Abstract
Purpose
This paper aims to popularize the Bayesian methods among novice management researchers. The paper interprets the results of Bayesian method of confirmatory factor analysis (CFA), structural equation modelling (SEM), mediation and moderation analysis, with the intention that the novice researchers will apply this method in their research. The paper made an attempt in discussing various complex mathematical concepts such as Markov Chain Monte Carlo, Bayes factor, Bayesian information criterion and deviance information criterion (DIC), etc. in a lucid manner.
Design/methodology/approach
Data collected from 172 pharmaceutical sales representatives were used. The study will help the management researchers to perform Bayesian CFA, Bayesian SEM, Bayesian moderation analysis and Bayesian mediation analysis using SPSS AMOS software.
Findings
The interpretation of the results of Bayesian CFA, Bayesian SEM and Bayesian mediation analysis were discussed.
Practical implications
The management scholars are non-statisticians and are not much aware of the benefits offered by Bayesian methods. Hitherto, the management scholars use predominantly traditional SEM in validating their models empirically, and this study will give an exposure to “Bayesian statistics” that has practical advantages.
Originality/value
This is one paper, which discusses the following four concepts: Bayesian method of CFA, SEM, mediation and moderation analysis.

Abstract
Purpose
The purpose of this paper is to examine the effects of atmospherics and affective state on shoppers’ in-store behaviour using the two approaches in structural equation modelling (SEM), i.e. Frequentist and Bayesian approaches. Shoppers’ affective state was tested for its mediating effect on in-store shopping behaviour.
Design/methodology/approach
The final sample consists of 382 respondents who were drawn from shoppers at selected apparel stores in six of the most popular shopping malls around Kuala Lumpur (Malaysia). A frequentist approach to SEM is common among researchers and offers generally an analysis of the relationships between multiple latent variables and constructs. Alternatively, the Bayesian SEM (BSEM) approach stems from the diffusion of the model’s posterior distributions using the Markov Chain Monte Carlo technique. More specifically, this technique is inherently more flexible and substantive in determining parameter estimates as compared to the more conventional, the frequentist approach to SEM.
Findings
The results show the mixed effects of atmospheric cues in retail setting on shoppers’ affective state. More specifically, the positive direct effect of atmospheric cues (music) on in-store behaviour was confirmed while other atmospheric cues (colour and store layout) were found to be fully mediated by affective state. The Bayesian approach was able to offer more distinctive results complementing the frequentist approach.
Research limitations/implications
Although the current sample size is adequate, it will be interesting to examine how a bigger sample size and different antecedents of in-store behaviour in retailing can affect the comparison between the frequentist approach in SEM and BSEM.
Practical implications
The authors found that a combination of well-designed store atmospherics and layout store can produce pleasurable effects on shoppers resulting in positive affective state. This study found that results from both frequentist and Bayesian approaches complement each other and it may be beneficial for future studies to utilise both approaches in SEM.
Originality/value
This paper met the aim to compare the approaches in SEM and the need to consider both approaches on in-store shopping environment. Overall, the authors contend that the Bayesian approach to SEM is a potentially viable alternative to frequentist SEM, especially when studies are conducted under dynamic conditions such as apparel retailing.

This paper aims to present several Bayesian specification tests for both in- and out-of-sample situations.
Abstract
Purpose
This paper aims to present several Bayesian specification tests for both in- and out-of-sample situations.
Design/methodology/approach
The authors focus on the Bayesian equivalents of the frequentist approach for testing heteroskedasticity, autocorrelation and functional form specification. For out-of-sample diagnostics, the authors consider several tests to evaluate the predictive ability of the model.
Findings
The authors demonstrate the performance of these tests using an application on the relationship between price and occupancy rate from the hotel industry. For purposes of comparison, the authors also provide evidence from traditional frequentist tests.
Research limitations/implications
There certainly exist other issues and diagnostic tests that are not covered in this paper. The issues that are addressed, however, are critically important and can be applied to most modeling situations.
Originality/value
With the increased use of the Bayesian approach in various modeling contexts, this paper serves as an important guide for diagnostic testing in Bayesian analysis. Diagnostic analysis is essential and should always accompany the estimation of regression models.

Abstract
Purpose
This paper aims to propose a multi-dimensional model on the basis of the key factors of the flexibility and the complexity through structural equation modeling (SEM). Dimensions of the flexibilities and complexity, including 16 main factors and 34 sub-factors, are investigated. The sampling of the research is accomplished using both academic and industrial experts.
Design/methodology/approach
A huge electronic questionnaire analysis, including 1,250 samples from which 1,036 were returned, was accomplished in various universities and manufacturing companies throughout the USA, Europe and Asia. Partial least square-SEM (PLS-SEM) is used to test the hypotheses through confirmatory factor analysis.
Findings
The results reveal insightful information about the impacts of different dimensions of flexibility on each other and also the effect of the flexibility on the complexity. Finally, system of linear mathematical equations for flexibility-complexity trade-off is proposed. This can be applied to realize the trade-off among dimensions of flexibility and complexity.
Originality/value
Flexible manufacturing systems are formed to meet the needs of the customers. Such systems try to produce products in appropriate quality at the right time and at the specified quantity. These, in turn, require flexibility and will cause complexity. Although flexibility and complexity are both important, there is no comprehensive framework in which the multi-dimensional relationships of the manufacturing flexibility and complexity, as well as their dimensions, are demonstrated.

This study aims to investigate the effects of environmental risk perception on the evaluation of socioeconomic development and subjective well-being in China.
Abstract
Purpose
This study aims to investigate the effects of environmental risk perception on the evaluation of socioeconomic development and subjective well-being in China.
Design/methodology/approach
A questionnaire survey was conducted, and data were collected from 408 participants of four major universities and government organizations in Changsha, China. Structural equation modeling (SEM) was used to analyze the collected data and to test the hypotheses with regard to the relationship among latent variables. Bayesian method was used as the statistical inference procedure.
Findings
Results show that environmental risk perception has a direct negative influence on perceived socioeconomic development and on subjective total well-being (i.e. both hedonic and eudaimonic well-being). The perceived socioeconomic development has a direct positive effect on the subjective total well-being; thus, it plays a partial mediation role between environmental risk perception and subjective total well-being.
Research limitations/implications
Findings suggest that the environment protection act of the government and their contribution to socioeconomic development will significantly affect the total well-being of people. The empirical analysis is based on survey data; thus, this study may suffer the common problems of questionnaire survey.
Social implications
Promoting pro-environment and health behaviors is important in developing a happy society.
Originality/value
This study demonstrates a significant negative effect of environmental risk perception on the total well-being of people according to SEM approach. This study determines two independent paths for government and policy makers to increase the total well-being of people in China, namely, increasing socioeconomic value to people and controlling and reducing environmental threats.

Abstract
Purpose
The purpose of this paper is to draw on self‐categorisation theory and nation branding to investigate the social identities and influences which underpin consumer preferences for national brands.
Design/methodology/approach
A survey in Mozambique, an underdeveloped African country, compared a domestic mobile phone company whose brand contains the country name against a European brand. Consumer ethnocentrism might arise identifying with the national brand or with Mozambican personalities endorsing the brand. Value‐expressiveness might arise from consumers associating with celebrity endorsers. A dichotomy of youth versus older consumers moderated the relationships between social identities and brand preference. Bayesian structural equation modelling using Monte Carlo simulations estimated the path coefficients from a sample of 611.
Findings
Across age groups, ethnocentrism is stronger than value‐expressiveness in determining preference for national brands. Moreover, ethnocentrism is stronger with the older rather than younger consumers. Consumer ethnocentrism stemmed mainly from injunctive influence (IN) with both age groups. With older consumers, value‐expressiveness related significantly to descriptive influence, but not to IN. With youth, neither social influence significantly related to value‐expressiveness.
Research limitations/implications
Single‐item measures might be less effective than multi‐item measures for psychological concepts of social identities and influences.
Practical implications
Understanding the role of social identity in consumer preferences for national brands may help managers heighten consumers' social identities and increase their loyalty for national brands. Shedding light on under‐researched African consumers may help firms doing business in these emerging markets as well as African governments that are attempting to strengthen the perceptions of their nation brand.
Originality/value
This paper bridges research in social psychology and international marketing by investigating the social identities and influences that underpin consumer preferences for national brands.

Abstract
Purpose
The purpose of this paper is to explain how internal and external sources of knowledge influence the innovation performance (IP) in Italian manufacturing firms and how different these relationships are for low-technology (LT) and high-technology (HT) firms.
Design/methodology/approach
The study proposed a model relating external knowledge, internal knowledge and IP that was tested using Bayesian structural equation modeling with a sample of Italian manufacturing firms of Community Innovation Survey 2010. It was run separately for high-tech firms (including HT and medium-HT aggregations of manufacturing industries of NACE Rev. 2) and low-tech firms (including LT and medium-LT aggregations).
Findings
The results showed a difference between high-tech and low-tech manufacturing firms in Italy. The investments to leverage internal knowledge sources are important for high-techs and not significant for low-techs. On the other hand, the level of external KS improves significantly the IP of low-techs and has a negative effect for high-techs. The level of absorptive capacity is central to improve the positive effect of the external knowledge on the IP for all firms, but it is still underdeveloped.
Originality/value
The effects of 2008 economic crisis hit the Italian manufacturing industry specifically hard and are still felt. Innovation is a solution for firms’ growth and Italy is considered a below-average innovator country in Europe. The study could identify important gaps in Italian manufacturing firms that hinder their innovative performance improvement.

Abstract
Purpose
The global fashion industry is growing at a rapid pace and developing nations such as India are emerging as major contributors to the same. In such case, most academics and marketers are interested in the variables that influence fashion shopping. The purpose of this paper is to investigate the influence of consumer demographic and personality characteristics on fashion shopping proneness (FSP) in India.
Design/methodology/approach
Data were collected from 561 respondents using mall intercept survey method. Hypothesized relationships were assessed using multiple regression and structural equation modelling.
Findings
Traditional view that younger and female consumers are more fashion prone than older and male consumers is validated. However, demographics accounted for only 9 per cent of the variance in FSP while personality characteristics accounted for 46 per cent. Being agreeable, extroverted, open minded, and stable are all positively associated with fashion shopping.
Research limitations/implications
The study finds both personality dimensions and consumer demographics to influence FSP. As a limitation, the authors do not probe deep into the why and how of the mentioned relationships between personality and fashion buying.
Practical implications
With respect to demographics, managers could target young females as the primary segment for fashion clothing but cannot ignore young males and older females. With respect to personality, managers can appeal to agreeable, extroverted, open-minded personalities by linking novelty, fun, relaxation, and recreation with fashion buying.
Originality/value
This is one of the first attempts that simultaneously investigates the effects of demographic and personality characteristics on fashion shopping behaviour in India.

Abstract
Purpose
The purpose of this study is to examine the changes in global worker preferences for job attributes and incentives at the national cultural level, knowledge that is key to the architecture of effective human resource systems.
Design/methodology/approach
A Bayesian latent growth curve (LGC) model was used to test data from the World and European Values Surveys from the time periods 1981 to 2005.
Findings
Results (based on Bayesian LGC analysis) indicate that employee-related beliefs about what is attractive in a job do change considerably over time, with pay, then employment security having the highest priorities. Equally important, demand for good pay and a job that matches one’s abilities are the fastest growing global worker desires.
Originality/value
These findings of national culture’s active evolution in the workplace indicate a need for scholars, leaders in practice – especially human resource managers – to rethink our cultural conceptualizations for model building and global job design and reward systems.
