More than two decades of work towards liberating scholarly publishing from paywalled constraints ... more More than two decades of work towards liberating scholarly publishing from paywalled constraints has left many within the scholarly community exploring ways to accelerate the transition to open access. Not all institutions or author communities will agree upon which strategies or funding approaches to undertake, and nor do they need to. But whichever strategy is pursued, having university faculty lead the charge represents the most effective way forward. Rachael G. Samberg, Richard A. Schneider, Ivy Anderson and Jeff MacKie-Mason share the University of California’s range of open access policy and advocacy materials, and highlight some potential next steps that may be of use to faculty and author communities.

A diverse group of products, such as dishwashers, automobiles, and highly complex electronic equipment (computers, telephone switches, medical imaging devices, etc.), spawn service markets. Typically, the first firm offering service to owners of durable equipment is the original equipment manufacturer (OEM) itself; after all, it already has parts and expertise. Often, the only service provider is the manufacturer. The broad question in this paper is the effect on the manufacturer and on consumers if a manufacturer is the only service provider for equipment it sells.

Answers, Wikipedia, and YouTube have drawn much media attention. Various reasons motivate the tremendous contributions to a few UCC systems so far. Existing literature has uncovered many factors that affect users' decisions to become contributors [Bryant et al., 2005], to continue contributing [Nov, 2007], and to increase contribution [Chen et al., 2007], but none of them pay attention to why active contributors decide to stop contributing. The exit of ...

The defining characteristic is that much of the information provided by a producer is donated to the producer, by people not employed by the producer. There are several names for this production technology; we favor user-contributed content (typically there is no boundary between contributors and users of the content). 1

Such bilateral feedback giving introduces strategic considerations. We focus on reciprocity in the giving of feedback: how prevalent a strategy of giving feedback is only if feedback is first received from one's trading partner. The overall level of feedback activity clearly depends on the prevalence of the reciprocation strategy: in a market with many reciprocators and few unconditional feedback providers, the equilibrium quantity of feedback can be quite low. We estimate the prevalence of such reciprocation in one market, eBay. Reciprocation cannot be directly distinguished from late feedback that was not conditioned on the partner having provided feedback. We develop a model that distinguishes the two by exploiting information about the timing of feedback provision when the partner does not provide feedback. We find that buyers and sellers on eBay used the reciprocate only strategy about 20-23% of the time. We also measure the extent to which the prevalence of these strategies changes with the experience levels of the two parties and with the item price.
