Diffusion of environmental business practices: A network approach

The purpose of this research is to build a conceptual foundation that examines network effects on the diffusion of environmental business practices (EBP) among suppliers. This research extends a network perspective to adoption of an environmental business practice across a large network of suppliers. The context of EBP is used to better understand adoption of a complex business practice, with perceived costs that are often greater than the perceived benefit. Variation in the level of structural and relationship embeddedness affect network diffusion of environmental business practices differently. Increased levels of structural and relational embeddedness are proposed to be positively associated with diffusion of EBP. From a practical standpoint, firms that leverage embeddedness may facilitate higher diffusion and adoption of environmental business practices. This facilitation may lead network actors to engage in EBP, and leverage benefits that may stem from these practices. This research introduces the concept of embeddedness to the environmental supply chain literature. Practicing managers can use the findings in this research to better position themselves within a network to diffuse EBP. This research also helps managers understand how supply chain members that are weakly connected to the primary network are important for introducing new ideas and innovations.

Resource Allocation in Higher Education in The Context of New Public Management

Abstract

The public administration framework New Public Management (NPM) has been applied to higher education systems in many western countries. The literature on these reforms reports on some positive effects but many critical voices can also be found. Even though NPM as a narrative unifies principles and measures under one roof, a detailed analysis shows that NPM principles fit differently for different tasks. Using a contingency approach, we show that, within the NPM narrative, two different higher education funding approaches exist, namely high-tech versus high-touch. Our study confirms the theoretical proposition that high-touch approaches match better with higher education domains. The use of contingency theory to classify NPM measures thus might be a promising way to further advance NPM theory and its practical application to topics as controversial as academic funding.     

Limits to the Implementation of Benchmarking Through KPIs in UK Construction Policy: Insights from game theory

Abstract

Benchmarking through the use of key performance indicators (KPIs) has been an important part of the UK government's market-oriented reforms to improve efficiency across the public sector and in other areas such as construction where government is a major client. However, government attempts to implement construction KPIs have not followed the expected course. We argue that insights from game theory show that the initial plan for construction benchmarking failed to take account of the strategic value of the information collected and was not implementable because the sharing of information by construction suppliers with their clients was a dominated strategy.     

Research on e-commerce transaction networks using multi-agent modelling and open application programming interface

We provide a formal definition of an e-commerce transaction network. Agent-based modelling is used to simulate e-commerce transaction networks. For real-world analysis, we studied the open application programming interfaces (APIs) from eBay and Taobao e-commerce websites and captured real transaction data. Pajek is used to visualise the agent relationships in the transaction network. We derived one-mode networks from the transaction network and analysed them using degree and betweenness centrality. Integrating multi-agent modelling, open APIs and social network analysis, we propose a new way to study large-scale e-commerce systems.     

Turning Agents into Psychological Principals: Aligning Interests of Non‐Owners through Psychological Ownership

Principals who delegate tasks to agents face the perennial challenge of overcoming agency problems. We investigate whether feelings of ownership among senior managers in the absence of formal ownership can align agents' interests with those of principals, thus turning agents into psychological principals. Using a moderated mediation model, we find that psychological ownership is positively related to company performance through the mediating effect of individual‐level entrepreneurial behaviour. We also find that the effect of psychological ownership on individual‐level entrepreneurial behaviour and, ultimately, company performance is weaker for high levels of monitoring compared to low levels. These findings offer important contributions to agency, psychological ownership, and entrepreneurship literatures.     

The relationship between private investors and small firms: an agency theory approach

Many small firms in Sweden are characterized by a lack of equity capital. For several years measures to increase the equity capital have been discussed. In this discussion the private investors' market has received virtually no attention. This study presents some preliminary results of the private investors in Sweden.

The research in small firms financing is characterized by a lack of theoretical framework. One basic assumption in the study is that agency theory can provide an essential framework to explain the interaction between the private investor and entrepreneur. Twenty-five hypotheses generated from agency theory are formulated and tested on 62 small unlisted firms in Sweden. Multiple regression analysis is used for the causal analyses.

The empirical results in the study show inter alia that the geographic distance and the private investor's knowledge about the portfolio firm's transformation process seem to be the most influential factors for determining the private investor's involvement in the portfolio firms. It is also interesting to notice that none of the variables, frequency of contacts and the private investor's operational work in the portfolio firm affect the performance of the firm. Contrary to conventional wisdom, private investors do not add value to their portfolio firms through their interaction with the entrepreneurs.

The theoretical conclusion is that agency theory does not provide any satisfactory framework to explain the private investor - entrepreneur relationship. Some of the basic assumptions in agency theory seem to be invalid. A model for the relationship between private investors and entrepreneurs is developed in which four interaction strategies are identified. The model gives implications on two levels: the portfolio level and the individual case level.     

Ethnic homophily perceptions as an emergent IHRM challenge: evidence from firms operating in Sri Lanka during the ethnic conflict

Ethnic conflict is a defining characteristic of the post-Cold War era and is prevalent particularly in emerging economies, areas of increasing interest to multinational enterprises. Yet little is known about the international human resource management challenges arising from such societal context. Utilizing social identity theory, we propose that ethnic homophily perceptions in the workplace – an employee's assessment that colleagues prefer working with ethnically similar others – is a reflection of the societal context and can be detrimental to the organization if not managed appropriately. We investigate whether contact theory offers insights to manage such perceptions. Drawing on a sample of 550 managers in Sri Lanka during a period of protracted ethnic conflict, we found that employee sensitivity to ethnic conflict in the societal context is positively related to ethnic homophily perceptions in the workplace, and that both ethnic diversity in workgroups and quality of work relationships serve to reduce perceptions of ethnic homophily.
