Q

What should the CB do if there is a fall in the demand for the currency? (fixed-exchange?)

A

Fall in demand for GBP
–> Surplus/ excess supply of domestic currency is the resulting problem
–> the central bank buys the surplus, shifting D2 back to D1 –> keeping exchange rate fixed

Q

How would “increase in interest rates” maintain a fixed exchange rate?

A

The central bank can increase interest rates, which attract financial investments from other countries.
This leads to a higher demand for the domestic currency, shifting the demand for currency.

Q

How would “borrowing from abroad” maintain a fixed exchange rate?

A

If the country borrows from abroad, its loans will come in the form of foreign exchange, which when converted into boples will cause an increase in the demand for bples and hence a rightward shift in the demand curve.

Q

How would “efforts to limit imports” maintain a fixed exchange rate?

A

The government could use policies to limit imports, because this reduces the supply of the domestic currency (since it reduces demand for foreign exchange needed to buy imports), causing a leftward shift in the currency.

Q

What is a “Managed-Floating” exchange rate?

A

In between the two extremes of floating exchange rates and fixed exchange rates.

Exchange rates are for the most part free to float to their market levels over long periods of time; however, central banks periodically intervene to stabilise them over the short run.
