The Joint TADA/AMEC Workshop introduced jointly the 2 winning and well-established occasions of the buying and selling Agent layout and research (TADA) and Agent-Mediated digital trade (AMEC) Workshops. The TADA sequence of workshops serves as a discussion board for offering paintings on buying and selling agent layout and applied sciences, theoretical and empirical assessment of techniques in advanced buying and selling eventualities in addition to mechanism layout. TADA additionally serves because the major discussion board for the buying and selling Agent pageant (TAC) study neighborhood. TAC is an annual match whose objective is to stimulate learn in buying and selling brokers and industry mechanisms via delivering a platform for brokers competing in we- de?ned industry eventualities (http://www. sics. se/tac). The AMEC sequence of wo- outlets offers interdisciplinary researchon either theoretical and useful problems with agent-mediated digital trade starting from the layout of digital marketplaces and e?cient protocols to behavioral facets of brokers working in suchenvironments.

In the same way, the computation for each time period t < Nr takes O(mr3 ) time. Hence, the total time to find the equilibrium offer for t = 1 is O((Nr − 1)mr3 ). However, as noted previously, an agreement may or may not occur at t = 1. If it does not, then the agents update their beliefs and find the equilibrium offer for t = 2. The time to compute the equilibrium offer for t = 2 is O((Nr − 2)mr3 ). This process of updating beliefs and finding the equilibrium offer is repeated at most T = min(2r − 1, n) times (see the last paragraph of the proof for Theorem 7).

However, for such encounters, the outcome depends on the procedure that is used [6]. Such procedures specify how the issues will be settled. Broadly speaking, there are three possibilities: (i) Discuss the issues together as a package deal (PD). This gives rise to the possibility of making tradeoffs across issues. (ii) Discuss the issues simultaneously, and independently of each other. This is called the simultaneous procedure (SIM). (iii) Discuss the issues one after another. This is called the sequential procedure (SEQ).
