异质预期条件下中央银行沟通对人民币汇率波动的影响

在外汇市场交易者预期异质性的假设条件下,以2005年7月至2015年12月中国人民银行沟通频数和人民币汇率数据为样本,采用异质预期汇率模型考察中央银行沟通对人民币汇率波动的总体影响。研究发现：在异质预期条件下,中央银行沟通通过信息机制和协调机制影响外汇市场交易者的异质预期,从而对人民币汇率波动产生较为显著的影响,但由于我国外汇交易者预期向基本面预期转换的发生概率小于技术分析交易者预期,中央银行沟通对人民币汇率波动的平稳作用效力受到一定的局限。     

央行政策沟通的金融资产价格稳定效应——以中国股票市场为例

本文研究中国央行不同形式、不同主体、不同意图、不同时间政策沟通的稳定金融资产价格效应以及央行"言行一致"对政策效果的影响.实证结果显示:(1)央行沟通能够显著影响股票价格且能够降低资产价格波动.(2)从形式看,书面沟通较口头沟通对市场影响更大;从主体上看,行长沟通效果好于他人沟通;从政策意图上看,紧缩意图的政策效应大于宽松政策.(3)随预期管理重要性的提升,沟通效果得以更好发挥.(4)央行"言行一致"能够更好地稳定资产价格,"言行相悖"则会造成预期混乱,降低政策效果.     

央行汇率沟通与股票市场波动

本文基于2005年7月至2017年2月的日度数据,检验中国央行汇率沟通对于股票市场波动率的影响,研究结果发现:(1)央行汇率沟通会对本国股票市场产生明显的溢出效应,并显著增加股票市场的波动率,B股市场波动率反应程度显著强于A股市场。(2)书面沟通的效果强于口头沟通,口头沟通中行长沟通效果强于非行长沟通;汇率贬值的沟通效果显著强于汇率升值沟通。(3)汇率沟通对于股票市场波动率的影响存在着明显的非线性。     

人民币汇率波动与我国通胀、产出波动：一个扩展泰勒曲线的研究

发挥市场供求对汇率的调节作用,增强人民币汇率双向浮动弹性,是当前我国汇率体制改革的主要方向。本文在泰勒曲线的框架下考察人民币汇率波动对我国宏观经济波动和货币政策实施的影响。通过实证研究发现,1994—2006年通货膨胀波动对人民币汇率波动是不敏感的,人民币汇率传递效应不显著,人民币汇率波动对宏观经济波动没有显著的影响;2007年以后人民币汇率波动推动泰勒曲线向内移动,因此更大的人民币汇率弹性对货币政策传导和货币政策有效性是有利的,逐步扩大的人民币汇率弹性区间对我国宏观经济运行是适宜和可接受的。另外人民币汇率波动也使得泰勒曲线更加陡峭,稳定通货膨胀所导致的产出缺口波动减小了,因而更有利于货币政策当局追求一个低而稳定的通胀目标。     

美国量化宽松货币政策退出对我国金融资产价格的影响

随着美国经济的复苏,美联储逐渐退出了其自2008年来采取的量化宽松货币政策,美国经济进入加息周期.在美联储加息预期下,全球金融资产价格波动频繁.美国量化宽松货币政策退出对我国金融资产价格影响如何?本文以2013年11月至2016年6月美联储的持债规模和上证指数、美元兑人民币汇率中间价、一年期Shibor数据为样本,采用VAR模型实证分析了美国量化宽松货币政策退出对我国金融资产价格的影响.结果显示,美国量化宽松货币政策退出对美元兑人民币汇率中间价有显著的正向冲击,人民币具有贬值的压力;对上证综合指数有负向冲击,我国上证综合指数在美国量化宽松货币政策退出期间会降低;对一年期的Shibor有正向冲击,一年期的Shibor在美国量化宽松货币政策退出期间会上浮.     

人民币汇率波动对我国货币流动性的影响研究

本文分阶段对2005年汇改前后人民币汇率及人民币汇率波动对货币流动性及银行流动性的影响进行了研究。实证研究表明：从长期看来,人民币汇率水平与流动性正相关,即人民币升值会增加流动性,但人民币汇率波动会使这一效果减弱;汇改后人民币汇率波动对流动性的作用变得更加明显;相比较作用于银行的流动性效果来看,人民币汇率宏观上对货币的流动性影响更加明显。     

中央银行沟通的金融市场响应──基于股票市场的事件研究

本文使用事件研究法分析我国中央银行沟通行为对股票价格走势的影响。研究发现,影响确实存在且影响方向和力度与央行沟通方式以及股票市场背景有关。具体而言:(1)书面沟通影响显著,口头沟通则无明显作用;(2)宽松性政策信息沟通产生了正向影响,紧缩性信息沟通影响为负;(3)沟通事件的影响主要体现为一种短期作用,并伴随着即时效应、预知效应和滞后效应;(4)在熊市或牛市的不同市场背景下,央行沟通对股价的影响存在非对称性。结果表明,央行的沟通手段对金融市场有重要影响。     

人民币与金砖国家汇率市场间波动溢出效应研究

随着金砖国家货币与金融合作的不断深化,汇率波动对金砖国家货币政策及金融改革的影响也日益增强。本文选取自2011年以来金砖国家汇率高频数据为研究对象,基于BEKK-MGARCH(1,1)模型对人民币与金砖国家汇率的波动溢出效应进行分析。实证结果显示:金砖国家汇率波动均不服从正态分布且具有明显的集聚效应;人民币与金砖国家各汇率市场间的波动溢出效应存在明显差异。     

人民币汇率波动对我国货币供给影响的机制探析

人民币汇率制度改革后,人民币汇率波动对我国货币供给的影响越来越强。本文从货币供给决定模型和我国中央银行资产负债表的分析发现,人民币汇率波动会影响我国的货币供给。进一步分析发现,人民币汇率波动通过我国国际收支的经常项目路径、资本和金融项目路径、储备资产路径和我国货币政策的公开市场操作路径、信贷传导路径影响我国的货币供给。最后,在本文分析的基础上提出了相关政策建议。     

货币政策冲击与人民币汇率动态

传统的货币政策冲击是通过短期约束或者长期约束下的向量自回归模型识别的,由于这种识别方法往往会引起"价格之谜"悖论,为保证实证分析的稳健性,本文同时采用短期约束和符号约束(Uhlig,2005)方法识别货币政策冲击,并对中国2005～2011年的数据进行实证检验,给出货币政策冲击对汇率影响的证据。结果表明,中国采取紧缩货币政策减少货币供应量,以及美国采取宽松货币政策降低短期利率,均会引起人民币兑美元汇率持久性升值,前者对汇率变动的解释能力更强,但解释比例不超过50%,并且实证分析认为人民币兑美元汇率没有产生超调现象。由于货币政策等外部冲击以及市场的不完全性,会导致汇率异常波动,我们认为央行适度的外汇干预仍然是有必要的。     

Bayesian Premium Rating with Latent Structure

We propose a fully Bayesian approach to non-life risk premium rating, based on hierarchical models with latent variables for both claim frequency and claim size. Inference is based on the joint posterior distribution and is performed by Markov Chain Monte Carlo. Rather than plug-in point estimates of all unknown parameters, we take into account all sources of uncertainty simultaneously when the model is used to predict claims and estimate risk premiums. Several models are fitted to both a simulated dataset and a small portfolio regarding theft from cars. We show that interaction among latent variables can improve predictions significantly. We also investigate when interaction is not necessary. We compare our results with those obtained under a standard generalized linear model and show through numerical simulation that geographically located and spatially interacting latent variables can successfully compensate for missing covariates. However, when applied to the real portfolio data, the proposed models are not better than standard models due to the lack of spatial structure in the data.     

The development of the group accounts disclosure system in Japan

The Japanese disclosure system of consolidated statements was introduced in 1977 and extensively revised in 1997. The role of the bureaucracy has been significant in these developments and seems to be part of Japan's closed culture. However, other explanations could also be applied. In particular, although Japanese firms opposed such disclosures on the basis of preparation costs, the Japanese government had to modernize the disclosure system, including consolidation, in order to develop the securities market regardless of an individual company's interests.     

Moments of Compound Mixed Poisson Distributions

Recursive formulae are derived for the evaluation of the moments and the descending factorial moments about a point n of mixed Poisson and compound mixed Poisson distributions, in the case where the derivative of the logarithm of the mixing density can be written as a ratio of polynomials. As byproduct, we also obtain recursive formulae for the evaluation of the moments about the origin, central moments, descending and ascending factorial moments of these distributions. Examples are also presented for a number of mixing densities.     

The designing of corporate accounting law in Japan after the Second World War

After the Second World War, during the neutralization of the controlled economy of wartime Japan, a design for a Corporate Accounting Law was elaborated by the Investigation Committee on the Business Accounting System. The Investigation Committee tried to establish not only new business accounting standards but also a central and independent administrative organ of corporate accounting regulation on the basis of the Corporate Accounting Law. The Corporate Accounting Law was expected to lay the legal foundation of the new corporate accounting regulation regime in Japan. Nevertheless, even though the original design of the fundamental accounting law was never realized, it should be considered the starting point for our understanding of external accounting history in post-war Japan.     

The deliberation around accounting techniques: accounting for depreciation and foreign exchange in an Indian jute company, 1870-1900

This paper examines the way two accounting techniques, namely depreciation and foreign exchange, were deliberated on, between 1870 and 1900, in an Indian jute company whose shareholders resided in the UK. The arena for these deliberations was the conflictual relationship between controlling and non-controlling shareholders as to how best to account for depreciation and foreign exchange especially when the particular accountings affected distributional issues such as the dividend decision. The purpose of this paper is to analyse and explain the processes by which a company's accounting practices emerge and develop as a contest between different interests. Accounting framed the parameters of the deliberations and provided the language of power and dissent. The paper uses a rich archive that includes narrative and accounting material.     

Short-sale refinancing and price adjustment speed to bad news: Evidence from a quasi-natural experiment in China

Short selling may accelerate stock price adjustment to negative news. However, the literature provides mixed evidence for this prediction. Using short-sale refinancing and a staggered difference-in-differences (DID) model, this paper explores the effect of short selling on stock price adjustment. Our results show that (1) short-sale refinancing improves the speed of stock price adjustment to negative news. This result holds after we control for endogeneity. (2) The positive relationship between short-sale refinancing and stock price adjustment speed is significant in subsamples of stocks with higher earnings management or lower accuracy of analyst forecasts, indicating that firms with more opaque information are more likely to be targeted by short sellers. In subsamples of stocks with a higher ownership concentration or lower ownership by institutional investors, short selling is more likely to increase the speed of stock price adjustment, indicating that ownership structure may influence negative news mining. (3) As short-sale refinancing exacerbates the absorption of bad news by stock prices, it increases crash risk. This study enriches the research on the economic consequences of short selling and provides empirical evidence supporting regulations on short selling in China.     

Pricing Dynamic Insurance Risks Using the Principle of Equivalent Utility

We introduce an expected utility approach to price insurance risks in a dynamic financial market setting. The valuation method is based on comparing the maximal expected utility functions with and without incorporating the insurance product, as in the classical principle of equivalent utility. The pricing mechanism relies heavily on risk preferences and yields two reservation prices - one each for the underwriter and buyer of the contract. The framework is rather general and applies to a number of applications that we extensively analyze.
