We present two new notions of evolutionary stability, the truly evolutionarily stable state (TESS ) and the generalized evolutionarily stable equilibrium (GESE ). The GESE generalizes the evolutionarily stable equilibrium (ESE ) of Joosten [1996]. An ESE attracts all nearby trajectories monotonically, i.e., the Euclidean distance decreasing steadily in time. For a GESE this property should hold...

The notion of ‘mathematical impossibility’ of group decision making is founded on errors in microeconomics, game theory, and related disciplines. We highlight mathematical errors that have been committed by von Neumann and Morgenstern, Pareto, Hicks, Samuelson, and Debreu which have been propagated throughout the social sciences.

In pay-as-you-go financed pension plans, pension payments to the retired are not drawn from a capital fund accumulated during their working lives but financed directly by the contributions of the current workers/contributors (see e.g. AARON (1982, 7)). As SAMUELSON (1958) and AARON (1966) have shown, this financing method can provide every generation of workers with a better internal rate of re...

A large literature uses matching models to analyze markets with two-sided heterogeneity, studying problems such as the matching of students to schools, residents to hospitals, husbands to wives, and workers to firms. The analysis typically assumes that the agents have complete information, and examines core outcomes. We formulate a notion of stable outcomes in matching problems with one-sided a...
