Elasticity may refer to:
• Elasticity (physics)
Elasticity (physics)
In physics, elasticity is the physical property of a material that returns to its original shape after the stress that made it deform or distort is removed. The relative amount of deformation is called the strain....

, continuum mechanics of bodies that deform reversibly under stress

Numerous uses are derived from this physical sense of the term, which is inherently mathematical, such as used in Engineering, Chemistry, Construction and variously in Economics:
• Elasticity (data store)
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 data store is considered to be.-Clustering...

, the flexibility of the data model
Data model
A data model in software engineering is an abstract model, that documents and organizes the business data for communication between team members and is used as a plan for developing applications, specifically how data is stored and accessed....

and the clustering
Clustering
Clustering can refer to the following:In demographics:* Clustering , the gathering of various populations based on factors such as ethnicity, economics or religion.In graph theory:...

• Elasticity (economics)
Elasticity (economics)
In economics, elasticity is the measurement of how changing one economic variable affects others. For example:* "If I lower the price of my product, how much more will I sell?"* "If I raise the price, how much less will I sell?"...

, a general term for a ratio of change. For more specific economic forms of elasticity, see:
• Beta coefficient
Beta coefficient
In finance, the Beta of a stock or portfolio is a number describing the relation of its returns with those of the financial market as a whole.An asset has a Beta of zero if its returns change independently of changes in the market's returns...

• Cross elasticity of demand
Cross elasticity of demand
In economics, the cross elasticity of demand or cross-price elasticity of demand measures the responsiveness of the demand for a good to a change in the price of another good. It is measured as the percentage change in demand for the first good that occurs in response to a percentage change in...

• Elasticity of substitution
Elasticity of substitution
Elasticity of substitution is the elasticity of the ratio of two inputs to a production function with respect to the ratio of their marginal products . It measures the curvature of an isoquant and thus, the substitutability between inputs , i.e...

• Frisch elasticity of labor supply
Frisch elasticity of labor supply
Named after Ragnar Frisch, the Frisch elasticity of labor supply captures the elasticity of hours worked to the wage rate, given a constant marginal utility of consumption. In other words, Frisch elasticity measures the substitution effect of a change in the wage rate on labor supply. -References:*...

• Income elasticity of demand
• Output elasticity
Output elasticity
In economics, output elasticity is the percentage change of output divided by the percentage change of an input. It is sometimes called partial output elasticity to clarify that it refers to the change of only one input....

• Price elasticity of demand
Price elasticity of demand
Price elasticity of demand is a measure used in economics to show the responsiveness, or elasticity, of the quantity demanded of a good or service to a change in its price. More precisely, it gives the percentage change in quantity demanded in response to a one percent change in price...

• Price elasticity of supply
Price elasticity of supply
Price elasticity of supply 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....

• Yield elasticity of bond value
Yield elasticity of bond value
Yield elasticity of bond value is the percentage change in bond value divided by a one per percentage change in the yield to maturity of the bond. This is equivalent to saying the derivative of value with respect to yield times the...
