  Ramsey’s intuition in moving from Mark I to Mark II was powerful, but in a paper that initiated the modern literature on the Ramsey problem, Chakravarty (1962) observed that to rely exclusively on the condition Ramsey had identified as being necessary for a consumption stream to be the optimum (see below) can lead to absurd results (see below, Sect. 4). In effect Chakravarty observed that infinite integrals, even when cast in the re-normalized form in Ramsey Mark II, don’t necessarily converge to finite values.
