A Philosophical Theory of Quality Time: The Seneca Model

This paper incorporates Seneca’s concept of quality time into the Ramsey model by treating it as a state variable. The resulting framework yields an optimal allocation of time that rises with the utility weight on quality time and falls with its initial stock, impatience, learning costs, and its rate of change. When preferences between quality time and consumption are non-separable, time allocation also increases with consumption. In this case, the Ramsey golden rule no longer holds, optimal consumption, capital, and quality time must be jointly determined—implying that philosophical reflection can shape economic growth, in contrast to Seneca’s original skepticism.
