Quote for the Week
The necessity to distinguish between the short run and the long run is one of the most difficult tasks the businessman faces — and yet perhaps it is the most essential of his tasks. At the same time, however, how does one determine whether the events of the past few weeks or months are just random blips or early harbingers of a more fundamental shift in the long-run environment? If short-run decisions made without regard to the long run are the sure road to disaster, we must also never forget that the long run is nothing more than an extended series of shorter-run variations. — Peter Bernstein (source)
