Future hiring will mainly benefit the high-skilled

— NEW INDUSTRIES: Deepak Advani, an IBM executive, has a title he says didn’t exist five years ago: “Vice president of predictive analytics.”

Companies and government agencies have amassed data on behavior ranging from shopping habits to criminal activity. Predictive analytics is the art of determining what to do with that data. How should workers’ time be deployed? How best to target customers? Such jobs could grow 20 percent by 2018, the government predicts.

Still, economists say more will be needed to boost job growth. The answer may be some technological breakthrough akin to the personal computer or the Internet.

“Most big booms come from a particular sector that moves the rest of the economy,” said Richard Freeman, a Harvard labor economist.

Technology spurred job growth after the 1982 and 1991 recessions. The PC became revolutionary in the early 1980s. Internet use exploded after the Mosaic Web browser was introduced in 1994. Housing eventually lifted employment after the 2001 dot-com bust.

“There’s a lack of clarity on what the next big thing is going to be this time,” said David Card, an economics professor at the University of California.

Until there is, many people will have to lower expectations and living standards as they enter fields with less pay and less job stability, said Dan Finnigan, CEO of online employment service Jobvite.

“People who are unemployed have to embrace this future that they are going to have many jobs,” he said. “We will always be working on the next gig.”
