PurposeThis paper contributes to the literature concerning the Nigerian informal economy (IE) by estimating its size from 1991 to 2017 and identifying the major causes.Design/methodology/approachA structural equation approach in the form of the multiple indicators multiple causes (MIMIC) method is used to estimate the size of the Nigerian IE.FindingsThe results indicate that vulnerable employment and urban population as a percentage of the total population are the main drivers of the IE in Nigeria. The IE in Nigeria ranges from 38.83% to 57.55% of gross domestic product (GDP).Research limitations/implicationsAs a result of the empirical challenges in the estimation of the IE, the estimates of Nigeria's IE are considered to be rough estimates.Originality/valueThe authors calibrated the MIMIC model with the official estimate of the informal sector published by the Nigerian National Bureau of Statistics (NBS). This was an attempt to combine the national accounting approach, to estimate the size of IE, with the MIMIC approach, and to estimate the trend of informality.

Abstract China is experiencing a large increase in elderly population. In 2019, China’s population aged 60 and above had reached 253 million, accounting for 18.1% of the total population (National Bureau of Statistics of China, 2020). By 2050, the number of adults aged 60+ would be up to 430 million, reaching one third of the total population (Du, Zhai & Chen, 2005). Considering such a rapid aging process and the existing large number of older adults in China, it becomes imperative to investigate how psychosocial factors affect this group’s subjective well-being. This study proposed that, among older adults, higher support received from each of the three relational sources (adult children, family and friends) were associated with reduced loneliness and improved well-being. Structural equation modeling was conducted using a sample of rural adults aged 60 and older (N= 1142) from the 2018 wave of data from the Longitudinal Study of Older Adults in Anhui Province, China. Findings indicated that support from adult children directly and indirectly decreased older adults’ depression and improved their life satisfaction through loneliness; while support from family members directly decreased depression but did not directly improve life satisfaction or indirectly improve well-being through loneliness. Although support from friends did not have a significant impact on older adults’ well-being, it indirectly improved well-being through reduced loneliness. Findings have implications for programs or interventions targeting both parent -adult-child support and friends support and reducing rural older adults’ loneliness.

Purpose The purpose of this paper is to determine the effect of the co-alignment of structural variables on innovation, wherein Bogotá-based SMEs, belonging to the industrial, commercial and services sectors, were used as samples. Design/methodology/approach The study was conducted using a causal inference methodology and through the application of a structural equation model. Findings The results indicate that organizational structure has an influence on innovation, although this is true only for some variables and only when the analysis is performed separately. When performed under strategic co-alignment conditions, however, its influence becomes greater. Originality/value Organizational structure and innovation are determining factors of organizational performance. Although the strategic co-alignment theory has provided points of reference to understanding the phenomenon of organizational performance, there are still many gaps left to be filled. Additionally, it also requires empirical validation especially in relation to Colombian SMEs – and this is where this work makes a contribution.

Purpose – The purpose of this paper is to test the properties of the well-known three-dimensional adjustment scale, established by Black et al. (1988, 1989), namely, its dimensionality and internal consistency. The theoretical basis of the construct is discussed in relation to formative and reflective measurement approaches. Design/methodology/approach – Two different ways of organizing the adjustment items (random/non-random) were used to assess the internal consistency of the three-dimensional adjustment scale. The quantitative analysis presented is based on survey data from 468 assigned expatriates in Asia that were subjected to an exploratory and confirmatory factor analysis as well as a structural equation modeling – more specifically the multiple indicators multiple causes model (MIMIC). Findings – The study revealed that the adjustment construct is possibly misspecified, especially the general adjustment dimension, that was tested as a formative, not a reflective scale. There is further evidence that the wrong measurement approach skewed the coefficient that connects adjustment to performance, which is the key construct in its nomological network. Moreover, the dimensionality and the internal consistency of the scale are deteriorated to a large extent by randomization of the items. The findings highlight the need for a clear concept definition that would lead to an appropriate operationalization of the construct. Originality/value – The study is one of the few rigorously testing the properties of a construct that has been used for almost 30 years, thus yielding some novel conclusions about its stability and consistency.

Purpose Consumers can face a situation of information asymmetry in electronic shopping (ES). The purpose of this paper to examine the relationships between: relational variables such as satisfaction, trust and perceived opportunism; and website cues (cognitive signals such as security and personalization, and experiential signals, such as design and entertainment). Design/methodology/approach The paper opted for the structural equation methodology to analyze data collected from 447 Spanish e-shoppers. Findings Results show different factors that relate to satisfaction, trust and perceived opportunism in ES. Satisfactory experience with ES and entertainment emerge as the most relevant factors to achieve trust and prevent perceived opportunism in e-commerce. Originality/value The five contributions of this study are: the introduction of variables from several theoretical approaches to the study of an agency problem in e-commerce; the study of different ways to gain buyer trust and reduce perceived opportunism in an electronic shopper-vendor relationship; the application of signaling theory as part of the process of helping the principal (e-shopper) to solve their shopping problem in a context of information asymmetry; the analysis of the impact of external cues from e-vendor/site, which allows for a comparison between internal experiences and external quality signals; and the study of entertainment as an important hedonic variable in order to have satisfied and confident e-shoppers.

Purpose – Several authors in extant literature have shown concern towards lacuna in availability of standard constructs in supply chain management (SCM). These standard constructs can represent pillars of SCM excellence. However, frameworks on SCM excellence unlike its contemporary fields are very few. Thus the purpose of this paper is to develop a path analysis for proposed framework of SCM excellence in Indian manufacturing industry proposed by Soni and Kodali (2014) using interpretive structural modelling (ISM) and structural equation modelling (SEM). Design/methodology/approach – The ISM is performed on two exemplary cases of supply chain in Indian manufacturing industry. These cases were selected on the consideration of supply chain excellence index (SCEI), based on the results of an empirical study conducted by Soni and Kodali (2014) in Indian manufacturing industry. The focal manufacturing company which exhibited lowest and highest SCEI were selected as contenders for developing ISM. The relationships among pillars and constructs of SCM excellence framework are obtained from ISM, and later are subjected to statistical testing of model fit by using SEM. The input to SEM was the respondent’s data used in previous study. Findings – The major findings revealed that ISM based on focal company having highest SCEI, is statistically fit for SCM excellence framework, and finally the structural models of the constructs for each pillar of SCM excellence are also formed by using path analysis. Originality/value – The study offers a unique managerial approach for analysing the underlying relationships between pillars of SCM excellence. Researchers can use this study for developing frameworks in various realms of SCM excellence.

Purpose This study aims to investigate the effect of teaching style and academic enthusiasm of Iraqi accounting and auditing students on their stress, aggression and anxiety. Design/methodology/approach The statistical population in this study consists of two parts. The first is the Iraqi accounting and auditing students in Iran and the second is the Iraqi accounting and auditing students in Iraq. By available non-probability sampling method, 62 people (Iraqi students in Iran) and 102 (Iraqi students in Iraq) were selected as samples. In this research, a questionnaire was used to collect information. The validity of the questionnaire’s structure was confirmed by confirmatory factor analysis. Also, Cronbach’s alpha coefficients in this study indicating the measurement tool’s reliability. In this research, structural equation modeling has been used to analyze and test the hypotheses. The primary criteria for determining the coefficient and evaluating the path coefficients were used to evaluate the structural model. Findings Findings indicate that in Iraqi students in Iraq and Iraqi students in Iran, teaching style negatively affects stress, aggression and accounting and auditing students’ anxiety. Also, in the group of Iraqi students in Iraq and the group of Iraqi students in Iran, the eagerness to study has a significant negative effect on accounting and auditing students’ stress and anxiety. In contrast, the effect of the desire to study accounting and auditing students’ aggression was confirmed only in Iraqi students in Iraq. Originality/value As the accounting and auditing professions are among the most stressful occupations that increase the characteristics of aggression and anxiety in the employees of that profession, the results of leading research can show that the stress, anxiety and aggression of accounting and auditing students how to reduce through training so that their stress, anxiety and aggression do not appear in the workplace and the reports of accountants and auditors are not affected.

Practical Implications

Purpose – The purpose of this paper is to explore the potential differences between types of self-service technology. Specifically, the paper explores how the dynamics of public and private self-service technology influence customers' decision to use the technology. Design/methodology/approach – Existing customers of private and public self-service technology were surveyed from the same industry. Using structural equation modeling, the authors examine how relevant self-service constructs influence evaluations and attitudes of customers across both settings. Findings – The analysis reveals that customers' control and convenience perceptions differ across public and private self-service technology. Additionally, customers placed a heavier emphasis on the hedonic or utilitarian evaluation of a service experience based on the type of self-service technology. Practical implications – For managers of self-service applications, understanding the unique differences of public and private self-service technology can aid in the implementation and adoption of the technology. By properly understanding the differences of the self-service types, managers can provide a beneficial experience to the customer. Originality/value – By identifying and describing two distinct categories of SSTs, this study allows managers and researchers to better understand how and why individuals choose to utilize individual self-service technologies. Through understanding the unique dynamics of a public and a private SST experience, retailers can determine the appropriate strategy for customer adoption based on the utilitarian or hedonic functions of the technology.

Purpose The purpose of this study is to compare satisfied and non-satisfied customers in the context of wine tasting rooms using the SERVQUAL model and to examine the relationships in the model in terms of service experience to better understand customer needs. Design/methodology/approach The data used in this study were derived from a survey conducted among wineries in British Columbia, Canada. Analysis of survey results using the partial least squares structural equation modeling was undertaken. Sample size was 402. Findings The findings show that the SERVQUAL constructs that had the most impact on customer satisfaction and dissatisfaction were tangibility and assurance. Somewhat surprisingly, the perceived value for money construct was not significantly related to customer satisfaction but was significantly related to repurchase intent. Furthermore, all SERVQUAL constructs, except the reliability construct, were significantly related to customer satisfaction. Originality/value This study provides an overview of how wineries can improve their services to increase the number of satisfied customers.
