Kinked demand curve model explaining oligopoly price rigidity. Adjustable kink price and MC level demonstrate how the vertical MR gap allows cost changes without price adjustment — the core mechanism behind sticky prices in oligopolistic markets.
Simulate protectionist trade policy. Imposing a tariff elevates the world price, mathematically shrinking Consumer Surplus while generating Government Revenue and Deadweight Loss triangles.
Drag the market price line to find the optimal quantity where MR intercepts Marginal Cost. Instantly calculates Total Economic Profit or identifies the Shutdown point when Price falls below AVC.
Understand firm costs in the Long Run. Slide targeted production scales to track how Short-Run Average Total Cost curves (SRATC) form the Returns to Scale envelope.
Graph income inequality mathematically. Bend the Lorenz curve from Perfect Equality to extreme inequality and watch the Gini Coefficient (A/(A+B)) update in real-time.
