This book was released on with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study proposes the use of partial least squares to determine the key parameters of the perpetual inventory method model of capital stock as a new approach to calculate research and development (R&D) knowledge stocks and R&D elasticities. This approach avoids most of the major problems encountered in the literature that lead to obtaining very high and implausible rates of return to agricultural R&D...Using this approach, we obtain an average R&D elasticity for low- and middle-income (LM) countries of 0.23 and an average rate of return to R&D investment of 6.0 percent, bigger than the average discount rate of 4.2 percent for these countries. Results show that 60 percent of LM countries in our sample are underinvesting in agricultural R&D, as they can get higher returns by investing in this activity than in activities that return the social discount rate.

This book was released on 2021-10-19 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This analysis explores the relationship between agricultural R&D investments and rural poverty reduction, and the prevalence of undernourishment in sub-Saharan Africa (SSA). It uses a panel data set of internationally comparable poverty dis-aggregated by urban and rural areas, country level undernourishment, and ASTI data on R&D investments and derived indicators. The study uses agricultural R&D knowledge stocks (KS) to account for the lagged effects of research through depreciation and gestation period of investments, and applies causal mediation analysis to assess the impact of KS on poverty and hunger and measure the relative contribution of KS-induced agricultural productivity growth on those outcomes. Evidence suggests that, while SSA growth in KS has been relatively slow, it helped reduce rural poverty and undernourishment – the percentage point reduction in rural extreme and moderate poverty of a 1% annual increase in KS is 0.218 and 0.146 percentage points per year, respectively. Mediation analysis indicates that a fifth of the KS effect on extreme rural poverty, and a quarter of the KS effect on moderate rural poverty, can be attributed to KS driven gains in agricultural labor productivity. Likewise, KS growth reduces undernourishment – a 1% annual increase in KS leads to a drop of 0.132 percentage points per year in the prevalence of undernourishment, with about 40% of that effect mediated through gains in agricultural land productivity. These results indicate that KS supports poverty and hunger reduction through benefits on-farm and beyond it. They also suggest that there is room for strengthening the role of R&D KS productivity enhancing innovations. Given the current low levels of investments in R&D and resulting KS, increasing its levels will be critical, but that alone is not sufficient. Policy makers will have to rethink the way the innovations from R&D get scaled up and pay attention to the necessary complementary policies and investments that enable a sustainable pathway leading to greater productivity growth and development impacts.

This book was released on 2022-01-28 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper looks at the prioritization of agricultural value chains (VCs) for the allocation of R&D resources that maximize development outcomes (poverty, growth, jobs, and diets). Considering that growth in VCs affects those various outcomes differently, as expansion pathways result in the diverse use of production factors and inputs, trade-offs from linkages across sectors, and changes throughout the agri-food system, this analysis uses (i) the RIAPA dynamic computable general equilibrium model to identify which agricultural VCs, when expanded through TFP growth, provide the strongest effects on the development outcomes of interest; (ii) the perpetual inventory model (PIM) to represent the lagged effect of research through knowledge stocks of agricultural R&D investments; and (iii) information on the elasticities of VC agricultural activity TFP with respect to agricultural R&D knowledge stocks, to discuss the VC priority allocations of R&D resources in Senegal. Results indicate that no one VC (crop- or livestock-related) is the most effective at improving all development outcomes. When accounting for policy preferences that attribute relative priority weight to development objectives, results (based on a ranking scale) indicate that R&D investments for maximizing development objectives can be most effective in Senegal’s VCs for traditional export crops (growth, diets, jobs, and to some extent poverty), groundnuts (poverty, diets, and jobs), rice (poverty and jobs), poultry/eggs (diets and jobs), sorghum/millet (poverty and growth), and cattle (diets and growth). Other promising VCs with potential effects at scale if strategically targeted include vegetables (poverty, diets, and jobs), oilseeds (poverty and growth), and fruits (diets and jobs). While these results can inform strategies aimed at improving multiple development outcomes, future modeling needs to focus on deepening the standardization and integration of R&D investments costs into the framework, disentangle the relevance of different types of R&D investments sources, and bring together other factors and complementary agrifood system investment dimensions relevant to sustainable and inclusive agricultural VC growth.
Download or read book Returns to R D investment to inform priority setting in the One CGIAR and NARS written by Nin-Pratt, Alejandro and published by Intl Food Policy Res Inst. This book was released on 2022-02-10 with total page 78 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2019 report of the Global Commission on Adaptation for accelerated action to adapt to climate change included a call for increased allocation of resources to international agricultural research. The production and adaptation challenges faced by agriculture will be most acutely felt in Africa and South Asia, focus regions of the CGIAR, the world’s largest public food systems research network. These challenges come at a time when the CGIAR is undergoing a transformation of its partnerships, knowledge, assets and global presence, emerging as One CGIAR, aimed at sharpening its mission and impact focus to 2030 and beyond, in line with the Sustainable Development Goals. Evidence on the impacts of CGIAR research since the 1980s have consistently found high rates of return to investment. How could this evidence on the performance of the CGIAR and its partnership with NARS in developing regions be used to inform investment priority setting and to achieve the One CGIAR goals in the coming years? We used detailed R&D investment data from the CGIAR, NARS (ASTI) and evidence from the literature on returns to CGIAR investment by crop and region to develop and calibrate a model of R&D investment that allows us to conduct priority-setting analysis of alternative CGIAR investment across research activities and regions. The model developed can be linked to global partial equilibrium and economy-wide forward-looking models to analyze the effect of different CGIAR investment options under alternative future scenarios. We checked the plausibility of the results obtained by the model calculating the Benefit-Cost ratio of historical CGIAR investments and found that each dollar invested by the CGIAR between 1971 and 2018 returned almost 10 dollars in output as the result of increased productivity, which is within the range of returns found by most recent meta-analyses impact of CGIAR investment. An application of the model to SSA shows that the best results for the CGIAR are obtained from investments in cassava and potato in Southern Africa; yams, sorghum, cassava and groundnuts in West Africa; cassava in East Africa and groundnuts and shoats in the Sahel.

This book was released on 1999 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: April 1999 - The sensitivity of empirical results to potential data errors and model misspecification can yield misleading policy implications and investment signals. A widely disseminated study of the impact of the training and visit (T & V) system of management for extension services in Kenya is a striking example of how innocuous data errors and alternative specifications lead to strikingly different results. Gautam and Anderson revisit the widely disseminated results of a study (Bindlish and Evenson 1993, 1997) of the impact of the training and visit (T & V) system of management for public extension services in Kenya. T & V was introduced in Kenya by the World Bank and has since been supported through two successive projects. The impact of the projects continues to be the subject of much debate. Gautam and Anderson's paper suggests the need for greater vigilance in empirical analysis, especially about the quality of data used to support Bank policy and the need to validate potentially influential findings. Using household data from 1990, Bindlish and Evenson found the returns from extension to be very high. But Gautam and Anderson find that the returns estimated by Bindlish and Evenson suffer from data errors, and limitations imposed by cross-sectional data. After correcting for several data processing and measurement errors, the authors show the results to be less robust than reported by Bindlish and Evenson and highly sensitive to regional effects. When region-specific effects are included, a positive return to extension cannot be established, using Bindlish and Evenson's data set and cross-sectional model specifications. After testing the robustness of results using a number of tests, Gautam and Anderson could not definitively establish the factors underlying strong regional effects, largely because of the limitations imposed by the cross-sectional framework. Household panel data methods would have allowed greater control for regional effects and would have yielded better insight into the impact of extension. The impact on agricultural productivity in Kenya expected from T & V extension services is not discernible from the available data, and the impact may vary across districts. The hypothesis that T & V had no impact in Kenya between 1982 and 1990 cannot be rejected. The sample data fail to support a positive rate of return on the investment in T & V. This paper-a product of the Sector and Thematic Evaluation Division, Operations Evaluation Department-is part of a larger exploration by the department of the effects of the investment in agricultural extension in Kenya.

Download or read book The Chicago Plan Revisited written by Mr.Jaromir Benes and published by International Monetary Fund. This book was released on 2012-08-01 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: At the height of the Great Depression a number of leading U.S. economists advanced a proposal for monetary reform that became known as the Chicago Plan. It envisaged the separation of the monetary and credit functions of the banking system, by requiring 100% reserve backing for deposits. Irving Fisher (1936) claimed the following advantages for this plan: (1) Much better control of a major source of business cycle fluctuations, sudden increases and contractions of bank credit and of the supply of bank-created money. (2) Complete elimination of bank runs. (3) Dramatic reduction of the (net) public debt. (4) Dramatic reduction of private debt, as money creation no longer requires simultaneous debt creation. We study these claims by embedding a comprehensive and carefully calibrated model of the banking system in a DSGE model of the U.S. economy. We find support for all four of Fisher's claims. Furthermore, output gains approach 10 percent, and steady state inflation can drop to zero without posing problems for the conduct of monetary policy.

This book was released on 2022-07-06 with total page 260 pages. Available in PDF, EPUB and Kindle. Book excerpt: This year’s report should dispel any lingering doubts that the world is moving backwards in its efforts to end hunger, food insecurity and malnutrition in all its forms. We are now only eight years away from 2030, but the distance to reach many of the SDG 2 targets is growing wider each year. There are indeed efforts to make progress towards SDG 2, yet they are proving insufficient in the face of a more challenging and uncertain context. The intensification of the major drivers behind recent food insecurity and malnutrition trends (i.e. conflict, climate extremes and economic shocks) combined with the high cost of nutritious foods and growing inequalities will continue to challenge food security and nutrition. This will be the case until agrifood systems are transformed, become more resilient and are delivering lower cost nutritious foods and affordable healthy diets for all, sustainably and inclusively.

Download or read book The Western Range Revisited written by Debra L. Donahue and published by University of Oklahoma Press. This book was released on 1999 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Livestock grazing is the most widespread commercial use of federal public lands. The image of a herd grazing on Bureau of Land Management or U.S. Forest Service lands is so traditional that many view this use as central to the history and culture of the West. Yet the grazing program costs far more to administer than it generates in revenues, and grazing affects all other uses of public lands, causing potentially irreversible damage to native wildlife and vegetation. The Western Range Revisited proposes a landscape-level strategy for conserving native biological diversity on federal rangelands, a strategy based chiefly on removing livestock from large tracts of arid BLM lands in ten western states: Arizona, California, Colorado, Idaho, Nevada, New Mexico, Oregon, Utah, Washington, Wyoming. Drawing from range ecology, conservation biology, law, and economics, Debra L. Donahue examines the history of federal grazing policy and the current debate on federal multiple-use, sustained-yield policies and changing priorities for our public lands. Donahue, a lawyer and wildlife biologist, uses existing laws and regulations, historical documents, economic statistics, and current scientific thinking to make a strong case for a land-management strategy that has been, until now, "unthinkable." A groundbreaking interdisciplinary work, The Western Range Revisited demonstrates that conserving biodiversity by eliminating or reducing livestock grazing makes economic sense, is ecologically expedient, and can be achieved under current law.
