Energy Input Interaction in US Output

open access: yesReview of Economic Analysis, 2022
This paper estimates production functions for annual US output from 1949 to 2013 adding energy Btu input to fixed capital assets and the labor force.  Interactions between inputs are parsimoniously introduced in the error correction estimates.  Fixed capital assets successfully imbed technology.

Green urbanization.

open access: yesPLoS ONE, 2021
Large cities are more productive and generate more output per person. Using data from the UK on energy demand and waste generation, we show that they are also more energy-efficient. Large cities are therefore greener than small towns.

Energy Intake, Not Energy Output, Is a Determinant of Body Size in Infants [PDF]

open access: yesJournal of the American Academy of Child & Adolescent Psychiatry, 1999
It has been proposed that the primary determinants of body weight at 1 y of age are genetic background, as represented by parental obesity, and low total energy expenditure.The objective was to determine the relative contributions of genetic background and energy intake and expenditure as determinants of body weight at 1 y of age.Forty infants of obese
