Introduction: Law and Economics in a Nutshell

This chapter provides a concise exploration of the principles and methodology underpinning the interdisciplinary field of law and economics. The chapter delves into the fundamental tenets of law and economics, emphasizing its roots in neoclassical economics, and examines how economic analysis may assist in increasing the efficiency of law and legal norms in terms of the desired economic outcomes. That includes brief explanations of efficiency, utility, and rational choice theory, which serve as the bedrock for analyzing legal systems and policies. Moreover, this chapter explains standard law and economics methodological tools used to evaluate legal rules and institutions, such as cost-benefit analysis, incentive alignment, and economic modelling in assessing the impacts of legal regulation. Through provided theoretical explanations, readers may gain insights into how law and economics inform and affect legal decision-making, offering a valuable lens through which to view (patent-related) legal issues and policies.
