You might need to clarify exactly what you mean when you ask if anyone has
studied the economics of crop models at the farm level.
The value of a model may, for example, lie in its ability to demonstrate the
actual or potential value of a new management strategy, crop cultivar, or
technology (e.g. use of seasonal forecasts - refer below) over existing
practices - i.e. determine the marginal value of the new relative to current
practices. This can be done at the farm or regional level.
A model may be specific to a particular task or problem, in which case it
might have a lower value than a model which can be used to address a range
of tasks, management or technological opportunities or problems.

growing. Australian Journal of Agricultural Economics, 40, 211–233, 1996.

Dear all,
I am looking for papers (article or conference proceeding) discussing
economical benefits of crop model's use for farming system.
I want to know if anyone had study the economics of crop models at the farm
level.
Thanks for your help.
Apologies for cross listing.
