Level-Strategyproof Belief Aggregation and Application to Majority Judgment under Uncertainty

Explore a comprehensive talk on level-strategyproof belief aggregation and its application to majority judgment under uncertainty. Delve into expert predictions, social choice theory, and monetary transfers. Examine budget aggregation, phantom movie mechanisms, and key concepts like cumulative probability, preservation of certainty, and plausibility preservation. Investigate phantom functions, characterization of methods, order functions, and order cumulative. Learn about middlemost cumulative, extension, majority judgments, and their properties. Gain valuable insights into this complex topic through examples and in-depth analysis presented by Rida Laraki in the One World Mathematical Game Theory seminar.
