The ‘centres of excellence’ policy implicitly pursued through the RAE is an optimal allocation strategy only if all departments in all disciplines are of the generalist variety, i.e. each pursues a research path through all its stages. Conversely, the RAE-induced research allocation minimizes efficiency if applied to specialist departments, when resources are concentrated on one specific research obstacle. It is argued that the RAE should not take the organization of University research as exogenous, but rather should encourage specialization. All results are obtained by applying to University research concepts and solutions borrowed from the mathematical theory of systems reliability.

The New Industrial Economics focuses on key issues including entry deterrence, product differentiation, pricing policy, strategic behaviour, research and development which are examined in the light of the most recent developments in game theory. Each chapter is designed to present the results of frontier research in a relatively non-technical manner suitable for intermediate level undergraduate students.

It is assumed that a state-owned enterprise (SOE) maximizes an increasing function of output, subject to a break-even constraint. We first show that, because of instability, the industry cannot contain more than one SOE. Then we establish an irrelevance result: if the SOE's cost disadvantage relative to private firms is not too large, then aggregate output, aggreagte costs and welfare are the same with and without the SOE. However, for this range of cost disadvantage an SOE monopoly yields higher welfare. Implications for privatization policy are suggested.

This paper argues that it is both feasible and desirable lo allow multiple prizes. Indeed, it is possible that complete abolition of the patent system, by raising the returns to late finishers, would yield an improvement on the current situation. 'A British court has just decreed that Genentech, a biotechnology company in California, cannot retain exclusive marketing rights in Britain for its heart product, TPA. The judge ruled that the terms of the patent were too broad (.. .) To stop others working (.. .) would stifle research and not be in the public interest. Genentech plans to appeal against the decision. If its patent were to stick, 19 companies would have to abandon their work on their TPAs.'

They provide a general formulation of the two-player two-strategy game applied to the state of nature and derive existing models as special cases. A nonstandard version of Chicken under incomplete information, that interprets “death” as infinitely bad, provides an explanation for important and hitherto unaccounted for claims by Hobbes. The authors suggest that rational choice in Hobbesian political philosophy ought to examine not so much the mechanics of rational action in natural conditions, but rather the means whereby citizens already living in civil associations can be persuaded of the irrationality of civil war.

The main point raised by Alexander Coram is that the cost of (uncertain) death cannot be infinite. So, either we were incorrect in ascribing to Hobbes such a preposterous claim or, if Hobbes did make such a claim, so much the worse for him, for the notion of an infinitely bad payoff being attached to death is just nonsensical and counterfactual. Related to this substantive issue is the less interesting observation that infinity is not a real number and cannot be treated as such in calculating probabilities at a mixed-strategy equilibrium. It is our contention that Hobbes's political theory is indeed predicated on one particular type of death being infinitely evil (not just really, really bad) and that our attempt to formalize his construct is as consistent as the rational-actor approach permits. The context in which we introduced the assumption that "violent death at the hands of others" is infinitely evil (assumption S°°^ is of paramount importance to understand why death being infinitely bad not only is not "meaningless," but is indeed a cornerstone of Hobbes's political theory. The examples cited by Coram as instances of people taking

As a result, and contrary to conventional wisdom, product quality may be identical under the two regimes. * I wish to thank David de Meza, Stanislaw Gomulka and the Editors for their comments on previous drafts.

Current initiatives to collate views data across publishers and institutional repositories, validating the data using the COUNTER protocol, are unlike to succeed because they are predicated on the concept of central clearing-house which is expensive to maintain and not scalable. The BitViews project uses open-source blockchain technology (a distributed publicly-accessible ledger protecting the privacy of viewing data) and thus provides a low-cost solution which bypasses the need for a central clearing house. As soon as online usage data are aggregated on a worldwide basis, they provide the raw material for devising discipline-specific non-citation impact metrics. Authors of scientific, scholarly, and medical peer-reviewed outputs will have a s...

Research paper thumbnail of BitView: Using Blockchain Technology to Validate and Diffuse Global Usage Data for Academic Publications

Maturity and Innovation in Digital Libraries, 2018

Previous attempts to create online usage metrics have been unsuccessful largely because it has been difficult to coordinate agreement between all parties on the rules of data collection and the distribution of the workload of data synthesis and dissemination. Blockchain technology can be utilized to bypass this coordination problem. We propose the creation of a bibliometric blockchain (called BitView) which forms a decentralized ledger of the online usage of scholarly research outputs. By means of a worked example, we demonstrate how this blockchain could ensure that all parties adhere to the same rules of data collection, and that the workload of data synthesis is distributed equitably. Moreover, we outline how public-private key cryptography could ensure that users' data remains private while librarians, academics, publishers, and research funders retain open access to all the data they require. It is concluded that a usage metric underpinned by blockchain technology may lead to a richer and healthier ecosystem in which publishers and academics are incentivized to widen access to their research.

It creates a free public ledger of usage events that allows anyone to see which research outputs have been accessed, where, and when, thus providing the raw material to construct discipline- and region-specific non-citation based measures of research impact. BitViews’ short-term implications include: 1.The re-alignment of journal impact measures (from citations to usage); 2.Changed patterns in the production of research articles (towards high- usage topics); 3.Creation of new networks of research collaboration; 4.Enhanced opportunity for open data sharing. BitViews’ long-term effects are transformative. Because BitViews promotes the “unbundling” of AAMs from published articles, it endows AAMs with independent value. Two disruptive consequences follow: the very concept of APCs is undermin...

The former can be seen as the public good that ought to be openly accessible, whereas the latter is owned by publishers and rightly paywall-restricted. We propose one such mechanism to overcome this obstacle: BitViews. BitViews is a blockchain-based application that aims to revolutionize the OA publishing ecosystem. Currently, the main academic currency of value is the citation. There have been attempts in the past to create a second currency whose measure is the online usage of research materials (e.g. PIRUS). However, these have failed due to two problems. Firstly, it has been impossible to find a single agency willing to coordinate and fund the validation and collation of global online usage data. Secondly, online usage metrics have lacked transparency in how they filter non-human online activity. BitViews is a novel solution which uses blockchain technology to bypass both problems: online AMS usage will be recorded on a public, distributed ledger, obviating the need for a central responsible agency, and the rules governing activity-filtering will be part of the open-source BitViews blockchain application, creating complete transparency. Once online AMS usage has measurable value, researchers will be incentivized to promote and disseminate AMs. This will fundamentally reorient the academic publishing ecosystem. A key feature of BitViews is that its success (or failure) is wholly and exclusively in the hands of the worldwide community of university and research libraries, as we suggest that it ought to be financed by conditional crowdfunding, whereby the actual financial commitment of each contributing library depends on the total amount raised. If the financing target is not reached, then all contributions are returned in full and if the target is over-fulfilled, then the surplus is returned pro rata.
