Existing studies on bubbles have been mainly concerned with investigating the stationarity properties of stock prices and market fundamentals. We develop a new method of testing for bubbles that relates the bubble component of stock prices to the probability of bursting in the context of the Weibull distribution. There were several eruptions and subsequent collapses of seeming bubbles over the past three decades: 1987 (Black Monday), 2000 (information technology (IT) boom) and 2007 (housing market boom). Using US monthly data for the S&P 500 and NASDAQ series, we have found that the S&P 500 series contained an explosive bubble only during the boom of the housing market that occurred before the 2007 global economic crisis, and the NASDAQ market contained an explosive bubble during the surge of stock prices peaking in 1987 and 2007, although our stationarity tests fail to detect the bubbles. No bubble was found in both the S&P and NASDAQ series during the 2000 IT boom. Our evidence corroborates the criticism that the traditional unit root and cointegration tests may not be able to detect some important class of bubbles.  相似文献

We analyze the relatively new phenomenon of credit ratings on syndicated loans, asking first whether they convey information to the capital markets. Our event studies show that initial loan ratings and upgrades are not informative, but downgrades are. The market anticipates downgrades to some extent, however. We also examine whether public information reflecting borrower default characteristics explains cross‐sectional variation in loan ratings and find that ratings are only partially predictable. Our evidence suggests that loan and bond ratings are not determined by the same model. Finally, we estimate a credit spread model incorporating bank loan ratings and other factors reflecting default risk, information asymmetry, and agency problems. We find that ratings are related to loan rates, given the effect of other influences on yields, suggesting that ratings provide information not reflected in financial information. Ratings may capture idiosyncratic information about recovery rates, as each of the agencies claims, or information about default prospects not available to the market.  相似文献

Although the Internet is a convenient platform to conduct commercial transactions, consumers are disadvantaged in the online marketplace due to insufficient information about goods and services as well as business and transaction process, lack of access to redress and several other problems. The number of complaints regarding online transactions increased in Australia from 2001 to 2005, and the number of Internet‐fraud related complaints reported to Consumer Sentinel (USA ) also increased from 2003 to 2006. This, in turn, has undermined consumer trust and impeded the growth of e‐retailing as well as added to the fear among e‐consumers of falling prey to online fraud. In spite of this, the nature and effectiveness of e‐consumer protection has not been adequately studied, notwithstanding extensive research into other aspects of e‐retailing. This article examines (i) the level of awareness of the respondents in the survey in Australia of the current policy framework for addressing consumer protection about online shopping in terms of redress; and (ii) the behaviour of the two groups of respondents in this survey who have and have not encountered problems with online purchases. The findings suggest that most respondents are not aware of the following issues, namely (i) which organizations are involved in e‐consumer protection; (ii) government regulations and guidelines; (iii) industry codes of conduct; (iv) self‐regulatory approaches adopted by business; and (v) the activities of consumer associations to protect consumers in the online marketplace. The findings also show that most respondents would seek redress if they were unhappy with their online purchases and if they knew how to proceed, and that most of them would settle disputes directly with e‐retailers. Also, online shoppers who had encountered problems were more likely to continue purchasing via the Internet than online shoppers who had not encountered any problems. This suggests that respondents find that the benefits offered by e‐retailing outweigh the risks associated with it.  相似文献

This article discusses approaches to impact assessment of microfinance programmes through a survey of empirical literature and findings of an impact study of Khula Enterprise Finance, a South African wholesale finance institution that facilitates access to financial services by small, medium and microenterprises. The article notes that impact assessment has now opened up to the needs of a mix of stakeholders and a wide range of purposes. There has been a shift from a donor-driven approach to a practitioner-led approach that emphasises learning and improving practice. Nevertheless, findings of an impact study of Khula Enterprise Finance, a characteristically donor-driven type of study, indicate a positive impact on the beneficiaries of microfinance, especially women in rural areas where they are specifically targeted. Furthermore, the impact study shows that lower-income communities in rural areas have benefited less than their not-so-poor counterparts in the urban areas, an observation that is consistent with findings in other studies.  相似文献

The banana prawn component of Australia's Northern Prawn Fishery (NPF) is currently managed through the use of annually updated trigger catch rates as a means of achieving maximum economic yield (MEY) in the fishery, taking into account the estimated price and cost components for that season. The estimation of these target catch rates is based on the assumption of relative homogeneity of the fleet in terms of efficiency, productivity and cost structure. In this study, these assumptions are examined through the estimation of a stochastic production frontier. While technical efficiency varies between vessels, average efficiency is relatively constant over the fishing season. However, average productivity of the fleet increases, with smaller vessels (in terms of engine power) exiting the fishery earlier. This would likely increase the average cost of fishing towards the end of the season, with implications for setting the target catch rate. Based on a standard assumption as to the relationship between costs and vessel size, we find that the MEY target catch rates are most likely currently underestimated. However, the implementation of a precautionary minimum catch rate (which is above the MEY target catch rates for recent years) has maintained the fishery at a profitable level.  相似文献

This study examined American customers’ perceptions of values regarding dining experiences in Korean restaurants in the United States. Specifically, the effects of hedonic and utilitarian values on customer satisfaction and behavioral intentions were investigated. This study also examined the moderating effect of familiarity with Korean restaurants on the relationships among perceived values, satisfaction, and behavioral intentions. Overall, the results indicated that American customers valued the utilitarian aspects of Korean restaurants more than the hedonic aspects. Additionally, utilitarian aspects had a stronger impact on customer satisfaction and behavioral intentions than hedonic aspects. However, when considering customers’ familiarity level with the restaurants, hedonic aspects more effectively induced positive behavioral intentions in the low familiarity group, proving that familiarity has a moderating role. Conversely, utilitarian aspects appeared to be more influential in terms of the behavioral intentions of the high familiarity group. Theoretical and practical implications are also discussed.  相似文献

如何减小全球经济失衡的纠正对中国的冲击   总被引:2,自引:0,他引:2  
全球经济失衡的根本原因 全球经济失衡的明显特征是经常账户的失衡和长期利率偏低导致许多国家房地产价格的"泡沫性"上涨.对于这一现象的解释分为两个阵营.以即将成为美联储主席的伯南克为首的经济学家认为亚洲国家的高储蓄率导致全球性储蓄过剩,压低了长期实际利率.他们中有不少人把矛头指向中国,认为人民币缺乏灵活性使中国经常账户顺差近年来大幅上升,在固定汇率制下中国大量购买美元资产,为美国的贸易逆差"买单".但是,也有一些经济学家包括不少中国经济学家认为,美国财政赤字的恶化和前期的低利率政策大大降低了美国政府和家庭储蓄,是导致全球经济不平衡的根本原因.但是这种观点无法解释全球利率偏低这一现象,因为美国对于资本流入需求的增长应当推高而不是降低全球利率水平.  相似文献

Analysing Vietnam's rice export policy and recent export ban in the context of rising food prices, this study combines insights from a regionally‐disaggregated or ‘bottom‐up’ CGE model and a micro‐simulation using household data. Three main conclusions are drawn. First, although there is little impact on GDP, there are substantial distributional impacts across regions and households from different export policies and market conditions. Second, both rural and urban households, including poor households, benefit from free trade, even though domestic rice prices are higher. Finally, under free trade, relatively large gains accrue to rural households, where poverty is most pervasive in Vietnam.  相似文献

This paper shows how scale efficiency can be measured from an arbitrary parametric hyperbolic distance function with multiple outputs and multiple inputs. It extends the methods introduced by Ray (J Product Anal 11:183–194, 1998), and Balk (J Product Anal 15:159–183, 2001) and Ray (2003) that measure scale efficiency from a single-output multi-input distance function and from a multi-output and multi-input distance function, respectively. The method developed in the present paper is different from Ray’s and Balk’s in that it allows for simultaneous contraction of inputs and expansion of outputs. Theorems applicable to an arbitrary parametric hyperbolic distance function are introduced first, and then their uses in measuring scale efficiency are illustrated with the translog functional form.  相似文献
