Bayesian multiple imputation (MI) has become a highly useful paradigm for handling missing values in many settings. In this paper, I compare Bayesian MI with other methods – maximum likelihood, in particular—and point out some of its unique features. One key aspect of MI, the separation of the imputation phase from the analysis phase, can be advantageous in settings where the models underlying the two phases do not agree. 相似文献

This article examines the earnings performance of nontraditional assets allowed to thrifts since the early 1980s. It uses the statistical cost accounting methodology developed by Hester and Zoellner to estimate average returns on thrift portfolio investments for the years ending June 30, 1987 and June 30, 1988. Results show that average returns on land loans, service corporation investment, real estate investment, and commercial loans were significantly lower than returns on more traditional assets. The results are far more pronounced at capital deficient institutions, lending support to the hypothesis that they used nontraditional investments as a means of exploiting the deposit insurance system. Returns on nontraditional assets are significantly affected by geographic factors, even for well capitalized institutions. The article concludes with an evaluation of the reimposition of portfolio restrictions on thrifts by the Financial Institutions Reform, Recovery, and Enforcement Act of 1989.The views expressed in this paper are those of the authors and do not necessarily represent the views or opinions of the Federal Housing Finance Board, the Board of Governors of the Federal Reserve System, or the Federal Deposit Insurance Corporation. George Benston, Tom Fomby, Allen Berger, John Wolken, and anonymous referees made numerous constructive suggestions. 相似文献

Asian brands have often struggled to develop quality images. The visual aspects of branding have received little attention on how they might be used to strengthen brand perceptions in Asia. Guidelines for designing visual brand stimuli are developed using evaluations of logos in China and Singapore. There is a significant relationship between design and the responses companies seek, including positive affect, perceptions of quality, recognition, consensus in meaning, and feng shui. How designs are perceived, and their effect on consumer responses, were similar between China and Singapore. Companies are encouraged to leverage design to strengthen their brands. In particular, they should select logo designs that are elaborate, natural, and harmonious as these created positive affect and quality perceptions, clear meaning, true recognition, and feng shui. Many of these relationships hold in the United Sates as well, implying that the visual aspects of brand strategies may accomplish companies' goals across international borders. 相似文献

The Internet furore over Intel's flawed Pentium chip provides an important case study of the ethical ambiguity of internet communications and the legitimacy of certain forms of "electronic activism". Joseph Badaracco, Jr., is John Shad Professor of Business Ethics at the Harvard Business School and his co-author is a former Research Associate at Harvard and currently on the editorial staff of Inc . magazine. 相似文献

Since the year 2000, silicon intellectual property (SIP), which can minimize the gap in ‘design productivity’ that exists with systems-on-chip (SOC), has become one of the most important factors in the development of integrated circuit (IC) products in the SOC era. Although SIP is very important for IC industry development, complicated business, technical as well as legal issues inside SIP transactions have hindered successful transactions and the integration of SIPs into SOCs. Thus, web-based SIP e-Commerce mechanisms, called SIP Malls, have emerged, aiming to resolve complex SIP issues. To maintain its leading position and competitiveness in the World's IC industry, as well as the value added by SOC products in Taiwanese IC firms, the Taiwanese government has developed SIP Malls, using innovation policy tools. However, the Taiwanese SIP Mall industry remains immature. No existing Taiwanese SIP Malls generate a profit or account for a significant share of worldwide SIP transactions. This research will develop an analytical framework for defining an innovation policy portfolio that aims to develop Taiwan's SIP Mall industry, so that it will enhance the value added of SIP Malls and, thus, the nation's competitiveness in the SIP and IC industries, something which already has become one of the Taiwanese government's major concerns. The industry innovation requirements (IIRs) are summarized using the Delphi method. Meanwhile, the major IIRs identified by Decision Making Trial and Evaluation Laboratory (DEMATEL) are introduced. After the IIRs are derived, the relationships between the IIRs and innovation policy tools are derived by Grey relational analysis (GRA). Then, the innovation policy tools are clustered, based upon the Grey grades derived by GRA. Finally, reconfigured innovation policy portfolios are presented for the Taiwanese government's policy definition. The results demonstrate that developing an innovative policy portfolio that includes scientific, technical, educational, public enterprise, information, legal and regulatory, financial, and taxation policy tools will be the most necessary step towards developing Taiwan's SIP Mall industry. 相似文献

In the last few years bipartisan support for legalizing drugs has grown to a surprising level. Because of the lack of involvement of the business community in this debate, we surveyed the human resource managers of 127 firms about their perceptions of the effects of legalization. Their responses were uniformly negative, with expectations that drug use, absenteeism, worksite crime, and liability costs would increase, while the quality and quantity of work would decline. They also forecast increases in drug testing, performance monitoring, and education and rehabilitation programs as a result. 相似文献

A path analytic model of store loyalty involving self-concept,store image,geographic loyalty,and socioeconomic status 总被引:2,自引:0,他引:2
A model is introduced which posits that store loyalty is primarily determined by store-image evaluation and shopping-complex
loyalty. Store image-evaluation, in turn, is hypothesized to be determined, to a major extent, by self-image/store-image congruity,
and shopping-complex loyalty by area loyalty and socioeconomic status. The model was tested using a path analytic procedure
and the results were consistent with the model. A replication study was attempted and the results reinforced the validity
of the proposed model. 相似文献
