Question 895 comparative advantage in trade, production possibilities curve
Adam and Bella are the only people on a remote island.
Luckily there are Coconut and Date palm trees on the island that grow delicious fruit. The problem is that harvesting the fruit takes a lot of work.
Adam can pick 7 coconuts per hour, 6 dates per hour or any linear combination of coconuts and dates. For example, he could pick 3.5 coconuts and 3 dates per hour.
Bella can pick 3 coconuts per hour, 5 dates per hour or any linear combination. For example, she could pick 1.5 coconuts and 2.5 dates per hour.
This information is summarised in the table and graph:

Question 981 margin loan, Basel accord, credit conversion factor
Margin loans secured by listed stock have a Basel III risk weight of 20%.
For margin loans that cannot be immediately cancelled by banks and asked to be repaid, the credit conversion factor (CCF) is 20%.
Suppose you have a stock portfolio worth $500,000, financed by:
- $300,000 of your own money; and
- $200,000 of the bank’s funds in the form of a margin loan which can only be cancelled by the bank after 5 days notice. The margin loan’s maximum LVR is 70%.
How much regulatory capital must the bank hold due to your margin loan? Assume that the bank wishes to pay dividends to its shareholders, so include the 2.5% capital conservation buffer in your calculations.
