On Market Games When Agents Cannot be Two Places at Once

We consider markets in which agents aupply one unit of time that is equal to the duration of the market. We show that a coalitional game can be generated by such a market if and only if the characteristic function of the game is superadditive. We also characterize the vectors of balancing weights that are associated with feasible plans for forming coalitions in a time-constrained market. These are shown to be the same as the ones generated from a market with indivisible agents and lotteries.
