Why Choice Makes People Miserable:
Pareto distribution
The Pareto distribution, named after the Italian civil engineer, economist, and sociologist Vilfredo Pareto, is a power law probability distribution that is used in description of social, scientific, geophysical, actuarial, and many other types of observable phenomena. Definition[edit] If X is a random variable with a Pareto (Type I) distribution,[1] then the probability that X is greater than some number x, i.e. the survival function (also called tail function), is given by where xm is the (necessarily positive) minimum possible value of X, and α is a positive parameter. Properties[edit] Cumulative distribution function[edit] From the definition, the cumulative distribution function of a Pareto random variable with parameters α and xm is When plotted on linear axes, the distribution assumes the familiar J-shaped curve which approaches each of the orthogonal axes asymptotically. Probability density function[edit] It follows (by differentiation) that the probability density function is Suppose
Pareto Optimal | Pareto Efficient | Pareto Improvement | Pareto Tutorial
Pareto Efficient and Pareto Optimal Tutorial The main tenant of economics is that resources are scarce. Due to scarcity, that means that not everyone can have some of everything, leading to competition. Pareto Efficiency Named for an Italian economist who specialized in resource and income allocation, Pareto Efficiency goes hand in hand with the Pareto Optimal concept. Through making Pareto Improvements, overall social utility can be increased, by seeking to make allocation decisions that minimize decreased utility for other individuals in the efforts to increase one individual’s utility. What is Pareto Optimality Looking at a standard production possibilities frontier, all points that lie under the curve are inefficient allocations. Pareto Optimality is used heavily in political economics as a means to distribute resources in a more efficient manner to increase overall social utility. ShareThis
Opportunity cost
History[edit] The term was first used in 1914 by Austrian economist Friedrich von Wieser in his book Theorie der gesellschaftlichen Wirtschaft [4] (Theory of Social Economy). The idea had been anticipated by previous writers including Benjamin Franklin and Frédéric Bastiat. Franklin coined the phrase "Time is Money", and spelt out the associated opportunity cost reasoning in his “Advice to a Young Tradesman” (1746): “Remember that Time is Money. He that can earn Ten Shillings a Day by his Labour, and goes abroad, or sits idle one half of that Day, tho’ he spends but Sixpence during his Diversion or Idleness, ought not to reckon That the only Expence; he has really spent or rather thrown away Five Shillings besides.” Bastiat's 1848 essay "What Is Seen and What Is Not Seen" used opportunity cost reasoning in his critique of the broken window fallacy, and of what he saw as spurious arguments for public expenditure.

Vilfredo Pareto
Vilfredo Federico Damaso Pareto (born Wilfried Fritz Pareto; Italian: [vilˈfreːdo paˈreːto]; 15 July 1848 – 19 August 1923) was an Italian engineer, sociologist, economist, political scientist, and philosopher. He made several important contributions to economics, particularly in the study of income distribution and in the analysis of individuals' choices. He was also responsible for popularising the use of the term "elite" in social analysis. He introduced the concept of Pareto efficiency and helped develop the field of microeconomics. His legacy as an economist was profound. Biography[edit] Pareto was born of an exiled noble Genoese family in 1848 in Paris, the centre of the popular revolutions of that year. From Civil engineer to liberal, and then to economist[edit] For some years after graduation, he worked as a civil engineer, first for the state-owned Italian Railway Company and later in private industry. He did not begin serious work in economics until his mid-forties.

Howard Moskowitz
Howard Moskowitz is an American market researcher and psychophysicist. He is best known for the detailed study he made of the types of spaghetti sauce and horizontal segmentation. By providing a large number of options for consumers, Moskowitz pioneered the idea of intermarket variability as applied to the food industry.[1] Howard Moskowitz is the CEO of i-Novation Inc as well as President of Moskowitz Jacobs Inc., a firm he founded in 1981. Dr. His latest book with co-author Alex Gofman, Selling Blue Elephants [2] demonstrates and popularizes how IdeaMap (i-Novation`s flagship product) creates new products and messages... from areas as diverse as credit cards, jewelry offers, presidential messaging during election years, stock market communications, and trans-national innovation. Moskowitz has won the Scientific Director`s Gold Medal for outstanding research at the U.S. In 2005, Dr. Products[edit] See also[edit] References[edit] External links[edit]
Henri Lefebvre
Henri Lefebvre (French: [ləfɛvʁ]; 16 June 1901 – 29 June 1991) was a French Marxist philosopher and sociologist, best known for pioneering the critique of everyday life, for introducing the concepts of the right to the city and the production of social space, and for his work on dialectics, alienation, and criticism of Stalinism and structuralism. In his prolific career, Lefebvre wrote more than sixty books and three hundred articles.[1] Biography[edit] In 1961, Lefebvre became professor of sociology at the University of Strasbourg, before joining the faculty at the new university at Nanterre in 1965.[7] He was one of the most respected professors, and he had influenced and analysed the May 1968 students revolt.[8] Lefebvre introduced the concept of the right to the city in his 1968 book Le Droit à la ville[9][10] (the publication of the book predates the May 1968 revolts which took place in many French cities). Lefebvre died in 1991. The critique of everyday life[edit] "Change life!
Psychophysics
Psychophysics also refers to a general class of methods that can be applied to study a perceptual system. Modern applications rely heavily on threshold measurement,[3] ideal observer analysis, and signal detection theory.[4] Psychophysics has widespread and important practical applications. As just one example, in the study of digital signal processing, psychophysics has informed the development of models and methods of lossy compression. History[edit] Many of the classical techniques and theories of psychophysics were formulated in 1860 when Gustav Theodor Fechner in Leipzig published Elemente der Psychophysik.[5] He coined the term "psychophysics", describing research intended to relate physical stimuli to the contents of consciousness such as sensations (Empfindungen). Fechner's work was studied and extended by Charles S. Omar Khaleefa[14] has argued that the medieval scientist Alhazen should be considered the founder of psychophysics.
