A Necessary Extension of Economics

Abstract

A leisure term with an unbounded value function, when added to utility in the Lucas (1988) ‘mechanics of economic development’, expands enormously the range of data covered by the theory. To explain this we have to ask two questions. First: why leisure would be so much desired? Perhaps because leisure is one’s own time and such a leisure term means an unbounded value of individual freedom. But why leisure is economically productive, as implied by the results obtained in this study? Perhaps because cognitive innovations often occur during the time which in economics is registered as leisure? Then an unbounded leisure term would also make room for an unbounded creation of knowledge, as distinguished from the mere transmission of knowledge in education and training. But the leisure term is also the ‘hole’ through which the nonmaterial values of the demand side may affect economics.
