Curator: If our museum lends Venus to the Hart Institute for their show this spring, they will lend us their Rembrandt etchings for our print exhibition next fall  Having those etchings will increase attendance to the exhibition and hence increase revenue from our general admission fee  Museum Administrator: But Venus is our biggest attraction  Moreover the Hart's show will run for twice as long as our exhibition
So on balance the number of patrons may decrease
whether getting the Rembrandt etchings from the Hart Institute is likely to increase attendance at the print exhibition
