Transition Dynamics in Vintage Capital Models: Explaining the Postwar Catchup of Germany and Japan

Working Paper: NBER ID: w10732

Authors: Simon Gilchrist; John C. Williams

Abstract: We consider a neoclassical interpretation of Germany and Japan's rapid postwar growth that relies on a catch-up mechanism through capital accumulation where technology is embodied in new capital goods. Using a putty-clay model of production and investment, we are able to capture many of the key empirical properties of Germany and Japan's postwar transitions, including persistently high but declining rates of labor and total-factor productivity growth, a U-shaped response of the capital-output ratio, rising rates of investment and employment, and moderate rates of return to capital.
