Business Week had a cover story last week by Peter Coy “What Good are Economists Anyway?” In it he suggests that economists did not see the recession coming, and that macroeconomists cannot even know whether or not the current fiscal policies being undertaken will work. He writes “To be fair, economists can’t be expected to predict the future with any kind of exactitude. The world is simply too complicated for that. But collectively, they should be able to warn of dangers ahead. And when disaster strikes, they ought to know what to do. Indeed, people pay attention to economists at times like this precisely because of their bold claim that they know how to prevent the economy from sliding into a repeat of the Great Depression. But seven decades after the Depression, economists still haven’t reached consensus on its lessons. The debate has only intensified in recent weeks.”
First, is it the economist’s role to predict these types of downturns? To my knowledge that is not the definition of economics. Second, many economists did see this coming and warned about it, but these are not the economists that CNN, Fox News, and other media outlets interview. Mostly because they will not provide the kind of certainty or precision that media outlets often desire. There is a macroeconomics debate here, but it is not new and despite what Peter Coy implies it never really went away. One has to realize that economists are not policy makers, and while they may advocate one policy or another it is the politicians in charge at any moment that implements the policy. Is it possible that some economists who were weary of the economic situation were ignored by policy makers?
A final thought, a colleague Ed Lopez recently brought to my attention this quote by economist G. L. S. Shackle on what it means to be a complete economist. It is very interesting and a lot to live up to. I think the best any us can hope for is to be a real economist. It seems an interesting juxtaposition to the Business Week article.
“To be a complete economist, a man need only be a mathematician, a philosopher, a psychologist, an anthropologist, a historian, a geographer, and a student of politics; a master of prose exposition; and a man of the world with experience of practical business and finance, an understanding of the problems of administration, and a good knowledge of four or five languages. All this in addition, of course, to familiarity with the economic literature itself.”

The potential real economist is “…the outstanding intellectual all-rounder with some leaning towards the arts rather than the natural science side. The person who finds mathematics fascinating without, perhaps, marching through the school course with that instinctive and professional certainty that would mark him as an out-and-out mathematician; who betrays a connoisseurship of words and a delight in language, a gift for expression in English and a sufficient pleasure in the classical languages to awaken thoughts of scholarships, without really promising to become a Porson’s prizeman; who can find in every chapter of the history book the universal and eternal problems of man’s dependence on his fellow-men side by side with his rivalry and conflict with them, and can see with the historian’s eye the age-long empirical struggle to reconcile self-interest and enlightened compassion; who delights in maps and finds them, perhaps, more interesting than test tubes…. [T]his is the potential real economist.”
