Extant literature on cost stickiness has focused on how firm-specific characteristics affect the asymmetric cost behavior. In this paper, we explore how a firm’s operating environment affects the firm’s cost stickiness. Specifically, we examine the effect of product market competition on cost stickiness since a firm’s investment and cost retention decisions partly depend on how the firm interacts with its rival firms in the product markets. Using two firm-level text-based product market competition measures extracted from management disclosures in firms’ 10-K filings (Li et al. in J Account Res 51(2):399–436, 2013; Hoberg and Phillips in Rev Financ Stud 23(10):3773–3811, 2010; J Polit Econ, 2015), we find strong evidence consistent with cost asymmetry increasing in competition after controlling for known economic determinants of cost stickiness. In additional analyses, we also find that the effect of product market competition on the degree of cost stickiness increases in firms’ financial strength, likely because management in financially stronger firms has more resources for investment expenditures in spite of a sales fall. We also find that cost stickiness is increasing in competition if management is optimistic about future demand, whereas competition is not associated with cost asymmetry if management is pessimistic about future demand. Finally, we find that the relationship between competition and cost stickiness, although statistically insignificant at conventional levels, is more pronounced for single-segment firms relative to multi-segment firms.  相似文献

The research objective is to examine empirically the relationship marketing and its successful implementation in Turkish Beverage Companies. Three scales were used to generate the data. Relationship marketing scale, environmental factors scale and company performance scale. Some of the variables in questionnaire used as control variables that reflect company-specific characters namely, company size, business type and sales volume. First the main effect of relationship marketing orientation on company performance was assessed, and then the moderating effect of environmental factors on the relationship between relationship marketing orientation and company performance was estimated by using multivariate techniques.  相似文献

This paper is devoted to the analysis of the estimation of the mean of a sensitive variable. The use of a randomized response (RR) procedure gives confidence to the interviewed that his privacy is protected. We consider that a simple random sampling with replacement design is used for selecting a sample. The behavior of the RR procedure, when ranked set sampling is the design used, is developed under three different ranking criteria. The usual gain in accuracy associated with the use of ranked set sampling is exhibited only by one of the designs. The behavior of the models is illustrated using data provided by a study of samples of persons infected with AIDS.  相似文献

Consider the problem of discriminating between two rival response surface models and estimating parameters in the identified model. To construct designs serving for both model discrimination and parameter estimation, the M γ-optimality criterion, which puts weight γ (0≤γ≤1) for model discrimination and 1 − γ for parameter estimation, is adopted. The corresponding M γ-optimal product design is explicitly derived in terms of canonical moments. With the application of the maximin principle on the M γ-efficiency of any M γ'-optimal product design, a criterion-robust optimal product design is proposed.  相似文献

This research has been made to assess the effects of the characteristics of bread wheat quality on the prices in the Turkish bread wheat market. A hedonic price model was used to analyze factors affecting the variability in bread wheat prices. Results indicate that prices received by bread wheat producers reflect the presence of basic quality characteristics of bread wheat. According to the research consequences, the hectoliter and sedimentation are the major factors that have the greatest effect and influence on Turkish bread wheat market in respect to the quality aspects. The study shows that the five regions in Turkey, which have been chosen as the research area and are important in bread wheat production, have differences in terms of bread wheat quality characteristics.  相似文献

This study explores the formation of relationship quality and online purchase intention in the service context of tourism, and a model is also introduced. This study tries to conceptualize a model based on a mediating mechanism of relationship quality that may be applied to understand online purchase intention in tourism. Learning the critical role of relationship quality in e-tourism can guide tour service providers to design different strategies for different online customers, and consequently achieve high customer online purchase to tourist service and product. In the proposed model of this study, the perceived incentive, perceived service quality, perceived ease of purchasing and perceived usefulness influence customer online purchase intention indirectly via the mediation of relationship quality. Additionally, five propositions are derived accordingly based on the proposed model and literature review. Finally, discussion, limitation and future research are also provided.  相似文献

That survey research is error prone is not a new idea and different varieties of non-sampling error have been investigated in the literature as well as consideration being given in many statistics textbooks to the issue of sampling error. The paper here considers research upon corporate environmental reporting. It compares information provided by corporate environmental reports with information that survey respondents claim their organization’s environmental report contains. This enables the accuracy of the claims to be assessed. Consideration is given to two different industries the Water industry and the Energy industry. Errors due to inaccurate reporting by survey respondents are shown to be relatively infrequent and respondents appear just about as likely to claim they report information that they do not, in fact, report as to fail to indicate that they report information that is, in fact, actually reported.  相似文献

In this paper, we analyze a model where individuals from finite populations are repeatedly drawn to play a finite game and in every period choose a weakly better reply to a sample distribution from a finite history of past play. For all finite games and sufficiently incomplete information, we prove convergence to minimal sets closed under better replies. This result complements previous findings in a deterministic continuous-time framework and implies convergence to strict Nash equilibria in many well-known classes of games.  相似文献
