Interdependent Preferences, Militarism, and Child Gender

Selection effects make it difficult to determine whether concern for other people genuinely affects individuals’ policy preferences. Child gender provides a conveniently exogenous means of exploring the issue, especially in contexts such as military policy where girls and boys face different risks; in many countries male children are disproportionately likely to become soldiers and thus bear the costs of militarism. This creates divergent effects: those in households with girls generally prefer more hawkish foreign policies than do members of households with boys. Data from the 2004 American National Election Study confirm these intuitions, both in general statements of policy preference and in evaluating the net costs of the Afghanistan and Iraq conflicts.
