The Foundations of Positive and Normative Economics: A Handbook is the first book in a new series by Andrew Caplin and Andrew Schotter. There is currently no guide available on the rapidly changing methodological frontiers of the field of economics. Economists have been introducing new theories and new sources of data at a remarkable rate in recent years, and there are widely divergent views both on how productive these expansions have been in the past, and how best to make progress in the future. The speed of these changes has left economists ill at ease, and has created a backlash against new methods. The series will debate these critical issues, allowing proponents of a particular research method to present proposals in a safe yet critical context, with alternatives being clarified. This first volume, written by some of the most prominent researchers in the discipline, reflects the challenges that are opened by new research opportunities. The goal of the current volume and the series it presages, is to formally open a dialog on methodology. The editors' conviction is that such a debate will rebound to the benefit of social science in general, and economics in particular. The issues under discussion strike to the very heart of the social scientific enterprise. This work is of tremendous importance to all who are interested in the contributions that academic research can make not only to our scientific understanding, but also to matters of policy.

What effects do laws have? Do individuals drive more cautiously, clear ice from sidewalks more diligently, and commit fewer crimes because of the threat of legal sanctions? Do corporations pollute less, market safer products, and obey contracts to avoid suit? And given the effects of laws, which are socially best? Such questions about the influence and desirability of laws have been investigated by legal scholars and economists in a new, rigorous, and systematic manner since the 1970s. Their approach, which is called economic, is widely considered to be intellectually compelling and to have revolutionized thinking about the law. In this book Steven Shavell provides an in-depth analysis and synthesis of the economic approach to the building blocks of our legal system, namely, property law, tort law, contract law, and criminal law. He also examines the litigation process as well as welfare economics and morality. Aimed at a broad audience, this book requires neither a legal background nor technical economics or mathematics to understand it. Because of its breadth, analytical clarity, and general accessibility, it is likely to serve as a definitive work in the economic analysis of law.

This paper is concerned primarily with certain methodological problems that arise in constructing the "distinct positive science" that John Neville Keynes called for, in particular, the problem how to decide whether a suggested hypothesis or theory should be tentatively accepted as part of the "body of systematized knowledge concerning what is."

For over a century the economics profession has extended its reach to encompass policy formation and institutional design while largely ignoring the ethical challenges that attend the profession's influence over the lives of others. Economists have proven to be disinterested in ethics. Embracing emotivism, they often treat ethics a matter of mere preference. Moreover, economists tend to be hostile to professional economic ethics, which they incorrectly equate with a code of conduct that would be at best ineffectual and at worst disruptive to good economic practice. But good ethical reasoning is not reducible to mere tastes, and professional ethics is not reducible to a code. Instead, professional economic ethics refers to a new field of investigation-a tradition of sustained and lively inquiry into the irrepressible ethical entailments of academic and applied economic practice. The Oxford Handbook of Professional Economic Ethics explores a wide range of questions related to the nature of ethical economic practice and the content of professional economic ethics. It explores current thinking that has emerged in these areas while widening substantially the terrain of economic ethics. There has never been a volume that poses so directly and intensively the question of the need for and content of professional ethics for economics. The Handbook incorporates the work of leading scholars and practitioners, including academic economists from various theoretical traditions; applied economists, beyond academia, whose work has direct and immense social impact; and philosophers, professional ethicists, and others whose work has addressed the nature of "professionalism" and its implications for ethical practice.
