Abstract
A model of energy analysis is presented to study the concept of labor productivity from a biophysical perspective. It is argued that current methods of defining and assessing labor productivity in the fields of work physiology and input/output energy analysis are relatively poor operational tools for assessing productivity in the economy and society. We propose to adopt society as the hierarchical level of analysis rather than the individual, as labor productivity can best be studied as a function of parameters related to the technological development of society. Parameters considered are: the ratio exosomatic/endosomatic energy used in society, the ratio working/non-working population, the return on the circulating energy investment, and the profile of human time allocated to the economic process. The links between patterns of human time allocation, population structure, standard of living, technological development, and demand on natural resources are analyzed. The results suggest that the role and meaning of human labor differ widely in societies with different levels of technological development.
