Final answer:
Keith Chen's experiment explored the relationship between language structure and money-saving habits, suggesting that language can influence economic behavior.
Step-by-step explanation:
In Keith Chen's TED Talk, he discusses an experiment centered around money-saving habits. Chen carried out a study exploring the relationship between language structure and behavioral economics, specifically how the language we speak can affect our propensity to save money. He found that speakers of languages without a future tense, like Chinese, are more likely to save money than speakers of languages with a distinct future tense, like English. This suggests a connection between language and how we perceive and act upon the concept of the future, impacting economic behavior.
