Abstract

I scratch your back, you scratch mine—how must these services relate in order to constitute a quid pro quo exchange? In the ordinary quid pro quo exchange, each party agrees to do their part in order to get the other party to do theirs; each conditions their own willingness to perform on the willingness of the other; and each regards the other as obligated to do their part in light of their agreement. But not all exchanges are ordinary, and a proper analysis is of considerable practical and theoretical significance. In the law alone, quid pro quo figures prominently in a wide range of contexts—civil as well as criminal, public as well as private—and lies at the core of a number of raging controversies concerning official corruption, insider trading, and other matters. This Article offers the first philosophical analysis of quid pro quo exchange in the Anglophone tradition.
