In the early 1970s, Kihlstrom and Evans reported that hypnotizable subjects who remembered at least some of the items in a standardized hypnotic susceptibility scale, despite a suggestion for complete amnesia, tended not to recall these items in the order in which they had been administered; insusceptible subjects, by contrast, tended to recall the items sequentially (Evans & Kihlstrom, 1973; K...

Acknowledgement: I appreciate the constructive comments of Andrew Austin and three anonymous referees for the Journal of Economic Education. Abstract I present a brief classroom demonstration illustrating Bertrand price undercutting. The classroom demonstration is appropriate for Micro Principles, and both intermediate and upper level undergraduate, as well as graduate classes in micro, Industr...

the misconception (shubha) of absolute nonexistent – which we have named as paradox – is not an amusing brainteaser; rather, it is one the significant epistemological issues. its importance can be looked upon from two different viewpoints: research and educational. it is significant from the research viewpoint because it challenges propositions which constitute the foundation of our thinking an...

Unique Nash Equilibrium: p1 = p2 = c. Proof: If pi = c, then there is no price at which firm j can earn strictly positive profit so that pj = c is a best response. Thus, p1 = p2 = c is a NE. To show uniqueness, note that if c < pi < pj , then firm j earns zero profit and can do strictly better by unilaterally deviating and charging a price ∈ (c, pi). If c = pi < pj , then firm i earns zero prof...

Perlick’s classification of (3 + 1)-dimensional spherically symmetric and static spacetimes (M, η = − 1 V dt + g) for which the classical Bertrand theorem holds [Perlick V 1992 Class. Quantum Grav. 9 1009] is revisited. For any Bertrand spacetime (M, η) the term V (r) is proven to be either the intrinsic Kepler– Coulomb or the harmonic oscillator potential on its associated Riemannian 3manifold...
