580 Chapter 13 The Value of Information- A distribution between $46 and $70 has noeffect on the optimal number
of buyers. The marginal benefit (MB) of contacting an extra buyer
depends on the dispersion of prices, and this is unchanged. For a
distribution between $46 and $58, the standard deviation is half as great
as originally, and so is marginal benefit. The optimal number of buyers is
either two or three (a tie). The MB of adding a third buyer is $1 million,
identical to MC.
