Auction design with heterogeneous priors Games Econ. Behav. (IF 1.265) Pub Date : 2024-04-10 Hien Pham, Takuro Yamashita
We consider an auction design problem with private values, where the seller and bidders may enjoy heterogeneous priors about their (possibly correlated) valuations. Each bidder forms an (interim) belief about the others based on his own prior updated by observing his own value. If the seller faces uncertainty about the bidders' priors, even if he knows that the bidders' priors are within any given

Maximal Condorcet domains a further progress report Games Econ. Behav. (IF 1.265) Pub Date : 2024-04-09 Clemens Puppe, Arkadii Slinko
Condorcet domains are sets of preference orders such that the majority relation corresponding to any profile of preferences from the domain is acyclic. The best known examples in economics are the single-peaked, the single-crossing, and the group separable domains. We survey the latest developments in the area since Monjardet's magisterial overview (2009), provide some new results and offer two conjectures

Information flows and memory in games Games Econ. Behav. (IF 1.265) Pub Date : 2024-04-03 Pierpaolo Battigalli, Nicolò Generoso
The standard extensive-form partitional representation of information in sequential games fails to distinguish the description of the rules of interaction from the description of players' personal traits. Indeed, this representation does not model how the information given to players as per the rules of the game blends with players' cognitive abilities. We propose a representation of sequential games

Experimental evidence on the relationship between perceived ambiguity and likelihood insensitivity Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-29 Luca Henkel
Observed individual behavior in the presence of ambiguity shows insufficient responsiveness to changes in subjective likelihoods. Despite being integral to theoretical models and relevant in many domains, evidence on the causes and determining factors of such likelihood insensitive behavior is scarce. This paper investigates the role of beliefs in the form of ambiguity perception – the extent to which

Collusion-proof mechanisms for full surplus extraction Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-28 Huiyi Guo
The paper examines information structures that can guarantee full surplus extraction via collusion-proof mechanisms. Our collusion-proofness notion requires that there does not exist any coalition whose manipulation can affect the mechanism designer's payoff. When the mechanism designer is restricted to using standard Bayesian mechanisms, we show that under almost every prior distribution of agents'

Myopic oligopoly pricing Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-27 Iwan Bos, Marco A. Marini, Riccardo D. Saulle
This paper examines capacity-constrained oligopoly pricing with sellers who seek myopic improvements. We employ the Myopic Stable Set solution concept and establish the existence of a unique pure-strategy price solution for any given level of capacity. This solution is shown to coincide with the set of pure-strategy Nash equilibria when capacities are large or small. For an intermediate range of capacities

Strong core and Pareto-optimality in the multiple partners matching problem under lexicographic preference domains Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-26 Péter Biró, Gergely Csáji
We study strong core and Pareto-optimal solutions for multiple partners matching problem under lexicographic preference domains from a computational point of view. The restriction to the two-sided case is called stable many-to-many matching problem and the general one-sided case is called stable fixtures problem. We provide an example to show that the strong core can be empty even for many-to-many

Information avoidance in school choice Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-25 Paola Moscariello
I explain puzzles in the school assignment literature using a many-to-one matching model in which participants on one side of the market, the students, are endowed with ego-utilities à la (). Ego concerns generate a form of information avoidance that results in non-truthful participation in DA matching mechanisms. In particular, students' best replies may be non-monotonic in school ranks. I show that

Relative performance evaluation in spillover networks Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-25 Yang Sun, Wei Zhao
In a multi-agent contracting problem, agents are linked in performance through two channels, effort spillover, governed by spillover network, and risk correlation, governed by risk structure. Assigning compensation weights on peers' performances can not only filter out common risks but also alter agent's incentives. We study how the network and risk structure jointly determine the optimal linear contract

Efficient matching under general constraints Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-25 Kenzo Imamura, Yasushi Kawase
We study indivisible goods allocation problems under constraints and provide algorithms to check whether a given matching is Pareto efficient. We first show that the serial dictatorship algorithm can be used to check Pareto efficiency if the constraints are matroid. To prove this, we develop a generalized top trading cycles algorithm. Moreover, we show that the matroid structure is necessary for obtaining

Best-response dynamics in two-person random games with correlated payoffs Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-25 Hlafo Alfie Mimun, Matteo Quattropani, Marco Scarsini
We consider finite two-player normal form games with random payoffs. Player A's payoffs are i.i.d. from a uniform distribution. Given , for any action profile, player B's payoff coincides with player A's payoff with probability and is i.i.d. from the same uniform distribution with probability . This model interpolates the model of i.i.d. random payoff used in most of the literature and the model of

Voting to persuade Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-24 Tsz-Ning Wong, Lily Ling Yang, Xin Zhao
We consider a model of collective persuasion, in which members of an advisory committee with private continuous signals vote on a policy change. A decision maker then decides whether to adopt the change upon observing each vote. Information transmission between the committee and the decision maker is possible if and only if there exists an informative equilibrium in which the decision maker only adopts

Hidden in plain sight: Payoffs, probability, space, and time in isomorphic tasks Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-21 Sean M. Collins, Duncan James
Highest stoppage games in economics—first price sealed bid auction and Dutch auction, among others—have produced striking puzzles, including violation of revenue equivalence between auctions and adjustment of behavior across interfaces. The latter is also observed in risk elicitation. Here, we use existing puzzles to shed light on each other, by nesting auction and risk tasks in a common environment

Bayesian stable states Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-21 Yi-Chun Chen, Gaoji Hu
This paper extends the Bayesian stability notion of to define the Bayesian stability of a , which consists of a matching outcome and an information structure. The information structure can be arbitrarily heterogeneous and can accommodate learning among agents. We first establish that a Bayesian stable matching function of can be recast as Bayesian stable market states with homogeneous information.

Entry under placement uncertainty Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-20 Sunanda Roy, Rajesh Singh, Quinn Weninger
We present a model of firm entry in an industry that operates under an aggregate production quota or cap-and-trade (CAT) regulation. Firms are heterogeneous in their own productivity; each knows its costs of production but is uncertain about where its costs rank among an entrant population. We show the existence of a unique, symmetric, dominance solvable, Bayesian Nash equilibrium in switching strategies

Quantal response equilibrium and rationalizability: Inside the black box Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-19 Shuige Liu, Fabio Maccheroni
This paper aims to connect epistemic and behavioral game theory by examining the epistemic foundations of quantal response equilibrium (QRE) in static games. We focus on how much information agents possess about the probability distributions of idiosyncratic payoff shocks, in addition to the standard assumptions of rationality and common belief in rationality. When these distributions are transparent

On common evaluation standards and the acceptance of wage inequality Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-16 Peter Werner
This study investigates how the exogenous provision of norm information concerning wage inequality influences the acceptance of wage differences. In an experiment where one employer interacts with two employees who differ in productivities, two main treatments provide information suggesting either an injunctive norm for small or for large wage differences prior to the interaction.

Efficiency wages with motivated agents Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-16 Jesper Armouti-Hansen, Lea Cassar, Anna Deréky, Florian Engl
Many jobs serve a social purpose beyond profit maximization, contributing positively to society. This paper uses a modified principal-agent gift-exchange game with positive externality (prosocial treatment) to study how workers' prosocial motivation interacts with the use of efficiency wages in stimulating effort. We find that prosocial motivation and efficiency wages are independent in stimulating

Equilibrium information in credence goods Games Econ. Behav. (IF 1.265) Pub Date : 2024-03-15 Ting Liu, Ching-to Albert Ma
We study credence goods in a general model. A consumer may suffer a loss which is a continuous random variable. Privately observing the loss value, an expert can provide a repair at a price to eliminate the consumer's loss. All perfect-Bayesian equilibria are inefficient, in that some losses are not repaired. In closed form, we derive a pooling equilibrium (where losses are inferred to be in an interval)

Simple relational contracts and the dynamics of social capital Games Econ. Behav. (IF 1.265) Pub Date : 2024-02-28 M, a, t, h, i, e, u, , V, ., , L, e, d, u, c
This article proposes a dynamic model to examine the structure of “simple” relational contracts, obeying realistic properties that can be easily understood and audited by both parties. In such relationships, the need to offer each supplier a large enough share of future business to deter cheating limits the number of relationships a buyer can sustain. Trade is thus restricted to durable relationships

Two experiments on trading information goods in a network Games Econ. Behav. (IF 1.265) Pub Date : 2024-02-23 Nobuyuki Hanaki, Yutaka Kayaba, Jun Maekawa, Hitoshi Matsushima
We examine the impact of a cycle path on the trading of a copyable information good in a network experimentally. A cycle path in a network allows a buyer to become a reseller who can compete against existing sellers by replicating the good. A theoretical prediction considers that the price of the information good, even with the first transaction where there is not yet a reseller competing with the

Optimal auction design with aftermarket Cournot competition Games Econ. Behav. (IF 1.265) Pub Date : 2024-02-23 Yanlin Chen, Audrey Hu, Jun Zhang
We study an optimal information/mechanism design problem for selling an object to a number of asymmetric, privately informed bidders in which the winning bidder competes with a third party under differentiated Cournot competition afterwards. We show how to decompose the problem into two sub-problems: Bayesian persuasion and standard mechanism design. Full disclosure of the winner's marginal cost emerges

An undecidable statement regarding zero-sum games Games Econ. Behav. (IF 1.265) Pub Date : 2024-02-22 Mark Fey
In this paper, we give an example of a statement concerning two-player zero-sum games which is undecidable, meaning that it can neither be proven or disproven by the standard axioms of mathematics. Earlier work has shown that there exist “paradoxical” two-player zero-sum games with unbounded payoffs, in which a standard calculation of the two players' expected utilities of a mixed strategy profile

Pork barrel politics, voter turnout, and inequality: An experimental study Games Econ. Behav. (IF 1.265) Pub Date : 2024-02-21 Jens Großer, Thorsten Giertz
We experimentally study pork barrel politics in repeated two-candidate majoritarian elections with costly voting. Candidates form distinct supporter groups by favoring some voters in budget spending and ignoring others. Relative to compulsory voting, voluntary voting induces on average larger, more narrowly targeted favors and therefore more inequality among otherwise identical voters. Against our

Multi-dimensional reasoning in competitive resource allocation games: Evidence from intra-team communication Games Econ. Behav. (IF 1.265) Pub Date : 2024-02-10 Ayala Arad, Stefan P. Penczynski
We experimentally investigate behavior and reasoning in various competitive resource allocation games with large strategy spaces. In the experiment, a team of two players plays as one entity against other teams. Team members communicate with one another before choosing a strategy. We analyze their messages using three different classification approaches and find that the vast majority of players think

The impact of fraud on reputation systems Games Econ. Behav. (IF 1.265) Pub Date : 2024-02-09 Jan Philipp Krügel, Fabian Paetzel
Reputation systems can mitigate opportunistic behavior and improve efficiency on online marketplaces. However, rating fraud is a major problem on many websites. We experimentally investigate the circumstances under which rating fraud undermines the functioning of a reputation system and reduces efficiency. We find that the ability to manipulate feedback received from others generally reduces the reliability

Popular matchings with weighted voters Games Econ. Behav. (IF 1.265) Pub Date : 2024-02-07 Klaus Heeger, Ágnes Cseh
We consider a natural generalization of the well-known problem where every vertex has a weight. We call a matching more popular than matching if the weight of vertices preferring to is larger than the weight of vertices preferring to . For this case, we show that it is -hard to find a popular matching. Our main result is a polynomial-time algorithm that delivers a popular matching or a proof for its

Information disclosure in mitigating moral hazard: An experimental investigation Games Econ. Behav. (IF 1.265) Pub Date : 2024-02-07 Ninghua Du, Quazi Shahriar
In a moral hazard framework, an agent considers undertaking a task of uncertain difficulty. An of the task's difficulty by the principal convinces the agent to perform only easy tasks. By contrast, information design theory predicts that can induce the agent to continue working even when the work turns out to be challenging. Our experimental evidence confirms that delayed disclosure outperforms immediate

Learning in networks with idiosyncratic agents Games Econ. Behav. (IF 1.265) Pub Date : 2024-02-06 Vatsal Khandelwal
Individuals update their beliefs and respond to new information in idiosyncratic ways. I show that an individual's idiosyncrasies such as under-reaction, over-reaction, or frustration can have spillover effects and adversely affect the long run beliefs of society. I derive sufficient conditions for convergence of beliefs for all possible networks of agents with heterogeneous idiosyncrasies. Beliefs

Shining with the stars: Competition, screening, and concern for coworkers' quality Games Econ. Behav. (IF 1.265) Pub Date : 2024-02-06 Francesca Barigozzi, Helmuth Cremer
We study how workers' concern for coworkers' ability (CfCA) affects competition in the labor market. Two firms offer nonlinear contracts to a unit mass of prospective workers. Firms may differ in their marginal productivity, while workers are heterogeneous in their ability (high or low) and their taste for being employed by any of the two firms. Workers receive a utility premium when employed by the

Beyond dominance and Nash: Ranking equilibria by critical mass Games Econ. Behav. (IF 1.265) Pub Date : 2024-02-05 Adam Tauman Kalai, Ehud Kalai
Strategic interactions pose central issues that are not adequately explained by the traditional concepts of dominant strategy equilibrium (DSE), Nash equilibrium (NE), and their refinements. A comprehensive analysis of equilibrium concepts within the von Neumann-Nash framework of -person optimization reveals a decreasing hierarchy of nested concepts ranging from DSE to NE. These concepts are defined

Impartial selection with additive guarantees via iterated deletion Games Econ. Behav. (IF 1.265) Pub Date : 2024-02-01 Javier Cembrano, Felix Fischer, David Hannon, Max Klimm
Impartial selection is the selection of an individual from a group based on nominations by other members of the group, in such a way that individuals cannot influence their own chance of selection. For this problem, we give a deterministic mechanism with an additive performance guarantee of in a setting with individuals where each individual casts nominations, where . This bound is for and for . The

Dynamic coordination with payoff and informational externalities Games Econ. Behav. (IF 1.265) Pub Date : 2024-01-19 Beixi Zhou
I study a two-player continuous-time dynamic coordination game with observational learning. Each player has one opportunity to make a reversible investment with an uncertain return that is realized only when both players invest. Each player learns about the potential return by observing a private signal and the actions of the other player. In equilibrium, players' roles as leader and follower are endogenously

Partnerships based on Joint Ownership Games Econ. Behav. (IF 1.265) Pub Date : 2024-01-19 Matthias Blonski, Daniel Herbold
In a unifying framework generalizing established theories we characterize under which conditions Joint Ownership of assets creates the best cooperation incentives in a partnership. We endogenise renegotiation costs and assume that they weakly increase with additional assets. A salient sufficient condition for optimal cooperation incentives among patient partners is if Joint Ownership is a for which

Queueing games with an endogenous number of machines Games Econ. Behav. (IF 1.265) Pub Date : 2024-01-18 Ata Atay, Christian Trudeau
We study queueing problems with an endogenous number of machines, the novelty being that coalitions not only choose how to queue, but on how many machines. After minimizing the processing costs and machine costs, we share the proceeds of this cooperation, and study the existence of stable allocations. First, we study queueing problems, and examine how to share the total cost. We provide an upper bound

Incomplete preferences or incomplete information? On Rationalizability in games with private values Games Econ. Behav. (IF 1.265) Pub Date : 2024-01-17 Enrico De Magistris
I propose a notion of Rationalizability, called Incomplete Preference Rationalizability, for games with incomplete preferences. Under an appropriate topological condition, the incomplete preference rationalizable set is non-empty and compact. I argue that incomplete orderings can be used to model incomplete information in strategic settings. Drawing on this connection, I show that in games with private

Reinforcement learning in a prisoner's dilemma Games Econ. Behav. (IF 1.265) Pub Date : 2024-01-17 Arthur Dolgopolov
I characterize the outcomes of a class of model-free reinforcement learning algorithms, such as stateless Q-learning, in a prisoner's dilemma. The behavior is studied in the limit as players stop experimenting after sufficiently exploring their options. A closed form relationship between the learning rate and game payoffs reveals whether the players will learn to cooperate or defect. The findings have

Dominated choices under deferred acceptance mechanism: The effect of admission selectivity Games Econ. Behav. (IF 1.265) Pub Date : 2024-01-17 Ran I. Shorrer, Sándor Sóvágó
College applicants often make dominated choices even when a strategically simple mechanism such as deferred acceptance is in place. We study Hungarian college admissions, where deferred acceptance is used, and still many college applicants make revealed dominated choices: they forgo the free opportunity to receive a tuition waiver. Using two empirical strategies, we show that when admission with a

The notion of is a natural and intuitive fairness requirement in resource allocation. With indivisible goods, such fair allocations are not guaranteed to exist. Classical works have avoided this issue by introducing an additional divisible resource, i.e., money. In this paper, we aim to design a truthful allocation mechanism of indivisible goods to achieve fairness and efficiency criteria with a limited

Imposing commitment to rein in overconfidence in learning Games Econ. Behav. (IF 1.265) Pub Date : 2024-01-10 Marcelo Ariel Fernandez, Tatiana Mayskaya, Arina Nikandrova
A rational principal delegates learning to an overconfident agent who overestimates the precision of the information he collects. The principal chooses between two contracts: commitment, in which the agent commits to the duration of learning in advance, and flexible, in which the agent decides when to stop learning in real time. When the agent is sufficiently overconfident, the principal optimally

A stranger in a strange land: Promises and identity Games Econ. Behav. (IF 1.265) Pub Date : 2023-12-23 Gary Charness, Giovanni Di Bartolomeo, Stefano Papa
One's social identity tends to favor those belonging to one's group. At the same time, communication has had beneficial social consequences in controlled laboratory experiments. Can communication improve trust and outcomes between out-group members by making them more familiar? We construct a simple weak mechanism of group favoritism (different assigned colors) that induces in-group favoritism. Communication

Cournot meets Bayes-Nash: A discontinuity in behavior in finitely repeated duopoly games Games Econ. Behav. (IF 1.265) Pub Date : 2023-12-20 Cédric Argenton, Radosveta Ivanova-Stenzel, Wieland Müller
We conduct a series of Cournot duopoly market experiments with a high number of repetitions and fixed matching. Our treatments include markets with (a) complete cost symmetry and complete information, (b) slight cost asymmetry and complete information, and (c) varying cost asymmetries and incomplete information. For the case of complete cost symmetry and complete information, our data confirm the well-known

Cooperation, competition, and welfare in a matching market Games Econ. Behav. (IF 1.265) Pub Date : 2023-12-15 Helmut Bester, József Sákovics
We investigate the welfare effect of increasing competition in an anonymous two–sided matching market, where matched pairs play an infinitely repeated Prisoner's Dilemma. Higher matching efficiency is usually considered detrimental as it creates stronger incentives for defection. We point out, however, that a reduction in matching frictions also increases welfare because more agents find themselves

Independent versus collective expertise Games Econ. Behav. (IF 1.265) Pub Date : 2023-12-12 Emiliano Catonini, Andrey Kurbatov, Sergey Stepanov
We consider the problem of a decision-maker who seeks for advice from several experts. The experts have reputation concerns which generate incentives to herd on the prior belief about the state of the world. We address the following question: Should the experts be allowed to exchange their information before providing advice (“collective expertise”) or not (“independent expertise”)? We show that collective

Coalitional stability in matching problems with externalities and random preferences Games Econ. Behav. (IF 1.265) Pub Date : 2023-12-11 Adriana Piazza, Juan Pablo Torres-Martínez
We study coalitional stability in matching problems with externalities, including marriage markets, roommate problems, and Shapley-Scarf housing markets as particular cases. When preferences are randomly determined, the probability of having a coalitionally stable solution is positively affected by three factors: the prudence of coalitions when evaluating a deviation, the social connectedness of those

Large random matching markets with localized preference structures can exhibit large cores Games Econ. Behav. (IF 1.265) Pub Date : 2023-12-16 Ross Rheingans-Yoo
I present a class of models for random matching markets with non-homogeneous agent preferences, drawn from the computer science literature on network structure. An analogue of the Watts–Strogatz (1998) ‘small-world’ network model supports significant incentives to manipulate matching outcomes. The scope for manipulation remains substantial as markets become large and unbalanced—contrasting prior work

School choice with costly information acquisition Games Econ. Behav. (IF 1.265) Pub Date : 2023-12-01 Tyler Maxey
I study a model of centralized school choice in which students engage in costly search over schools before submitting preference reports to a clearinghouse. I consider three classes of preferences over schools—idiosyncratic, common, and hybrid—and characterize outcomes under two search protocols—simultaneous and sequential. With idiosyncratic preferences, there are no search externalities, and inefficiencies

Reallocation with priorities Games Econ. Behav. (IF 1.265) Pub Date : 2023-12-05 Julien Combe, Jan Christoph Schlegel
We consider a reallocation problem with priorities where each agent is initially endowed with a house and is willing to exchange it but each house has a priority ordering over the agents of the market. In this setting, it is well known that there is no individually rational and stable mechanism. As a result, the literature has introduced a modified stability notion called μ0-stability. In contrast

Order independence for rationalizability Games Econ. Behav. (IF 1.265) Pub Date : 2023-11-29 Julien Manili
This paper provides a sufficient monotonicity condition for the solution of a rationalizability procedure to be independent of the order of elimination. The analysis unfolds in an abstract environment that applies to any game and elimination procedure. Monotonicity is satisfied by rationalizability procedures based on monotone belief operators, such as “directed” rationalizability, interim correlated

Commitment requests do not affect truth-telling in laboratory and online experiments Games Econ. Behav. (IF 1.265) Pub Date : 2023-11-29 Tobias Cagala, Ulrich Glogowsky, Johannes Rincke, Simeon Schudy
Using a standard cheating game, we investigate whether the request to sign a no-cheating declaration affects truth-telling. Our design varies the content of a no-cheating declaration (reference to ethical behavior vs. reference to possible sanctions) and the type of experiment (online vs. offline). Irrespective of the declaration's content, commitment requests do not affect truth-telling, neither in

The groupwise-pivotal referral auction: Core-selecting referral strategy-proof mechanism Games Econ. Behav. (IF 1.265) Pub Date : 2023-11-30 Seungwon (Eugene) Jeong, Joosung Lee
We introduce the groupwise-pivotal referral (GPR) mechanism for auctions where buyers can participate through referrals. Each buyer's type consists of a valuation and referable buyers. Unlike the second-price auction (SPA), the Vickrey-Clarke-Groves (VCG) mechanism provides referral incentives. However, VCG is not budget-feasible. In contrast, under complete information, GPR is core-selecting, implying

Optimal disclosure in all-pay auctions with interdependent valuations Games Econ. Behav. (IF 1.265) Pub Date : 2023-11-30 Bo Chen, Bo Chen
We study all-pay auctions with one-sided private information and interdependent valuations. To sharpen the competition and maximize revenue, the auction organizer can design an information disclosure policy through Bayesian persuasion about the bidder with private information. We characterize optimal disclosure and find that optimal disclosure exhibits almost full disclosure, where the uninformed bidder

Believe it or not: Experimental evidence on sunspot equilibria with social networks Games Econ. Behav. (IF 1.265) Pub Date : 2023-11-30 Pietro Battiston, Sharon G. Harrison
Models with sunspot equilibria have long been a topic of interest among economists. It then became an interesting question to ask whether there is empirical support for their existence. One approach to answer this question is through lab experiments. A growing literature has not only successfully reproduced these equilibria in the lab, but also improved our understanding of the conditions under which

Rejection-proof mechanisms for multi-agent kidney exchange Games Econ. Behav. (IF 1.265) Pub Date : 2023-11-23 Danny Blom, Bart Smeulders, Frits Spieksma
Kidney exchange programs (KEPs) increase kidney transplantation by facilitating the exchange of incompatible donors. Increasing the scale of KEPs leads to more opportunities for transplants. Collaboration between transplant organizations (agents) is thus desirable. As agents are primarily interested in providing transplants for their own patients, collaboration requires balancing individual and common

Obvious manipulations of tops-only voting rules Games Econ. Behav. (IF 1.265) Pub Date : 2023-11-22 R. Pablo Arribillaga, Agustín G. Bonifacio
In a voting problem with a finite set of alternatives to choose from, we study the manipulation of tops-only rules. Since all non-dictatorial (onto) voting rules are manipulable when there are more than two alternatives and all preferences are allowed, we look for rules in which manipulations are not obvious. First, we show that a rule does not have obvious manipulations if and only if when an agent

Designing rotation programs: Limits and possibilities Games Econ. Behav. (IF 1.265) Pub Date : 2023-11-23 Ville Korpela, Michele Lombardi, Riccardo D. Saulle
Rotation programs are widely used in our society. For instance, a job rotation program is an HR strategy where employees rotate between two or more jobs in the same business. We study rotation programs within the standard implementation framework under complete information. We introduce the notion of implementation in ordered cycles, where each ordered cycle is a rotation program for an assignment

The n-player Hirshleifer contest Games Econ. Behav. (IF 1.265) Pub Date : 2023-11-22 Christian Ewerhart, Guang-Zhen Sun
While the game-theoretic analysis of conflict is often based on the assumption of multiplicative noise, additive noise such as considered by Hirshleifer (1989) may be equally plausible depending on the application. In this paper, we examine the equilibrium set of the n-player difference-form contest with heterogeneous valuations. For high and intermediate levels of noise, the equilibrium is in pure
