2020/16 Complexity of finding Pareto-efficient allocations of highest welfare Péter Biró - Jens Gudmundsson

We allocate objects to agents as exemplified primarily by school choice. Welfare judgments of the object-allocating agency are encoded as edge weights in the acceptability graph.  The welfare of an allocation is the sum of its edge weights. We introduce the constrained welfare-maximizing solution, which is the allocation of highest welfare among the Pareto-efficient allocations. We identify conditions under which this solution is easily determined from a computational point of view. For the unrestricted case, we formulate an integer program and find this to be viable in practice as it quickly solves a real-world instance of kindergarten allocation and large-scale simulated instances. Incentives to report preferences truthfully are discussed briefly.

2020/15 Indexing public pensions in progress to wages or prices András Simonovits

Initial public pensions are indexed to the economy-wide average wages, but pensions in progress are indexed to prices, average wages or their combinations––varying across countries and periods. We create a simple overlapping cohorts framework to study the properties of indexing pensions in progress––emphasizing a neglected issue: close wage paths should imply close benefit paths even at real wage shocks. This robustness criterion of an equitable pension system is only satisfied by wage indexing, which in turn requires the adjustment of the accrual rate. To minimize the redistribution from low-earning short-lived citizens to high-earning long-lived ones, progression should be introduced.
