According to a minimalist version of Afriat's theorem, a consumer behaves as a utility maximizer if and only if a feasibility matrix associated with his choices is cyclically consistent. An essential experiment consists of observed consumption bundles (x_1,..., x_n) and a feasibility matrix...

The aim of this paper is to test the presence of strategic interactions in government spending on Research and Development (R&D), among EU-15 countries. We add to the literature on public choice strategic interactions in general, and to work on R&D spending in particular. We take account of...

Potential based no-regret dynamics are shown to be related to fictitious play. Roughly, these are epsilon-best reply dynamics where epsilon is the maximal regret, which vanishes with time. This allows for alternative and sometimes much shorter proofs of known results on convergence of no-regret...
