Management situations and the engineering mindset

This paper uses the method of assumptional analysis to understand the behavior patterns and the problem-solving strategies employed by the engineer/scientist. It is shown that the engineering mindset, although useful for the solution of the problem situations that generally arise in the engineering fields, has serious inadequacies, and is often counterproductive, in handling ill-structured management problems; hence, the often reported, less-than-adequate performance of engineers in management situations. This article moves from the analysis of engineering-problem situations to the basic assumptions underlying the engineer's world picture and thence to the engineer's strategies for problem solution. Comparisons with the nature of management situations, the manager's world picture, and his problem-handling activities are made. The analysis is, in the main part, paradigmatic. It is pointed out that the basic feature of all ill-structured problems is that they network across many and diverse knowledge bases. Further, this article argues that a new and different world view needs to be introduced into the training of future generations of engineers, for with the increased networking of society, not just management but also technological problem situations will move more and more towards the ill-structured end of the spectrum.     

Spurious Regressions in Financial Economics?

Even though stock returns are not highly autocorrelated, there is a spurious regression bias in predictive regressions for stock returns related to the classic studies of Yule (1926) and Granger and Newbold (1974) . Data mining for predictor variables interacts with spurious regression bias. The two effects reinforce each other, because more highly persistent series are more likely to be found significant in the search for predictor variables. Our simulations suggest that many of the regressions in the literature, based on individual predictor variables, may be spurious.     

Reflections on discriminant validity: Reexamining the Bove et al. (2009) findings

Bove, Pervan, Beatty and Shiu (2009) develop and test a latent variable model of the role of service workers in encouraging helpful behaviors by customers towards the service business (OCBs). Farrell (2010) questions these findings due to an incorrect application of the Fornell and Larcker (1981) discriminant validity test. The authors respond to Farrell's criticism by discussing the options available for assessing discriminant validity, the current use of these options in top journals, the underlying assumptions of these assessments, and the appropriateness of the alternative assessments under different types of situations. Finally, the authors address the specific concerns raised in Farrell (2010) in regard to Bove et al. (2009).     

Understanding Audit Quality: Insights from Audit Professionals and Investors

Projects seeking to define, measure, and evaluate audit quality are on the agendas of auditing standards setters as well as audit firms. The Public Company Accounting Oversight Board (PCAOB) currently provides information regarding audit quality through the release of inspection reports, and the Board intends to establish and report audit quality indicators. To provide additional perspective on audit quality, we obtain auditors' and investors' views, definitions, and indicators of audit quality. We find that investors' definitions of audit quality focus more on inputs to the audit process than do auditors', and that investors view the number of PCAOB deficiencies as an indicator of overall firm quality. We find a consensus that auditor characteristics may be the most important determinants of audit quality, and that restatements may be the most readily available signal of low audit quality. We relate responses to a general audit quality framework, provide support for archival audit research, and identify additional disclosures that participants suggest could signal audit quality. Taken together, we provide evidence regarding the construct of audit quality in the post‐SOX environment, evaluate many of the audit quality indicators proposed by the PCAOB, and suggest avenues for future research.     

Access (Not) Denied: The Impact of Financial, Human, and Cultural Capital on Entrepreneurial Entryin the United States

Entrepreneurship contributes to business dynamics in all economies, and the individual benefits of starting a business are clear. Nonetheless, access to business start-ups may not be available to all people because of resource constraints. Using a unique new data set for the United States, we examine the relative importance of three forms of resources in pursuing start-up ventures: financial, human, and cultural capital. Our analysis of the Panel Study of Entrepreneurial Dynamics shows that neither financial nor cultural capital resources are necessary conditions for entrepreneurial entry. By contrast, potential entrepreneurs gain significant advantages if they possess high levels of human capital. Specifically, advanced education and managerial experience are significantly positively associated with entrepreneurial entry. Our findings suggest that attempts at entering entrepreneurship, at least in the short-term, may be increasing, as opportunities to acquire human capital are becoming more widespread.

Job Satisfaction in Britain

Little recent empirical work in economics or industrial relations has examined job satisfaction, despite its demonstrated correlation with labour market behaviour such as quits, absenteeism and productivity. This paper uses information from a study of 5000 British employees to investigate the relationship between three measures of job satisfaction and a wide range of individual and job characteristics. Notably, men, workers in their thirties, the well-educated, those working longer hours and workers in larger establishments have lower levels of job satisfaction. The estimated job satisfaction equations are used to calculate a measure of the shadow wage and to provide some evidence that is consistent with the existence of non-compensating differentials in the industry and occupational wage structure.
