This is the last of four papers devoted to the 2021 German federal elections continuing our analysis of the 2009, 2013 and 2017 Bundestag elections. It is shown that the policy representation by the Bundestag could be improved using the alternative Third Vote election method. Under the Third...

This paper investigates the role that idiosyncratic uncertainty plays in shaping social preferences over the degree of labor market flexibility, in a general equilibrium model of dynamic labor demand where the productivity of firms evolves over time as a Geometric Brownian motion. A key result...

In this paper we axiomatically characterize two recursive procedures for defining a social group. The first procedure starts with the set of all individuals who are defined by everyone in the society as group members, while the starting point of the second procedure is the set of all individuals...

This paper considers the object allocation problem introduced by Shapley and Scarf (1974). We study secure implementation (Saijo, Sjöström, and Yamato, 2007), that is, double implementation in dominant strategy and Nash equilibria. We prove that (i) an individually rational solution is...

In this paper, we reexamine Eliaz's results (2002) of fault tolerant implementation on one hand and we extend theorems 1 and 2 of Doghmi and Ziad (2008 a) to bounded rationality environments, on the other. We identify weak versions of the k-no veto power condition, in conjunction with unanimity...

The burgeoning literature on the use of sanctions to support public goods provision has largely neglected the use of formal or centralized sanctions. We let subjects playing a linear public goods game vote on the parameters of a formal sanction scheme capable both of resolving and of...

We consider the problem of allocating infinitely divisible commodities among a group of agents. Especially, we focus on the case where there are several commodities to be allocated, and agents have continuous, strictly convex, and separable preferences. In this paper, we establish that the...

I consider a society with heterogeneous individuals who can form organizations for the production of a differentiated service. An arrangement of organizations is said to be split up stable when there is no majority to split any of the organizations. Unlike other equilibrium concepts in the...

This paper takes a mechanism design approach to federalism and assumes that local preferences are the private information of local jurisdictions. Contractual federalism is defined as a strategy-proof contract among the members of the federation supervised by a benevolent but not omniscient...
