Evolution of Smartn Players

To model the evolution of strategic intelligence, player types are drawn from a hierarchy of "smartness" analogous to the levels of iterated rationalizability. Nonrationalizable strategies die out, but when higher levels of smartness incur maintenance costs, being right is always as good as being smart. Moreover, if a manifest way to play emerges, then dumb players never die out, while smarter players with positive maintenance costs vanish. These results call to question the standard game-theoretic assumption of super-intelligent players. Journal of Economic Literature Classification Numbers: B40, C70, C72, C73.     

INCOME AND THE HAMILTONIAN1

Among the many interpretations of real national income are (i) the return to national wealth and (ii) the Hamiltonian of an appropriately-chosen dynamic model of the economy. These interpretations are sometimes alleged to be equivalent and to constitute the self-evidently ideal definition to which statistics of real national income should conform as closely as possible., The allegation is correct on some very restrictive assumptions about technology and taste. Otherwise, these interpretations are inconsistent, inexpedient as definitions of real national income and significantly at variance with the usage in the national accounts. The return to wealth is unmeasurable with the currently-available data. The Hamiltonian is typically in the wrong units. It is an accurate reflection of neither productive capacity nor welfare in an intertemporal context. It is not well-defined in a tax-distorted economy. It is rarely an indicator of the return to wealth.

A personn's income is "the maximum value he can consume during a week and still be as well off at the end of the week as he was at the beginning"
