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.

Government is analysed as the product of exchange among individuals who differ in their bargaining power. This approach shows why individuals agree to political institutions that give their governments extensive power, and why even the most powerful government benefits from constitutional rules constraining the government's power. This foundation is used to examine a wide range of government activities, including its protection of rights, its military activities, and democratic political institutions.

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."

This book brings together key players in the current debate on positive and normative science and philosophy and value judgements in economics. Both editors have engaged in these debates throughout their careers from its early foundations; Putnam as a doctorial student of Hans Reichenbach at UCLA and Walsh a junior member of Lord Robbins’s department at the London School of Economics, both in the early 1950s. This book collects recent contributions from Martha Nussbaum, Amartya Sen and Partha Dasgupta, as well as a new chapter from the editors.

This volume, explores the nature of economics as a science, including classic texts and newer essays.
