ECO – Pai lives alone on a deserted island ECO – Pai lives alone on a deserted island Question Pai lives alone on a deserted island. He can spend his time gathering coconuts orbananas. He has 16 hours available each day and can gather 4 coconuts in an hour or8 bananas in an hour.Show the derivation process that leads to the final solution for all parts of question. a) Given that Pai's marginal utility of bananas is always 25 and his marginal utilityof coconuts is always 100, what is his optimal consumption? Draw his budgetconstraint and indifference curve and identify his optimal bundle in a diagram.(15 marks)b) One day an individual from a neighbouring island arrives by boat and offers toexchange any number of fruits at a rate of 1 coconut for 1 banana. Plot Pai'sbudget constraint at this exchange rate assuming he will now spend all her timegathering bananas. Is Pai better off? What is his new optimal consumption? Showthe results in the diagram.
