The European Monetary Union (EMU) has been in place for three years, and researchers have analyzed its performance. They looked at how the Euro notes and coins were introduced, the challenges faced by the European Central Bank, and the impact of the common monetary policy on price stability and economic growth. The researchers also examined the credibility of the ECB, the reasons behind the weak Euro, and how national fiscal policies have responded to the monetary policy. They also explored how national inflation rates were affected by certain economic factors. Lastly, they discussed the potential issues related to the expansion of the EMU to include Eastern European countries.
