چکیده انگلیسی

In an earlier article in this journal (Grimsey, D., & Lewis, M. K. (2002b). Accounting for Public Private Partnerships. Accounting Forum, 26(3), 245–270), we examined the intricacies of the accounting issues raised by Public Private Partnerships (PPPs). It was argued that the critical accounting question from the public sector's viewpoint is not one of whether the arrangement is on or off balance sheet, but whether it represents good value for money. However, determining value for money for a PPP is an area in which, despite strong criticisms by a number of academic writers of the methods used by practitioners to evaluate value for money, surprisingly little engagement has taken place between the practitioners and the academics on the issues involved. This paper attempts to provide such an engagement. At the same time, because many of the academic critiques focus on the situation in one country (particularly the UK or Australia), we try to put matters into a broader, comparative context by considering approaches to value for money tests in a number of countries. Our examination is thus comparative in the sense of considering value for money tests in different countries, while also comparing the views of academics and practitioners.

نتیجه گیری انگلیسی

This paper has had two aims. At one level it has endeavoured to provide an overview, based on over twenty countries, of value for money assessment in Public Private Partnerships focusing in particular on the role played by the Public Sector Comparator. PPPs are well-established practice in the UK, Australia, The Netherlands, South Africa, Canada and Japan, and in all these countries PSCs are regarded as valuable for assessing value for money in procurement and evaluating and quantifying risk. However, the use of a PSC is not universal and elsewhere, where PPPs are employed, our survey reveals that other methods are employed. Overall, we find that there are four alternative approaches to evaluating value for money, although a number of countries that have used cost-benefit analysis or other techniques are now investigating the use of PSCs for ascertaining whether PPPs constitute good value for money. At a second level, the paper has sought to engage some of the academics voicing concerns about PPPs, examining some of the similarities and differences between their views and those of practitioners active in the market. Amongst some academics, the value for money tests involving PPP–PSC comparisons are criticized for the seeming arbitrariness of the assumptions underlying the PSC, especially with respect to risk transfer and the discount rate (where small changes can have a big impact on project choice), as well as for downplaying uncertainty and over-emphasizing financial factors relative to issues of long-term service delivery. Some of these matters (e.g., the assumptions underlining the PSC and risk transfer) have been considered by practitioners, who use statistical techniques such as sensitivity analysis and Monte Carlo methods to examine the robustness of the estimates. Other matters raised (e.g., the treatment of risk and the discount rate methodology) have, to a considerable degree, been overtaken by developments in policy analysis in both the UK and Australia, although aspects of the application of the new methodology remained unresolved. Uncertainty and the need to manage long-term service delivery are issues that remain on the policy agenda, although practitioner views on these matters have taken some different directions to the academic literature. Rather than go over some of the same ground, we would like to conclude with some general points. First, our survey shows not only that there are alternatives to the PSC approach but that there are many complexities and ambiguities involved in it which suggest that the calculation of the PSC needs to be seen merely as one factor, albeit significant, in procurement decisions. Its development constitutes a valuable discipline upon public sector procurement in assisting decision-makers to understand the project, the risks involved and how to deal with them contractually. In this respect, the risk analysis required for the PSC can be seen as part of the broader process of risk identification, allocation and management within the project. In many cases, the difference between the PSC and the private sector proposal will be relatively narrow and the procurer has to make professional judgements as to the value for money to be derived from contracting with the private sector and the risks which that route involves, while not ignoring that there are also large risks in the public procurement route, as indicated by the ‘optimism bias’ documented earlier. Second, the value for money test frequently comes down to a simple, single point comparison between two procurement options. In our view, the problem is that value for money is more often than not poorly understood and often equated with lowest cost. Such an approach fundamentally understates value in the context of achieving a project's objectives and protecting the government from adverse outcomes. Value is a complex trade off between cost, risk and performance, and in this framework it is important fully to understand the government's exposure to risk, defined as volatility of outcomes. Probability analysis overcomes the limitations of the simple point estimate value for money approach by specifying a probability distribution for each risk, and then considering the effects of the risks in combination. Nevertheless, it is important to remember that uncertainty is not the same as risk, and that consideration needs to be given to the unexpected as well as to measurable risks. Also, value for money as measured by financial comparisons should be augmented by a consideration of the policy and strategy context and the wider socio-economic costs and benefits, and we have no quarrel with the academic critics on that general point. This is one advantage of the approach where there is a full cost-benefit economic analysis of the feasible public sector option and the PPP route to procurement, but this alternative does come at a considerable cost in terms of a commitment of time and resources that the more practically oriented PSC approach to some degree obviates. Third, PPPs are not, and probably never will be, the dominant method of infrastructure acquisition. They are too complex, and costly, for many small projects. In some cases, they may be beyond the capacity of the public sector agency to implement and manage. For other projects the tight specification of the outputs required may be difficult to detail for an extended period. In other cases, a sound business rationale may not exist. Nonetheless, for those projects that are suitable, they are a way of introducing very different incentives into the procurement process. These incentives, we argue, are distinctive to PPPs relative to other procurement approaches and come about as a result of the fusion of the upfront engineering of the design and the finance with the downstream management of construction and service delivery. Private risk finance using a mix of equity and debt is central to this process, and provides the ‘glue’ that holds together the transaction and the risk allocation amongst the various parties. Moreover, there is evidence that the private sector does respond to these signals and gets it right more often than not. About 75 percent of major infrastructure projects in the UK were late and over budget before PPPs came into play. Under PPP/PFI arrangements, 75 percent of projects are on time and to budget.
