The Times is reporting this morning that academic economists are considering an ethics code for the profession, something most other disciplines already have.
Naturally, there is opposition. Robert E. Lucas Jr. of the University of Chicago and winner of the Nobel Prize in economics is quoted as saying, “What disciplines economics, like any science, is whether your work can be replicated. It either stands up or it doesn’t. Your motivations and whatnot are secondary.” That, of course, is true up to a point. But economics is hardly the equivalent of, say, physics. Physics is a “hard science”; economics is squishy soft at best. Physics has only one basic theory; economics has many, often flatly at odds with each other. (I remember a doctor telling me once that “when there are a dozen treatments for a particular condition, you know that none of them are any damn good.”) And Lucas’s comment only applies to the academic literature, most of which is unintelligible to the man in the street (and not a few students taking Economics 101).
The real problem is that economics and politics are inextricably bound together. And politicians lie as often and as easily as they breathe. Indeed, the discipline was known as “political economy” in the 19th century. Economists often move between the academic and political realms, a professor one year, a chairman of the Council of Economic Advisors the next, and then back to academia. The council’s current chairman, Austan Goolsbee, is on leave from the University of Chicago. His predecessor, Christina Romer, was a professor at Berkeley before coming to the White House and is back there again. And they often have remunerative moonlighting gigs as well. Laura D’Andrea Tyson was chairman of the council in the Clinton years. She’s now a professor at Berkeley. She also sits on the board of Morgan Stanley, one of Wall Street’s biggest banks.
When an economist is writing a op-ed or being quoted in the popular media, as opposed to an academic paper, that’s at least as much politics as science. The various hats they wear should all be disclosed. That seems so simple that even an economist should be able to grasp it.
