Translated to a cross-country context, the Solow model (Solow, 1956) predicts that international
differences in steady-state output per person are due to international differences in technology for a constant
capital–output ratio. However, most of the empirical growth literature that refers to the Solow model
has employed a specification where steady-state differences in output per person are due to international
differences in the capital–output ratio for a constant level of technology.
