Supply Elasticity along a Linear Supply Curve (Point Method)


Drag the control points of the supply curve to change its slope.

Drag the price up and down to see how the quantity supplied changes,
and to see how the elasticity calculations change as you move along the supply curve.


\color{ {{ color('green') }} }{\frac{\Delta Q^S}{\Delta P} = \frac{ {{ params.supplyCurveQ2 | number:0 }} - {{ params.supplyCurveQ1 | number:0 }} }{ {{ params.supplyCurveP2 | number: 0 }} - {{params.supplyCurveP1 | number:0}} } =\frac{ {{ params.supplyCurveQ2 - params.supplyCurveQ1 | number:0 }} }{ {{ params.supplyCurveP2 - params.supplyCurveP1 | number:0}} } = {{ model.priceQuantityRelationshipFunction.inverseSlope | extendedReal:2 }}}


\epsilon_{Q^S,P} = \frac{P}{ \color{ {{ color('supply') }} }{Q^S(P)} } \times \color{ {{ color('green') }} }{ \frac{\Delta Q^S}{\Delta P} } || = \frac{ {{ params.price | number:0 }} }{ \color { {{ color('supply') }} } { {{ model.quantityAtPrice(params.price) | number:1 }} } } \times \color{ {{ color('green') }} }{ {{ model.inverseSlope | number:2 }} } || = {{ model.priceElasticity(params.price).elasticityNumber() }}


\left| \epsilon_{Q^S,P} \right| = {{ model.priceElasticity(params.price).elasticityComparator}} \Rightarrow \text{ {{ model.priceElasticity(params.price).elasticityWord }}}
