Antecedents and consequences of social capital on buyer performance improvement

The ability to leverage social capital within strategic buyer–supplier relationships is increasingly cited as a key driver of value creation. Despite the importance of strategic partnerships, the process by which social capital accumulates within buyer–supplier relationships and contributes to buyer performance improvements is not well understood. Drawing on social capital theory, we develop a model linking positive relational capital, and its antecedents, supplier integration and supplier closeness, to buyer performance improvements. Further, we hypothesize that structural capital, as reflected in managerial communication and technical exchanges, is also positively related to buyer performance improvements. Using data provided by 111 procurement executives from the United Kingdom, we find support for our hypotheses. The study extends the supply chain management and social capital literature and suggests important implications for both research and practice.     

Social capital and entrepreneurial process

The paper examines the relationship between social capital and entrepreneurial engagement of individuals in 35 nations from Europe and Asia. To the best of our knowledge, this is the first empirical research that attempts to investigate the influence of three-dimensional social capital concept – trust, networks and norms – on three stages of entrepreneurial process – preference, trial and success – using such large and comprehensive cross-sectional micro data. In general, we find that all three dimensions of social capital matter in the entrepreneurship context, albeit differently. They become beneficial in different ways and at different stages of entrepreneurial involvement. For example, among trust variables, institutional trust in general, and trust in business-oriented and business-supporting actors in particular, exert significant positive effect on entrepreneurial process. Individuals with formal membership in professional associations are more likely to perceive entrepreneurial opportunities, while some close or strong-tie networks might prevent them from progressing in the entrepreneurship ladder. Finally, individual level civic norms appear to be negatively associated with early-stage entrepreneurship, while the success in becoming an entrepreneur is not found to be bound by people’s civic norms.     

Social capital effects on the discovery and exploitation of entrepreneurial opportunities

Social capital refers to social networks and the norms of reciprocity, cooperation and trust associated with them. It can be studied at different levels of analysis. As previous literature suggests, social capital has aspects at both the individual and collective levels. However, theory development and empirical research have focused on separate, sometimes diverging levels. In an attempt to address this, this research examines the simultaneous influence of individual and regional social capital on the discovery and exploitation of entrepreneurial opportunities using individual-level data from the Global Entrepreneurship Monitor linked with regional-level data on social capital. The results show that individuals from regions with higher social capital are more likely to discover and to exploit entrepreneurial opportunities. Moreover, individuals having networks with other entrepreneurs are also more likely to identify a business opportunity and to become an entrepreneur. Also, we found that social capital at individual level had a greater effect than social capital at regional level in the two stages of the entrepreneurial process.     

Project success and project team management: Evidence from capital projects in the process industries

Efficient project execution is a key business objective in many domains and particularly so for capital projects in the process industries, but existing project management research gives little direction about how project team factors influence three important capital project outcomes: cost, schedule, and operability. After an extensive cross-disciplinary review of the general team and project management literatures, we constructed and tested a theoretically based, five-dimensional model of organizational context, project team design, project team leadership, project team processes, and project outcome factors. We examined the model by means of an empirical study of 56 newly completed capital projects executed by 15 Fortune 500 companies in the process industries. The results indicate the value of disaggregating project outcomes for research purposes. Different bundles of project team factors were found to drive project cost, schedule, and operability. Project team efficacy, cross-functional project teams, autonomous project team structure, and virtual office usage were the strongest predictors of project cost effectiveness. Continuity of project leadership, cross-functional project teams, and project manager incentives were the strongest predictors of project construction schedule. In contrast, clear project goals and an office design to facilitate effective communication were the main predictors of plant operability. Implications of these findings for researchers and project practitioners are discussed. One major practical implication of our findings is that project managers need to clearly focus and prioritize their goals for each project so they can adopt the appropriate bundles of project team practices that will facilitate their goal achievement.     

Demographic diversity in the workplace and its impact on employee voice: the role of trust in the employer

Abstract

This article examines the relationship between demographic diversity principles and evaluations of employee voice. An analysis of survey data from 707 employees working at 37 hospitality institutions with different star categories confirmed that trust in the employer, followed by the modest contribution of education, is of the utmost importance in the evaluation of voice systems by all employees. Employee evaluations of voice opportunities were found to display differences between male and female employee groups. While generational cohort was a differentiating attribute for the male group, job tenure had the same effect for the female employees. Implications for future research and for HR managers are discussed.

Social capital and career outcomes: a study of Chinese employees

This study examines the impacts of social capital on employees’ career outcomes in the Chinese context. Access to information and access to resources are hypothesized as the mediators in the relationships. A new measure of individual social capital is developed and used as the key predictor of the outcome variables. Data were collected from a survey administered to 184 employees in a state-owned enterprise. The results of regression analysis showed that individual social capital enhanced both career satisfaction and career achievement among Chinese employees. Further, access to information and access to resources were found to mediate the above relationships. The theoretical and practical implications are discussed.     

Caught in the web: the dual nature of networks and its consequences

Relations between a firm and organizations in its political and economic environment are increasingly seen as crucial for the successful functioning of that firm, both in the narrow economic sense, and at the broader level of reaching sustainability. However, attention seems to be focused on the positive qualities of such networks of organizations. In this paper it is argued that networks of organizations have a dual nature, and do not just provide possibilities for collective learning and problem solving. At the same time, such networks consist of dependency relations that provoke power strategies, which result in outcomes reflecting the distribution of power rather than leading to an optimal result. By means of a case study, this dual nature is explored. It is shown that the actors involved in the process of developing an alternative to the disposable milk carton in the Netherlands are embedded in dependency relations. Several of these actors attempt to create problem solving networks, and succeed. However, the already existing dependency relations between the actors involved influence the direction, outcome, and timing within these networks. Using criteria for network performance, this dual nature of networks is assessed. © 1998 John Wiley & Sons, Ltd and ERP Environment.     

The effect of capital wealth on optimal diversification: Evidence from the Survey of Consumer Finances

It is well known that the wealthier the household, the larger tends to be the proportion of its total capital portfolio allocated to publicly traded stock, and the larger tends to be the number of individual stock issues included in its portfolio. Using the “homogeneous securities” case of a mean-variance model originally proposed by Michael Brennan, explicit functional forms are obtained for both the optimal proportion of the portfolio allocated to stocks and the optimal number of individual stock issues in the portfolio. An empirical evaluation of these theoretical results, using a dataset derived from the 2004 Survey of Consumer Finances, lends substantial support to the model.

No man is an island: Social and human capital in IT capacity building in the Maldives

In many developing countries, lack of IT skills and human capital impede the potential of IT investments in organizations in developing countries [Lee, J. (2001). Education for technology readiness: Prospects for developing countries. Journal of Human Development, 2(1), 115–151]. This paper draws upon theories of human and social capital, and knowledge, to explain enablers/obstacles for knowledge creation and transfer for IT capacity building in a tourism organization in a developing country – the Maldives. IT capacity building is intimately linked to knowledge and skills at the level of human resource development. Using the Nahapiet and Ghoshal (1998) [Nahapiet, J., & Ghoshal, S. (1998). Social capital, intellectual capital, and the organizational advantage. Academy of Management Review, 23, 242–267] framework for the role of social capital in knowledge creation and transfer, we examine the major issues of IT capacity building for the case organization. We conclude that the role of cognitive capital is the most important for the tourism sector of the Maldives, and may play a vital role in accumulating structural and relational capital, together with appropriate government policies on ICT.     

Social capital configuration, legal bonds and performance in buyer-supplier relationships

Academics have increasingly recognized the benefits derived from social networks embedded within companies’ buyer-supplier relationships. However, prior research has only examined the influence of social capital elements on performance, either individually or in part. We propose an integrative model examining the relationships among relational, structural and cognitive dimensions of social capital, and between these dimensions and the cost and innovation performance of the firm. A sample of 163 buyer-supplier relationships is used to test the model. Regression results indicate that the relational dimension of social capital fully or partially mediates the effect of the cognitive dimension on performance, and partially mediates the link between the structural dimension, operationalized as social interaction ties, and innovation performance. Further, high levels of legal bonds were found to moderate the relationship between the relational dimension of social capital and performance outcomes. Implications for theory and managers are discussed.     

Legalization of drugs: Effects on the workplace

In the last few years bipartisan support for legalizing drugs has grown to a surprising level. Because of the lack of involvement of the business community in this debate, we surveyed the human resource managers of 127 firms about their perceptions of the effects of legalization. Their responses were uniformly negative, with expectations that drug use, absenteeism, worksite crime, and liability costs would increase, while the quality and quantity of work would decline. They also forecast increases in drug testing, performance monitoring, and education and rehabilitation programs as a result.     

The causes and consequences of land use regulation: Evidence from Greater Boston

Over the past 30 years, eastern Massachusetts has seen a remarkable combination of rising home prices and declining supply of new homes, which doesn't appear to reflect any lack of land. In this paper, we examine the increasing number of land-use regulations in Greater Boston. These regulations vary widely over space, and are hard to predict with any variables other than historical density levels. Minimum lot size and other land use controls are associated with reductions in new construction activity. These regulations are associated with higher prices when we do not control for contemporary density and demographics, but not when we add these contemporaneous controls. These results are compatible with economic theory, which predicts that production restraints on a good won't increase the price of that good relative to sufficiently close substitutes. Current density levels appear to be too low to maximize local land values.     

Macroeconomic effects of the regional allocation of public capital formation

This paper proposes a multi-regional, general equilibrium model with capital accumulation to analyze the economic impact of the spatial distribution of public capital formation. This model is calibrated and solved by using data for the Spanish economy in order to simulate some comparative dynamic exercises of fiscal policy changes. These analyses illustrate the role that public investment plays in generating the existing imbalances in regional development. This is done by computing the spillover effects and the opportunity costs of regional distribution of public investment. Finally, two rankings of regional priorities in public investment can be derived: one based on the criterion of reducing regional disparities, and another based on an efficiency criterion.     

论人民币汇率形成机制与资本账户开放

汇率形成机制与资本管理程度是开放经济最重要的两个政策安排。世界各国推进资本账户开放的动因各不相同,其中最主要的是通过资本的跨国界自由流动提高资源的配置效率。但是,近年来新兴市场国家(部分起因于资本流动过快)频繁发生的金融危机告诫我们对资本账户开放应持更谨慎的态度,而且汇率机制与资本账户管理程度必须密切配合,彼此协调,才能避免国际收支的严重失衡。文章通过阐述汇率安排与资本账户开放的关系,指出中国应循序渐进地放松资本管制和开放资本账户,逐步增大汇率制度弹性空间,最终实现资本账户开放和有管理的浮动汇率制度。     

Social Security and elderly labor supply: Evidence from the Health and Retirement Study

This study uses panel data from the Health and Retirement Study (HRS) to estimate the effects of Social Security income on elderly labor supply in the 1990s and early 2000s. The identification strategy takes advantage of the 1977 amendments to the Social Security Act, which led to a large, unanticipated reduction in Social Security benefits for those born after January 1, 1917. Despite the advanced age of the notch cohorts, there is a significant, negative and surprisingly elastic relationship between Social Security income and hours of work. This suggests that currently proposed reductions in benefits would induce Social Security recipients to work more hours in retirement, even through their 70s and early 80s.     

Adverse workplace conditions, high-involvement work practices and labor turnover: Evidence from Danish linked employer-employee data

Using Danish linked employer-employee data, we find that: (i) exposing the worker to physical hazards leads to a 3 percentage point increase in the probability of voluntary turnover from the average rate of 18%; (ii) working in night shift results in an 11-percentage point hike; and (iii) having an unsupportive boss leads to a 6-percentage point jump. High involvement work practices are found to play a significant role in mitigating the adverse effects of workplace hazards. Finally, the worker under adverse workplace conditions is found to improve the 5-year odds of rectifying such workplace adversities by quitting the firm.
