This chapter explains that signaling refers to an action that an individual with private information takes in order to convince others about his information. Screening also involves private information, but is somewhat different from signaling. Screening refers to an action taken by an uninformed person to learn about someone else’s private information. So, for example, you are engaged in screening if you have a mechanic inspect a used car you are considering buying.
The biblical story of King Solomon is in 1 Kings 3:16-28 (en.wikipedia.org/wiki/Judgment_of_Solomon). Two young women who both had an infant son came to Solomon for a judgment. One of the women claimed that the other, after accidentally smothering her own son while sleeping, had exchanged the two children to make it appear that the living child was hers. The other woman denied this and so both women claimed to be the mother of the living son and said that the dead boy belonged to the other. Show that King Solomon understood screening very well.
