Tinbergen-Solow Production Function
This is a visualization of the Tinbergen–Solow equation. It is a modified version of the Cobb–Douglas production function, with an additional residual term . This function incorporates technological change, which is not reflected in the Cobb–Douglas production function. At a fixed time economic output is still a function of labor and capital , but now as technological progress grows at rate , the attainable economic outputs increase.
