This week, we look back on a few of the big economic stories of twenty eleven.
The debt crisis in Europe spread from it's started in greece and Ireland last year.
Portugal needed a financial rescue of over one hundred billion dollars in this spring. And Italian Prime Minister Silvio Berlusconi lost support because of his country's debt troubles. Former EU official Mario Monti took over as prime minister in November.
Greek debt continued to hurt European banks. Pressure on Europe's financial system from debt problems in countries using the euro have placed the future of the euro itself in debt. As a result, European finance officials have called for tighter financial cooperation and new rules.
But European leaders have yet to agree on enlarging the rescue fund meant for debt-troubled euro-area economies.
World Bank President Robert Zoellick say Europe will have to find answers to its debt problems.
ROBERT ZOELLICK: "Europe has to rescue Europe, OK? And it's very important. If there's any message when I'm asked, 'Well, what can the U.S. do and what can China do?' The best thing they can do is clean up their act at home, be a source of growth at home."
But Mister Zoellick also said it was important for other big economies to deal with their own budget imbalances.
ROBERT ZOELLICK: "The downgrade of America from triple A didn't affect the finances today, but it may be one of those events people look back on 10 years from now and say, 'Did they get the warning? '"
In August, the United States had its credit rating cut from the highest level, triple A, to double A plus. The move was widely blamed on the failure of American lawmakers to agree on details of budget cuts to reduce deficits.
In business news, the largest publicly traded technology company, Apple, lost its chief.
Steve Jobs brought the world the iPhone, iPod and iPad. He stepped down in August because of health problems. He helped make Apple into one of the world's most valuable companies. Steve Jobs died in October at the age of fifty-six.
Protests for political freedom swept North Africa and the Middle East in the Arab Spring. But protests over budget cuts and jobs were heard around the world.
In the United States, activists in hundreds of cities protested economic inequality and joblessness. Protestors were angry that banks got rescued with taxpayers' money during the financial crisis nearly four years ago. But many Americans continue to face hardship.
Anger over government budget cuts led to protests in Greece, Britain and elsewhere.
