Tournament Theory
Tournament theory is the theory in personnel economics used to describe certain situations where wage differences are based not on marginal productivity but instead upon relative differences between the individuals. This theory was invented by economists Edward Lazear and Sherwin Rosen.Edward P. Lazear and Sherwin Rosen, 1981. "Rank-Order Tournaments as Optimum Labor Contracts," ''Journal of Political Economy'', 89(5), pp841-864 The theory has been applied to professional sports and to the practice of law. Tournament theory also was applied to writing - one writer may be fractionally better at writing than another (and therefore have a better book), but because people allocate small amounts of time to reading, the writer with the marginally better book will sell far more copies. Rank-Order Tournaments as Optimum Labour Contracts Lazear and Rosen proposed tournament theory in their 1981 paper Rank-Order Tournaments as Optimum Labor Contracts', looking at performance related pay.

Personnel Economics
Personnel economics has been defined as "the application of economic and mathematical approaches and econometric and statistical methods to traditional questions in human resources management". It is an area of applied micro labor economics, but there are a few key distinctions. One distinction, not always clearcut, is that studies in personnel economics deal with the personnel management ''within'' firms, and thus internal labor markets, while those in labor economics deal with labor markets as such, whether external or internal. In addition, personnel economics deals with issues related to both managerial-supervisory and non-supervisory workers. The subject has been described as significant and different from sociological and psychological approaches to the study of organizational behavior and human resource management in various ways. It analyzes labor use, which accounts for the largest part of production costs for most firms, by formulation of relatively simple but generaliza ...

Marginal Productivity
In economics and in particular neoclassical economics, the marginal product or marginal physical productivity of an input (factor of production) is the change in output resulting from employing one more unit of a particular input (for instance, the change in output when a firm's labor is increased from five to six units), assuming that the quantities of other inputs are kept constant. The marginal product of a given input can be expressed as: :MP = \frac where \Delta X is the change in the firm's use of the input (conventionally a one-unit change) and \Delta Y is the change in quantity of output produced (resulting from the change in the input). Note that the quantity Y of the "product" is typically defined ignoring external costs and benefits. If the output and the input are infinitely divisible, so the marginal "units" are infinitesimal, the marginal product is the mathematical derivative of the production function with respect to that input. Suppose a firm's output ''Y'' is ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
The New Palgrave Dictionary Of Economics
''The New Palgrave Dictionary of Economics'' (2018), 3rd ed., is a twenty-volume reference work on economics published by Palgrave Macmillan. It contains around 3,000 entries, including many classic essays from the original Inglis Palgrave Dictionary, and a significant increase in new entries from the previous editions by the most prominent economists in the field, among them 36 winners of the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel.

Edward Lazear
Edward Paul Lazear (, ; August 17, 1948November 23, 2020) was an American economist, the Morris Arnold and Nona Jean Cox Senior Fellow at the Hoover Institution at Stanford University and the Davies Family Professor of Economics at Stanford Graduate School of Business. Lazear served as Chairman of the Council of Economic Advisers from 2006 to 2009. As Chairman, he was the chief economic advisor to President George W. Bush, holding a cabinet-level post as part of the White House team that led the response to the 2007-2008 financial crisis. Lazear has been called the founder of personnel economics a field of economics that applies economic models to the study of the management of human resources in the firm. His research advanced new models of employee incentives, promotions, compensation and productivity in firms. He is also credited with developing a theory of entrepreneurship and leadership that emphasizes skill acquisition. In addition to personnel economics, Lazear was a lab ...

Winner-take-all Market
In economics, a winner-take-all market is a market in which a product or service that is favored over the competitors, even if only slightly, receives a disproportionately large share of the revenues for that class of products or services. It occurs when the top producer of a product earns a lot more than their competitors. Examples of winner-take-all markets include the sports and entertainment markets. The distribution of rewards for different amounts of work determines the degree to which a market is considered winner-take-all. For example, most lottery games are 100% winner-take-all systems because one person takes the entire reward and the rest receive nothing. On the other hand, most manual work, such as picking apples, is the opposite of a winner-take-all system. In this apple-picking example, the reward is proportional to the amount picked — a person who picks only one box of apples still gets rewarded proportionally. There are also intermediate cases. For example, in Ol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Superstar
A superstar is someone who has great popular appeal and is widely known, prominent, or successful in their field. Celebrities referred to as "superstars" may include individuals who work as actors, musicians, athletes, and other media-based professions. History The origin of the term in the context of celebrity is uncertain, but a similar expression is attested in John Nyren's 1832 cricket book '' The Cricketers of My Time''. Nyren described the 18th-century cricketer John Small as "a star of the first magnitude".John Nyren, ''The Cricketers of my Time'', Robson, 1998, p.57. The earliest use of the term "superstar" has been credited to Frank Patrick in reference to the ice hockey players on his Vancouver Millionaires teams of the 1910s and 1920s, specifically Cyclone Taylor. In the June 1977 edition of ''Interview'' magazine, pop artist Andy Warhol was asked by editor Glenn O'Brien who invented the word "superstar". Warhol, known for popularizing the term, responded, "I think ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Long Tail
In statistics and business, a long tail of some probability distribution, distributions of numbers is the portion of the distribution having many occurrences far from the "head" or central part of the distribution. The distribution could involve popularities, random numbers of occurrences of events with various probabilities, etc. The term is often used loosely, with no definition or an arbitrary definition, but precise definitions are possible. In statistics, the term ''long-tailed distribution'' has a narrow technical meaning, and is a subtype of heavy-tailed distribution. Intuitively, a distribution is (right) long-tailed if, for any fixed amount, when a quantity exceeds a high level, it almost certainly exceeds it by at least that amount: large quantities are probably even larger. Note that there is no sense of ''the'' "long tail" of a distribution, but only the ''property'' of a distribution being long-tailed. In business, the term ''long tail'' is applied to rank-size dis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Free-rider Problem
In the social sciences, the free-rider problem is a type of market failure that occurs when those who benefit from resources, public goods (such as public roads or public library), or services of a communal nature do not pay for them or under-pay. Free riders are a problem because while not paying for the good (either directly through fees or tolls or indirectly through taxes), they may continue to access or consume it. Thus, the good may be under-produced, overused or degraded. Additionally, it has been shown that despite evidence that people tend to be cooperative by nature, the presence of free-riders cause this prosocial behaviour to deteriorate, perpetuating the free-rider problem. The free-rider problem in social science is the question of how to limit free riding and its negative effects in these situations. Such an example is the free-rider problem of when property rights are not clearly defined and imposed. The free-rider problem is common with public goods which are n ...
