Research Type Theoretical In this paper, we improve upon these bounds, even in a wider model. Namely, we show that, given an EF1 allocation, we can compute in polynomial time an envy-free allocation with a subsidy of at most n 1 per agent and a total subsidy of at most n(n 1)/2. Moreover, we present further improved bounds for monotone valuations. and To prove these improved bounds, we reveal that the structure of the minimum subsidy vectors satisfies: (i) the minimum subsidy vector remains unchanged irrespective of the maximum weight matching (Lemma 2), and (ii) how the subsidies alter when the weights are changed (Lemma 4).
