Rational Agent
A rational agent or rational being is a person or entity that always aims to perform optimal actions based on given premises and information. A rational agent can be anything that makes decisions, typically a person, firm, machine, or software. The concept of rational agents can be found in various disciplines such as artificial intelligence, cognitive science, decision theory, economics, ethics, game theory, and the study of practical reason. Economics In reference to economics, rational agent refers to hypothetical consumers and how they make decisions in a free market. This concept is one of the assumptions made in neoclassical economic theory. The concept of economic rationality arises from a tradition of marginal analysis used in neoclassical economics. The idea of a rational agent is important to the philosophy of utilitarianism, as detailed by philosopher Jeremy Bentham's theory of the felicific calculus, also known as the hedonistic calculus. The action a rational ag ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Optimization (mathematics)
Mathematical optimization (alternatively spelled ''optimisation'') or mathematical programming is the selection of a best element, with regard to some criterion, from some set of available alternatives. It is generally divided into two subfields: discrete optimization and continuous optimization. Optimization problems of sorts arise in all quantitative disciplines from computer science and engineering to operations research and economics, and the development of solution methods has been of interest in mathematics for centuries. In the more general approach, an optimization problem consists of maximizing or minimizing a real function by systematically choosing input values from within an allowed set and computing the value of the function. The generalization of optimization theory and techniques to other formulations constitutes a large area of applied mathematics. More generally, optimization includes finding "best available" values of some objective function given a defi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Jeremy Bentham
Jeremy Bentham (; 15 February 1748 [Old Style and New Style dates, O.S. 4 February 1747] – 6 June 1832) was an English philosopher, jurist, and social reformer regarded as the founder of modern utilitarianism. Bentham defined as the "fundamental axiom" of his philosophy the principle that "it is the greatest happiness of the greatest number that is the measure of right and wrong." He became a leading theorist in Anglo-Americans, Anglo-American philosophy of law, and a political radical whose ideas influenced the development of welfarism. He advocated Individualism, individual and economic freedoms, the separation of church and state, freedom of expression, equal rights for women, the right to divorce, and (in an unpublished essay) the decriminalising of homosexual acts. He called for the abolition of abolitionism, slavery, capital punishment#Abolition of capital punishment, capital punishment and physical punishment, including that of children. He has also become known as an ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychology
Psychology is the science, scientific study of mind and behavior. Psychology includes the study of consciousness, conscious and Unconscious mind, unconscious phenomena, including feelings and thoughts. It is an academic discipline of immense scope, crossing the boundaries between the Natural science, natural and social sciences. Psychologists seek an understanding of the Emergence, emergent properties of brains, linking the discipline to neuroscience. As social scientists, psychologists aim to understand the behavior of individuals and groups.Fernald LD (2008)''Psychology: Six perspectives'' (pp.12–15). Thousand Oaks, CA: Sage Publications.Hockenbury & Hockenbury. Psychology. Worth Publishers, 2010. Psi (Greek), Ψ (''psi''), the first Greek alphabet, letter of the Greek word ''psyche'' from which the term psychology is derived (see below), is commonly associated with the science. A professional practitioner or researcher involved in the discipline is called a psychologist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Neuroscience
Neuroscience is the science, scientific study of the nervous system (the brain, spinal cord, and peripheral nervous system), its functions and disorders. It is a Multidisciplinary approach, multidisciplinary science that combines physiology, anatomy, molecular biology, developmental biology, cytology, psychology, physics, computer science, chemistry, medicine, statistics, and Mathematical Modeling, mathematical modeling to understand the fundamental and emergent properties of neurons, glia and neural circuits. The understanding of the biological basis of learning, memory, behavior, perception, and consciousness has been described by Eric Kandel as the "epic challenge" of the Biology, biological sciences. The scope of neuroscience has broadened over time to include different approaches used to study the nervous system at different scales. The techniques used by neuroscientists have expanded enormously, from molecular biology, molecular and cell biology, cellular studies of indivi ...

Neuroeconomics
Neuroeconomics is an interdisciplinary field that seeks to explain human decision-making, the ability to process multiple alternatives and to follow through on a plan of action. It studies how economic behavior can shape our understanding of the brain, and how neuroscientific discoveries can guide models of economics.Center for Neuroeconomics Study at Duke University http://dibs.duke.edu/research/d-cides/research/neuroeconomics It combines research from neuroscience, experimental and behavioral economics, and cognitive and social psychology. As research into decision-making behavior becomes increasingly computational, it has also incorporated new approaches from theoretical biology, computer science, and mathematics. Neuroeconomics studies decision-making by using a combination of tools from these fields so as to avoid the shortcomings that arise from a single-perspective approach. In mainstream economics, expected utility (EU) and the concept of rational agents are s ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Marketing
Marketing is the process of exploring, creating, and delivering value to meet the needs of a target market in terms of goods and services; potentially including selection of a target audience; selection of certain attributes or themes to emphasize in advertising; operation of advertising campaigns; attendance at trade shows and public events; design of products and packaging attractive to buyers; defining the terms of sale, such as price, discounts, warranty, and return policy; product placement in media or with people believed to influence the buying habits of others; agreements with retailers, wholesale distributors, or resellers; and attempts to create awareness of, loyalty to, and positive feelings about a brand. Marketing is typically done by the seller, typically a retailer or manufacturer. Sometimes tasks are contracted to a dedicated marketing firm or advertising agency. More rarely, a trade association or government agency (such as the Agricultural Marketing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Evolutionary Economics
Evolutionary economics is part of mainstream economics as well as a heterodox school of economic thought that is inspired by evolutionary biology. Much like mainstream economics, it stresses complex interdependencies, competition, growth, structural change, and resource constraints but differs in the approaches which are used to analyze these phenomena. Some scholars prefer to call their evolutionary theory by a different names. Samuel Bowles named it "evolutionary social science" and Joachim Rennstich called it "evolutionary systems theory". Evolutionary economics deals with the study of processes that transform economy for firms, institutions, industries, employment, production, trade and growth within, through the actions of diverse agents from experience and interactions, using evolutionary methodology. Evolutionary economics analyzes the unleashing of a process of technological and institutional innovation by generating and testing a diversity of ideas which discover and ...

Institutional Economics
Institutional 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.g. individuals, firms, states, social norms). The earlier tradition continues today as a leading heterodox approach to economics.Warren J. Samuels ( 9872008). "institutional economics," '' The New Palgrave: A Dictionary of Economics''Abstract. "Traditional" institutionalism rejects the ''reduction'' of institutions to simply tastes, technology, and nature (see naturalistic fallacy). Tastes, along with expectations ...

Thorstein Veblen
Thorstein Bunde Veblen (July 30, 1857 – August 3, 1929) was a Norwegian-American economist and sociologist who, during his lifetime, emerged as a well-known critic of capitalism. In his best-known book, ''The Theory of the Leisure Class'' (1899), Veblen coined the concepts of ''conspicuous consumption'' and '' conspicuous leisure''. Historians of economics regard Veblen as the founding father of the institutional economics school. Contemporary economists still theorize Veblen's distinction between "institutions" and "technology", known as the Veblenian dichotomy. As a leading intellectual of the Progressive Era in the US, Veblen attacked production for profit. His emphasis on conspicuous consumption greatly influenced economists who engaged in non-Marxist critiques of fascism, capitalism, and of technological determinism. Biography Early life and family background Veblen was born on July 30, 1857, in Cato, Wisconsin, to Norwegian-American immigrant parents, Thomas ...

Heterodox
In religion, heterodoxy (from Ancient Greek: , "other, another, different" + , "popular belief") means "any opinions or doctrines at variance with an official or orthodox position". Under this definition, heterodoxy is similar to unorthodoxy, while the adjective 'heterodox' could be applied to a dissident. Heterodoxy is also an ecclesiastical term of art, defined in various ways by different religions and churches. For example, in the apostolic churches (the Eastern Orthodox Church, the Roman Catholic Church, the Church of the East, the Anglican Communion, and the Oriental Orthodox Churches), heterodoxy may describe beliefs that differ from strictly orthodox views, but that fall short either of formal or of material heresy. Christianity Eastern Orthodoxy In the Eastern Orthodox Church, the term is used primarily in reference to Christian churches and denominations not belonging to the communion of Eastern Orthodox churches and espousing doctrines contrary to the received Holy ...

Traveler's Dilemma
In game theory, the traveler's dilemma (sometimes abbreviated TD) is a non-zero-sum game in which each player proposes a payoff. The lower of the two proposals wins; the lowball player receives the lowball payoff plus a small bonus, and the highball player receives the same lowball payoff, minus a small penalty. Surprisingly, the Nash equilibrium is for both players to aggressively lowball. The traveler's dilemma is notable in that naive play appears to outperform the Nash equilibrium; this apparent paradox also appears in the centipede game and the finitely-iterated prisoner's dilemma. Formulation The original game scenario was formulated in 1994 by Kaushik Basu and goes as follows: "An airline loses two suitcases belonging to two different travelers. Both suitcases happen to be identical and contain identical antiques. An airline manager tasked to settle the claims of both travelers explains that the airline is liable for a maximum of $100 per suitcase—he is unable to find o ...

Bounded Rationality
Bounded rationality is the idea that rationality is limited when individuals make decisions, and under these limitations, rational individuals will select a decision that is satisfactory rather than optimal. Limitations include the difficulty of the problem requiring a decision, the cognitive capability of the mind, and the time available to make the decision. Decision-makers, in this view, act as satisficers, seeking a satisfactory solution, with everything that they have at the moment rather than an optimal solution. Therefore, humans do not undertake a full cost-benefit analysis to determine the optimal decision, but rather, choose an option that fulfils their adequacy criteria. An example of this being within organisations when they must adhere to the operating conditions of their company, this has the opportunity to result in bounded rationality as the organisation is not able to choose the optimal option. Some models of human behavior in the social sciences assume that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
