This book was released on 2016-04-21 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper studies the decision of a firm that sells an experience good to delegate quality control to an independent monitor. In an infinitely repeated game consumers’ trust provides incentives to (1) acquire information about whether the good is defective and (2) withhold the good from sale if it is defective. If third-party reports are observable to consumers, delegation of monitoring lessens the first and dispenses with the second moral hazard concern but also creates agency costs due to either limited liability or lack of commitment. In equilibrium the firm controls quality without an independent monitor only if trades are sufficiently frequent and consumer information about quality is sufficiently precise. This result holds under different assumptions about feasible contracts, collusion, verifiability of reports, joint inspections, and the number of firms that hire the third-party monitor. If third-party reports are not publicly observed, delegation can be optimal only if two or more firms hire the third-party monitor because then both moral hazard concerns are present under delegation.

Book excerpt: This paper studies the case in which a firm delegates quality control to an independent monitor. In a repeated game, consumers' trust provides incentives to acquire information about whether the good is defective, and withhold defective goods from sale. If third-party reports are observable to consumers, delegation lessens the first and dispenses with the second moral hazard concern but also creates agency costs. Internal quality control is optimal only if trades are sufficiently frequent and consumer information is sufficiently precise. This result holds in the presence of the possibility of collusion, fully non-verifiable presale information, and economies of scale in external quality control.
Download or read book Understanding compliance in programs promoting conservation agriculture written by Ward, Patrick S. and published by Intl Food Policy Res Inst. This book was released on 2016-05-13 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Land degradation and soil erosion have emerged as serious challenges to smallholder farmers throughout southern Africa. To combat these challenges, conservation agriculture (CA) is widely promoted as a sustainable package of agricultural practices. Despite the many potential benefits of CA, however, adoption remains low. Yet relatively little is known about the decision-making process in choosing to adopt CA. This article attempts to fill this important knowledge gap by studying CA adoption in southern Malawi. Unlike what is implicitly assumed when these packages of practices are introduced, farmers view adoption as a series of independent decisions rather than a single decision. Yet the adoption decisions are not wholly independent. We find strong evidence of interrelated decisions, particularly among mulching crop residues and practicing zero tillage, suggesting that mulching residues and intercropping or rotating with legumes introduces a multiplier effect on the adoption of zero tillage.

This book was released on 2016-05-03 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: When an outbreak of an infectious disease is suspected, a local health agency may notify a state or federal agency and request additional resources to investigate and, if necessary, contain it. However, due to capacity constraints, state and federal health agencies may not be able to grant all such requests, which may give an incentive to local agencies to request help strategically. We study a model of detection and control of an infectious disease by local health agencies in the presence of imperfect information about the likelihood of an outbreak and limited diagnostic capacity. When diagnostic capacity is rationed based on reports of symptoms, the decision to report symptoms or not creates a trade-off. On the one hand, rigorous testing allows one to make an informed disease control decision. On the other hand, it also increases the probability that the disease will spread from an untested area where fewer precautionary measures are taken. Symptoms are overreported (respectively, reported truthfully, or underreported) when the cost of disease control is sufficiently small (respectively, in some intermediate range, or sufficiently large). If the disease incidence decreases or infectiousness increases, symptoms are reported less frequently. If the precision of private signals increases, the extent of overreporting of symptoms may increase. For different values of the parameters it can be socially optimal to subsidize or tax requests for additional investigations and confirmatory testing.

Download or read book Long term drivers of food and nutrition security written by Laborde Debucquet, David and published by Intl Food Policy Res Inst. This book was released on 2016-05-18 with total page 44 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 2015 Global Hunger Index suggests that despite progress in reducing hunger worldwide, hunger levels in 52 of 117 countries in the 2015 Global Hunger Index remain “serious” or “alarming.” Since achieving and maintaining food and nutrition security (FNS) remains a goal for all countries, it is important to understand the individual, national, and global factors that affect FNS. This paper proposes an analytical framework to identify and analyze the respective roles of key long-term drivers of FNS. We start by identifying what the key variables affecting FNS are at the household and country level, and then we continue by defining what the main exogenous or endogenous drivers affecting these variables are. We discuss the key drivers of both aggregated food supply and demand and therefore their impact on prices. Specifically, for aggregated food demand, we discuss demographic factors, income growth, changes in dietary preferences, aggregated domestic distortions, and overall quality of the food system. With respect to the drivers of aggregated food supply, we discuss land available for food products and the drivers behind land availability, the share of waste/losses generated by the food system, and the normalized average yield. We define yield as the amount of nutrients produced by unit of land. It depends both on the physical yield of the crop or the livestock and on the quality of the food produced. It also can be affected by the changes in production patterns linked to the different dietary patterns of the consumers and by climate change. We emphasize the fact that in many cases, key drivers may have ambiguous effects on the FNS situation of different agents. For instance, more liberal trade policies will affect real income, terms of trade, demand and supply, returns of factors, foreign direct investments, and food prices and thus may lead to the improvement of the global-level FNS, that is, the FNS of the majority of the population. At the same time, more liberal trade policies may bring food insecurity to some households. Therefore, careful quantitative assessment is needed for each policy option. Finally, we propose a typology of variables that will help modelers adapt their models to study the different drivers through both direct and indirect effects.
Download or read book Boserupian pressure and agricultural mechanization in modern Ghana written by Cossar, Frances and published by Intl Food Policy Res Inst. This book was released on 2016-04-29 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The adoption of machinery in agricultural production in Africa south of the Sahara has been far behind the level of mechanization found in Asia and Latin America. However, recent survey data have revealed high levels of machinery use in localized areas of cereal production in northern Ghana. A survey conducted by the International Food Policy Research Institute, in partnership with the Savannah Agriculture Research Institute, found that in some areas more than 80 percent of farmers were using machinery for at least one operation. This paper considers the theoretical drivers of agricultural intensification, as outlined by Boserup, Pingali, and Binswanger, and the extent to which they are able to explain the spatial variation in machinery use found in northern Ghana. Population pressure, market access, and agroecological conditions are considered key drivers that cause farmers to find ways to increase productivity and adopt new technologies. Combining survey data with geospatial datasets, the empirical analysis finds that population growth and travel time to the local urban center explain a significant and large proportion of the variation in machinery use by farmers.
Download or read book Global and regional pulse economies written by Joshi, Pramod Kumar and published by Intl Food Policy Res Inst. This book was released on 2016-07-22 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: The pulse sector is undergoing dynamic changes globally and in several regions and countries to meet the challenge of growing demand in the face of sluggish production growth. Realizing the importance of pulses in the human diet, 2016 has been declared the International Year of Pulses (IYP). This report captures the dynamics of the pulse sector during the last three decades. The examination of pulse supply, demand, uses, trade, prices, and outlook would help researchers and policy makers make more informed decisions related to the sector. Pulse-based food is an important source of dietary protein and essential minerals, particularly for the vegetarian population. At the global level, the average share of pulses is only 5 percent of the total protein consumption but their contribution in several developing countries range between 10 and 40 percent. To meet the growing demand and raise their per capita availability, countries made efforts to increase production and explore trade opportunities to augment domestic supply. Overall between 1980 and 2013, pulses production at the global level grew at an annual rate of 1.3 percent but there were, however, two phases of pulses production at the global level. While there was almost a period of stagnation in production of pulses during the1990s, production has sharply increased since 2005. The bulk of the increase in production came from developing countries where both area and yield growth (from a low base) contributed to the production. For developed countries—where production also grew—the center of production shifted from Europe to North America and Oceania. For developing countries, two new centers of production emerged in Eastern Africa and Southeastern Asia (Myanmar).
Download or read book Anchoring Bias in Recall Data written by Godlonton, Susan and published by Intl Food Policy Res Inst. This book was released on 2016-05-20 with total page 36 pages. Available in PDF, EPUB and Kindle. Book excerpt: Understanding the magnitude and source of measurement biases in self-reported data is critical to effective economic policy research. This paper examines the role of anchoring bias in self-reports of objective and subjective outcomes under recall. The research exploits a unique panel survey data set collected over a three-year period from four countries in Central America. It assesses whether respondents use their reported value of specific measures from the most recent survey period as a cognitive heuristic when recalling the value from a previous period, while controlling for the value they reported earlier. We find strong evidence of sizable anchoring bias in self-reported retrospective indicators for both objective measures (household and per capita income, wages, and hours spent on the household’s main activity) and subjective measures (reports of happiness, health, stress, and well-being). In general, we also observe a larger bias in response to negative changes for objective indicators and a larger bias in response to positive changes for subjective indicators.

This book was released on 2016-05-27 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: The rise of mixed methods approaches to development-oriented research has brought new attention to qualitative research methods. This paper describes the use of qualitative approaches to illuminate gender relations in agricultural development research and project implementation. For gender research, qualitative methods can be particularly helpful in illuminating how men and women view their lives. Drawing on literature about social science methods and linking it to recent examples of qualitative methods employed in research and development projects, the paper argues for greater precision in key concepts of gender research, starting with sex and gender. From the many possible qualitative methods used in development work, the paper focuses on several common observational (both direct and participatory) and interview techniques, the latter including key informant and group interviews and focus group discussions. Researchers use various techniques to gather different types of information, for example, mapping techniques to understand men’s and women’s different types of knowledge about their environment and eliciting in-depth information on a single topic with key informants. In a brief discussion of the analysis of qualitative data, the paper notes that informant responses are not “the truth” but need to be assessed against other sources of data. Finally, there is a short discussion of how qualitative data have been used in comparative work. The paper concludes that the results of good qualitative research on gender relations can help identify the locally specific pathways needed to achieve gender-transformative development approaches.
Download or read book Can labor market imperfections explain changes in the inverse farm size productivity relationship written by Deininger, Klaus and published by Intl Food Policy Res Inst. This book was released on 2016-06-24 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: To understand whether and how inverse relationship between farm size and productivity changes when labor market performance improves, we use large national farm panel from India covering a quarter-century (1982, 1999, 2008) to show that the inverserelationship weakened significantly over time, despite an increase in the dispersion of farm sizes. A key reason was the substitution of capital for labor in response to nonagricultural labor demand. In addition, family labor wasmore efficient than hired labor in the 1982–1999 period, but not during the 1999–2008period.In line with labor market imperfections as a key factor, separability of labor supply and demand decisions cannot be rejected in the second period,except in villages with very low nonagricultural labor demand.
Download or read book Linking smallholder farmers to commercial markets written by Ebata, Ayako and published by Intl Food Policy Res Inst. This book was released on 2016-07-01 with total page 32 pages. Available in PDF, EPUB and Kindle. Book excerpt: Access to modern commercialization channels is key for smallholder farmers to be able to move away from subsistence farming and overcome poverty. However, achieving that goal is challenging for smallholders given their lack of appropriate managerial practices, production technology and infrastructure. This paper examines the effect of receiving training in two different entrepreneurial practices designed to link farmers to commercial markets: one direct aimed at the individual and farmer-association level and another indirect focused at the community level. We exploit an extensive panel dataset of staple bean farmers in Nicaragua who participated in a program run by a nongovernmental organization between 2007–2012. We find that the two market-linkage training activities had opposite effects on the commercialization of beans, especially on the intensive margin or volume of sales. While receiving direct training on entrepreneurial practices is positively associated with sales in commercial markets, training on municipality engagement (ME) activities is negatively associated. The market-linkage activities mainly affected entrant farmers as opposed to those already participating in commercial markets. We further find varying effects of the ME activities by plot size and leadership position. Additional results show that training activities that appear to work for bean producers do not necessarily work for other crop producers, and vice versa.

This book was released on 2016-06-09 with total page 28 pages. Available in PDF, EPUB and Kindle. Book excerpt: Spatial interactions are essential drivers of price transmission mechanisms and may significantly affect any food’s policy outcomes. However, spatial aspects seem to be generally overlooked when analyzing price transmission. This paper attempts to fill this gap by highlighting the usefulness of spatial interaction and models for market integration analysis. A spatial dynamic panel datamodel is presented and applied to Niger’s millet market. Empirical results show that (1) the millet market is partly integrated, (2) locally traded commodities (millet and sorghum) are linked by a cross-commodity price transmission, (3) most imported cereals prices, which for Niger is maize and rice, did not affect the millet market, and (4) no cross-regions price transmissionoccurred for the millet market.

Download or read book Agricultural mechanization and agricultural transformation written by Diao, Xinshen and published by Intl Food Policy Res Inst. This book was released on 2016-04-29 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: A renewed focus on agriculture’s potential contribution to economic transformation in Africa has resulted in increased attention paid to agricultural mechanization. African agriculture still relies predominantly on human muscle power despite anecdotal evidence on urbanization and rising rural wages, in contrast to other developing regions that have experienced rapid increases in agricultural mechanization during the past few decades. Past state-led mechanization pushes in Africa often failed due to insufficient understanding of the nature of demand for mechanization technologies among farmers and insufficient knowledge of private-sector functions. This background paper reviews the factors likely to influence farmer demand for mechanization in Africa and details different existing and potential mechanization supply models. Although an empirical analysis of mechanization demand and the effectiveness of supply chains is beyond the scope of this paper, in part due to data limitations, this paper suggests that demand for mechanization may be emerging in some parts of Africa. It also suggests that private-sector-driven supply models are better positioned to meet this demand than direct government involvement and certain types of subsidized programs. The paper then identifies possible areas for government support to complement private-sector leadership in developing mechanization supply chains. Nevertheless, significant further research is required to better understand the changing nature of mechanization demand in Africa and the extent and effectiveness of different supply models in meeting it.
