Adolescent romantic relationships are sources of social influence concerning educational achievement and delinquent behavior. Integrated schooling is known to induce inter-ethnic friendship relations, however, it also creates the opportunity of inter-ethnic dating. Based on contact theory, inter-ethnic personal relationships or long-term exposure decreases ethnic prejudice, thus it is proposed ...

We propose a two-sided method to simultaneously estimate men’s and women’s preferences for relative age, education and religious characteristics of potential mates using cross-sectional data on married couples and single individuals, in conjunction with a behavioral model developed in game theory (Roth and Sotomayor 1990) and discrete choice estimation methods developed for simpler, one-sided c...

A multi-locus model for complete positive assortative mating is discussed. For a two-locus model, if the gene frequencies for the two loci are different, as they are likely to be, it is shown that in equilibrium the population is not composed of only two homozygous types, as is usually thought. The limiting distribution will have three homozygous genotypes depending upon the initial gene freque...

There has been growing interest in the possibility that biological factors, including genes, might contribute to differences in political and social behavior. Over the last 40 years, human statistical and behavioral genetics have developed a variety of models that allow the effects of genetic and non-genetic inheritance to be estimated from human kinship data. Until quite recently, these method...

In light of recent changes in the labor force participation and socioeconomic standing of women, we ask whether a woman's position in the labor market has become more important over time as a determinant of her position in the marriage market. To test this hypothesis, we examine change over time in the association of wives' wages and husbands' socioeconomic standing, using data on first marriag...

Researchers have debated for 134 years whether birth order has long-term effects on the development of a child, and so far no consensus has emerged. In addition to practical applications and relevance to the study of personality, birth order effects are an important test case for theories about how and whether home environment affects the adults children become (Pinker, 2002; Sulloway, 1996). I...
