In a polygamous society, all monogamous women are virtually at risk of polygamy. However, both the anthropological and economic literature are silent on the potential impact of the risk of polygamy on economic decisions of monogamous wives. We explore this issue for Senegal using individual panel data. We first estimate a Cox model for the probability of transition to polygamy. Second, we estim...

Hypergamy, Cross-Boundary Marriages, and Family Behavior We study the rise in marriages between residents of HK and China following the handover of HK to China in 1997. Cross-boundary marriages accounted for almost half the marriages registered in HK in 2006. Because of large differences in male income between China and HK, marriages of HK men with Mainland women outnumbered those of HK women w...

Mismeasured Household Size and Its Implications for the Identification of Economies of Scale We consider the possibility that demographic variables are measured with errors which arise because household surveys measure demographic structures at a point-in-time, whereas household composition evolves throughout the survey period. We construct and estimate sharp bounds on household size and find t...

The theory of Markov decision processes (MDP) can be used to analyze a wide variety of stopping time problems in economics. In this paper, the nature of such problems is discussed and then the underlying theory is applied to the question of arranged marriages. We construct a stylized model of arranged marriages and, inter alia, it is shown that a decision maker' s optimal policy depends only on...

Almost 50 years after domestic US family planning programs began, their effects on childbearing remain controversial. Using the county-level roll-out of these programs from 1964 to 1973, this paper reevaluates their shorter and longer term effects on US fertility rates. I find that the introduction of family planning is associated with significant and persistent reductions in fertility driven b...

Does Parental Divorce Affect Adolescents' Cognitive Development? Evidence from Longitudinal Data In this paper we analyse data from the National Education Longitudinal Study of 1988 to investigate whether experiencing parental divorce during adolescence reduces measured cognitive ability. To account for the potential endogeneity of parental divorce we employ a difference-in-differences model th...

This paper uses Propensity Score Matching to investigate the causal effect of breastfeeding on children’s cognitive development. There is a strong association between breastfeeding and cognitive outcomes; however, it is notoriously difficult to establish whether this is causal, or whether it arises because mothers who breastfeed tend to be those whose children would do better anyway. Using PSM,...

This paper presents an evolutionary model to explain the widespread diffusion of lifelong monogamous families. The essential condition, unique to humans, is the overlap of children of different ages. Under this condition, together with the salience of paternal investment and fatherhood uncertainty, monogamy attains a greater survivorship than serial monogamy and polygyny. This result is robust ...

I provide new evidence on the relative “powers” of contraception and abortion policy in effecting the dramatic social transformations of the 1960s and 1970s. Trends in sexual behavior suggest that young women’s increased access to the birth control pill fueled the sexual revolution, but neither these trends nor difference-in-difference estimates support the view that this also led to substantia...

This paper intends to provide an evaluation of where the economic research on happiness stands and in which interesting directions it might develop. First, the current state of the research on happiness in economics is briefly discussed. We emphasize the potential of happiness research in testing competing theories of individual behavior. Second, the crucial issue of causality is taken up illus...
