The Text Analysis Conference (TAC) ranks summarization systems by their average score over a collection of document sets. We investigate the statistical appropriateness of this score and propose an alternative that better distinguishes between human and machine evaluation systems.

Regardless of whether you agree with the appropriateness of such labels as the Information Age or the Information Society, their ubiquitous use signals and frames the collective experience of who we are and what we should do in this particular time and place in history. From information acquisition and anxiety to information warfare and weapons, there are few areas of social life that are left ...

We study the formation of gender identity by looking at the labor-market decisions of young women. Specifically, we investigate whether and how a woman’s work behavior depends on the work behavior of her mother and that of her friends’ mothers. Using a representative sample of U.S. teenagers and their schoolmates followed over time, we find that both intergenerational channels positively affect...

A folk theorem for repeated matching games is established that holds if the stage game is not a pure coordination game. It holds independent of population size and for all matching rules—including rules that depend on players choices or the history of play. This paper also establishes an equilibrium condition and using this discovers two di¤erences between the equilibria of repeated matching ga...

Sustaining cooperation among self-interested agents is critical for the proliferation of emerging networked communities, such as the communities formed by social networking services. Providing incentives for cooperation in networked communities is particularly challenging because of their unique features: a large population of anonymous agents interacting infrequently, having asymmetric interes...
