ABSTRACT
The title of this lecture is intentionally sweeping, over-ambitious, and, I hope, provocative. Few, if any, individuals are qualified to provide an authoritative general survey and evaluation of late twentieth century economics 1 and I certainly am not one of them. The discipline is far too large, complex, fragmented, changing and, in many of its branches, sophisticated and technically difficult. Fortunately, however, one need not aim that high.
