Elasticity (physics)
In physics and materials science, elasticity is the ability of a body to resist a distorting influence and to return to its original size and shape when that influence or force is removed. Solid objects will deform when adequate loads are ap ...
, continuum mechanics of bodies that deform reversibly under stress
Elasticity may also refer to:

Elasticity (data store) The elasticity of a data store relates to the flexibility of its data model and clustering capabilities. The greater the number of data model changes that can be tolerated, and the more easily the clustering can be managed, the more elastic the dat ...
, the flexibility of the data model and the clustering

Elasticity (economics)
In economics, elasticity measures the percentage change of one economic variable in response to a percentage change in another. If the price elasticity of the demand of something is -2, a 10% increase in price causes the demand quantity to fall b ...

Beta (finance)
In finance, the beta (β or market beta or beta coefficient) is a measure of how an individual asset moves (on average) when the overall stock market increases or decreases. Thus, beta is a useful measure of the contribution of an individual as ...

Elasticity of substitution Elasticity of substitution is the ratio of percentage change in capital-labour ratio with the percentage change in Marginal Rate of Technical Substitution. In a competitive market, it measures the percentage change in the two inputs used in respons ...

Frisch elasticity of labor supply The Frisch elasticity of labor supply captures the elasticity of hours worked to the wage rate, given a constant marginal utility of wealth. Marginal utility is constant for risk-neutral individuals according to microeconomics. In other words, the ...

Income elasticity of demand
In economics, the income elasticity of demand is the responsivenesses of the quantity demanded for a good to a change in consumer income. It is measured as the ratio of the percentage change in quantity demanded to the percentage change in incom ...
*
Output elasticity In economics, output elasticity is the percentage change of output (GDP
Gross domestic product (GDP) is a monetary measure of the market value of all the final goods and services produced and sold (not resold) in a specific time period by ...
*
Price elasticity of demand
A good's price elasticity of demand (E_d, PED) is a measure of how sensitive the quantity demanded is to its price. When the price rises, quantity demanded falls for almost any good, but it falls more for some than for others. The price elastici ...
*
Price elasticity of supply
The price elasticity of supply (PES or Es) is a measure used in economics to show the responsiveness, or elasticity, of the quantity supplied of a good or service to a change in its price.
The elasticity is represented in numerical form, and ...
*
Yield elasticity of bond value
The yield elasticity of bond value is the elasticity of the market value of a bond with respect to its yield—the percentage change in bond value divided by its causative percent change in the yield to maturity of the bond. Equivalently, it is ...

Elasticity of a function In mathematics, the elasticity or point elasticity of a positive differentiable function ''f'' of a positive variable (positive input, positive output) at point ''a'' is defined as
:Ef(a) = \fracf'(a)
:=\lim_\frac\frac=\lim_\frac\frac=\lim_\frac\ap ...
, a mathematical definition of point elasticity
*
Arc elasticity In mathematics and economics, the arc elasticity is the elasticity of one variable with respect to another between two given points. It is the ratio of the percentage change of one of the variables between the two points to the percentage change of ...
