Relative Guarantees

Many real-world financial contracts have some sort of minimum rate of return guarantee included. One class of these guarantees is so-called relative guarantees, i.e., guarantees where the minimum guaranteed rate of return is given as a function of the stochastic return on a reference portfolio. These guarantees are the topic of this paper. We analyse a wide range of different functional specifications for the minimum guaranteed rate of return, hereunder both so-called maturity and multi-period guarantees. Several closed form solutions are presented.     

Competition and Information Production in Market Maker Models

Abstract:   The microstructure literature models the mechanisms through which fundamental information is incorporated into market prices. This paper extends previous models by endogenising information production and analysing incentives for costly information production. In contrast to the existing literature, increasing the number of informed traders can result in reduced price informativeness. When prices have an allocative role this has welfare consequences: the regulatory implications of a dichotomy between private and public incentives for information gathering are discussed.     

试论新制度经济学与中国体制改革的契合

中国正在经历一个制度变迁的时代。新制度经济学对中国体制改革实践有很强的解释力和指导性，它与马克思主义经济学在机理上的相通及其与中国的传统政治文化的契合促进了它在中国的进一步发展。中国正处于一个制度变迁的时代，新旧体制转轨使中国有了对新的经济制度变革理论的强烈需要。新制度经济学适应了这种需求，对中国体制改革实践有很强的解释力和指导性。新制度经济学与马克思主义政治经济学有相通之处，这有利于发展新制度经济学，也有利于中国经济理论的衔接和发展。中国的传统政治文化与新制度经济学理论的契合，既有利于新制度经济学的传播，也有利于中国体制改革的进一步发展。

On the test of the correction mechanism for mis-pricing between assets using a statistical yield spread model

This paper investigates the existence of a correction mechanism for mis-pricing between Japanese stock and bond. By this correction mechanism we mean that when deviations occur from the equilibrium levels of the expected return differentials between stock and bond — the risk premium differentials, the market will tend to correct the mis-pricing and bring the expected return differentials back to the equilibrium levels. We assume that the yield spread between the predicted earnings price ratio of stock and the yield to maturity of bond reflects the risk premium between stock and bond, and estimate the equilibrium risk premium differentials and mis-prices between stock and bond by modelling their behaviors with a statistical yield spread model (SYS). Empirical results strongly indicate the existence of the mis-pricing correction mechanism, suggesting the inefficiency of securities markets.     

The impacts of Hong Kong’s Currency Board reforms on the interbank market

Among the economies with a Currency Board System (CBS), Hong Kong (HK) is probably the one with the largest and most developed financial sector, as well as the highest capital mobility. Hence, studying HK’s CBS is not only crucial to HK, but also important for the understanding of the modern CBS. This paper outlines the major monetary reforms in HK since the late 1980s. The impacts of these reforms and the 1997–1998 Asian Financial Crisis are then examined empirically. We focus on the differentials between the US and HK interbank interest rates. We assume the conditional-mean equation follows an autoregressive process and the conditional-variance equation follows a generalized autoregressive conditional heteroscedasticity process. This model captures the time-varying level and volatility of the differential. In light of the empirical results we provide an assessment of the reforms in HK.     

近10年日本宏观经济的理论分析与展望

近10年日本经济停滞不前，一方面对外经济状况不佳：日元对美元汇率技术下跌。且不断加剧；出口增长放缓，贸易顺差连续下滑，另一方面国内宏观经济状况严峻；失业率不断上升，内需不振；通货紧缩逐步加深；工业增长持续低迷，工业生产与效益下降，究其原因，用内外均衡模型理论分析得出，日本经济没有达到均衡的0点，内外均衡遭到了破坏，而展望今后的日本经济和日元走势，基于日本财政状况的恶化及货币政策的失效，估计还不会导致资本的大量外流。也不会对资本流动产生重要的影响，而结构改革也将可能引致日元升值。

Differential reporting in Germany - A historical analysis

Based on a contingent perspective of accounting change, this paper reviews the historical development of differential reporting in Germany, by drawing on primary and secondary sources. The main objective of the paper is to shed light on the driving forces and main influential parameters that have shaped the existing differential reporting framework. This historical approach supplies interesting insights for the current discussion on differential reporting in Germany produced by the EU Regulation on the application of International Accounting Standards.
