''Import variety and productivity in Japan''
( 2009, Vol. 29 No.3 )
This paper constructs import variety indices, as developed by Feenstra (1994), for 21 industries over a twenty year period for Japan. Next, both single-equation and panel regressions of productivity (TFP) on import variety and R&D are conducted. Results find that increased import variety, both own-variety and upstream inputs, positively affect productivity.
Keywords: variety index, imports, growth, TFP, Japan
