Simple replacing of goods are adversely correlated which have creativity items, whenever you are a constant arrival out of fighting facts was seriously coordinated with device invention. Brief obsolescence of products is undoubtedly synchronised to help you RD and you can adversely coordinated in order to process innovation. Rapid alterations in creation tech likewise have a powerful positive correlation which have development facts.

Correa ( 2012 ) finds an architectural get down the data test employed by Aghion ainsi que al. ( 2005 ). Depending on just what time frame the content is taken from, other relationship are found to exist.

step one.5. The new upside down-You matchmaking

Whenever businesses contrast the expected pre- and you can blog post-creativity rents, and you can on the other hand run away race, you get behaviors that make a non-linear dating (Aghion et al., 2005 ).
