The mixed picture comes amid concerns about the strength of the euro zone's economic recovery. After the longest contraction in continental Europe in over 40 years, the region pulled out of an 18-month stretch of negative growth in the second quarter of 2013.
But data published earlier this month revealed that the euro zone's economic growth slowed in the third quarter. Gross domestic product (GDP) for the 17-nation bloc came in at just 0.1 percent quarter-on-quarter in the third quarter, marking a slowdown from a 0.3 percent expansion in the second quarter.
Meanwhile, last week, the composite purchasing manager's index (PMI) survey for the region revealed that business activity in the euro zone fell unexpectedly in November, prompting concerns that the region's recovery was losing steam.

Howard Archer, chief U.K. and European economist at IGS Global Insight, said Thursday's business and consumer survey supported hopes that the euro zone could gradually establish economic recovery - despite the relapse in GDP growth.
"Looking ahead, the hope for the euro zone is that current rising confidence will encourage businesses to lift their employment and investment plans," he said in a note.
"However, November's dip in consumer confidence reinforces suspicion that euro zone consumers will likely remain generally pretty cautious in their spending in the near term at least which will hardly help growth prospects."
Economic sentiment improved in four of the five largest euro zone economies - Italy, Spain, the Netherlands and Germany - but deteriorated in France, in yet another sign that the country's economy was being left behind.

The survey came on the same day that separate data, published by the European Central Bank (ECB), reveal that lending to businesses in the euro zone disappointed in October.
Lending to euro zone businesses fell by 14 billion euros in October - after slipping by 11 billion euros in September.
"Banks likely believe the economic situation and outlook in many euro zone countries still provides an uncertain and risky backdrop in which to lend despite the euro zone eking out modest growth since the second quarter," Archer added.
