  • The Tangled Nature Model for organizational ecology
    • Authors: Rudy Arthur; Arwen Nicholson; Paolo Sibani; Michael Christensen
      Pages: 1 - 31
      Abstract: Abstract The Tangled Nature Model—a biologically inspired model of evolutionary ecology—is described, simulated, and analyzed to show its applicability in organization science and organizational ecology. It serves as a conceptual framework for understanding the dynamics in populations of organizations. A salient dynamical feature of this model is the spontaneous generation of a symbiotic group of core organizations. This core, consisting of several dominating species, introduces a mesoscopic level between that of the individual and the whole system. Despite prolonged periods of stability, this core is disrupted at random by parasitic interactions causing sudden core rearrangements. The size distribution of the core organizations is log-normal as predicted by theory and supported by empirical findings. As a simple application of the model, we study the adaptation of organizations to changes in resource availability in terms of population size, population diversity, and ecological efficiency. We find evidence that a temporary reduction in resources forces a consolidation resulting in a sustained increase in overall efficiency, suggesting that such reductions can be applied strategically to drive incremental improvements.

  • Effects of asymmetric knowledge spillovers on the stability of horizontal
           and vertical R&D cooperation
    • Authors: Deming Zeng; Luyun Xu; Xia-an Bi
      Pages: 32 - 60
      Abstract: Abstract In order to investigate the role of asymmetric spillovers in the stability of R&D cooperation, this paper distinguishes two different types of cooperative partners, and uses a game theory approach to reveal the relationship between asymmetric spillovers and R&D investment in the horizontally and vertically related R&D cooperation. In the horizontal R&D cooperation, higher incoming spillovers and lower outgoing spillovers induce firms to invest on R&D efforts as agreed. However, it is the contradiction between horizontal firms’ attitudes towards asymmetric spillovers that leads to the inherent instability of the cooperation. In the vertical R&D cooperation, our results question the usually held opinion about the effects of asymmetric spillovers on the decision of R&D investment. The incoming spillovers are less important in the innovation process for vertically related R&D cooperation. A firm tends to under-invest on the arranged level of R&D efforts when its incoming spillovers increase. Our results also show that efficient mechanisms to restrain firms’ non-cooperative behavior are essential to improve the stability of horizontal and vertical R&D cooperation.

  • Inferring final organizational outcomes from intermediate outcomes of
           exploration and exploitation: the complexity link
    • Authors: Sasanka Sekhar Chanda
      Pages: 61 - 93
      Abstract: Abstract The difficulty in definitively linking outcomes of managerial action to organizational outcomes has been a festering issue in organizational research. The problem arises because it is not easy to separate the distinctive contributions of managers at intermediate stages, as well as the contribution of external factors beyond the control of managers. Specifically, certain managerial actions focusing on exploratory or exploitative innovation produce an intermediate output, organizational knowledge. From this base of organizational knowledge, further management actions craft the final output that eventually faces the market test. Drawing from complexity concepts, I argue that the probability of correctly fashioning the subset of key elements in the intermediate output may be a good measure of the probability of organizational success. I use March’s iconic computational simulation model to demonstrate the merits of this principle. I model the effect of complexity on managerial intentionality towards exploratory and exploitative innovation. I elicit important insights for research and practice by comparing organizational knowledge outcomes with the outcomes for probability of organizational success, in stable and moderately turbulent environment.

  • Controlling for false negatives in agent-based models: a review of power
           analysis in organizational research
    • Authors: Davide Secchi; Raffaello Seri
      Pages: 94 - 121
      Abstract: Abstract This article is concerned with the study of statistical power in agent-based modeling (ABM). After an overview of classic statistics theory on how to interpret Type-II error (whose occurrence is also referred to as a false negative) and power, the manuscript presents a study on ABM simulation articles published in management journals and other outlets likely to publish management and organizational research. Findings show that most studies are underpowered, with some being overpowered. After discussing the risks of under- and overpower, we present two formulas to approximate the number of simulation runs to reach an appropriate level of power. The study concludes with the importance for organizational behavior scholars to perform their models in an attempt to reach a power of 0.95 or higher at the 0.01 significance level.

  • Modeling the governance of cooperative firms
    • Authors: Harold Paredes-Frigolett; Pablo Nachar-Calderón; Carmen Marcuello
      Pages: 122 - 166
      Abstract: Abstract Most studies of cooperative firms have been conducted using neoclassically inspired economic models that consider the characteristics and behavior of capitalist companies and their owners, thus failing to accommodate the wide range of criteria that motivate the creation of cooperative firms. These models have traditionally been at odds with the real objectives of cooperative firms due to their inability to accommodate a series of often conflicting criteria. We put forth a set-theoretic model of governance of cooperative firms that allows us to investigate how different models of cooperative governance can be implemented and how cooperative decision-making can be solved using a multicriteria decision analysis approach.

  • Explaining the emergence of online popularity through a model of
           information diffusion
    • Authors: António Fonseca; Jorge Louçã
      Abstract: Abstract This paper proposes a new formal modeling approach to popularity dynamics based on a generic notion of message propagation within society. The approach is demonstrated with two original models of information diffusion. These are a branching model of popularity and a epidemic model of popularity. The first is based on the principles of a branching process, while the second emulates an epidemic equation with a specific infection rate. This allows us to consider the replication phenomena on information diffusion. The approach is validated using a very large dataset collected online that involves keywords in blogs and hashtags on Twitter. Our main results point to an overall good fit of both models, both when the process of popularity grows and when it decays. This is due to endogenous information transfer, as in an epidemic process, but also when the process is initially triggered by an external event. Overall, on balance, our models confirm that popularity builds through message diffusion, which is of the multiplicative kind.

  • Blockmap: an interactive visualization tool for big-data networks
    • Authors: Terrill L. Frantz
      Abstract: Abstract This article describes the Blockmap, which is a mechanism for displaying and exploring network datasets. The data are presented in a squarified-mosaic form, which is well-suited for visual display on a computer or phone screen. The relational data are dimension-reduced and structured for interactive, hierarchical exploration. The Blockmap applies a combination of treemap and heatmap display schemes specifically to the analysis of large network datasets. The Blockmap offers the analyst a way to explore underlying node-level data, at the full-network level, according to shared characteristics of the constituent nodes. It offers a technique for exploring nodesets—collections of network nodes—which have been classified according to a user-defined set of rules or discriminative algorithms. Typically, nodes can be classified according to their common attributes or a stratification of their ego-level network measures, but means can be extended. Using a Blockmap, an analyst can profile a network according to the meaningful characteristics exhibited by the mosaic; this technique also offers theorists a platform for developing a methodological and analytic framework for characterizing and analyzing network data. Production versions of Blockmap technology are presently hosted in client- and web-based software and is available freely in *ORA-LITE.

  • An agent based model of the evolution of supplier networks
    • Authors: David C. Earnest; Ian F. Wilkinson
      Abstract: Abstract We view supply chains as a type of complex adaptive system and develop an agent based computer simulation model of the evolution and performance of supply chains based on Stuart Kauffman’s NK models of fitness landscapes. Firms operate in networks in which they supply products to some firms and source inputs from others. They seek to maximize their own performance but they cooperate with other firms to gain access to inputs. We model firm performance in terms of the fit of its product with market demand and the contribution from first tier suppliers. The model uses genetic algorithms to mimic the way firms learn and adapt their products and supplier networks for more and less complex products and different switching conditions. We find that (a) as the complexity of the product increases, firms perform less well; and (b) firms build supplier networks with higher average in-degree, greater density, and significantly greater clustering to cope with product complexity. Our findings suggest that firms using highly specific assets or that face high switching costs are likely to pursue a supplier strategy that relies more on multiple suppliers and more clustered supply networks. Also, in industries characterized by highly specialized training, plants and machinery dedicated to specific products and other high product-specific transaction costs, we should observe more specialization at low levels of product complexity but less at high levels. The model contributes to our understanding of the evolution of supply networks, which is an under-researched topic, provides the basis for further extensions of the model and the development of more realistic models of actual supply chains. The model also provides a conceptual and methodological tool to assist firms and policymakers to better understanding the nature of supply chains and to identify and test strategies and policies.

  • A comprehensive approach in designing a sustainable closed-loop supply
           chain network using cross-docking operations
    • Authors: Saeid Rezaei; Amirsaman Kheirkhah
      Abstract: Abstract In today’s competitive world, it is unavoidable to provide a new efficient approach in the cycle of production and supplying. The problem of designing a supply chain network is included in strategic decisions in this area, and short-term changing the structure and configuration of logistics networks is almost impossible due to assigned much time and cost. This paper develops a comprehensive model for designing a sustainable closed-loop supply chain network based on economic, environmental and social requirements, both with applying cross-docking operations in the mentioned network. Utilizing the cross-docking system—as a new strategy of supply chain—along with simultaneous considering the above triple dimensions—economic, environmental and social requirements—in a comprehensive and sustainable approach offers a novel research scope in the wide range of problems related to supply chain network design, and in this regards, helps organizations improve their competitive advantage in different industries. For these reasons, in this study, a multi-objective mixed-integer linear programming model is developed, and in order to solve this NP-hard problem, a cuckoo optimization algorithm is utilized—as the first attempt in this area. Finally, to test the efficiency of the proposed metaheuristics, it is compared with other strong algorithms illustrating a quite well performance.

  • The meso-unit theory of post-merger integration
    • Authors: Terrill L. Frantz
      Abstract: Abstract This article introduces the meso-unit theory of post-merger integration. The theory offers that the number of constituent work-units involved in an organizational merger has a greater detrimental effect on the time-to-integration than does the total number of constituent personnel involved. Its establishment is based on the results of controlled experiments conducted in a virtual laboratory. The simulation utilizes agent-based modeling software that encapsulates organizational behavior models such as the knowledge-based view of the firm, social and communication network theory, and CONSTRUCT theory. The software is configured for a two-organization merger and implements classic behavior dynamics to simulate communicative behavior of information-seeking actors. As a result, detailed micro- and macro-level data on the integration progress is available for examination, analysis and interpretation. The results give rise to the development of the meso-unit theory, which directs integration managers’ attention toward a key aspect of the integration that is often overlooked.

  • Operations research methods in political decisions: a case study on the
           European Parliament composition
    • Authors: Janusz Łyko; Radosław Rudek
      Abstract: Abstract In this paper, we show that operations research methods can be successfully applied to support decision-making in politics on the case study of the apportionment of seats in the European Parliament. The related political constraints and assumptions are quantitatively described and the optimization problem is formulated. On this basis, it is revealed that the current composition of the European Parliament as well as some intuitive propositions do not respect degressive proportionality as far as it was assumed. Nevertheless, our algorithm allows us to find better solutions, and among them, there is only one best allocation, which respects degressive proportionality as far as possible, according to the well known and often applied measures. Namely, over 9 thousands allocations consistent with the political requirement “nobody gains and nobody loses more than one” are referred to over 5.4 millions degressively proportional solutions, and only one allocation is revealed to be the best for all defined criteria under given populations of countries.

This study intends to fill such gap and provides arguments on the effects of three different types of task assignment (exploration only, exploitation only, and both exploration and exploitation) on individual performance to understand ambidexterity. We adopted a single-agent simulation model and examined the relationship between the three types of task assignment and individual performance measured by the knowledge creation level. Individual attitude toward risk and tension between exploration and exploitation are considered in our simulation model. The findings suggest that the assignment of the ambidextrous task (both exploration and exploitation) generates the highest individual performance under some conditions, which negates the assumption that individuals find it difficult to handle both exploration and exploitation.

  • Collective action in organizational structures
    • Authors: Sergio F. Góngora y Moreno; J. Octavio Gutierrez-Garcia
      Abstract: Abstract Public goods games played by a group of individuals collectively performing actions towards a common interest characterize social dilemmas where both competition and cooperation are present. By using agent-based simulation, this paper investigates how collective action in the form of repeated n-person linear public goods games is affected when the interaction of individuals is driven by the underlying hierarchical structure of an organization. The proposed agent-based simulation model is based on generally known empirical findings about public goods games and takes into account that individuals may change their profiles from conditional cooperators to rational egoists or vice versa. To do so, a fuzzy logic system was designed to allow the cumulative modification of agents’ profiles in the presence of vague variables such as individuals’ attitude towards group pressure and/or their perception about the cooperation of others. From the simulation results, it can be concluded that collective action is affected by the structural characteristics of hierarchical organizations. The major findings are as follows: (1) Cooperation in organizational structures is fostered when there is a collegial model defining the structure of the punishment mechanisms employed by organizations. (2) Having multiple, and small organizational units fosters group pressure and highlights the positive perception about the cooperation of others, resulting in organizations achieving relatively high aggregate contribution levels. (3) The greater the number of levels, the higher the aggregate contribution level of an organization when effective sanctioning systems are introduced.

  • Integration decision-making in technology-sourcing cross-border
           M&As: a mathematical model
    • Authors: Feiqiong Chen; Yao Chen; Fangfang Zhong
      Abstract: Abstract Post-merger integration plays a key role in the success of mergers and acquisitions, but how to choose the appropriate integration mode to achieve potential synergies in mergers and acquisitions (M&As) still lacks widely accepted theoretical support and practical experience. Therefore, this article establishes a mathematical model considering the similarity and complementarity of resources in an attempt to explore the optimal integration strategy (including the choices of integration degree and autonomy granted to the target) under different conditions of resources similarity and complementarity, thus building a comprehensive framework that considers pre- and post-merger factors together to jointly explain innovation realization in technology-sourcing cross-border M&As. The results show that the higher the resource similarity, the higher the degree of integration and the lower the degree of target autonomy. Conversely, the higher the resource complementarity, the lower the degree of integration and the higher the degree of target autonomy. Resource similarity and resource complementarity have negative interactions for integration and target autonomy. The higher the resource similarity, the faster the convergence of optimal degree of integration, while the higher the resource complementarity, the slower the convergence. The study results add to our knowledge of M&A integration management, and provide some implication for practitioners.

  • Managerial influence on attitude formation in organizations: how to manage
    • Authors: Peter van Woensel; Dick de Gilder; Peter van den Besselaar; Peter Groenewegen
      Abstract: Abstract The emergence of a shared attitude in organizations can be regarded as a self-organizing complex process in which a majority attitude emerges from the ensemble of interactions among individuals. Almost by definition, emerging processes seem beyond the control of management, which is in conflict with the task of management to steer an organization. By modeling the emergence of a shared attitude in organizations, we were able to demonstrate that management had a distinct influence on this process. Furthermore, the first round of interactions was decisive for the outcome. The key to influencing the emergence of a shared attitude is to reduce resistance against the preferred attitude. High levels of group conformity inhibited conversion to the preferred attitude. Although the emergence of a shared attitude can be influenced by management, there remains an intrinsic uncertainty in the outcomes of attitude development processes.
