Resource Management and Conservation
My work is primarily concerned with
management of resources and conservation. On the
technical side, I try to correct simple assumptions and
models that typically underestimate risks and foster
complacency about human impact. I am also grappling
with underlying attitudes and motivations that have
produced disastrous results in management of
resources. These are partially economic and social
issues, but I think that technical difficulties are also a
factor. This is especially true when substantial
uncertainties are present, but decisions must be made.
The economic literature on renewable and
non-renewable resources would benefit more from
attention to data, proper methods of inference and
dealing with uncertainty. A recent paper with Walters
and Hilborn led to an intense scientific discussion that
was noted in a feature NY Times article.
