|Two individuals, Alexander and Vanessa, benefit from scientific research. Alexander’s marginal private benefit from such research is given by the equation P = 200 – Q, where Q refers to the amount of research undertaken and P is the price Alexander is willing to pay for such research. Vanessa’s marginal private benefit from such research is given by the equation P = 100 – Q. Suppose the marginal social cost of engaging in such research is constant at $100.
