Previous issue date: 2017-02-21 / Fundação de Amparo à Pesquisa do Estado de São Paulo (FAPESP) / Corruption is an object of study in several researches, but only recently it began to be investigated experimentally. Despite the progress, some gaps remain open, particularly in regards to the variables of which the observed behaviors are function, one aspect in which behavior analysis can contribute to operationalize the phenomenon and investigate the environmental variables that control these behaviors characterized as corrupt. One way to study this phenomenon is to expose the participants to a context in which they need to contribute to producing a particular public good, and then need to make decisions about how this good will be distributed among all participants. In this context, the participant can make three decisions: distribute in an egalitarian way; Distribute in an unequal way, favoring others, or distribute in an unequal way, favoring their own gains. A participant who makes distributions unequally for his own benefit shall behaving in a manner analogous to that described in the crime of embezzlement. Through the Public Goods Game (JBP), by modifying its original protocol, allowing the participants to manage the public resource, deciding how it will be distributed, it is possible to experimentally study this type of corrupt behavior. The aim was to investigate how the participants managed public resources under a PGG. Six participants were exposed to the procedure. They had to decide how the resource produced by her/his own contribution and that of the other players would be distributed among them. Five participants made unequal distributions, i.e, allocated most of the resources to themselves. This type of distribution is in correspondence with an embezzlement definition, allowing an approximation to real contexts. From these results, we suggest changes in the contingencies that control the occurrence of this type of behavior. / A corrupção foi objeto de estudo em diversas pesquisas, mas apenas recentemente ela passou a ser investigada experimentalmente. Apesar dos avanços obtidos, algumas lacunas permanecem em aberto, principalmente no que diz respeito as variáveis das quais os comportamentos observados são função, aspecto em que a Análise do Comportamento pode contribuir ao operacionalizar o fenômeno e investigar as variáveis ambientais que controlam estes comportamentos caracterizados como corruptos. Uma maneira de estudar este fenômeno é expor os participantes a um contexto em que eles precisem contribuir para produzir um determinado bem público, e em seguida, precisem tomar decisões a respeito da maneira como este bem será distribuído entre todos. Neste contexto, o participante pode tomar três decisões: distribuir de maneira igualitária; distribuir de maneira desigual, favorecendo os demais, ou distribuir de maneira desigual, favorecendo os seus próprios ganhos. Um participante que faça distribuições desigualmente em benefício próprio estará de comportando de maneira análoga a descrita no crime de peculato. Utilizando o Jogo dos Bens Públicos (JBP), modificando o seu protocolo original, é possível permitir que os participantes façam a gestão do recurso público, decidindo como ele será distribuído entre si mesmo e os demais participantes, o que torna possível estudar experimentalmente este tipo de comportamento corrupto. O objetivo deste estudo foi investigar o comportamento de contribuir e distribuir recursos públicos sob controle da quantidade de recursos produzidos pela contribuição de todos os participantes. Ao todo, seis participantes foram recrutados. As contingências programadas no presente estudo foram o número de fichas que um participante possuía em sua “carteira” no início da tentativa (condição antecedente), a resposta de contribuir e distribuir as fichas e o ganho obtido pela contribuição e distribuição efetuada. Como resultado, todos os participantes emitiram respostas de contribuições desiguais, isto é, contribuíram menos do que os demais participantes, e cinco destes participantes emitiram respostas de distribuições desiguais, isto é, distribuíram para si mesmos a maior parte das fichas produzidas. Esse tipo de distribuição encontra correspondência na definição de peculato, o que permite aproximar este estudo de contextos reais. A partir dos resultados discute-se mudanças nas contingências em vigor para controlar a ocorrência deste tipo de comportamento.

Previous issue date: 2012-05-28 / Coordena??o de Aperfei?oamento de Pessoal de N?vel Superior / Human cooperation is a hallmark of this species due to its wide extension to genetically unrelated
individuals and complex division of labor. It is considered an evolutionary puzzle, because the
theory of evolution by natural selection predicts that self-interested individuals tend to be selected.
Different theories have been proposed to explain the evolution of cooperation, which the most
important are kin selection and reciprocal altruism. Considering the evolutionary continuity
between species, humans and other primates have several common traits that help to promote
cooperation between individuals of these species. Two features, however, seem to be particularly
humans: inequality aversion and preferences in relation to others. Although human cooperation is
not necessarily related to morality, cooperative traits are the basis for moral tendencies. The
development of human morality is a combination of early prosocial tendencies, cooperative skills
displayed at different ages, social learning and cultural transmission of norms. The social stimulus
seems to be particularly important in promoting cooperative behavior in children and adults. In
order to study the influence of social stimuli, as verbal feedback, on children cooperation, a study
was conducted with children in a public goods game. 407 children from public schools in Natal /
RN, divided into 21 groups, between six and nine years, participated in eight rounds of this game.
After each round, seven groups received praise for larger donations, seven groups have been
criticized by smaller donations, and the other seven received no comment. Children cooperated
more when criticized, without significant differences between sexes, although young children have
cooperated more negative than older children. The results are likely related to the anticipation and
avoidance of punishment associated with the feedback (although this did not occur), and greater
sensitivity to the authority in younger children. Nevertheless, the cooperation decreased in all
groups until the last day of play. The results suggest an early sensitivity to moral punishment,
whose role in the maintenance of social relations must have been important in the evolution of
cooperation in humans / A coopera??o humana ? um tra?o distintivo da esp?cie, devido ? sua ampla extens?o ? n?o
aparentados e elaborada divis?o do trabalho. ? considerada um quebra-cabe?a evolucionista, tendo
em vista que a teoria da evolu??o por sele??o natural prev? que indiv?duos auto-interessados tendem
a ser selecionados. Diferentes teorias foram propostas para explicar a evolu??o da coopera??o,
sendo as mais importantes a sele??o de parentesco e o altru?smo rec?proco. Considerando a
continuidade evolutiva entre esp?cies, seres humanos e outros primatas possuem v?rios tra?os em
comum que ajudam a promover a coopera??o entre indiv?duos dessas esp?cies. Duas caracter?sticas,
no entanto, parecem ser particularmente humanos: a avers?o ? desigualdade e as prefer?ncias em
rela??o aos outros. Embora a coopera??o humana n?o necessariamente esteja relacionada ?
moralidade, tra?os cooperativos servem de base para tend?ncias morais. O desenvolvimento da
moralidade humana resulta da combina??o de tend?ncias pr?-sociais precoces, de habilidades
cooperativas exibidas em diferentes idades, de aprendizagem social e transmiss?o cultural de
normas. O est?mulo social parece ser particularmente importante na promo??o de comportamentos
cooperativos em crian?as e adultos. Tendo como objetivo estudar a influ?ncia do est?mulo social,
sob a foma de feedback verbal sobre a coopera??o infantil, foi realizado um estudo com crian?as em
um jogo de bens p?blicos. 407 crian?as de escolas p?blicas de Natal/RN, divididas em 21 grupos,
entre seis e nove anos, participaram de oito partidas desse jogo. Ao fim de cada partida, sete grupos
receberam elogios pelas doa??es maiores, sete grupos foram criticados pelas doa??es menores, e os
outros sete n?o receberam nenhum coment?rio. Crian?as cooperaram mais em situa??es de cr?tica,
sem diferen?as significativas entre sexo, embora crian?as mais jovens tenham cooperado mais em
feedback negativo do que as crian?as mais velhas. Os resultados provavelmente est?o relacionados ?
expectativa e ? esquiva de puni??o associada ao feedback (embora esta n?o ocorresse), e ? maior
sensibilidade ? autoridade em crian?as mais jovens. Apesar disso, a coopera??o diminuiu em todos
os grupos at? o ?ltimo dia de jogo. Os resultados apontam para uma sensibilidade precoce ? puni??o
moral, cujo papel na manuten??o das rela??es sociais deve ter sido importante na evolu??o da

Contribuer volontairement au bien public en groupe élargi : évolution via le triptyque observation, explication, représentation sur fond d'un classique / Voluntarily contributing to public good in larger group : evolution through triptych observation, explanation, modeling against a backdrop of a classicChambre, Damien 23 March 2016 (has links)
Nous capturons la décision de contribuer volontairement au bien public en groupe restreint et important, en nous basant sur un classique de l’économie expérimentale. Contrairement aux prévisions, la décision dépend négativement du rendement du bien public en groupe important. Les joueurs percevraient l’enjeu comme faible. La décision dépend positivement, mais trop fragilement, du nombre de bénéficiaires du bien public en groupe restreint et n’en dépend pas en groupe important. La décision dépend toujours négativement de l’avancement du jeu, mais sans convergence vers la stratégie dominante. Le mode de calcul de la rémunération aurait une incidence. La réciprocité et l’aversion à l’iniquité sont toujours absentes. Cela serait lié au fait que les joueurs ne sont pas représentatifs de la population. Dans le sens des prévisions, deux propriétés de l’investissement public se dégagent et concordent avec les décisions observées dans la vie courante. La décision dépend positivement du rendement public en groupe restreint, dans la logique de cet incitatif à contribuer. L’altruisme est présent sous forme de traces en groupe restreint et disparaît en groupe important, désavantagé par la dilution du don. L’éclat chaleureux du don voit sa présence s’accroître en groupe important, favorisé par le changement de nature du don. Nous modélisons ces résultats en nous basant sur l’équilibre Logit. Il s’agit de fonctions de réponse perturbées comprenant différents composants. Les propriétés de ces fonctions rencontrent adéquatement la prise de décision et ont l’avantage de ne pas représenter certains errements empiriques. / We capture decision-making to voluntarily contribute to public good in small and large group, based on a Classic in experimental economics. Contrary to forecasts, decision-making is negatively correlated with Marginal Per Capita Return to investing in the public group in large group. Subjects appear to view the issue as weak. Decision-making is positively correlated, but too weakly, with number of subjects in small group and is not correlated in large group. Decision-making is always negatively correlated with game process, but without convergence to the dominant strategy. The method used in calculating compensation can have an impact. Reciprocity and aversion to inequity are always missing. This can be linked to the fact that subjects are not representative of the true population. In line with forecasts, two properties of public investment emerge and are consistent with decision-making of everyday life. Decision-making is negatively correlated with Marginal per Capita Return in small group, following logic of this incentive to contribute. There are signs of altruism in small group disappearing in larger group, disadvantaged by dilution of Giving. Presence of Warm-Glow Giving increases in large group, supported by changing nature of Giving. We model these results using the Logit equilibrium. It is noisy response functions including different components. Function’s properties properly meet decision-making and have advantage of not modeling some empirical contradictions.

Participatory interventions for pro-social and collective action in natural resource management: An institutional and behavioural approach / Intervenciones participativas para la acción pro-social y colectiva en la gestión de los recursos naturales. Una aproximación desde el análisis institucional y del comportamientoOrtiz-Riomalo, Juan Felipe 16 December 2020 (has links)
One of the main environmental policy challenges is convincing individuals and organisations to engage in socially desirable courses of action; that is, to have them internalise the consequences of their decisions. As contributions from institutional and behavioural economics have indicated, policies aimed at fostering pro-social action can be ineffective and even counterproductive if the interests and concerns of the relevant actors are not properly considered throughout the policy process. In fact, international conventions and national legislation around the world generally recommend stakeholder involvement in order to properly address pressing environmental challenges. The evidence that underpins and informs this recommendation, however, is still insufficient and scattered across different strands of literature. On the one hand, research on participatory governance has indeed systematically documented the potential for policymakers and resource managers to obtain high-quality, context-specific and legitimate input for environmental policymaking from participatory processes. On the other, the available research has also cast doubt on the potential of participatory processes to produce concrete change in (pro-social) action on the ground. In general, the success of these processes ultimately depends on their design, implementation and context. However, most of these conclusions stem from rich qualitative accounts of participatory processes, structured comparisons of cases and systematic reviews of case studies and the available literature. With this type of evidence, it is difficult to neatly identify the impact of participatory interventions on pro-social and cooperative behaviour and systematically assess the underlying mechanisms. This thesis addresses these knowledge gaps. The thesis investigates the extent to which and the mechanisms by which participatory interventions could foster (or hinder) pro-social and collective action for natural resource management and environmental protection. It comprises four chapters, each constituting a stand-alone, self-contained academic paper. Throughout the different chapters, the thesis reviews and integrates insights from the literature on participatory governance and from the institutional and behavioural analyses of pro-social and collective action. Furthermore, using two laboratory economic experiments (Chapters 3 and 4) and one framed lab-in-the-field experiment (Chapter 5), the thesis systematically assesses specific hypotheses concerning the potential impacts of participatory interventions on cooperative and pro-social behaviour and the underlying mechanisms of these impacts. The introductory chapter of the dissertation gathers, presents and discusses the insights gathered from each chapter. It expands on the motivations for the thesis, presents the general and specific research gaps and questions the thesis tackles and clarifies the conceptual, theoretical and methodological foundations upon which the thesis is grounded. Chapter 2 (entitled Participatory interventions for collective action in environmental and natural resource management) reviews the literature on participatory governance together with the literature on collective action in natural resource and environmental management. The main goal of this review is to contribute to integrating the main insights from both strands of literature regarding (a) the potential of participatory interventions to foster collective action and (b) the channels through which they might foment (or hinder) collective action. It therefore seeks to help integrate the insights from these different strands of literature, which, although related, have generally been disconnected until now. The chapter draws on the Institutional Analysis and Development (IAD) framework to organise these insights within a coherent conceptual framework. As the results of this literature review indicate, participatory interventions have the potential to foster collective action through two channels. Firstly, by helping resource users to change (and enhance) the rules, norms and strategies that constrain and guide their behaviour (the indirect channel) and, secondly, by directly influencing the specific behavioural factors (e.g. knowledge, trust, preferences, perceptions and beliefs) that collective action hinges upon (the direct channel). However, to sustain collective action, the relevant literature has consistently emphasised that trust needs to be continually cultivated and ensured. Therefore, in line with insights from earlier studies on participatory governance, the results of this literature review also indicate that practitioners and policymakers must not only design participatory interventions carefully to effectively build the trust needed to heighten and sustain collective action, but participatory interventions must also be adequately embedded within the broader (social-ecological and governance) context, providing for follow-up, enforcement, monitoring and conflict-resolution mechanisms. From Chapter 3 through Chapter 5, the thesis focuses on the direct channel, studying the potential of participatory interventions to directly influence behaviour within relevant economic action situations such as social dilemma and distributive action situations. Within a given environment and institutional context, the studies recreate processes commonly facilitated within participatory interventions. Chapter 3 assesses the effects of externally structured and facilitated processes of information exchange, and Chapters 4 and 5 examine the impact of inducing perspective-taking via role-switching techniques (Chapter 4) and instructions (Chapter 5). Thanks to this experimental approach, it is possible to systematically assess the behavioural impacts of these types of processes as well as the underlying mechanisms. Chapter 3 (entitled Structuring communication effectively for environmental cooperation) starts by reviewing previous experimental studies on the effects of two-way communication in social dilemmas to identify the elements that are commonly involved in effective communication processes. This review notes four cooperation-enhancing components of communication: (i) problem awareness, (ii) exploration of strategies to tackle the problem at hand, (iii) agreement on desirable joint strategies and (iv) ratification of agreed-upon strategies. A total of 560 students at Osnabrück University participated in a laboratory implementation of a voluntary contribution mechanism; a public goods game. The experiment implemented a series of interventions that represented these components of communication and contrasted the resulting levels of cooperation with the average outcomes of control groups interacting under either free (unstructured) communication or no communication whatsoever. The intervention that facilitated agreement on a common strategy (i.e. the combination of (ii) and (iii)) was particularly effective at boosting cooperation. Furthermore, combined with interventions promoting problem awareness and ratification, this intervention produced levels of cooperation similar to the average levels of cooperation observed in groups with free-form communication. The results of this experiment expand the understanding in the literature of the role of communication in social dilemmas and provide insights into the potential of structured and facilitated processes of information exchange and social interaction to foster collective action for environmental management. Chapter 4 (The effects of inducing perspective-taking through role reversal in a give-and-take a dictator game on pro-social behaviour) and Chapter 5 (Perspective-taking for pro-social behaviour in watershed management) deal with the effects of inducing perspective-taking on unilateral pro-social behaviour. The results outlined in Chapter 4 indicate that perspective-taking, induced through role reversal, can be associated with significant average changes in the participants’ self-reported state of emotions (in terms of both empathic and positive as well as in distressing and negative emotions). The emotional reactions that the role reversal seems to influence, however, do not appear to result in significantly more (or less) pro-social behaviour. The chapter explores and discusses two plausible explanations for these results, namely the transient effects of emotional reactions and the opposing effects of diverging emotional reactions on pro-social behaviour. These results come from the analysis of data from 144 students at Osnabrück University who participated as dictators in a laboratory implementation of a give-and-take dictator game. The design of the experiment allows the identification of the effect of inducing decision-makers to experience the other person’s position through unilateral role reversal on pro-social behaviour. During the simulation round, dictators in treatment groups experienced how it would feel to be in the role of the recipient. Dictators in the control groups only learned about the distributional consequences of their allocation decisions on recipients. Hence, through a treatment comparison, it was possible to single out the effects resulting from temporarily taking on the position of the other participant. To understand the underlying drivers of a potential behavioural change, the study elicited participants’ emotional states both before and after the simulation round. The results in Chapter 5 indicate that inducing perspective-taking can be associated with relatively greater pro-social behaviour based on an experimental study of downstream farmers’ behaviour in a watershed management context. Moreover, the provision of information on the social-ecological context during the perspective-taking exercise cannot account for the different behavioural patterns in the treatment and control groups. These results come from a lab-in-the-field experiment carried out with 177 downstream farmers in a Peruvian watershed. In the experiment, farmers in the treatment groups were motivated to imagine the upstream farmers’ perspective (i.e. to think about their thoughts and feelings) before deciding on whether or not to contribute to an initiative in the upper watershed. The initiative intends to help upstream farmers improve their well-being without compromising the water supply downstream. The behaviour of farmers in the treatment groups was compared against the behaviour of farmers in the control groups wherein perspective-taking was not induced. Taken together, the results of Chapter 4 and Chapter 5 illustrate the potential of inducing perspective-taking—commonly promoted in participatory processes—to trigger pro-social behaviour in economic situations. It can indeed alter relevant behavioural variables and trigger pro-social behaviour in distributive and social-dilemma situations. Nevertheless, as the literature on perspective-taking has previously indicated, the final effects depend on the specific procedures by which and the situations and contexts wherein perspective-taking is induced. Based on these findings, it is possible to sustain that participatory interventions do have the potential to effect changes in pro-social and cooperative behaviour at both the collective and individual level. Whether this impact is realised or hindered hinges on the procedures and contexts of participatory interventions. It would also depend on the mechanisms provided to follow up on the initiated processes and sustain and build upon the early outcomes. The contributions of this thesis are threefold. Firstly, it integrates insights from the literature on the institutional and behavioural analysis of pro-social and collective action and the literature on participatory governance for natural resource management. Secondly, it generates new evidence, based on experimental methods, in terms of the potential for participatory interventions to foster pro-social and collective action, and in terms of the mechanisms by which participatory methods and processes could effectively impact (or hinder) pro-social and cooperative behaviour. In this way, the thesis helps to bridge the gap of knowledge in terms of how participatory interventions can effectively change behaviour and, subsequently, encourage socially desirable social-ecological outcomes. In doing so, it also adds to the understanding of pro-social and cooperative human behaviour and the way that the processes of information-exchange and perspective-taking, which are often facilitated by participatory processes, may (or may not) advance it. Research on participation is, however, still ongoing and, in terms of the way forward, the thesis makes a third, methodological contribution. It demonstrates how experimental research in both the laboratory and in the field, conducted under a coherent conceptual and methodological framework, can complement one another and shed light on the extent to which and the means by which participatory interventions can produce changes in behaviour. The experimental method, in terms of both laboratory and field experiments, can therefore complement the set of methods traditionally employed to analyse participatory processes. The results of the studies comprising the thesis underscore the importance of carefully analysing the policy process. As contributions from the behavioural literature have repeatedly indicated, human behaviour is driven by a combination of self-regarding, social and procedural preferences. Hence, addressing pressing environmental challenges involving externalities and social dilemmas not only entails getting the policy design right to synergistically coordinate and orchestrate these different types of preferences. It also requires careful design, analysis and implementation of the activities and methods that structure and facilitate stakeholder interactions throughout the policy process.
