Nonseparable Models*

When confronting an economic model with data, one is typically faced with the problem that some of the important variables in the model are unobservable.Rather than transforming the model into a different one that describes only the relationship among the observable variables, this research studies identification and estimation of the original model.The resulting model will typically be more complex, because it includes unobservable variables in nonlinear and possible nested ways.On the other hand, because the unobservable variables have economic content, one can exploit the properties that the economic model implies on those variables.
