The international, interdisciplinary journal Mathematical Social Sciences publishes original research, survey papers and short notes, as well as news items, abstracts and book reviews. The journal emphasizes the unity of mathematical modelling in economics, psychology, political sciences, sociology and other social sciences. Papers published by the journal are mathematically rigorous but no bounds, from above or from below, limits their technical level. Mathematical techniques include, but are not limited to: axiomatic methods, combinatorial methods, graph theory and ordered structures, lattices and Boolean algebra, probability and statistics, functional analysis and fixed points, differential equations, dynamical and/or stochastic systems, optimization, control theory. Topics of particular interest include individual choice and preference, decision under risk and uncertainty, collective choice and preferences, consensus theory, the measurement of utility, of social welfare, of inequality, distributive justice, the equilibrium of socioeconomic systems, game theory, evolutionary models, social networks, fair division and cost allocation, voting rules and implementation theory, team theory, and planning.
