Explain. 2 Marks c) Now suppose that one can determine whether a partner is a “conditional co-operator” by paying an “inspection cost” of σ>0. A conditional co-operator is one who inspects and responds to a cooperative partner by cooperating and to a defector by defecting. We call these cooperative partner the “inspectors”. The only other type of strategy is unconditionally defecting. Hence the new playoff matrix becomes. Find the expected payoffs for Inspect and Defect strategies and the function that might give the interior equilibrium for the share of inspectors (α∗). 8 marks d) Assuming that 0
