Paul Krugman's essay “Who Was Milton Friedman?” seriously mischaracterizes Friedman's economics and his legacy. In this paper, we provide a rejoinder to Krugman on these issues. In the course of setting the record straight, we provide a self-contained guide to Milton Friedman's impact on modern monetary economics and on today's central banks. We also refute the conclusions that Krugman draws about monetary policy from the experiences of the United States in the 1930s and of Japan in the 1990s.  相似文献

We examine the value relevance and reliability of reported goodwill and identifiable intangible assets under Australian GAAP from 1994 to 2003; a period characterised by relatively restrictive accounting treatment for goodwill and relatively flexible accounting treatment for identifiable intangible assets. Our findings, using an adaptation of Feltham and Ohlson (1995), suggest that for the average Australian company the information presented with respect to both goodwill and identifiable intangible assets is value relevant but not reliable. In particular, goodwill tends to be reported conservatively while identifiable intangible assets are reported aggressively.  相似文献

We present a trend‐based alternative to the standard first‐order autoregression model in persistence of profits studies. This is motivated by reservations over the interpretation of the standard model, and rests on a different concept of dynamic competition. A nine‐category taxonomy of long‐run persistence stereotypes is developed. Structural time series estimates are presented for a sample of UK companies. We find the null of long run competitive equilibrium not rejected in nearly a third of cases, but non‐eroding persistence to be present in around 60%.  相似文献

Limits to forecasting in personalized medicine: An overview   总被引:1,自引:1,他引:0  
Biomedical research is generating massive amounts of information about potential prognostic factors for health and disease. However, few prognostic factors or systems are robustly validated, and still fewer have made a convincing difference in health outcomes or in prolonging life expectancy. For most diseases and outcomes, a considerable component of the prognostic variance remains unknown, and may remain so for the foreseeable future. I discuss here some of the main problems in medical forecasting that pose obstacles to personalized medicine. Their recognition may help identify solutions to improve personalized prognosis, or at least understand and cope with the component of the future that we cannot predict. Much prognostic research is stuck at generating “publishable units”, without any interest in conclusively proving their worth, let alone moving them into real life applications. Information is reported selectively and reporting is deficient. The replication record of prognostic claims is poor. Even among replicated prognostic effects, few are convincingly shown to add much information besides what is already known through more simple, traditional measurements. There are few efforts to systematize prognostic knowledge. Most prognostic effects are subtle when traced to the molecular level, where most current research operates. Many researchers, clinicians, and the public are not appropriately educated to interpret prognostic information. We still have not even agreed on what the important health outcomes are that we want to predict and intervene for, and some subjectivity may be unavoidable. Finally, without concomitant effective, affordable, and non-harmful interventions, prognosis alone is of questionable value, and wrong prognosis or a wrong interpretation thereof can be harmful. The identification of these problems also suggests a roadmap on what could be done to amend them. Solutions include a systematic approach to the design, conduct, reporting, replication, and clinical translation of prognostic research; as well as the education of researchers, clinicians, and the general public. Finally, we need to recognize that perfect individualized health forecasting is not a realistic target in the foreseeable future, and we have to live with considerable residual uncertainty.  相似文献

Four problems occur in the scale development process: (a) defining the construct, (b) drawing items from multiple domains, (c) identifying dimensions, and (d) showing nomological validity. In order to minimize these problems, the authors propose a general hierarchical model (GHM) that provides an organizational structure for placing many of the individual difference constructs used in marketing and consumer behavior. Three principles, which were derived from the GHM, add to the current scale development paradigm: (a) Define and test the construct within a hierarchical network that includes antecedents and consequences, (b) define and test the construct's dimensionality, and (c) match the construct's items to its level in the hierarchical system. By using these steps in scale development, researchers can build more precise measures possessing higher levels of validity and reliability. © 2008 Wiley Periodicals, Inc.  相似文献

Hendee, John C., “Sociology and Applied Leisure Research,” ANNALS OF TOURISM RESEARCH, Volume II, No. 3, January/February, 1975, pp. 155–162 — The importance of leisure activity as a social problem is growing and sociological research is challenged to contribute more to leisure problem areas with public or industrial policy implications. Leisure researchers must adapt their product to the current goal-oriented, cost-effective, budgeting criteria to compete for public money. Thus, the future of leisure research may depend partly on riding the coattails of applied work which is more easily funded. Studies linking leisure activity to broader society and the mainstream of sociological research are encouraged and, for example, might focus on: identifying the social meaning of recreating, improved techniques for predicting future use of leisure time and demand for leisure facilities, patterns and benefits of leisure activity. Joint ventures combining sociology and professional schools with policy and applied interests could help alleviate the sociologist's often neglected task of developing policy implication. In short, an appeal is made for relevant leisure research so that growth in the field may be supported by the utility of results.  相似文献

This article examines the pricing of rental contracts for two types of renter households: those who are able to amass a large, up-front security deposit and those with little, or no, security to offer. Empirical tests are presented to suggest that, in dealing with renter households who have little, or no, security to offer, landlords earn at a similar rate of return as lenders who make riskier loans at a high interest rate to borrowers of dubious credit. The analysis suggests that this situation occurs in large part because of the problem of asymmetric information and moral hazard between landlords and renter households regarding the latter's use of the premises.  相似文献
