Pricing Strategy for a demand shock

Simulate a demand shock live in your browser. This runs the real Pricing Strategy solver — adjust the inputs, watch it respond instantly, and export the result. No install, no account.

Price Elasticity of DemandLive

Controls

Presets

Elasticity measures how much quantity demanded responds to price. Where demand is elastic (|E| > 1), a price cut raises total revenue; where it is inelastic, a price cut lowers revenue. On a straight-line demand curve the top half is elastic, the bottom half inelastic, and revenue peaks exactly at the midpoint where elasticity equals one.

Elasticity-1.00

Revenue$2500

Governing equation

Reading this result: You are at the unit-elastic midpoint: revenue is at its maximum, and small price moves in either direction leave it roughly unchanged.

Monopoly PricingLive

Controls

Presets

A monopolist maximizes profit where marginal revenue equals marginal cost — then charges the price the demand curve allows. Because MR lies below demand, the monopoly produces less and charges more than a competitive market (where price equals MC). The red triangle is the deadweight loss: mutually beneficial trades that never happen.

▶ Run in Python

Data Inspector

Monopoly price$65.0
Monopoly qty35.0
Competitive qty70.0
Deadweight loss613
Profit1225

Governing equation

Reading this result: At MC = $30, the monopolist makes 35 units and charges $65 — a $35 markup over cost. That output is exactly half the competitive 70, and the shaded triangle (613) is the welfare lost to that restraint.

About this simulation

The full Pricing Strategy tool models a demand shock with the same numerics engineers and scientists use — running entirely client-side. Change any parameter and the result updates in real time, so you can build intuition, check a design, or teach the concept without spreadsheets or installs.
