Gain,Loss, and Two-State Modeling

Gain and loss, calculated from the upside and downside portions of return distributions, play a pivotal role in the two-state model. A two-state economy possesses a universal gain-loss ratio (G/L) for all assets that is related to the ratio of state prices and to the familiar risk-neutral probabilities. This paper derives many asset pricing properties in a two-state context and shows the role of gain and loss. Applied to bonds, for example, risky debt yields depend directly on both G/L and a bond's potential loss. Using S&P 500 data over a 72-year period, the market has priced an Arrow-Debreu security in the gain state at approximately $0.36, while the Arrow-Debreu security in the loss state has been priced at $0.61. Historically, the S&P 500's expected gain is about three times its expected loss.     

Logit Price Dynamics

We model retail price stickiness as the result of costly, error‐prone decision making. Under our assumed cost function for the precision of choice, the timing of price adjustments and the prices firms set are both logit random variables. Errors in the prices firms set help explain micro facts related to the size of price changes, the behavior of adjustment hazards, and the variability of prices and costs. Errors in adjustment timing increase the real effects of monetary shocks, by reducing the “selection effect.” Allowing for both types of errors also helps explain how trend inflation affects price adjustment.     

中美双边汇率对美国消费价格传递效应的实证研究

人民币升值的价格传递效果是近年来的一个研究热点。已有学者利用人民币汇率变动与关国对我国进口价格指数等数据进行研究,得出了人民币汇率变动的价格传递极低的结论。本文选择美国与我国贸易品相关性较高的消费品价格指数,利用2005年7月至2008年10月之间的月度数据,采用Johsen＆Juselius协整检验、误差修正模型分析汇改以来人民币汇率升值期间中关双边名义汇率变动的价格传递效应。研究发现中关双边名义汇率波动对美国消费物价的影响是显著的,长短期传递系数分别为O．1871、0．1917,并在此研究中得到几点政策启示。

On the Asymmetric U‐Shaped Relationship between Inflation,Inflation Uncertainty,and Relative Price Skewness in the UK

We investigate the asymmetric relationships between aggregate inflation and the second and third moments of the cross‐sectional distribution of relative prices using a modified Calvo pricing model with regime‐dependent price rigidities. Calibration experiments reveal that the inflation‐standard deviation and inflation‐skewness relationships exhibit U‐shaped asymmetries around the historical mean inflation rate. UK sectoral data support our results. We conclude that monetary policy should target an inflation rate proximate to the (common) minima of these nonlinear relationships and that core inflation measures should not be used for policy purposes as they exclude much of the information contained in the higher moments.     

从企业通胀预期看资产价格对物价水平的影响——基准模型与中国借鉴

企业作为市场经济的重要参与主体,其行为对物价水平有着显著影响,而受资产价格影响的企业通货膨胀预期是重要因素之一。综合运用理论分析与数理分析,对传导渠道进行研究发现：资产价格通过现有物价水平、企业对未来影响物价水平因素以及发生财务危机的预期使企业通货膨胀预期发生更大幅度的同向变化,进而使总需求正向变化,总供给负向变化,从而对物价水平产生正向的影响,且这种影响在发达国家更为明显。     

会计计量模式变革背景下货币与价格假设理论研究

货币与价格是与价值密切相关的两个概念,是商品经济的重要方面。描述商品经济环境离不开对货币与价格的描述。本文在系统地回顾、评述有关货币与价格基本假设,并结合马克思货币与价格相关理论的基础上,探讨了新会计准则中引入公允价值计量模式后,对于与货币与价格相关的基本假设,我国可以采用的两种可行的表述模式。     

More Facts about Prices: France Before and During the Great Recession

Using microprice data, we document new facts on price rigidity in France: (i) each month 20.1% of prices are changed, which compares to 24.1% in the United States—excluding sales, however, the fraction of prices modified each month is about the same in France and in the United States (around 17%); (ii) the distribution of price changes is quite dispersed; (iii) the frequencies of price increases and decreases contribute a lot to inflation variations, and price increases are more frequent in January (even when sales are excluded); (iv) sales contribute significantly to the volatility of inflation but play a minor role in the transmission of macroeconomic fluctuations to prices; and (v) during the Great Recession patterns of price adjustment were only slightly modified.     

Testing the bivariate mixture hypothesis using German Stock market data

According to the bivariate mixture hypothesis (BMH) as proposed by Tauchen and Pitts (1983) and Harris (1986, 1987) the daily price changes and the corresponding trading volume on speculative markets follow a joint mixture of distributions with the unobservable number of daily information events serving as the mixing variable. Using German stock market data of 15 major companies the distributional properties of the BMH is tested employing maximum-likelihood as well as generalised method of moments estimation techniques. In addition to providing a new approach for the pointwise estimation of the latent information arrival rate based on the maximum-likelihood method, we investigate the time-series properties of the BMH. the major results can be summarised as follows: (i) the distributional characteristics of the data (especially leptokurtosis and skewness in the distribution of price changes and volume respectively) cannot be explained satisfactorily by the BMH; univariate mixture models for price changes and trading volume separately reveal a possible specification error in the model; (ii) a univariate normal mixture model can account for the observed distributional characteristics of price changes; (iii) the estimated process of the latent information rate cannot fully explain the time-series characteristics of the data (especially the volatility clustering or ARCH-effects).     

The Coexistence of Distribution Systems When Consumers Are Not Informed

We attempt to explain the coexistence of two distribution systems when consumers are poorly informed about price distribution. The interaction of price dispersion and consumer search behavior is shown to affect the choice of marketing systems. We provide a necessary and sufficient condition for the coexistence as a long-run equilibrium. The market may observe the coexistence of the two agency systems regardless of the relative efficiency of agency types, or the domination by the less efficient agency system offering higher average price.     

The market price of risk and the equity premium: A legacy of the Great Depression?

By positing learning and a pessimistic initial prior, we build a model that disconnects a representative consumer's subjective attitudes toward risk from the high price of risk that a rational-expectations econometrician would deduce from financial market data. We follow Friedman and Schwartz [1963. A Monetary History of the United States, 1857-1960. Princeton University Press, Princeton, NJ] in hypothesizing that the Great Depression heightened fears of economic instability. We use a robustness calculation to elicit a pessimistic prior for a representative consumer and let him update beliefs via Bayes’ law. Learning eventually erases pessimism, but while it persists, pessimism contributes a volatile multiplicative component to the stochastic discount factor that a rational-expectation econometrician would detect. With sufficient initial pessimism, the model generates substantial values for the market price of risk and equity premium and predicts high Sharpe ratios and forecastable excess stock returns.     

浅析三个月以上Shibor的基准性及应用

Shibor的基准性需要有实际成交来验证。由于银行内在成交动力不足等因素,目前的中长期拆借成交量仍然偏小,此外,不同市场利率生成因素的内在差异也对中长期Shibor的基准性构成干扰。提高3个月以上Shibor的基准性,一方面要为扩大3个月以上信用拆借铺平道路,另一方面要理顺各市场之间的价格生成因素,推进各类产品与Shibor相挂钩的定价机制,建立以Shibor为基准的统一定价模式。     

Stochastic duration and fast coupon bond option pricing in multi-factor models

Generalizing Cox, Ingersoll, and Ross (1979), this paper defines the stochastic duration of a bond in a general multi-factor diffusion model as the time to maturity of the zero-coupon bond with the same relative volatility as the bond. Important general properties of the stochastic duration measure are derived analytically, and the stochastic duration is studied in detail in various well-known models. It is also demonstrated by analytical arguments and numerical examples that the price of a European option on a coupon bond (and, hence, of a European swaption) can be approximated very accurately by a multiple of the price of a European option on a zero-coupon bond with a time to maturity equal to the stochastic duration of the coupon bond. This revised version was published online in June 2006 with corrections to the Cover Date.
