Anti-Limit Pricing
Extending Milgrom and Roberts (1982), we analyze an infinite horizon entry model where an incumbent may use its current price to signal its strength, in order to deter entry. In contrast with conventional limit pricing, we show the entry of weaker firms. We also provide necessary and sufficient conditions for this phenomenon to arise in equilibrium, in the benchmark cases that no second entry is profitable.Dynamic Signaling, Limit Pricing, Entry Deterrence
Mass and Angular momentum of Black Holes in New Massive Gravity
We obtain mass and angular momentum of black holes as conserved charges in
three dimensional new massive gravity, after presenting the explicit expression
for the potential of the conserved charges. This confirms the expression of
those charges obtained in several ways, in particular through AdS/CFT
correspondence, and shows us that the first law of black hole thermodynamics is
valid in these black holes. We also comment about conserved charges in new type
black holes with the emphasis on the AdS/CFT correspondence as guiding
principle.Comment: minor corrections, added conclusion, accepted in PR
Quasi-local charges and asymptotic symmetry generators
The quasi-local formulation of conserved charges through the off-shell
approach is extended to cover the asymptotic symmetry generators. By
introducing identically conserved currents which are appropriate for asymptotic
Killing vectors, we show that the asymptotic symmetry generators can be
understood as quasi-local charges. We also show that this construction is
completely consistent with the on-shell method.Comment: 19 pages; v2 typos fixe
