Gender differences in marketing styles

Recent research has found that men trade stocks more frequently than women and receive a lower price as a result. The behavioral finance literature attributes this greater trading activity to men's overconfidence. Women's lack of overconfidence and past agricultural economics research suggest the possibility that women may be better at marketing grain than men. This article uses actual transactions of farmers marketing wheat and also finds that men trade more often than women. Women also sell two weeks later in the marketing year. There is no direct effect of gender on price received, but by storing longer women receive 1.4 cents/bushel less than men, on average. In contrast to the arguments in previous research, we argue that men's greater number of trades can be better explained by men enjoying trading rather than by overconfidence.     

An Assessment of Gender Discrimination in Household Expenditure on Education in India

Gender discrimination in household expenditure on education has led to unsatisfactory progress in educational attainment for women in many countries across the world. It has been observed that households across different states in rural and urban India prefer to incur more expenditure on education for male members than for females. Kingdon (2005) [Where has all the bias gone? Detecting gender bias in the intra-household allocation of educational expenditure, Economic Development and Cultural Change, 53(2), 409–452] has observed significant gender bias in household educational expenditure in a number of Indian states utilizing the household survey data of the National Council of Applied Economic Research, New Delhi. Other researchers, such as Chaudhuri & Roy (2006) [Do parents spread educational expenditure evenly across the two genders? Evidence from two North Indian states, Economic and Political Weekly, 41, pp. 5276–5282] and Lancaster et al. (2008) [Household expenditure patterns and gender bias: evidence from selected Indian states, Oxford Development Studies, 36(2), 133–157], have also confirmed the presence of significant gender bias in the expenses incurred on education by households in India. However, few of these studies are based on the analysis of sufficiently large, contemporary datasets, and hence they are unable to provide a picture of gender discrimination at the disaggregated level, i.e. at the state level. Since there is wide variation in social, cultural, anthropometrical, economic and many other factors among Indian states, it is important to analyse gender disparity in India at the level of the state. Here, utilizing individual-level data on educational expenditure from the 64th round of the National Sample Survey, an attempt is made to assess the current scenario in gender inequality in household educational expenditure in India at both the national and state level. It is observed that significant gender disparity exists in intra-household educational expenses and that this discrimination is not confined to the “backward” or developing states in India.     

Occupational sex segregation in agriculture: Evidence on gender norms and socio-emotional skills in Nigeria

Occupational sex segregation is a key driver of the gender gap in earnings. Using data from 11,691 aspiring agribusiness entrepreneurs in Nigeria, this article explores factors that drive sectoral choice, gender differences in the choice decision, and especially the role played by norms around gender roles. When given a choice of 11 agricultural value chains in a government program, we find the majority (54 percent) of the applicants chose to enter into the poultry value chain, and women were more likely to choose poultry than men. This article finds evidence of more restrictive gender norms in Northern Nigeria states, which lowers women's likelihood of entering into agricultural value chains where the potential for profit may be higher. The gender bias in sectoral choice is also attributed to differences in work experience especially in agricultural activities and in the chosen value chain, as well as in land ownership. Women with more experience in male-dominated agricultural value chains exhibit lower self-efficacy, which could reflect the challenges they face when deviating from social norms to operate within nontraditional value chains.     

Seasonal Adjustment in a Market for Female Agricultural Workers

This article explores seasonal adjustment in the market for temporary agricultural labor. We estimate a model of participation allowing for unobserved heterogeneity and endogeneity/selection bias using daily observations from Chilean panel data, and a model of daily earnings. Results indicate that seasonal wage variation is an important aspect of labor-market adjustment, contributing to a large change in labor force participation. The labor force participation rate of women is significantly more elastic to changes in the expected wage than is that for men. Nonetheless, we find evidence of substantial open unemployment during the slack season, especially for females, probably due to frictional and efficiency wage effects.     

The nexus between gender,collective action for public goods and agriculture: evidence from Malawi

Across the developing world, public goods exert significant impacts on the local rural economy in general and agricultural productivity and welfare outcomes in particular. Economic and social‐cultural heterogeneity have, however, long been documented as detrimental to collective capacity to provide public goods. In particular, women are often underrepresented in local leadership and decision‐making processes, as are young adults and minority ethnic groups. While democratic principles dictate that broad civic engagement by women and other groups could improve the efficiency and effectiveness of local governance and increase public goods provision, the empirical evidence on these hypotheses is scant. This article develops a theoretical model highlighting the complexity of constructing a “fair” schedule of individual contributions, given heterogeneity in costs and benefits that accrue to people depending, for instance, on their gender, age, ethnicity, and education. The model demonstrates that representative leadership and broad participation in community organizations can mitigate the negative impacts of heterogeneity on collective capacity to provide public goods. Nationally representative household survey data from Malawi, combined with geospatial and administrative information, are used to test this hypothesis and to estimate the relationship between collective capacity for public good provision and community median estimates of maize yields and household consumption expenditures per capita. The analysis shows that similarities between the leadership and the general population in terms of gender and age, and active participation by women and young adult in community groups, alleviate the negative effects of heterogeneity and increase collective capacity, which in turn improves agriculture productivity and welfare.     

Bias from Farmer Self‐Selection in Genetically Modified Crop Productivity Estimates: Evidence from Indian Data

In the continuing debate over the impact of genetically modified (GM) crops on farmers of developing countries, it is important to accurately measure magnitudes such as farm‐level yield gains from GM crop adoption. Yet most farm‐level studies in the literature do not control for farmer self‐selection, a potentially important source of bias in such estimates. We use farm‐level panel data from Indian cotton farmers to investigate the yield effect of GM insect‐resistant cotton. We explicitly take into account the fact that the choice of crop variety is an endogenous variable which might lead to bias from self‐selection. A production function is estimated using a fixed‐effects model to control for selection bias. Our results show that efficient farmers adopt Bacillus thuringiensis (Bt) cotton at a higher rate than their less efficient peers. This suggests that cross‐sectional estimates of the yield effect of Bt cotton, which do not control for self‐selection effects, are likely to be biased upwards. However, after controlling for selection bias, we still find that there is a significant positive yield effect from adoption of Bt cotton that more than offsets the additional cost of Bt seed.     

Relative efficiency of women as farm managers: Profit function analysis in Côte d'Ivoire

The efficiency of women farmers in the agricultural sector of developing countries is passionately debated. Very few studies have examined this issue in African agriculture. All previous studies were based on production functions, but have been criticised as suffering from simultaneous equation bias because the input levels are endogenous. The profit function method avoids these problems. No previous study has used the profit function method to lest for technical, allocative and economic efficiency differences between women and men farmers. The objective of this paper was to determine whether women rice farmers are less efficient than men rice farmers in Côte d'Ivoire using the restricted normalised profit function method. Our results show that the relative degree of efficiency of women is similar to that of men. The paper provides empirical support for efforts to eliminate bias against women farmers in African agriculture.     

Women’s Labour Contribution to Productivity and Efficiency in Agriculture: Empirical Evidence From Bangladesh

This article examines the contribution of women’s labour input to productivity and efficiency in crop farming using a large survey dataset of 1,839 households from 16 villages in two agro‐ecological regions of Bangladesh. Results reveal that female labour accounts for a substantial 28% of total labour use (mainly supplied from the family) and contributes significantly to productivity as well as technical efficiency. Contrary to expectation, the cost share of female labour input is significantly higher than the male share, and has a substitution relationship with all other inputs, including male labour. The estimated mean level of technical efficiency is 0.90, implying that crop output might be increased by 10% by eliminating technical inefficiency. Both male and female education have a significant impact on improving technical efficiency. Other significant technical efficiency shifters are farming experience, family size and crop diversification. Owner operators are found to be technically inefficient relative to the tenants. Policy implications include creation of a hired labour market for female labour so that more women can be involved in the production process, and can contribute to towards improving productivity and efficiency. In addition, investment in education for both men and women, strategies to promote crop diversification and effective regulation/modification of the tenancy market will significantly improve technical efficiency in this case.     

Effects of microcredit and other loans on female empowerment in Bangladesh: the borrower's gender influences intra‐household resource allocation

This article examines microcredit's effectiveness in empowering women borrowers in rural Bangladesh. It does so by examining how gender‐specific borrowing activities influence household expenditures which are either specifically of interest to men or women, and by examining the effects of all loans rather than only those provided by microcredit organizations. The article uses a quasi‐experimental design to identify the effects of borrowing by men and women by using an original combination of panel data and instrumental variables on subsamples of the surveyed population. It finds that the borrower's gender affects how households allocate their resources to different expenditure items and assets that are valued differently by men and women. In all, the findings suggest that providing greater credit access to women may improve their household bargaining positions.     

Using choice experiments to estimate consumer valuation: the role of experimental design and attribute information loads

With fixed dimensionality of choice experiments (CEs), previous simulation results show that D‐optimal design with correct a priori information generates more accurate valuation. In the absence of a priori information, random designs and designs incorporate attribute interactions result in more precise valuation estimates. In this article, Monte Carlo simulations demonstrate that the performances of different design strategies are affected by attribute information loads in CEs. Consumer valuation estimates in simulation settings vary with the number of attributes.     

Deprived land-use intensification in shifting cultivation: the population pressure hypothesis revisited

This article provides a theoretical framework, based on optimal control theory, to analyze farm households' land‐use intensification decisions in forest‐based shifting cultivation (slash‐and‐burn) agroecosystems. The main results from the analysis generally coincide with the “Population Pressure Hypothesis” (PPH) as an important driver of soil degradation due to the so‐called “fallow crisis” or “deprived land‐use intensification” in shifting cultivation. However, the model also shows, from a supply perspective, that such a vicious circle of lower yields and greater forest land clearing may be avoided when the production elasticity of on‐farm labor outweighs the elasticity of substitution between farm labor and soil fertility. Furthermore, using data from shifting cultivating households from Yucatán, Mexico, we calibrate the effect of changes in population density. The numerical analysis suggests that by contrast to better‐off households, when population density increases, poorer shifting cultivating households' optimal labor allocation strategy is to further extensify land use by clearing more forest in the village common property land, or ejido land.     

Gender,control, and crop choice in northern Mozambique

Women play an important role in the agricultural production process in developing countries, yet their role in making decisions about what to grow and implications for household welfare remains poorly understood. In this article, I study women's empowerment in northern Mozambique as it relates to agriculture, considering in particular the factors associated with women managing the plots that they nominally control. Women control about 30% of the plots in the data, but only manage about 70% of those plots. Using a unique panel data set, I find that women are more likely to manage plots when households have had historic access to off‐farm labor, typically completed by men. When women manage plots, they tend to grow crops with less complicated production techniques and are less likely to grow the main area cash crop. However, conditional on historic access to off‐farm labor their farm incomes are the same as among men.     

Enhancing farmers’ capacity for botanical pesticide innovation through video-mediated learning in Bangladesh

Despite the general success of farmer-capacity-building methods such as Farmer Field School in promoting pest management innovations, only those farmers directly involved benefit. How can agricultural extension enable farmer-to-farmer learning about botanical pesticides beyond such schools? We wanted to know how different learning methods, such as video shows and workshops, change farmers’ knowledge, attitudes and practices about botanical pesticides. This paper explains how video engages men and women farmers in spreading botanical pesticides across 12 villages in Bogra District, north-western Bangladesh. We conducted ex ante and ex post surveys among farmers from November 2009 to September 2010. For data analysis, we used t-test and McNemer and Wilcoxon sign rank tests. Our findings suggest that video improves the ability of both male and female farmers to communicate about pest management among themselves and with other stakeholders, as ‘intricate ethno-agricultural practices’. Video-mediated learning sessions are more effective than conventional workshop training in enhancing farmers’ knowledge about botanical pesticides, changing their attitude and finally taking a decision to adopt these methods. In other words, video is capable of communicating complex issues such as the biological and physical processes that underlie pest management innovations. From our case, we conclude that agricultural extension is more effective with the use of facilitated video learning and that this process clarifies complex agro-ecological principles, bias and normative perceptions of the learners. Also, video-mediated learning is not only transferable across villages, but also works well in combination with other media, such as radio, television and mobile phones.

Policy Discourses on Women's Land Rights in Sub–Saharan Africa: The Implications of the Re–turn to the Customary

This article examines some contemporary policy discourses on land tenure reform in sub–Saharan Africa and their implications for women's interests in land. It demonstrates an emerging consensus among a range of influential policy institutions, lawyers and academics about the potential of so–called customary systems of land tenure to meet the needs of all land users and claimants. This consensus, which has arisen out of critiques of past attempts at land titling and registration, particularly in Kenya, is rooted in modernizing discourses and/or evolutionary theories of land tenure and embraces particular and contested understandings of customary law and legal pluralism. It has also fed into a wide–ranging critique of the failures of the post–colonial state in Africa, which has been important in the current retreat of the state under structural adjustment programmes. African women lawyers, a minority dissenting voice, are much more equivocal about trusting the customary, preferring instead to look to the State for laws to protect women's interests. We agree that there are considerable problems with so–called customary systems of land tenure and administration for achieving gender justice with respect to women's land claims. Insufficient attention is being paid to power relations in the countryside and their implications for social groups, such as women, who are not well positioned and represented in local level power structures. But considerable changes to political and legal practices and cultures will be needed before African states can begin to deliver gender justice with respect to land.     

Time preferences and commitment devices: evidence from ROSCAs and funeral groups in Benin

Drawing on first-hand data collected from a household survey in urban Benin, we examine membership in two types of informal groups that display the characteristics of a commitment device: Rotating Savings and Credit Associations (ROSCAs) and funeral groups. We investigate whether agents displaying time preferences with a present bias are more likely to commit themselves through participation in such groups. Our results provide evidence indicating that women who display such preferences are more likely to join funeral groups, but not ROSCAs, and to save more through them. These results hold for women but not for men. We also ensure that our results cannot be explained by intra-household conflict issues.     

Political reservation and female empowerment: evidence from Maharashtra,India

This paper studies the impact of political reservation for women on political participation and empowerment of women living in areas where gender quotas are mandated. Following the 1992 passage of the 73rd Constitutional Amendment in India, one-third of village government head positions are reserved for women. Utilizing the random allocation of reserved seats and a unique individual level data-set which captures a large set of measures on political participation of women, we find that women residing in areas with a female village government head show significantly higher levels of political participation and empowerment. Overall, the observed effect can be entirely attributed to improved outcomes of women from a lower socio-economic strata, while no effect is found for economically better-off women. The results suggest that the imposed gender quotas are an effective means of overcoming inequalities and contributed to giving disadvantaged women more voice and opportunity for political empowerment. We further investigate the role that the level of women’s political participation plays on the type and quality of public services delivered. Our results indicate that the level of women’s political participation and empowerment is an important channel through which public service delivery is influenced.     

Yield Effects of Tissue Culture Bananas in Kenya: Accounting for Selection Bias and the Role of Complementary Inputs

We analyse yield effects of tissue culture (TC) banana technology in the Kenyan small farm sector, using recent survey data and an endogenous switching regression approach. TC banana plantlets, which are free from pests and diseases, have been introduced in East Africa since the late 1990s. Although field experiments show significant yield advantages over traditional banana suckers, a rigorous assessment of impacts in farmers’ fields is still outstanding. A comparison of mean yield levels between TC adopters and non‐adopters in our sample shows no significant difference. However, we find evidence of negative selection bias, indicating that farmers with lower than average yields are more likely to adopt TC. Controlling for this bias results in a positive and significant TC net yield gain of 7%. We also find that TC technology is more knowledge intensive and more responsive to irrigation than traditional bananas. Simulations show that improving access to irrigation could lift TC productivity gains to above 20%. The analytical approach developed and applied here and the finding of negative selection bias may also be relevant for the evaluation of other agricultural technologies.     

Toward understanding household preference for consumption characteristics of millet varieties: a case study from western Niger

In this study, we evaluate the preference of consumers in Niger for different tuwo or couscous characteristics using a random utility‐based choice experiment, ordered probit analysis, and tree‐based partitioning. Data were collected through a structured survey administered at four sites. Preferences are estimated for three products (couscous, fermented tuwo, and nonfermented tuwo) made from five pearl millet cutivars. We provide relative valuation for different traits by type of product. Results show that product taste, color, and textural attributes are important, especially for tuwo and couscous. Probit and partitioning results show that taste and color are the first attributes that consumers use to distinguish more preferred millet food products from less preferred millet food products. This should provide some direction for millet breeding programs and food processing of millet.     

Information sharing as a safeguard against the opportunistic behavior of South African Karoo Lamb farmers

Misconduct in global meat supply chains are omnipresent and even more so in differentiated chains where credence attributes such as origin and taste are used to differentiate the product. By definition, these attributes signal asymmetric information which implies that in the presence of bounded rational individuals with conflicting interests, misconduct in the form of opportunistic behavior is bound to prevail. Increased information exchange through farmer networks is, however, expected to reduce opportunistic behavior. In the case of a differentiated meat product, such as Karoo Lamb, the article studies the farmer‐abattoir transaction with the purpose of recommending strategies that can be implemented to reduce the farmer's tendency to behave opportunistically. The article employs the PLS approach to SEM and reveals a significant negative relationship between information shared and opportunistic behavior. The results indicate significant positive relationships between trust in the abattoir and information shared as well as between farmer networks and information shared. These results are indicative of the support provided to the information shared construct by higher levels of trust between farmers and abattoirs and established farmer networks. It is, therefore, recommended that differentiated meat supply chains, through their various associations, concentrate their efforts to promote information sharing by building stronger, trust centered relationships and by supporting farmer networks.
