Gross Barter Terms of TradeMeasures the physical ratio of total import quantities to total export quantities, expressed as $\frac{Q_m}{Q_x} \times 100$ .
Income Terms of TradeMeasures a nation's total capacity to import goods based on export earnings, expressed as $\frac{P_x}{P_m} \times Q_x$ .
Single Factoral Terms of TradeAdjusts commodity terms of trade for productivity changes specifically within the domestic export sector, expressed as $\frac{P_x}{P_m} \times Z_x$ .
Double Factoral Terms of TradeAdjusts commodity terms of trade for productive efficiency changes in both domestic export and foreign import industries, expressed as $\frac{P_x}{P_m} \times \frac{Z_x}{Z_m}$ .

Cevap

Gross Barter Terms of Trade corresponds to the physical import-to-export volume ratio ($\frac{Q_m}{Q_x} \times 100$); Income Terms of Trade corresponds to the capacity to import ($\frac{P_x}{P_m} \times Q_x$); Single Factoral Terms of Trade corresponds to domestic export sector productivity adjustment ($\frac{P_x}{P_m} \times Z_x$); Double Factoral Terms of Trade corresponds to productivity adjustment in both domestic export and foreign import sectors ($\frac{P_x}{P_m} \times \frac{Z_x}{Z_m}$).

Gross Barter Terms of Trade measures the physical volume relationship between imports and exports. Income Terms of Trade measures the purchasing power of exports (capacity to import). Single Factoral Terms of Trade adjusts commodity terms of trade for productivity improvements in the domestic export sector, whereas Double Factoral Terms of Trade incorporates productivity changes in both the home export sector and foreign import-producing sector.

Adım Adım Çözüm

Define Gross Barter Terms of Trade

Identified as the physical volume ratio of imports to exports:

\frac{Q_m}{Q_x} \times 100

Gross barter terms focus on physical quantities traded rather than monetary price indices.

Define Income Terms of Trade

Identified as total capacity to import:

\frac{P_x}{P_m} \times Q_x

Income terms of trade weigh price ratios against actual export quantity to measure import capacity.

Differentiate Single Factoral from Double Factoral Terms of Trade

Single Factoral adjusts for domestic export sector productivity (

Z_x

), while Double Factoral adjusts for both domestic export (

Z_x

) and foreign import (

Z_m

) sector productivities.

Factoral terms of trade incorporate input productivity indices into commodity price terms of trade.
