      abstract = {This paper presents an alternative approach to the  measurement of technical change. It is based on the latent  variable level
of technology that enters explicitly the  input demand system and on a hypothesis about the  innovation generating process. By
adding measurement error  equations, the behavioral system can be viewed as a  Multiple Indicators/Multiple Causes (MIMIC)
model. The  parameter estimates are obtained with a maximum likelihood  estimator which involves the implicit covariance
matrix.  The analysis refers to Italian agriculture and the results  provide some evidence on the nature and level of  technical
change during the years 1961-1991. © 2000  Elsevier Science B.V. All rights reserved.},
