基于交换费机制的多方博弈下的银行卡定价模型

为寻求维护和培育我国银行卡体系良性运作的策略,本文运用博弈分析法和定价模型研究了银行卡收费和定价问题,结果表明,银行卡组织应征收交换费来平衡银行卡双边市场两端,而银行卡组织在"社会福利最大化"和"交易量最大化"两种不同理念驱动下,应分别采取对"效用较高的一端减少交换费的收取额"和"收益较高的一端收取较多的交换费"的定价策略。

论欧元汇率波动：一个欧美博弈视角

欧元自1999年面世以来,其走势和前景引起众人关注,许多人纷纷利用购买力平价等各种汇率决定理论对其汇率走势进行预测,然而其汇率变化仍然出乎意料,欧元从最初的一路狂跌,到2002年以来强劲上扬。传统经济学理论无法预测和解释欧元的波动,而欧美博弈,尤其是美国政府的态度,对于欧元的波动影响颇大。欧元虽然潜力巨大,但是冲击美元的霸主地位尚需时日。     

中美利率与汇率联动关系的实证研究:2005～2008

在经济金融全球化的今天,尤其伴随我国金融业全面开放、人民币国际化进程的逐步推进,中美利率与汇率联动关系的研究显得日益重要。本文在借鉴经济学有关利率和汇率联动关系的理论模型和传导机制的基础上,运用计量经济学理论模型和统计软件Eviews5.0,通过对利率与汇率经济变量的平稳性检验、协整关系检验、因果关系检验、冲击反应分析和方差分解检验,较为全面地对中美利率与汇率的联动关系进行了实证分析。通过实证分析,我们发现中美利率和汇率在长期内存在协整关系,但短期联动关系不足,我国应加快推进利率市场化进程,积极完善人民币汇率形成机制,使我国利率政策和汇率政策相互协调,促进宏观经济向内外均衡发展。     

Recursive Moments of Compound Renewal Sums with Discounted Claims

Under regularity conditions, Le´veille´& Garrido [6] gives a derivation of the first two moments (resp. asymptotic) of a Compound Renewal Present Value Risk (CRPVR) process using renewal theory arguments. In this paper, with the same procedure and assuming that all the moments of the claim severity and the claims number process exist, we get recursive formulas for all the moments (resp. asymptotic) of the CRPVR process.     

人民币汇率变动趋势及其对区域货币合作的影响

人民币汇率变化及其汇率政策的选择,对于东亚区域货币金融合作和人民币的国际化有着重要意义。本文通过考察近年来人民币与世界主要货币及东亚其他货币的联动关系,分阶段探讨了人民币汇率变动对东亚货币的影响,指出人民币有条件地成为本地区潜在的"锚"货币,但现阶段这一功能只能通过保持与美元汇率的相对稳定得以实现,人民币要想独立成为东亚区域性关键货币,取决于中国能否在某种程度上替代美国成为区域内最终产品的市场提供者。同时,现阶段东亚地区制度化的汇率合作应当缓行,但有必要进行某种程度的汇率政策协调,人民币汇率政策的选择应当考虑区域合作因素。

Government Time Discounting and Required Rates of Return: UK History and Current Issues

The UK government first set financial objectives for the nationalised industries in 1961 and subsequently promoted the use of ‘discounted cash flow’ for investment appraisal. The nationalised industry regime evolved until, in the 1990s, it was succeeded by economic regulation regimes for the privatised utilities. Meanwhile discounting conventions emerged and have continued to evolve for wider government policy analysis, including aspects of climate change. Issues about the size and functions of public expenditure notwithstanding, UK government conventions are currently fairly uncontroversial: however, in the world at large, government discounting remains subject to many academic and international controversies and misunderstandings.     

The real dollar-yen exchange rate,asymmetries in trade flows and the current account in a perfect-foresight model for developing East Asia

This paper explores permanent, unanticipated shocks in the yen-dollar exchange rate in a perfect-foresight, infinite-horizon, representative-agent model for an open, semismall economy that produces a single good, imports intermediate inputs and investment goods from Japan and competes with Japan in external markets. Therefore, the model captures some of the features of the developing countries of East Asia. External debt is constrained by a country-risk premium that depends on the level of external debt. The capital stock is maintained and incremented by an endogenous mixture of Japanese and home goods. An appreciation of the dollar against the yen is neutral for external indebtedness and the trade account in the long run, but raises the capital stock, consumption and hence welfare in the long run; the home currency depreciates against the dollar but appreciates against the yen. Whether a cycle of current account surpluses followed by current account deficits or vice versa is generated depends on the initial response of the shadow value of external debt.
