如何恪守理性投资是每个投资者面临的难题。而神经经济学的一些新发现可以帮助你在解决这个难题时做得更好有时候,你会冲动地买进一只危险的股票。有时候,你的投资正在不停地贬值,可你就是没法卖出它。还有的时候,你明明知道自己该为退休做更充分的准备,但就是无法恪守自己的计划。对绝大多数投资者而言,这些不理智、短视的决定往往都是下意识的行为:就像看到蟑螂马上用报纸去打一样。但是,新诞生的神经经济学 (neuroeconomics)这个学科可以帮助投资者们学会如何抵制他们这种自我毁灭的倾向。     

Issues in measuring a monthly house price index in New Zealand

The sale price appraisal ratio (SPAR) method, which takes the ratios of the current house prices and their previous assessed values to construct an index, has been applied in New Zealand since the 1960s. This paper uses housing market transaction data for 12 cities in New Zealand (1994–2004) to develop monthly SPAR house price indices. These indices were subjected to a variety of statistical tests and benchmarked against the comparable monthly quality controlled weighted repeat sales indices. Finally, the paper provides some useful suggestions for future research based on the SPAR index and other alternative house price indices, such as the assessed value (AV) method.     

Transparency in the Procurement of Public Works

The construction contract bonding system is used worldwide to protect the owner of a project against the risk of non-performance by the contractor. There is a close relationship between the construction contract bonding system and transparency in public works, which policy-makers and officials need to be more aware of. There are mainly three systems in use, which the authors have analysed in depth. Each of the three models has a different influence on transparency in public works: the 'high penalty conditional model' is considered the most functional model in improving transparency, the 'low penalty unconditional model' does not contribute very much to improving transparency, while the 'substitute contractor model' can lead to greater opportunities for corruption on the contractor's side.     

An Exploratory Study of the Effect on Forecast Accuracy of Using Different Geographic Segment Data Sources

The specific research question this study investigates is whether or not model-based earnings forecasts utilizing COMPUSTAT's country specific geographic segment data produce more accurate earnings forecasts than model-based forecasts utilizing data from actual geographic segment footnotes. This study compares the accuracy of earnings forecasts from models using the geographic segment information in actual geographic segment footnotes to the accuracy of earnings forecasts from models using the geographic segment information in the COMPUSTAT business segment tape. Evidence collected in this study indicates that geographic segment data provided in the COMPUSTAT business segment data base appears to make it possible to more accurately predict sales than does the geographic segment data provided in the same companies' actual geographic segment footnote.     

TOWARDS A BROADER UNDERSTANDING OF MEAT DEMAND — PRESIDENTIAL ADDRESS

This paper sets out meat consumption trends in the United Kingdom and within other EU countries over the past 40 years; it shows that whereas in the UK meat consumption has only increased by a small amount, for other EU countries it has almost doubled. In analysing the data in more detail, it is apparent that ‘non-price/income’ factors have been playing a more important part both for the UK and other EU countries. It is true that in recent years there has been much more published empirical work on the effect of different attitude, demographic and structural factors on meat demand; commercial and Governmental organisations have also been collecting a significant amount of relevant unpublished data. However, there has not been much recent progress on integrated approaches which combine the analyses of the consumer behaviourist with those of the economist. The paper concludes by stating that this is an area of growing importance for the food industry and those interested in analysing food demand trends. Agricultural economists should therefore get more involved in it.     

Forced technology transfer and China

Innovation is the most important competitive advantage of the United States. However, the infringement of intellectual property and the forcing of US firms to transfer technology to foreign firms have become increasingly important issues in recent years. This article discusses the implications of China's forced technology transfer regime.     

Microaggression,anxiety, trigger warnings,emotional reasoning,mental filtering,and intellectual homogeneity on campus: A study of what students think

College campus life is changing based on pressures to create safe environments for students to learn. Much of this change has been outlined in an article by Lukianoff and Haidt entitled “The Coddling of the American Mind.” The authors of the present article asked 188 students from two universities if microaggressions, trigger warnings, emotional reasoning, and mental filtering are prevalent on campus and whether colleges are promoting these concepts. The results show that the majority of students believe that universities must change the way these concepts are addressed to prevent intellectual homogeneity and to adequately prepare them for their business professions.     

The Rise and Stall of a Fair Trade Pioneer: The Cafédirect Story

This is a case study investigating the growth of fair trade pioneer, Cafédirect.

We explore the marketing, networks and communications channels of the brand which have led to rapid growth from niche player to a mainstream brand. However, the company is experiencing a slow down in its meteoric rise and we question whether it is possible for the company to regain its former momentum with its current marketing strategy.     

Do Employers' Responses to Crises Impact Men and Women Differently? Firm‐level Evidence from Indonesia

Do employers' responses to crises impact men and women differently? Using manufacturing census data from Indonesia this paper assesses gender differences in the impact of the East Asian crisis and to what extent these were due to differential treatment of men and women within firms and gender sorting across firms that varied in their exposure to the crisis. On average, women experienced higher job losses than their male colleagues within the same firm. However, the aggregate adverse effect of such differential treatment was more than offset by women being disproportionately employed in firms hit relatively less hard by the crisis. The null hypothesis that there were no gender differences in wage adjustment is not rejected.
