The authors investigate how increases in publication delays have affected the life-cycle of publications of recent Ph.D. graduates in economics. They construct a panel dataset of 14,271 individuals who were awarded Ph.D.s between 1986 and 2000 in US and Canadian economics departments. For this population of scholars, they amass complete records of publications in peer reviewed journals listed in the JEL (a total of 368,672 observations). They find evidence of significantly diminished productivity in recent relative to earlier cohorts when productivity of an individual is measured by the number of AER equivalent publications.
