Table 11-5
A small island off the coast of Cape Cod contains two restaurants and two retail stores. Tourists
need to take a
ferry boat to reach the island, but with a recent slowdown in the economy, tourists
are less willing to pay for the
boat ride to visit the island. The owners of the restaurants and stores
on the island — Restaurants 1 and 2, and
Stores A and B — think that if tourists could ride the
ferry for free, they would be happy to visit the island, eat and
shop. The business owners are
considering contributing to a pool of money that will be used to pay for roundtrip
ferry service
each day. The table represents their willingness to pay, that is, the maximum amount that each
business owner is willing to contribute, per day, to pay for each ferry trip.
