Suppose the spot price of wheat (a pure consumption commodity) is $3.65 per bushel. Storage costs are $0.80 per bushel per year payable quarterly in advance, i.e., $0.20 now for the first three months, $0.20 in three months for the next three months, etc. The interest rate is 6 percent per year with continuous compounding. Suppose the actual quoted price for a six-month forward contract is $4.00 per bushel. What is the implied convenience yield, y, of the wheat?
