We study the problem of allocating objects when monetary transfers are possible. We are interested in mechanisms that allocate the objects in an e cient way and induce the agents to report their true preferences. Within the class of such mechanisms, rst we characterize egalitarian-equivalent mechanisms. Then, we add a bounded-de cit condition and characterize the corresponding class. Finally, w...

The purpose of this paper is to analyze the advantages and disadvantages of several intermediate inequality measures, paying special attention to whether inequality rankings between income distributions are affected by the monetary units in which incomes are expressed. In particular, we show why one of the most popular intermediate inequality approaches, that proposed by Bossert and Pfingsten (...

Within the framework of pure redistribution (dividing one unit of a homogeneous good among identical individuals), the paper analyses the redistribution that arises from Downsian, two-party, electoral competition. It appears that the strategic behavior of vote-maximizing parties leads them to propose divisions which are not far from the egalitarian one. Journal of Economic Literature Classifica...

The domain of polyconvex sets, i.e. finite unions of convex, compact, Euclidean sets, is large enough to encompass most of the opportunity sets typically encountered in economic environments, including non-linear or even non-convex budget sets, and opportunity sets arising from production sets. We provide a characterization of the volume-ranking as defined on the set of all polyconvex sets, rel...

Our research is a variant of the third party punishment game. In particular, we want to test whether players have heterogeneous preferences; the levels of the sanction and of the transfer are proportional to the unfairness of the Dictator; the change of the role influences the Observer’s reaction to unfair behavior; players’ decision to punish the Dictator and/or to help the Receiver depends on...

β-fructofuranosidase (β-FFase) belongs to the glycosyl-hydrolase family 32 (GH32), which can catalyze both the release of β-fructose from β-d-fructofuranoside substrates to hydrolyze sucrose and the synthesis of short-chain fructooligosaccharide (FOS). BmSuc1 has been cloned and identified from the silkworm Bombyx mori as a first animal type of β-FFase encoding gene. It was hypothesized that Bm...
