Noisy Information and Fundamental Disagreement

Disagreement and Information Collection

This note shows that disagreement, in the sense of differing priors, may increase the incentives to collect information when two agents work on a joint project. The reason is that each agent believes that new data will confirm his own beliefs and thus ‘convince’ the other agents to do what the focal agent thinks is right.

Fundamental Disagreement of Wave Mechanics with Relativity

(This work has been copyrighted with the Library of Congress) A number of well-known difficulties in physics resulted from merging the theory of relativity with the Compton-de Broglie wave mechanics. Two such problems were the failure of Dirac’s relativistic wave equation to predict the correct velocity of the electron, and the fact that the measured yield from nuclear fission was found to be s...

Strategic information disclosure when there is fundamental disagreement: an empirical investigation

Opinion dynamics with disagreement and modulated information

Abstract Opinion dynamics concerns social processes through which populations or groups of individuals agree or disagree on specific issues. As such, modelling opinion dynamics represents an important research area that has been progressively acquiring relevance in many different domains. Existing approaches have mostly represented opinions through discrete binary or continuous variables by exp...

Political disagreement and information in elections

We study the role of re-election concerns in the incentives of incumbent parties to engage in policy experimentation. In a probabilistic voting model, candidates representing two groups of voters compete for o ce. In equilibrium, the candidate representing the majority group wins with a probability that increases in the degree of political disagreement — the di↵erence in expected payo↵s from th...
