Why would a nation dollarize—that is, adopt another country’s currency instead of having its own?

Can you think of any major disadvantages of dollarization? How would a central bank work in a country that has dollarized?

If a country’s currency is expected to appreciate in value, what would you think will be the impact of expected exchange rates on yields, for example, the interest rate paid on government bonds, in that country?

Do you think that a country experiencing hyperinflation is more or less likely to have an exchange rate equal to its purchasing power parity value when compared to a country with a low inflation rate?

Suppose a country has an overall balance of trade so that exports of goods and services equal imports of goods and services. Does that imply that the country has balanced trade with each of its trading partners?

What would make a country decide to change from a common currency, like the euro, back to its own currency?
