Introduction
A knowledge economy has been described as one in which the generation and exploitation of knowledge has come to play the predominant part in the creation of wealth. It is not simply about pushing back the frontiers of knowledge; it is also about the more effective use and exploitation of all types of knowledge in all manner of economic activities (Department of Trade and Industry, 1998). Scholarly publishing plays a key role as it is central to the efficiency of research and to the dissemination of research findings, and the diffusion of scientific and technical knowledge. Recent advances in information and communication technologies are disrupting traditional publishing models, radically changing our capacity to reproduce, distribute, control and publish information. One key question is whether there are new opportunities and new models for scholarly publishing that might better serve researchers and more effectively communicate and disseminate research findings (OECD, 2005, p. 14).
Building on previous work, this paper looks at the costs and potential benefits of alternative models of scientific and scholarly publishing. The work began in Australia in 2006 with research that produced Research Communication Costs, Emerging Opportunities and Benefits (Houghton et al., 2006). This was followed by the Economic Implications of Alternative Scholarly Publishing Models for the Joint Information Systems Committee (JISC) in the United Kingdom (Houghton et al.,2009). This paper describes the approach used and summarises the findings of the latter study.
Alternative publishing models
The JISC study focused on three alternative models for scholarly publishing, namely: subscription publishing, open access publishing and self‐archiving.
- •
Subscription publishing refers primarily to academic journal publishing and includes individual subscriptions and the, so called, ‘Big Deal’ (where institutional subscribers pay for access to online aggregations of journal titles through consortial or site licensing arrangements). In a wider sense, however, subscription publishing includes any publishing business model that imposes reader access tolls and restrictions on use designed to maintain publisher control over access in order to enable the collection of those tolls.
- •
Open access publishing refers primarily to journal publishing where access is free of charge to readers, while authors and their employing or funding organisations pay for publication, or the publication is supported by other sponsors making it free for both readers and authors. Use restrictions can be minimal as no access toll is imposed.
- •
Open access self‐archiving refers to the situation where authors deposit their work in online, open access institutional or subject‐based repositories, making it freely available to anyone with Internet access. Again, use restrictions can be minimal.
Of itself, self‐archiving does not constitute formal publication so analysis focuses on two publishing models in which self‐archiving is supplemented by the peer review and production activities necessary for formal publishing, namely: (i) ‘Green OA’ self‐archiving operating in parallel with subscription publishing; and (ii) the ‘deconstructed’ or ‘overlay journals’ model in which self‐archiving provides the foundation for overlay journals and services (e.g. peer review, branding and quality control services) (Smith, 1999; Van de Sompel et al., 2004; Smith, 2005; Simboli, 2005; Houghton, 2005). Hence, each of the publishing models explored includes all of the key functions of scholarly publishing, including peer review and quality control.
Approach and methodology
The JISC project relied primarily on existing sources, collating activity cost information from the wide‐ranging literature on scholarly publishing [e.g. Tenopir and King (2000) and subsequent tracking studies; also Halliday and Oppenheim, 1999; Friedlander and Bessette, 2003; OECD, 2005; European Commission, 2006; Houghton et al., 2006; EPS et al., 2006; King, 2007; Björk, 2007; Clarke, 2007; CEPA, 2008]. Where necessary, these sources were supplemented by informal consultation with experts in the field.
Identifying costs and benefits
The first phase of the JISC study sought to identify all the dimensions of cost and benefit associated with each of the models, and examine which of the main players in the scholarly communication system would be affected, and how they would be affected by the adoption of alternative publishing models. In order to provide a solid foundation for analysis, we developed and extended the scholarly communication life‐cycle model, first outlined by Bo‐Christer Björk (2007).
Björk (2007) developed a formal model of the scholarly communication life‐cycle, based on the IDEF0 process modelling method often used in business process re‐engineering, to provide a detailed map of the scholarly publishing process. Björk’s central focus was the single publication (primarily the journal article), how it is written, edited, printed, distributed, archived, retrieved and read, and how eventually its reading may affect practice. Extending the model outlined by Björk, the scholarly communication process model developed for the JISC study included five core scholarly communication process activities:
- 1.
fund research and research communication;
- 2.
perform research and communicate the results;
- 3.
publish scientific and scholarly works;
- 4.
facilitate dissemination, retrieval and preservation; and
- 5.
study publications and apply the knowledge (Figure 1).
Each of these is further subdivided into a detailed description of the activities, inputs, outputs, controls and supporting mechanisms involved (Erraguntla and Benjamin, 2007). This formal process modelling was used to identify activities and provide the foundation for activity costing.1
There are various ways to explore the impacts and possible benefits of alternative publishing models. Focusing on access and use, Houghton et al. (2006) note that potential benefits include impacts relating to research use of the content, industry and government use, and use by the wider community. While providing a useful starting point, their analysis focuses on use impacts and does not explore production‐side impacts.
Key issues in open access are access and permission, where access includes accessibility in the sense of the ease and affordability of access, and permission refers to permission to use the material in terms of what is permitted, and the time and cost involved in checking and obtaining permission. This suggests an analysis along the overlapping dimensions of access and permission, mediated by cost in terms of both money and time – in essence, setting the alternative publishing models against the ‘ideal’ of open access for free, immediate and unrestricted access by exploring the time and cost involved in accessing and using scientific and scholarly works (Figure 2).

Drawing on a number of previous reviews and following an established lead, Martin and Tang (2007) explore seven mechanism or channels through which the benefits of publicly funded research might flow through to the economy and to society more generally:
- •
an increase in the stock of useful knowledge;
- •
the supply of skilled graduates and researchers;
- •
the creation of new scientific instrumentation and methodologies;
- •
the development of networks and stimulation of social interaction;
- •
the enhancement of problem solving capacity;
- •
the creation of new firms; and
- •
the provision of social knowledge.
While open access publishing models relate to research publications alone, enhanced access and reduced permissions barriers could be important in all of these (arguably, with the exception of the third). More open and less restricted access would effectively increase the stock of useful knowledge that is accessible to would‐be users; contribute through impacts on education to enhancing the supply and skills of researchers; enable the development of networks on the basis of access to a shared, common and complete set of information; enhance problem solving capacity by providing the necessary supporting information; enable the provision of a range of social knowledge (e.g. in health care); and provide opportunities for the emergence of new firms and new industries [as happened in the case of Weather Derivatives (Pluijmers and Weiss, 2005; Stell, 2005)].
Of course, the principal input to the process of performing research and communicating the results is existing knowledge, as the production of knowledge depends, in large part, on its consumption. Hence, costs and benefits on the production side also relate, in large part, to access and permission – the costs associated with limiting and managing access, copyright, licensing and permissions; and the cost savings (benefits) of not doing so. Indirect benefits also relate, in large part, to access and permission – the greater use, higher profile and higher impact/return for funders, researchers and research institutions, publishers and those facilitating dissemination, retrieval and preservation. Access and permission are crucial to the overall efficiency of the scholarly communication system.
Hence, our approach to exploring and quantifying costs, impacts and benefits is twofold. First, a detailed ‘bottom up’ costing that provides a foundation for the estimation of cost savings and the development of scenarios exploring impacts. Second, a ‘top down’ modelling of impacts of enhanced access on returns to research and development (R&D) through further development and application of the modified Solow–Swan model outlined by Houghton et al. (2006) and Houghton and Sheehan (2009).
Quantifying costs and benefits
The second phase of the JISC study sought to quantify the costs and benefits, identify possible implications for each of the main players in the scholarly communication system and, as far as possible, compare the costs and benefits of the three models. There are three elements to our approach to quantifying costs and benefits.
- •
First, we explored the costs of the process activities and then summed them to estimate system‐wide costs. From this we can see cost differences and direct savings.
- •
Second, we presented cases and scenarios to explore the potential cost savings resulting from alternative publishing models (e.g. looking at impacts on search and discovery, and library handling costs). From this we can explore indirect cost differences and savings.
- •
Third, we approached the issue from the top down and model the impact of changes in accessibility and efficiency on returns to R&D using a Solow–Swan model, into which we introduce accessibility and efficiency as negative or friction variables to reflect the fact that there are limits and barriers to access and to the efficiency of production and usefulness of knowledge (Houghton and Sheehan, 2009).
A full description of the modelling approach and details of its operationalisation can be found in Houghton et al. (2009).
Estimating activity and system costs
In the first of these steps, we produced detailed costings of activities with a focus on cost differences between the three publishing models. One key challenge is to separate the cost impacts of publishing models from those of publishing format, so that we can explore the cost differences between subscription and open access publishing models independent of differences between print and electronic production. Our approach was to estimate costs for print, dual‐mode (parallel print and electronic production) and electronic‐only formats for subscription and open access models, and then compare subscription and open access models as if they were all electronic or ‘e‐only’. All of the costings included commercial publisher margins.
For subscription publishing, we estimate an average publisher cost of around £3250 per article for dual‐mode production, £2730 per article for print‐only production, and £2335 per article for e‐only production (excluding the costs associated with external peer review and value added tax) (Figure 3).2
For open access publishing, we estimate average per article costs at £1525 for e‐only production. Excluding the costs of copy printing and delivery, we estimate the cost of dual‐mode open access publishing at around £2000 per article and print‐only open access publishing at £1830 per article.3
We included the implied publisher costs of overlay services to open access self‐archiving (the overlay services model), with the same commercial management, investment and profit margins applied. This suggested that operating peer review management, editing, production and proofing as an overlay service would cost around £1125 per article excluding hosting, or £1260 including hosting.
In the second of the three steps, we summed the per article costs of the three publishing models in electronic‐only format through the main phases of the scholarly communication life‐cycle.4 We found that for UK higher education, average subscription publishing system costs would amount to around £8295 per article (excluding VAT), average open access publishing costs would amount to £7485 per article, and average open access self‐archiving costs £7115 per article (including overlay review and production services with commercial margins). At these costs, open access publishing would be around £815 per article cheaper than subscription publishing, and open access self‐archiving with overlay services around £1180 per article cheaper (Figure 4). For UK higher education, these journal article cost differences would have amounted to direct savings of around £80 million per annum circa 2007 from a shift from subscription to open access publishing, and £116 million from a shift to open access self‐archiving with overlay services.
Estimating system savings
In addition to these cost differences there are potential system cost savings in such areas as library acquisition and handling, search, discovery access and research use, funding, reporting and evaluation. As many of the potential cost savings cannot be fully realised unless there is worldwide adoption of open access, we explored unilateral national and worldwide adoption scenarios. In the unilateral national open access scenario, funder, research, library handling and subscription cost savings are scaled to the UK’s article output (they are in proportion to the share of worldwide journal literature that would be open access as a result of the unilateral adoption of alternative open access models by the UK). In the ‘Green OA’ (open access self‐archiving without subscription cancellations) model, self‐archiving operates in parallel with subscription publishing, so there are no publisher, library handling or subscription cost savings.
We estimated that open access publishing for journal articles using the ‘author‐pays’ model might bring system savings of around £500 million per annum nationally in the UK in a worldwide open access system (at 2007 prices and levels of publishing activity), of which around £430 million would accrue in higher education. Open access self‐archiving without subscription cancellations (Green OA) might save around £108 million per annum nationally in a worldwide Green OA system, of which around £75 million would accrue in higher education. The open access self‐archiving with overlay services model explored is necessarily speculative, but would be likely to produce similar savings to open access publishing using the ‘author‐pays’ model.
These savings can be set against the costs. We estimated that with author fees of £1500 per article published, open access publishing all journal articles produced would have cost around £170 million nationally in 2007, of which £150 million would have been faced by the universities. The operation of a system of open access institutional repositories in which all institutions operated a single repository and publications were self‐archived once would have been likely to cost around £22 million nationally and £18 million for the universities.
Estimating the impact of more open access on returns to R&D
In the third of the three major steps, we modify a basic Solow–Swan model to estimate the impacts of changes in accessibility and efficiency on returns to R&D. The standard Solow–Swan approach makes a number of key simplifying assumptions, including that all R&D generates knowledge that is useful in economic or social terms (the efficiency of R&D), and that all knowledge is equally accessible to all entities that could make productive use of it (the accessibility of knowledge). Addressing these assumptions, we introduced accessibility and efficiency as negative or friction variables, to reflect the fact that there are limits and barriers to access and to the efficiency of production and usefulness of knowledge. Then we explored the impact on returns to R&D of reducing the friction by increasing accessibility and efficiency (Houghton and Sheehan, 2009; Houghton et al., 2009).
We produced range estimates, looking at rates of return to R&D from 20% to 60% (Geuna and Arundel, 2003) and increases in access and efficiency of 1% to 10%. For the purposes of discussion, based on an extensive review of the literature, we took the lower bound average 20% social return on public sector R&D and suggested that a 5% increase in accessibility and efficiency might be plausible. Despite limitations in models of this type, these model parameters are grounded and, if anything, may err on the conservative side. For example, the percentage change in accessibility and efficiency is based on metrics relating to: the share of publications in general and journals in particular in the research stock of knowledge; the share of the research stock of knowledge potentially available to open access; a number of proxy measures of accessibility, including UK research library subscriptions and conservative estimates of the open access citation advantage; and a number of estimates of the potential efficiency implications of access limitations, such as duplicative research, and of relaxing these limitations; for example, by speeding up the research and discovery process and facilitating greater collaboration (Houghton et al., 2009).
Comparing costs and benefits
First, we explored the benefit/cost implications of simply adding open access publishing and self‐archiving to current activities, all other things remaining the same (ceteris paribus scenarios). Then we explored the implications of open access publishing and self‐archiving as alternatives to current activities, by adding the estimated system savings to the estimated increases in returns (net cost scenarios).5 These benefit/cost comparisons suggest that the additional returns to R&D resulting from enhanced accessibility and efficiency alone would be sufficient to cover the costs of parallel open access self‐archiving without subscription cancellations (Green OA). When estimated savings are added to generate net costs, there is a substantial increase in the benefit/cost ratios, and for both open access publishing (‘Gold OA’) and self‐archiving alternatives, the benefits exceed the costs, even in a transitional period. Indicative modelling of post‐transition ‘steady‐state’ alternative systems suggests that, once established, alternative open access publishing and/or self‐archiving systems would produce substantially greater net benefits.
For example, during a transitional period of 20 years, we estimated that, in an open access world:
- •
the combined cost savings and benefits from increased returns to R&D resulting from open access publishing all journal articles produced in the UK’s universities using an ‘author‐pays’ system would be around three times the costs;
- •
the combined cost savings and benefits from open access self‐archiving in parallel with subscription publishing would be around seven times the costs; and
- •
the combined cost savings and benefits from an alternative open access self‐archiving system with overlay production and review services would be around four times the costs (Table 1).

Conclusions
The analysis summarised in this paper compares scholarly publishing models as if they were alternatives. In reality, of course, there are variations and hybrids (e.g. delayed open access, and open choice/author choice) and the models co‐exist in various mixes in different fields of research. Nevertheless, the models do have some key defining characteristics, and these characteristics have cost implications for producers, intermediaries and the users and consumers of scientific and scholarly journal content. They also have implications for the efficiency of research, the accessibility of research findings and its impacts, and, thereby, for returns to investment in R&D.
Our preliminary analysis of the potential benefits of more open access to research findings suggests that more open access would have substantial net benefits in the longer term, and while net benefits may be lower during a transitional period, they are likely to be positive for both open access publishing and self‐archiving alternatives (Gold OA) and for parallel subscription publishing and self‐archiving (Green OA).
Reactions to the report
Initial responses to the JISC report of Houghton et al. (2009) were polarised. Whilst many academics and funders welcomed the report, some individual scholarly publishers and their trade associations reacted negatively. However, many of their criticisms were aired in press releases, e‐mails and electronic newsletters rather than in traditional scholarly fora.
Ware and Mabe (2009, p. 56) summarised the criticisms, noting that:
[The Houghton Report] underestimated the efficiencies of the current subscription system and the levels of access enjoyed by UK researchers. Many of the savings hypothesized would depend on the rest of the world adopting author‐pays or self‐archiving models. The calculated savings would remain hypothetical unless translated into job losses … Critics also argue that Houghton et al. underestimated the costs of switching to an author‐pays model because they underestimated the true costs of publishing an article only, and because additional costs such as the infrastructure required to manage the many small publication charges were not included.
While referring to critics, Ware and Mabe (2009) fail to cite a single publication. This reflects the fact that criticisms have not appeared in traditional media, and are therefore difficult to address seriously. Nevertheless, JISC (2009) released a response addressing the criticisms soon after the release of the report.
The claim ‘… because additional costs such as the infrastructure required to manage the many small publication charges were not included’ is oft‐repeated, but is not correct, as a cost for author‐side payments was included in the model. There were two considerations in estimating the costs involved in such transactions: evidence of relevant transaction costs, and the number of transactions involved. First, most of the major publishers offer pay‐per‐view for articles at around US$30, suggesting that they can make transactions and some content revenue at US$30 per transaction with people from all over the world with whom they have no pre‐existing business relationship. Secondly, publishers typically deal with the ‘corresponding’ or lead author of each paper, thus limiting transactions to one per published paper. The average number of papers per journal title per year (with large variation) is said to be of the order of 120, and while the average number of subscribers is less certain, a subscription journal that had fewer subscribers than papers in any given year would probably be in financial difficulty. Hence, the ‘client’ transaction costs of an author‐pays journal are likely to be lower than those of a subscription journal, and the evidence from pay‐per‐view costs suggests that publishers’ author‐fee transaction costs might be of the order of US$30 per paper published.
In short, the criticisms fall into two broad groups. The first is that certain costs have not been taken into account in the model; the second is that some of the figures in the model are incorrect. If the publishers are confident about these criticisms, the way to deal with the matter is through normal scholarly discourse. Publishers should develop their own model and/or use the Houghton model with their own figures, to see how the figures pan out. But they would have to do this in a scholarly publication, so that others can read about their methodology and learn what data were input. Unsubstantiated anonymous sniping at a report does not contribute to constructive dialogue; the correct way is for publishers to publish their assumptions and results in an open and transparent manner so that scholars and other stakeholders can make informed assessment.
