Shomu Banerjee ECON 201 GAME THEORY QUIZ Tom is a monopoly manufacturer who can use laborers to pack his product into boxes or use an expensive set of robotic arms which will reduce the number of workers he hires but increase his fixed cost. Tom’s profit is $900 without the machine and $500 if he buys the machine. Ann is an entrepreneur and is wondering if she should enter this market (which would turn it from a monopoly into a duopoly). If she does not enter, she earns $0. If she does enter, Tom earns $400 if he uses labor and $132 with the robot, while Ann earns $300 when Tom uses labor and makes a loss of $36 if Tom buys the robotic arms.
