      abstract = {The use of a linear time trend as a proxy for  technological change in economic relationships often leads  to unsatisfactory econometric results. An alternative  procedure based on variational parameter procedures is  proposed and applied to the demand for formula feed, fed to  hogs, in France. The need to incorporate the technological  diffusion process provides the theoretical justification  for the procedures used, while the empirical results are  quite encouraging.},
