We examine a rapidly emerging regulatory approach that we label "management-based regulation." Management-based regulation shifts the locus of policy discretion from the government regulator to the regulated entity. Government directs private firms to incorporate public goals into their...

Whether as team members brainstorming, or cultures experimenting with new technologies, problem solvers communicate and share ideas. This paper examines how the structure of these communication networks can affect system-level performance. We present an agent-based model of information sharing,...

How do decentralized systems collectively solve problems? Here we explore the interplay among three canonical forms of collective organization--markets, networks, and hierarchies--in aggregating decentralized problem solving. We examine these constructs in the context of how the offices of...

Do legislators learn to use new communication technologies from each other? Using data from the official homepages of members of the U.S. House of Representatives, we test whether web-based communication technology diffuses through congressional state delegations. We use a natural experimental...

How do political views and social affiliations co-evolve? A long stream of research has focused on the relationship between political views and social affiliations, however, it is typically difficult to discern the causal relationship between views and affiliations. Here we use longitudinal...
