Have we missed the right version of the standard Ramsey growth model?

Surprisingly, and as a result of intellectual curiosity, the resolution of the Ramsey growth problem with a Utility function describing relative preferences for consumption and savings, happens to provide formidable results. An advanced microeconomic analysis of this particular assumption which follows consequently, and presumably the sole one of the literature, reveals that it may be a judicious way to formalize the desire of the individual to save each time in the Ramsey model, and to control for the degree of the direct preference for thriftiness implicitly involved. Assuming this more general Utility function shows indeed that the standard Ramsey model widely used in the profession is a particular restrictive case, where basic static properties of the steady state known from the exogenous Solow model (1956), including the one of the golden rule, appear to be missing because of the “constrained” neutrality of this preference.
