Metacontingência, dilema do prisioneiro e cooperação: efeitos da interação verbal e da forma de apresentação da consequência cultural / Metacontingency, prisoners dilemma, and cooperation: effects of verbal interaction and form of cultural consequence presentation

Sampaio, Angelo Augusto Silva 13 June 2016 (has links)
Em uma metacontingência, respostas de dois ou mais indivíduos interagindo (denominadas um culturante) produzem estímulos (denominados de consequências culturais) capazes de afetar a recorrências daquelas respostas. Resultados de experimentos sobre metacontingência têm sido tratados como demonstrações de um tipo de seleção cultural. Além de sugerir a importância de interações verbais entre participantes, alguns desses experimentos têm empregado tarefas baseadas no dilema do prisioneiro repetido (iterated prisoners dilemma, IPD) interpretando-o, porém, como a programação apenas de contingências operantes. O Experimento 1 avaliou se um IPD com mais de 200 tentativas produziria escolhas cooperativas simultâneas de modo fidedigno e se a interação verbal entre participantes aumentaria a cooperação. 4 quartetos de universitários utilizaram 4 computadores conectados em rede (sem contato visual) e foram expostos a condições com ou sem permissão para usar uma sala de bate-papo pelo computador (chat) em um delineamento de linhas de base múltiplas entre quartetos. Os resultados demonstraram claramente que escolhas cooperativas unânimes podem ocorrer fidedignamente em um IPD e que a interação verbal entre participantes aumenta rapidamente tais escolhas. Esses resultados destacam a semelhança entre estudos sobre IPD e sobre metacontingências, nos quais são programadas consequências para comportamentos inter-relacionados de vários indivíduos. No Experimento 2, uma consequência cultural foi sobreposta às consequências já programadas pelo IPD: os quartetos podiam produzir pontos iguais para todos os participantes (feedback do mercado) contingentes a diferentes números de escolhas cooperativas. Como no Experimento 1, condições nas quais o uso do chat eram ou não permitidos foram arranjadas em um delineamento de linhas de base múltiplas entre quartetos. A interação verbal promoveu rápida e marcadamente a seleção cultural pelo feedback do mercado. Um quarteto apresentou algum controle dos culturantes pelo feedback do mercado antes das interações verbais, mas após o uso do chat a produção das consequências culturais aumentou substancialmente. O Experimento 3 replicou o Experimento 2 apresentando o feedback do mercado da mesma forma que os pontos do IPD, i.e., sem diversos estímulos verbais que sugerem a sua produção pelo quarteto como um todo. A interação verbal promoveu ao menos algum controle das escolhas pelo feedback do mercado em 2 dos 3 quartetos, sugerindo que a forma de apresentação da consequência cultural é irrelevante para os efeitos de uma consequência cultural. Os resultados dos 3 experimentos destacam a importância da interação verbal para a seleção cultural. Além disso, sugerem que um IPD programa uma situação análoga à programada em estudos sobre metacontingência, esclarecendo as diferenças entre os procedimentos empregados no estudo do IPD e de metacontingências e permitindo que avanços em uma área possam ser aproveitados pela outra / In a metacontingency, responses of two or more interacting individuals (a culturant) produce stimuli (called cultural consequences) that affect the recurrence of those responses. Results of metacontingency experiments are said to demonstrate a kind of cultural selection. Besides suggesting the importance of verbal interactions between participants, some of these experiments have used tasks based on the iterated prisoner\'s dilemma (IPD) interpreting it, however, as programming only operant contingencies. Experiment 1 examined whether an IPD with 200-plus trials would produce simultaneous cooperative choices reliably and whether verbal interaction between participants would increase cooperation. 4 quartets of undergraduate and graduate students used 4 networked computers (without visual contact), and were exposed to conditions with or without permission to use the computer chat room in a multiple baseline design between quartets. Results clearly demonstrate that unanimous cooperative choices can occur reliably in an IPD, and that verbal interaction between participants rapidly increases such choices. These results highlight the similarity between IPD and metacontingencies studies, both of which program consequences for inter-related behaviors of many individuals. In Experiment 2, a cultural consequence was superimposed on the consequences already programmed by the IPD: quartets could produce equal points for all participants (market feedback) contingent on different numbers of cooperative choices. As in Experiment 1, we arranged conditions in which chat use were or not allowed in a multiple baseline design between quartets. Verbal interaction quickly and markedly promoted cultural selection by the market feedback. One quartet presented some control of culturants by the market feedback before verbal interactions, but production of cultural consequences increased substantially after using the chat. Experiment 3 replicated Experiment 2 presenting the market feedback the same way that the IPD points, i.e., without several verbal stimuli that suggest its production by the quartet as a whole. Verbal interaction promoted at least some control of the choices by the market feedback in 2 of the 3 quartets, suggesting that the form of cultural consequence presentation is irrelevant for the effects of a cultural consequence. The results of the three experiments highlight the importance of verbal interaction for cultural selection. Furthermore, they suggest that an IPD program a situation analogous to the one employed in metacontingency studies, clarifying differences between procedures used in the study of IPD and of metacontingencies, and allowing advances in one area be employed by another

Procedural justice, social norms and conflict : human behavior in resource allocation

Eriksson Giwa, Sebastian January 2009 (has links)
Research questions, results and Empirical Data This book studies the allocation of scarce resources among competing needs and wants. Chapter 1 – Luck, effort and Redistribution on procedural justice provides one possible explanation for the vast differences between US and Western European tax an redistribution levels. Chapter 2- Participation and Peers in Social Dilemmas on social norms investigates two potential reasons why solutions to social dilemmas in for instance insurance systems can persist without being destroyed by the negative forces of free-riding. Chapter 3 - Commitment and Impasses in Negotiation on conflict shifts focus to bilateral bargaining and the reasons for conflict and impasses. Whether they manifest as strikes, job resignations, or trade embargoes, failures of the negotiation process create tremendous loss of social welfare and are therefore important to further understand. Each chapter is based on observations of real human behavior in the lab. The empirical data consists of: 204 M.B.A. students and 96 M.Sc. students from Harvard university, the Stockholm School of Economics, the Royal Institute of Technology, Stockholm university and Karolinska Institutet; 5 experiments over 21 experimental sessions generated 2,520 observations.

Efficacité et acceptabilité de la régulation de la pollution diffuse : expériences sur des variantes coopératives de type « taxe ambiante » / Efficiency and acceptability in the regulation of non-point source pollution : experiments on cooperative ambient-based instruments.

Sarr, Hamet 30 May 2013 (has links)
L’objectif du travail de thèse a été de tester en laboratoire l’efficacité de deux variantes de taxe ambiante (Taxe Pigouvienne Moyenne et Taxe Ambiante Plafonnée) qui présentent l’avantage de réduire les charges en cas de taxation mais dont l’efficacité nécessite que les pollueurs coordonnent leurs efforts. Pour permettre cette coordination, trois formes de communication (communication gratuite ou « cheap talk », communication coûteuse endogène et exogène) ont été testées. Les résultats montrent que le sucker’s payoff et la taille des groupes sont déterminants dans le potentiel du cheap talk à induire de la coopération. Lorsque la communication est coûteuse et exogène, l’impact positif de la communication est limité dans le temps. Cependant lorsque la décision de communiquer moyennant un coût revient aux joueurs, ceux-ci choisissent de ne pas communiquer. Nous avons aussi montré que le cheap talk facilite la coordination vers l’équilibre Pareto-dominant et rend ainsi la Taxe Ambiante Plafonnée efficace. / The purpose of this thesis was to test in laboratory the efficiency of two variants of the ambient tax (Average Pigovian Tax and Capped Ambient Tax) that present the advantage of reducing the financial burden imposed through taxation but whose efficiency requires that polluters coordinate their efforts. To enable this coordination, three types of communication (“cheap talk” or costless communication, exogenous costly communication and endogenous costly communication) are tested.The results show that the sucker’s payoff and the size of the groups are crucial in the potential of cheap talk to induce cooperation. When the communication is costly and exogenous, cooperation is limited in time. However when the decision to communicate for a price is up to the players, they decide not to communicate. We’ve also shown that cheap talk facilitates coordination towards the Pareto-dominant equilibrium and makes the Capped Ambient Tax efficient.

Le rôle des émotions morales dans l'analyse des dilemmes sociaux : la gratitude au coeur des relations entre agents économiques / The role of moral emotions in the analysis of social dilemmas

Jourdheuil, Romain 07 December 2016 (has links)
Cette thèse étudie le rôle des émotions morales dans le choix des agents lorsqu’ils font face à undilemme social. Lors des deux premiers chapitres, nous présentons une revue de littérature étendue, quimobilise des recherches en économie expérimentale, psychologie sociale et gestion des organisations, afin decerner comment les émotions morales, et en particulier la gratitude, influent sur la prise de décision des agentséconomiques. Dans le troisième chapitre, nous nous intéressons, à travers une revue des travaux en économiecomportementale, à l’intégration progressive du rôle des émotions dans les modèles économiques. Nousmontrons ainsi en quoi cette intégration, concomitante à l’apparition des modèles dits de « préférencessociales », permet de représenter de manière plus réaliste le processus de décision des agents, dans dessituations où les comportements économiques observés expérimentalement remettent en cause une visionégoïste et matérialiste des êtres humains. Dans le quatrième chapitre, nous présentons en détail le jeu du bienpublic, ainsi que les principaux résultats expérimentaux qui lui sont associés, pour mieux saisir en quoi ilconstitue un cadre propice à l’analyse formelle de l’influence des émotions morales. Enfin, notre travailaboutit, dans les cinquième et sixième chapitres, à l’élaboration d’un modèle original en économiecomportementale, qui vise à analyser comment l’émergence des émotions morales peut influencer, à la fois enstatique et en dynamique, le choix stratégique des individus dans le jeu du bien public et comment l’ajoutd’une phase de récompense peut renforcer la coopération entre les partenaires / This thesis studies the role of moral emotions in the decision making of agents when they face asocial dilemma. The first two chapters present a large literature review, which gathers research inexperimental economics, in social psychology and in the management of organizations, in order to delineatethe way moral emotions, and specifically gratitude, are able to influence the economical decision process. Inthe third chapter, through a review of works in the field of behavioral economics, we take an interest in theprogressive integration of moral emotions into economic modeling. We thus show how this integration, whichis concurrent with the emergence of social preferences models, allows agents' decision-making processes to berepresented in a more realistic way, in situations where the behaviors that are observed empirically challengean egoistic and materialistic vision of people. In chapter four, the public good game is presented in detail,along with the main experimental results associated with it, in order to understand why this game suits theformal analysis of moral emotions' influence. Finally, our work culminates in the development of an originalmodel in behavioral economics, during chapters five and six, which aims at assessing how the emergence ofmoral emotions can influence, both statically and dynamically, the strategic choice of individuals in the publicgood game, and how the introduction of a reward phase can promote cooperation and help individuals todevelop good interpersonal relationships.

Behövs nya riktlinjer för avfallsutrymmen? : En kvalitativ studie om nya riktlinjer gällande kapacitet på fraktioner till avfallsutrymmen i flerbostadshus / Do we need new guidelines for waste collection areas? : A qualitative study about new guidelines regarding the capacity of fractions within waste collection areas in multi-residential buildings

Wahlgren, Johanna January 2023 (has links)
Det finns många orsaker till att avfall uppkommer, hanteras och sorteras fel. Problemet kan därmed ses från ett antal olika perspektiv. Ett problemområde som identifierats, och som är utgångspunkten i denna studie, är lagstiftningen vad gäller utformningen av avfallsutrymmen vid ny- och ombyggnation. Hade fel hantering och sortering av avfall kunnat förhindras om rätt lagstiftning och rätt förutsättningar för hanteringen fanns på plats? Studiens syfte var att undersöka huruvida det finns ett behov av införandet av nya riktlinjer med krav gällande hur stor kapaciteten på avfallsfraktioner bör vara per flerbostadshus. Frågeställningen som besvarades var: Finns det ett behov av införandet av nya riktlinjer med krav gällande hur stor kapaciteten på avfallsfraktioner bör vara per flerbostadshus vid ny- och ombyggnation av avfallsutrymmen? Semistrukturerade intervjuer utfördes med aktuella aktörer som var inblandade i processen vid ny- och ombyggnation av avfallsutrymmen. Resultatet visade att behovet hos berörda aktörer av att införa nya riktlinjer med krav gällande hur stor kapaciteten på avfallsfraktioner bör vara per flerbostadshus, kan ses som låg då det främst inte uppstår problem för avfallsutrymmena förrän efter att kapaciteten har bestämts. Det visade sig att den främst bakomliggande faktorn till problemet var kommunikationen mellan de olika parterna i processen. / There are many reasons why waste is generated, handled and sorted incorrectly. The problem can therefore be seen from a number of different perspectives. A problem area that has been identified, and which is the starting point of this study, is the legislation regarding the design of waste collection areas during construction and renovation. Could the incorrect handling and sorting have been prevented if the right legislation and the right conditions for handling were in place? The purpose of this study was to investigate whether there is a need for establishing new guidelines with requirements regarding how large the capacity of waste fractions should be per multi-residential building. The question that was answered was: Is there a need for establishing new guidelines with requirements regarding how large the capacity of waste fractions should be per multi-residential building during the construction and renovation of waste collection areas? Semi-structured interviews were conducted with relevant actors who were involved in the process of construction and renovation of waste collection areas. The result showed that the need for relevant actors to establish new guidelines with requirements regarding how large the capacity of waste fractions should be per multi-residential building can be seen as low. This is because the problems mainly do not arise for the waste collection areas until after the capacity has been determined. It showed that the main factor behind the problem was the communication between the various actors in the process.

To compete or cooperate? three essays on the relationship between unions and employee and organizational outcomes: the moderating effect of management's response

Pohler, Dionne 11 1900 (has links)
In their highly influential work on the labour market impact of unions termed the collective voice/institutional response model (CVIR), Freeman & Medoff (1984) proposed that whether the unions monopoly or voice face would prevail greatly depended on the unions and managements willingness to compete or cooperate, respectively. However, these authors and the researchers that tested their ideas afterwards neither theorized about nor tested this key moderating condition of a unions impact. The result has been a confusing, mixed and generally inconclusive litany of research findings about the impact of unions at both the individual and organizational levels of analysis. I attempt to resolve this gap in CVIR by using the appropriateness framework (March 1994) to identify when and under what conditions management and unions, along with their members, will respond cooperatively or competitively toward each other. My empirical results are consistent with the idea that management response is a key moderating mechanism of a unions power and thus impact, contributing to zero or negative sum outcomes when management chooses to compete (i.e., union power is exerted in the direction of harmful monopoly effects) and positive sum outcomes when management chooses cooperation (i.e., union power is exerted in the direction of beneficial voice effects). In particular, when environmental cues lead the union and/or unionized employees to believe that management values voice, they will consider cooperation an appropriate response under the circumstances and reciprocate in-kind with other-regarding behaviors. On the other hand, when environmental cues lead the union or unionized employees to believe that management may potentially behave opportunistically, they will consider competition appropriate under the circumstances, and respond in-kind with self-serving, competitive behaviours. Drawing upon the resource-based view of the firm, I argue how a cooperative union-management relationship can be a source of sustainable competitive advantage for the organization (Barney, 1991). / Human Resources Management and Industrial Relations

Essays on choices, beliefs and adaptive behavior

Kühne, Regina 02 February 2015 (has links)
Diese Dissertation umfasst drei Aufsätzen, die sich mit Erwartungen, Entscheidungen und deren Rückwirkung auf die Umgebung beschäftigen. Der erste Aufsatz untersucht die Binnenwanderung von Ost- nach Westdeutschland. Dabei wird der Zusammenhang von Variation in ökonomischen Disparitäten zwischen der Ursprungs- und der Zielregion und Bildungsniveau, Alter und Arbeitsmarktstatus der wandernden Bevölkerung untersucht. Mit Hilfe der SOEP Daten von 1993 bis 2011 gelangt die Untersuchung zu dem Ergebnis, dass regionale Disparitäten in Verbindung mit der Selbstselektion der Wandernden stehen. Während die Wandernden im Durchschnitt jünger und besser ausgebildet als die Bleibenden sind, verringert sich dieser Unterschied, wenn die Differentiale in den Arbeitslosenquoten zwischen den Regionen steigen. Im zweiten Aufsatz entwickle ich ein Modell zur Untersuchung von prosozialem Verhalten in Begegnungen mit Fremden. Durch das Abstrahieren von Möglichkeiten der Reputationsbildung oder des Bestraftwerdens, entfallen die wesentlichen strategischen Motive für prosoziales Verhalten. Die Entscheidung prosozial zu Handeln ist dann nicht mehr strategisch vorteilhaft sondern intrinsisch motiviert durch Altruismus und einer Neigung sich an das Verhalten anderer anzupassen. In einem zweiten Schritt untersuche ich, ob die Erkenntnisse des Modells mit dem empirisch beobachteten Verhalten übereinstimmen. Der dritte Aufsatz skizziert eine (mögliche) Verhaltensstruktur und notwendige Bedingungen auf Mikroebene, die zu den beobachteten Verhaltensunterschieden in prosozialem Verhalten zwischen dem ländlichen und städtischen Raum führen. Den Rahmen des hier entwickelten Modells bildet das bekannte Gefangenen Dilemma, das wiederholt mit zufällig zugeordneten Partnern einer großen Gesellschaft gespielt wird. Das Modell bezieht Merkmale ein, die sich häufig in realen Begegnungen wiederfinden: imperfekte Information, freiwillige Teilnahme und eine Neigung sich dem Verhalten anderer anzupassen. / This thesis consists of three essays that analyze choices and beliefs to explore how both lead to adaptive behavior. The first essay examines the positive net migration flow from the eastern to western parts of Germany. The migration decision is substantially based on expectations about future developments. With economic conditions changing substantially over the past 20 years in the eastern part of Germany, the incentives to migrate have also altered, so changing the composition of the east-to-west migrant body. This essay explores variations in economic disparities between the region of origin and region of destination, relating them to changes in the skill level, age and labor force status of the migrant population. Analyzing SOEP data from 1993-2011, the findings suggest that, with falling wage differentials, older migrants are less frequent job-to-job movers and are more likely to be non-working prior to migration. Furthermore, while migrants tend to be younger and better educated than stayers, the group of movers becomes partly less distinct from the group of stayers with respect to the skill and age composition when regional disparities in employment opportunities increase. The second and the third essay of this thesis model the decision making process in social interactions between strangers. In these situations, choices are often affected by beliefs about others behavior. In the second essay of this work, I develop a simple model of prosocial behavior for encounters between strangers. By abstracting from the possibility of reputation building and punishment between anonymous partners, I remove the main strategic motives for prosocial behavior so reducing it to a simple non-strategic decision. The principal motivation to behave prosocially is then intrinsic, based on altruism, with a taste for conforming to the behavior of others. In this way, individual decisions are conditional on the behavior of others. Emerging equilibria will then explain the occurrence of prosocial or cooperative behavior within a given society. In a second step, I analyze whether the model’s predictions are consistent with the empirical evidence on the link between beliefs and prosocial behavior using data on blood donations. The third essay outline a (possible) micro-structure and conditions which lead to the observed urban-rural differences in cooperative behavior using agent-based modeling. The model presented here adapts the familiar framework of a prisoners dilemma which is played repeatedly with randomly matched members of a large population. I introduce features that are often found in real world interactions: imperfect information, voluntary participation and a taste for conforming to majority behavior. In this analysis, peoples beliefs about the level of cooperation in the population and their resulting behavior are determined endogenously. Both are governed principally by the experience that they derive from interactions. I present results of an agentbased simulation in order to study the emerging dynamic relationships, to examine how cooperative behavior evolves over time under different circumstances, and to determine how urban-rural differences in behavior emerge. The factors that give rise to rural-urban differences are heterogeneity in individual loss aversion or risk taking, and limited migration possibilities between rural and urban areas.
