8. Crusoe can grow 100 bushels of grain each year. Draw his budget constraint for this year and next year if:
a) he is alone on an island. He can store grain but 10% of it will rot from the first year to the second. (Hint: the axes are consumption in year one and consumption in year two.)b) he is living in a primitive barter economy. The only way to store his grain is in the local warehouse, which charges him 10% of what he has to store. However, nothing spoils. He can also borrow against next year's crop, but at a 20% interest rate (payable in grain.)
