Thermodynamics on Main Street: When entropy really counts in economics

The implications of thermodynamics for economic theory have been a source of debate for 40 years. Adopting the framing used in modern engineering rather than physics suggests that the market place has already recognised most of these thermodynamic truths as self-evident rather than challenging basic concepts. The exception is the relatively small market for heat where the idea of thermodynamic grade, conveniently represented by the exergy or available work content of a heat source, exposes inconsistencies especially in monopoly supply and economic instruments. Earlier commentators were not wrong in the thrust of their criticisms of economic theory but may have been overly elaborate in their attack.     

The bumpy road of biomass gasification in the Netherlands: Explaining the rise and fall of an emerging innovation system

In this paper, the concept of System Functions of Innovation Systems is applied to provide an explanation of the success or failure of an emerging technology, i.e. biomass gasification, with empirical data on the evolution of this technology in the Netherlands during 1980-2004. A new list of System Functions has been developed lately and is used to identify the most relevant events in the evolution of the Biomass Gasification Innovation System. We show that a structural misalignment occurred between the institutional framework within which the technology could have been developed and the technical requirements of the technology. Finally, the absence of System Functions such as the guidance of the search, resource allocation and advocacy coalition explains the failure of this technology over time.
