Cobb-Douglas Production Surface

Interactive 3D Cobb-Douglas production function Y = A·K^α·L^(1-α): drag capital and labor to watch output climb a diminishing-returns surface, trace the isoquant through your point, and test returns to scale by doubling both inputs at once.

This simulator turns the Cobb-Douglas production function Y = A·K^α·L^(1-α) into an interactive 3D surface. Drag capital and labor to move a marker across the terrain and watch output, along with the marginal product of each input, update live. Toggle the isoquant to trace every input mix that yields today's exact output, and use the scale buttons to test returns to scale directly by doubling or halving both inputs at once.
