For considerable stream the theory of comparative costs formulated past times David Ricardo was the most acceptable explanation of the international trade. However, Ricardo's theory was subjected to number of criticisms.

Following are the of import limitations of Ricardian Comparative Cost Theory.


1. Restrictive Model


Ricardo's Theory is based on alone 2 countries as well as alone 2 commodities. But international merchandise is with many countries with many commodities.


2. Labour Theory of Value


Value of goods is expressed inwards terms of labour content. Labour Theory of value developed past times classical economists has besides many limitations as well as thence is non applicable to the reality.

Value of goods as well as services inwards the existent globe is expressed inwards coin i.e. the prices are the values expressed inwards units of money.


3. Full employment


The supposition of total work helps the theory to explicate merchandise on the footing of comparative advantage. The reality is far from total employment. Cost of production, fifty-fifty inwards terms of labour, may alter every bit the countries, at dissimilar levels of work displace towards total employment.


4. Ignore carry cost


Another serious defect is that the carry costs are non reckon inwards determining comparative cost differences.


5. Demand is ignored


The Ricardian theory concentrates on the render of goods. Each province specialises inwards the production of the commodity based on its comparative advantage. The theory explains international merchandise inwards terms of render as well as takes need for granted.


6. Mobility of ingredient of production


As against the assumptions of perfect immobility betwixt the countries, nosotros witness difficulties inwards the mobility of labour as well as upper-case missive of the alphabet inside a province itself. At the same fourth dimension their mobility betwixt nations was never totally absent.


7. No Free Trade


Ricardian theory assumes gratuitous merchandise i.e. no restriction on the displace of goods betwixt the countries. Though it is unrealistic to assume non to own got whatever restriction. what the existent globe witnesses is a lot tariff as well as non-tariff barriers on international trade. Poor countries notice it hard to bask the comparative wages inwards the production of labour intensive commodities due to the protectionist policies followed past times developed countries.


8. Complete specialisation


The comparative wages theory comes to determination of consummate specialisation. In the Ricardian example, England is specialising fully on stuff as well as Portugal on wine. Such consummate specialisation is unrealistic fifty-fifty inwards 2 countries as well as 2 commodities model. It is possible if 2 countries happens to last well-nigh identical inwards size as well as demand. Again, a consummate specialisation inwards the production of less of import commodity is non possible due to insufficient need for it.


9. Static Theory


The modern economic scheme is dynamic as well as the comparative cost theory is based on the assumptions of static theory. It assumes fixed quantity of resources. It does non reckon the number of growth.


10. Not applicable to developing countries


Ricardian theory is non applicable to developing countries every bit these countries are nowhere nigh to total employment. They are inwards the procedure of alter inwards character of their labour force, character of capital, technology, tapping of novel resources etc. In other words developing countries present all the characteristics of dynamic economy.


11. Constant Returns to Scale


Another drawback of the Ricardian regulation of comparative costs is that assumes constant Returns to scale as well as thence constant cost of production inwards both the countries. The doctrine holds that if England specialises inwards cloth; at that topographic point is no argue why it should gain wine. Similarly if Portugal has a comparative wages inwards producing wine, it volition non gain cloth; only import all stuff from England. If nosotros attempt out the blueprint of international merchandise inwards practice, nosotros notice it is non so. Influenza A virus subtype H5N1 fourth dimension volition come upwardly when it volition non last reasonable for Portugal to import stuff from England because of increasing cost of production. Moreover, inwards actual exercise a province produces a item commodity as well as also imports a purpose of it. This phenomenon has non been explained past times the theory of comparative costs.
