儿童可被视为公共产品，父母双方可获得同等的遗传利益，但父母一方往往比另一方投资更多。我们介绍了一个微观经济框架，了解家庭投资决策，以解决有关的问题，在已婚男性和女性之间的工作努力的类型和数量的利益冲突。虽然婚姻的收益和成本可能不会在婚姻伴侣之间平均分配，但在各种条件下，婚姻仍然是一个有利的，有效的结果。这个生物经济学框架包含了关于性别分工的合作和冲突观点。我们测试假设婚姻市场，自愿交配，和男子的劳动动机之间的Tsimane觅食，园艺玻利维亚，并发现：（1）男女都重视配偶的工作努力，（2）婚姻劳动贡献是互补的，（3）配偶之间的工作努力是相关的，（4）总生产与总再生产相关，（5）更好的猎人在婚姻中有更高的适应度增益。
Children may be viewed as public goods whereby both parents receive equal genetic benefits yet one parent often invests more heavily than the other. We introduce a microeconomic framework for understanding household investment decisions to address questions concerning conflicts of interest over types and amount of work effort among married men and women. Although gains and costs of marriage may not be spread equally among marriage partners, marriage is still a favorable, efficient outcome under a wide range of conditions. This bioeconomic framework subsumes both cooperative and conflictive views on the sexual division of labor. We test hypotheses concerning marriage markets, assortative mating, and men's labor motivations among Tsimane forager-horticulturalists of Bolivia and find that: (1) men and women both value work effort in marital partners, (2) marital labor contributions are complementary, (3) work effort is correlated between spouses, (4) total production is correlated with total reproduction, and (5) better hunters have higher fitness gains within marital unions.
