Benefits of Open Access to Data

The report "Costs and Benefits of Data Provision" (by John Houghton, September 2011) has been released. This is a 66 page (1.6Mbyte PDF) document, sponsored by the Australian National Data Service (ANDS). In one case, for the Australian Bureau of Statistics, the benefit of open access are estimated to be at least five times the cost.

As the reports was released in PDF, it is difficult to read on-line. Here is the table of contents and Summary of findings, converted to web format (diagrams omitted):

Summary of findings

Over the last decade there has been increasing awareness of the potential benefits of more open access to Public Sector Information (PSI) and the findings of publicly funded research. That awareness is based on economic principles and evidence, and it finds expression in policy at institutional, national and international levels.

Public Sector Information (PSI) policies seek to optimise innovation by making data available for use and re-use with minimal barriers in the form of cost or inconvenience. They place three responsibilities on publicly funded agencies: (i) to arrange stewardship and curation of their data; (ii) to make their data readily discoverable and available for use and re-use with minimal restrictions; and (iii) to forgo fees wherever practical.

This report presents case studies exploring the costs and benefits that PSI producing agencies and their users experience in making information freely available, and preliminary estimates of the wider economic impacts of open access to PSI. In doing so, it outlines a possibly method for cost-benefit analysis at the agency level and explores the data requirements for such an analysis – recognising that few agencies will have all of the data required.

There are many ways in which the provision of more open access to PSI can impact upon the costs faced by the government agency producers and the many existing and potential users of the information. This study focuses on three main elements:

  • The costs and cost savings experienced by PSI producing agencies involved in the provision of free and open access to information;
  • The costs and cost savings experienced by the users of PSI in accessing, using and re- using the information; and
  • The potential wider economic and social impacts of freely accessible PSI.
It is always more difficult to identify benefits than costs. Benefits may accrue in a variety of ways, including cost savings, efficiency gains, and new opportunities to create value through doing things in new ways and doing new things. These are, successively, more difficult to quantify: not least because they often emerge over time and can only be realised in the future.

An obvious approach is to begin with the most direct and directly measurable benefits, namely agency and user cost savings. Wider benefits are more difficult, and in some cases impossible, to measure. In this study, we explore impacts on consumer welfare and attempt to estimate the impacts of increased access and use, as measured by increased downloads, on returns to expenditure on data production.

While there are some one-off costs involved in the change to open access, most are recurring annual costs (e.g. agency IT and hosting costs, revenues foregone, etc.). Hence, both the agency and user costs that are modelled are annual costs, and the cost savings annual savings. In terms of the wider benefits of open access to PSI, returns to investment in data production are recurring annual returns, lagged and discounted over the useful life of the data – using a perpetual inventory method. Consequently, the cost-benefit comparisons presented in this study include annual agency and user costs and cost savings as well as the wider benefits arising from increased returns to annual expenditure on data production (Figure 1). They compare the costs and benefits at the time of the transition to open access (i.e. at the prices and levels of activity of
the time).

It is clear from the case studies presented that even the subset of benefits that can be measured outweigh the costs of making PSI more freely and openly available. It is also clear that it is not simply about access prices, but also about the transaction costs involved. Standardised and unrestrictive licensing, such as Creative Commons, and data standards are crucial in enabling access that is truly open (i.e. free, immediate and unrestricted).

For example, we find that the net cost to the Australian Bureau of Statistics (ABS) of making publications and statistics freely available online and adopting Creative Commons licensing was likely to have been around $3.5 million per annum at 2005-06 prices and levels of activity, but the immediate cost savings for users were likely to have been around $5 million per annum. The
wider impacts in terms of additional use and uses bring substantial additional returns, with our estimates suggesting overall costs associated with free online access to ABS publications and data online and unrestrictive standard licensing of around $4.6 million per annum and measurable annualised benefits of perhaps $25 million (i.e. more than five times the costs).

While data are more limited, there appears to have been an even more compelling case for making fundamental geospatial data freely available. Of course, the relative cost-benefits apply to the form of PSI involved and do not reflect in any way on the performance of the producing agencies. Some forms of PSI underpin major industries and contribute to their growth and prosperity. Other forms of PSI may have an important influence on policy decisions, but the economic impacts may be more limited and difficult to trace.

The publications and data arising from publicly funded research differ somewhat from other forms of PSI. Consequently, it is difficult to draw direct lessons for the research sector from the case studies explored in this report. Nevertheless, it is clear that many of the same issues arise when attempting to measure the value of the information and/or the costs and benefits associated with providing open access to it.

The evidence from previous studies suggests that individual cases vary greatly, making generalisation extremely difficult. Perhaps, what could more usefully be generalised are the methods of analysis. For example, it would be useful to combine the frameworks and models into a tool that could be applied in assessing the costs and benefits of research data curation and sharing, and to further develop the framework for estimating cost-benefits outlined in this study to produce a tool tailored to the analysis of the costs and benefits of providing open access to PSI. These tools might consist of a template for data collection, a draft questionnaire outlining the questions needed to elicit the necessary information, and a simple spreadsheet-based online model that people could use to perform a cost-benefit analysis. The models should include all possible quantifiable costs and benefits, but must also include qualitative issues to help to prioritise data preservation, access and curation projects (e.g. incorporate a balanced scorecard approach to weighing the more intangible benefits).

What this study demonstrates is that the direct and measurable benefits of making PSI available freely and without restrictions on use typically outweigh the costs. When one adds the longer-term benefits that we cannot fully measure, and may not even foresee, the case for open access appears to be strong. ...
