In the real world it is the producer who most often takes on the role of perceiving and making changes, motivated by profit opportunities. Many of the opportunities for more efficient use of resources simply go unnoticed by non-producers because only those who are involved in the production process actually encounter them or understand them. Often these opportunities are the result of imperfect coordination between transactions in the resource markets and in the product markets. By involvement in the market process profit seekers create the possibility of greater cooperation between otherwise disconnected segments of the economy.
