Many policymakers are unwilling, or think that it is infeasible, to perform comprehensive cost-benefit analysis (CBA) of programmes in social policy arenas. What principles actually underlie CBA? An understanding is necessary to assess whether other evaluation methods are close enough to CBA to provide useful information on social efficiency. This paper explains five underlying CBA principles and the challenges in applying them to social policy arenas. It assesses a number of 'less-than comprehensive' versions of CBA and analyses their 'closeness' to comprehensive CBA and, thus, their value as assessments of changes in social efficiency. We show some types of analysis are not close enough and explain why. We provide a taxonomy of these methods in terms of their comprehensiveness with respect to both social costs and benefits. We also argue that an analysis should provide a clear normative basis for its geographic scope in order to claim it assesses economic efficiency.

There is very limited theory and policy guidance that specifically relates to multijurisdictional and multimodal (M&;M) infrastructure corridors: those that traverse national boundaries and encompass multiple modes of co-located infrastructure modes. This paper develops a framework for understanding the social welfare costs and benefits—and the barriers to implementing—these corridors. The framework posits the need for both a dedicated assembler and a national (or supranational) sponsor. An assembler provides the platform to match up initial property rights holders, infrastructure mode providers and end users. The sponsor financially and politically backstops an assembler. We decompose the economic necessity for, and advantages of, an assembler and also those that result from some degree of multimodality. We also consider the economic and political barriers to M&;M corridor implementation. To illustrate these, we review the evidence from the very small number of proposed or realised M&;M corridors and closely related projects. Although reliable evidence is scarce, it is consistent with the framework’s implications regarding the need for both an assembler and a sponsor.

Whose costs and benefits should count in cost-benefit analysis (CBA)? This is an important practical question requiring answers for analysts because most government agencies offer only permissive or vague guidance. Drawing primarily on foundational CBA principles, we present a conceptual framework for specifying standing to answer three important boundary questions: Where? Who? What? First, a standing framework requires a definition of jurisdictional boundaries (the "where" question), whether national, subnational, or supranational. Second, a framework should be clear about which persons within the jurisdiction have standing (the "who" question). For example, should undocumented residents have standing? Third, the framework requires clarity on the standing of certain individual preferences (the "what" question), such as for harmfully addictive private or public goods that express "moral sentiments," or when choices do not maximize the value of consumption. We seek to provide guidance for CBA practice within this framework.

This article presents new estimates of social discount rates (SDRs) for seventeen Latin American countries for use in public project evaluation. We derive the SDRs based on the social rate of time preference method and provide the required parameter values. These rates range from 2.14 percent for Paraguay to 5.83 percent for Chile. The unweighted average recommended rate is 3.77 percent, which is close to the rates mandated by most European countries. We also review current governments’ SDR practices worldwide, including Latin America, and find that the proposed country-specific SDRs are significantly lower and less dispersed across countries than the rates most Latin American countries currently recommend. Using four archetypal projects profiles, we show the potential impact on the net present values of varying important parameters, including growth rates.

The Canadian Northern Corridor (CNC) is a proposed multimodal, multijurisdictional corridor. It is a highly complex, long-term infrastructure project. Such projects often fail to get implemented, but the limited evidence suggests that they can get built when a single entity (a national government or a supranational organization) assembles the rights of way and provides corridor access to various infrastructure providers. This entity, which we refer to as the “assembler,” has to (1) assemble the required rights of way from all those currently holding the property rights; and (2) decide on the allocation of, at least, usage property rights to different kinds of infrastructure providers (and ultimately users of that infrastructure). For the CNC, the assembler could be the federal government or a consortium that also includes subnational levels of government. Because First Nations and other Indigenous groups in Canada have constitutional (or at least quasi-constitutional) status, they might also have a role in a consortium.

Large amounts of e-waste are processed “informally” in lower income countries. Such processing releases dangerous pollutants, which increase mortality and reduce cognitive functioning. This paper estimates the social cost of informal e-waste processing in Southern China. This parameter may be “plugged-in” to cost-benefit analyses that evaluate the economic efficiency of policies to reduce informal e-waste processing in China or other lower income countries. It may also be used in the estimation of the social benefits (or costs) of new or proposed e-waste processing policies in higher income countries. We estimate that the social cost of informal e-waste processing in Guiyu is about $529 million. This amount is equivalent to about $423 per tonne (in 2018 US dollars) or $3528 per person, which is over half the gross income per capita of the residents of Guiyu. We also perform sensitivity analysis that varies the estimated mortality outcomes, the value of a statistical life and the amount of e-waste processed.

Some issues in the application of benefit–cost analysis (BCA) remain contentious. Although a strong conceptual case can be made for taking account of the marginal excess tax burden (METB) in conducting BCAs, it is usually excluded. Although a strong conceptual case can be made that BCA should not include distributional values, some analysts continue to advocate doing so. We discuss the cases for inclusion of the METB and the exclusion of distributional weights from what we refer to as “core” BCA, which we argue should be preserved as a protocol for assessing allocative efficiency. These issues are topical because a recent article in this journal recommends ignoring the METB on the grounds that desirable distributional effects offset its cost. We challenge the logic of this article and explain why it may encourage inefficient policies.

Governments in many industrialized nations have made concerted efforts to reduce their immediate expenditures and to reduce the cost of major infrastructure projects. Public–private partnerships (P3s) are one emerging method that might do so. Despite the increased use of P3s, there is little independent research on the effectiveness of P3s as a public policy instrument. This article considers the major rationales for P3s, including cost savings and keeping project financing off government budgets. It then presents a transaction cost model that suggests that P3s can often be prone to conflict, high contracting costs, opportunism and failure. Evidence from six major infrastructure projects and a summary analysis of US prisons is then presented. These cases confirm that contracting costs have been high, as predicted by the model. Specifically, high contracting costs reflect the presence of complexity/uncertainty, asset specificity, the potential for ex post bilateral opportunism and a lack of contract management skills by governments. Given these circumstances, the private sector can behave opportunistically at the expense of the public sector as there has sometimes been a political imperative to prevent projects from terminating. Public partners have also behaved opportunistically after projects are in place. Unless public sector managers recognize that they must design contracts that both compensate private sector partners for risk and then ensure that they actually bear it, P3s have little chance of being efficient or effective service delivery mechanisms.

Local governments typically provide a variety of services including roads, primary and secondary education, bus and other public transportation services, fire prevention, garbage collection, parks, policing, social assistance, and water and wastewater treatment. Many of these services require physical facilities in order to operate. Much public infrastructure is old and needs to be replaced. In many regions, the capacity of the infrastructure needs to be expanded. The cost of providing new or refurbished infrastructure continues to increase and, at the same time, many voters oppose tax increases. In attempts to do more for less, local governments have explored alternative forms of service delivery. Many services have been contracted out to the private sector, most notably for garbage collection but also in other areas. More recently, local governments have formed hybrid organisations to provide local services. This chapter focuses on hybrid organisations in which a local government and the private sector are partners in the sense that each sector has property rights pertaining to the organisation. We refer to these organisations as local government mixed enterprises (local MEs).

This paper analyzes the trade-offs between the social cost of risk bearing and incentive effects for technical efficiency in PPP contracts for utilities. Using a principal-agent perspective and assuming the government principal maximizes social welfare, the government should be risk neutral. It is inefficient for PPP agents to provide financing. Design/build offers the greatest potential PPP gains, but not necessarily more than fixed-price contracts. There may also be efficiency benefits during the operations phase. But, if agents have little control over revenues, then PPP operation creates substantial risk-bearing costs for agents.
