Approaches to the Ex-ante Evaluation of Investments into Information Systems

Sascha G. Walter; Thorsten Spitta

This paper critically reviews approaches for the evaluation of investments in information systems prior to their implementation. First, the ground for the review is prepared by examining characteristics of evaluation, information systems and value. A classification of the numerous evaluation approaches identified in English and German literature is then presented. Examples of each class are reviewed and their advantages and drawbacks are discussed. Their use in evaluation practice is analyzed through the examination of empirical studies and directions for future research are given.

University Departments and Self-Employment Intentions of Business Students: A Cross-Level Analysis

Sascha G. Walter; K. Praveen Parboteeah; Achim Walter

This study examines how characteristics of university departments impact students’ self–employment intentions. We argue that four organizational–level factors (entrepreneurship education, entrepreneurship support programs, industry ties, and research orientation) increase such intentions. Using a data set of 1530 business students and 132 professors at 25 university departments, this study shows that entrepreneurship education and industry ties are related to self–employment intentions only for the males in our sample. A negative effect of the departments research orientation was found. Our study suggests that the organizational context plays an important but gender–specific role in shaping future entrepreneurs. Implications of our findings are discussed.

Business Takeover or New Venture? Individual and environmental determinants from a cross-country study.

Jorn H. Block; Roy Thurik; Peter van der Zwan; Sascha G. Walter

Whereas the determinants of entrepreneurial choice have been thoroughly analyzed in the literature, little is known about the preferred mode of entry into entrepreneurship, such as taking over an existing business or starting a new venture. Using a large international data set, this study reports considerable differences in takeover preferences across 33 countries. Hierarchical (multilevel) regressions are performed to explore individual–level and country–level determinants of the preferred mode of entry. At the individual level, a persons human capital, risk attitude, and inventiveness influence the preference for starting a new venture versus taking over an existing business. At the country level, the culture–inherent level of risk tolerance, the countrys level of innovation output, and the administrative difficulty of starting a new business are found to explain the between–country variation in the preferred mode of entry. Implications of our findings for research and practice are also discussed.

Why mode and regional context matter for entrepreneurship education

Sascha G. Walter; Dirk Dohse

This study examines how modes of entrepreneurship education (active, such as business simulations, versus reflective, such as theory lectures) – alone and in interaction with the universities’ regional context – affect students’ self-employment intentions. Results from a cross-level analysis show that active modes are, irrespective of the regional context, positively related with intentions and attitudes towards entrepreneurship, whereas the effect of reflective modes is contingent on the regional context. The findings have important implications for the ongoing discussion on the teachability of entrepreneurship, the design of educational programmes and for future research.

Who becomes an entrepreneur? A 30-years-review of individual-level research

Sascha G. Walter; Simon Heinrichs

This article reviews the theoretical background and cumulates findings of 126 published studies (1980 - 2009) on individual determinants of entrepreneurial status. We categorize determinants into one of six paradigms (trait, cognitive, affective, intentions, learning, and economic) and review findings for 46 repeatedly studied variables. We then examine trends in the field and propose an agenda for future research. Our article complements prior reviews and meta-analyses by picturing the breadth of the field and adding important points to the research agenda.

Deutsche Universitäten als Gründungsinkubatoren : der Beitrag der Gründungsausbildung zur Gründungsintention von Studierenden

Sascha G. Walter; Achim Walter

ZusammenfassungEin steigendes Angebot universitärer Gründungsausbildung zielt darauf ab, studierende für eine unternehmerische Tätigkeit zu sensibilisieren und auszubilden und so die Anzahl akademischer Gründungen langfristig zu steigern. Zur prinzipiellen Effektivität derartiger Angebote liegen jedoch bisher kaum Erkenntnisse vor. Wir untersuchen, ob universitäre Gründungsausbildung nach einer Kontrolle personenbezogener Einflüsse überhaupt zur Entwicklung studentischer Gründungsintentionen beiträgt. Auf Basis einer deutschlandweiten Befragung von 2.621 studierenden an 63 universitären Fachbereichen zeigen Hierarchisch Lineare Regressionsmodelle, dass nur von anwendungsorientierter Gründungsausbildung handlungsrelevante Impulse ausgehen und diese Effekte auf Männer beschränkt sind. Weitere Geschlechterunterschiede bestehen in der Wirkung personenbezogener Einflüsse.SummaryUniversities increasingly offer entrepreneurship education, in order to sensitize and qualify students for entrepreneurship as a career option and, ultimately, to raise the number of academic start-ups. However, to date we have relatively little evidence on the effectiveness of such offers. Drawing on data from 2.621 students at 63 university departments in Germany, we examine the influence of university entrepreneurship education on students’ entrepreneurial intentions, after controlling for individual influences. Hierarchical linear regressions reveal that only active modes of entrepreneurship education are effective and that this effect is limited to men. Similarly, individual influences differ for women and men.

Personenbezogene Determinanten von Unternehmensgründungen: Stand der Forschung und Perspektiven des Fortschritts

Sascha G. Walter; Achim Walter

ZusammenfassungDieser Beitrag präsentiert den Status Quo der theoretischen und empirischen Forschung zu personenbezogenen Determinanten einer Unternehmensgründung. Eine Synopse von 99 großzahligen, empirischen Studien zeigt konsistente Befunde für 33 von 43 Determinanten. Sie sind theoretisch vor allem in der dispositiven, verhaltensorientierten und ökonomischen Perspektive verwurzelt, während kaum Untersuchungen aus der kognitiven und netzwerkorientierten Perspektive vorliegen. Weiteren Fortschritt versprechen insbesondere Beiträge, die mehrere Perspektiven integrieren, zwischen Existenz- und Unternehmensgründungen unterscheiden und den Kontext im Rahmen von Mehrebenenanalysen stärker berücksichtigen.SummaryThis paper reviews the status quo of theoretical and empirical research on individual-level determinants of founding decisions. A synopsis of 99 quantitative studies reveals consistent findings for 33 of 43 determinants. Most studies are theoretically grounded in dispositive, behavioral, or economic research, whereas few studies cover the cognitive or network-oriented perspective. In order to further advance the field, we would suggest to integrate theoretical perspectives, to explicitly distinguish small business owners from entrepreneurs, and to acknowledge higher-level influences by conducting cross-level research in future studies.

Unternehmensgründung und Funktionen von Netzwerkbeziehungen

Sascha G. Walter; Achim Walter

In den letzten Jahren hat die Netzwerkperspektive verstarkt Einzug in die Designs vieler Studien im Bereich Entrepreneurship gefunden. Ziel dieses Beitrags ist es, die Vielfalt dieser Arbeiten ubersichtsartig darzustellen und kritisch zu wurdigen sowie Losungsvorschlage fur einige Probleme des Netzwerkansatzes zu skizzieren. Die Auswertung von insgesamt 20 Studien zeigt eine Dominanz von Untersuchungen des Grundungserfolgs und der Ressourcenbeschaffung in der Nachgrundungsphase. Oft wird in den Untersuchungen nicht deutlich, (a) ob Leistungen zwischen den Beziehungspartnern uberhaupt fliesen und (b) ob bzw. inwiefern entsprechende Leistungen einen Einfluss auf die jeweiligen abhangigen Variablen haben. Eine Modellierungsstrategie auf Basis von Beziehungsfunktionen, die entweder als Klassifikationskriterium oder als konkrete Modellkomponenten verwandt werden, stellt eine mogliche Losung dieser Probleme dar.

Dysfunktionen in F&E-Koopetitionen : Präventivmaßnahmen und Kooperationserfolg

Sascha G. Walter; Dirk Müller; Achim Walter

Collaborating with competitors (coopetitions) in the field of R&D is highly advantageous and risky at the same time. This study examines (1) how firms can protect themselves against the negative consequences (dysfunctions) of coopetitions and (2) how dysfunctions affect coopetition success, defined as relationship value and satisfaction with the partner performance. Results show that goal alignment and contractual safeguards decrease unintended knowledge leakages, which are positively related to the degree of formalization. Only goal alignment discourages strategic manipulation. Strategic manipulation rather than unintended knowledge leakages diminishes the success of a coopetition. Our findings have important implications for future research on and the practical management of R&D coopetitions.ZusammenfassungKooperationen mit Wettbewerbern (Koopetitionen) zählen zu den potenzialreichsten, aber auch riskantesten Formen von F&E-Kooperationen. Dieser Beitrag untersucht, inwiefern sich Unternehmen schon in der Anbahnungsphase vor negativen Konsequenzen derartiger Partnerschaften, so genannten Dysfunktionen, schützen können und wie sich Dysfunktionen gegebenenfalls auf den Kooperationserfolg, gemessen am Beziehungswert und der Zufriedenheit mit den Partnerleistungen, auswirken. Unseren Befunden zufolge vermindern Zielfit und Schutzvereinbarungen den ungewollten Abfluss wichtigen Wissens, der jedoch überraschenderweise durch Formalisierung verstärkt wird. Nur Zielfit wirkt einer strategischen Manipulation durch den Partner entgegen. Strategische Manipulation, nicht jedoch ein unintendierter Wissensabfluss beeinträchtigen den Kooperationserfolg. Unsere Befunde besitzen wichtige Implikationen für die zukünftige Forschung und das praktische Management von F&E-Koopetitionen.

Radicalness of Technological Inventions and Young Venture Performance—The Role of Technological Competition and Product Diversity

Arne Schmidt; Sascha G. Walter; Achim Walter

Opportunities often emerge in the form of technological inventions that offer ways to create or deliver new value to prospective customers across a broad range of industries. This study investigates how the radicalness of technological inventions is tied to performance (sales growth) in young technology-based ventures. Using a combination of survey and patent data from 85 spin-offs from public research institutions in Germany, we identify the degree of technological competition and product diversification as important moderators in the relationship between technological radicalness and venture performance. Radicalness is found to have a positive impact on sales growth when competition in the particular technology field is high and when the ventures product portfolio is not diversified. Overall, these findings contribute to a better understanding of when and how ventures can successfully exploit radical technological inventions.
