A Problem Facing the Timber Industry Is the Absence of Any

A problem facing the timber industry is the absence of any effective way to prove that rain forest timber was legally logged from places like Indonesia,where as much as 80 percent is the product of illegal logging.Companies like The Home Depot do not want to sell timber from illegally logged forests even though the demand is great for timber from rain forests.Exchanges between Home Depot and companies that are selling illegally-logged timber will not occur because:

A) there are more than two parties involved
B) each party has something of value to bring to the exchange
C) one party is free to accept the exchange offer
D) each party believes it is appropriate to deal with the other party
E) nobody sees the exchange as producing value
