political and economic development. Efforts must be made to steadily promote market-oriented reform of the RMB exchange rate and its forming mechanism, and reform of capital account convertibility so that RMB can become the leading global reserve currency. Meanwhile, China will also undertake more responsibilities as a major power for stable development of the international economy and nance.
