The consequence of this closure is, as in the case of the wholesale diamond market or in other similar communities, a set of effective sanctions that can monitor and guide behavior. In the community in figure 2b, parents A and D can discuss their children's activities and come to some consensus about standards and about sanctions. Parent A is reinforced by parent D in sanctioning his child's actions; beyond that, parent D constitutes a monitor not only for his own child, C, but also for the other child, B. Thus, the existence of intergenerational closure provides a quantity of social capital available to each parent in raising his children-not only in matters related to school but in other matters as well.

DEFINE: Clarifies what 'intergenerational closure' means: connected parent networks that monitor and sanction each other's children. Builds on: "Parental norm enforcement requires intergenerational network closure beyond family relations."
