Taking the U.S. aggregate number as representative, research productivity falls in half every 13 years — ideas are getting harder and harder to find. Put differently, just to sustain constant growth in GDP per person, the U.S. must double the amount of research effort every 13 years to offset the increased difficulty of finding new ideas.”

Evidence from 192 Countries over 2001-2018. “Rather, the evidence shows that the strongest predictors of cross-national variation in entrepreneurial activity were normative, with social norms being the most strongly associated with entrepreneurialism and rates of organizational founding.”

Misallocation arises because high productivity cities like New York and the San Francisco Bay Area have adopted stringent restrictions to new housing supply, effectively limiting the number of workers who have access to such high productivity. Using a spatial equilibrium model and data from 220 metropolitan areas we find that these constraints lowered aggregate US growth by more than 50% from 1964 to 2009.”
