When the person works for 8 hours the PPC takes on a particular shape. Assuming that the number of coconuts the person can collect or the number of fish he can catch is proportional to the time spent in doing the same there is an increase both in both the quantities. For instance in 12 hours the person can collect 36 coconuts or catch 0 fish; collect 30 coconuts or catch 1.5 fish...
As there is a change in the number of both the quantities in all cases the shape of the PPC does not change. It only grows larger in size. Whether the person were to work for 8 hours or for 12 hours in either collecting coconuts or catching fish the relative decrease in the production of the other remains the same.
