Everyone we contacted in this matter was truly enthusiastic about the whole idea and vigorously supported it. It is quite common that a Festschrift is compiled by the students of the professor in question, and this is, to some extent, also true here. In one way or another, we are all Karl-Göran Mäler’s students. His contributions have in many ways served to define the shoulders of knowledge on which we stand when exploring our subjects further. Paul Samuelson once said that the only coin worth having was the appreciation of one’s peers. With Samuelson’s currency, Mäler is a very rich man, indeed, not only because the coins come, so to speak, from social scientists but also, for example, from natural scientists. Mäler’s work has been a mainstay of the frontiers of environmental economics for more than three decades, in both a stock and a flow sense. This is a remarkable achievement in itself. I certainly wish I knew the secret behind this, besides the usual formula: to work hard and to have exceptional powers. But I think we need more than this. Richard Feynman, one of the outstanding scientists of the last century, once said: ‘With more knowledge comes a deeper, more wonderful mystery, luring one on to penetrate deeper still. Never concerned that the answer may prove disappointing, with pleasure and confidence we turn...
