l 題目 The effect of strategic environment and group size in beauty contest games
(with Angela Sutan and Marc Willinger)

 

l 概要: Does the effect of strategic environments (strategic substitution v.s.
strategic complement) on the experimental outcomes depend on the size of group?
We investigated this question by varying the group size, 2-player vs
8-player,
in the two versions of beauty contest games with an interior
equilibrium.
We replicate main finding of a previous study that shows
significantly larger
deviations of chosen numbers from the equilibrium
under the strategic
complementarity than under the strategic
substitution for 8-player games.
We found, however, that such a
significant effect of the strategic environment
disappears in 2 player games.

l 題目 How Coarsening Simplifies Matching-Based Causal Inference Theory

l 概要:The simplicity and power of matching methods have made them an increasingly popular approach to causal inference in observational data. Existing theories that justify these techniques are well developed but either require exact matching, which is usually infeasible in practice, or sacrifice some simplicity via asymptotic theory, specialized bias corrections, and novel variance estimators; and extensions to approximate matching with multicategory treatments have not yet appeared. As an additional option for researchers, we show how conceptualizing continuous variables as having logical breakpoints (such as phase transitions when measuring temperature or high school or college degrees in years of education) is both natural substantively and can be used in some applications to construct a relatively simple theory of causal inference. The result is a finite sample theory that is simple to understand and easy to implement by using matching to preprocess the data, after which one can use whatever method would have been applied without matching. The theoretical simplicity also allows for binary, multicategory, and continuous treatment variables from the start and for extensions to valid inference under imperfect treatment assignment. In applications where the existing theory of matching is difficult to apply, the new approach added to the existing toolkit may help some researchers in these situations make valid causal inferences, or at least better understand why they cannot.

l 題目 Other-regarding behavior under collective action

l 概要:In many collective action settings, such as decisions on public education or climate change mitigation, actions of a group have welfare consequences for themselves as well as their followers. We conduct laboratory experiments with two-stage predecessor-follower prisoners' dilemma and coordination games with dynamic externalities to study whether concerns for the followers' welfare affect the predecessors' behavior. We find that predecessors often give up own payoffs to avoid imposing negative externalities on the followers, but not to generate positive externalities for the followers. A concern for the followers aligned with own group payoff maximization motive helps to resolve socialdilemma and coordination problems; yet, a conffict in motives greatly exacerbates both free-riding and coordination on the payoff-inferior equilibrium. We also find strong evidence of social learning: the followers tend to blindly mimic their own predecessor, but act opposite to their match's predecessor, no matter whether these actions are welfare-improving or not.

l 題目 EXITING FROM QE

l 概要:We develop a regime-switching SVAR (structural vector autoregression) in which the monetary policy regime, chosen by the central bank responding to economic conditions, is endogenous and observable. There are two regimes, one of which is QE (quantitative easing). The model can incorporate the exit condition for terminating QE. We then apply the model to Japan, a country that has accumulated, by our count, 130 months of QE as of December 2012. Our impulse response and counter-factual analyses yield two findings about QE. First, an increase in reserves raises inflation and output. Second, terminating QE can be expansionary.

l 題目 A Non-cooperative Bargaining Theory with Incomplete Information: Verifiable Types

l 概要: We consider a non-cooperative two-person sequential bargaining game with incomplete
information. Player types are verifiable when a contract is implemented. We show that there
is no delay in agreements and the inscrutability principle holds under the property of independence
of irrelevant types (IIT), whereby the response of every type of player is independent of proposals
to other player types. We prove the existence of a stationary sequential equilibrium satisfying IIT
and a self-selection property for every discount factor for future payoffs. We also show that the
equilibrium proposal of every player converges to the ex post Nash bargaining solution as the
discount factor goes to one.

l 題目 Comparable Characterizations of Four Values for Permission Tree Games
(joint work with Chris Dietz, Gerard van der Laan and Genjiu Xu)

 

l 概要: In the field of cooperative games there is an extensive literature that studies situations of restricted cooperation. Myerson (1979) introduced communication graph games, where players can only cooperate if they are connected in an undirected graph representing the communication possibilities. The Myerson value of such a game is obtained by taking the Shapley value of the corresponding restricted game. For the special case that the graph is cycle-free and connected, Demange (2004) introduced for each player the corresponding hierarchical outcome, being the marginal contribution vector for a particular permutation of the player set induced by the graph. Gilles, Owen and van den Brink (1992) introduced games with a (hierarchical) permission structure modeled by a directed graph on the set of players. In the conjunctive (disjunctive) approach, a coalition is said to be feasible, if for every player in the coalition also all (at least one of) its predecessors (if any) belong(s) to the coalition. The conjunctive (disjunctive) permission value is obtained by taking the Shapley value of the associated conjunctive (disjunctive) restricted game. The two approaches coincide when the permission structure is given by a rooted tree.
       In this paper we consider games with a hierarchical permission structure given by a rooted tree and modify the Myerson value to a value for such games. We also consider for these games the hierarchical outcome with respect to the root of the tree (top player), along with a new solution that assigns all payoff to the unique top player in the hierarchy. Then comparable characterizations are given of these three solutions and the (conjunctive) permission value.

l 題目 Dynamic Noncooperative Group Formation with Size Advantage and Group Reputation

l Extended Abstract analyze a noncooperative dynamic game of group formation with group reputation. It is inspired by observations of ``name adoption" patterns in some retail markets. Suppose that a market can sustain N firms.  Firms are partitioned into name groups, or affiliation networks.  In a group, all firms share the same group reputation among consumers. If a firm fails, an entrant firm chooses which name to adopt or to create a new name. There is no cost of choosing any name, but group size and history matter. Joining a larger group has an advantage of non-linearly increasing rate of choice by consumers, but has a disadvantage of higher rate of future failure within the group. Reputation information is endogenous and imperfect in the sense that consumers observe failure of a firm only in the group that they patronized in the current period.   Firms stay in the game until it fails stochastically (e.g., due to imperfect monitoring), and a small fraction of consumers exit the game for an exogenous cause (death, moving etc.) each period.  Newcomer consumers do not have information about group histories and thus choose firm groups randomly but favor larger groups over smaller groups.  The non-linear likelihood of group choice is formulated by Lanchester's Square Law (Lanchester, 1916). Existing firms (groups) cannot reject an entering firm's adoption of the name. (This is the case for categorical names: for the retail industry, various cooperative names exist in the same place, e.g., cooperatives, savings association, and trade association. For the banking industry, credit union, thrift, and savings and loan association can be used for the same type of business.)  For simplicity, there is no explicit interaction among firms in the same group (unlike industrial organization literature of collusion, joint ventures etc.), nor network structure choice by the firms.  An entering firm determines the group size distribution of that period, but it changes over time by stochastic failure and later entrants. We consider firms' optimization over uncertain horizon, instead of (myopic) best-response dynamic (Bala and Goyal, 2000) or finitely repeated social game (e.g., Jackson and Watts, 2010). Empirical patterns have synergy effects as follows.  If a name group has a failure, it is less likely that the tainted name gets adopted soon afterwards. If a name is created/joined by a new firm, then it is more likely that the same name is adopted afterwards. Other facts include that new names are more likely to be created when there is no untainted group. We found that even if the tainted name group was the universal group (all firms having the same name), creating a new name is better than joining the tainted but dominant group, when consumer turnover rate is small, confirming the first pattern. (Hence the universal connected network is not absorbing.)  In addition, if the failure rate is sufficiently small, the dynamic process of group structure is recurrent among two group partitions and the universal group.  This is because a new name is created after a failure in the universal group, but one of the two groups grows afterwards, back to the universal group.  New name creation does not occur when there is an untainted name group to join. These are consistent with the second and third pattern.

l 題目 Behavioral Approach to Repeated Games with Private Monitoring

l 概要:We examine repeated prisoners’ dilemma with imperfect private monitoring and random termination where the termination probability is low. We run laboratory experiments and show subjects retaliate more severely when monitoring is more accurate. This experimental result contradicts the prediction of standard game theory. Instead of assuming full rationality and pure self-interest, we introduce naiveté and social preferences, i.e., reciprocal concerns, and develop a model that is consistent with, and uniquely predicts, the observed behavior in the experiments. Our behavioral model suggests there is a trade-off between naiveté and reciprocity. When people are concerned about reciprocity, they tend to make fewer random choices.

l 報告題: Naivete and sophistication in dynamic inconsistency

l 共著者: Janos Flesch, Zsombor Z. Meder and Ronald Peeters

l 概要:This paper introduces a general framework for dealing with dynamic inconsistency in the context of Markov decision problems. It carefully decouples and examines concepts that are often entwined in the literature: it distinguishes between the decision maker and its various temporal agents, and between the beliefs and intentions of the agents. Classical examples naivete and sophisticattion are modeled and contrasted based on this new language. We show that naive and sophisticated decision makers can form optimal strategies at each possible history, and provide comparisons of well-being for a class of decision problems including procrastination, impulsiveness, underinvestment, binges and indulgence. The creation of a unified formalism to deal with dynamic inconsistency allows for the introduction of a hybrid type of decision maker, who is naive in some states and sophisticated in others. Such a hybrid type can be used to model situations which were inaccessible with previous approaches. Interestingly, the analysis of hybrid types indicates that self-deception can be optimal like in the indulgence problem.

l 報告題:Punishment Patterns (joint work with Sebastian Kube, Christian Traxler)

l 概要:This paper studies patterns of punishment in a one-shot public goods game. Building upon a novel strategy-method approach at the punishment  stage of the game, we classify individual punishment patterns. We find that almost 40% of the subjects never engage in punishment. Among those who punish, the vast majority displays a clear pro-social pattern of punishment. Employing a within-subject design, we then compare these punishment patterns with conditional contribution patterns. This allows us to analyze two-dimensional type classifications. Our data indicate high frequencies of consistenttypes: conditional cooperators that punish pro-socially as well as free-riders that never punish. However, the analysis also reveals a non-negligible share of free-riders that punish and conditional cooperators that do not engage in punishment.

l 報告題: Interpersonal Comparison Necessary for Arrovian Aggregation

l 概要:While studies of social welfare functional have revealed that some interpersonal comparability, such as ordinal and level comparability and cardinal and unit comparability, resolves Arrow's impossibility result, we have not known yet what kind of information is necessary to resolve it. The purpose of this paper is to capture the feature of informational structures which make social welfare functionals satisfying Strong Pareto, Anonymity and Independence of Irrelevant Alternatives available. To do so, we provide a characterization of such informational structures. We know from this characterization that if utility levels are not interpersonally comparable, then transformed utility functions by a certain transformation need to be cardinal and unit comparable

l 題目 Hierarchical Agglomeration Bonus for Private Land Conservation

l 概要: Voluntary incentive schemes have been increasingly used in recent years for biodiversity conservation on private land.  However, landowners voluntary decision results in small fragmented reserves, which can cause species extinction.  We propose a hierarchical agglomeration bonus (HAB) mechanism to create incentives for agents in a hierarchical spatial structure to promote local-level coordination. Our HAB mechanism allocates an agglomeration bonus (AB) payment between a local-level bonus rewarding successful local-level coordination and a global-level bonus rewarding successful global-level coordination.   In addition to payoff- and risk-dominant equilibria, Pareto-ranked Nash equilibria can arise in our HAB coordination game, which can facilitate and maintain local-level coordination.   We conducted a laboratory experiment to explore the performance of the HAB mechanism for a hierarchical spatial structure where three local communities of three individuals are nested in a larger global community.   The results show that allocating a higher portion of the total AB to local-level bonuses sharply reduces coordination failure and facilitates a consensus on selecting the payoff dominant strategy at the local community level, leading to a larger-scale, global community level successful coordination.  The results suggest that the locally weighted HAB scheme can contribute to habitat connectivity as well as successful global coordination.

·         題目:Anti-bullying School Choice Mechanism Design

·         概要:The market design approach to school choice has uncovered the desirable properties of the popular mechanisms. However, an educational concern for peer effects, especially the implication of the bullying problems on student assignment has escaped due notice in the literature. This paper first proposes a new framework to study the bullying problems together with school choice. Then it shows that the suitably modified variants of these popular mechanisms have the anti-bullying property (i.e., they systematically separate bullies from their victims, and assign a less preferable school seat to a student if she is involved in an additional bullying episode as a bully) together with other standard desiderata. Finally, by investigating the complementary roles of the market design and anti-bullying program, I discuss the interwoven future perspective of the collaboration between the two fields.

·         題目:"How to Add Apples and Pears: Non-Symmetric Nash Bargaining and the Generalized Joint Surplus" (joint with Samuel Danthine)

·       概要:We generalize the equivalence of the non-symmetric Nash bargaining solution and the linear division of the joint surplus when bargainers use different utility scales. This equivalence in the general case requires the surplus each agent receives to be expressed in compatible, or comparable, units. This result is valid in the case of bargaining over multiple-issues. Our conclusions have important implications for comparative static exercises and calibrated work. For example, when comparing the joint surplus of economies with different preferences, it is crucial to lay out the surplus in terms of one utility unit or the other. On the other hand, while it is necessary to transform the units when expressing the non-symmetric Nash bargaining solution as a share of the joint surplus, it is not necessary to perform a unit transformation when maximizing directly the generalized Nash product. Finally, we discuss the requirements on the curvatures of the agentsutility functions, or, in other words, on the bargainersattitudes towards risk.

·         概要:This study investigates identification of parameters in the semiparametric binary choice models when there are nonignorable nonresponses. We propose an estimation procedure for the identified set of parameters based on the special regressor approach, Lewbel (2000). We show that the estimator for the identified set is consistent in the Hausdorff metric. To demonstrate the availability of the proposed methodology, we present an empirical case study consisting of an economic valuation of a landscape with a dichotomous choice contingent valuation.

·         題目:Guilt Aversion and Peer Information in Crime: Evidence from Experiment and Survey Data in a Developing Country

·         概要:It has been discussed that the existence of peer effect causes the disparity in criminal incidence, but few studies examine how it occurs. I conduct an artefactual field experiment in rural Bangladesh with randomly sampled participants to identify what causes the peer effects. Particularly, I test two channels based on the guilt aversion preference; through the change in guilt sensitivity and the second order belief. A novel contribution of this experiment is that it elicits the guilt sensitivity at the individual level. I find that the patterns of criminal behavior are consistent with the guilt aversion rather than the altruism and trustworthiness; participants with higher guilt sensitivity and/or lower second order belief are less likely to commit crime. The peer effect occurs through the changes in the second order belief; when crime is common, individuals anticipate that the others expect higher risk of crime victimization, which in turn declines the guilt from committing crime. By using the survey data collected from the same participant households, I show the validity of the elicited guilt sensitivity; individuals are less likely to experience crime victimization in the villages where villagers have higher guilt sensitivity.

·         題目:The Boy who Cried Bubble: Public Warnings against Riding Bubble (with Kozo Ueda),

·         概要:Governments seemed unsuccessful in their attempts to stop bubbles through the use of warnings. This paper examines the effects of public warnings using a simple model of riding bubbles. We show that public warnings against a bubble can stop it if investors believe that the government issues such warnings only after bubbles start. Moreover, the bubble may crash before the warning. If there is the possibility that the government issues a warning even though bubble does not occur, then warnings cannot stop the bubble immediately. Our model suggests that, for public warnings, it is not type-II errors but rather type-I errors that are important in preventing bubbles. Public warnings are effective when they provide information to less-informed investors.

囚人のジレンマにおける協力の選択に対する非協力探知型情報構造の効果についての実験的研究

·         日時:2011103() 1630分から1800

·         題目:Political Economy Field Experiments Become Possible.

·         概要:An important part of a field experiment measuring the effectiveness of a proposed policy (social, environmental, public god provision, etc.) would be to gather information about its allocative efficiency.  Efficiency measures are a standard part of lab experiments in economics.  The talk will explain how efficiency is measured in the lab, why that method cannot be used in the field, and propose a new definition and new method that would allow observing allocative efficiency in the field. Initial demonstrations of the methodology will be discussed.

·         題目:Evolution of preferences, mindsight, and cooperation

·         概要:Even in anonymous one-shot interactions humans often do not behave as if each is maximizing his own payoff while assuming others do the same. This propensity to sidestep the logic of Nash equilibrium and the common knowledge of rationality can lead to more cooperation and economically better outcomes in social dilemma situations. But can such a propensity evolve among self-interested agents?  Taking hints from evolutionary psychology and interpersonal neurobiology, we focus on mindsight, the capability to perceive how another person is disposed to behave.  We model the evolution of preferences and mindsight in a population of self-interested agents living in an environment that requires team production for survival and reproduction. We show that if agents are randomly matched to play a two-agent team production game, preferences and mindsight may evolve, allowing agents to partially overcome the social dilemma within each dyad and produce significantly more than in Nash equilibrium, but not as much as under full cooperation.

·         題目: ヴィクセル型取引ネットワークにおけるエッジワース競争の分析

·         概要:本稿では、経済取引を行う相手がヴィクセル的三角形のネットワーク構造で制約された取引の分析例を示す。この分析は、取引ネットワークに参加する経済主体の人数で分類して進められる。取引主体の人数で分類した分析を通じて、その増加が競争的取引にどのように影響を及ぼすかを明示的に扱う。特に本稿では、経済取引のコア配分の集合の包含関係を通じて競争的取引への影響を検証する。

·         題目:Does Marriage Work as a Savings Commitment Device? :Experimental Evidence from Vietnam

·         概要:We conducted a time discounting experiment with married couples, and examined how time preferences, particularly time inconsistency, affect intrahousehold financial decision making. Our experimental results suggest people are more patient when they make decisions jointly with their spouses. The analysis of survey data shows time-inconsistent individuals turn over smaller percentages of their earnings to their spouses. Time-inconsistent husbands are more likely to keepcash within households compared with time-consistent husbands. Time-inconsistent individuals are given smaller amounts of allowances, but they tend to conceal money to compensate. In addition, time-inconsistent subjects choose not to ask their spouses to keep their experimentalearnings and save it for them in the experiment. This study shows marriage does not function (or may counteract) as a savings commitment device, especially for time-inconsistent individuals. This implies households need external savings commitment devices such as ROSCAs to protect money from spouses who have hyperbolic preferences.

·         題目:Sequential Internet auctions with different ending rules

·         概要:Two ending rules, a soft close and a hard close, exist in Internet auctions. The hard close auction involves a fixed deadline, while the deadline in the soft close auction may be extended if at least one bid is submitted in the final few minutes. Thus, the soft close allows buyers to submit ofter observing the opponents bids even in the last minutes. Ending rules change both the sellers and the buyers’ strategies. In a sequential auction with the soft close, buyers have a stronger incentive to wait for low reserve prices in the future, and a seller chooses lower reserve prices.

·         題目:A Factor Analysis of Transaction Costs in Time Preference Experiments

·         概要:実験により計測された時間選好率が高すぎることは良く知られているが,我々の研究は,時間選好率の計測結果に含まれるバイアスを取り除いて,純粋な時間選好に近いものを計測する試みである.バイアスの要因は時間選好率を測る実験の手法に共通かつ不可避なものである.確実な今すぐの報酬の受けとりと等価な将来報酬を回答させるとき,実験者への報酬の預託コストと後日報酬を受け取るコストがあると考えられる.この2つについて,1回のみの報酬受け取りによる先行研究では区別できなかったが,我々は報酬受取りを2回にしたことで,各要素の分離が可能になり,その結果,より低い時間選好率を得た.

·         題目:囚人のジレンマにおける協力の選択に対する非協力探知型情報構造の効果についての実験的研究

·         概要:囚人のジレンマの利得構造の下で,プレイヤーの先手/後手の手番はランダムに決められ,先手が非協力行動を選択する場合にのみその行動が後手によって観察されるとする.このゲームと通常の囚人のジレンマとの相違は情報構造の違いに帰着する.情報構造がこのように修正された囚人のジレンマを非協力探知型情報構造を持つ囚人のジレンマと呼ぶ.非協力探知型情報構造を持つ囚人のジレンマには,利得構造がある一定の条件を満たすとき,双方のプレイヤーが協力的戦略を選択して協力行動がプレイされるナッシュ均衡が存在する.本研究の目的は,このゲームの協力的戦略の選択比率が,通常の囚人のジレンマの協力的戦略(協力行動)の選択比率に比べて,高いか否かを実験によって検証することにある.実験の結果,理論が示唆する範囲の利得構造において,協力的戦略の選択比率は非協力探知型情報構造を持つ囚人のジレンマで高まることが示される.
