Liberdade económica é fundamental

Do abstract de "Who Creates Jobs? Small vs. Large vs. Young" de John Haltiwanger, Ron S Jarmin e Javier Miranda:
.
"Using data from the Census Bureau Business Dynamics Statistics and Longitudinal Business Database, we explore the many issues regarding the role of firm size and growth that have been at the core of this ongoing debate (such as the role of regression to the mean). We find that the relationship between firm size and employment growth is sensitive to these issues. However, our main finding is that once we control for firm age there is no systematic relationship between firm size and growth. Our findings highlight the important role of business startups and young businesses in U.S. job creation. Business startups contribute substantially to both gross and net job creation. In addition, we find an “up or out” dynamic of young firms. These findings imply that it is critical to control for and understand the role of firm age in explaining U.S. job creation."
