My five pounds are not as good as yours, so I will spend them
通过实验研究货币面额和硬币与纸币的选择如何影响消费者的购买行为，发现消费者可能更喜欢小面额纸币而非大面额硬币，且携带硬币的人更可能进行小额购买。
Abstract An experimental approach is used to examine how money denomination and the choice between or availability of coins and banknotes may influence consumers’ purchasing behaviour. Evidence shows that for small amounts of money, consumers may prefer a smaller monetary value in banknotes rather than a higher value in coins. Findings also suggest that people carrying coins are more likely to make a purchase of small value than people not carrying coins.
