Constraints to integration into mainstream economy a the country level.

There are significant challenges to giving the creative economy the attention it deserves from mainstream economic philosophy. 

Two main factors are responsible. 

1. First, the quantification limitation of mainstream economic philosophy tends to prefer capturing the direct returns to economic activity, which may not always be captured in creative industries (e.g. approaches to valuing the value-addition of a patent), and can vary significantly due to access to markets, organizational capacity, and commercialization prospects. 
2. The second factor relates to how mainstream economic philosophy captures externalities, which often play an important role in the creative economy, such as cultural exposure, proximity of varying artistic expressions to each other, and the role of demographic factors that influence creative economy prospects.
