2. Consider Farmer Grover who grows corn Ｃ , which can be sold at a price

   of Ｐc per bushel. The number of bushels he grows is a function of the

   amount of time the farmer chooses to spend growing corn Ｎ , i.e.

   Ｃ＝Ｆ（Ｎ）. The marginal product of labor in corn production is

   positive but decreasing. The farmer also earns ter income of Ｙ. The

   farmer receives utility from consuming Ｚ , which he purchases at a

   price of Ｐz per unit and from leisure Ｌ . He has a time endowment

   of Ｔ hours and therefore Ｌ＝Ｔ－Ｎ .

   (A) If the farmer's utility function in Ｕ（Ｌ,Ｚ）, the what will be

       his utility maximization problem ？

   (B) What are the first order and second order conditions in this

       problem ？

   (C) Suppose the quantity of time the farmer chooses to spend growing

       corn is independent of Ｙ . Show that Ｎ will rise when Ｐc rises

       and present an intutive explanation of this result.
