Scientific paper contribution 1: Primary Energy Analysis: A New Approach beyond Extant Growth Theories
This paper is co-authored by Nobuo Kawamiya.

Abstract: A best possible indicator to represent the whole economic activity should be not the GDP but "the whole industrial production (WIP)" because the former represents only the added value sector of an economy, while the latter comprises both the GDP and all intermediate throughputs in the economy. The historical change of WIP compared with the primary energy supply (PES) in Japan revealed a close structural correlation between WIP and PES: Japan’s once rapid growth had a remarkable feature that a sharp rise of the PES occurred during 1955-1973 and that of the WIP, during 1965-1985, with a clear time-lag of ten years or so. And the dual stagnation of PES and WIP has deeply rooted in Japan’s economy since the bubble burst in 1990. This serious economic frustration has long been regarded as peculiar to Japan but, since the Lehman shock, such a situation has suddenly become a world standard. We then try to analyze this situation semi-quantitatively in the light of logistic function analysis.

Scientific paper contribution 2: The Ultimate Dilemma For Artificial Capitals: ever scarcer natural resources claim ever larger artificial capital
This paper is co-authored by Nobuo Kawamiya.

Abstract: The theory of “Weak Sustainability” has long presupposed a favorable substitutability of artificial capitals for natural resources. All the growth-oriented economists favored this paradigm and used to conceive various optimistic growth paths. However, prolonged lavish consumption of fossil fuels has recently brought forth deterioration of reserve quality and of remarked degradation of ERoEI (Energy Return on Energy Investment), which reciprocally implies ever larger artificial capital to be claimed for extraction. The latter, instead of substituting the former (natural resources), must now be consumed in an ever increasing amount just for extracting the primary energy.
