Research Gate: David Hadley

I am applied economist with research and teaching interests in the areas of environmental and agricultural economics. I’m particularly interested in non-market valuation methodologies and incorporating those values into approaches to decision-making, predominantly benefit-cost analysis. I also do applied work which measures efficiency and productivity of different types of farm enterprises. I am British and have been in Australia since 2010, prior to coming here I worked at the University of East Anglia as a researcher and I have also worked in public service with Ofwat (The Water Services Regulation Authority). In the dim and distant past I have also erected steel buildings, spent far too long as an accounts clerk for various insurance and reinsurance companies and had a brief and unsuccessful part-time career as a musician.


Bsc (Hons) Agricultural Economics, University of Reading, 1993 and PhD University of Reading, 1997.

Post-graduate Level

ECON526 Benefit-cost Analysis

ECON429 Environmental and Natural Resource Economics

Research Interests

My principal research areas are concerned with the valuation of ecosystem goods and services and economic assessment methodologies that incorporate these valuations (predominately cost-benefit analysis). My focus has been on 'wet' ecosystems; wetlands, river water quality and marine and coastal environments. I also have a further strand of research based in efficiency and productivity analysis; particularly with respect to agricultural production, and with the incorporation of environmental externalities into measures of productivity. I am also involved in several projects that measure efficiency and productivity in more conventional ways. More recent research has been concerned with the efficiency of agricultural production in africa and the adoption of new techniques by smallholder African farmers.
