Two equal-sized newspapers have overlay circulation of 10% and 10% of the subscribers subscribe to both newspapers. Advertisers are eager to pay $10 to advertise in one newspaper but only $19 to advertise in both, for the reason that they're unwilling to pay twice to reach the same subscriber.

Presume the two newspapers merge. What is the probable outcome?
