Experimental comparison of Web, electronic and mail survey technologies in operations management

With the growing acceptance of the Web (Internet) and electronic mail, it is no surprise that researchers are using an increasingly diverse set of survey technologies to gather data from managers. However, the effectiveness of these electronic technologies has not been rigorously assessed, especially for gathering data from establishment-level surveys (i.e. firm- or plant-level). To that end, a stratified sample of large and small, service and manufacturing firms was constructed, followed by random assignment to one of four survey technologies: mail, fax, PC disk-by-mail and Web-page survey (combined with e-mail notification). For each treatment, managers are queried about their use of forecasting characteristics, yielding a sample of 118 firms. Unfortunately, only a low percentage (34%) of firms and managers assigned to the Web technology treatment both reported access to e-mail and were willing provide their e-mail addresses; they tended to be large firms and from the service sector. Moreover, those that did offer e-mail addresses were only about half as likely to respond to the Web-based survey as those targeted by other survey technologies. However, Web, fax and disk-by-mail technologies yielded higher item completion rates than mail. Limited statistical evidence indicated that respondents using computer-based survey technologies (i.e. Web or disk-by-mail) generally reported forecasting characteristics that are associated with firms exhibiting best practices. Thus, a multi-technology survey approach using the Web and fax can yield a strong combination of benefits over a traditional mail survey.     

Sex and salary: A survey of purchasing and supply professionals

The purpose of this paper is to test a series of hypotheses, derived from compensation theory, on predictors of purchasing and supply management salaries. One of the hypotheses, on the effect of sex on salary, assesses competing theories, i.e. human capital versus discrimination. These hypotheses are tested using the results of a survey on purchasing and supply management salaries in Canada. Six variables were found to be significant predictors of salary. Purchasers with a professional designation, more education, more experience, greater spend responsibility, at larger organizations, and with greater share of compensation coming as a bonus reported larger salaries. In addition, after controlling for these human capital and organizational context variables, sex had a significant impact on salary. Male purchasing and supply managers reported earning significantly higher salaries than their female counterparts. The paper concludes with implications for purchasing employees and employers, along with discussion of future research opportunities.     

M5 accuracy competition: Results,findings, and conclusions

In this study, we present the results of the M5 “Accuracy” competition, which was the first of two parallel challenges in the latest M competition with the aim of advancing the theory and practice of forecasting. The main objective in the M5 “Accuracy” competition was to accurately predict 42,840 time series representing the hierarchical unit sales for the largest retail company in the world by revenue, Walmart. The competition required the submission of 30,490 point forecasts for the lowest cross-sectional aggregation level of the data, which could then be summed up accordingly to estimate forecasts for the remaining upward levels. We provide details of the implementation of the M5 “Accuracy” challenge, as well as the results and best performing methods, and summarize the major findings and conclusions. Finally, we discuss the implications of these findings and suggest directions for future research.     

QUALITATIVE AND MIXED‐METHODS RESEARCH IN ECONOMICS: SURPRISING GROWTH,PROMISING FUTURE

Qualitative research in economics has traditionally been unimportant compared to quantitative work. Yet there has been a small explosion in use of quantitative approaches in the past 10–15 years, including ‘mixed‐methods’ projects which use qualitative and quantitative methods in combination. This paper surveys the growing use of qualitative methods in economics and closely related fields, aiming to provide economists with a useful roadmap through major sets of qualitative methods and how and why they are used. We review the growing body of economic research using qualitative approaches, emphasizing the gains from using qualitative‐ or mixed‐methods over traditional ‘closed‐ended’ approaches. It is argued that, although qualitative methods are often portrayed as less reliable, less accurate, less powerful and/or less credible than quantitative methods, in fact, the two sets of methods have their own strengths, and how much can be learned from one type of method or the other depends on specific issues that arise in studying the topic of interest. The central message of the paper is that well‐done qualitative work can provide scientifically valuable and intellectually helpful ways of adding to the stock of economic knowledge, especially when applied to research questions for which they are well suited.     

Influence diagnostic in survey sampling: Estimating the conditional bias

The conditional bias has been proposed by Moreno Rebollo et al. (1999) as an influence diagnostic in survey sampling, when the inference is based on the randomization distribution generated by a random sampling. The conditional bias is a population parameter. So, from an applied point of view, it must be estimated. In this paper, we propose an estimator of the conditional bias and we study conditions that guarantee its unbiasedness. The results are applied in a Simple Random Sampling and in a Proportional Probability Aggregated Size Sampling, when the ratio estimator is used. Received October 2000     

The predictive accuracy of credit ratings: Measurement and statistical inference

Credit ratings are ordinal predictions of the default risk of an obligor. The most commonly used measure for evaluating their predictive accuracy is the Accuracy Ratio, or equivalently, the area under the ROC curve. The disadvantages of these measures are that they treat default as a binary variable, thus neglecting the timing of default events, and they fail to use all of the information available from censored observations. We present an alternative measure which is related to the Accuracy Ratio but does not suffer from these drawbacks. As a second contribution, we study statistical inference for the Accuracy Ratio and the proposed measure in the case of multiple cohorts of obligors with overlapping lifetimes. We derive methods which use more sample information and lead to tests which are more powerful than alternatives which filter just the independent part of the dataset. All procedures are illustrated in the empirical section using a dataset of S&P Credit Ratings.     

Offshoring versus backshoring: Empirically derived bundles of relocation drivers,and their relationship with benefits

This paper describes an empirically derived classification of the various factors that influence offshoring and backshoring decisions based on data from 275 offshoring and 160 backshoring projects. The study developed one set of factor bundles for offshoring and another set of such bundles for backshoring; these sets were then compared, and their relationships with post-relocation benefits were analyzed. These benefits were also grouped into bundles based on the empirical relationships. This research contributes an empirically derived classification scheme of decision factors for both offshoring and backshoring as well as an analysis of the relationships between decision factors and benefits for each type of relocation direction.     

Benchmarks and Citizen Judgments of Local Government Performance: Findings from a survey experiment

Government agencies can provide various benchmarks when reporting their performance to citizens, but not much is known about how citizens understand and respond to benchmarking information. Thus, this study aims to test what performance benchmarks appear most salient and persuasive to citizens. We conducted an online survey experiment in which n = 595 respondents were randomized to different benchmarking information concerning fourth-grade reading proficiency of an elementary school. Our findings suggest that better school performance relative to the overall state average influenced respondents’ ratings more than did performance relative to last year or similar schools. Improvement over last year, moreover, appears to be the least influential benchmark. The implication is that citizens find broad, comparative benchmarks to be the most persuasive and view reflexive benchmarks as less impressive, although confirmation of this conclusion is needed because of limitations in the design of the experiment.     

Reporting on sustainability and HRM: a comparative study of sustainability reporting practices by the world's largest companies

As a response to the growing public awareness on the importance of organisational contributions to sustainable development, there is an increased incentive for corporations to report on their sustainability activities. In parallel with this has been the development of ‘Sustainable HRM’ which embraces a growing body of practitioner and academic literature connecting the notions of corporate sustainability to HRM. The aim of this article is to analyse corporate sustainability reporting amongst the world's largest companies and to assess the HRM aspects of sustainability within these reports in comparison to environmental aspects of sustainable management and whether organisational attributes – principally country-of-origin – influences the reporting of such practices. A focus in this article is the extent to which the reporting of various aspects of sustainability may reflect dominant models of corporate governance in the country in which a company is headquartered. The findings suggest, first and against expectations, that the overall disclosure on HRM-related performance is not lower than that on environmental performance. Second, companies report more on their internal workforce compared to their external workforce. Finally, international differences, in particular those between companies headquartered in liberal market economies and coordinated market economies, are not as apparent as expected.

Vague lies and lax standards of proof: On the law and economics of advice

This paper analyzes a persuasion game where a seller provides (un)biased and (im)precise advice and may be fined by an authority for misleading the buyers. In the equilibrium, biasing the advice and making it noisier are complements. The advice becomes both more biased and less precise with a stricter standard of proof employed by the authority, a larger share of credulous consumers, and a higher buyers' heterogeneity. The optimal policy of the authority is characterized in terms of a standard of proof and resources devoted to the investigation.     

Sustainable development disclosure: Environmental,social, and governance reporting and gender diversity in the audit committee

This paper analyzes the link between female representation on audit committees (ACs) and specific information attributes of environmental, social, and governance (ESG) disclosures. We also examine whether the role of women is moderated by the busyness and intensity of the committee. Our results reveal a positive association between gender diversity in the AC and the quality of voluntary ESG reporting, which results in greater comprehensiveness and relevance. These findings extend the academic debate concerning the role of female directors on sustainability policies. Moreover, given the importance of ESG information in capital markets and its potential benefits for firms, this evidence may help regulators and owners to implement adequate corporate governance mechanisms. In addition, the busyness of the AC negatively moderates the influence of female AC members. Therefore, we highlight the need to consider the context in which women work in order to understand their influence on sustainability reporting.     

Environmental disclosures and compulsory accounting standards: the case of spanish annual reports

This paper analyses environmental reporting practices found in the annual reports published by 51 large companies operating in Spain, with the aim of determining which factors in the firms analysed – belonging to ecologically sensitive sectors – explain the quantity and characteristics of the environmental information published and its evolution. Moreover, the paper takes into account the implementation of the Spanish compulsory accounting standard of 25 March 2002 and its impact on the environmental reporting behaviour. The results of the content analysis for the period 2001–02 show a significant increase in the environmental information compared with the 1992–94 period. For the first year in which the environmental accounting standard was in force (2002), the results show a high percentage of environmental disclosures in the notes to the annual accounts, although the degree and level of disclosures is very heterogeneous, in both form as well as quantity and quality.

The how and why of integrated reporting in a public health care organization: The stakeholders' perspective

Despite the widespread calls for in‐depth case studies on adoption of the International Integrated Reporting Council Framework, in practice, it appears to be underexplored, above all in the public sector. Our aim is to explore how and why a public health care organization (PHO) has chosen to adopt the practice of integrated reporting, and we then delve into whether the PHO's perception of the document's value coincides with that of the stakeholders, who are its recipients. Often, society's perception of value can differ considerably from an organization's. Thus, for our research purposes, a case study was examined, adopting a qualitative approach and action research methodology. Our findings demonstrate the centrality of the value created for patients and of the “normative” scenario that takes place during the implementation of an integrated report in a PHO. Moreover, the concept of legitimacy was found to be virtually synonymous with institutionalization.     

Differences in work goals among regions of the Netherlands and Germany: functional,institutional and critical event influences

We use World Values Survey data from the Netherlands and Germany to compare the importance of within-nation region differences with nation differences in work goals. These two nations have historical relationships and internal differences that are especially useful for testing hypotheses about nation compared to within-nation region differences. We develop hypotheses about the implications of religious heritage and urbanization for work goals based on functional, institutional and critical event explanations for regional culture differences. A number of work goals (notably extrinsic goals like pay) show too little difference between either nations or within-nation regions to consider them. For those work goals that do show region differences, the largest differences, those for job security goals and goals for working with pleasant people, are associated with region differences between rather than within the two nations. Regional differences in some work goals are also related to religious heritage. Regional differences in work goals have implications for the kinds of HR programs that managers may wish to promote in different locations. For example, the results suggest that HR managers have reason to anticipate that policies promoting job security may receive especially positive responses in Germany, whereas programs promoting social relationships may be best received in the Netherlands. Similarly, organizations that operate in both the north and south of each country should be alert to a number of possible within-nation differences in local optimal HR policies, but the within-nation differences found here are small enough that they should be carefully checked in specific organizations.     

Corporate Governance,Integrated Reporting and the Use of Credibility-enhancing Mechanisms on Integrated Reports

The International Integrated Reporting Council (IIRC) and the South African King III Report on Governance emphasize the role of corporate governance in preparing a high-quality integrated report and establishing an appropriate credibility-enhancing process. This paper examines the significance of corporate governance mechanisms in explaining variations in the quality of integrated reports and the extent and quality of credibility-enhancing mechanisms (CEMs) for integrated reports. Using a sample of integrated reports published between 2012 and 2015 by listed companies on the Johannesburg Stock Exchange, this study finds that traditional governance mechanisms such as the board and the audit committee are positively related to the reporting quality of <IR> and use of CEMs. In addition, sustainability-oriented corporate governance mechanisms (i.e. sustainability committee and the use of non-financial performance measures in executives’ compensation contracts) have an incremental positive effect on both the quality of <IR> and the extent and quality of CEMs on integrated reports. Additional analyses attribute the positive effect of these corporate governance mechanisms on <IR> quality and the use of CEMs mainly to the diligence and expertise of the board of directors and audit committee and the independence and expertise of a sustainability committee.     

Accuracy, unbiasedness and efficiency of professional macroeconomic forecasts: An empirical comparison for the G7

In this paper, we use survey data to analyze the accuracy, unbiasedness and efficiency of professional macroeconomic forecasts. We analyze a large panel of individual forecasts that has not previously been analyzed in the literature. We provide evidence on the properties of forecasts for all G7-countries and for four different macroeconomic variables. Our results show a high degree of dispersion of forecast accuracy across forecasters. We also find that there are large differences in the performances of forecasters, not only across countries but also across different macroeconomic variables. In general, the forecasts tend to be biased in situations where the forecasters have to learn about large structural shocks or gradual changes in the trend of a variable. Furthermore, while a sizable fraction of forecasters seem to smooth their GDP forecasts significantly, this does not apply to forecasts made for other macroeconomic variables.     

Economic insecurity,conservatism, and the crisis of environmentalism: 30 years of evidence

There is an ongoing scientific debate about how environmental concern develops in a population, and under which circumstances it might decline at some point. In this paper, by analysing thirty years of microdata from the German Socio-Economic Panel (SOEP), I investigate the role of socioeconomic factors and political preferences in altering and addressing environmental perceptions in Germany, Europe's green leader. Results from correlated random-effects models reveal, inter alia, that economic insecurity and support for right-wing political parties significantly contribute to lowering environmental concern. Hence, policymakers ought to focus on economic insecurity in order to increase citizens' environmental concern and, eventually, bring an enhancement in pro-environmental behaviour as a result of the voters' political will.     

Alignment mechanisms for supplier-initiated innovation: Results from the logistics service industry

In service outsourcing, buying organizations frequently experience shortcomings in supplier-initiated innovation. To address this problem, we develop a model that distinguishes two mechanisms for buyer-supplier alignment (i.e. relational and formal innovation alignment) and outlines how their effectiveness differs depending on the level of hierarchy in the relationship. Using data from the logistics service industry, it is shown that when the level of hierarchy is comparatively low, where buyers and suppliers interact participatively, both relational and formal innovation alignment are effective in fostering supplier-initiated innovation. Yet, as the relationship becomes more hierarchical and dominated by the buyer, the effect of relational innovation alignment diminishes and eventually turns negative, while the effect of formal innovation alignment is strengthened.
