In 2006 the French bank Crédit Agricole bought the Greek Emporiki bank, for €2.8 billion, at the peak of a bull market for bank takeovers. Six years, a major financial crisis, and 5.2 billion of losses later, in a context of great uncertainty in the European banking sector, what decision should Crédit Agricole take regarding Emporiki? Through the example of this European cross-border acquisition the case looks at the Greek banking system before and during the unprecedented Greek sovereign debt crisis; the efforts of Greece and the main actors of the European financial system to prevent the battled country from having to exit the euro zone; and the potential scenarios for Greek banks in mid-2012.

The sovereign debt crisis that took Greece by storm in 2010 began to spread to other European markets. Within a few months Ireland and Portugal had also lost access to the sovereign debt markets and had to rely on supranational loans for their financing. The risk of further contagion was clear and present. Political leaders continued to seek measures to stem the crisis and to avoid the larger economies of Spain and Italy becoming involved. The European financial system became strained. Banks were found to be undercapitalized and began to ration credit to the economy. The European Central Bank intervened to provide liquidity to the system in order to avoid a credit crunch. Could the eurozone survive the storm?

This note discusses the economics of government-debt accumulation. Fiscal deficits are only part of the picture; other factors include the level of debt as a percent of nominal GDP; the interest rate; the inflation rate; the growth rate; and changes in the exchange rate if some debt is owed in a foreign currency. The note discusses how these factors interact to affect government debt levels.

After its 2009-2010 fiscal crisis shook the euro, could the Greek government stabilize debt, avoid default, and stay on the euro? This case looks at the Greek social and political road to fiscal crisis; the economics of that crisis and efforts to recover from it; the danger the crisis posed to the euro; cooperation and conflict among European states, the European Central Bank, and the International Monetary Fund to try to help Greece emerge from crisis; and the role financial markets played in these events.

This case traces the origins and evolution of the European Central Bank, with attention to its 2010 decision concerning the purchase of Greek sovereign debt.

In 2009, Chile's Finance Minister Andres Velasco's fortunes had been reversed. His fiscal policy that had come under attack just a year ago had been used to finance a $4 billion fiscal stimulus package amid the global economic downturn. Velasco was now Chile's most popular minister. However, the future of Chile's fiscal policy was questionable with the election of a new president, Sebastian Pinera, the first conservative leader to lead Chile in two decades.

In 2008, Andres Velasco, Chile's Finance Minister, was under mounting criticisms over his fiscal policy. As the world's largest copper producer, Chile was benefiting from the rise in copper prices, which had more than tripled since 2003. Copper revenues translated into greater income for the government as Chile's biggest copper producer, Codelco, was a state-owned enterprise. Velasco had chosen to save the bulk of the copper revenues into two stabilization funds; by the end of August 2008, the collective amount represented more than 20% of Chile's GDP. Several critics wanted the funds to be used to improve the poor public education system, income gap, and other impending social issues. After all, Chile had one of the most unequal distributions of wealth in the world. Productivity was stagnant and economic growth had slowed down significantly since the 1990's. What should Velasco do amid growing public discontent? Was it really in Chile's best interest to keep saving the copper wealth?

This case describes the efforts of Ben Bernanke, Chairman of the Federal Reserve, to improve liquidity in money markets during the subprime crisis.
