Social networks,employment and worker discouragement: Evidence from South Africa

Social networks are increasingly being recognized as having an important influence on labour market outcomes, since they facilitate the exchange of job related information. Access to information about job opportunities as well as perceptions about the buoyancy of the labour market depend critically on the social structures and the social networks to which labour market participants belong. In this paper, we examine the impact of information externalities generated through network membership on labour market status. Using Census data from South Africa, a country characterized by high levels of unemployment and worker discouragement, we adopt an econometric approach that aims to minimise the problems of omitted variable bias that have plagued many previous studies of the impact of social networks. Our results suggest that social networks may enhance employment probabilities by an additional 3–12%, and that failure to adequately control for omitted variables would lead to substantial over-estimates of the network co-efficient. In contrast, the impact of social networks on reducing worker discouragement is much smaller, at between 1 and 2%.     

Is coworker feedback more important than supervisor feedback for increasing innovative behavior?

A growing body of research explores human resource management practices that encourage employees to innovate. In this study, we examine the links between different sources of feedback (supervisor and coworker) and employees’ innovative behavior. Drawing on social exchange theory and the job demands‐resources theory, we first propose that work engagement and psychological contract breach mediate the relationship between supervisor feedback and employees’ innovative behavior. Second, we propose a moderated mediation model in which coworker feedback attenuates the relationships between supervisor feedback and employees’ innovative behavior through the mediating mechanisms of both work engagement and psychological contract breach. Using three waves of multisource data from 300 Chinese employees and their 64 supervisors, we found a dual‐mediation pathway by which employees’ work engagement and perceptions of psychological contract breach mediate the influence of supervisor feedback on innovative behavior. Our results also show that coworker feedback can be used to supplement the lack of supervisor feedback when required. Organizations are advised to ensure that employees obtain regular feedback from multiple sources because such feedback can promote employees’ work engagement and perceptions that the organization is upholding its side of the psychological contract, which fosters employees’ innovative behavior.     

Crossing the level of employee's performance: HPWS,affective commitment,human capital,and employee job performance in professional service organizations

Extant research on high-performance work systems (HPWS) has primarily examined the effects of HPWS on firm-level performance from a macro perspective and mostly in manufacturing settings. This study extends this literature by integrating social exchange theory and human capital theory perspectives to examine how shop-level HPWS affect employee individual performance in the service context, especially focusing on the small-scale professional service organizations. Data collected from multiple sources included 97 hair salon shop owners and 284 hairdressers as well as objective job performance measured in terms of each hairdresser's average monthly service sales. Results from cross-level analysis indicated that the relationship between shop-level HPWS and employee job performance was mediated by employee affective commitment and their human capital. These findings shed new light on the mechanisms through which HPWS impact employee outcomes and serve to bridge between macro and micro perspectives of human resource management.     

The influence of supply network structure on firm innovation

In this study, we examine the structural characteristics of supply networks and investigate the relationship between a firm's supply network accessibility and interconnectedness and its innovation output. We also examine potential moderating effects of absorptive capacity and supply network partner innovativeness on innovation output. We hypothesize that firms will experience greater innovation output from (1) higher levels of supply network accessibility and supply network interconnectedness, (2) the interaction between the levels of these two structural characteristics, (3) the moderating role of absorptive capacity on supply network accessibility and the moderating role of supply network partner innovativeness on supply network interconnectedness. Supply network partner relationships are drawn in the context of the electronics industry using data from multiple sources. We use social network analysis to create measures for each supply network structural characteristic. Using regression techniques to test the relationship between these structural characteristics and firm innovation for a sample of 390 firms, our findings suggest that supply network accessibility has a significant association with a firm's innovation output. The results also indicate that interconnected supply networks strengthen the association between supply network accessibility and innovation output. Moreover, the influence of the two structural characteristics on innovation output can be enhanced by a firm's absorptive capacity and level of supply network partner innovativeness. By addressing the need for deeper structural analysis, this study contributes to supply chain research by accounting for the embedded nature of ties in supply networks, and showing how these structural characteristics influence the knowledge and information flows residing within a firm's supply network.     

Job Performance and Turnover: A Review and Integrative Multi-Route Model

Research and theory on the elusive yet important relationship between individual job performance and employee turnover is reviewed. An integrative model of the relationship is proposed which argues that performance may lead to turnover through three different routes. One, performance may influence turnover through cognitive and affective evaluations of the desire to leave the organization. Two, performance may influence turnover through actual and perceived mobility in the job market. Three, performance may lead more directly to turnover in response to performance-related shocks to the system. Additionally, important moderators of these relationships, notably visibility and reward contingency, are highlighted.     

How do industrial relations climate and union instrumentality enhance employee performance? The mediating effects of perceived job security and trust in management

In this study, we examine the effects of two key variables associated with union effectiveness on the job performance of employees, and the mechanisms that explain such effects. More specifically, we investigate whether employees' perceptions that their union has a constructive relationship with management (industrial relations climate) and is able to act as an agent for their concerns (union instrumentality) promotes their job performance by enhancing their perceived job security and trust in management. Drawing on three waves of data from 303 employees and their immediate supervisors within 17 private enterprises in China, we find employees' perceptions of union effectiveness influence their job performance by enhancing both their perceived job security and trust in management. These findings are consistent with social exchange theory and conservation of resources theory. This article contributes to the literature by improving our understanding of how unions influence employees' work performance and by explaining how employees' perceptions of the industrial relations climate and union instrumentality influence their job performance. It also sheds light on the important issue of the effectiveness of unions in China, a country where the centrality of the Chinese Communist Party is often considered to have reduced the instrumentality of unions.     

The pervasive absence of compensating differentials

We study the relation between individual preferences for job amenities (e.g., type of work, job security) and compensating wage differentials in cross‐section. To this end, we estimate a partial equilibrium job search model on panel data from eight European countries. There are five non‐wage job characteristics and two sources of job‐to‐job mobility: on‐the‐job search and reallocation shocks. We also allow for two types of unobserved heterogeneity. We find strong preferences for amenities, especially job security, yet, these preferences do not translate into significant wage differentials in cross‐section. Counterfactual experiments show that one would need extremely low levels of search frictions for compensating differentials to arise. Lastly, a similar exercise on the distribution of job change outcomes reveals the role of constrained job‐to‐job mobility in the absence of compensating wage differentials.

The effect of collaboration network on inventors' job match,productivity and tenure

It has been argued in the economic literature that job search through informal job networks improves the employer–employee match quality. This paper argues that inventors' research collaboration networks reduce the uncertainty of firms about the match qualities of inventors prior to hiring. We estimate the effect of inventors' collaboration networks on their productivity and mobility using the U.S. patent application database. It is found that networked inventors are more productive and have longer tenure than non-networked inventors. The evidence from fixed-effect regressions shows that the higher productivity and longer tenure of networked inventors are not solely attributable to unobserved ability of inventors or unobserved characteristics of firms. These results are consistent with the job match hypothesis between inventors and firms through their collaboration networks.     

Residential mobility with job location uncertainty

This paper investigates the relationship between job changes and residential mobility. A job change may be prompted by reasons unrelated to factors associated with housing consumption. However, a job change may lead to an adjustment to housing consumption, i.e., residential relocation. Previous studies find that job relocations are positively associated with residential mobility. This paper departs from previous studies by looking at the effects of an uncertain future job location on residential mobility and mobility expectation. It is conjectured that with the existence of costs of residential mobility, a household head's likelihood for changing jobs in the future dampens the household's propensity to move, but encourages the formation of mobility expectation. These conjectures are examined empirically using data from the Panel Study of Income Dynamics and they are confirmed.

Actions speak louder than words: how employees mind the implementation gap

Abstract

Integral to employees’ working lives are the HR policies and more importantly, the practices that follow those and their implementation, which employees experience directly. To date, research on HR implementation considers how HRM is ‘done to’ employees by management and therefore ignores the agency of individuals to shape how HRM is ‘done to them’. Taking the perspective of employees, in a qualitative study of female lawyers, this paper examines employees’ roles in shaping HR implementation, addressing a lack of understanding about the role of ‘others’ in the process. Drawing on the concept of social power, the article focuses on the implementation of agile working practices within UK-based law firms. It finds that despite lacking legitimate position power to influence processes, employees draw on a variety of other power sources (e.g. referent, information, coercive) and tactics (e.g. leveraging membership of professional networks) in order to influence their working environment with respect to HR policy and practice, particularly in response to perceived implementation gaps. The current study underlines that employees may be integral to bridging the gap between policy and practice and therefore to ensuring the link between HRM and organisational performance. It also proposes that behavioural responses to HR practices should be considered in future theorising of the HRM-performance relationship.     

Social Networks and Business Success

A bstract .   The main objective of this paper is to illuminate social and cultural preconditions for networking and success in business in an African context. By in-depth studies of small-scale entrepreneurs in the wood business in Tanzania, we find that people belonging to an Asian subculture probably have a better standing for entering and thriving in business, due to group cohesion, mobility, and level of education. Through high-quality social networks, characterized by a high number and variety of relations, certain groups seem to be in a better position to enact their business environment and raise entrepreneurial resources such as motivation and ideas, information, capital, and trust. To reduce social discontent and inter-ethnic and religious conflicts in this area, we suggest that policy measures be taken to enhance levels of education and access to information for all citizens to create a "level playing field" in economic affairs.     

Evaluating information diffusion speed and its determinants in social media networks during humanitarian crises

The rapid diffusion of information is critical to combat the extreme levels of uncertainty and complexity that surround disaster relief operations. As a means of gathering and sharing information, humanitarian organizations are becoming increasingly reliant on social media platforms based on the Internet. In this paper, we present a field study that examines how effectively information diffuses through social media networks embedded in these platforms. Using a large dataset from Twitter during Hurricane Sandy, we first applied Information Diffusion Theory to characterize diffusion rates. Then, we empirically examined the impact of key elements on information propagation rates on social media. Our results revealed that internal diffusion through social media networks advances at a significantly higher speed than information in these networks coming from external sources. This finding is important because it suggests that social media networks are effective at passing information along during humanitarian crises that require urgent information diffusion. Our results also indicate that dissemination rates depend on the influence of those who originate the information. Moreover, they suggest that information posted earlier during a disaster exhibits a significantly higher speed of diffusion than information that is introduced later during more eventful stages in the disaster. This is because, over time, participation in the diffusion of information declines as more and more communications compete for attention among users.     

From London to Los Angeles: a comparison of local labour market processes in the US and UK film industries

Addressing the issue of the embeddedness of labour markets, this paper compares the processes of finding employment in the film industry within two local labour markets. Drawing on studies of freelance film crews in London (UK) and Los Angeles (US), the paper concludes that the importance of social networks in job mobility in both contexts is a consequence of common production structures. However, common labour market practice varies in each geographical space as industry processes and structures are mediated by local institutional contexts.     

Information flows and adaptation in Tanzanian cottage industries

The aim of this research is to identify channels of information flows and their impact on business adaptation and survival. The analysis is set within a theoretical framework of information market failure and information flows. The paper draws on empirical data from a survey comprising approximately 400 small-scale entrepreneurs in dressmaking and woodworking industries at different levels of centrality in four regions in Tanzania. The data reveal that half of the businesses are growing and one-third have increased profitability by significant adaptations last year. Most changes occur in products and design. Customers and the media represent the most important sources of business information, followed by family members and business partners. Independent variables that significantly influence adaptability include customer relations, education, media exposure, social networks, and mobility. Associations are strongly modified by the entrepreneurs’ age and gender and by businesses’ size and location. The paper concludes that cottage industries in Tanzania have a remarkable ability to survive. Garment and woodwork markets are still predominantly local and competition from external businesses is limited. Access to business information and new ideas should be improved, however, to counteract growing competition from the modern sector.     

Forms of cross‐border mobility and social capital in multinational enterprises

This paper discusses how different forms of cross‐border employee mobility all contribute to establishing social ties across different units of multinational enterprises (MNEs). Despite the growing recognition of the significance of employees' cross‐unit social ties in MNEs for both individuals and the organisation, the mechanisms for creating such ties remain underspecified. We contribute to closing this gap by identifying the role that an array of forms of international mobility can play in promoting employees' (cross‐unit) social ties inside MNEs. We draw upon empirical accounts of the job‐related international mobility experiences of 72 high‐skilled employees in three leading MNEs in the mobile telecommunications sector. Guided by a framework that utilizes some of the key concepts of the debate on social ties and social capital, we discuss traditional expatriation, short‐term assignments, localised transfers and business travel in terms of the structure and strength of the cross‐unit ties they engender, as well as their accessibility. We find (1) that it is not only traditional long‐term assignments in the form of expatriation that enable individuals to create cross‐unit social ties; and, (2) that different forms of international mobility promote cross‐unit social ties in variable ways and to different extents.     

Co‐Worker Exclusion and Employee Outcomes: An Investigation of the Moderating Roles of Perceived Organizational and Social Support

When does social support alleviate or exacerbate the effects of being excluded by colleagues in the workplace? This study integrates belongingness and social support theories to predict and demonstrate the differential effects of work‐related support (i.e., perceived organizational support; POS) and non‐work‐related support (i.e., family and social support; FSS) on employee reactions to co‐worker exclusion. Consistent with our predictions, we found that employees reporting high levels of co‐worker exclusion and high levels of perceived organizational support demonstrate higher levels of performance and increased levels of self‐worth than those reporting low levels of POS. Alternatively, support from family or friends intensified the negative relationship between co‐worker exclusion and self‐esteem and the positive relationship between co‐worker exclusion and job‐induced tension. Unexpectedly, FSS did not influence the supervisor‐rated task performance of excluded workers, nor did POS mitigate the relationship between co‐worker exclusion and job‐induced tension. Implications for theory, research, and practice are discussed.     

Urban Poverty,Segregation and Social Networks in São Paulo and Salvador,Brazil

General consensus exists concerning the relevance of networks and space in poverty situations, despite a considerable dispute on the prominence of each element. While social‐support and poverty debates highlight the joint importance of space and networks, the research agenda on contemporary communities suggests that networks have recently started replacing space in social integration. These debates mainly consider networks and ties normatively and are restricted to the global North, hampering the formulation of comparative interpretations and more theoretical conclusions. This article discusses the relationship between space, sociability and poverty, based on research results on networks of poor individuals in two major Brazilian metropolises—Salvador and São Paulo. Research indicates the existence of great heterogeneity in the networks of poor individuals, although with substantial differences, on average, to middle‐class individuals. Certain types of networks and sociability are systematically associated with better living conditions, employment and income. Additionally, network mobilization by individuals presents important regularities associated with social mechanisms, understood as regular patterns that trigger or cause certain results. These mechanisms explain to a great extent the heterogeneity of networks, and mediate the individual's access to opportunities and everyday assistance. They therefore contribute decisively to the production (and reproduction) of urban poverty.     

Social networks of female tech-entrepreneurs and new venture performance: the moderating effects of entrepreneurial alertness and gender discrimination

The social networks of entrepreneurs are an important factor affecting new venture performance. Based on the survey data of 316 new ventures in China, this paper explores the relationship between the social networks of female tech-entrepreneurs and new venture performance, and examines the moderating effects of entrepreneurial alertness and gender discrimination on this relationship. Our findings reveal that: (a) the social networks of female tech-entrepreneurs have a positive effect on new venture performance; (b) the entrepreneurial alertness of female tech-entrepreneurs has a positive effect on new venture performance; and (c) gender discrimination against women has a negative effect on new venture performance. Moreover, we found that gender discrimination negatively moderates the relationship between the social networks of female tech-entrepreneurs and new venture performance. We also found that entrepreneurial alertness positively moderates the relationship between the social networks of female tech-entrepreneurs and new venture performance. Our findings provide theoretical and practical implications for female technical individuals in the entrepreneurial practice, and shed light on the study of entrepreneurship theory in other emerging economies.     

Toward a broader view of age discrimination in employment-related decisions: a joint consideration of organizational factors and cognitive processes

We propose that organizational factors (structure, values, and technology) influence raters' decision making processes which, in turn, can result in age discrimination in employment-related decisions. Specifically, organizational factors may influence (a) the extent to which jobs become age-typed, (b) the extent to which a worker's age is salient and activates age-associated job stereotypes and (c) the extent to which raters are able to base their employment-related decisions on the perceived match between job and worker information. The practical and theoretical implications of our approach are discussed and directions for future research are offered.
