A review of empirical research on dynamic competitive strategy

Beginning with Chandler's 1962 seminal work, researchers have emphasized that competitive strategy is not a static phenomenon, but rather a sequence of interconnected actions and reactions unfolding over time. This paper reviews the empirical research on dynamic competitive strategy published between 1986 and 2005 in nine leading strategic management journals. An integrated framework is used to showcase the research in terms of antecedents, strategic actions and outcomes. The literature review demonstrates that significant progress has been made in the field of dynamic competitive strategy, and yet that there are still many promising lines of inquiry for future theoretical and empirical research, particularly in the areas of strategic action timing and path dependency.     

In search for the ideal coopetition partner: an experimental study

Coopetition (collaboration between competitors) has the potential to provide major benefits or losses to participating firms. Entering a partnership with a competitor is a strategic decision with potential long-term consequences rendering the choice of partner of key importance. Existing research has investigated partner’s strategic attributes, but not how the inter-organizational factors between coopetiting firms affect partner selection and on which layers those effects occur. We use a vignette study for reducing this gap, representing the first experimental study on the field of coopetition research. The results from our study from 874 evaluations of potential coopetition partnerships by key informants from Austria, Germany, Liechtenstein and Switzerland offer insights into how the possible partner’s role, resource alignment and the planned activity affect partner selection. The findings suggest that the partner’s role in the markets—i.e. whether it is a direct or an indirect competitor—is critical in partner selection. The planned activity and resource configuration is also found to influence the evaluation of possible coopetition partners. Overall, the results of this first experimental study in coopetition research provide important implications to both theory and practice.     

Social Entrepreneurship: An exploratory citation analysis

Research on Social Entrepreneurship became a growing field of interest during the past decades. However, as the heterogeneity of investigated topics is rather large the purpose of this contribution is to provide an overview of the current state of research on Social Entrepreneurship. In doing so previous research is structured to identify major contributions and thereby key discussion lines within this field. Based on a bibliometric citation analysis of 129 core papers and 5,228 cited references, five topic clusters are identified within the field of Social Entrepreneurship: 1) Definitions and conceptual approaches, 2) Impetus, 3) Personality, 4) Impact and performance, and 5) Future research agenda. By reflecting the literature of each discussion line, a framework for the advancement of Social Entrepreneurship research is provided.     

Varying the number of bidders in the first-price sealed-bid auction: experimental evidence for the one-shot game

The paper reports experimental data on the behavior in the first-price sealed-bid auction for a varying number of bidders when values and bids are private information. This feedback-free design is proposed for the experimental test of the one-shot game situation. We consider both within-subjects and between-subjects variations. In line with the qualitative risk neutral Nash equilibrium prediction, the data show that bids increase in the number of bidders. However, in auctions involving a small number of bidders, average bids are above, and in auctions involving a larger number of bidders, average bids are below the risk neutral equilibrium prediction. The quartile analysis reveals that bidding behavior is not constant across the full value range for a given number of bidders. On the high value quartiles, however, the average bid–value ratio is not different from the risk neutral prediction. The behavior is different when the winning bid is revealed after each repetition.     

Die Legitimität von Finanzregimen

In this article we propose a financial regime typology that adds the role of cultural legitimacy to financial market regulation. Bridging Comparative Political Economy and Economic Sociology we refer to a German Weberian tradition of institutionalist research that has stressed the intermediate position of institutions between social values and concrete market action. Financial regimes do not only define formal rules and organizational patterns, they also install symbolic boundaries between legitimate and illegitimate finance, providing cultural acceptance to these morally and historically “problematic” markets. The article then explores four fields of institutional regulation of stock exchanges in Germany and UK since the 19th century: (1) the creation of an official arena, (2) rules of market access, (3) the legitimate trading goods and (4) rules for penalizing misconduct. We show that German financial regulation was integrative and wanted to protect the real economy by corporatively embedding finance and restrain harmful transactions. In contrast, British financial regulation was segmental and tried to protect the real economy by installing a socially exclusive club of traders governed by professional expertise and hierarchy. This new typification of financial regimes will help to understand the resilience of national financial regulatory patterns across crises and the obstacles to a transnational harmonization of rules. Political reform-making is tied to institutional principles of the past.     

Zur Rolle einer optimierten Verteilung von Sicherheiten im internen Risikomanagement

The experiences from the recent financial crises show that the estimation and control of credit risks in banks are of significant managerial and economic importance. In this setting, the internal risk management as well as corresponding legal policies put an emphasis primarily on the prognosis of future credit defaults, whereas the role and impact of collaterals only play a minor role. Against this background the paper at hand analyzes the optimized distribution of collaterals within the internal risk management of banks at first. Furthermore, we develop a new flexible allocation algorithm that exceeds the existing approaches concerning the optimization without giving up the rule of a conservative appraisal of credit risk.     

Screening for trauma exposure, and posttraumatic stress disorder and depression symptoms among mothers receiving child welfare preventive services

The role of parental trauma exposure and related mental health symptoms as risk factors for child maltreatment for parents involved with the child welfare (CW) system has received limited attention. In particular, little is known about the extent to which mothers receiving CW services to prevent maltreatment have experienced trauma and suffered trauma-related psychopathology. This study examined screening data collected from 127 mothers receiving CW preventive services. There were high levels of trauma exposure among screened mothers and their young children. Among mothers, 91.6% experienced at least one traumatic event (M = 2.60) and 92.2% reported their children had been exposed to one or more traumas (M = 4.85). Mothers reported high levels of trauma-related symptoms: 54.3% met probable criteria for posttraumatic stress disorder (PTSD) or depression (61.7%). Nearly half (48.8%) met criteria for co-morbid PTSD and depression. The large majority of the clients with trauma-related disorders were not receiving mental health services. Latina women had significantly more severe PTSD symptoms than African American women. Case planners reported that the screening process was useful and feasible. These findings underscore the feasibility and importance of trauma screening among parents receiving CW preventive services.
