For policy, the central fact is that Keynesian policy recommendations have no sounder basis, in a scientific sense, than recommendations of non-Keyne… - Robert Lucas

The main development I want to discuss has already occurred: Keynesian economics is dead [maybe ‘disappeared’ is a better term]. I don’t know exactly when this happened but it is true today and it wasn’t true two years ago. This is a sociological not an economic observation, so the evidence for it is sociological. For example, you cannot find a good, under 40 economist who identifies himself and his work as ‘Keynesian’. Indeed, people even take offense if referred to in this way. At research seminars, people don’t take Keynesian theorizing seriously any more—the audience starts to whisper and giggle to one another. Leading journals aren’t getting Keynesian papers submitted any more.

The Keynesian Revolution was, in the form in which it succeeded in the United States, a revolution in method. This was not Keynes’s intent, nor is it the view of all of his most eminent followers. Yet if one does not view the revolution in this way, it is impossible to account for some of its most important features.

I do not see how one can look at figures like these without seeing them representing possibilities. Is there some action a government of India could take that would lead the Indian economy to grow like Indonesia's or Egypt's? If so, what exactly? If not, what is it about the "nature of India" that makes it so? The consequences for human welfare involved in questions like these are simply staggering: once one starts to think about them, it is hard to think about anything else.
