A characterization of random min–max domains and its applications

S Roy, S Sadhukhan - Economic Theory, 2019 - Springer
We show that a random rule on a top-connected single-peaked domain is unanimous and
strategy-proof if and only if it is a random min–max rule. As a by-product of this result, it …

Treading a fine line:(im) possibilities for Nash implementation with partially-honest individuals

M Lombardi, N Yoshihara - Games and Economic Behavior, 2018 - Elsevier
This paper investigates the robustness of Dutta and Sen's (2012) Theorem 1 to weaker
notions of truth-telling. It models individual i's honesty standard as a profile of (possibly non …

Implementation with a sympathizer

OA Altun, M Barlo, NA Dalkıran - Mathematical Social Sciences, 2023 - Elsevier
We study Nash implementation under complete information with the distinctive feature that
the planner knows neither individuals' state-contingent preferences (payoff states) nor how …

On single-peaked domains and min–max rules

G Achuthankutty, S Roy - Social Choice and Welfare, 2018 - Springer
We consider social choice problems where the admissible set of preferences of each agent
is single-peaked. First, we show that if all the agents have the same admissible set of …

Partially-honest Nash implementation: a full characterization

M Lombardi, N Yoshihara - Economic Theory, 2020 - Springer
A partially-honest individual is a person who follows the maxim,“Do not lie if you do not have
to”, to serve your material interest. By assuming that the mechanism designer knows that …

A characterization of possibility domains in strategic voting

S Roy, T Storcken - Journal of Mathematical Economics, 2019 - Elsevier
We consider domains in strategic voting problems which satisfy three properties, namely top-
connectedness, pervasiveness, and richness. We prove the following two results for such a …

[HTML][HTML] Strong implementation with partially honest individuals

F Savva - Journal of Mathematical Economics, 2018 - Elsevier
In this paper we provide sufficient conditions for a social choice rule to be implementable in
strong Nash equilibrium in the presence of partially honest agents, that is, agents who break …

Natural implementation with semi-responsible agents in pure exchange economies

M Lombardi, N Yoshihara - International Journal of Game Theory, 2017 - Springer
We study Nash implementation by natural price–quantity mechanisms in pure exchange
economies when agents have intrinsic preferences for responsibility. An agent has an …

Epistemological implementation of social choice functions

H Matsushima - Games and Economic Behavior, 2022 - Elsevier
We investigate the implementation of social choice functions (SCFs) from an epistemological
perspective. We consider the possibility that in higher-order beliefs there exists an honest …

A unified characterization of the randomized strategy-proof rules

S Roy, S Sadhukhan - Journal of Economic Theory, 2021 - Elsevier
We show that a large class of restricted domains such as single-peaked, single-crossing,
single-dipped, tree-single-peaked with top-set along a path, Euclidean, multi-peaked …
