When handling missing data, a researcher should be aware of the mechanism underlying the missingness. In the presence of non-randomly missing data, a model of the missing data mechanism should be included in the analyses to prevent the analyses based on the data from becoming biased. Modeling the missing data mechanism, however, is a difficult task. One way in which knowledge about the missing data mechanism may be obtained is by collecting additional data from non-respondents. In this paper the method of re-approaching respondents who did not answer all questions of a questionnaire is described. New answers were obtained from a sample of these non-respondents and the reason(s) for skipping questions was (were) probed for. The additional data resulted in a larger sample and was used to investigate the differences between respondents and non-respondents, whereas probing for the causes of missingness resulted in more knowledge about the nature of the missing data patterns.  相似文献

Dutch glasshouse firms are facing the introduction of a system of tradable CO2 emission quotas. This paper employs a non‐parametric method for modelling tradable CO2 emissions of Dutch glasshouse firms. The method is capable of generating shifts in CO2 emissions across the sample of firms. Moreover, changes in volumes of outputs produced and inputs used are computed. Results show that firms using a conventional heating technology will be net purchasers of CO2 emissions, whereas firms using more advanced heating technologies will sell part of their emission quota.  相似文献

Abstract:  Auditors, as corporate insiders, have access to private information regarding the firm's financial and business opacity that is unavailable to outside investors. We test whether auditors price their knowledge of firm opacity in their audit fees by examining two competing hypotheses. The first states that higher audit fees may reflect the greater risk that the auditor faces in auditing an opaque firm. Under this hypothesis, market based measures of opacity will be positively correlated with higher fees. The second hypothesis states that firms buy reputational capital from their auditor by paying high fees in an attempt to improve the market's perception of the firm's transparency. In this case, higher audit fees are negatively correlated with market based measures of opacity. Our results are consistent with the first hypothesis, that auditors price opacity risk into their fees.  相似文献

When considering organization strategy‐making and execution from a learning perspective, the role of conversation and engagement is of critical importance, yet little research has been conducted in this area. Recent publications have suggested an increasing role for conversation and dialogue in strategic planning processes. The present study provides initial validity and reliability scores of an instrument for measuring individual conversation quality and engagement skills in a strategic planning context. Participants were managers (n = 204) from four organizations. Results indicate an instrument with highly accurate and consistent measurement scores. Implications for practice and future research are briefly discussed.  相似文献

Successful regional products, such as Florida oranges, Idaho potatoes and Parma ham, often have to compete against products passing themselves off as the authentic product using the exact same name. This unfair competition misleads consumers, discourages small‐ and medium‐sized enterprises (SMEs) from marketing products based on their region of origin, and may end up hurting rural economies. To protect consumers, and support SMEs and rural economies, many countries around the world have introduced regulations enabling SMEs to legally protect the names of their regional products. The success of these regulations largely depends on consumers’ appreciation of regional certification labels that inform consumers that the name of the regional product is protected and that it denotes the authentic product. To gain an understanding about consumers’ appreciation of regional certification labels, this paper investigates consumers’ image of these labels and proposes a model that relates this image to consumers’ willingness to buy and pay for protected regional products. The model is tested based on Regulation No. 2081/92 that was introduced by the EEC allowing European SMEs to protect their regional products and market their products with a protected‐designation‐of‐origin (PDO) label. Structural equation modelling results suggest that consumers’ image of regional certification labels consists of a quality warranty dimension and an economic support dimension, which positively relate to consumers’ willingness to buy and pay for the protected regional product. Protecting regional products and marketing them with regional certification labels may be beneficial for SMEs producing and marketing regional products. Policy and managerial implications are discussed.  相似文献

The internationalization of business is the subject of an extensivetheoretical literature as well as a growing number of historicalstudies. Historians have paid relatively little attention tothe development of multinationals in the service sector, andstudies about international publishing are especially scarce.This article discusses the early internationalization of twoDutch publishing firms, Kluwer (now Wolters Kluwer) and Elsevier(now Reed Elsevier) and confronts these case histories withthe evolutionary theory of internationalization. The Dutch casesunderline the important role of experience, knowledge and learningas well as of the national context in which companies develop.They also show that these factors allow for very different trajectoriesof internationalization within the same branch of business andthe same country.  相似文献
