bolster economic growth
No definition. No dictionary. Just the sentence, made better.

The Common Mistake
Many IELTS candidates lean on improve, help and increase.
“Improve” and “help” are correct — but generic. They miss the sense of actively reinforcing something that is already under pressure or at risk of weakening.
“Yes — that's exactly how I write, too.”
Section 03
The Better Choice
This is the step from Band 6 to Band 7 — not a harder word, a more precise one.
Section 04
Why It Works
“Improve” just says something got better. “Bolster” says you actively strengthened or reinforced something that was weak or under threat — support given right at the point of need.
That is why economics and policy writers reach for it. It pairs with abstract nouns of strength and confidence (confidence, economy, support, morale, defences) — the exact collocations Band 8 rewards.

Upgrade Matrix
Watch one idea climb from Band 6 to Band 9 — same meaning, rising precision.
The government spent money to help the economy.
Correct, but “help the economy” is vague and informal.

Stronger verb, though the object could be sharper.
The government introduced tax cuts to bolster economic growth.
Natural collocation + a concrete measure. This is the target.
The government introduced targeted tax cuts to bolster economic growth amid rising global uncertainty.
Developed idea with context — fully controlled.
Praise from teachers can help a student's confidence.
Fine, but flat and slightly informal.
Regular praise from teachers can bolster a student's confidence.
“Bolster confidence” is a top-tier academic collocation.
Consistent, specific praise from teachers can significantly bolster a student's self-confidence and motivation.

Section 06 · Read against the band descriptors
Examiner's Insight
How this word measures up against the public IELTS Writing & Speaking band descriptors — an editorial read, not a real examiner's verdict.
In Writing Task 2, “bolster economic growth” is the kind of phrasing the band descriptors reward — not because the word is rare, but because it captures reinforcement under pressure precisely. It signals control of collocation and register, not just a bigger vocabulary.
Section 07
Native Radar
Not about grammar — about whether a native speaker would actually say it.
-
Native would naturally say
measures to bolster public confidence in the justice system
-
Native might say
bolster your muscles
Understood — but for physical strength gained through exercise, “build” or “strengthen” sounds more natural in everyday English.
-
Native almost never says
bolster unemployment
Bolster strengthens something you want to keep or grow — not a problem you want to reduce.

Answer
bolster — “bolster public safety” is a natural pairing.

not just improve it.
If you forget everything else, keep this.

Final Verdict
Bolster is one of the most useful verbs in academic and economic English. It is not a rare word you show off — it names a specific act: reinforcing something that is under strain. The moment you write “bolster public confidence” instead of “improve public confidence,” your writing signals you understand where the pressure is and what is being done about it.
Learn it once, pair it with nouns of strength and support — confidence, economy, support, defences, morale — and it will strengthen most economy, policy and society essays you write.
