Explain in IB Economics

What your response needs

Initial change → behavioural response → curve change → disequilibrium/adjustment → new outcome.

• A clear starting economic change
• A mechanism using explicit causal links
• The relevant curve shift or movement
• A final effect on economic variables
• Case evidence when supplied

A worked economics example

Question: Explain how an increase in interest rates may reduce inflation.

An incomplete response: Higher interest rates reduce inflation because people spend less.

A more complete response:

A higher interest rate increases the cost of borrowing and the reward for saving.

Interest-sensitive consumption and investment fall.

Because C and I are components of aggregate demand, the AD curve shifts left.

The resulting fall in demand-pull pressure lowers the rate of inflation, ceteris paribus.

Common mistakes to avoid

• Repeating the assertion using different words
• Jumping from cause to final effect with no mechanism
• Confusing a decrease in aggregate demand, shown by a leftward AD shift, with a movement along AD
• Adding evaluation instead of completing the explanation

Try it yourself

Read the question and its mark allocation before deciding how much detail to include. A response structure helps you organise your answer; it is not a script to memorise.
