Below is a report of the pros and cons of adopting a single currency between Australia and New Zealand.

Pros of Adopting a Single Currency:

1. Elimination of Currency Risk: By adopting a single currency, the two nations' commerce and investment would become more predictable and stable. This would eliminate the risk associated with currency fluctuations.
2. Increased Trade: Research indicates that nations that use the same currency often engage in more trade with one another. This has the potential to improve Australia's and New Zealand's economies.
3. Lower Transaction Costs: Businesses and consumers would have lower transaction costs if there was only one currency used, eliminating the need for currency exchange.
4. Greater Economic Integration: The two nations' economies may become more integrated as a result of a similar currency, which might spur economic expansion and prosperity.

Cons of Adopting a Single Currency:

1. Loss of Monetary Policy Independence: If two countries adopt a similar currency, they would be unable to independently determine their monetary policies, which could cause economic issues if they do not.
2. Potential for Economic Shocks: Because both countries use the same currency, an economic shock in one could potentially extend to the other.
3. Transition Costs: Changing to a new currency may be an expensive and disruptive procedure.
4. Potential for Widening Economic Divide: The adoption of a single currency may result in a wider economic divide between the two economies if they are not appropriately linked.

What are the likely gains from adopting a single currency for Australia and New Zealand? Do the gains outweigh the disadvantages for both countries that are likely to arise by giving up the right to conduct their monetary policy independently?
