According to Stiglitz, last week's poor U.S. jobs figures underscore such concerns.
The data showed that only 74,000 jobs were created in December, well below expectations of 200,000, creating uncertainty over the strength of the recovery, and leading some analysts to question whether Federal Reserve's decision last month to begin tapering its asset purchase program was premature.

"Let me say a word about that number - not only was it much less than expected, it's much less than the country needs," he said.
In addition to lower job creation, Stiglitz said a more worrying issue was the labor participation rate - the amount of people working and actively looking for work - which came in at 62.8 percent in December, its lowest level since 1978.
"We have millions who have given up looking for a job. They've looked and looked and there are no jobs...more and more Americans have said there's no future," he added.
Stiglitz also told CNBC that the Federal Reserve's massive quantitative easing program, which has seen over $3 trillion pumped into the economy since it began the process in 2008, has done little to help the domestic economy, and has been more of a global phenomenon.
"The effect in creating jobs in the U.S is very low. What we need is fiscal stimulus and that's what we're not getting," he said.

Last year, the much anticipated taper of the Fed's $85 billion a month asset purchase program transfixed investors for most of the year. The central bank finally moved last month, cutting purchases by $10 billion, but Stiglitz said the focus should be on the direction of interest rates, not tapering, which he described as "mild."
"They've [the Fed] said that they're going to keep interest rates at very low levels, close to zero, until the labor market improves...Given their focus on labor market, the likelihood that interest rates will rise in 2014 is very small," he added.
