Book Description
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.

Book Description
Self-reported retrospective survey data is widely used in empirical work but may be subject to cognitive biases, even over relatively short recall periods. This paper examines the role of anchoring bias in self-reports of objective and subjective outcomes under recall. We use a unique panel-survey dataset of smallholder farmers from four countries in Central America collected over a period of three years. We exploit differences between recalled and concurrent responses to quantify the degree of mental anchoring in survey recall data. We assess whether respondents use their reported value for the most recent period as a cognitive heuristic when recalling the value from a previous period, while controlling for the value they reported earlier. The results show strong evidence of sizeable anchoring bias in self-reported retrospective indicators for both objective measures (income, wages, and working hours) and subjective measures (reports of happiness, health, stress, and well-being). We also generally observe a larger bias in response to negative changes for objective indicators and a larger bias in response to positive changes for subjective indicators.

Can labor market imperfections explain changes in the inverse farm size-productivity relationship ?
Author: Deininger, Klaus
Publisher: Intl Food Policy Res Inst
ISBN:
Category : Political Science
Languages : en
Pages : 32
Book Description
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.

A systematic review of cross-country data initiatives on agricultural public expenditures in developing countries
Author: Anson, Richard
Publisher: Intl Food Policy Res Inst
ISBN:
Category : Political Science
Languages : en
Pages : 76
Book Description
This study reviews all of the relevant data and analytical initiatives or activities that focus on or include agricultural public expenditure (AgPE) in developing and transitioning countries. In addition to taking stock of such initiatives, we carry out a comparison of relevant features, describe differences and similarities, and identify possible avenues for greater collaboration and complementarity, including the use of selected empirical examples arising from the comparative review.

A farm-level perspective of the policy challenges for export diversification in Malawi
Author: Johnson, Michael E.
Publisher: Intl Food Policy Res Inst
ISBN:
Category : Political Science
Languages : en
Pages : 52
Book Description
The primary goal of the study is to investigate the potential to expand oilseeds, specifically soybeans,as an alternative commercialcrop to tobacco among Malawian farmers. A principal motivation for undertaking the study at the microeconomic level is to determine, in a theoretically consistent fashion, the type of policy and economic environment under which farmers begin to shift more of their scarce resources to oilseed production.The study aims to provide recommendations to a growing demand among policy makers and development partners for a greater diversification of exports and crop production systems of the majority smallholder farmers in Malawi. Using representative farm models, the study examinesthe potential for expanding production of soybeans among typical smallholder farming systems in Malawi. The results will help guide future policies and investments targeted at promoting greater crop diversification and incomes, in order to reduce poverty and malnutrition in Malawi. Given the amount of labor and land resources allocated to maize production for food security purposes, we also consider the policy challenges that emerge for crop diversification as a result

The distribution of power and household behavior
Author: Wouterse, Fleur Stephanie
Publisher: Intl Food Policy Res Inst
ISBN:
Category : Political Science
Languages : en
Pages : 28
Book Description
Niger is a landlocked Sahelian country, two-thirds of which is in the Sahara desert. Although only one-eighth of the land considered arable, more than 90 percent of Niger’s labor force is employed in agriculture, which is predominantly subsistence oriented. Food security remains a major challenge in rural areas of Niger, and gender is a significant basis for the inequality among household members with respect to access to land. Access to land, which is a measure of the income-earning potential of an individual, is an important determinant of the distribution of bargaining power within the household. Because households may not act in a unitary manner when making decisions, the power of individuals within the household to exert their own preferences may determine welfare outcomes, such as spending on nutritious foods or healthcare. In this paper, we use new data for Niger and regression analyses to assess the importance of the intrahousehold distribution of power for the behavior of rural households. Our results reveal that men are significantly more empowered than women in rural households in Niger and that social protection programs such as water, sanitation, and hygiene (WASH) and food-for-training contribute significantly to the empowerment of women. Our findings also point to the validity of the collective approach to modeling household behavior, as the distribution of power was shown to affect household behavior. In particular, we found that an increase in power in favor of the adult female significantly increases expenditures on healthcare and reduces spending on vices (cigarettes and alcohol).

Assessing the impacts of COVID-19 on the coffee value chain in Guatemala: Evidence from coffee growers in the Midwest and East
Author: Hernandez, Manuel A.
Publisher: Intl Food Policy Res Inst
ISBN:
Category : Political Science
Languages : en
Pages : 21
Book Description
Coffee is a growth market. Current estimates indicate that global coffee production (in volume) has increased by more than 60% since the 1990s. Coffee is produced by around 25 million farmers, which are mainly smallholders in developing and least developed countries, and over 70% of the coffee produced is exported, resulting in about 20 billion US dollars annual foreign exchange earnings (ICO, 2020). COVID-19 represented a severe joint supply and demand shock to the global coffee sector, particularly during the first months after the start of the pandemic. As noted by Hernandez et al. (2020), the coffee industry experienced important disruptions downstream the value chain, including the functioning of key export infrastructure and international shipping, which combined with local currency devaluations and volatile coffee prices, which resulted in significant challenges for coffee growers, farm workers, and traders.
