Purpose – The purpose of this study is to present a report on the development of an improved mathematical model for quantifying the cost of quality. In addition, a simulation model is developed using real-life industrial data; the model is used to investigate the impact of certain quality control level plans on cost of quality. Design/methodology/approach – The cost of the quality model was developed based on the reported literature and suggestion from the company quality control manager. An extensive discussion was conducted with the quality control supervisors in the company to develop some quality control plans to investigate their impact on cost of quality. A simulation model that represents a specific section of the process at the company was used to carry out the investigation. The results were analysed and compared with some important findings reported in the literature that describe the characteristics of costs of quality. Findings – The simulation work provides valuable insights into the behavior of the different components that constitute the total cost of quality. The results show that reduction of failure costs can be achieved at low or no-subsequent increase in the non-conformance expenditure. In addition, it seems that the traditional accounting system approach may no longer be adequate since it depends mainly on direct labour costs. The results indicate that the direct labour cost is only contributing by about 3 percent of the total cost of quality. Research limitations/implications – This paper focuses on the development of a comprehensive model for quantifying the cost of quality in a semiconductor company. Future research is needed to expand the model for more complex process configuration. In addition, the developed model could be extended to deal with variant defect rates. Originality/value – This study presents an advanced theoretical model for cost quality that enhanced models of quality presented in the literature. Using the developed cost of the quality model, a comprehensive simulation was carried out to investigate the impact of some quality plans on cost of quality. The study clearly indicates important evidence to justify the implementation of cost of quality models in real-life industry.

Purpose The purpose of this paper is to provide empirical evidence for competing representations of the prevention-appraisal-failure model of quality cost. Design/methodology/approach The authors conduct regression analysis on a secondary data set to reveal relationships among total cost of quality, its components and overall quality performance. Findings Total cost of quality and its failure cost component are significantly lower at higher levels of quality, while the prevention and appraisal cost components are not observed to be significantly higher at higher levels of quality. The authors propose a modification to the modern representation of the prevention-appraisal-failure model. Practical implications In manufacturing, ever higher levels of quality are associated with significantly lower quality cost. Originality/value Using a large, unique data set for secondary analysis, combined with employing a high-level measure for overall quality performance, the authors provide evidence for the aggregate explanatory power of prevalent representations of the prevention-appraisal-failure cost of quality model.

The Impact

Purpose – The purpose of this paper is to explore the impact of creditors' undervaluing the total expected cost of a borrower's bankruptcy filing because a portion of the cost will be borne by other lenders. Creditors who bear a smaller portion of the total cost of a personal bankruptcy would be expected to take less care to avoid triggering one. Design/methodology/approach – This paper presents a theoretical model of a creditor's decision of how aggressively to pursue collection. The model shows that because each lender's collection actions increase the probability of bankruptcy, each lender will collect more aggressively when a borrower has many loans. The paper tests the predictions of the model using a large dataset of credit card accounts. Findings – The model highlights an important testable result: holding the level of debt constant, a borrower with many loans is more likely to choose formal bankruptcy and less likely to choose informal bankruptcy, i.e. chronic non-repayment absent a bankruptcy filing. This paper finds evidence that strongly supports the predictions of the model. Laws that limit creditor collection actions do not appear to mitigate the effects of increasing number of loans. Originality/value – While a few papers have tested whether strategic interactions may impact business bankruptcy, no paper of which the author is aware has provided clear empirical evidence of the existence of common pool effects in the personal credit market. These effects point to an important and potentially underappreciated source of risk for borrowers and creditors in this market.

SummaryPatient access to care and long wait times has been identified as major problems in outpatient delivery systems. These aspects impact medical staff productivity, service quality, clinic efficiency, and health-care cost.This study proposed to redesign existing patient types into scheduling groups so that the total cost of clinic flow and scheduling flexibility was minimized. The optimal scheduling group aimed to improve clinic efficiency and accessibility.The proposed approach used the simulation optimization technique and was demonstrated in a Primary Care physician clinic. Patient type included, emergency/urgent care (ER/UC), follow-up (FU), new patient (NP), office visit (OV), physical exam (PE), and well child care (WCC). One scheduling group was designed for this physician. The approach steps were to collect physician treatment time data for each patient type, form the possible scheduling groups, simulate daily clinic flow and patient appointment requests, calculate costs of clinic flow as well as appointment flexibility, and find the scheduling group that minimized the total cost.The cost of clinic flow was minimized at the scheduling group of four, an 8.3% reduction from the group of one. The four groups were: 1. WCC, 2. OV, 3. FU and ER/UC, and 4. PE and NP. The cost of flexibility was always minimized at the group of one. The total cost was minimized at the group of two. WCC was considered separate and the others were grouped together. The total cost reduction was 1.3% from the group of one.This study provided an alternative method of redesigning patient scheduling groups to address the impact on both clinic flow and appointment accessibility. Balance between them ensured the feasibility to the recognized issues of patient service and access to care. The robustness of the proposed method on the changes of clinic conditions was also discussed.

Purpose The purpose of this paper is to examine the impact of labor market freedom on state-level cost of living differentials in the USA using cross-sectional data for 2016 after allowing for the impacts of economic and quality of life factors. Design/methodology/approach The study uses two-stage least squares estimation controlling for factors contributing to cost of living differences across states. Findings The results reveal that an increase in labor market freedom reduces the overall cost of living. Research limitations/implications The study can be extended using panel data and alternative measures of labor market freedom. Practical implications In general, the finding that less intrusive government and greater labor freedom are associated with a reduced cost of living should not be surprising. This is because less government intrusion and greater labor freedom both inherently allow markets to be more efficient in the rationalization of and interplay with forces of supply and demand. Social implications The findings of this and future related studies could prove very useful to policy makers and entrepreneurs, as well as small business owners and public corporations of all sizes – particularly those considering either location in, relocation to, or expansion into other markets within the USA. Furthermore, the potential benefits of the National Right-to-Work Law currently under consideration in Congress could add cost of living reductions to the debate. Originality/value The authors extend the literature on cost of living differentials by investigating whether higher amounts of state-level labor market freedom act to reduce the states’ cost of living using the most recent annual data available (2016). That labor freedom has a systemic efficiency impact on the state-level cost of living is a significant finding. In our opinion, it is likely that labor market freedom is increasing the efficiency of labor market transactions in the production and distribution of goods and services, and acts to reduce the cost of living in states. In addition, unlike previous related studies, the authors investigate the impact of not only overall labor market freedom on the state-level cost of living, but also how the three sub-indices of labor market freedom, as identified and measured by Stansel et al. (2014, 2015), impact the cost of living state by state.

Tax Accounting

Subject. This article explores the origination of the differences between bookkeeping and tax accounting, and their impact on decision-making. Objectives. The article aims to examine the reasons for the discrepancies between bookkeeping and tax accounting, reveal some aspects of accounting of differences from the position of their registration in a uniform accounting system or two parallel systems, if available, and determine the impact of such gaps on investment and management decisions. Methods. For the study, we used analysis and synthesis, observation, comparison, and the dialectical and data collection methods. Results. The article reveals the key features of the interaction between bookkeeping and tax accounting in Russia and foreign countries. It justifies that in today's economic realities, addressing shortcomings between these information systems is not a necessity, and shows the possible impact of differences on investment decisions. The article also graphically presents the application of cost-plus and balance-based methods of accounting for deferred taxes depending on the way information systems are organized, as well as their comparative characteristics. Conclusions and Relevance. The discrepancies between the two accounting systems provide an opportunity to assess the impact of tax planning on drawing a veil over the accounting profit. Studying the cost and balance methods, as well as the dialectic of the interaction of tax planning with the accounting information system, remain relevant. The results of the study can be useful to accounting and tax specialists, and other stakeholders who are studying the interactions of these information systems.

The Cost

Purpose Positive behavioural support has been considered as a valuable alternative to residential care for children and adolescents with learning disabilities and behaviour that challenges. While recent evidence suggests it has a positive impact on behaviour and carer ability to cope, there is little evidence of its economic costs or benefits. The paper aims to discuss this issue. Design/methodology/approach An exploratory cross-sectional study was conducted to evaluate the cost of providing positive behavioural support to ten children and adolescents with learning disabilities and behaviour that challenges living in the community in Ealing, West London. Comparison was also made with the cost estimate of possible alternative support packages for children and adolescents with learning disabilities and behaviour that challenges in the UK, as obtained through a Delphi exercise. Findings Total cost of services per child was £1,454 per week for young people supported short-term, and £1,402 supported long-term. Children and adolescents were making use of a range of social care, education and health services. Over the full sample, half of the total cost was accounted for by education services. The Delphi exercise estimated the weekly cost of residential-based care as more expensive than the cost of community-based care for children and adolescents with learning disabilities and behaviour that challenges. At the end of the ITSBS, all ten children and adolescents initially at risk of imminent residential placement were living in the community with less service-intensive and less expensive support. This suggests that avoiding residential-based care could reduce costs in the long term. Originality/value Positive behavioural support has potential to support people with learning disabilities and behaviour that challenges in the community, leading to potential cost advantages. However, this is a small study and more robust research is needed.

Starting A Business

Purpose The purpose of this paper is to examine the effects of culture, legal origin and religion on four measures of the ease of starting a new business; the number of procedures required, the number days required, the ease of getting credit and the cost to start a business. Design/methodology/approach The authors use linear regression to test the hypotheses using publicly available data on legal origin and religion from La Porta et al. (1999), cultural dimension information from Hofstede (2009) and measures of the ease of starting a business from the World Bank’s (2017) Doing Business Initiative. The final sample consists of 71 countries for which information was available on all the variables of interest. Findings Legal origin affects the number of procedures and the length of time needed to start a business, as well as the ease of getting credit. Culture (power distance) and religion are important for explaining gender differences in the ease of starting a business. The cost of starting a business is unrelated to culture, legal origin or religion. Originality/value Economic development is an important determinant of a country’s political stability and standard of living. Although politicians play a significant role in how a friendly a country is toward business, the study demonstrates that other longer-term and less dynamic factors have a material influence on economic development.

The Impact

Purpose Earnings quality is of great concern to corporate stakeholders, including capital providers in international markets with widely varying regulatory pedigrees and ownership patterns. This paper aims to examine the association between the cost of equity capital and earnings quality, contextualised via tests that incorporate the potential for moderating effects around institutional settings. The analysis focuses on and compares evidence relating to (common law) UK/US firms and (civil law) German firms over the period 2005–2018 and seeks to identify whether, given institutional dissimilarities, significant differences exist between the two settings. Design/methodology/approach First, the authors undertake a review of the extant literature on the link between earnings quality and the cost of capital. Second, using a sample of 948 listed companies from the USA, the UK and Germany over the period 2005 to 2018, the authors estimate four implied cost of equity capital proxies. The relationship between companies’ cost of equity capital and their earnings quality is then investigated. Findings Consistent with theoretical reasoning and prior empirical analyses, the authors find a statistically negative association between earnings quality, evidenced by information relating to accruals and the cost of equity capital. However, when they extend the analysis by investigating the combined effect of institutional ownership and earnings quality on financing cost, the impact – while negative overall – is found to vary across legal backdrops. Research limitations/implications This paper uses institutional ownership as a mediating variable in the association between earnings quality and the cost of equity capital, but this is not intended to suggest that other measures may be of relevance here and additional research might usefully expand the analysis to incorporate other forms of ownership including state and foreign bases. Second, and suggestive of another avenue for developing the work presented in the study, the authors have used accrual measures of earnings quality. Practical implications The results are shown to provide potentially important insights for policymakers, creditors and investors about the consequences of earnings quality variability. The results should be of interest to firms seeking to reduce their financing costs and retain financial viability in the wake of the impact of the Covid-19 pandemic. Originality/value The reported findings extends the single-country results of Eliwa et al. (2016) for the UK firms and Francis et al. (2005) for the USA, whereby both reported that the cost of equity capital is negatively associated with earnings quality attributes. Second, in a further increment to the extant literature (particularly Francis et al., 2005 and Eliwa et al., 2016), the authors find the effect of institutional ownership to be influential, with a significantly positive impact on the association between earnings quality and the cost of equity capital, suggesting in turn that institutional ownership can improve firms’ ability to secure cheaper funding by virtue of robust monitoring. While this result holds for the whole sample (the USA, the UK and Germany), country-level analysis shows that the result holds only for the common law countries (the UK and the USA) and not for Germany, consistent with the notion that extant legal systems are a determining factor in this context. This novel finding points to a role for institutional investors in watching and improving the quality of financial reports that are valued by the market in its price formation activity.

Purpose – Ensuring the sufficient service level is essential for critical materials in industrial maintenance. This study aims to evaluate the use of statistically imperfect data in a stochastic simulation-based inventory optimization where items' failure characteristics are derived from historical consumption data, which represents a real-life situation in the implementation of such an optimization model. Design/methodology/approach – The risks of undesired shortages were evaluated through a service-level sensitivity analysis. The service levels were simulated within the error of margin of the key input variables by using StockOptim optimization software and real data from a Finnish steel mill. A random sample of 100 inventory items was selected. Findings – Service-level sensitivity is item specific, but, for many items, statistical imprecision in the input data causes significant uncertainty in the service level. On the other hand, some items seem to be more resistant to variations in the input data than others. Research limitations/implications – The case approach, with one simulation model, limits the generalization of the results. The possibility that the simulation model is not totally realistic exists, due to the model's normality assumptions. Practical implications – Margin of error in input data estimation causes a significant risk of not achieving the required service level. It is proposed that managers work to improve the preciseness of the data, while the sensitivity analysis against statistical uncertainty, and a correction mechanism if necessary, should be integrated into optimization models. Originality/value – The output limitations in the optimization, i.e. service level, are typically stated precisely, but the capabilities of the input data have not been addressed adequately. This study provides valuable insights into ensuring the availability of critical materials.

Purpose The purpose of this paper is to report on the impact of the internship experience on business students’ career intentions in regard to pursuing a career path in the same job function or industry as their internship. Design/methodology/approach After completing and reflecting on an internship, 198 undergraduate students responded to the prompt: “discuss the impact of the internship on your career consideration.” Responses were analyzed using a content analysis methodology in order to determine whether or not interns would pursue the same job functions (e.g. sales) or industry (e.g. non-profit) as their internship in their post-graduation job search. Findings Across the job functions and industries identified within the internships, 54 and 45 percent of interns confirmed their expectations of career fit, respectively. The implications of confirming and disconfirming these expectations for students are discussed. Originality/value Given the value of internships to business students, surprisingly few studies have examined their influence on undergraduates’ career considerations. Students select internships with the intention of learning about job functions or industries for possible career fit, yet the authors know little about whether the experience confirms or disconfirms their expectations. This study seeks to address this gap. The authors suggest that internships, as experiential activities, merit greater attention as they provide students opportunities to learn what they do or do not want to do, where they do or do not want to work and whether their self-concept fits a possible career path – saving themselves and potential employers the cost of job dissatisfaction and turnover.
