Age and Farmer Productivity
Tauer, Loren W.
Farmer productivity by age was estimated, allowing for differences because of efficiency and returns to scale. Using Census of Agriculture data, estimates vary by state, but returns to scale average 1.07. Efficiency increases average 4.5 percent every ten years of age, to the age interval 35 to 44, and then decreases at that same rate.
