A previous article investigated the semantic distinction between the analytical and the synthetic, and applied it to microeconomics; in the present one, the fundamental propositions of this field come to terms with the epistemological distinction between the a priori and the a posteriori (or...

This article applies to microeconomics a classic distinction of the philosophy of language, i.e., that between analytical and synthetic propositions.

Résumé d'article. L'article examine et conteste la conception néo-poppérienne de l'explication en sciences sociales que propose Maurice Lagueux dans son ouvrage Rationality and Explanation in Economics (2010). Inspiré par l'article célèbre de Popper (1967) sur le principe de rationalité,...

Author's abstract. Judgment aggregation theory generalizes social choice theory by having the aggregation rule bear on judgments of all kinds instead of barely judgments of preference. The paper briefly sums it up, privileging the variant that formalizes judgment by a logical syntax. The theory...

Author's abstract. Approval voting has attracted considerable interest among voting theorists, but they have rarely investigated it in the Arrovian frame-work of social welfare functions (SWF) and never connected it with Arrow’s impossibility theorem. This note explores these two direc- tions....

The paper suggests that military history should be subjected to modelling based on the mathematical theories of rational choice, and especially the theory of games. This suggestion primarily concerns military events that have already been reported in narratives focusing on the agents'...

In this paper, the authors investigate judgment aggregation by assuming that some formulas of the agenda are singled out as premisses, and the Independence condition (formula-wise aggregation) holds for them, though perhaps not for others.

This essay discusses the status of normative economics by identifying several conceptions that economists have entertained in this respect. It connects these conceptions with two main philosophical strands, i.e., positivism in its many variants and Weber's philosophy of values. The paper argues...

According to a theorem recently proved in the theory of logical aggregation, any nonconstant social judgment function that satisfies independence of irrelevant alternatives (IIA) is dictatorial. The author shows that the strong and not very plausible IIA condition can be replaced with a minimal...

Judgment (or logical) aggregation theory is logically more powerful than social choice theory and has been put to use to recover some classic results of this field. Whether it could also enrich it with genuinely new results is still controversial. To support a positive answer, the authors prove...
