  • Direct or representative democracy? Co-Voting

  • Optimal democratic mechanisms

    Open AccessHans Gersbach, Stephan Imhof et al.ARTICLESocial Choice and Welfare2025

    Who should set the agenda in a democracy—the majority or the minority? We address this question by studying public project provision, financing, and redistribution within democratic institutions. We show that the four features defining the following procedure are locally necessary, and together sufficient, for optimality: (i) there are two proposal-making rounds followed by a voting round (with majority rule); (ii) a member of the minority propos…

  • Semi-flexible majority rules for public good provision

    Open AccessHans Gersbach, Oriol TejadaARTICLESocial Choice and Welfare2024

    We introduce semi-flexible majority rules for public good provision with private valuations. Such rules take the form of a two-stage, multiple-round voting mechanism where the output of the first stage is the default alternative for the second stage and the vote-share thresholds used in every round of binary voting (a) vary with the alternative on the table for a public-good level and (b) require a qualified majority for approving the alternative…

  • Lemons and peaches

    Open AccessHans Gersbach, Akaki Mamageishvili et al.ARTICLEMathematical Social Sciences2022References: 44

    We introduce a four-stage, multi-price buying mechanism which can be used by a (big) buyer to separate low-quality sellers – called “lemon” owners – from high-quality sellers – called “peach” owners. With a partition of sellers into several groups, the buyer obtains the commodities from a desired number of “peach” owners at a price that matches their willingness to sell. For their part, “lemon” owners are trapped into selling their items at a low…

  • A Differential Redistributive Analysis of Bilinear Dual-Income-Tax Reforms

    Samuel Calonge, Oriol TejadaARTICLEFinanzArchiv2011

    We analyze differential redistributive effects of bilinear tax reforms that are applied to dual income taxes or, more generally, to two different one-dimensional taxes. To do so we analyze the one-dimensional income tax case, and then we introduce a partial order, based on the Lorenz dominance criterion, which induces a lattice structure within the set of bilinear tax reforms whenever certain conditions on the tax reform policies and the dual inc…
