Book Description
As societies progress, old generations of social agents die and are replaced by new ones. This book explores what happens in this transition as the old guard instructs the new arrivals about the wisdom of their ways. Do new entrants listen and follow the advice of their elders or dismiss it? Is intergenerational advice welfare improving or can it be destructive? Does such advice enhance the stability of social conventions or disrupt it? Using the concept of an Intergenerational Game and the tools of game theory and experimental economics, this study delves into the process of social leaning created by intergenerational advice passed from generation to generation. This book presents a unique theoretical and empirical study of the dynamics of social conventions not offered elsewhere.

Book Description
In The Grammar of Society, first published in 2006, Cristina Bicchieri examines social norms, such as fairness, cooperation, and reciprocity, in an effort to understand their nature and dynamics, the expectations that they generate, and how they evolve and change. Drawing on several intellectual traditions and methods, including those of social psychology, experimental economics and evolutionary game theory, Bicchieri provides an integrated account of how social norms emerge, why and when we follow them, and the situations where we are most likely to focus on relevant norms. Examining the existence and survival of inefficient norms, she demonstrates how norms evolve in ways that depend upon the psychological dispositions of the individual and how such dispositions may impair social efficiency. By contrast, she also shows how certain psychological propensities may naturally lead individuals to evolve fairness norms that closely resemble those we follow in most modern societies.

Book Description
Are all film stars linked to Kevin Bacon? Why do the stock markets rise and fall sharply on the strength of a vague rumour? How does gossip spread so quickly? Are we all related through six degrees of separation? There is a growing awareness of the complex networks that pervade modern society. We see them in the rapid growth of the internet, the ease of global communication, the swift spread of news and information, and in the way epidemics and financial crises develop with startling speed and intensity. This introductory book on the new science of networks takes an interdisciplinary approach, using economics, sociology, computing, information science and applied mathematics to address fundamental questions about the links that connect us, and the ways that our decisions can have consequences for others.

Book Description
Inhaltsangabe:Abstract: Macroeconomics deals with the behaviour of the economy altogether and concentrates on fundamental and actual economic problems. Microeconomics deals with the behaviour of individuals and the aggregation of their actions in different institutional frameworks. Thus, both micro- and macroeconomics are doctrines to describe and understand individuals behaviour, activities and outcomes. So, why does one try to better understand? Individuals are curious , is a popular explanation. Another is that understanding may lead to a better outcome for individuals. There exist a lot of patterns of behaviour. One behaviour pattern is the so-called uniform behaviour. Imitation and mimicry belong to the basic instincts of every human being. Indeed, these patterns do not make immediate sense in terms of traditional macro- or microeconomic models. Still, they may be rational for an individual or a group of individuals. Learning by observing other individuals past actions and decisions may be of help to explain some otherwise puzzling phenomena about human behaviour. Apprehending individuals behaviour is not straightforward. It is not only profit or utility maximising that drives individuals minds. Sometimes, individuals just act because others act. An Informational Cascade is a situation in which every subsequent individual, based on the observation of others, makes the same choice or decision independent of his private information. Informational Cascades are present in our everyday life and in fields such as Economics, Politics, Scientific Theory, Finance or Zoology. The fact that this phenomenon does appear in innumerable situations is my motivation to closer examine Informational Cascades. Economics and above all economic behaviour is more than Statistics or Mathematics. It is Anthropology and Psychology as well. To combine and describe economics with the behaviour patterns of human beings, above all Informational Cascades and its environment , is the base of my licentiate. To link this phenomenon to economics and to bring it in an economic context, one has to grasp what exactly an Informational Cascade does describe. Why can one define an Informational Cascade as a gap between the practiced and the preached? Definitions and a simple example are given at the beginning of chapter two, followed by a characterisation of an Informational Cascade. The characterisation deals with the brittleness, idiosyncrasy and the error-sensitivity of [...]

Book Description
A great deal of economics is about law - the functioning of markets, property rights and their enforcement, financial obligations, and so forth - yet these legal aspects are almost never addressed in the academic study of economics. Conversely, the study and practice of law entails a significant understanding of economics, yet the drafting and administration of laws often ignore economic principle. The New Palgrave Dictionary of Economics and the Law is uniquely placed by the quality, breadth and depth of its coverage to address this need for building bridges. Drawn from the ranks of academics, professional lawyers, and economists in eight countries, the 340 contributors include world experts in their fields. Among them are Nobel laureates in economics and eminent legal scholars. First published in 1998 and now available in paperback for the first time, The New Palgrave Dictionary of Economics and the Law has established itself as a classic reference work in this important field.

Book Description
Analytical sociology is a strategy for understanding the social world. It is concerned with explaining important social facts such as network structures, patterns of residential segregation, typical beliefs, cultural tastes, and common ways of acting. It explains such facts by detailing in clear and precise ways the mechanisms through which the social facts were brought about. Making sense of the relationship between micro and macro thus is one of the central concerns of analytical sociology. The approach is a contemporary incarnation of Robert K. Merton's notion of middle-range theory and presents a vision of sociological theory as a tool-box of semi-general theories each of which is adequate for explaining certain types of phenomena. The Handbook brings together some of the most prominent sociologists in the world. Some of the chapters focus on action and interaction as the cogs and wheels of social processes, while others consider the dynamic social processes that these actions and interactions bring about.

Book Description
There remains an urgent need for a deeper discussion of the theoretical, political and federal dimensions of the European codification project. While much valuable work has already been undertaken, the chapters in this volume take as their starting point the proposition that further reflection and critical thought will enhance the quality and efficacy of the on-going work of the various codification bodies. The volume contains chapters by representatives of the Common Frame of Reference, the Study Group and the Acquis Group as well as by those who have not been involved in particular projects but who have previously commented more distantly on their work - for instance those belonging to the Trento Group, and the Social Justice Group. The chapters between them represent the most comprehensive attempt so far to survey the state of the codification project, its theoretical, political and federal foundations and the future prospects for enforcement and compliance.

Book Description
Professor Cheffins' lecture offers a path-breaking examination of potential trajectories for legal scholarship. Considerable attention is devoted to academic writing on law, but little has been said about the process by which the relevant literature evolves. This lecture focuses directly on the evolution of legal scholarship. It identifies five potential trajectories, revolving around concepts such as 'progress', 'paradigms', the marketplace for ideas, intellectual cycles, and fads and fashions. Professor Cheffins offers a summary of each trajectory and then tests the propositions he has advanced by means of a case study dealing with corporate law. He argues that scholarly trends in law develop in a manner that is at least partially consistent with each of the trajectories he identifies, but acknowledges that none captures fully the dynamics at work.
