Offprint of Koopmans's paper in which he emphazised the need for identification of parameters, in particular when there is a change in structural paramters between the period of observation and the period to which the prediction applies. ""For example, assume a model that shows consumer's demands for jeans depends on prices and on their income. If there is any change in consumers' preferences, futures expectations, or a change in the tax rate between the period of observation and the period to which the prediction applies, there will certainly be some effect on the parameter values of this model.""
