10 households trading among themselves, 45 transactions would be necessary
to conduct decentralized exchanges at each production point (i.e., [10 × 9]/2).
But if the village added a central
market with one intermediary, it could reduce
the complexity of this exchange system and facilitate transactions, such that
only 20 transactions would be required to carry out the centralized exchange
(10 + 10).
Implicit in this example is the notion that a decentralized system of exchange is
less efficient than a centralized network that uses intermediaries. The same rationale
applies to direct selling from manufacturers to retailers,
relative to selling through
wholesalers. Consider Figure 2.1. Assuming four manufacturers and 10 retailers that
buy goods from each manufacturer, the number of contact lines amounts to 40. If
the manufacturers sold to these retailers through one wholesaler, the number of
necessary contacts would fall to 14.
The number of necessary contacts instead increases with more wholesalers. For
example, if the four manufacturers in Figure 2.1 used two wholesalers instead of
one, the number of contacts would rise from 14 to 28; with four wholesalers, the
number of contacts grows to 56. Thus, employing more and more intermediaries
creates diminishing returns, viewed solely from the
point of view of the number
and cost of contacts in the market. Of course, in this example we assume that each
retailer contacts each of the wholesalers used by manufacturers. But if a retailer
prefers a certain wholesaler, any effort by the manufacturer to restrict the number
of wholesalers creates the risk of excluding the retailer’s preferred wholesaler from
the channel, which could leave the manufacturer unable to reach the market served
by that retailer.
In this simplistic example, we also assume that the
cost and effectiveness of
each contact—manufacturer to wholesaler, wholesaler to retailer, manufacturer
to retailer—are equivalent. Such an assumption clearly does not hold in the real
world, where selling through one type of intermediary generally entails very dif-
ferent costs from those accrued by selling through another intermediary. Not all
intermediaries are equally skilled at selling or are motivated to sell a particular
manufacturer’s product offering, which certainly affects the choice of which and
how many intermediaries to use.
Thus we assert that it is the
judicious use of intermediaries that reduces the number
of contacts necessary to cover a market. This principle
guides many manufactur-
ers that seek to enter new markets but want to avoid high-cost direct distribution
through their own employed sales forces. The trend toward rationalizing supply
chains by reducing the number of suppliers also appears consistent with reducing
the number of contacts in the distribution channel.
In summary, intermediaries necessarily participate in marketing channels because
they both
add value and
help reduce costs. These roles raise another key question,
then: what types of work do the channels themselves actually perform?
