Generalized search-theoretic models of monetary exchange
This paper extends the literature on search-theoretic models of money in several ways. It provides results for general bargaining parameters, whereas previous papers consider only special cases. It also presents one version of the model in which agents holding money cannot produce and another in which they can. The former has been used in essentially all the previous literature, although the latter seems more natural for some purposes and avoids several undesirable implications. Since very little is known about this version, the authors analyze it in detail.Monetary theory
The search-theoretic approach to monetary economics: a primer
The authors present simple versions of models used in the search-theoretic approach to monetary economics. They discuss results on the existence of monetary equilibria, the potential for multiple equilibria, and welfare. Using bilateral bargaining theory, they consider models where prices are fixed as well as those where prices are determined endogenously. After describing the frictions necessary to construct a model where money has an essential role, they conclude by reviewing many extensions and applications in the related literatureMoney
Escape rates in periodically driven Markov processes
We present an approximate analytical expression for the escape rate of
time-dependent driven stochastic processes with an absorbing boundary such as
the driven leaky integrate-and-fire model for neural spiking. The novel
approximation is based on a discrete state Markovian modeling of the full
long-time dynamics with time-dependent rates. It is valid in a wide parameter
regime beyond the restraining limits of weak driving (linear response) and/or
weak noise. The scheme is carefully tested and yields excellent agreement with
three different numerical methods based on the Langevin equation, the
Fokker-Planck equation and an integral equation.Comment: 10 pages, 5 figure
A Multi-Chamber System for Analyzing the Outgassing, Deposition, and Associated Optical Degradation Properties of Materials in a Vacuum
We report on the Camera Materials Test Chamber, a multi-vessel apparatus
which analyzes the outgassing consequences of candidate materials for use in
the vacuum cryostat of a new telescope camera. The system measures the
outgassing products and rates of samples of materials at different
temperatures, and collects films of outgassing products to measure the effects
on light transmission in six optical bands. The design of the apparatus
minimizes potential measurement errors introduced by background contamination.Comment: 9 pages, 10 figures, published in RSI (minor edits made to match
