Reciprocity is the basis of social relations. It permits a peaceful and free society in which people and rights are respected. The essence of families and communities, it also enables the working of markets and organisations, while correcting their main failures. Reciprocity is also a basis of politics, and it justifies social policies. Although the importance of reciprocity has been widely recognised in other social sciences, it has, until recently, been somewhat ignored in economic analysis. Over the past three decades, economic theorist and moral philosopher Serge-Christophe Kolm has been at the forefront of research into the economics of the deepest aspects of societies. In Reciprocity, he provides a unique in-depth analysis of the motives, conducts, and effects of reciprocal relationships. In doing this, he explains crucial functionings of society and its economy, and the ways in which they can be improved. This book should be read by economists, sociologists, philosophers, and anyone concerned with understanding the economy of social relationships and its far-reaching consequences.

Trust is essential to economic and social transactions of all kinds, from choosing a marriage partner, to taking a job, and even buying a used car. The benefits to be gained from such transactions originate in the willingness of individuals to take risks by placing trust in others to behave in cooperative and non-exploitative ways. But how do humans decide whether or not to trust someone? Using findings from evolutionary psychology, game theory, and laboratory experiments, Trust and Reciprocity examines the importance of reciprocal relationships in explaining the origins of trust and trustworthy behavior. In Part I, contributor Russell Hardin argues that before one can understand trust one must account for the conditions that make someone trustworthy. Elinor Ostrom discusses evidence that individuals achieve outcomes better than those predicted by models of game theory based on purely selfish motivations. In Part II, the book takes on the biological foundations of trust. Frans de Waal illustrates the deep evolutionary roots of trust and reciprocity with examples from the animal world, such as the way chimpanzees exchange social services like grooming and sharing. Other contributors look at the links between evolution, cognition, and behavior. Kevin McCabe examines how the human mind processes the complex commitments that reciprocal relationships require, summarizing brain imaging experiments that suggest the frontal lobe region is activated when humans try to cooperate with their fellow humans. Acknowledging the importance of game theory as a theoretical model for examining strategic relationships, in Part III the contributors tackle the question of how simple game theoretic models must be extended to explain behavior in situations involving trust and reciprocity. Reviewing a range of experimental studies, Karen Cook and Robin Cooper conclude that trust is dependent on the complex relationships between incentives and individual characteristics, and must be examined in light of the social contexts which promote or erode trust. As an example, Catherine Eckel and Rick Wilson explore how people's cues, such as facial expressions and body language, affect whether others will trust them. The divergent views in this volume are unified by the basic conviction that humans gain through the development of trusting relationships. Trust and Reciprocity advances our understanding of what makes people willing or unwilling to take the risks involved in building such relationships and why.

This text, part of the McGraw-Hill Series in Social Psychology, is for the student with no prior background in social psychology. Written by Philip Zimbardo and Michael Leippe, outstanding researchers in the field, the text covers the relationships existing between social influence, attitude change and human behavior. Through the use of current, real-life situations, the authors illustrate the principles of behavior and attitude change at the same time that they foster critical thinking skills on the part of the reader.

Reciprocity Rules explores the rich and complicated relationships that develop between anthropologists and research participants over time. Focusing on compensation and the creation of friendship and “family” relationships, contributors discuss what, when, and how researchers and the people with whom they work give to each other in and beyond fieldwork. Through reflexivity and narrative, the contributors to this edited collection, who are in various stages in their professional careers and whose research spans three continents and eight countries, reflect on the ways in which they have compensated their research participants and given back to host communities, as well as the varied responses to their efforts. The contributors consider both material and non-material forms of reciprocity, stories of successes and failures, and the taken-for-granted notions of compensation, friendship, and “helping.” In so doing, they address the interpersonal dynamics of power and agency in the field, examine cultural misunderstandings, and highlight the challenges that anthropologists face as they strive to maintain good relations with their hosts even when separated by time and space. The contributors argue that while learning, following, openly discussing, and writing about the local rules of reciprocity are always challenging, they are essential to responsible research practice and ongoing efforts to decolonize anthropology.

Therapists Charlie and Linda Bloom have been married more than thirty-five years. Over a two-year period, they interviewed twenty-seven couples who had been together for an average of thirty years and seemed as happy as newlyweds. Were they just lucky? The Blooms found that these couples had faced real challenges - difficulties with children and stepchildren, war wounds, infidelity, and financial ruin. They also found that with loving dialogue and open hearts, the couples had found ways to heal, grow, and deepen their commitment through, and not despite, their challenges. The Blooms distill this real-world wisdom into practical, positive actions any couple can take to achieve or regain not just a good marriage but a great one.

This dissertation was designed to examine whether people feel more gratitude in response to benefits rendered by strangers and acquaintances than in response to benefits provided by established reciprocal relationship partners and genetic relatives, and whether the gratitude experienced in response to benefits provided by those novel non-kin benefactors is more likely to lead to motivation to reciprocate than is the gratitude elicited by benefits rendered by genetic relatives and established reciprocal altruism partners. It was hypothesized that gratitude would be more salient when benefits are rendered by strangers and acquaintances than by well-known individuals in already-established reciprocal relationships or in kin relationships. Using self-report questionnaires from 128 University of Miami students, this study revealed that benefit recipients reported stronger urges to reciprocate, engaged in more reciprocal prosocial behavior, and were more likely to respond to the feeling of gratitude with prosocial reciprocation when benefitted by friends and siblings than when benefited by acquaintances. Additionally, post-benefit contact significantly predicted reciprocal action, and post-benefit contact mediated the effects of relationship type on recipients' reciprocal actions and urges to reciprocate. Although findings did not support the original hypotheses, these findings indicate that there are other factors correlated with relationship type that influence an individual's likelihood of feeling grateful and reciprocating. To the extent that these factors (e.g., a high likelihood of future post-benefit interaction) are present, they might prevent mechanisms designed for reciprocal altruism from creating internal motivations to engage in reciprocal prosocial behavior.
