This paper aims to discuss environmental risk management from a new
perspective. Although there is a growing literature dealing with the relation between
the economy and the environment in the absence of risk and uncertainty, it is quite
unfortunate that the effects of a variety of risk factors on such a relation have not been
intensively investigated by social scientists.
Before 11 March 2011, most people believed in the myth of absolute safety. Since
the Great East Japan Earthquake took place, however, their concept of risk for nuclear
power generation has been changed completely. What they once regarded as the
unthinkable events is no longer beyond imagination. This clearly indicates the
necessity of studying environmental risk management in a new perspective.
In this paper, we would like to show that simple applications of the conventional
expected utility theory would possibly lead us to wrong conclusions. It is high time for
us to combine both economic and non-economic (cultural and psychological) factors
towards a more synthetic theory of decision making under risk and uncertainty.
