This paper studies how to form an efficient coalition—a group of people. More specifically, we compare two mechanisms for forming a coalition by running laboratory experiment and reveal which mechanism leads higher social surplus.

Here, we focus on a particular aspect of the advertising content choice: an attribute-focused appeal versus an appeal with no direct information on product attributes. We make two assumptions that capture the reality of the advertising context. First, we assume that the bandwidth of advert...

In this easy introduction to higher gauge theory, we describe parallel transport for particles and strings in terms of 2-connections on 2-bundles. Just as ordinary gauge theory involves a gauge group, this generalization involves a gauge ‘2-group’. We focus on 6 examples. First, every abelian Lie group gives a Lie 2-group; the case of U(1) yields the theory of U(1) gerbes, which play an importa...
