Abstract:
Business research increasingly considers wicked problems and complex dynamic systems. Analytical models of such problems and systems quickly become untraceable and unsolvable. Given increasing computational power, simulation models provide an alternative tool. They can fuel studies tracing the long-term evolution of systems and comparing the outcomes of alternative scenarios. However, successfully applying simulation modelling for business research requires expertise on applicable simulation paradigms, approaches to model validation and the analysis of stochastic results.

Abstract:
This doctoral seminar exposes students to foundational and current research in organization theory. It specifically focuses on macro-organizational theory, derived largely from sociological and economic theoretical traditions. This type of organizational theory is interested in the interaction of organizational structures and processes with the wider political, economic, societal, or natural environment. Among others, it tries to explain the emergence of organizational forms and organizational survival, resource acquisition and utilization, interaction between organizations, the perception of organizations in society, or organizational responsibility. Instead of giving a comprehensive historical introduction into the “classics” of organization theory, this course will focus on current advancements of core theoretical concepts such as sensemaking, institutions, routines or networks as well as on more recent theoretical streams such as the ‘strong’ process view of organization or the communicative constitution of organization. Assessment will mainly be based on reading assignments and participation.

Abstract:

The course covers the basic elements of i) Markovian models of stochastic systems and ii) Markovian decision processes plus some basic elements of inventory theory. In this course, participants will learn how to construct and use these particular classes of probabilistic models of systems and decision processes. The defining feature of the Markovian models is the memoryless property of the underlying stochastic processes. It essentially states that the future behavior of a system depends only on its current state, but not its previous history. The participants will learn why and how this often makes it possible to determine the probabilities of the different system states and how these probabilities can then be used to determine performance measures of the system or to assign economic values to decisions made in an uncertain environment.

Content

We will start by describing the defining features and variants of stochastic processes, focusing on those processes with a discrete state space. We will initially cover Markovian processes in discrete time as their modeling and analysis happens to be straightforward, clear and illustrative. On this basis, we will then address Markovian processes in continuous time, the so-called Markov Chains. We will describe Poisson processes, the famous memoryless property of the exponential distribution and derive the necessary and sufficient balance equations for the steady-state analysis of Markov Chains in continuous time. The participants will install and use Scilab, an free and open-source software for numerical computation (www.scilab.org), on their machines to perform numerical experiments and solve small exercises.

Based on this foundation, we will then address the analysis of Markovian queuing systems and show how to determine the probability of having a given number of customers or jobs in the system or the queue. After introducing and explaining Little’s Law, we will use it to determine expected waiting or cycle times. Closing this introduction to queuing models, we will briefly explain and demonstrate Kingman’s approximation for the expected waiting time G/G/1 and G/G/N queueing model.

In the next section, we will briefly cover basic elements of the probabilistic analysis of inventory systems. We will introduce the classical newsvendor problem and use it to explain and apply the first order loss function for the case of normally distributed demand.

The next part of the course will be devoted to stochastic (dynamic) programming, also known as stochastic decision processes. Starting with a finite-horizon deterministic setting, we will treat the basic version of Bellman’s recursion equation and explain its usage to determine an optimal course of actions in a multi-stage decision situation. On this foundation, we will next consider the stochastic case of a finite-horizon Markovian Decision Process in discrete time, explain the optimality equations and their solution via the backward induction algorithm. Finally, we will consider the infinite-horizon, continuous time case of discounted Markov decision processes and the value and policy iteration algorithms to determine policies that are optimal in expectation.

On the fourth day, we will consider a linkage between stochastic modeling and optimization by treating two-stage linear programs using scenario techniques. Here we will use the GAMS modeling system to essentially embed a numerical simulation within an (formally deterministic) linear or mixed-integer linear optimization program. We will furthermore discuss either (and preferably) current research projects of the participants that involve probabilistic modeling or (alternatively) some interesting papers showing the methodologies taught in the course.

MREV – Call for Papers – Corporate responsibility: In the dilemma between trust and fake?

Seminar at the IUC Dubrovnik (April 3-7, 2017) & Special Issue

Seminar Organizers & Guest Editors:
Simon Fietze, University of Southern Denmark
Wenzel Matiaske, Helmut-Schmidt-University/University of the Federal Armed Forces Hamburg (Germany)
Roland Menges, Technical University Clausthal (Germany)

Trust is the currency that creates markets. This is knowledge of the merchants at the latest since modern markets have emerged along the medieval trade routes. Quality and reliability in the business are also building blocks of trust and the assumption of responsibility for the social and ecological consequences of entrepreneurial activity. Whether the latter should be integrated into social and legal relations and norms in the form of voluntary corporate responsibility, has been the subject of economic discussion since the beginnings of the discipline and since the separation of the spheres of economic and moral action in the Scottish moral economy.

Over the past decades, both supra-national organizations such as the UN and the EU have been focusing on soft law – from the global compact through the AA1000 to the Green Paper of the EU Commission – as well as the national states, to promote social and environmental responsibility for companies in the age of globalization. These initiatives have led to lively activities and debates both in the business world and in different scientific disciplines. For companies, it has now become a “fashion” to campaign social and ecological responsibility using the concept of “Corporate Social Responsibility”. This commitment has meanwhile led to the fact that CSR activities should partly contribute to value creation instead of aligning them with corporate objectives and values. Such a development leads to the loss of trust and the assumption of responsibility becomes a “fake”.

Against this backdrop, some of the social and economic observers remained skeptical, advocating tougher legal norms or fiscal implications. Finally, lawyers pointed out that (successful) standardizations often develop not only from the “top”, but also from the “bottom”, i.e. they emerge from the action routines of the economic actors as emergent effects. However, not only the recent scandals – from the ENRON case to the VW case – raise questions about the effectiveness of co-operative self-commitment as well as external control.

Moreover, corporate responsibility is related to the concept of consumer responsibility. Whereas market-optimists believe that reliable changes in consumption patterns rely on responsible individual action, more market-skeptics warn of a counterproductive “privatization of sustainability”.

In this light, this year’s seminar at the IUC Dubrovnik will be on theoretical and empirical contributions to the topic “Corporate responsibility: In the dilemma between trust and fake?” from economic, sociological, (economic) historical and legal perspectives. Possible topics are:

  • Economic and history of ideas cases and questions of corporate responsibility
  • The “pseudo” corporate responsibility
  • Organizational and sociological theories and findings on corporate responsibility
  • Theory and empiricism of the audit
  • Theoretical and empirical studies on consumer responsibility
  • Criminal law considerations for corporate actors
  • Institutional factors of corporate responsibility
  • The trust of social entrepreneurship
  • This is not an exhaustive list.

Deadline
Potential contributors to the seminar at the IUC Dubrovnik are encouraged to submit an abstract of 1-2 pages before February 28th, 2017 electronically via online submission system of Management Revue using ‘IUC Dubrovnik’ as article section: http://www.management-revue.org/submission/

Reminder – Call for Papers: Echoes of an Era – A Century of Organisational Studies

Special Stream of Management Revue (MREV)
Echoes of an Era – A Century of Organisational Studies

Managing Editor:
Wenzel Matiaske, Helmut-Schmidt-University Hamburg (Germany)

Hundred years ago, Henri Fayols “Administration Industrielle et Générale”, a milestone in the history of organizational thought, was published. This centenary motivates the editors of the Management Revue to launch a stream on the history of organiational studies. In the forthcoming volumes, and rather on an infrequent basis, we would like to publish contributions which not only introduce the reader to one or several, interrelated seminal works of organizational theory, but also provide accompanying commentaries and an analysis of their history of effects.

The reason for this format is, given our discipline’s forgetfulness of history, to provide orientation, which not only serves teaching and young management scholars. While reference to classic thought contributes to scientific advancement in other fields of the social sciences, in our field some research issues are being addressed over and over again – without putting the associated arguments and findings in an adequate historical context. In this respect, addressing the history of thought should be understood as a contribution to the advancement of management research.

We would like to avoid a strict delimitation of the era being addressed. Contributions on contemporaries of Fayol like Frederik Winston Taylor, Frank B. and Lillian Gilbreth or Henry L. Gantt und Karol Adamiecki are as welcome as contributions are on Fayol’s predecessors or successors. By  no means we are exclusively committed to the “engineers of the organisation”; economists, legal scholars and particularly the labour science community and psychologists should also be given due attention. A temporal upper boundary shall nevertheless be the 1970s, when, most notably induced by Alfred D. Chandler, strategic management and the reflection on it started to thrive.

This stream will be open to submissions until the end of 2017 in the first place. It will be maintained and edited by Wenzel Matiaske (Helmut-Schmidt-University Hamburg, Germany). Submissions shall accord with the formatting guidelines of the Management Revue. Please submit your manuscripts electronically via our online submission system using “SI Organisation Studies” as article section.

Looking forward to your contribution!
Wenzel Matiaske

New Book: Case Study Research Approaches, Methods, Contribution to Theory

9783957100757Hans-Gerd Ridder

Case Study Research
Approaches, Methods, Contribution to Theory

This book outlines the richness of case study approaches in their contribution to theory. It offers master and doctoral students a systematic overview of how to conduct case study research considering the variety of its approaches.

A continuum of theory is outlined in order to clarify the contribution of research designs to theory. Research topics, research questions, and the role of the theoretical and empirical state of the art are discussed. The conceptual framework is displayed as an orientation, guiding the study theoretically as well as methodologically.

The core of the book is the investigation into the main approaches of case study re-search. Exploratory, explanatory, constructivist, and extended case study approaches are outlined and compared. Commonalities and differences in data collection and data analysis within case study research are deepened.

Hans-Gerd Ridder holds the Chair in Human Resource Management at the Leibniz Universität Hannover. His research focuses on strategic HRM in Profit and Non Profit Organizations.
