Japanese Equity Market Response to U.S. Administered Protection Decisions

The standard capital market event study is used to measure Japanese firm-specific effects resulting from action taken by the US in response to alleged dumping of Japanese imports in US markets. Empirical findings are that winners and losers in the process differ predictably from each other and from the market in the way that Japanese investors view them, with differences being most pronounced at the petition filing date and the final stages of both the ITC and Department of Commerce decisions. © 1997 John Wiley & Sons, Ltd.

Selective Response to Questions on Delinquency*

In the German General Survey 2000 (ALLBUS), the so-called ‘Sealed Envelope Technique’ (SET), was utilized to obtain data on an individuals’ self-admitted delinquency. The focus of this article is to discover, particularly, the reason respondents refused to fill in this confidential questionnaire in spite of the guaranteed anonymity. From a theoretical perspective of subjective expected utility, the assumption is that respondents are interested in maximizing benefits and avoiding social costs in the interview situation. Consequently, responses provided are optimal realizations of the respondents’ interest. Furthermore, the respondents’ intellectual capacity in understanding the questions, the SET applied, the interviewer characteristics, and aspects of the interview situation, were presumably responsible for refusals on sensitive questions. The ALLBUS 2000 data confirm these hypotheses. The selectivity of self-reported delinquency on matters concerning fare avoidance and tax evasion also resulted in biased model estimators of determinants regarding anticipated future delinquency. Mail survey is one supported view on improving data quality in self-admitted acts of delinquency. However, before firm conclusions can be drawn, more empirical data is needed on the processes and mechanisms involved in a respondents refusal to answer questions on delinquency. * An empirical assessment on the effectiveness of the ‘Sealed Envelope Technique’ for self-admitted delinquency through the utilization of the German General Social Survey 2000 data.

Using Quick Response to manage the material flow

The long-awaited "paperless society" now truly appears to be within our grasp. Quick Response will reduce the mounds of paper on which we depend and minimise the time and expense needed to satisfy customers' demands/requirements. Quick Response will accomplish this while keeping inventory level at a minimum. Quick Response will significantly increase the bottom line.     

深圳成份指数样本股调整的市场反应研究——基于股价和成交量的分析

本文通过研究1997年至2002年深圳成份指数样本股调整对新入选样本股股价及其成交量的影响发现:第一,1997年新纳入深成指样本股的公司股价在调整日没有显著提高,但在调整日前存在显著为正的累积超常收益。第二,1999年至2002年新入选的指数样本股股价在调整当日显著上扬,且股价的上涨是持久的。①第三,1999年至2002年新入选的指数样本股在调整当日成交量显著放大,但在随后的20天成交量则逐渐萎缩,并低于正常成交量。进一步的研究表明,新样本股的Tobin s Q值与其调整当日所获得超常收益率呈显著的反向关系。结合中国指数基金的发展现状,本文认为,公司入选深成指向市场传递了新信息,即支持“信息假说”。

How to Improve the Efficiency of Randomised Response Designs

This paper describes ways to maximise the efficiency of randomised response designs. When randomised response designs become more efficient their value as a tool to study sensitive topics will increase. An overview of the literature shows that when sensitive or incriminating topics are studied, the overall results of randomised response studies are more valid than the results of direct question designs. This positive effect is small, however, and randomised response designs are known to be less efficient than direct question designs, making it necessary to recruit larger samples. In this paper the efficiency of six randomised response methods (Warner’s design, both forms of the unrelated question technique, the forced response technique, Moors’s design and Mangat’s improved model) will be compared relative to direct question designs. Using the right design parameters we can make randomised response studies up to twice as efficient. The forced response method and a special form of the unrelated question design are the most efficient designs until now.
