Suppose that Robinson Crusoe produces and consumes fish (F) and coconuts (C). Assume that, during a certain period, he has decided to work 200 hours and is indifferent as to whether he spends this time fishing or gathering coconuts. Robinson's production for fish is given by
width=
a. If Robinson cannot trade with the rest of the world, how will he choose to allocate his labor?
What will the optimal levels of F and C be? What will his utility be? What will be the RPT (of fish for coconuts)?
b. Suppose now that trade is opened and Robinson can trade fish and coconuts at a price ratio of pF/pC= 2=1. If Robinson continues to produce the quantities of F and C from part (a), what will he choose to consume once given the opportunity to trade? What will his new level of utility be?
c. How would your answer to part (b) change if Robinson adjusts his production to take advantage of the world prices?
d. Graph your results for parts (a), (b), and (c).
