Abstract:
An identical two-sector productivity shock causes Rybczynski (1955) and Stolper and Samuelson (1941) effects that release leisure time and initially raise the relative price of human capital investment so as to favor it over goods production. Modified by having the household sector produce human capital investment sector, the RBC model follows the international approach of Maffezzoli (2000) and so adds a second sector relative to Jones et al. (2005). This captures key major US RBC data: output growth persistence, with hump-shaped impulse responses; hump-shaped physical capital investment impulse responses; Gali's (1999) negative impulse response of labour supply; and hours volatility.
