DIFFERENCE
BETWEEN INTERNAL AND EXTERNAL TRADE
(1)Mobility
of factors of production ;Generally speaking ,as compared to the international
level of mobility ,factors internally are more freely mobile .in this case of
labor, mobility is rather difficult due to the existence of immigration laws
.for example the availability of work permits at international level is rather
difficult .in the case of capital ,although it is more easily mobile ,but
usually one would prefer to the invest in his own country ,inter alia .he feels
rather to do so likewise and moreover the Government generally encourages
people to invest internally rather than externally .land ,of course ,is
virtually immobile at international level and even at an internal level
.However ,generally speaking ,other obstacles which exist are e.g. culture
,language and other formalities .Moreover ,free mobility with in the country
leads to equality in the costs of production .
(2)Problem
of conversion of currency:
In
the case of internal trade such a problem does not arise because all
transactions take in the country’s own currency .problem arises at the
international where the currency of the every country has got to be converted
into US dollar (s),or sterling and However ,such a difference is not really
major obstacle in external trade .It is only a difference between internal and
external trade .
(3)Trade
restrictions:
These
are particular obstacles where external trade is concerned .This is as because
different countries will impose different policies in the form of import and
export duties and trade licensing .Moreover ,particulars countries may require
a commodity specially designed in the accordance with their needs e.g. in the
case auto mobiles ,cars etc ,have to meet standard required of the other
country for it to be able to be exported .
(4)TRANSPORT
COST:
The
cost or expenditures involved is the insuring that a commodity reaches one
place from the other varies interalia in
accordance with its trade level .Assuming that commodities are exported just
internally then its cost of the transportation will be much less as compared to
the similar cost involved at international level for the same commodity
(5)Government
concessions:
Generally
the govt provides special concessions to stimulate growth of the particular product internally
e.g. in the case of agricultural commodities ,electricity and loans are
provided at different rates of the respective entrepreneurs to encourage their
production and exports .This would reduce the cost of production favorable and
generally such facilities are not provided for external trade of the same
commodity unless the government wants to export it and that its demand
inelastic e.g. rice Malaysia.
(6)Government
policies:
For
the purpose of stimulating the growth of a product and stabilizing its price , the
govt applies various policies e.g. monetary policy ,fiscal policy ,agricultural
policy ,labour policy etc. This is usually done for international trade but may
be applied for internal trade as well .Now the nature of these policies are
different in different countries .That is why there is a difference in the cost
of production of different commodities .Thus ,as a result of the different
policies in different countries ,external trade is affected whereas internal
trade particularly remain stable .
(7)Application
of import and export policies :
Generally
speaking there is need for these commercial policies to be applied for internal
trade .However, for external trade these are a must and moreover ,must be done
keeping in the view of nature of resources available and the pattern of
exportables and importables between
countries . Such policies have got to be made every fiscal year to maximize
utilization of resources and climinate their wastage .
(8)Trade
situation:
The
trade situation at the international level changes rapidly , making it
practically difficult to predict a favourable condition for country and to
predict the desired demand and supply of the commodity at international level
.However ,at the domestic level ,the situation is somewhat better and less
elastic ,making it easier to conduct business.
THE
THEORY OF COMPARITIVE COSTS IN INTERNATIONAL TRADE
This theory was developed by Ricardo in 1817
.Basically, from the theory we are able to gather two main points i.e
(1)How
international trade takes place between countries? And
(2)How
it is beneficial to trade with the rest world?
As we have explained earlier ,
international trade takes place as a result of different costs of the
production of different products which in turn is based on either one or all of
the following I.e. climatic condition ,natural resources and technological know
how,
We
shall illustrate the theory here based in the following assumptions.
We
are only 2 countries in the world and only 2 commodities are produced in the
world.
There
is perfect mobility of factors of production especially labor, with in the
country, and that there is no mobility of such factors between the 2 countries.
Unit of labor in country are equally
efficient.
Goods
are produced by one factor of production i.e labor in each country, and thereby
is reward determines the cost of production itself.
Transport
cost is excluded on the export and import of goods.
Goods
are produced under the law of constant return or constant costs.
There
are no restriction on the imports and exports of goods between countries which
means that both countries are in a free trade zone.
There
is perfect competition in the labor and product markets.
There
is no problem in the exchange of currencies between the two countries.
(1)There
we are only 2 countries in the world and only 2 commodities are produced in the
world .
(2)There
is the perfect mobility of the factors of production ,especially labour ,with
in the country ,and that there is no mobility of such factors between the 2
countries .
(3)Units
of the labour in the country are equally efficient .
(4)Goods
are produced by one factor production i.e. labour in each country ,and there by
its reward determines the cost of the production itself.
(5)Transport
cost is excluded on the export and import of goods .
(6)Goods
are produced under the law of constant returns /constant costs.
(7)There
are no restrictions on the imports and exports of goods between countries which
means that both countries are in a free trade zone.
(8)There
is perfect completion in the labour and product markets.
(9)There
is no problem in the exchange of currencies between the two countries
Under the above assumptions we
will now apply the theory .As we already know ,international trade takes place
as a result of the comparative costs ,therefore here we will compare the ratio
of cost of production of 2 commodities In the 2 countries .
A country which produce a specialized
product at a competitively lower cost than the other country will then
specialize in its production and export it . this country will only import a
product in which its cost of the production is relatively higher than the other
country and thereby cannot specialize in its production.
