Network Embeddedness and the Exploration of Novel Technologies: Technological Distance, Betweenness Centrality and Density

Abstract: In this paper we analyze the innovative performance of alliance networks as a function of the technological distance between partners, a firm's network position (centrality) and total network density. We study how these three elements of an alliance network, apart and in combination, affect the 'twin tasks' in exploration, namely novelty creation on the one hand and its efficient absorption on the other hand. For an empirical test, we study technology-based alliance networks in the pharmaceutical, chemical and automotive industry.

Venture capital financing, moral hazard, and learning

Abstract: We consider the provision of venture capital in a dynamic agency model. The value of the venture project is initially uncertain and more information arrives by developing the project. The allocation of the funds and the learning process are subject to moral hazard. The optimal contract is a time-varying share contract which provides intertemporal risk-sharing between venture capitalist and entrepreneur. The share of the entrepreneur reflects the value of a real option. The option itself is based on the control of the funds. The dynamic agency costs may be high and lead to an inefficient early stopping of the project. A positive liquidation value explains the adoption of strip financing or convertible securities. Finally, relationship financing, including monitoring and the occasional replacement of the management improves the efficiency of the financial contracting.

The Compulsive Internet Use Scale (CIUS): Some Psychometric Properties

Abstract: The present study aimed to develop a short, easily administered, psychometrically sound, and valid instrument to assess the severity of compulsive Internet use. A set of criteria was determined based on the addiction literature. Next, the internal consistency and convergent validity were determined, and the set was tested as a one-factor solution in two representative samples of heavy Internet users (n = 447 and n = 229) and in one large convenience sample of regular Internet users (n = 16,925). In these three studies, respondents were asked about their online behavior and about problems related to Internet use. In the first study, the Online Cognition Scale (OCS) was included to determine concurrent validity. The newly developed Compulsive Internet Use Scale (CIUS) contains 14 items ratable on a 5-point Likert scale. The instrument showed good factorial stability across time and across different samples and subsamples. The internal consistency is high, and high correlations with concurrent and c...

The role of national culture in international marketing research

Abstract: Reviews and discusses the role of national culture in international marketing research. Special emphasis is given to national cultural frameworks. The two main national cultural frameworks – the Hofstede and the Schwartz – are discussed. Their interrelations are examined and four comprehensive national‐cultural dimensions are derived – autonomy versus collectivism, egalitarianism versus hierarchy, mastery versus nurturance, and uncertainty avoidance. The usefulness of national culture as an analytical basis in international marketing research is discussed and the construct of national culture is placed in the context of layers of culture, ranging from global cultures to micro cultures. Acculturation processes to other national cultures and antecedents of national culture are examined. The paper ends with concluding remarks and suggestions for future research.

Proximity and inter-organizational collaboration : A literature review

Abstract: The proximity concept is used in many different ways in the literature. These dimensions of proximity are, however, defined and measured in many different (sometimes even contradictory) ways, show large amounts of overlap, and often are under- or over-specified. The goal of this paper is to specify the different dimensions of proximity relevant in inter-organizational collaboration more precisely and to provide definitions of these dimensions. The research presented contributes to reducing the ambiguity of the proximity concept as used in the literature. Based on the above, the following research question is addressed in this paper: ‘Which dimensions of proximity are relevant in inter-organizational collaboration and how are they defined?’ A systematic literature review is presented in order to disentangle the dimensions of the proximity concept. Based on this literature review, three dimensions of proximity relevant in inter-organizational collaboration are distinguished: geographical proximity, organizational proximity and technological proximity. Examples (case studies) from the literature are used to illustrate the current conceptual ambiguity as well as to clarify how the proposed dimensions of proximity reduce this conceptual ambiguity.
