Consider trade in continuous time between two players. The gains from trade are divided according to a contract, and at each point in time, either player may unilaterally induce a costly adjustment of the contract. Players' payoffs from trade under the contract, as well as from trade under an...

Analyzing the decay properties of the Green's function for a particular Schrödinger operator on L2(R) we show that in a suitable sense there is no diffusion when the energy is near the bottom of the spectrum.

Necessary and sufficient conditions for uniform geometric convergence in the relative supremum norm of the Metropolis-Hastings simulation algorithm with a general generating function are established. An explicit expression for the convergence rate is given.

This paper lays out a simple open economy macromodel based on the recent literature on imperfect competition and equilibrium unemployment. It is shown that the NAIRU is not a clearcut concept in the open economy framework. Furthermore, it is argued that the self-correcting mechanisms in the...

We study the possible existence of downward nominal wage rigidity (DNWR) at wage growth rates different from zero in aggregate data. Even if DNWR prevails at zero for individual workers, compositional effects might lead to falling aggregate wages, while changes in relative wages combined with...

In a long-term relationship between two parties, one party's threat of a unilateral violation of an initial contract may induce a renegotiation of the contract. As a renegotiation may result in one party capturing some of the return from the other's investments, this possibility may lead to...
