Since the publication of Keynes' General Theory economists have treated the demand for particular forms of wealth as a problem in portfolio balance. The later development of the Human Capital approach essentially elaborated on this analysis by extending the choice of forms in which to hold wealth, and also stimulated interest in the mechanism of parental finance of the human capital investments (Becker, 1967) For this reason, human capital models are antecedents of intergenerational models of the demand for wealth and the composition of wealth.
