John Vasil Krutilla (February 13, 1922 – June 27, 2003) was an American environmental economist, known for inventing the concept of existence value, the idea that undisturbed wilderness has economic value ("nonuse value").[1][2] According to Kenneth Arrow,
"John Krutilla can fairly be said to have created or stimulated most of the agenda of modern environmental economics. . . . He pioneered in developing the idea later called 'existence value,' the value generated by the mere existence of an amenity, such as an unspoiled wilderness or species of animal or plants."[3]
