Since the 'environmental revolution' began in the late 1960s, economists
have done a lot of work in the field of economic theory-building on the
preservation of nature. Meanwhile, environmental economic literature has
swelled to a large stream of articles in journals of different
signature. As a result, a coherent economic view of the phenomenon
ofenvironmental degradation has emerged. Several kinds of 'green' public
policies and their impacts on both nature and the performance of the
economy have been analysed. The feasibility ofspecific types of policy
has also been discussed. The aim of the book is to provide an insight
into the ways economists analyse the problems ofenvironmental pollution
and the depletion ofnatural resource. To this purpose a number of
articles have been selected. Some of them have a fundamental character,
others an applied nature and are foremost, practically oriented. The
presentation of the collection emphasizes our belief that economists are
able to deliver an essential contribution to the design of policies to
protect nature. It is clear that 'nature' and 'environment' may no
longer be regarded as 'free gifts' to society. Rather, they have to be
seen as scarce resources, and environmental disruption and resource
depletion as allocation problems. Ifa natural resource is scarce, a
price must be charged in accordance with the degree ofscarcity since
otherwise society will be confronted with misallocations. In this
connection there are two topics which are of particular interest to
economists.
