However, since an offer for the PD includes a share for all the m issues, agents can now make tradeoffs across the issues in order to maximise their cumulative utilities. The function TRADEOFFA is agent a’s function for making tradeoffs, and is described in more detail in the proof of Theorem 1. The function TRADEOFFB for b can be defined analogously. The equilibrium offer for issue c at time t is denoted as [atc , btc ], where atc and btc denote the shares for a and b. We denote the equilibrium package at time t as [at , bt ] t m where at ∈ Rm 1 (b ∈ R1 ) is an m element vector that denotes a’s (b’s) share for each of the m issues.

For each bid, it firstly obtains the number of goods to jointly bid for from a geometric distribution (line 3). It subsequently obtains the number of units to offer per good (line 8) from another geometric distribution. We employed geometric distributions since they provide large variances. Once generated the units to offer per good for all bids, we must assess all bid prices. This process is rather delicate when considering t-relationships if we want to guarantee the production of a set of plausible bids.

Given these beliefs, strategies A and B are sequentially rational. 1. , na = 1) be the offering agent at t = 1. Since r = 2, a can play two possible strategies at t = 1: one corresponding to the case where b is of type 1 and the other to the case where b is of type 2. For the former, a’s equilibrium offer at t = 1 is [1, 0] for each issue. 7. 675] for the first issue and [1, 0] for the second one. 325. Since EUA (1, 1, 1) > EUA (1, 2, 1), OPTA (1, 1) = 1 and a plays the former strategy. Now if b is actually of type 1, then it accepts a’s offer.
