Growth in advanced economies should "strengthen gradually" from the middle of this year through to 2014

The global recovery is emerging, but it has two speeds: That of the stimulus-fed U.S. and that of the austerity-starved eurozone, according to a new report.

However, the upturn “continues to diverge across countries, with the U.S. likely to grow faster than other large OECD economies.”

Euro area growth, the report continued, “remains constrained by the lingering effects of the euro area crisis, the ongoing drag from fiscal consolidation and weaknesses in credit markets.”

The OECD used the outlook to call for bolder measures solve the crisis and faster movement toward a full-fledged banking union.

The report found labor markets would firm in the U.S. and Japan but unemployment would continue to rise in the euro area through 2014.

The report warned: “Structural reforms are essential to prevent cyclical unemployment from becoming structural.”

The OECD said U.S. annual GDP growth will be 2.8% in 2014, up from 1.9% in 2013. The euro area will contract by 0.6% in 2013 before growing by 1.1% in 2014.

In total, the OECD countries will have GDP growth of 1.2% in 2013 rising to 2.3% in 2014.

Euro area unemployment is predicted to peak at 12.3% in 2014, from 12.1% in 2013.
