[26] [27] In the classic handicap models of begging in game theory, all players are assumed to pay the same amount to produce a signal of a given level of intensity, but differ in the relative value of eliciting the desired response (donation) from the receiver. The hungrier the baby bird, the more food is of value to it, and the higher the ...

[93] [96] [97] Since hunting ability is a prerequisite for marriage, men who are good hunters enter the marriage market earliest. Costly signalling theory explains seemingly wasteful foraging displays. [80]
Michael Spence studies the signalling equilibrium that may result from such a situation. He began his 1973 model with a hypothetical example: [2] suppose that there are two types of employees—good and bad—and that employers are willing to pay a higher wage to the good type than the bad type. Spence assumes that for employers, there's no ...
An employer must be receiving a profit from his operations, so that workers must be producing what Marx (under the labor theory of value) perceived as surplus-value, i.e., doing work beyond that necessary to maintain their labor power. Though having "human capital" gives workers some benefits, they are still dependent on the owners of non-human ...
Phylogenetic signal in continuous traits can be quantified and measured using K-statistic. [3] [15] Within this technique values from zero to infinity are used and higher value also means greater level of phylogenetic signal. [15] The table below shows the most common indices and associated tests used for analyzing phylogenetic signal. [1]
A clash between BlackRock and the FDIC over the money manager’s holdings of US banks will play out in the waning days of President Joe Biden’s administration.
A long thread in economics (from Aristotle to classical economics to the present) distinguishes between exchange value, use value, price, and (sometimes) intrinsic value. It is frequently argued that the connection between price and other types of value is not as direct as suggested in the theory of price signals, other considerations playing a ...
