We consider envy-free and budget-balanced allocation rules for problems where a number of indivisible objects and a fixed amount of money is allocated among a group of agents. In "small" economies, we identify under classical preferences each agent's maximal gain from manipulation. Using this...

In many real-life house allocation problems, rents are bounded from above by price ceilings imposed by a government or a local administration. This is known as rent control. Because some price equilibria may be disqualified given such restrictions, this paper proposes an alternative equilibrium...

We consider envy-free and budget-balanced rules that are least manipulable with respect to agents counting or with respect to utility gains, and observe that for any profile of quasi-linear preferences, the outcome of any such least manipulable envy-free rule can be obtained via agent-k-linked...

Medical technology making kidney transplantation over the blood group barrier possible is now a reality. This paper investigates how such technology should be implemented when designing pairwise kidney exchange programs. The possibility to receive a kidney transplant from a blood group...

We consider taxation of exchanges among a set of agents where each agent owns one object. Agents may have different valuations for the objects and they need to pay taxes for exchanges. We show that if a rule satisfies individual rationality, strategyproofness, constrained efficiency, weak...

We consider an allocation problem with a finite number of objects, and agents that demand at most one of the objects. The study provides a characterization of a class of strategy-proof price mechanisms. A mechanism belongs to the class if and only if the price space is restricted in a special...

We analyze the problem of allocating indivisible objects and monetary compensations to a set of agents. In particular, we consider envy-free and budget-balanced rules that are least manipulable with respect to agents counting or with respect to utility gains. A key observation is that, for any...

We investigate empirically how electoral democracy and judicial independence relate to personal freedom. While judicial independence is positively and robustly related to personal freedom in all its forms, electoral democracy displays a robust, positive relationship with only two out of seven...

Public policies in a pluralistic society should be able to clarify and cope with the complicated nature of public issues dominated by multiple parties, multiple values, and subjective judgment. Therefore, instead of merely concluding with the outcome, we should also take input into account when...

Dieser Beitrag untersucht die Arbeiten von Jon Elster zum Problem lokaler Gerechtigkeit. Das Thema dieser Arbeiten sind Rationierungsentscheidungen. Es geht um die Allokation und Distribution knapper Zuteilungsgüter, also etwa um die Vergabe von Kindergarten- oder Studienplätzen, die Zuweisung...
