Abstract

Traditional total factor productivity [TFP] misrepresents the true change in agricultural productivity to the extent that environmental bads jointly produced with desirable outputs are unaccounted. Nonparametric productivity measures incorporating environmental bads are evaluated for Nebraska agriculture. The results indicate that prior to the 1980's the traditional TFP measures overstate productivity growth while it is underestimated afterwards, reflecting peak use of chemicals.
