Types of Exchange Rates
- Fixed Exchange Rate: The value of a currency is pegged to another major currency (e.g., the US dollar) or a basket of currencies.
- Floating Exchange Rate: The value of the currency is determined by market forces without direct government or central bank intervention.
- Pegged Float: A hybrid where currencies are allowed to fluctuate within a range, but with some level of intervention.
Detailed Explanations
The nominal exchange rate is the price at which one currency can be exchanged for another. For instance, if 1 US dollar can be exchanged for 0.85 euros, then the nominal exchange rate is 0.85 EUR/USD.
Mathematical Models
The nominal exchange rate can be represented as:
$$ \text{Nominal Exchange Rate} = \frac{\text{Foreign Currency}}{\text{Domestic Currency}} $$
