The changing nature of financial disclosure in Japan

This paper investigates whether Japanese companies listed on the Tokyo Stock Exchange (TSE) altered their voluntary accounting disclosure behavior over the period of the 1990s. It implicitly tests for whether the collapse of Japan's “Financial Bubble” in the late 1980s altered the incentives of Japanese managers to be more forthcoming about corporate information. Previous research on Japanese disclosure practices highlights the “secretive” nature of Japanese managers and suggests that cultural preferences strongly discourage disclosure. Our findings suggest that Japanese disclosure practices are sensitive to economic conditions.     

Nonparametric inference on multivariate versions of Blomqvist’s beta and related measures of tail dependence

We consider nonparametric estimation of multivariate versions of Blomqvist’s beta, also known as the medial correlation coefficient. For a two-dimensional population, the sample version of Blomqvist’s beta describes the proportion of data which fall into the first or third quadrant of a two-way contingency table with cutting points being the sample medians. Asymptotic normality and strong consistency of the estimators are established by means of the empirical copula process, imposing weak conditions on the copula. Though the asymptotic variance takes a complicated form, we are able to derive explicit formulas for large families of copulas. For the copulas of elliptically contoured distributions we obtain a variance stabilizing transformation which is similar to Fisher’s z-transformation. This allows for an explicit construction of asymptotic confidence bands used for hypothesis testing and eases the analysis of asymptotic efficiency. The computational complexity of estimating Blomqvist’s beta corresponds to the sample size n, which is lower than the complexity of most competing dependence measures.

Demand chain management in manufacturing and services: web-based integration, drivers and performance

This paper investigated the relationship between Internet-enabled supply chain integration strategies and performance in manufacturing and services. It summarizes the literature on demand and supply integration and describes four web-based strategies. A stratified random sample was collected from UK manufacturers and services, and there was strong evidence that demand chain management (DCM) led to the highest performance in manufacturing, but few signs of DCM in services. Manufacturers and services relying on only web-based demand or supply integration outperformed their low integration counterparts, but lagged DCM in manufacturing. The study also investigated DCM adoption drivers and found that rational efficiency and bandwagon effects drove change. The findings have some important implications for theory as well as for manufacturing and service companies interested in improving their performance.     

我国货币政策有效性的实证研究

本文选择有关变量对我国2002-2007年间货币政策进行实证分析,发现2002年来我国的货币政策存在一定程度的失效.导致货币政策部分失效有诸多因素,主要有体制和政策两方面的原因.从体制方面来看,银行上市带来信贷扩张压力;从政策方面看,利率和汇率机制不够完善导致货币政策失效.针对失效原因,作者从加强政府体制建设、完善货币政策体系、搭配运用财政与货币政策、完善货币政策传导机制等四个方面提出了相应的政策建议.

Goodness-of-fit testing for varying-coefficient models

We construct an empirical process-based test to examine the adequacy of varying-coefficient models. A Monte Carlo approach is applied to approximate the null distribution of the test. Due to the use of the Monte Carlo test procedure, beyond the desired features that are shared by the existing empirical process-based tests, our test is self-invariant, which overcomes the difficulty of estimating the variance of the test. Simulations are provided to illustrate our methodology.     

我国公司财务弹性与公司价值的研究——来自食品类上市公司的经验数据

本文在已有的研究的基础上,通过理论分析构建财务弹性指数构建的可能性,并对食品类上市公司构建了一个多维的财务弹性指标体系,通过对上述方法得出的财务弹性指数与公司价值进行多元回归分析,进一步探究财务弹性与公司价值之间的关系.研究表明,食品类上市公司财务弹性指数整体偏低,通过对财务弹性指数进行多元回归发现,财务弹性指数与公司价值呈正相关,保持有效的财务弹性水平有利于公司价值的提升.
