中国的金融市场开发要打造新的模式

当今全球的金融市场上,市场对金融系统的压力越来越大,传统的融资方式已经不能满足投资者的需要。一种新的金融工具—贷款证券化,使资金拥有者可以通过这一渠道将资金转移到贷款者手中。这种形式可以很好地解决当今社会许多融资难的问题,如果能够在我国的金融体系中得到完善,会极大地促进我国的经济建设,也能很好地解决我国金融体系的现实问题。     

Fast delta computations in the swap-rate market model

We develop an efficient algorithm to implement the adjoint method that computes sensitivities of an interest rate derivative to different underlying rates in the co-terminal swap-rate market model. The order of computation per step of the new method is shown to be proportional to the number of rates times the number of factors, which is the same as the order in the LIBOR market model.

A Comparison of EPI Sampling, Probability Sampling, and Compact Segment Sampling Methods for Micro and Small Enterprises

Finding an efficient method for sampling micro- and small-enterprises (MSEs) for research and statistical reporting purposes is a challenge in developing countries, where registries of MSEs are often nonexistent or outdated. This lack of a sampling frame creates an obstacle in finding a representative sample of MSEs. This study uses computer simulations to draw samples from a census of businesses and non-businesses in the Tshwane Municipality of South Africa, using three different sampling methods: the traditional probability sampling method, the compact segment sampling method, and the World Health Organization's Expanded Programme on Immunization (EPI) sampling method. Three mechanisms by which the methods could differ are tested, the proximity selection of respondents, the at-home selection of respondents, and the use of inaccurate probability weights. The results highlight the importance of revisits and accurate probability weights, but the lesser effect of proximity selection on the samples' statistical properties.

Measuring Net Foreign Assets： The Case of China

This paper discusses two methods of measuring net foreign assets（NFA）： directly using the financial account and indirectly using the current account. The former method is found to be more accurate than the latter method. The paper also includes a detailed discussion of the valuation methodology. The results show that China＇s NFA are much lower than the cumulative current account surplus or the cumulative foreign exchange reserves. This leads to an underestimation of growth in foreign direct investment and an overestimation of the capacity of foreign exchange reserves to cope with possible withdrawals. Therefore, the Chinese Government should pay more attention to valuation issues to obtain more accurate measurement of NFA. Meanwhile, the Chinese monetary authority should relax its control on the foreign exchange settlement system, allow the private sector to hold a certain amount of foreign exchange, and encourage foreign assets to be denominated in RMB to solve structural problems, including entity and currency mismatch
