The tendency to reciprocate – to return good for good and evil for evil – is a potent force in human life, and the concept of reciprocity is closely connected to fundamental notions of ‘justice’, ‘obligation’ or ‘duty’, ‘gratitude’ and ‘equality’. In Reciprocity, first published in 1986, Lawrence Becker presents a sustained argument about reciprocity, beginning with the strategy for developing a moral theory of the virtues. He considers the concept of reciprocity in detail, contending that it is a basic virtue that provides the basis for parental authority, obligations to future generations, and obedience to law. Throughout the first two parts of the book, Becker intersperses short pieces of his own narrative fiction to enrich reflection on the philosophical arguments. The final part is devoted to extensive bibliographical essays, ranging over anthropology, psychology, political theory and law, as well as the relevant ethics and political philosophy.
This book covers the development of reciprocity laws, starting from conjectures of Euler and discussing the contributions of Legendre, Gauss, Dirichlet, Jacobi, and Eisenstein. Readers knowledgeable in basic algebraic number theory and Galois theory will find detailed discussions of the reciprocity laws for quadratic, cubic, quartic, sextic and octic residues, rational reciprocity laws, and Eisensteins reciprocity law. An extensive bibliography will be of interest to readers interested in the history of reciprocity laws or in the current research in this area.
Combinatorial reciprocity is a very interesting phenomenon, which can be described as follows: A polynomial, whose values at positive integers count combinatorial objects of some sort, may give the number of combinatorial objects of a different sort when evaluated at negative integers (and suitably normalized). Such combinatorial reciprocity theorems occur in connections with graphs, partially ordered sets, polyhedra, and more. Using the combinatorial reciprocity theorems as a leitmotif, this book unfolds central ideas and techniques in enumerative and geometric combinatorics. Written in a friendly writing style, this is an accessible graduate textbook with almost 300 exercises, numerous illustrations, and pointers to the research literature. Topics include concise introductions to partially ordered sets, polyhedral geometry, and rational generating functions, followed by highly original chapters on subdivisions, geometric realizations of partially ordered sets, and hyperplane arrangements.
A powerful new kind of competitive advantage is now possible thanks to technological and social disruptions that are already occurring. These disruptions revolutionize how companies can partner to create new growth. The Reciprocity Advantage shares a model for creating that growth: define your right-of-way (the underutilized resources you already own that you can share with others), partner to do what you can’t do alone, experiment to learn, and scale the new business at low risk. Reciprocity and advantage are words that are not normally seen together, but reciprocity—giving now to get later—will become a normal part of winning in the future. The Reciprocity Advantage shows you how to leverage new forces like digital natives and cloud-served supercomputing now into massively scalable, profitable, incremental growth for your business. Provocative and pragmatic, leading ten-year forecaster Bob Johansen and experienced business developer Karl Ronn describe how to lean in to disruptions to create new growth for your business. They include actual cases showing early successes for a range of companies and nonprofits like IBM, Microsoft, Google, Apple, and TED. They then provide key exercises to define your promising new ideas and nurture them into healthy new businesses. Their recommendations are based on practical experience in managing the problems of new business creation and many years of helping others see the future more clearly. Distilled from hands-on work, this book gets you started today on creating your own reciprocity advantage.
A fascinating look at the evolutionary origins of cooperation Why do humans, uniquely among animals, cooperate in large numbers to advance projects for the common good? Contrary to the conventional wisdom in biology and economics, this generous and civic-minded behavior is widespread and cannot be explained simply by far-sighted self-interest or a desire to help close genealogical kin. In A Cooperative Species, Samuel Bowles and Herbert Gintis—pioneers in the new experimental and evolutionary science of human behavior—show that the central issue is not why selfish people act generously, but instead how genetic and cultural evolution has produced a species in which substantial numbers make sacrifices to uphold ethical norms and to help even total strangers. The authors describe how, for thousands of generations, cooperation with fellow group members has been essential to survival. Groups that created institutions to protect the civic-minded from exploitation by the selfish flourished and prevailed in conflicts with less cooperative groups. Key to this process was the evolution of social emotions such as shame and guilt, and our capacity to internalize social norms so that acting ethically became a personal goal rather than simply a prudent way to avoid punishment. Using experimental, archaeological, genetic, and ethnographic data to calibrate models of the coevolution of genes and culture as well as prehistoric warfare and other forms of group competition, A Cooperative Species provides a compelling and novel account of how humans came to be moral and cooperative.
John V. Murra's Lewis Henry Morgan Lectures, originally given in 1969, are the only major study of the Andean "avenue towards civilization." Collected and published for the first time here, they offer a powerful and insistent perspective on the Andean region as one of the few places in which a so-called "pristine civilization" developed. Murra sheds light not only on the way civilization was achieved here--which followed a fundamentally different process than that of Mesopotamia and Mesoamerica--he uses that study to shed new light on the general problems of achieving civilization in any world region. Murra intermixes a study of Andean ecology with an exploration of the ideal of economic self-sufficiency, stressing two foundational socioeconomic forces: reciprocity and redistribution. He shows how both enabled Andean communities to realize direct control of a maximum number of vertically ordered ecological floors and the resources they offered. He famously called this arrangement a "vertical archipelago," a revolutionary model that is still examined and debated almost fifty years after it was first presented in these lecture. Written in a crisp and elegant style and inspired by decades of ethnographic fieldwork, this set of lectures is nothing less than a lost classic, and it will be sure to inspire new generations of anthropologists and historians working in South America and beyond.
The Handbook on the Economics of Giving, Reciprocity and Altruism provides a comprehensive set of reviews of literature on the economics of nonmarket voluntary transfers. The foundations of the field are reviewed first, with a sequence of chapters that present the hard core of the theoretical and empirical analyses of giving, reciprocity and altruism in economics, examining their relations with the viewpoints of moral philosophy, psychology, sociobiology, sociology and economic anthropology. Secondly, a comprehensive set of applications are considered of all the aspects of society where nonmarket voluntary transfers are significant: family and intergenerational transfers; charity and charitable institutions; the nonprofit economy; interpersonal relations in the workplace; the Welfare State; and international aid.*Every volume contains contributions from leading researchers*Each Handbook presents an accurate, self-contained survey of a particular topic *The series provides comprehensive and accessible surveys
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.

The choice of topics in this book may seem somewhat arbitrary, even though we have attempted to organize them in a logical structure. The contents reflect the path of 'search and discovery' followed by us, on and off, for the in fact last twenty years. In the winter of 1970-71 one of the authors (C. A. ), on sah baticalleave with L. R. O. Storey's research team at the Groupe de Recherches Ionospheriques at Saint-Maur in France, had been finding almost exact symme tries in the computed reflection and transmission matrices for plane-stratified magnetoplasmas when symmetrically related directions of incidence were com pared. At the suggestion of the other author (K. S. , also on leave at the same institute), the complex conjugate wave fields, used to construct the eigenmode amplitudes via the mean Poynting flux densities, were replaced by the adjoint wave fields that would propagate in a medium with transposed constitutve tensors, et voila, a scattering theorem-'reciprocity in k-space'-was found in the computer output. To prove the result analytically one had to investigate the properties of the adjoint Maxwell system, and the two independent proofs that followed, in 1975 and 1979, proceeded respectively via the matrizant method and the thin-layer scattering-matrix method for solving the scattering problem, according to the personal preferences of each of the authors. The proof given in Chap. 2 of this book, based on the hindsight provided by our later results, is simpler and much more concise.
