Research article: Look after they leap: illustrating the value of retrospective reports in employee turnover

The prevailing methodology for studying employee turnover is limited because it emphasizes prediction rather than understanding. This paper critiques this methodology and draws out the implications of an alternative: retrospective self-reporting, by actual leavers. Retrospective self-reporting has three main advantages. First, it allows direct assessment of actual incidents of turnover, so interventions can be informed by accounts of real events, instead of being based on inference. Second, it offers insight into the dynamic character of decisions to quit, which are often unpredictable or precipitated by sudden events. Third, it allows for assessment of the role of non-work factors. This makes a methodological contribution, allowing greater insight into the decision to quit, which is ontologically, socially and dynamically complex. It has implications for how we construe and manage turnover. The argument is illustrated by a recent study of 352 UK National Health Service nurse leavers but has wider implications for turnover in the public sector.     

Health Care Matters: Supply Chains In and Of the Health Sector

Providing health care involves a complex enterprise, and the trade‐off between quality and cost has been particularly stark compared to other industries. However, a recent focus on health sector supply networks is now producing significant innovations and improvements. This Special Topic Forum illustrates for the academic and practitioner community how health care supply chain research can benefit from our evolving understanding of supply chains and help push that understanding even further. We classify health care supply chain research into two broad categories—supply chain in health care and supply chain of health care—to set an agenda for future research.     

A Note on the Interdependence between Hypothesis Generation and Information Search in Conducting Analytical Procedures*

This study examines the linkage among the initial hypothesis set, the information search, and decision performance in performing analytical procedures. We manipulated the quality of the initial hypothesis set and the quality of the information search to investigate the extent to which deficiencies (or benefits) in either process can be remedied (or negated) by the other phase. The hypothesis set manipulation entailed inheriting a correct hypothesis set, inheriting an incorrect hypothesis set, or generating a hypothesis set. The information search was manipulated by providing a balanced evidence set to auditors (i.e., evidence on a range of likely causes including the actual cause ‐ analogous to a standard audit program) or asking them to conduct their own search. One hundred and two auditors participated in the study. The results show that auditors who inherit a correct hypothesis set and receive balanced evidence performed better than those who inherit a correct hypothesis set and did their own search, as well as those who inherited an incorrect hypothesis set and were provided a balanced evidence set. The former performance difference arose because auditors who conducted their own search were found to do repeated testing of non‐errors and truncated their search. This suggests that having a correct hypothesis set does not ensure that a balanced testing strategy is employed, which, in turn, diminishes part of the presumed benefits of a correct hypothesis set. The latter performance difference was attributable to auditors' failure to generate new hypotheses when they received evidence about a hypothesis that was not in the current hypothesis set. This demonstrates that balanced evidence does not fully compensate for having an initial incorrect hypothesis set. These findings suggest the need for firm training and/or decision aids to facilitate both a balanced information search and an iterative hypothesis generation process.     

Approximately optimum two-stage sampling plans

Summary In order to compare two-stage sampling plans we use the minimax regret principle i.e. the minimax principle applied to the corresponding regret functions. In this paper approximation formulas for optimum two-stage sampling plans are derived in the case of sampling by attributes as well as in the case of sampling by variables; furthermore a method is presented how to improve the approximate solution in the first case.     

A generalized multi-country endogenous growth model

The transitional dynamics of open-economy endogenous growth models are largely unexplored. The present paper fills this gap in the literature. By applying the familiar Travis–Dixit–Norman (Dixit and Norman, Theory of International Trade, Cambridge University Press, Cambridge, UK, 1980) approach to a general class of growth models, it provides original results on the transitional dynamics of the multi-country open-economy versions of several prominent special cases, including the models of Romer (J Polit Econ, 94:1002–1037, 1986; J Polit Econ 98:S71–S102, 1990), Lucas (J Monet Econ, 22:3–42, 1988), Grossman and Helpman (Innovation and Growth in the Global Economy. MIT Press, Cambridge, MA, 1991a, Chaps. 3 and 4; Rev Econ Stud 58:43–61, 1991b), Jones (J Polit Econ, 103:759–784, 1995a), and Segerstrom (Am Econ Rev, 88:1290–1310, 1998). This approach also shows that, in the class of models considered, the question of whether or not international economic integration accelerates growth in the long run is equivalent to the question of whether or not scale effects prevail.      

Financial Evaluation of the Product Line

When decisions are being made about adding or dropping a product, most managers will make a financial evaluation of the product and they may try to get some sense of the riskiness of the decision. They will also probably consider the effect of the add/drop decision on other products in the line. Seldom, however, do they consider the risk of a product mix decision in the context of the risk level of the overall product line. Professors Rabino and Wright argue that product managers should take a leaf from the analytical book of financial analysts and calculate a "product Beta" that shows the impact of the risk of the individual product on the risk of the whole portfolio of products. They also suggest some other ways of sharpening the financial picture in what are often strictly marketing evaluations. This is Professor Rabino's second article in JPIM . As in the previous one he coauthored with Howard Moskowitz, this one adds some interesting analytical methodology to managerial decision making.     

The Principal-Agent Relationship in Real Estate Brokerage Services

This article investigates the principal-agent relationship between the owner of a house and her real estate broker. The principal's (owner's) problem is to design a contract that induces the agent (broker) to adopt a selling strategy that maximizes the owner's expected return. A sequential search model is utilized to analyze this principal-agent relationship. Three different systems for paying the broker are considered: fixed-percentage commission, flat-fee, and consignment. Both the discount factors of the owner and the broker and the net costs of ownership incurred while attempting to sell the house play a central role in determining the nature of the optimal contract. The analysis demonstrates that the fixed-percentage commission system is the only one of the three systems considered that can induce a first-best, incentive-compatible contract. A numerical analysis provides insights regarding the effect of the fixed-percentage commission system on competition in the real estate brokerage industry.     

Focus group methods: Using interactive and nominal groups to explore emerging technology-driven phenomena in accounting and information systems

This paper puts forth arguments for why focus group methods should be used more frequently in accounting and information technology research in order to address emerging technology-driven phenomena in accounting. In this overview of focus group methods and their application to studying accounting and information technology phenomena, we focus on what alternative types of focus group methods may be applied, when such methods are applicable, and what methodological challenges the researcher must address. In examining the methodological challenges that face researchers when using these methods, we demonstrate how these challenges have been addressed in our own research as a way of exemplifying the challenges researchers may face and what compensating strategies researchers might use. Our objective is to highlight when focus groups may be the best method for accounting information systems researchers and demonstrate how they can be used when they are applicable.
