An important class of externalities to which attention has recently been directed is called information externalities. The information produced by one individual or firm generates benefits for others. The success of an oil well on one tract of land increases the likelihood of oil's being found on an adjacent tract, and hence increases the value of that tract. Can you think of other examples of information externalities? What are the likely consequences of information externalities for the effi ciency of resource allocations? Discuss the possibilities of private market solutions to these problems.
