Simply put, Weitzman integrates the economics of fishing and forestry and Plummer integrates the economics of fishing and mining The final section of this volume relates to Gardner’s abiding interest in non-market valuation Gardner’s work in this area began in the 1960s and continues today In his research, Gardner has been at the forefront of applying techniques ranging from open-ended Contingent Valuation...Foreword We thank the University of Washington Department of Economics for sponsoring ‘Frontiers in Natural ResourceandEnvironmentalEconomics , a conference in honor of Gardner M Brown, Jr., that led to this book In particular, we thank Richard Parks for his efforts in planning a wonderful event and helping to lay the foundation for this book; Neil Bruce, who supported and encouraged us to plan a conference... dispersal) plays in generating net benefits in the sink, and net costs in the source Ceteris paribus, optimal management of a sink/source system calls for relatively more biomass in the sink and less in the source, capitalizing on the natural direction of the flow of dispersal Changing economic parameters modifies this basic tendency, in a manner that depends upon whether biological and economic gradients... neoclassical Random Utility model xiv Introduction We anticipate that the reader will find in these 12 chapters what we see in the more than 40 years of Gardner M Brown, Jr’s career: a willingness to engage important environmental andnaturalresource problems using the instrument of economics, and a commitment to developing economic models up to the task of addressing important environmental problems Together...
