Based on our brief review of the literature on water governance, we argue for a second-generation research agenda, one that pays more attention to the study of incentive structures, is multi and inter-disciplinary in orientation and with clear policy implications. In this section, we illustrate how theories drawn from public economics, new institutional economics, political economy and public administration can help diagnose incentive issues associated with water governance. We argue that these analytical tools can help complement the approaches proposed by Saleth and Dinar (
2005) and Biswas and Tortajada (
2010) to advance the study of water governance.
3.1 Public Economics
Public economics is primarily concerned with how public policies affect social welfare. Its core diagnostic tool is the idea of market failures, which occurs when reliance on a free market leads to inefficient social outcomes. In this section, we explore the concept of market failures as it applies to water governance, in particular the concepts of externalities, missing or non-functioning markets, public goods/common pool resources.
Rogers and Hall (
2003) catalogued several implications of market failures in the water sector. For instance, upstream-downstream externalities in river basins can lead to environmental, economic, and social externalities, which provide economic justification for government intervention. This problem of externalities has provided the theoretical foundation for integrated river basin management as a mode of governance. In practice, they are important reasons resulting in the concept of integrated river basin management remained problematic that the political and administrative transaction costs in large river basins are high and capacities of governments in developing countries remain weak. Second, non-priced assets and missing markets, or some aspect of water services such as flood control, are not priced which can lead to their sub-optimal provision and production. Missing water markets has provided the theoretical basis for proposals to facilitate or simulate the functioning of water markets through assignment or auction of water rights. Water markets are already functioning in Southwest United States (Brewer et al.
2008; Brown
2006; Brookshire et al.
2004) and Australia (Brooks and Harris
2008; Harris
2011). However, in some developing countries, prohibitive transaction costs and weak institutional frameworks (i.e. unclear water rights and weak enforcement mechanisms) make water trading in these countries more challenging (Wang et al.
2008).
Third, flood control and water quality protection can often be public goods while most water investments involve economies-of-scale making them natural monopolies. Economies of scale has provided the theoretical foundation for the continuing central role of the government in making investments in the water sector and has implications in the design of risk allocation mechanisms for public-private partnerships in water.
Finally, ignorance and uncertainty about water hydrology makes it difficult for markets to set prices correctly and therefore fail to adequately provide for socially optimal levels of these goods. All of these provide an economic rationale for governments to play a central role in water governance but problems of government failure—which we discuss below—compounds the problem.
We agree with Rogers and Hall (
2003) that many, if not most, of water governance issues arise from the characteristics of water resources and water services mentioned above. In addition, we argue that the theoretical and practical implications of these market failures for our understanding of water governance remain underdeveloped. We illustrate this with three examples. First, externalities in river basin governance such as cross-boundary and inter-sector water management, are often cited as a justification for pursuing river basin organizations and integrated water resource management (IWRM).
Biswas (
2004), however, has argued that while the concept of IWRM looks attractive, a deeper analysis brings out many problems, both in concept and implementation, especially for meso to macro-scale projects. The definition of IWRM, he argues, continues to be amorphous, and there is no agreement on fundamental issues like what aspects should be integrated, how, by whom, or even if such integration in a wider sense is possible. We agree with this critique and add that debates on the value of IWRM are academic unless it can be compared to the next best institutional alternative. Absent this comparison, it is unproductive to pass judgment on one institutional solution without reference to the next best alternative.
Despite these valid criticisms, IWRM remains a popular and widely used concept in water management around the world in both developed and developing economies (e.g. Chikozho
2008; Timmerman et al.
2008; Ako et al.
2010). In fact, the apparently successful case of managing one of the world’s largest river basins—the Yellow River Basin in China with an area of 752,000 square kilometers – is now being offered as an argument that IWRM is possible even for such a scale. In this case, the Yellow River Conservancy Commission, authorized by the central government, implemented water allocation regulations to prevent the cutoff of continuous flow in the lower Yellow River since 1990s (Wang and Ching
2013).
Second, it is commonly argued that water services should be subsidized and kept in the control of government for several reasons: water is essential to life, water supply has natural monopoly characteristics and because it is a critical infrastructure. As a critical infrastructure, water supply requires tight coordination of its core transactions in order to maintain technical integrity as well as economic coherence in the system (Menard
2008).
For these reasons, governments worldwide continue to regulate its price, quality and standards of service. Indeed, at least 85 % of water utilities worldwide are under the control of governments but it is also the case that most of these utilities are often poorly performing. This leads to an important question that has not been adequately resolved: how can the governance of public water utilities be improved to make them more efficient, responsive and sustainable? Many studies (e.g. Rogers and Hall
2003; Weimer and Vining
2005; Araral
2008) suggest that a key solution is to give them autonomous status but the political economy of water makes this more difficult in practice.
Third, water trading has been proposed as a key solution to the problem of water scarcity. However, the prohibitive costs of water trading and unclear water rights has led to governments taking a more active role in facilitating the emergence of quasi water markets—through legal infrastructure and the assignment of water rights which would otherwise fail in a market setting. Examples of these include water markets in Chile (Bauer
2004) and more recently in China (Wang
2012). However, in some developing countries with weak legal infrastructure, where water rights are unclear and enforcement is often weak or corrupted, water markets remain undeveloped and are less likely to succeed (Bjornlund and McKay
2002).
A related concept to direct water trading is the notion of virtual waters. Its central implication is that water-short countries could import water-intensive agricultural products from water-abundant countries, while using their limited domestic water resources for higher valued activities (Yang and Zehnder
2007; Abu-Sharar et al.
2012). This idea is an adaptation of the notion of comparative advantage in international trade. Critiques, however, suggest that while the idea is compelling and provides a helpful perspective, it is a misleading and insufficient policy criterion because it is not based on a theoretical framework and not consistent with the economic concept of comparative advantage (Wilchens
2010).
A similar idea is the notion of water footprints, a body of work associated with Hoekstra and Chapagain (
2007). The main idea—an adaptation of the notion of carbon footprints—is that while the river basin may be the appropriate unit of analysis for planning and institutional arrangements, this may not always be sufficient to deal with contemporary water issues. This is because many of today’s water issues have (sub) continental or even global dimension, which demands a governance approach that comprises coordination and institutional arrangements at a level above that of the river basin.
For Hoekstra (
2009), several developments have converged to provide the rationale for the water footprint approach. First, local issues of water scarcity and flooding, he argues will be enhanced or weakened by human-induced global climate change. Second, local problems of water pollution are often intrinsic to the structure of the global economy. Third, there is a growing presence of multinationals in the drinking water sector. Fourth, several national governments are developing plans for large-scale inter-basin water transfers. Fifth, an increasing number of water-short countries seek to preserve their domestic water resources through the import of water in virtual form. Sixth, global trade in water-intensive commodities offers the opportunity of global water saving if this trade is from countries with high to countries with low water productivity.
Hoekstra’s rationale for the water footprint approach is well argued if not compelling (Hoekstra
2009). However, as a research agenda it is yet to take off in terms of scholarly work and policy application. As it is, the program falls short of explaining why the use of water footprints can be a viable alternative given their contractual and transaction cost implications, especially the problem of allocating those rights. It is yet to be established whether the associated transaction costs of creating the global infrastructure for such trade is actually worth the perceived benefits of adopting the approach compared to second best alternatives. The politics of water footprints is also not understood if indeed politically feasible.
3.2 New Institutional Economics
The second pillar of water governance research, we argue, is grounded in new institutional economics. In fact, much of the analytics of good governance has its origins from the work of new institutional economists such as North (
1990) on institutions in general, Williamson (
2002) on transaction cost, Coase (
1960) on property rights as well as mechanism design theorists such as Maskin and Tirole (
2004), among others. Here, we only review some of the theoretical core of new institutional economics such as the theory of incomplete contracts and transaction cost, agency theory, theory of property rights and the commons, and non-cooperative game theory. For readers interested in the broader literature, see the Handbook of New Institutional Economics edited by Shirley and Menard (
2005).
The theory of incomplete contracts has several important implications for water governance 2.0. For instance, the theory suggest that 1) inefficient outcomes in water supply can be understood as a function of incomplete contracts; 2) that contracts cannot be fully specified (i.e. obligations of both parties are not fully specified for all possible situations in the real world); and 3) if a contract can be renegotiated, it can be made more complete in the future assuming that a modicum of rule of law exists in that context to allow for credible contracting.
Similarly, the theory of transaction cost—or the cost of exchange—applied to water governance, suggests that 1) complete specification of water rights and contract enforcement is problematic; 2) opportunism by contracting parties is inherent; 3) that there is no optimal water governance structure (markets, hierarchies, franchises, cooperatives) but instead parties should settle for a remediable solution, i.e. second best solution with net benefits.
In practice, the theory of incomplete contracts and transaction cost can be used to help diagnose and possibly resolve a variety of important water governance issues. For instance, incomplete contracts and transaction costs can help explain the failure of privatization of water utilities (Araral
2009). Second, they can help explain why most water utilities remain controlled by governments despite their inefficiencies. Third, and more generally, Menard and Saussier (
2000) have demonstrated how contractual arrangements (or modes of governance) actually matter to the performance of urban water utilities.
Fourth, the theories of incomplete contracts and transaction cost can also explain why most concession contracts for water are often renegotiated and or returned to the government. For instance, most renegotiated or failed concession contracts in Latin America did not adequately account for a variety of risks such as political, commercial, financing and construction risks and as a result led to failures in the privatization of concession contracts. Consequently, the municipalization of urban water supply is now on the rise (Foster et al.
2003; Guasch
2004).
Fifth, these theories can likewise be extended to explain the difficulties of creating a market for water trading in developing countries where water rights are unclear and contract enforcement is weak or corrupted. They can also be used to understand the practical and contractual challenges of creating virtual water markets using water footprints.
Sixth, more recently, the concept of unbundling the water value chain (i.e. unbundling wholesale, distribution and retail), the concepts of competition for the market and competition in the market as well as the idea of output based water aid are some of the recent innovative implications coming from institutional economics that are currently being pilot tested.
In conclusion, in less than a decade, new institutional economics—with its focus on water rights, regulations, transaction cost and modes of governance—has shown its potentials as an analytic and prescriptive approach to advance the second-generation research agenda on water governance.
3.3 Political Economy
We refer to the third approach to water governance research as the political economy approach. This approach is concerned primarily about the interaction of the politics and economics—particularly the distributional aspects of water reform which has generally remained a black hole in the literature. Many prescriptions for improving water governance such as improving water rights, marginal cost pricing and privatization of utilities, among others—are naïve about the political dimensions of the problem which explains why there are very few successful water governance reforms. Indeed, water governance, to the extent that it involves conflict in the allocation and use of an increasingly scarce and valuable resource is an inherently political subject.
Perhaps the most significant empirically and theoretically grounded study on the political economy of urban water reform is that of Shirley (
2002). Based on a case study of six urban water reforms in Africa and Latin America, Shirley examined the politics, economics and micro institutional (regulatory, judicial, legal, political) determinants of successful and failed urban water supply reforms.
Clarke and Xu (
2004) likewise employ a political economy analysis to explain the determinants for successful water utilities privatization based on six case studies from Africa and Latin America. He argues that water sector reform must be politically desirable which is “more likely when the public operator is performing poorly and when government supporters benefit from reform—usually through improved quality, system expansion or reduced subsidies.” In addition, he argues that reform has to be politically feasible and suggest “if the government relies heavily upon groups that will lose from reform through price increases or job losses, reform will be unlikely.”
Another important study is that of Dinar (
2000) on the political economy of water pricing. Using theories of political economy and illustrated by case studies, Dinar emphasizes the link between property and pricing regimes, the power and influence between and within water resource management organizations, and shows the role of asymmetric information for the implementation of efficient pricing reform.
Konca (
2005) on the other hand provides an excellent treatment of the politics of transnational water governance using international relations theory. He argues that threats to the world's water commons have resisted the establishment of effective global or interstate water agreements through intergovernmental bargaining because the conditions for successful interstate cooperation—effective state authority, stable knowledge frameworks, and a territorialized understanding of nature—cannot be imposed upon water controversies. However, he argues, while interstate water diplomacy has faltered, less formalized institutions—socially and politically embedded rules, roles, and practices—have emerged to help shape water governance locally and globally. Along with Hoekstra’s water footprint approach, which has focused on the externalities of transnational water governance but has generally ignored its politics, Konca’s approach offers a potentially fruitful area of research for water governance 2.0.
In contrast, the theory of the commons and property rights along with the theory of collective action and non-cooperative game theory can be—and has been—used to explain a wide range of intractable problems in water resource management. These include problems of water pollution, unregulated ground water depletion as well as conflict and cooperation in river basin, watershed and irrigation.
These theories offer several policy relevant implications. First, conflicts among water users—between farmers, industries and states—are likely to arise when water is salient but scarce and where water rights are unclear and enforcement costs are prohibitive. Because the allocation of rights to a valuable and scarce resource is problematic and contested, a transparent, participatory and negotiated process of rights allocation is an efficient, equitable and sustainable solution.
Second, the theory of collective action in the commons as well as non-cooperative game theory has been the main theoretical basis for supporting or contesting the logic of integrated water resources management. The implications derived from the theory of contracts, property rights and transaction costs would support Biswas’ (
2004) critique of the problems of integrated water resources management (IWRM) at the same time offer a coherent diagnostic tool for why IWRM in practice is problematic.
In conclusion, political economy approaches to water governance offers implications for our understanding of the challenges of urban utilities reform, integrated water resources management, water rights and management of water conflicts, water tariffs and privatization of water utilities, among others.
3.4 Public Administration
The fourth pillar of water governance 2.0 is the public administration approach, which is concerned with the question why majority of water utilities and irrigation agencies in developing countries are inefficient. Its operational focus is on the organization and management determinants of the performance of water bureaucracies such as financial and personnel autonomy, human resource management practices such as compensation, leadership development, training, incentive structure, and problems generally associated with government failures.
The theoretical core of public administration problems in the water sector is rooted in a series of agency problems (Araral
2008). Agency problems arise because principals do not exactly have the same interests as their agents and because it is costly for the principals to monitor their agents. Agents have more information about their activities than their principals, which allows them to pursue their own interests to some extent. The principal then faces the task of creating organizational arrangements that minimize the sum of the costs of the undesirable behavior of agents and of the activity undertaken to control it.
While agency loss—the cost of inefficiencies and cost of remedying them—is universal in all organizations, several factors make them a more serious problem for public bureaus than private firms (Weimer and Vining
2005) and by implication, to public water utilities. These factors include difficulty of valuing outputs and performance and the lack of competition among public bureaus. The difficulty of valuing outputs and performance makes it difficult to determine the optimal sizes of public water bureaucracies and results into varying degrees of x-inefficiencies and allocative inefficiencies.
In addition, lack of competition gives public water agencies weaker incentives to innovate, as—unlike private firms—they are not driven out of existence for failure to do so. This lack of competition eventually leads to varying degrees of dynamic inefficiencies. What this suggests is that the variation in the performance of water utilities is a function of the ability to solve these various types of inefficiencies.
More generally, these inefficiencies can be attributed to a myriad of government failures, in addition to market failures. The theory of government failures is not as well developed as market failures but the central idea is that government interventions can often lead to inefficient outcomes. Rogers (
2002) cites the following examples of government failure in the water sector: corruption, price regulation, subsidies to resource users and polluters, inappropriate tax incentives and credits, over-regulation or under-regulation, bureaucratic obstacles or inertia, conflicting regulatory regimes, short-sightedness, voter ignorance and imperfect information.
Moreover, government failure is also closely associated with a myriad of problems: regulatory capture by special interest groups (water operators, industries, farmers lobbies, etc.), little incentives by bureaucrats for operational efficiency, imprecise reflection of consumer preferences (due to monopoly characteristics of urban water supply), inability of the government to control and regulate the sustainable use of water resource (due to fragmentation and information problems) and independence and impartiality of regulatory agencies (due to the political characteristics of water).
Only a few of this myriad of government failures have been studied for their implications to water governance. These include for example the effects of price regulation on the performance of water utilities (Araral
2008; Dinar
2000), bureaucratic obstacles, inertia or perverse incentives in water utilities (Araral
2010), irrigation agencies (Araral
2009) and the impact of regulating public utilities (Ehrhardt and Janson
2010).
Molle et al. (
2009)—based on a historical overview of the evolution, motivation and challenges faced by hydraulic (mainly irrigation) bureaucracies—argue that they have become an end by itself, “a symbol of state power and a fuel for rent seeking.” In the case of the Philippine irrigation bureaucracy, Araral (
2009) argues that the perverse incentive problems faced by irrigation bureaucrats were compounded by perverse incentives embedded in foreign aid overtime.
Araral (
2008) also studied the determinants of the performance of one of the best public water utilities in developing countries, the Phnom Penh Water Supply Authority (PPWSA) in Cambodia. Similarly, Tortajada (
2006) examined the determinants of performance of one of the best urban water supply agencies in the world, Singapore’s Public Utilities Board. Both papers conclude that corporate governance—autonomy of the utility, performance management and compensation, professional staff and progressive leadership, among others—are some of the key factors for their success. Ehrhardt and Janson (
2010) examined the effects of regulation on the performance of public water utilities and conclude that it is not useful in isolation because of the incentives embedded in the public sector.
Studies on corruption in the water sector in the last decade are few and are mostly descriptive or assertive, for example Plummer and Cross (
2007), Davis (
2004), and Zinnbauer and Dobson (
2008). The exceptions include Rinaudo (
2002) who provided a detailed account of corruption on irrigation in Pakistan, and Venot et al. (
2011) on water reservoirs in Ghana. As yet, there are no robust studies on the effects of corruption in the water sector.
In conclusion, the public administration approach to water governance—with its focus on agency problems and government failures in general—has important implications for improving the efficiency, effectiveness, responsiveness and sustainability of public water agencies especially in developing countries.
