Growth Convergence Simulator

A grid of eighteen independent economies, each running the Solow growth model on its own randomized starting capital per worker, rendered as a live 3D bar field. Every "year" each bar's height updates from the discrete law k(t+1) = k(t) + s·k(t)^α − (δ+n)·k(t), so bars that start low climb fastest — diminishing returns to capital mean a capital-poor economy earns more output per extra unit invested than a capital-rich one. Toggle heterogeneous savings rates to switch between absolute convergence (every bar settles at the same height) and conditional convergence (two groups settle at two different steady states), while live readouts track the average capital per worker, the cross-economy dispersion, and the theoretical steady state.
