In his baccalaureate address at Princeton this year, the Fed chairman Ben Bernanke defined economics as “a highly sophisticated field of thought that is superb at explaining to policymakers precisely why the choices they made in the past were wrong.” He added, “About the future, not so much.” Put another way, economics is a science that can mean what economists want it to mean. As W.C. Fields replied when asked whether poker was a game of chance: “Not the way I play it.”
Now comes the hard part. Fed Chairman Ben Bernanke’s announcement that if the conditions are right he will wean the U.S. economy off quantitative easing within a year has already caused consternation in the stock market. Pumping money into the system by buying back government bonds at the rate of $85 billion a month has lately done little good, which is a persuasive reason to wind it down. But getting from here to there without incident is not going to be easy. It was simpler for Howard Hughes to land his gargantuan super-plane, the Spruce Goose.
There is nothing more likely to spark anger than an unfair tax regime. The American Revolution was founded on it. So the discovery that some of the largest and most successful companies in the world — among them Google, Apple, Amazon and Starbucks — have legally minimized the tax they pay, sometimes to as low as zero, in many nations in which they earn the lion’s share of their revenue is causing considerable irritation.
Robert Fogel, who died this week, won a Nobel for economics by mining historical data and in the process shook up the study of history forever. Just as with cholesterol, it seems there is good data mining and bad data mining. Fogel’s was undoubtedly the good kind.
Whatever high crimes and misdemeanors the National Security Agency leaker Edward Snowden may or may not have perpetrated, he has at least in one regard done us all a favor. He has reminded us that we are all victims of unwarranted and inexcusable invasions of privacy by companies who collect our data as they do business with us.
