Abstract
The purpose of this paper is to provide an overview of the literature on the political economy of policy instrument choice and relate it to the experiences in agriculture. The paper is therefore organized as follows. The second section provides a ranking of policies as to their transfer efficiency and determines the standard of evaluation, given that no policy is perfect in achieving its goals. The third section explores why political competition does not ensure that an efficient policy instrument is chosen. The following two sections explain the two key theories: enforcement and commitment problems in section four, and information and agency problems in section five. Section six presents the important Grossman-Helpman model of inefficient policy choice that falls outside these two general theories. Section seven describes how policy instrument choice in agriculture is often a discrete outcome in response to a crisis and therefore becomes path dependent, resulting in a status quo bias. Section eight describes how trade agreements can affect policy instrument choice. The final section gives some guidance as to the outstanding issues.

Publication Political Economy of Distortions to Agricultural Incentives(World Bank, Washington, DC, 2009-05)During the 1960s and 1970s most developing countries imposed anti-agricultural policies, while many high-income countries restricted agricultural imports and subsidized their farmers. Both sets of policies inhibited economic growth and poverty alleviation in developing countries, while doing little to assist small farmers in high-income countries. Since the 1980s, however, many developing countries began to reduce the anti-agricultural bias of sectoral policies, and from the early 1990s the European Union began to move away from price supports to more-direct forms of farm income payments. This paper summarizes a forthcoming book that seeks to explain this evolving pattern of distortions to incentives conceptually and econometrically by making use of new political economy theory and a new globally comprehensive and consistent set of estimates of the changing extent of annual distortions over the past half-century. The distortion estimates involve more than 70 products that cover around 70 percent of the value of agricultural output in each of 75 countries that together account for over 90 percent of the global economy, and they expose the contribution of the various policy instruments (both farm and non-farm) to the net distortion to farmer incentives. Such a widespread coverage of countries, products, years and policy instruments has allowed this collection of studies to test a wide range of hypotheses suggested by the new political economy literature, including the importance of institutions. As a set it sheds much new light on the underlying forces that have affected incentives facing farmers in the course of national and global economic and political development, and hence on how those distortions might change in the future - or be changed by concerted actions to offset political pressures from traditionally powerful vested interests.Publication Agricultural Price Distortion and Stabilization(World Bank, Washington, DC, 2009-05)This paper describes agricultural policy choices and tests some predictions of political economy theories. It begins with three broad stylized facts: governments tend to tax agriculture in poorer countries, and subsidize it in richer ones, tax both imports and exports more than nontradables and tax more and subsidize less where there is more land per capita. We test a variety of political economy explanations, finding results consistent with hypothesized effects of rural and urban constituents' rational ignorance about small per person effects, governance institutions' control of rent seeking by political leaders, governments' revenue motive for taxation, and the role of time consistency in policy making. We also find that larger groups obtain more favorable policies, suggesting that positive group size effects outweigh any negative influence from free ridership, and that demographically driven entry of new farmers is associated with less favorable farm policies, suggesting the arrival of new farmers erodes policy rents and discourages political activity by incumbents. Another new result is that governments achieve very little price stabilization relative to our benchmark estimates of undistorted prices, and governments in the poorest countries actually destabilize domestic prices.Publication Normalizing Industrial Policy(World Bank, Washington, DC, 2008)The theoretical case for industrial policy is a strong one. The market failures that industrial policies target in markets for credit, labor, products, and knowledge have long been at the core of what development economists study. The conventional case against industrial policy rests on practical difficulties with its implementation. Even though the issues could in principle be settled by empirical evidence, the evidence to date remains uninformative. Moreover, the conceptual difficulties involved in statistical inference in this area are so great that it is hard to see how statistical evidence could ever yield a convincing verdict. A review of industrial policy in three non-Asian settings El Salvador, Uruguay, and South Africa highlights the extensive amount of industrial policy that is already being carried out and frames the need for industrial policy in the specific circumstances of individual countries. The traditional informational and bureaucratic constraints on the exercise of industrial policy are not givens; they can be molded and rendered less binding through appropriate institutional design. Three key design attributes that industrial policy must possess are embeddedness, carrots-and-sticks, and accountability.Publication Political Economy of Public Policies : Insights from Distortions to Agricultural and Food Markets(World Bank, Washington, DC, 2013-05)The agricultural and food sector is an ideal case for investigating the political economy of public policies. Many of the policy developments in this sector since the 1950s have been sudden and transformational, while others have been gradual but persistent. This paper reviews and synthesizes the literature on trends and fluctuations in market distortions and the political-economy explanations that have been advanced. Based on a rich global data set covering a half-century of evidence on commodities, countries, and policy instruments, the paper identifies hypotheses that have been explored in the literature on the extent of market distortions and the conditions under which reform may be feasible.Publication Global Agricultural Trade and Developing Countries(Washington, DC: World Bank, 2005)This book explores the outstanding issues in global agricultural trade policy and evolving world production and trade patterns. Its coverage of agricultural trade issues ranges from the details of cross-cutting policy issues to the highly distorted agricultural trade regimes of industrial countries and detailed studies of agricultural commodities of economic importance to many developing countries. The book brings together the background issues and findings to guide researchers and policymakers in their global negotiations and domestic policies on agriculture. The book also explores the key questions for global agricultural policies, both the impacts of current trade regimes and the implications of reform. It complements the recent agricultural trade handbook that focuses primarily on the agricultural issues within the context of the World Trade Organization (WTO) negotiations (Ingco and Nash 2004).

Publication Assessing the Environmental, Forest, and Other Natural Resource Aspects of Development Policy Lending(Washington, DC, 2008)The operations policy on Development Policy Lending (DPL), approved by the Board in August 2004, requires that the Bank systematically analyze whether specific country policies supported by an operation are likely to have "significant effects" on the country's environment, forests, and other natural resources. The implicit objective behind this requirement is to ensure that there is adequate capacity in the country to deal with adverse effects on the environment, forests, and other natural resources that the policies could trigger, even at the program design stage. DPL operations are associated with a whole array of policies such as macro policy reforms, fiscal policies, and specific sectoral policies, particularly in key sectors such as agriculture, health and education, energy, etc. In some cases, the operation may deal directly with reforms in certain environmentally sensitive sectors such as energy, transport, water and sanitation, agriculture, and forestry. In these cases, there is an obvious need for careful analysis of environmental, natural resource, and forestry impacts. In other cases, such as public sector reform and governance, there is less potential for likely significant impacts on the natural environment and natural resources. The toolkit is designed to be concise and user-friendly. It consists of three specific modules. The first module identifies relevant transmission channels through which the proposed reform would have a likely effect on the identified environmental, forest, and other natural resource priorities. The second module provides assistance in identifying key environmental issues in the country, regions, or sectors likely to be influenced by the DPL program. The third module presents different tools and methodologies for rapid assessment of the likely significant effects of each reform.Publication Mining in Africa(Washington, DC: World Bank and Agence Francaise de developpement, 2017-02-21)This study focuses on the local and regional impact of large-scale gold mining in Africa in the context of a mineral boom in the region since 2000. It contributes to filling a gap in the literature on the welfare effects of mineral resources, which, until now, has concentrated more on the national or macroeconomic impacts. Economists have long been intrigued by the paradox that a rich endowment of natural resources may retard economic performance, particularly in the case of mineral-exporting developing countries. Studies of this phenomenon, known as the “resource curse,” examine the economy-wide consequences of mineral exports. Africa’s resource boom has lifted growth, but has been less successful in improving people’s welfare. Yet much of the focus in academic and policy circles has been on appropriate management of the macro-fiscal and governance risks that have historically undermined development outcomes. This study focuses instead on the fortune of local communities where resources are located. It aims to better inform public policy and corporate behavior on the welfare of communities in Africa in which the extraction of resources takes place.Publication Digital Africa(Washington, DC: World Bank, 2023-03-13)All African countries need better and more jobs for their growing populations. "Digital Africa: Technological Transformation for Jobs" shows that broader use of productivity-enhancing, digital technologies by enterprises and households is imperative to generate such jobs, including for lower-skilled people. At the same time, it can support not only countries’ short-term objective of postpandemic economic recovery but also their vision of economic transformation with more inclusive growth. These outcomes are not automatic, however. Mobile internet availability has increased throughout the continent in recent years, but Africa’s uptake gap is the highest in the world. Areas with at least 3G mobile internet service now cover 84 percent of Africa’s population, but only 22 percent uses such services. And the average African business lags in the use of smartphones and computers as well as more sophisticated digital technologies that catalyze further productivity gains. Two issues explain the usage gap: affordability of these new technologies and willingness to use them. For the 40 percent of Africans below the extreme poverty line, mobile data plans alone would cost one-third of their incomes—in addition to the price of access devices, apps, and electricity. Data plans for small- and medium-size businesses are also more expensive than in other regions. Moreover, shortcomings in the quality of internet services—and in the supply of attractive, skills-appropriate apps that promote entrepreneurship and raise earnings—dampen people’s willingness to use them. For those countries already using these technologies, the development payoffs are significant. New empirical studies for this report add to the rapidly growing evidence that mobile internet availability directly raises enterprise productivity, increases jobs, and reduces poverty throughout Africa. To realize these and other benefits more widely, Africa’s countries must implement complementary and mutually reinforcing policies to strengthen both consumers’ ability to pay and willingness to use digital technologies. These interventions must prioritize productive use to generate large numbers of inclusive jobs in a region poised to benefit from a massive, youthful workforce—one projected to become the world’s largest by the end of this century.Publication Can Medium-Resolution Satellite Imagery Measure Economic Activity at Small Geographies? Evidence from Landsat in Vietnam(World Bank, Washington, DC, 2019-12)This study explores the potential and the limits of medium-resolution satellite data as a proxy for economic activity at small geographic units. Using a commune-level dataset from Vietnam, it compares the performance of commonly used nightlight data and higher resolution Landsat imagery which measures daytime light reflection. The analysis suggests that Landsat outperforms nighttime lights at predicting enterprise counts, employment, and expenditure in simple regression models. A parsimonious combination of the first two moments of the Landsat spectral bands can explain a reasonable share of the variation in economic activity in the cross-section. There is however poor prediction power of either satellite measure for changes over time.Publication Firms' Export Decisions(World Bank, Washington, DC, 2017-01)This paper studies the relationship between access to credit, demand shocks, and export market adjustments using firm-level panel survey data for 24 economies in the Eastern Europe and Central Asian region. The study finds that domestic shocks to demand have a significant influence on the firm's decision to participate in international markets (extensive margin) and on the firm's share of foreign sales (intensive margin). Foreign shocks to demand only affect the firm's share of foreign sales. Conversely, the role of financial constraints on either the extensive or the intensive margin is more nuanced. The results are robust to various specifications of financial constraints and different estimation methods.
