Studying the level-effect in conjoint analysis: An application of efficient experimental designs for hyper-parameter estimation

Research in marketing, and business in general, involves understanding when effect-sizes are expected to be large and when they are expected to be small. An example is the understanding of the level-effect in marketing, where the effect of product attributes on utility is positively related to the number of levels present among choice alternatives. Knowing when consumers are sensitive to the competing levels of attributes is an important aspect of merchandising, selling and promotion. In this paper, we propose a model and a method for studying the level-effect in conjoint analysis. The model combines perceptual theories in psychology to arrive at a non-linear specification of hyper-parameters in a hierarchical model. The method applies an experimental design criterion for efficient estimation of hyper-parameters. The proposed model and method are validated using a national sample of respondents.      

Sequential sampling models of choice: Some recent advances

Choice models in marketing and economics are generally derived without specifying the underlying cognitive process of decision making. This approach has been successfully used to predict choice behavior. However, it has not much to say about such aspects of decision making as deliberation, attention, conflict, and cognitive limitations and how these influence choices. In contrast, sequential sampling models developed in cognitive psychology explain observed choices based on assumptions about cognitive processes that return the observed choice as the terminal state. We illustrate three advantages of this perspective. First, making explicit assumptions about underlying cognitive processes results in measures of deliberation, attention, conflict, and cognitive limitation. Second, the mathematical representations of underlying cognitive processes imply well documented departures from Luce’s Choice Axiom such as the similarity, compromise, and attraction effects. Third, the process perspective predicts response time and thus allows for inference based on observed choices and response times. Finally, we briefly discuss the relationship between these cognitive models and rules for statistically optimal decisions in sequential designs.     

The Effects of Gender and Career Stage on Ethical Judgment

This article reports the findings of a survey examining if there are gender and career stage differences between male and female practitioners regarding ethical judgment. The results show that, on average, females adopted a more strict ethical stance than their male counterparts on 7 out of 19 vignettes. Males on the other hand, demonstrated a more ethical stance than their female counterparts on 2 out of 19 vignettes. The results furthermore indicate there is a significant difference in ethical judgment across career stages. Overall, it appears that practitioners in later career stages display higher ethical judgment than practitoners in lower career stages. Implications are provided for both practitioners and academicians.     

A Partnership Model of Corporate Ethics

The stock market crash of 1987 had a profound effect on corporate Australia and the Australian community in general. The fall-out revealed that some of our most respected business figures had not been as ethical, or even as lawful, as we would have hoped. This impropriety produced in Australia an awakening to business ethics. Whilst many companies endeavoured to introduce ethical practices into their corporations, they perceived ethics as a way of minimising damage to the corporation and in some cases as a means of competitive advantage. What was lost was the reason that one should embark on business ethics; and that is to make the society and corporate Australia a more ethical place in which to exist.This paper proposes a model based on 2 factors: commitment and partnerships, as a means of enabling corporate Australia to refocus attention on the main purpose of being inherently ethical in all that we do. This ethical model requires a commitment to partnerships with all stakeholders both internal and external in an attempt to enhance the level of ethical business practices that are contemplated and pursued within corporate Australia. Whilst the research agenda and the information collected is Australian-based, it is hoped that the ideas contained within this paper will have a wider appeal to corporations in similar cultural settings.     

Manufacturing Site Location Preferences of Small Agribusiness Firms

This study examined the perceived importance of site location characteristics identified in a 1999 survey of 198 small Tennessee agribusinesses. Responding firms ranked proximity to buyers/customers, labor, and raw materials above other factors. However, the relative importance of all factors varied by industry subsector. For example, compared to food processing firms, textile milling and lumber/wood products firms perceived community incentives as less important. Projected firm growth and current location also affected the perceived importance of site location factors. The diversity of perceived factor importance across agribusiness subsectors supports the idea that incentives and promotion of site location factors to attract small agribusiness may need to be tailored to meet specific firms' needs.     

Modeling Simultaneity in Survey Data

Responses to questions in a survey can reflect a behavior process that influences multiple response items. Respondent ratings of brand attributes, for example, can be affected by past purchases by making a brand more salient, or by respondents attributing higher performance to justify their purchases. When multiple response items are influenced by a common underlying process, there is simultaneity in the data. This paper proposes an approach to model the simultaneity in different survey responses by using common parameters and structural relationships motivated by behavioral theories on how consumers respond to surveys. Specifically, the proposed models show how brand usage and attribute perception responses are jointly determined by justification, order, and brand halo effects in two brand positioning studies. We detect a significant tendency for respondents to inflate their reported beliefs for particular brands as well as the selected brand across five countries in an international survey as well as in a domestic study.

The determinants of reserves disclosure in the extractive industries: evidence from Australian firms

This paper examines the determinants of reserves disclosure (RD) in the Australian extractive industries. Our regression results indicate that RD are positively associated with variables relating to corporate governance, foreign listing, existence of reserves in foreign jurisdictions, pledging of reserves in debt covenants, leverage and external (Big 4) auditor, after controlling for firm size, subindustry, shareholder concentration and development/production stage. Additional regression testing shows that the existence of reserves in foreign jurisdictions is the most important determinant of RD in Australia. This paper contributes to a better understanding of the extent and rationale behind the RD practices of Australian resource firms.     

PCAOB Inspections: Public Accounting Firms on “Trial”

The objective of our article is to obtain a better understanding of how auditors anticipate the potential for PCAOB inspection, experience the inspection, cope with the consequences of the inspection, and understand the PCAOB's influence within the context of professionalism. We use a qualitative approach that uses both surveys (55) and interviews (20) of auditors (of varying rank and firm) across a five‐year period (2012–2017). Respondents suggest that PCAOB inspectors are powerful, representing the “prosecution,” “judge,” and “jury” of the auditing profession. We therefore use a structural metaphor of the PCAOB inspection as a judicial “trial.” By controlling the criteria used to evaluate performance, inspectors have the power to repeatedly “subpoena,” “interrogate,” and return a “verdict” on the firm (auditor); those judged as “guilty” require supervised “probation.” This process is perceived as having improved audit quality but at a cost. Passing an inspection is so important that auditors (firms) have resorted to impression management strategies and “functionally stupid” work practices (e.g., excessive documentation, a decrease in critical thinking as a result of a “box ticking” approach to auditing). Furthermore, some respondents believe that being a good auditor has come at the expense of being a good accountant; the emphasis on audit process and concurrent de‐emphasis on technical accounting could ultimately lead to audits themselves falling short. In addition, it is evident that inspectors and auditors differ in their perceptions of risk, likely manifesting because inspectors are standards‐focused while auditors (firms) are methodology‐focused. Finally, the inspection process has created excessive stress and tension, beyond budget and fee pressures, which some auditors perceive as affecting the pool of talented auditors that firms may be able to attract and retain in the future.
