Introduction to dynamic belief elicitation

Christopher P. Chambers, Nicolas S. Lambert
2015 ACM SIGecom Exchanges  
We present a protocol for eliciting dynamic beliefs from forecasters. At time t = 0, forecasters hold beliefs about a random variable of interest that will realize publicly at time t = 1.  ...  The information elicited can be used to solve optimally an arbitrary dynamic decision problem.  ...  Alternatively, the decision maker may extract beliefs from the agents and then use these beliefs to decide on the best course of action.  ...

A fusion architecture based on TBM for camera motion classification

M. Guironnet, D. Pellerin, M. Rombaut
2007 Image and Vision Computing  
To ensure the temporal coherence of motions, a filtering of belief masses according to TBM is achieved. The second stage carries out a separation between static and dynamic frames.  ...  We propose in this paper an original method of camera motion classification based on Transferable Belief Model (TBM).  ...  Thus a new BBA is defined and is based on the following rule: if a certain number of frames around the frame studied have a belief on the static hypothesis (respectively dynamic) then a belief mass will  ...

Public Goods Provision with Rent-Extracting Administrators

Tobias Cagala, Ulrich Glogowsky, Veronika Grimm, Johannes Rincke
2017 Social Science Research Network  
Analysing the dynamic interactions between the contributors and the administrator, we demonstrate that rent-extraction and cooperation shocks trigger short-run adjustments in the agents' behaviour.  ...  This explains the long-run resilience of cooperation to rent extraction.  ...  Importantly, the form of belief updating by contributors drives the dynamics in our game.  ...
