最优货币政策规则参数的估计和中国货币状况指数的测度

本文从宏观经济的一般均衡模型出发,融入了股票价格和房地产价格变动,考察我国中央银行货币政策调控在经济增长和通货膨胀之间的目标规则,分析了影响货币政策规则参数变化的主要因素及潜在机制。本文的实证结果显示中央银行最优货币政策参数为0.144055,央行货币政策是逆周期操作,也意味着中央银行在制定货币政策时,赋予通货膨胀目标更高的权重;同时我国货币政策是逆房地产市场周期、顺股市周期的。进一步,本文从最优货币政策的角度考察了我国货币状况指数的权重。根据最优货币政策规则,货币状况指数权重为0.302876,即利率上升1%相当于汇率下降0.30%,意味着利率变动的效果要小于汇率变动的影响。     

Credit Events and the Valuation of Credit Derivatives of Basket Type

Thispaper provides a simple model for valuing a credit derivativewhose payoff depends on the identity (or identities) of the first(or first two) to occur of a given list of credit events, suchas defaults. The joint survival probability of occurrence timesof credit events is formulated in terms of stochastic intensityprocesses under the assumption of conditional independence. Basedon the joint survival probability, we can easily obtain the pricingformulas of such credit derivatives under the risk-neutral valuationframework. When the default intensity processes follow the extendedVasicek model, closed-form solutions of the pricing formulasare given.     

我国资产价格与通货膨胀的关系研究——基于ARDL的技术分析

随着资产市场投资品种日益丰富,居民参与资产投资的程度不断深入,资产通过财富效应和投资效应对经济的影响越来越大,资产价格对一般物价水平的影响不断增强,因此资产价格波动是否会影响通货膨胀率就成为当前理论和实务界关注的焦点。为了检验我国资产价格与通货膨胀的关系,本文选择股票、汇率、房地产价格以及其他影响通货膨胀的因素,运用ARDL模型对我国资产价格和通货膨胀的关系进行经验分析。经验分析结果表明:资产价格波动影响通货膨胀,但各因素对通货膨胀的影响差异较大,即房地产价格和汇率两个指标作用显著,股票作用较弱。     

企业智力资本计量问题研究

企业智力资本计量是目前国内外理论界和实业界正在探索的一个热点领域。迄今已初步形成了一些计量模式和方法，但这些模式和方法存在许多缺陷。因而很有必要在此基础上，进一步探索更为科学的计量模式和方法。从企业价值创造机理来看，可以采用“动态四分法”对智力资本进行科学地分类，然后进行计量与估价，进而得出一种由识别、诊断和结果构成的三步式的企业智力资本计量的框架结构。     

长春市水生态系统服务价值核算及其动态变化

运用生态学和经济学方法进行了长春市水生态系统服务价值核算及其动态变化分析。结果表明,2010年长春市水生态系统服务总价值为17.80亿元,其中,资源功能价值(生物生产、水分供给、释放氧气)为10.42亿元,占58.54%;环境功能价值(污染净化、调蓄洪水、固定碳、养分积累、生物多样性保护)为6.55亿元,占36.80%;人文功能价值(旅游、健康)为0.83亿元,占4.66%。与1990年和2000年相比,长春市2010年水生态系统的资源功能价值所占比例升高,环境功能价值所占比例下降,人文功能价值所占比例升高。在城市发展过程中,不仅要科学利用水生态系统资源功能价值,还应进一步重视其环境功能价值和人文功能价值的实现。     

Measuring the consumer benefits of improving farm animal welfare to inform welfare labelling

Policy makers in the European Union are envisioning the introduction of a community farm animal welfare label which would allow consumers to align their consumption habits with their farm animal welfare preferences. For welfare labelling to be viable the market for livestock products produced to higher welfare standards has to be sufficiently segmented with consumers having sufficiently distinct and behaviourally consistent preferences. The present study investigates consumers’ preferences for meat produced to different welfare standards using a hypothetical welfare score. Data is obtained from a contingent valuation study carried out in Britain. The ordered probit model was estimated using Bayesian inference to obtain mean willingness to pay. We find decreasing marginal WTP as animal welfare levels increase and that people’s preferences for different levels of farm animal welfare are sufficiently differentiated making the introduction of a labelling scheme in the form of a certified rating system appear feasible.     

Inconvenience cost of mobile communication failure: The case of South Korea

Mobile communication failure can occur when mobile traffic exceeds the manageable level. This depends on frequency bandwidth. Mobile communication failure causes inconveniences in a user's daily life that lead to social and economic damage. To address this issue, mobile telecommunications companies deploy additional bandwidths and develop new technologies, but these are costly strategies. This study applies a spike model based on a contingent valuation method (CVM) to measure the inconvenience cost resulting from mobile communication failure. The mean monthly willingness-to-pay (WTP) to avoid communication failure per user is estimated to be KRW 898.14 (USD 0.80) over a period of five years in our study. The inconvenience cost borne by the population is estimated to be KRW 2.97 trillion (USD 2.61 billion). Users experiencing greater frequency of communication failure are found to be willing to pay more to avoid the inconvenience. When excluding respondents citing zero-WTP, the mean WTP per user was calculated to be KRW 3426.41 (USD 3.01). Data traffic usage and frequency at which communication failure is experienced are variables that exhibit statistically significant effects on WTP to avoid mobile communication failure. Overall, estimation results show that a price discrimination based on data traffic usage or quality can be considered by mobile telecommunications companies and regulators to address the issue of data traffic inducing mobile communication failure.     

A model of medium term exchange rate forecast in an open economy The case of the mexican peso

Keynes (1930) and Samuelson (1965) proposals open the possibility of matching predictability and efficiency, as evidenced by the seminal study by Fisher (1930). Recent findings suggest that the foreign exchange market gradually incorporates relevant information allowing the formation of prices in a rational manner but not randomly. Models of exchange rate by term based on asset valuation suggest that the inclusion of risk in the spot rate increases the degree of predictability. The results show that after incorporating an accurate measure of risk, predictability of medium term foreign exchange rate increases.     

The determinants of the volatility of returns on cross-border asset holdings

Using both panel and cross-sectional models for 28 industrialized countries observed from 2001–2009, we report a number of findings regarding the determinants of the volatility of returns on cross-border asset holdings (i.e., equity and debt). Greater portfolio concentration and an increase in assets held in emerging markets lead to an elevation in earning volatility, whereas more financial integration and a greater share held in Organization for Economic Cooperation and Development countries and by the household sector cause a reduction in the return volatility. Larger asset holdings by offshore financial corporations and non-bank financial institutions cause higher market volatility, although they affect volatility in the equity and bond markets in the opposite way. Overall, both panel and cross-sectional estimations provide very similar results (albeit of different magnitude) and are robust to the endogeneity problem.     

Monetary policy,doubts and asset prices

Asset prices and the equity premium might reflect doubts and pessimism. Introducing these features in an otherwise standard New-Keynesian model changes optimal policy in a substantial way. There are three main results: (i) asset-price movements improve the inflation-output trade-off so that average output can rise without much inflation costs; (ii) a “paternalistic” policymaker – maximizing the expected utility of the consumers under the true probability distribution – chooses a more accommodating policy towards productivity shocks and inflates the equity premium; (iii) a “benevolent” policymaker – maximizing the objective through which decisionmakers act in their ambiguous world – follows a policy of price stability.
