种群中雄性与雌性的比例是决定动物行为的一个重要因素。我们认为性别比例对人类也有普遍的影响，比如影响经济决策。利用历史数据和实验，我们研究了性别比例如何影响美国的储蓄，借贷和支出。研究结果表明，男性偏见的性别比例（男性过多）导致男性对未来不抱希望，渴望立即获得回报。偏向男性的性别比例降低了男性为未来储蓄的愿望，并增加了他们为眼前支出而负债的意愿。性别比例似乎通过增加同性之间争夺配偶的激烈程度来影响行为。因此，女性的稀缺导致人们期望男性在求爱期间花更多的钱，比如花更多的钱买订婚戒指。这些发现通过实验证明，性别比例影响人类决策的方式与进化生物学理论一致。跨文化的性别比例效应的影响进行了讨论。
The ratio of males to females in a population is an important factor in determining behavior in animals. We propose that sex ratio also has pervasive effects in humans, such as by influencing economic decisions. Using both historical data and experiments, we examined how sex ratio influences saving, borrowing, and spending in the United States. Findings show that male-biased sex ratios (an abundance of men) lead men to discount the future and desire immediate rewards. Male-biased sex ratios decreased men’s desire to save for the future and increased their willingness to incur debt for immediate expenditures. Sex ratio appears to influence behavior by increasing the intensity of same-sex competition for mates. Accordingly, a scarcity of women led people to expect men to spend more money during courtship, such as by paying more for engagement rings. These findings demonstrate experimentally that sex ratio influences human decision making in ways consistent with evolutionary biological theory. Implications for sex ratio effects across cultures are discussed.
