noun
pump-priming economic policy
A Keynesian-style policy where government spending is used to stimulate private investment and economic activity, like pouring a small amount of water into a pump to get it started.
不況対策として、政府は呼び水式経済政策を実施した。
As a countermeasure against the recession, the government implemented a pump-priming economic policy.
Compound of 呼び水 (pump priming, literally 'calling water') + 式 (style) + 経済 (economy) + 政策 (policy). The term 呼び水 is a metaphor for a small initial stimulus that triggers a larger flow.
