Answer the folowing question

Make a model in which (i) people use government-supplied policing, G, and private security spending as substitutes for crime fighting, and (ii) if W is a person's total yearly requirement of money, he can choose to keep only a fraction of this W with him. This will entail n = 1/ trips to the bank. Assume each trip to the bank gives him a constant disutility of d. After setting up the model, can you say something about the conditions under which a rise in G (i) reduces private security spending, and (ii) reduces ? (10 marks)
