Introduction
Dollarization is a significant economic strategy employed by countries to stabilize their economies. It involves the adoption of the US dollar as either a sole or parallel currency to mitigate issues such as high inflation and volatile interest rates.
Historical Context
The phenomenon of dollarization dates back to periods of economic instability where countries faced rampant inflation and needed a stable currency to restore confidence. Notable instances include:
- Ecuador (2000): Ecuador fully adopted the US dollar after a severe economic crisis in the late 1990s.
- Zimbabwe (2009): Following hyperinflation, Zimbabwe allowed the use of multiple foreign currencies, including the US dollar.
- Panama (1904): One of the earliest adopters, Panama has used the US dollar alongside the Balboa since its independence.
Types of Dollarization
- Full Dollarization: The complete replacement of a country’s national currency with the US dollar.
- Partial Dollarization: The US dollar is used alongside the national currency. This can take two forms:
- Official: The government sanctions the use of the US dollar.
- Unofficial (De Facto): The US dollar is widely used by citizens and businesses even without formal government approval.
- Pegged Exchange Rate: The national currency is pegged to the US dollar, often at a 1:1 ratio.
Key Events
- 2000 Ecuador Dollarization: Facing hyperinflation, Ecuador transitioned to the US dollar to stabilize its economy.
- 1991 Argentina: Adopted a currency board system pegging the peso to the US dollar to fight inflation (eventually abandoned in 2002).
Detailed Explanations
Mathematical Models/Formulas
Exchange Rate Pegging Formula:
$$ E_t = \left( \frac{P_t^d}{P_t^f} \right) $$where \( E_t \) is the exchange rate, \( P_t^d \) is the domestic price level, and \( P_t^f \) is the foreign price level (US dollar).
