As a major global exchange, the Stock Exchange of Hong Kong (SEHK) only requires semi-annual reporting whereas other major exchanges including the ones in Chinese mainland require quarterly reporting. We argue against the traditional view that higher reporting frequency is necessarily more beneficial. The decision on reporting frequency depends on how the information is being processed by the recipient traders and the results are not obvious. Using a sample of Chinese companies duallisted in both China A share market and SEHK (AH shares) as the experimental group and mainland’s companies listed on SEHK (H shares) only as the control group, we apply the difference-in-difference (DID) method to investigate the impacts of reporting frequency on stock information quality. The results suggest that after China A share market require quarterly financial reporting for all listed companies in 2002, the information asymmetry of the H tranche of AH stocks increases. Different from prior studies, the results suggest a negative association between stock information quality and financial reporting frequency. We argue that the increased information asymmetry in the H tranche is caused by the noise spilled over from the A tranche. We conduct multivariable GARCH tests and find evidence supporting this conjecture. 相似文献

This paper analysed the validity and reliability of the revised tourist ecological orientation (RTEO) scale. There are relatively few studies in the area of the ecological behaviour of tourists and, therefore, RTEO and other scales should be taken into account in future tourism research. This study is based on a sample of 461 golf tourists. A double analysis was carried out: (1) a qualitative analysis through expert opinion and (2) a quantitative analysis through the partial least squares approach. The results suggest that the RTEO scale is a brief, simple and reliable scale of environmental actions. 相似文献

This study investigates whether major USDA reports still provide important news to changing crop markets. The news component of each report, or market “surprise,” is measured as a difference between the USDA estimate and its private expectation in corn, soybeans, and wheat markets. Changes in the relevance of USDA information are assessed by examining changes in the magnitude of market surprises and shifts in the futures price reaction to these surprises, which isolates the impact of each report. The stable size of market surprises over time suggests that competition from alternative data sources has not reduced the news component of USDA crop reports. Increasing price reaction to most reports, including those facing competition from alternative information sources, suggests that value of public information may be enhanced in uncertain markets affected by structural changes. 相似文献

The U.S. egg industry has been moving rapidly towards “cage-free” aviary housing as an alternative to conventional cages for hens. A choice experiment was used to evaluate the U.S. public’s willingness to pay (WTP) for egg attributes including housing system, color, size, and certifying agency. A significant difference in WTP for hen housing systems was found using video information treatments describing hen housing systems. When respondents were shown videos of egg production systems, they were indifferent between cage-free aviary and the alternative enriched colony hen housing system whereas with no video information the respondents clearly preferred the cage-free system. Results point towards potential public misunderstanding of the costs and benefits associated with the “cage-free” egg label designation and highlight potential discrepancies between industry commitments and informed consumer preferences. 相似文献

Food safety is a very important topic in China. We investigate Chinese consumers’ preferences and willingness to pay (WTP) for food traceability using a choice experiment. Given that consumers’ trust in the food system may affect their preferences and WTP, we also assess the interaction between consumers’ trust in government’s supervision of food safety and food labels and consumers’ preferences for traceable food products. Using data collected from a choice experiment on Fuji apples in a face-to-face survey in six Chinese cities, the results show that (i) consumers are willing to pay for traceable food but their valuations can differ upon the degree of their trust in government’s supervision of food safety and food labels; (ii) consumers are willing to pay for traceability with strong evidence of preference heterogeneity; (iii) government is not the most trusted safety inspection and certificate authority as found in prior studies using animal food products in China. 相似文献

环境规制、技术创新与中国火电行业的效率提升 总被引:19,自引:0,他引:19
基于效率的视角,本文对2004年中国30个省(自治区、直辖市)火电行业的环境规制进行分析。首先利用三阶段DEA模型排除经营环境与统计噪音对中国火电行业效率的影响,然后从非规制、弱规制、强规制三个层次分析环境规制程度与中国火电行业效率的关系。实证结果表明,环境规制可以提升中国火电行业整体的效率水平,总体上存在技术创新激励效应,但并非适用各个地区。最后本文根据环境规制与技术效率的关系,将中国各地区火电行业的发展模式划分为内力驱动环境友好型、环境弱友好型和外力推动环境友好型三种,并给出各自适应的规制建议。 相似文献

Leslie A. Hayduk 《Quality and Quantity》2006,40(4):629-649
Bentler and Raykov (2000, Journal of Applied Psychology 85: 125–131), and Jöreskog (1999a, http://www.ssicentral.com/lisrel/column3.htm, 1999b http://www.ssicentral. com/lisrel/column5.htm) proposed procedures for calculating R 2 for dependent variables involved in loops or possessing correlated errors. This article demonstrates that Bentler and Raykov’s procedure can not be routinely interpreted as a “proportion” of explained variance, while Jöreskog’s reduced-form calculation is unnecessarily restrictive. The new blocked-error-R 2 (beR 2) uses a minimal hypothetical causal intervention to resolve the variance-partitioning ambiguities created by loops and correlated errors. Hayduk (1996) discussed how stabilising feedback models – models capable of counteracting external perturbations – can result in an acceptable error variance which exceeds the variance of the dependent variable to which that error is attached. For variables included within loops, whether stabilising or not, beR 2 provides the same value as Hayduk’s (1996) loop-adjusted-R 2. For variables not involved in loops and not displaying correlated residuals, beR 2 reports the same value as the traditional regression R 2. Thus, beR 2 provides a conceptualisation of the proportion of explained variance that spans both recursive and nonrecursive structural equation models. A procedure for calculating beR 2 in any SEM program is provided. 相似文献

Experimental and empirical evidence documents instances where the presence of an inferior option in a menu increases the attractiveness of the better options from that menu and thus distorts the normative ranking across menus. We analyze the case when in addition to this so called context-effects bias there is also a concern for flexibility, in the spirit of the literature initiated by Kreps (1979) and Dekel et al. (2001). Since the context-effects bias and the desire for flexibility both increase the inclination of a decision maker to choose larger menus, our analysis allows the disentangling of the effect of the behavioral bias from the effect of the rational desire from flexibility. We find a weak condition on the set of ex post preferences under which the two effects are identifiable. We show that our representation is essentially unique. From a methodological viewpoint, our paper provides a novel technique of identifying probabilities on the state space of subjective uncertainty introduced by Dekel et al. (2001) when this state space is infinite. This method renders the infinite state space essentially finite with respect to a certain salient property. 相似文献
