Speed and quality of collective decision making: Incentives for information provision

Hans Peter Grüner, Elisabeth Schulte
2010 Journal of Economic Behavior and Organization  
It studies the role of the hierarchy design for the speed and quality of a collective decision process. We consider a programmed network of managers.  ...  The network's task is to aggregate information in form of a set of n data items and to make an informed decision. The programme describes how information is processed within the network.  ...  In Section 4, we study the incentives for information processing in a single decision maker organization and in a two-tier hierarchy, the centralized tree.  ...

Large-Scale Complex Systems [chapter]

Florin-Gheorghe Filip, Kauko Leiviskä
2009 Springer Handbook of Automation  
Siljak [36.3] states that a LSS is characterized by its high dimensions (large number of variables), constraints in the information infrastructure, and the presence of uncertainties.  ...  Complications may still be caused by system non-linearities, time delays, and different time constants, and, especially over recent years, risk sensitivity aspects.  ...  Dynamic, random nature is one main concern in operation control.  ...

The analysis suggests that concerns for fast decision-making may be key in explaining the recent trend towards empowerment in ...rms.  ...  This paper studies the optimal allocation of coordination responsibilities in organizations where duplication of e¤ort is a serious concern.  ...  Importantly, since communication e¤ort and span of control will be decision variables at each level of the hierarchy, this will allow me to compare their optimal levels across layers.  ...

Higher variability in dyadic interaction plays a positive role in the decision making of futsal passing

Umberto Cesar Corrêa, Flávio Henrique Bastos, Sílvia Letícia Silva, Fabian Alberto Romero Clavijo, Camila Torriani-Pasin
2020 Kinesiology  
This study investigated the role the dyadic interaction variability plays in influencing decision making on passing in the sport of futsal.  ...  Results showed that the interaction of passer and receiver dyads were more variable than the remaining dyads. Moreover, it was verified that the passer dyad had the highest variability.  ...  This study sought to understand how variability of dyadic interaction would influence the decision-making on passing in futsal.  ...

A Complexity Theory for Hard Enumeration Problems [article]

Nadia Creignou, Markus Kröll, Reinhard Pichler, Sebastian Skritek, Heribert Vollmer
2017 arXiv   pre-print
In particular, complexity classes analogous to the polynomial hierarchy and an appropriate notion of problem reduction are missing.  ...  In this work, we lay the foundations for a complexity theory of hard enumeration problems by proposing a hierarchy of complexity classes and by investigating notions of reductions for enumeration problems  ...  Concerning the remaining classes, observe that DelayP P C p = DelayP C p for any decision complexity class C; in particular we obtain DelayP ∆ P k p = DelayP Σ P k−1 p .  ...

Coordination and delay in hierarchies

Andrea Patacconi
2009 The Rand Journal of Economics  
The model suggests that concerns for fast execution may be key in explaining recent trends toward decentralization and delayering in firms.  ...  Simple conditions are provided for the time spent on coordinating subordinates to be increasing and the span of control to be decreasing as one goes up the hierarchy, with equalities holding if delay is  ...  In their setting, delay is costly because decisions based on old information become less appropriate over time.  ...
