LawLaw is a set of rules that are created and are enforceable by social or governmental institutions to regulate behavior, with its precise definition a matter of longstanding debate. It has been variously described as a science and as the art of justice. State-enforced laws can be made by a group legislature or by a single legislator, resulting in statutes; by the executive through decrees and regulations; or established by judges through precedent, usually in common law jurisdictions.
Constitutional economicsConstitutional economics is a research program in economics and constitutionalism that has been described as explaining the choice "of alternative sets of legal-institutional-constitutional rules that constrain the choices and activities of economic and political agents". This extends beyond the definition of "the economic analysis of constitutional law" and is distinct from explaining the choices of economic and political agents within those rules, a subject of orthodox economics.
Mainstream economicsMainstream economics is the body of knowledge, theories, and models of economics, as taught by universities worldwide, that are generally accepted by economists as a basis for discussion. Also known as orthodox economics, it can be contrasted to heterodox economics, which encompasses various schools or approaches that are only accepted by a minority of economists. The economics profession has traditionally been associated with neoclassical economics. This association has however been challenged by prominent historians of economic thought like David Collander.
The Nature of the Firm"The Nature of the Firm" (1937) is an article by Ronald Coase. It offered an economic explanation of why individuals choose to form partnerships, companies, and other business entities rather than trading bilaterally through contracts on a market. The author was awarded the Nobel Memorial Prize in Economic Sciences in 1991 in part due to this paper. Despite the honor, the paper was written when Coase was an undergraduate and he described it later in life as "little more than an undergraduate essay.
Transaction costIn economics and related disciplines, a transaction cost is a cost in making any economic trade when participating in a market. The idea that transactions form the basis of economic thinking was introduced by the institutional economist John R. Commons in 1931, and Oliver E. Williamson's Transaction Cost Economics article, published in 2008, popularized the concept of transaction costs. Douglass C. North argues that institutions, understood as the set of rules in a society, are key in the determination of transaction costs.
Institutional economicsInstitutional economics focuses on understanding the role of the evolutionary process and the role of institutions in shaping economic behavior. Its original focus lay in Thorstein Veblen's instinct-oriented dichotomy between technology on the one side and the "ceremonial" sphere of society on the other. Its name and core elements trace back to a 1919 American Economic Review article by Walton H. Hamilton. Institutional economics emphasizes a broader study of institutions and views markets as a result of the complex interaction of these various institutions (e.
Law and economicsLaw and economics, or economic analysis of law, is the application of microeconomic theory to the analysis of law, which emerged primarily from scholars of the Chicago school of economics. Economic concepts are used to explain the effects of laws, to assess which legal rules are economically efficient, and to predict which legal rules will be promulgated.
ExternalityIn economics, an externality or external cost is an indirect cost or benefit to an uninvolved third party that arises as an effect of another party's (or parties') activity. Externalities can be considered as unpriced goods involved in either consumer or producer market transactions. Air pollution from motor vehicles is one example. The cost of air pollution to society is not paid by either the producers or users of motorized transport to the rest of society. Water pollution from mills and factories is another example.
