The role of height in the sex difference in intelligence.

Recent studies conclude that men on average have higher intelligence than women by 3-5 IQ points. However, the ultimate evolutionary question of why men should have evolved to have higher intelligence than women remains. We suggest that men may have slightly higher intelligence than women through 4 mechanisms: (1) assortative mating of intelligent men and beautiful women, (2) assortative mating of tall men and beautiful women, (3) an extrinsic correlation between height and intelligence produced by Mechanisms 1 and 2, and (4) a higher-than-expected offspring sex ratio (more sons) among tall (and hence intelligent) parents.

Strategic mating with common preferences.

We present a two-sided search model in which individuals from two groups (males and females, employers and workers) would like to form a long-term relationship with a highly ranked individual of the other group, but are limited to individuals who they randomly encounter and to those who also accept them. This article extends the research program, begun in Alpern and Reyniers [1999. J.

Strategic mating with homotypic preferences.

We determine equilibrium acceptance strategies in a class of multi-period mating games where individuals prefer opposite sex partners with a close parameter type (one-dimensional homotypic preferences). In each period unmated individuals are randomly paired. They form a couple (and leave the pool) if each accepts the other; otherwise they continue into future periods.
