A retail store is a multi-sensory environment filled with messages to tempt customers into making unplanned purchases. The purpose of this field study was to examine the interplay between three factors claimed to precede and influence unplanned purchases: store familiarity, visual attention, and navigational fluency (the subjective ease of navigating). Eye-tracking recordings and post-study questionnaires from 100 grocery store shoppers showed that store familiarity was positively associated with navigational fluency. However, customers' levels of dynamic gaze behavior (a frequent, widely distributed viewing pattern) moderated this effect. Dynamic gaze behavior significantly predicted navigational fluency among customers with low and moderate store familiarity, but not among customers familiar with the store. These findings challenge the formerly held assumption that store familiarity automatically implies navigational ease, and store unfamiliarity implies navigational difficulty. The results have implications for navigational aspects in stores.  相似文献

Abstract Experimental economics has grown as a discipline from near non‐existence 50 years ago to a full‐fledged field within economics in the present. Much of experimental economics research involves experimental methods as a tool, applied to problems in other fields of economics. However, some of this research is inward looking, focusing on questions of the methodology of experimental economics. In this note, I briefly discuss two methodological issues in experimental economics that might benefit from meta‐analysis: the pool from which experimental participants are drawn (university undergraduate students versus other populations) and the scale of monetary incentives faced by participants (large, small or hypothetical).  相似文献

In general, papers reporting the results of research studies disclose little detail regarding attributes of study design, analytical processes and methods actually used by researchers. This paper describes in some depth the method choices and analytical protocol used in a field study project. The paper describes initially the link between research question, research design and analytical protocol. The major focus of the paper is the application of a systematic analytical protocol designed to encourage completeness and impartiality in the collection and analysis of qualitative data. These method issues are examined in the context of the author's experiences in the field and through the process of data analysis. The methods used are also examined critically in retrospect.  相似文献

Analytical Procedures (APs) provide a means for auditors to evaluate the “reasonableness” of financial disclosures by comparing a client’s reported performance to expectations gained through knowledge of the client based on past experience and developments within the company and its industry. Thus, APs are fundamentally different than other audit tests in taking a broader perspective of an entity’s performance vis‐à‐vis its environment. As such, APs have been found to be a cost‐effective means to detect misstatements, and many have argued that a number of prior financial frauds would have been detected had auditors employed effective APs. With several dramatic and far‐reaching developments over the past decade, the current study examines whether and how APs have changed during this period. In particular, we focus on the impact of significant “enablers” and “drivers” of change such as technological advancements and the enactment of the Sarbanes‐Oxley Act. We also compare our findings to an influential study of the practices of APs by Hirst and Koonce (1996) that was conducted over 10 years ago. We interview 36 auditors (11 seniors, 13 managers, and 12 partners) from all of the Big 4 firms using a structured questionnaire. The data reveal some similarities in findings when compared to prior research (e.g., auditors continue to use fairly simple analytical procedures). However, there are a number of significant differences reflecting changes in AP practices. For instance, as a result of technology auditors now rely more extensively on industry and analyst data than previously. Further, auditors report that they develop more precise quantitative expectations and use more non‐financial information. They also appear to rely more on lower level audit staff to perform APs, conduct greater inquiry of non‐accounting personnel, and are willing to reduce substantive testing to a greater extent as a result of APs conducted in the planning phase. Finally, the Sarbanes‐Oxley Act has had an impact in greater consideration and knowledge of internal controls, which is seen as the most important factor driving the use and reliance on APs.  相似文献

The purpose of this paper is to identify the strengths and weaknesses of three research methods employed in managerial accounting: experimental, survey and field research. We do this by drawing on the three papers published in this issue of the Journal. These three papers provide the reader with a 'behind the scenes' exposé on the problems, choices and decisions confronted by the researcher during the method phase of the empirical study. The complexities associated with method are rarely reported in published papers nor is there any explanation of why effort is devoted to particular methodological issues. It is, however, important for the novice researcher to recognise these choices and problems, both when selecting a particular method, and in designing a study. We attempt to critique these papers in terms of choice of method and also the extent to which each of the studies satisfies the three 'maxims' of scientific method, namely, construct validity, internal validity and external validity. Our review demonstrates the trade-offs that are necessarily made when designing a research study. There are, however, ways in which the effects of these trade-offs can be minimised and we provide guidance as to how the study design might be improved to achieve this.  相似文献
