Proposal Number: 0527751Mobarak, AhmedUniversity of Colorado BoulderConsanguineous marriages remain common practice in much of the developing world despite their well-documented biological and genetic risks for the offspring of such unions. The objective of this study is to theoretically account for and empirically document the socio-economic benefits of consanguineous unions that help to sustain these types of marriages. A collective model of intra-household allocation and assortative spousal matching motivates the empirical investigation. The model predicts that for spouses and their children, the economic benefits of consanguineous marriages should depend on spousal incomes, the autonomy of spousal income from parental income, and external distribution factors like the sex ratio, cultural gender norms, and marriage/divorce legislation. Using existing as well as yet-to-be-gathered data from fourBangladeshi communities, the project will (a) document the prevalence of consanguinity for a country for which such numbers currently do not exist, (b) quantify the trade-off between the biological risks and any possible socio-economic benefits (in terms of long-run outcomes for children) of consanguinity, (c) study decision-making in the marriage market, including the characteristics of potential spouses that families consider to be most attractive, and (d) investigate the creation of international migration links through marriage. The dataset that will be produced will allow researchers in Economics, Sociology, Biology, Genetics and the Medical Sciences to study a variety of questions relating to intra-household decision-making, the nature of social networks, and the risk of genetic disorders stemming from consanguinity. The proposed research is a unique cross- and multidisciplinary approach to the question of trade-offs between the perceived social and economic benefits of consanguineous marriage as opposed to the recognized biological disadvantages. Bangladesh, a country of over 140 million is undergoing an epidemiological transition from a predominantly infectious to a non-communicable disease profile, is an ideal setting for the study, and the growing numbers of Bangladeshis now resident in Western countries add a significant new dimension to the work. Study findings are potentially generalizable to countries and societies currently undergoing transition from predominantly infectious to non-communicable disease profiles.

提案编号：0527751莫巴拉克，艾哈迈德科罗拉多大学博尔德大学血缘婚姻在许多发展中国家仍然很普遍，尽管这种婚姻的后代面临着有据可查的生物和遗传风险。这项研究的目的是从理论上解释和实证记录有助于维持这些类型婚姻的血亲结合的社会经济利益。家庭内部分配和分类配偶匹配的集体模型激励了实证研究。该模型预测，对于配偶及其子女来说，近亲婚姻的经济利益应取决于配偶收入、配偶收入与父母收入的自主性以及性别比例、文化性别规范和结婚/离婚立法等外部分配因素。利用孟加拉国四个社区现有的以及尚未收集的数据，该项目将：(A)记录目前没有这种数字的国家的血缘关系的普遍程度；(B)量化血缘关系的生物风险与任何可能的社会经济利益(儿童的长期结果)之间的权衡；(C)研究婚姻市场的决策，包括家庭认为最具吸引力的潜在配偶的特征；以及(D)调查通过婚姻建立国际移徙联系的情况。将产生的数据集将允许经济学、社会学、生物学、遗传学和医学的研究人员研究与家庭内部决策、社会网络的性质以及源于血缘关系的遗传疾病风险有关的各种问题。拟议的研究是一种独特的跨学科方法，旨在权衡近亲婚姻的社会和经济利益与公认的生物劣势之间的权衡问题。孟加拉国是一个人口超过1.4亿的国家，正在经历从传染病为主向非传染性疾病的流行病学转变，是开展这项研究的理想环境，目前居住在西方国家的孟加拉人越来越多，这为这项工作增添了一个重要的新层面。研究结果可能适用于目前正在从主要传染性疾病向非传染性疾病转型的国家和社会。
