To orient the commercial development of cowpeas, we identify the determinants of the value of cowpea grain sold by traders in Senegal’s local markets. We test whether the determinants differ between men and women traders and explore seasonal patterns.

We employ ordinary least squares and seemingly unrelated regressions using a nationally representative dataset of 973 traders, of whom 380 sell cowpea grain, in 99 urban and rural markets across the 14 regions of Senegal.

The value of cowpea grain sold is influenced by vendor and market characteristics but not by cowpea type. Women and men traders represent statistically distinct groups. The sales value was eight times higher during the survey season among men. Most women grain sellers are retailers, whereas men are involved in both retailing and wholesaling. The picture that emerges is that men traders are able to respond more to economic signals, such as purchase cost, credit and labor payments, perhaps because they operate on a larger scale. Sales were significantly correlated across seasons.

To support cowpea commercialization, researchers should explore the characteristics of enterprises led by women and men traders in greater depth. Sampling grain sold in markets to test genetic relationships with improved varieties would enable researchers to link market-based incentives directly to cowpea breeding.

Previous economics research about cowpea grain markets emphasized the hedonic analysis of grain characteristics to guide crop improvement. This study reveals differentiation among traders by gender and the importance of trader and market characteristics in sales value.

The authors assess the development potential of cowpea beyond grain in local markets in Mali by: (1) identifying trader types and types of cowpea products sold; (2) examining trader roles; (3) estimating gross margins and their determinants; and (4) discussing policy opportunities to further develop the value chain.

The authors analyze data collected through observation and semi-structured questionnaires from 487 sellers in 26 markets, including market, seller, and product characteristics. The authors also calculate gross margins and conduct a regression analysis to identify influential factors.

The authors identify several types of cowpea sellers in local markets, including processor-retailers, retailers of fresh leaves and fodder, and grain retailers, collectors and wholesalers. Women dominate the marketing of processed products and fresh leaves. The marketing of boiled cowpeas offers retailers higher margin rates compared to fritters and pancakes. Grain sellers, who are mostly men, have lower margins but sell larger quantities. Processor-retailers bring more value to the cowpea value chain. Specialization of the seller in cowpea, regional location of the market and day of the market fair all influence gross margins.

Future work should explore consumer preferences for different types of cowpea products.

This study of the cowpea value chain in Mali has revealed the multidimensional character of the cowpea plant, which goes far beyond its grain and highlight the important roles played by women.

Scientists in Pakistan are currently developing biofortified wheat varieties to address widespread zinc deficiency, especially among women and children in poorer rural households. The purpose of this paper is to understand how the productivity and efficiency of small-scale and marginal wheat farmers can be improved so that their households may benefit from zinc-fortified varieties.

The authors estimate a stochastic frontier production function model with data from a survey of wheat farmers conducted in Punjab, Pakistan in 2011.

The productivities of the newer varieties of wheat were significantly greater than the older varieties, as expected. Farmers growing wheat in the rice-wheat and cotton-wheat zones tend to be more efficient than farmers from the mixed zone. Farmers who wait to adopt a leading variety are not less efficient than earlier adopters, but the longer the time until they switch varieties again, the more inefficient is their wheat production. Older farmers tend to be more technically inefficient than younger farmers, but the effect of education is not statistically significant. Wheat farmers with access to extension advice are more efficient. Farmers whose land suffered from severe salinity or severe toxicity are less productive and less efficient than others.

The authors find no differences in technical inefficiency effects associated with growing the four most popular varieties, either grown alone or with other varieties – suggesting that no single leading variety should be targeted for biofortification. In contrast to some earlier studies, the authors find that small-scale farmers tend to be less technically efficient. This result underscores the need to specifically target this group in promotional programs, and also to complement these with reinforcement of agronomic recommendations.

This project is part of the HarvestPlus program to determine the appropriate variety or varieties to biofortify with zinc so that Pakistan’s population can have better health and well-being. Further, the results show that there it is desirable to undertake further studies to improve the productivity and efficiency of wheat farmers in the Punjab, Pakistan to increase the health and well-being of the population in general.

How should a multinational corporation (MNC) from a mature democracy deal with the human rights issues in a country with a poor human rights standard? The paper aims to discuss these issues.

The authors develop a mathematical model to depict MNC's behavior in response to human rights violations in the host country.

The authors show that, first, in a country with a high level of human rights abuses, a firm will have to lower its human rights standards to survive; but, second, a collective effort by all firms is essential to improve the human rights conditions in the host environment; and third, a firm's human rights practices may have a multiplicative effect that can significantly affect the momentum of human rights development in a host country.

This study is one of the first attempts to provide a theoretical framework on the issue of MNCs and human rights in host countries.

The purpose of this paper is critically examine the Nigeria for Women Project (NFWP) initiatives in Nigeria. Its special focus is to investigate the impact of NFWP on social cohesion in entrepreneurship development in Nigeria.

This paper adopts a quasi-experimental research design to address the scarcity of quantitative studies on women’s groups in Nigeria. A total of 2,400 respondents were sampled across the rural areas of the six geographical regions of the country.

Results from the use of a combined propensity score matching and logit model indicate that though scrimpy, the NFWP intervention targeted specifically for the empowerment of women, using the women’s affinity group model has recorded significant set up in improving women’s formation of social capital through advocacy, awareness creation, provision of credit, training of women on skill acquisition, among other activities.

This suggests that an increase in NFWP budget that seeks to expand participation of women in women’s groups, targeted at increasing women’s social cohesion, especially in the rural communities will help lift women and girls out of poverty in the country.

It implies that women’s groups that serve as production cooperatives, saving associations and marketing groups can enhance women’s performance in entrepreneurship development and boost rural economy production in Nigeria.

This research contributes to the growing field of female entrepreneurial collaboration by proposing the moderation of social cohesion as a means to sustain agriculture and rural development in developing countries. It concludes that targeting women’s groups should form the foundation of public policy for social cohesion in women’s entrepreneurship development for rural economy.
