This paper applies the Directed Technical Change (DTC) framework to study improvements in the efficiency of energy use. We present a theoretical model which (1) shows that the demand for energy is shifted down by innovations in energy intensive sectors and (2) highlights the drivers of...

Both technological and natural resource possibilities seem to evolve in cycles. The “Resource Opportunity Model” in this paper introduces the technological opportunity thinking into natural resource modeling. The natural resource industries’ choice between incremental, complementary...

In this article we show how absolute poverty and per capita growth can be sustained simultaneously in a fully integrated world economy even in the absence of population growth. In contrast to the literature we use a model of endogenously sustained growth in which not only the intensity of...
