We contribute to the literature on firms' responses to institutional pressures and environmental information disclosure. We hypothesize that CEO characteristics such as education and tenure will influence firms' likelihood to voluntarily disclose environmental information. We test our hypotheses by examining firms' responses to the Carbon Disclosure Project (CDP) and find that firms led by newly appointed CEOs and CEOs with MBA degrees are more likely to respond to the CDP, while those led by lawyers are less likely to respond. Our results have implications for research on strategic responses to institutional pressures and corporate environmental performance. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

This study examines and extends the resource dependence logic of diversification for a better understanding of outward foreign direct investment (OFDI) activities by emerging market firms. We contend that the diversification logic is bounded by state ownership, an important but less considered component of interdependence. Our empirical results, based on panel data analysis of Chinese listed firms, suggest that the level of interdependence between Chinese and foreign firms in China in multiple forms, including symbiotic, competitive, and partner interdependencies, is positively associated with the level of the Chinese firms' OFDI activities. However, Chinese firms with higher levels of state ownership are less susceptible to the pressures imposed by foreign firms to invest abroad. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

The literature on organizational learning asserts that external learning is often limited geographically and technologically. We scrutinize to what extent organizations acquire external knowledge by accessing external knowledge repositories. We argue that professional service firms (PSFs) grant access to nonlocalized knowledge repositories and thereby not only facilitate external learning but also help to overcome localization. Focusing on patent law firms, we test our predictions using a unique dataset of 544,820 pairs of European patent applications. Analyzing patterns of knowledge flows captured in patent citations, we find that accessing a PSF's repository facilitates the acquisition of external knowledge. As the effect is more pronounced for knowledge that is distant to a focal organization, we conclude that having access to a knowledge repository compensates for localization disadvantages.

This article examines the dynamics between mortgage broker competition, origination fees and price transparency. A reverse first‐price sealed‐bid auction model is used to motivate broker pricing behavior. Confirming the model predictions, our empirical analysis shows that increased mortgage brokerage competition at the Metropolitan Statistical Area level leads to lower fees. The findings are robust to different measures of fees as well as different measures of competition. We also provide evidence that broker competition reduces mortgage origination fees on retail (nonbrokered) loans as well. In addition, our results indicate that pricing complexity is an important determinant of fees, and increased broker competition is associated with a higher probability of a loan being priced with transparency. Our results suggest that mortgage brokers increase competition and lower fees in the mortgage market.  相似文献

This study seeks to explain the differential effects of workforce flexibility on incremental and major new product development (NPD). Drawing on the resource‐based theory of the firm, human resource management research, and innovation management literature, the authors distinguish two types of workforce flexibility, functional and numerical, and hypothesize differential effects on NPD outcomes. A large‐scale sample of 284 Dutch firms across various manufacturing goods and business services industries serves to test these hypotheses. The results suggest that functional flexibility positively influences incremental NPD only, internal numerical flexibility negatively influences incremental NPD only, and external numerical flexibility positively influences major NPD only. Thus, differences between major and incremental NPD are grounded in the human resource flexibility of the firm. This complements research that found that such differences lie in critical development activities, learning processes, and capabilities. It also complements product innovation research on flexibility in NPD processes and on flexibility in organizational structures and routines. It extends the resource‐based theory of the firm suggesting that human resource flexibility is part of the dynamic capabilities that allow firms to reconfigure existing competencies. The conclusions imply that managers of manufacturing and service firms may use training and education and create a functional flexible workforce that can progressively enhance incremental NPD outcomes. They may want to avoid paying overtime, because such internal numerical flexibility hampers incremental NPD, but use fixed‐term contracts to expand external numerical flexibility to enhance major NPD.  相似文献

Recent calls for using the antitrust laws to break up the large Internet giants are misplaced for a number of reasons. First, similar efforts against oil, tobacco, motion-picture, and telecommunications monopolies have not proved to be beneficial to economic welfare. Second, the failure to break up Microsoft using Section 2 has not proved to be a mistake: competition in operating systems and Internet browsers has flourished recently. Finally, a Section 2 case against Amazon, Facebook, or Google could not succeed if it focused on the digital advertising market. Even in a case based on market power on the other side of their platforms, a structural remedy—a break-up—would not improve economic welfare in the long run.

Severe socio-economic issues that threaten peace, life or wellbeing of humans in specific regions of the world cannot be solved by any single actor. Wide networks of political, business, governmental, non-profit and humanitarian organizations are to be involved to change existing practices. Despite conflicting interests and competing behavior, involved organizations need to act collectively to initiate the change of commonly accepted practices, i.e. institutions. This is the space in the present study for examining network mobilization as a collective means to change institutions. Our aim is to answer the question: How are networks mobilized in crisis management to initiate institutional change processes in socio-economically turbulent contexts? We provide a framework of network mobilization for institutional change built on the IMP rooted network mobilization research and institutional entrepreneurship discussion. The framework is reflected upon by means of insights from an interview-based case study with representatives of governmental and non-governmental organizations involved in worldwide humanitarian peace-building. We identify, firstly, incentivizing, reticent and adaptational behaviors of network mobilizers to utilize legitimacy and relationship sediments as mobilization enablers. Secondly, these behaviors help network mobilizers to overcome actor visibility and unpredictability as mobilization obstacles in turbulent contexts.  相似文献

This study examined how entry‐level employees interacted with social media during three stages of organizational socialization. They navigated between four different media affordances (persistence, editability, visibility, and association) while experiencing them as both enabling and constraining in different socialization stages. Qualitative interview data analysis revealed during anticipatory socialization, job applicants realized visibility and persistence in relation to institutional and individualized socialization. During encounter, new employees managed personal and professional life boundaries carefully against the association and visibility affordances. Although some participants used both public and enterprise social media for obtaining job‐related information and understanding coworkers and company culture, during metamorphosis, most interviewees adopted passive information seeking strategies and experienced a paradoxical tension between the enabling and constraining affordances of social media. Findings are discussed with regards to employees’ exertion of agency in managing their professional impressions and coping with high levels of uncertainty and vulnerability during early stages of socialization.  相似文献

This paper contributes to the very small empirical literature on the effects of competition on managerial incentive schemes. Based on a theoretical model that incorporates both strategic interaction between firms and a principal agent relationship, we analyse the relationship between product market competition, incentive schemes and firm valuation. The model predicts a nonlinear relationship between the intensity of product market competition and the strength of managerial incentives. We test the implications of our model empirically based on a unique and hand‐collected dataset comprising over 600 observations on 200 Swiss firms over the 2002–2005 period. Our results suggest that, consistent with the implications of our model, the relation between product market competition and managerial intensive schemes is convex indicating that above a certain level of intensity in product market competition, the marginal effect of competition on the strength of the incentive schemes increases in the level of competition. Moreover, competition is associated with lower firm values. These results are robust to accounting for a potential endogeneity of managerial incentives and firm value in a simultaneous equations framework.  相似文献
