We study the problem of allocating heterogeneous indivisible tasks in a multi-object-demand model (i.e., each agent can be assigned multiple objects) where monetary transfers are allowed. Agents. costs for performing tasks are their private information and depend on what other tasks they are...

In the problem of assigning indivisible goods and monetary transfers, we characterize welfare-egalitarian mechanisms (that are decision-efficient and incentive compatible) with an axiom of solidarity under preference changes and a fair ranking axiom of order preservation. This result is in line...

We characterize welfare-egalitarian mechanisms (that are decision-efficient and incentive compatible) with the two fundamental axioms of fairness: no-envy and egalitarian-equivalence. We consider cases where agents have equal rights over external world resources but are individually responsible...

We study the allocation of collectively owned indivisible goods when monetary transfers are possible. We restrict our attention to incentive compatible mechanisms which allocate the goods efficiently. Among these mechanisms, we characterize those that respect the identical-preferences...

The significance of population monotonicity and welfare bounds is well-recognized in the fair division literature. We characterize population monotonic and incentive compatible mechanisms which allocate the goods efficiently and respect a welfare lower bound chosen in the fair allocation problem...

We study the problem of allocating objects when monetary transfers are possible. We are interested in mechanisms that allocate the objects in an efficient way and induce the agents to report their true preferences. Within the class of such mechanisms, first we characterize egalitarian-equivalent...
