Commodity Terms of Trade Shock: Estimate national-income exposure to export and import commodity price changes.

Age 5Explain it to a 5-year-oldStart with a picture

Imagine using Commodity Terms of Trade Shock to answer this question: estimate national-income exposure to export and import commodity price changes? Enter Annual commodity exports, Export commodity price change, Annual commodity imports, and 2 other inputs; the calculator shows Illustrative net national-income effect. Try changing one number and watch what happens to Illustrative net national-income effect. The answer tells you Illustrative net national-income effect.

Age 15Explain it to a 15-year-oldConnect it to the formula

Volumes, hedging, taxes, ownership and exchange rates determine how much of the price shock reaches residents. The rule is Net income effect = commodity exports × export-price change − commodity imports × import-price change. Its input values are Annual commodity exports, Export commodity price change (%), Annual commodity imports, Import commodity price change (%), Nominal GDP, and the main result is Illustrative net national-income effect. Try changing one number and watch what happens to Illustrative net national-income effect.

CollegeExplain it at college levelState the model precisely

This calculator evaluates a macroeconomics relationship while holding unmodelled conditions constant. The implemented relation is Net income effect = commodity exports × export-price change − commodity imports × import-price change, evaluated from Annual commodity exports, Export commodity price change (%), Annual commodity imports, Import commodity price change (%), Nominal GDP to produce Illustrative net national-income effect. Volumes, hedging, taxes, ownership and exchange rates determine how much of the price shock reaches residents. The result depends on comparable definitions, units, populations and time periods. It estimates a relationship; it does not establish causation or replace current primary data.

The economic question

Estimate national-income exposure to export and import commodity price changes.

Why this relationship is useful

Volumes, hedging, taxes, ownership and exchange rates determine how much of the price shock reaches residents.

Inputs that must be comparable

  • Annual commodity exports.
  • Export commodity price change measured in %.
  • Annual commodity imports.
  • Import commodity price change measured in %.
  • Nominal GDP.

Use one market, firm, population and time period throughout; mixing definitions can make a correctly calculated number economically meaningless.

The model

Net income effect = commodity exports × export-price change − commodity imports × import-price change

From inputs to output

The calculator combines Annual commodity exports, Export commodity price change, Annual commodity imports, Import commodity price change, Nominal GDP and reportsIllustrative net national-income effect together with Effect as share of GDP, Gross export-price effect. Change one assumption at a time to identify what actually drives the estimate.

How to read Illustrative net national-income effect

Read the sign, magnitude, unit and period together. The result quantifies the relationship in “estimate national-income exposure to export and import commodity price changes”; it does not by itself prove that one input caused another.

Where interpretation can fail

Do not use the result when the input definitions, units or formula assumptions do not match the real situation. This is an educational model, not financial, investment, tax or policy advice; verify material decisions against primary data and professional guidance.
