Does slower labor supply growth explain the decline in startups?
Core argument: The U.S. startup rate fell from 13% in 1979 to 10% by 2007, a decline of nearly 25%, attributed largely to demographic shifts affecting labor supply growth.
The startup rate, which was 13% in 1979 and fell to 10% by 2007, has declined by nearly 25%, largely due to demographic shifts affecting labor supply growth. Since the late 1970s, the slowdown in U.S. labor supply growth explains approximately two-thirds of this decline. This trend is linked to the need for growing labor demand to match labor supply, achievable through either a decrease in real wages or the entry of new firms. The widespread decline in startup rates across markets is attributed to the universal impact of reduced labor force growth. Models of firm dynamics suggest that slower labor supply growth necessitates slower firm entry, leading to a lower startup rate. This demographic-driven explanation aligns well with observed data, highlighting the critical role of labor supply dynamics in shaping the entrepreneurial landscape.
