This paper sets up a matching (decentralized trade) model with a technology that allows each pair of agents to report the transfer of goods in the end of each pairwise meeting. It examines (a) conditions under which an allocation that can be supported as an equilibrium allocation, and (b) whether the report system can replace money. JEL Classification: E40

A monoclonal antibody, mAb E40, that specifically recognizes hair cells and photoreceptors was derived from a mouse immunized with a membrane fraction prepared from the sensory maculae of the chick inner ear. In the mature chick inner ear, punctate labeling is observed along each stereocilium, but staining is mostly concentrated around the basal end of the sensory hair bundles, where it is clos...

INTRODUCTION The purpose of this study is to compare extrusion of irrigants delivered with a 27-G needle or the EndoVac system (Discus Dental, Culver City, CA) during instrumentation and final irrigation of teeth. METHODS Matched paired single canal teeth were divided into four sample groups and controls. The experimental groups were needle irrigation International Standards Organization (ISO...

OBJECTIVE The Third Report of the Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults, Adult Treatment Panel III (ATP III) encouraged reduced low-density lipoprotein (LDL) cholesterol levels for a greater number of patients and reemphasized the benefits of high-density lipoprotein (HDL) cholesterol. The purpose of this study was to compare 2 regimens achievi...

We address the question of existence of equilibrium in general timing games with complete information. Under weak assumptions, any two-player timing game has a Markov subgame perfect e-equilibrium, for each e40: This result is tight. For some classes of games (symmetric games, games with cumulative payoffs), stronger existence results are established. r 2004 Elsevier Inc. All rights reserved. J...

The following articles are being highlighted as part of Circulation’s Topic Review series. This series summarizes the most important manuscripts, as selected by the editors, published in Circulation and the Circulation subspecialty journals. The studies included in this article represent the Editors’ Picks for each Circulation: Cardiovascular Quality and Outcomes’ issue published in 2011. (Circ...

Yersinia adhesin A (YadA) is an essential virulence factor for the food-borne pathogens Yersinia enterocolitica and Yersinia pseudotuberculosis. Surprisingly, it is a pseudogene in Yersinia pestis. Even more intriguing, the introduction of a functional yadA gene in Y. pestis EV76 was shown to correlate with a decrease in virulence in a mouse model. Here, we report that wild type (wt) Y. enteroc...

This paper contributes to the micro-foundation of money in centralized markets with idiosyncratic uncertainty. It shows existence of stationary monetary equilibria and ensures that there is an optimum quantity of money. The rational solution of our model is compared with actual behavior in a laboratory experiment. The experiment gives support to the theoretical approach. JEL classification: C73...

In an economy with commodity-pairwise trading posts and transaction costs, commodity money is endogenously determined in general equilibrium. Absent double coincidence of wants, the lowtransaction cost commodity (with the narrowest proportional bid/ask price spread) becomes the common medium of exchange. JEL Classification: C62, E40

Background: A primary focus of self-care interventions for chronic illness is the encouragement of an individual's behavior change necessitating knowledge sharing, education, and understanding of the condition. The use of the Internet to deliver Web-based interventions to patients is increasing rapidly. In a 7-year period (1996 to 2003), there was a 12-fold increase in MEDLINE citations for “We...
