Elasticities of demand
Price animation of demand
Main article: Bulk animation of demand
Bulk animation of appeal measures the allotment change in abundance accepted acquired by a percent change in price. As such, it measures the admeasurement of movement forth the appeal curve. This animation is about consistently abrogating and is usually bidding in agreement of complete bulk (i.e. as absolute numbers) back the abrogating can be assumed. In these terms, then, if the animation is greater than 1 appeal is said to be elastic; amid aught and one appeal is breakable and if it equals one, appeal is unit-elastic. A altogether adaptable appeal ambit is accumbent (with an animation of infinity) admitting a altogether breakable appeal ambit is vertical (with an animation of 0).
Income animation of demand
Main article: Assets animation of demand
Assets animation of appeal measures the allotment change in appeal acquired by a percent change in income. A change in assets causes the appeal ambit to about-face absorption the change in demand. IED is a altitude of how far the ambit accouterment angular forth the X-axis. Assets animation can be acclimated to allocate appurtenances as accustomed or inferior. With a accustomed acceptable appeal varies in the aforementioned administration as income. With an inferior acceptable appeal and assets move in adverse directions.2
Cross bulk animation of demand
Main article: Cross bulk animation of demand
Cross bulk animation of appeal measures the allotment change in appeal for a accurate acceptable acquired by a percent change in the bulk of addition good. Appurtenances can be complements, substitutes or unrelated. A change in the bulk of a accompanying acceptable causes the appeal ambit to about-face absorption a change in appeal for the aboriginal good. Cross bulk animation is a altitude of how far, and in which direction, the ambit accouterment angular forth the x-axis. A absolute cross-price animation agency that the appurtenances are acting goods.
Cross animation of appeal amid firms
Main article: Academic variation
Cross animation of appeal for firms, sometimes referred to as academic variation, is a admeasurement of the alternation amid firms. It captures the admeasurement to which one close reacts to changes in cardinal variables (price, quantity, location, advertising, etc.) fabricated by added firms.
Elasticity of intertemporal substitution
Main article: Animation of intertemporal substitution
Combined Effects
It is accessible to accede the accumulated furnishings of two or added account of demand. The accomplish are as follows: PED = (∆Q/∆P) x P/Q. Convert this to the predictive equation: ∆Q/Q = PED(∆P/P) if you ambition to acquisition the accumulated aftereffect of changes in two or added determinants of appeal you artlessly add the abstracted effects: ∆Q/Q = PED(∆P/P) + YED(∆Y/Y)12
Remember you are still alone because the aftereffect in appeal of a change in two of the variables. All added variables charge be captivated constant. Note additionally that graphically this botheration would absorb a about-face of the ambit and a movement forth the confused curve.

Price animation of supply
Main article: Bulk animation of supply
The bulk animation of accumulation measures how the bulk of a acceptable firms ambition to accumulation changes in acknowledgment to a change in price.3 In a address akin to the bulk animation of demand, it captures the admeasurement of movement forth the accumulation curve. If the bulk animation of accumulation is aught the accumulation of a acceptable supplied is "inelastic" and the abundance supplied is fixed.
Elasticities of scale
Main article: Allotment to scale
Animation of calibration or achievement elasticities admeasurement the allotment change in achievement induced by a percent change in inputs.4 A assembly action or action is said to display connected allotment to calibration if a allotment change in inputs after-effects in an according allotment in outputs (an animation according to 1). It exhibits accretion allotment to calibration if a allotment change in inputs after-effects in greater allotment change in achievement (an animation greater than 1). The analogue of abbreviating allotment to calibration is analogous.5
