We propose a new axiom, Weakest Collective Rationality (WCR) which is weaker than both Weak Pareto Optimality (WPO) in Nash (1950)’s original characterization and Strong Individual Rationality (SIR) in Roth (1977)’s characterization of the Nash bargaining solution. We then characterize the...

Suppes-Sen Dominance is a commonly accepted criterion of impartiality in distributive justice. Mariotti (1999) characterized the Nash bargaining solution using Nash (1950).s Scale Invariance (SI) axiom and an axiom named Suppes-Sen Proofness (SSP) that embodies the Suppes-Sen principle. By...

In most macroeconomic models inflation tends to be harmful. In this paper we show that by simply changing the timing of production decisions by firms from “on demand” to “in advance”, some inflation can boost welfare as long as goods are sufficiently perishable. The main conclusion from...
