Although most husbands and wives pool their assets, others hold money
back from the common pot. The choice between ''collectivized '' and ''
privatized'' financial organization depends, in part, on which is more
efficient - which minimizes transaction costs in organizing marital e
xchanges. Insights from the ''new institutional economics'' suggest th
at segregated assets are associated with lower expectations for marita
l continuity, fewer investments unique to the relationship, and ease i
n measuring contributions to the marriage. Data from the Survey of Inc
ome and Program Participation support the notion that couples organize
their finances in order to minimize the transaction costs of married
life.
