We study a general barter market where every agent is endowed with several heterogeneous indivisible items and wishes to exchange. There no medium of exchange like money. Agents have preferences over their interested bundles may acquire items. propose practical sensible solution called Markovian core, generalizing the classical notion core. A core allocation individually rational, Pareto-effici...

Barter sistemi, Türkçe literatürdeki çalışmaların özellikle bazılarında hem bütünüyle tutarsız bir terminoloji kullanılarak de kendine özgü bazı yönleriyle doğrudan bağdaştırılamayacak çıkarımlarda bulunularak açıklanmıştır. Bu çalışmanın amacı, barter sistemi ile ilgili yapılmış çalışmalardaki açıklamaları inceleyerek, sistemle noktaları tespit edip bu eleştirel bakış açısıyla değerlendirmek s...

We present a novel knowledge-based approach for automated electronic barter trade systems. An e-barter is basically a closed e-marketplace, where agents may exchange (buy/sell) goods –or equivalent trade dollars– only with other participants to the e-barter. Obviously, in such systems one of the major issues is keeping exchanges as balanced as possible. If the description of goods or services t...

Differential auction–barter (DAB) model augments the well-known double auction (DA) model with barter bids so that besides the usual purchase and sale activities, bidders can also carry out direct bartering of items. The DAB model also provides a mechanism for making or receiving a differential money payment as part of the direct bartering of items, hence, allowing bartering of different valued...

We introduce a model for agent specialization in small-scale human societies that incorporates planning based on social influence and economic state. Agents allocate their time among available tasks based on exchange, demand, competition from other agents, family needs, and previous experiences. Agents exchange and request goods using barter, balanced reciprocal exchange, and generalized recipr...

OUNTERTRADE is tied trade. In a typical transaction a CPE or LDC imports goods and the exporting party usually a firm in a western industrial country commits itself to make an offsetting purchase at some future date. Since the mid seventies countertrade has become a significant phenomenon in international trade. Reasonable estimates vary between 10 and 20 per cent of world trade (see OECD, 1985...

The idea of this paper is an advanced game concept. This concept is expected to model non-monetary bilateral co-operations between selfinterested agents. Such non-monetary cases are social co-operations, for example, allocation of high level jobs or finding a suitable partner to marry. In a barter double auction, there is a set of agents. Every agent has a vector of parameters which specifies h...
