Abstract

<p>This is a self-introduction of economics to legal policy making. Many economists study system building. They insist on market mechanism from the viewpoint of the fundamental theorem of welfare economics.</p><p>There are many cases of market failure, and they should be given much attention so that Pareto improvements can be made. In order to choose a Pareto efficient situation, we use the analysis of surplus. This requires the defective assumptions of measurability and a comparison of the utilities. We should use it by declaring to use them. It is important to make a system to assure some kind of equity and we lost some efficiency by it.</p><p>Economists use the assumption of individual rationality. In reality, individuals have many options and this complexity creates a computability problem. We must show the way of the irrationality of people before using paternalistic policies.</p>
