Introduction:

In economics, Terms of Trade means the rate at which one country’s goods exchange for the goods of another country. It reflects the relationship between the prices of a country’s exports and the prices of its imports.

Meaning:

In short, terms of trade mean the term on which two countries trade with each other. Example: suppose country A is exporting 1 unit of cotton to country B and in return gets from it 1 unit of wheat then the ratio of exchange is also called terms of trade is 1:1. Terms of trade can be favorable as well as unfavorable.

Definition:

Terms of Trade = (Index of Export Prices / Index of Import Prices) × 100

• If the terms of trade is > 100 → The country can import more for every unit of export (favorable).
• If the terms of trade is< 100 → The country must export more to import the same amount (unfavorable).

Components of terms of trade:

The components of Terms of Trade (TOT) refers to the different elements or types that help analyze and understand how a country’s trade is performing. These components show how prices, quantities, and productivity in trade influence a country’s economic relationship with the rest of the world.

1. Net barter terms of trade: The concept of net terms of trade is the contribution of J.S. mill and Alfred Marshal. it is the ratio of the index of export prices to the index of import prices. It is obtained by dividing the index of export prices by the index of import prices. It may be noted that are index of export prices the index of import prices and the ratio between the two that is the quotient thus obtained are expressed in percentage. In symbols the net barter terms of trade is expressed as follows P_X/P_m*100. Here PX stand for index number of export prices and pm is for index number of import prices. Examples: suppose index number of export prices of a country A is 200 and index number of import prices of commodity country A is 100 then the net barter terms of trade will be 200/100*100=200%
2. Gross barter terms of trade: The concept of gross barter terms of trade was introduced by professor Tausig. Gross barter terms of trade refer to the rate of exchange between the whole of a country’s physical export and the whole of the country’s physical imports. It is obtained by diving the index of the physical quantity of exports by the index of the physical quantity of imports. In symbols the gross barter terms of trade is expressed as Q_X/Q_M*100. Here Q_X stands for the index number of quantity of exports, Q_M stands for the index number of quantity of imports.
3. Income terms of trade: the concept of income terms of trade has been introduced by G.S Durance. The income terms of trade are also referred to as a country’s capacity to import. The income terms of trade is obtained by dividing the value of exports by the index of import prices. n symbols the income terms of trade is Q_X*P_Y/Pm*100. Q_X represents quantity index of exports. P_Y represents the price index of exports and Pm stands for the index imports price.
4. Single Factorial Terms of Trade (SFTT): It is an improved and more realistic version of the Net Barter Terms of Trade (NBTT). It adjusts the NBTT by taking into account the productivity of a country’s export sector. It shows how many imports a country can obtain per unit of real cost (effort or input) of its exports. It also reflects the real gain from trade after accounting for improvements in production efficiency. A higher SFTT means better trade advantage, as the country uses fewer resources to produce exports and gets more imports in return. The formula is SFTT=NBTT× Export Productivity Index Where: NBTT = Net Barter Terms of Trade Export Productivity Index = A measure of how efficiently a country produces its export goods
5. Double Factorial Terms of Trade (DFTT): It is a refined and theoretical concept in international economics that adjusts the Net Barter Terms of Trade (NBTT) by considering productivity changes in both the export sector of the home country and the import sector of the foreign country. DFTT shows how many units of domestic productive effort are exchanged for foreign productive effort. Thus, it evaluates the real cost-benefit exchange between two nations, considering technological and productivity differences. Formula: DFTT= NBTT× Export Productivity Index divided by import productivity x 100.
6. ​Real Cost Terms of Trade (RCTT): It is a theoretical concept in international trade that adjusts the Single Factorial Terms of Trade (SFTT) by taking into account the real cost (such as labor, time, effort, or opportunity cost) incurred by a country to produce its exports. Formula: RCTT= SETT devided by index of real cost in export.( Index of Real Cost means how much real effort (like labor time or economic resources) is used in export production)
7. Utility Terms of Trade (UTT): It is a highly theoretical and abstract concept in international economics. It measures a country’s terms of trade based on the utility or satisfaction derived from the imports it receives in exchange for its exports. UTT focuses on the level of utility (satisfaction) a country’s population gains from the imported goods. Formula: UTT x utility (satisfaction) from imports divided by real cost of exports.
