The course provides the analytical foundations for legal practice in the modern world — a world in which sound legal advice requires the mastery of the techniques and language of disciplines such as economics, decision theory and game theory. After a brief review of the methodology of law and economics, this course exposes students to a broad survey of micro-economics, decision-theory and game-theory concepts. These analytical methods play a crucial role in the design and understanding of legal rules. The second part of the course builds on these premises to study the economic structure of several areas of law. Through this course students will develop a framework for the analysis of legal rules that will aid them in the remainder of their legal studies and professional life.
