Law and economics in the context of "Aaron Director"

Jurisprudence, also known as theory of law or philosophy of law, is the examination in a general perspective of what law is and what it ought to be. It investigates issues such as the definition of law; legal validity; legal norms and values; and the relationship between law and other fields of study, including economics, ethics, history, sociology, and political philosophy.

Modern jurisprudence began in the 18th century and was based on the first principles of natural law, civil law, and the law of nations. Contemporary philosophy of law addresses problems internal to law and legal systems and problems of law as a social institution that relates to the larger political and social context in which it exists. Jurisprudence can be divided into categories both by the type of question scholars seek to answer and by the theories of jurisprudence, or schools of thought, regarding how those questions are best answered:

Oliver Eaton Williamson (September 27, 1932 – May 21, 2020) was an American economist, a professor at the University of California, Berkeley, and recipient of the 2009 Nobel Memorial Prize in Economic Sciences, which he shared with Elinor Ostrom.

His contributions to transaction cost economics and the theory of the firm have been influential in the social sciences, law and economics. Williamson described his work as "a blend of soft social science and abstract economic theory".

From an economic perspective, contract theory studies how economic actors can and do construct contractual arrangements, generally in the presence of information asymmetry. Because of its connections with both agency and incentives, contract theory is often categorized within a field known as law and economics. One prominent application of it is the design of optimal schemes of managerial compensation. In the field of economics, the first formal treatment of this topic was given by Kenneth Arrow in the 1960s. In 2016, Oliver Hart and Bengt R. Holmström both received the Nobel Memorial Prize in Economic Sciences for their work on contract theory, covering many topics from CEO pay to privatizations. Holmström focused more on the connection between incentives and risk, while Hart on the unpredictability of the future that creates holes in contracts.

A standard practice in the microeconomics of contract theory is to represent the behaviour of a decision maker under certain numerical utility structures, and then apply an optimization algorithm to identify optimal decisions. Such a procedure has been used in the contract theory framework to several typical situations, labeled moral hazard, adverse selection and signalling. The spirit of these models lies in finding theoretical ways to motivate agents to take appropriate actions, even under an insurance contract. The main results achieved through this family of models involve: mathematical properties of the utility structure of the principal and the agent, relaxation of assumptions, and variations of the time structure of the contract relationship, among others. It is customary to model people as maximizers of some von Neumann–Morgenstern utility functions, as stated by expected utility theory.

In economics and law, exclusive dealing arises when a supplier entails the buyer by placing limitations on the rights of the buyer to choose what, who and where they deal. This is against the law in most countries which include the USA, Australia and Europe when it has a significant impact of substantially lessening the competition in an industry. When the sales outlets are owned by the supplier, exclusive dealing is legal because of vertical integration, where the outlets are independent exclusive dealing is illegal (in the US) due to the Restrictive Trade Practices Act, however, if it is registered and approved it is allowed. While primarily those agreements imposed by sellers are concerned with the comprehensive literature on exclusive dealing, some exclusive dealing arrangements are imposed by buyers instead of sellers.

Exclusive dealing can be considered as a barrier to entry especially in market that operate under imperfect competition, which is either Monopoly or Oligopoly where there is price and product differentiation as well as an imbalance of market power between incumbent, entrants and competitors due to the existing of vertical integrations within the market, leading to market inefficiencies.
