Lars von Trier's movie 'Dogville' illustrates some illuminating and poignant comparative statics of equilibrium allocations, according to Heike Harmgart and Steffen Huck
The miracle as a randomization device: a lesson from Richard Wagner's romantic opera Tannhauser und der Sankerkrieg auf Wartburg
In this paper we provide textual evidence on the sophistication of medieval deterrence
strategies. Drawing on one of the great opera librettos based on medieval sources, Wagner’s
Tannhäuser, we shall illustrate the use of optimal randomization strategies that can be derived
by applying notions of dominance or trembling-hand perfection. Particular attention is paid to
the employed randomization device
“Though this be madness, yet there is method in’t.” A counterfactual analysis of Richard Wagner’s Tannhäuser
Much like Wagner himself, the eponymous hero of Tannhäuser treads a path of stark contrasts and
rapid swings. From Wartburg to the Venusberg and to the Vatican, the gifted bard transforms from
self-centered artist to seduced disciple, disillusioned devotee, hopeful lover, self-loathing pilgrim and
finally redeemed martyr. He tries everything and everything is trying. These contrasts reach a peak in
the opera‟s central episode, the song contest at Wartburg. Tannhäuser has just been welcomed at the
court, received Elisabeth‟s favor and affection, and is ready to compete for the contest‟s prize, one as
lofty as possibly the princess‟ hand. Instead of securing his reintegration to Wartburg with a brilliant
performance, however, he spoils the event with insolent remarks and the exhibitionist disclosure of
his Venusberg experience. His behavior offends his peers, scandalizes the court, breaks Elisabeth‟s
heart, and brings him to the edge of death. Why would Tannhäuser sacrifice everything for nothing
Learning trust
We examine the effects of different forms of feedback information on the performance of markets that suffer from moral hazard problems due to sequential exchange. As orthodox theory would predict, we find that providing buyers with information about sellers' trading history boosts market performance. More surprisingly, this beneficial effect of incentives for reputation building is considerably enhanced if sellers, too, can observe other sellers' trading history. This suggests that two-sided market transparency is an important ingredient for the design of well-functioning markets that are prone to moral hazard
Forbidden subgraphs that imply Hamiltonian-connectedness
It is proven that if is a -connected claw-free graph which is also -free (where is a triangle with a path of length attached), -free (where is a path with vertices) or -free (where consists of two disjoint triangles connected by an edge), then is Hamiltonian-connected. Also, examples will be described that determine a finite family of graphs such that if a 3-connected graph being claw-free and -free implies is Hamiltonian-connected, then . \u
