PurposeThe purpose of this paper is to investigate the effects of personality dimensions (conscientiousness, neuroticism, extraversion, agreeableness, openness to experience, locus of control) on the efficacy of judgmental adjustments of statistical forecasts.Design/methodology/approachThis paper uses a two-level hierarchical linear model to analyze a large data set obtained from an organizational setting (a quick service restaurant chain) that includes 3,812 judgmental adjustments of sales forecasts made by 112 store managers.FindingsThe results indicate that the average forecast accuracy improves as a result of judgmental adjustments, but performance of individual forecasters varies considerably based on their personality. Specifically, the trait of openness to experience tends to improve forecast accuracy while extraversion and external locus of control have negative effects.Originality/valueIntegration of human judgment with analytics algorithms is a major challenge for organizations. Documenting the impact of these traits on forecast accuracy opens the door for forecasting support system design, training, personnel selection and correction strategies that can be applied to judgmental adjustments.

Purpose This study aims to develop insights on how national culture, gender and field of study can influence the impact of entrepreneurship education toward the development of entrepreneurial intention. Design/methodology/approach The entrepreneurship education project gathered data from over 18,000 undergraduate student responses, spanning over 70 countries and 400 universities. The sample used in this research examined eight countries with significantly different national cultures, while a quantitative analysis of a sample of n = 5,033 responses was performed. Beyond correlation analysis, a hierarchical multiple regression model is implemented for intention along with moderation analysis. Findings The statistical analysis reveals robust correlations among several entrepreneurial concepts and national cultural indices. As expected, national culture interweaves with all entrepreneurial concepts and more significantly for students of socially oriented disciplines. Gendera and field of the study appear moderators of causal relationships between entrepreneurial constructs. Exerting a strong influence by culture, entrepreneurial identity appears the most significant explanator of intention. Overall, the emergent pattern suggests entrepreneurship is intentional, but in a socially justified and accepted manner closely related to local cultural norms and institutions. Research limitations/implications Implications pertain to research for entrepreneurial intention and to educators and educational bodies concerning their goal setting for entrepreneurial programs and appropriate scheduling of effective pedagogies. Originality/value The study exploits a large data set from eight countries (Brazil, Colombia, Germany, Lithuania, Malaysia, Mexico, Spain and USA) which permits systematic quantitative search for the influence of culture on the impact of entrepreneurship education. Cross-national studies of entrepreneurship education and the effect of national culture have been scant in literature – a research gap the study responds to. The inclusion of both developing and developed countries contributes in a novel way to a unique understanding of the influence of culture on entrepreneurial concepts through education.

Purpose The purpose of this paper is to examine the relationship between bank diversity and small- and medium-sized enterprise (SME) firm innovation in China to evaluate the impact of recent bank deregulation. Design/methodology/approach Using a large data set that includes 8,143 firm-year observations of 1,122 listed SME firms in China and baseline and robustness regression analyses, the authors identify how bank diversity affects firm innovation and via what economic mechanisms. Potential endogeneity problems are considered and addressed in the design and analysis to minimize research bias. Findings The authors find robust evidence that bank diversity improves firm innovation. Specifically, the findings suggest that the positive effects of bank diversity on firm innovation are only significant for the firms which are more external finance dependent, have fewer growth opportunities and/or located in the provinces having low financial market development. Originality/value This study provides novel evidence and insights into the relationship between banking market structure and the determinants of firm innovation in the Chinese context, as a result of China’s banking deregulation.

Purpose The purpose of this paper is to investigate the impact of market-level uncertainty on dividend and repurchase decisions. Design/methodology/approach Using a large data set over a nearly 50-year period, the author examines the choice to pay dividends and repurchase shares using logit and multinomial logit regressions. Findings Market-level uncertainty (measured by a GARCH estimate of volatility, as well as the Chicago Board Options Exchange Volatility Index) is shown to have a statistically significant impact on firms’ payout policy decisions. This impact is different for dividends and repurchases as well as for firms with differing levels of cash flows. As market uncertainty increases, firms with low cash flow levels tighten dividend policy to conserve cash while firms with high cash flow levels become opportunistic through the use of share repurchases. Practical implications The findings allow investors to better understand the connection between shifts in market-level uncertainty and corporate payout policy, specifically through the differing use of dividends and repurchases. Originality/value While prior literature on payout policy has focused on firm-level determinants, this study demonstrates that market-level uncertainty impacts firms’ payout policy decisions uniquely. Furthermore, this is, to the author’s knowledge, the first study to differentiate by relative cash flow level, demonstrating that not all cash flow levels react in the same manner.

Purpose This paper aims to examine the factors contributing to the helpfulness of online hotel reviews and to measure the impact of manager response on the helpfulness of online hotel reviews. Design/methodology/approach This investigation used a linear regression model that drew upon 56,284 consumer reviews and 10,797 manager responses from 1,405 hotels on TripAdvisor.com for analysis. Findings The helpfulness of online hotel reviews is negatively affected by rating and number of sentences in a review, but positively affected by manager response and reviewer experience in terms of reviewer status, years of membership, and number of cities visited. Manager response moderates the influence of reviewer experience on the helpfulness of online hotel reviews. Research limitations/implications Using the data from hotels in five major cities in Texas, the results may not be necessarily generalized to other markets, but the important role that manager response plays in online reviews is assessed with big data analysis. Practical implications The results suggest hospitality managers should strategically identify opinion leaders among reviewers and proactively influence the helpfulness of the reviews by providing manager response. Additionally, this study makes recommendations to webmasters of social media platforms in terms of advancing the algorithm of featuring the most helpful online reviews. Originality/value This study is at the frontier of research to explain how hotel managers can proactively identify opinion leaders among consumers and use manager response to influence the helpfulness of consumer reviews. Additionally, the results also provide new insights to the influence of reviewer demographic background on the helpfulness of online reviews. Finally, this study analyzed a large data set on a scale that was not available in traditional guest survey studies, responding to the call for big data applications in the hospitality industry.

The Impact

Purpose – The purpose of this paper is to investigate client influence on mortgage valuation in Nigeria to establish and rank the means of influence clients employ, and the impact of firm characteristics on client influence. Design/methodology/approach – A combination of cross-sectional survey and focus groups research designs was adopted. Questionnaire structured on five-point Likert format was used to collect data from a sample of valuation firms in five Nigerian cities. Descriptive statistics, χ2, and moderated hierarchical linear model were used for data analysis. Findings – Clients’ means of influence on valuation are more of subtle approach than threat or coercion. The most prevalent means are respectively, plea for assistance, promise of continued retainership on banks’ valuer panels, and disclosing the loan amount. Client influence differs across cities; firm characteristics have no influence on client pressure. Practical implications – The research provides basis for valuation bodies to review practice rules and standards and seek for legislation for valuer independence. It can serve as material for teaching and training in professional ethics. Social implications – Biased valuations jeopardises credit risk mitigation process with potential for destabilising banks, finance sector, and consequences for the economy. Originality/value – The study provides empirical evidence of the nature of client influence across several major Nigerian cities. In contrast to existing Nigerian studies that focus on single cities, the study covers several cities. It therefore provides a broad basis for problem-solving and decision-making.

Simulation Exercises

Purpose – Church giving and attendance are two important indicators of church health and performance. In the literature, they are usually understood to be simultaneously determined. The purpose of this paper is to estimate if there a sustainable church congregation size using Wintrobe’s (1998) dictatorship model. The authors want to examine the impact of youth and adult ministry as well. Design/methodology/approach – Using the data collected from among Canadian Baptist churches in Eastern Canada, this study investigates the factors affecting the level of the two indicators by the panel-instrumental variable technique. Applying Wintrobe’s (1998) political economy model on dictatorship, the equilibrium level of worship attendance and giving is predicted. Findings – Through various simulation exercises, the actual church congregation sizes is approximately 50 percent of the predicted value, implying inefficiency and misallocation of church resources. The paper concludes with insights on effective ways church leaders can allocate scarce resources to promote growth within churches. Originality/value – The authors are the only researchers getting the permission from the Atlantic Canada Baptist Convention to use their mega data set on church giving and congregation sizes as per the authors’ knowledge. The authors are also applying a theoretical model on dictatorship to religious/not for profits organizations.

Password Security

Purpose – Passwords have been designed to protect individual privacy and security and widely used in almost every area of our life. The strength of passwords is therefore critical to the security of our systems. However, due to the explosion of user accounts and increasing complexity of password rules, users are struggling to find ways to make up sufficiently secure yet easy-to-remember passwords. This paper aims to investigate whether there are repetitive patterns when users choose passwords and how such behaviors may affect us to rethink password security policy. Design/methodology/approach – The authors develop a model to formalize the password repetitive problem and design efficient algorithms to analyze the repeat patterns. To help security practitioners to analyze patterns, the authors design and implement a lightweight, Web-based visualization tool for interactive exploration of password data. Findings – Through case studies on a real-world leaked password data set, the authors demonstrate how the tool can be used to identify various interesting patterns, e.g. shorter substrings of the same type used to make up longer strings, which are then repeated to make up the final passwords, suggesting that the length requirement of password policy does not necessarily increase security. Originality/value – The contributions of this study are two-fold. First, the authors formalize the problem of password repetitive patterns by considering both short and long substrings and in both directions, which have not yet been considered in past. Efficient algorithms are developed and implemented that can analyze various repeat patterns quickly even in large data set. Second, the authors design and implement four novel visualization views that are particularly useful for exploration of password repeat patterns, i.e. the character frequency charts view, the short repeat heatmap view, the long repeat parallel coordinates view and the repeat word cloud view.

PurposeThis paper aims to examine the critical role played by cultural flow in fostering successful expatriate cross-border transitions.Design/methodology/approachThe authors develop and test a model on the interplay among cultural intelligence, organizational position level, cultural flow direction and expatriate adaptation, using a data set of 387 expatriate on cross-border transitions along the Belt & Road area.FindingsThe authors find that both organizational position level and cultural flow moderate the relationship between cultural intelligence and expatriate adaptation, whereby the relationship is contingent on the interaction of organizational position status and assignment directions between high power distance and low power distance host environments.Originality/valuePrevious research has shown that higher levels of cultural intelligence are positively related to better expatriate adaptation. However, there is a lack of research on the effect of position difference and cultural flow on such relationship. Our study is among the first to examine how the interaction between cultural flow and organizational position level influences the cultural intelligence (CI) and cultural adjustment relationship in cross-cultural transitions.

Purpose The purpose of this paper is to analyse the impact of intellectual capital (IC) on the reputation and performance of Italian companies. Design/methodology/approach The paper exploits a unique data set of 452 non-listed companies that obtained a reputational assessment from the Italian Competition Authority (ICA). To test the hypotheses, this study implemented several regression analyses. Findings Results support the argument that human capital efficiency is a key driver of corporate reputation. Findings also reveal that companies, which obtained reputational rating under ICA scrutiny, show a positive relationship between IC elements and various measures of financial performance. Research limitations/implications The study focuses on a single country; it is not free from the imprecisions of Pulic’s VAIC model. Practical implications This paper recommends companies that are interested to achieve a robust reputation should consider the human capital as a strategic intangible asset. Second, the results suggest that companies with an ICA reputational rating are able to leverage their intangibles to potentiate performance and competitiveness. Originality/value This is the first empirical investigation on the contribution of IC in generating value for corporate reputation. Additionally, the study contributes to the literature on the link between IC and performance by examining a sample of firms not yet explored in prior research.

Indian Banks

Purpose This paper aims to examine the interplay between risk, capital and efficiency of Indian banks and study how their relationship differs across different ownership types. Design/methodology/approach Panel regression techniques are used to analyze a large data set of all Indian scheduled commercial banks operating during the period 2008-2016. Findings The results show that lower efficiency is associated with higher credit risk in the case of public sector and old private sector banks (”bad management hypothesis”). However, higher efficiency leads to higher credit risk in the case of foreign banks (“cost skimping hypothesis”). The authors further find that the more efficient institutions among public sector hold more capital. Finally, they find that the better-capitalized banks among those in the public sector have lower risks on their balance sheets (“moral hazard hypothesis”). Originality/value There is a paucity of papers on the interplay between risk, capital and efficiency of banks in emerging economies. This paper is the first to study the inter-relationship between risk, capital and efficiency of Indian banks across ownership groups using a number of different measures of risk.
