    Market Partitioning and the Geometry of the Resource Space
    (1999) Péli Gábor; Nooteboom, Bart
    The paper gives a geometry based explanation for organization ecology’s resource partitioning theory. The original theory explains market histories of generalist and specialist organizations with scale economies. We show that the main predictions can be restated in terms of certain structural properties of the n-dimensional Euclidean resource space. We model customer demand elaboration with the increasing number of dimensions (taste descriptors), and demonstrate that the resulting change in spatial configurations increases market concentration and enhances resource partitioning. The original and the proposed models of resource partitioning are complementary: their predicted effects add up and drive the events towards the perceived market phases. Moreover, each approach answers questions that the other cannot address.

    Reasoning with partial knowledge
    (2002) Pólos László
    We investigate how sociological argumentation differs from classical first-order logic. We focus on theories about age dependence of organizational mortality. The overall pattern of argument does not comply with the classical monotonicity principle: Adding premises overturns conclusions in an argument. The cause of nonmonotonicity is the need to derive conclusions from partial knowledge. We identify metaprinciples that appear to guide the observed sociological argumentation patterns, and we formalize a semantics to represent them. This semantics yields a new kind of logical consequence relation. We demonstrate that this new logic can reproduce the results of informal sociological theorizing and lead to new insights. It allows us to unify existing theory fragments, and it paves the way toward a complete classical theory. Observed inferential patterns which seem “wrong” according to one notion of inference might just as well signal that the speaker is engaged in correct execution of another style of reasoning. —Johan van Benthem (1996)

    Logics of organization theory: audiences, codes, and ecologies
    (Princeton University Press, 2007) Pólos László
    Building theories of organizations is challenging: theories are partial and “folk” categories are fuzzy. The commonly used tools—first-order logic and its foundational set theory—are ill-suited for handling these complications. Here, three leading authorities rethink organization theory. Logics of Organization Theory sets forth and applies a new language for theory building based on a nonmonotonic logic and fuzzy set theory. In doing so, not only does it mark a major advance in organizational theory, but it also draws lessons for theory building elsewhere in the social sciences. Organizational research typically analyzes organizations in categories such as “bank,” “hospital,” or “university.” These categories have been treated as crisp analytical constructs designed by researchers. But sociologists increasingly view categories as constructed by audiences. This book builds on cognitive psychology and anthropology to develop an audience-based theory of organizational categories. It applies this framework and the new language of theory building to organizational ecology. It reconstructs and integrates four central theory fragments, and in so doing reveals unexpected connections and new insights.

    Organizational decision-maker bias supports merger wave formation: demonstration with logical formalization
    (2015) Péli Gábor; Schenk, Hans
    Imitation of firms that opt for strategic reorganizations by opting for mergers and acquisitions facilitates market wave formation. Empirical evidence on mergers and acquisitions suggests that, under uncertainty, firms regret more not following their rivals’ merger moves of yet unknown outcome than possibly failing jointly by copying them. Looking for the rationale for this bandwagon behavior, we explore the underlying decision-making framework by using formal logic and search for behavioral premises consistent with the observed outcomes. We point out three biased expectations, modeled by using a belief modal operator, that filter out relevant scenarios from the consideration set of otherwise rationally behaving decision-makers. The theorems derived from the logic model highlight the drive to imitate competitors’ merger choices for all but one of the eight possible outcomes of the decision-making framework. For the latter case, a boundary condition is given that makes imitation the predicted strategy. Our approach goes against the view that human behavior defies logic-based rendering also if such behavior can be adequately described as non-rational in an economic sense. Logic is a flexible representation tool to model even faulty behavior patterns in a transparent way; it can also help exploring the consequences of the cognitive mistakes made. Our findings suggest that threats to wealth creation may not necessarily find their origins in morally questionable organizational behavior, but rather in modalities of decision-making under uncertainty.

    Using learning management systems in business and economics studies in Hungarian higher education
    (2016) Fiamné Dr. T.Nagy Judit
    This paper explores all uses of LMS in teaching Business Mathematics in Hungarian undergraduate training from the point of view of the instructors. Since no similar survey had been carried out in Hungary earlier, the aim was to fill in this gap and to investigate which LMS systems are being used by the instructors, to what specific purposes and how intensively. The importance of this study is that it highlights the local correlations and shortcomings thus making the adoption of LMS systems in Business Mathematics more effective. The survey was carried out by using questionnaires compiled by the author (survey method). All the institutions of Business Mathematics were questioned, one instructor in each (N=28), so the data survey was comprehensive. The results of the article show that the proportion of instructors using LMS systems in undergraduate Business Mathematics training is lower than might be expected from the literature. Correlations have been demonstrated (elements characteristic of the country) with which the phenomena can be explained. This study shows – consistent with other studies – that LMS was commonly used by instructors for textbased communication and for delivering text-based learning materials. Even special tools and activities supporting mathematics are used for such purposes in a small number of cases; solutions outside the scope of LMS are used in a larger proportion.
