SIMILARITIES BETWEEN HOME TRADE AND FOREIGN TRADE:
SIMILARITIES BETWEEN HOME TRADE AND FOREIGN TRADE:
Objective: Businessmen involved in
home trade and foreign trade buy and sell goods for the same objective.
That is to make a profit. Dependence:
Both, home trade and foreign trade depend very much on aids to trade. That
is there is much dependence on transport, insurance, finance, warehousing,
etc, Specialization:
Both, home trade and foreign trade depend very much on specialization,
whether it is national, regional or personal.
