Knowledge gaps remain as to how longer-term public investments (PI) such as agricultural research and development (R&D), and short-term interventions through other public expenditures in agriculture (PEA) complement each other in enhancing productivity and efficiency in the agrifood sector. This study attempts to partly fill this gap by using nationally representative panel household survey data, subnational PEA data, locations of national agricultural R&D, and various spatial agroclimatic data in Nigeria. The analyses generally indicate that marginal returns to agricultural inputs/services (fertilizer, agricultural mechanization, irrigation, extension, agricultural equipment, and family lab...
This paper proposes a novel methodology for calculating marginal abatement cost curves (MACCs) for public finance in agriculture using granular data on specific activities from investment projects. [Author] The proposed MACCs target public investment decision makers from the international and national financing institutions, as well as governments. [Author] The methodology is based on information obtained from agricultural projects implemented by international funding institutions (IFIs) and carbon accounting appraisals conducted using the Food and Agriculture Organization of the United Nations (FAO) EX-Ante Carbon-balance Tool (EX-ACT). [Author] The curves are estimated through a bottom-up ...
Policymakers in Papua New Guinea face difficult choices as to how best to promote economic growth and reduce poverty in the context of vast differences in technology and infrastructure across the country. Fluctuations in world prices of petroleum, minerals, and export crops complicate the management of the economy because of their large impacts on export earnings and government revenues, as well as household welfare. Moreover, other shocks, such as the Covid-19 pandemic that shut down major parts of the economies of PNG and the rest of the world, have far-reaching effects on various economic sectors, as well as the health and welfare of the population. This paper presents an analysis of inve...
Escalating energy demand may be the most important issue facing the United States and the world today. There is little disagreement that research and development (R&D) is needed to develop new energy technologies for the future; however, there is less agreement over the specific research agenda to be pursued and how that agenda is funded. This book addresses the social importance of new energy technologies, illustrates policy-relevant applications of evaluation techniques and proposes new perspectives for a US energy investment strategy. Through detailed examples related to solar, geothermal, and vehicle technologies, the authors outline the need for robust evaluation methods to document soc...
International cooperation has never been more needed, but the current system of "aid" is outdated and ineffective. The Future of Aid calls for a wholesale restructuring of the aid project, a totally new approach fit for the challenges of the 21st century: Global Public Investment. Across the world, billions of people are struggling to get by in unequal and unsustainable societies, and international public finance, which should be part of the answer, is woefully deficient. Engagingly written by a well-known expert in the field, The Future of Aid calls for a series of paradigm shifts. From a narrow focus on poverty to a broader attack on inequality and sustainability. From seeing international...
Sierra Leone has made significant strides to rebuild its public infrastructure after the devastating civil war, but the desperate infrastructure needs remain. At the end of the conflict in 2002, the country was left with virtually no infrastructure. Redevelopment of public infrastructure was ignited by the mining boom, which started in the late 2000s. Over the period 2008−18, public investment averaged 6.5 percent of gross domestic product (GDP), which has translated into an estimated capital stock of about 65 percent in constant 2011 GDP. However, a level of public investment is still lower than neighboring countries by about one percentage point. The level of capital stock per capita is one of the lowest in the region, only slightly above that of Liberia. Some districts still have no paved roads, no electricity, and no water systems, almost 20 years after the war.
This new edition incorporates revised guidance from H.M Treasury which is designed to promote efficient policy development and resource allocation across government through the use of a thorough, long-term and analytically robust approach to the appraisal and evaluation of public service projects before significant funds are committed. It is the first edition to have been aided by a consultation process in order to ensure the guidance is clearer and more closely tailored to suit the needs of users.
