“Pay has little to do with motivation in the workplace”.That’s the argument put forward by best-selling author Daniel Pink in his new book, Drive: The Surprising Truth About What Motivates Us.“Pay for performance is supposed to be a folk tale,” he says.

Daniel argues that, if employees receive a basic level of payment, three other factors matter more than money: a sense of independence, of mastery over one’s labor, and of serving a purpose larger than oneself.For example, in 2008 at the offices of Best Buy’s Richfield, salaried workers there were allowed to organize their own work day, putting in only as many hours as they felt necessary to get their jobs done.Productivity increased by 35% according to The Harvard Business Review.

But the managers at Goldman Sachs aren’t exactly making some efforts to adjust.Like others on Wall Street, the banking giant argues that fat bonuses (extra rewards) are essential to make its numbers.“That’s exactly the attitude that leads to the recent financial crisis in the United States,” responds Daniel, “as managers always focus on short-term rewards that encourage cheating, shortcuts, and dishonest behavior.”

Moreover, the 45-year-old author and former Al Gore speechwriter refers to social-science experiments and experiences at such workplaces as Google and 3M.In one 2005 experiment he describes, economists working for the Federal Reserve Bank of Boston tested the power of incentives (激励) by offering cash rewards to those who did well in games that included reciting a series of numbers and throwing tennis balls at a target.The researchers’ finding: Over and over, higher incentives led to worse performance --- and those given the highest incentives did the poorest job.

From this and other cases, Daniel draws a conclusion that monetary incentives remove the element of play and creativity, transforming “an interesting task into a dull one.” It’s even possible, he adds, for oversized rewards to have dangerous side effects, like those of a drug dependency in which an addicted requires ever larger amounts.He refers to scientific testing that shows the promise of cash rewards increase a chemical in the brain similar to that brought on by cocaine or nicotine.

Daniel, however, is also aware that his company examples --- no GE, no IBM, no Microsoft --- hardly represent the commanding heights of the economy.But he thinks his approach will catch on, even in the biggest companies.“Managers tend to be realistic, and in time they will respond,” he says.

A.money is as addictive as cocaine or nicotine
