a.假设该经济拥有的总资源量为：600小时的劳动和60英亩的土地。请画图说明资源应如何分配。
b.现在假设劳动供给分别上升到800小时、1000小时、1200小时。请用一幅如(本书中)图4-6的图展示出资源分配变化的轨迹。
c.如果劳动供给继续增加将出现什么样的情形？
Suppose that at current factor prices cloth is produced using 20 hours of labor for each acre of land， and food is produced using only5 hours of labor per acre of land.
a. Suppose that the economy' s total resources are 600 hours of labor and 60 acres of land. Using a diagram determine the allocation of resources.
b. Now suppose that the labor supply increases first to 800， then 1000， then 1200 hours. Using a diagram like Figure 4-6， trace out the changing allocation of resources.
c. What would happen if the labor supply were to increase even further？
