In economics and other social sciences, complex processes are often represented by numerical models of reality which more or less well reflect behavioral relationships and interactions. Such attempts are the subject of a lecture course "Mathematical Theory of Democracy" by the author at the...

Pivato and Soh [Pivato, M., Soh, A., 2020. Weighted representative democracy. Journal of Mathematical Economics 88 (2020) 52--63] proposed a new system of democratic representation whereby any individual can choose any legislator as her representative and different legislators can represent...

The paper challenges the "orthodox doctrine" of collective choice theory according to which Arrow's "general possibility theorem" precludes rational decision procedures generally and implies that in particular all voting procedures must be flawed. I point out that all voting procedures are...

This paper studies, theoretically and experimentally, the effects of overconfidence and fake news on information aggregation and the quality of democratic choice in a common interest setting. We theoretically show that overconfidence exacerbates the adverse effects of widespread misinformation...

Do emotions affect the decision between change and the status quo? We exploit exogenous variation in emotions caused by rain and analyze data on more than 870,000 municipal vote outcomes in Switzerland to address this question. The empirical tests are based on administrative ballot outcomes and...

There is a concern that citizens with different political positions and party affiliations increasingly dislike each other. We examine this affective polarization (AP), which is often associated with a weakening of democracy, in the context of Switzerland's multiparty landscape with proportional...

Populists claim to be the only legitimate representative of the people. Does it mean that there is no space for civil society? The issue is important because since Tocqueville (1835), associations and civil society have been recognized as a key factor in a healthy liberal democracy. We ask two...

What determines citizens satisfaction with the constitution in operation ? We make two contributions towards an answer to this important policy question. First, we place stronger emphasis than existing studies on quantitative interpretations of the importance of different factors. We use...
