Prior research on "strategic voting" has reached the conclusion that unanimity rule is uniquely bad: it results in destruction of information, and hence makes voters worse off. We show that this conclusion depends critically on the assumption that the issue being voted on is exogenous, i.e.,...

Democratic elections look very much like a contest where voters have to compare the candidates according to an ordinal ranking. Nevertheless, the theory of tournaments has not yet been applied to Political Economics. Therefore, we deploy tournament models to analyse elections. The main...

Prior research on quot;strategic votingquot; has reached the conclusion that unanimity rule is uniquely bad: it results in destruction of information, and hence makes voters worse off. We show that this conclusion depends critically on the assumption that the issue being voted on is exogenous,...

We outline a new voting procedure for representative democracies. This procedure should be used for important decisions only and consists of two voting rounds: a randomly-selected subset of the citizens is awarded a one-time voting right. The parliament also votes, and the two decisions are...

We study equilibrium selection in a common-interest voting model with three alternatives. In the model, symmetric Bayesian Nash Equilibria (BNE) of varying efficiency are known to exist. Employing evolutionary adaptive learning simulations, we find interesting new equilibria. In simulations, we...

In the last decade, social media and the Internet have amplified the possibility to spread false information, a.k.a. fake news, which has become a serious threat to the credibility of politicians, organizations, and other decision makers. This paper proposes a framework for investigating the...

In Colombia these polls do not withstand any rigorous testing. And contrary to expand the formation of public opinion, impaired. To overcome this defect should propose means fewer surveys and more discussions. Presidential campaigns should seek democratic enlargement, and a less massive media...

This paper investigates opportunities and approaches for forecasting the future, with a particular focus on Nobel prizes. We review different approaches, including using the “wisdom of the crowd” through approaches such as prediction markets. We drill down on prediction markets, analyzing...

Under Liquid Democracy (LD), decisions are taken by referendum, but voters are allowed to delegate their votes to other voters. Theory shows that in common interest problems where experts are correctly identified, the outcome can be superior to simple majority voting. However, even when experts...
