Most of the literature on vertical coordination and its impact on farm performance and farmer wellbeing deal with high-value or modern food supply chains, including export chains and chains dominated by large international supermarkets or other forms of foreign direct investment. The impact of vertical coordination mechanisms in local food supply chains in developing countries remains underexplored. This paper analyzes the impact of participation of honey producers in the Northern highlands of Tigray, Ethiopia in contracts and marketing cooperatives on their performance and wellbeing. The paper finds positive production and economic gains honey producers obtain from contract engagement. Honey producers under the contract scheme produce more white honey fulfilling the demand of processors, buyers and consumers. Contracting results in higher production due to the better access it causes to technology and skill transfers. Moreover, better conditions contracts offer motivates honey producers to produce more and supply larger to the market.
The transformation of agricultural marketing systems in sub-Saharan Africa remains slow, even after the liberalization and globalization of trade. The rural agricultural marketing system in developing countries fails to adjust and fully respond to changes in the market in terms of quality and quantity (Jayne et al., 2010). As in many countries and regions in sub-Saharan Africa, the marketing system in the rural highlands of Ethiopia does not perform well due to several challenges (Gabre-Madhin, 2001).
The poor economic conditions, the imperfect input and product markets, the large number of smallholders, the high transaction costs in searching buyers, the lack of private sector investment in processing and agri-business and the poor coordination among actors in the agrifood supply chain are cited as the factors that restrain the performance of food supply chains in developing countries (Dorward et al., 22007; Gabre-Madhin, 2001). Institutions for market information, standardizing, grading and labeling, and contract enforcement are also weak, which further undermines the performance of the agricultural marketing system. Poor road and communication infrastructure, thin input and output markets, underdeveloped monetary systems are further claimed to affect the rural areas in Africa (Dorward et al., 2007).
Theory and empirical evidence suggest that vertical coordination (VC) can foster the development of smallholder agriculture through the provision of inputs and technology, and the mitigation of transaction costs (Williamson, 1979; Swinnen and Maertens, 2007). Empirical evidence from Eastern Europe, Africa and Latin-America suggests that contracts offer credit, inputs, better prices and extension services which enable growers to be productive and secure better economic benefits (e.g., Minten et al., 2007; Dries et al., 2009; Maertens et al., 2011). Also cooperatives can facilitate the access of smallholder farmers to farm resources, especially for poor farmers. They facilitate access to credit and reap the benefit of significant support from state and other development partners (Key and Runsten, 1999; Bijman and Hu, 2011). Cooperatives can also help empower farmers in terms of collective ownership of farm investment and processing technology (Hendrikse and Bijman, 2002). Marketing cooperatives are also found influencing smallholders’ commercialization behavior in Ethiopia and having poverty impact in Rwanda though the results indicate better benefits to larger farmers (Bernard et al. 2008; Francesconi and Nico 2010; Verhofstadt and Maertens, 2014).
Researchers and policy-makers are optimistic about the observed increased VC in food supply chains as it can contribute to the transformation of traditional agricultural practices towards modern supply chains (Abebaw and Haile, 2013). However, the impact of VC on the performance of smallholder farms remains controversial. Empirical evidence from organic coffee producers in Uganda, tomato producers in Senegal, and apple and green onion producers in China have indicated positive income gains of contract-farming (Maertens and Swinnen, 2009; Miyata et al., 2009; Bolwig et al., 2010). The observed increase in smallholders’ income is attributed to buyers’ commitment for the supply of inputs, technology and extension services; which enables farmers to increase productivity. In China and Uganda farmers under a contracting scheme were found to be efficient as they received extension skills to manage inputs, feed, labor, and capital (Miyata et al., 2009; Bolwig et al. 2010). Furthermore, contract farming leads to better quality produce and premium prices, resulting in larger economic benefits for farmers. Contracting also may reduce transaction costs, and leads to more efficient transactions in food supply chains (Miyata et al., 2009). Furthermore, contracts may channel capital/financial support to farmers to ease expansion of firms (Simmons et al., 2005; Dries et al., 2009). Spillover effects may also contribute to the productivity of smallholder farmers in various developing countries (Schipmann and Qaim, 2010).
In cases where farmers fail to access contracts due to their small size, processors and rural development agencies sometimes supply credit and inputs via cooperatives (Abebaw and Haile 2013; Bernard et al., 2008). Cooperatives or farmers’ organizations generally pool resources to facilitate access to specific assets, reduce information asymmetries, empower smallholders in the market, and facilitate organized support from credit and technology suppliers (Bernard et al., 2008; Bijman and Hendrikse, 2003; Bijman and Hu, 2011; Blandon et al., 2009). Cooperatives also lower transactions costs for providing extension services and information (Masakure and Henson, 2005), and facilitate the adoption of new technologies (Nwankwo et al., 2009; Abebaw and Haile 2013).
Despite its wide application in developing countries, contracts are sometimes criticized for exploiting farmers (Singh, 2002). Unequal power relations between contractors and contracted producers can lead to contract conditions in favor of large-scale companies and to the exploitation of farmers. Furthermore, contracts are also accused of eroding the autonomy/flexibility of farmers in making farm decisions (Gillespie and Eidman, 1998; Key, 2004). A much debated issue is the exclusion of the poorest farmers and the smallest farms from contract farming schemes. High administrative costs of contracting with a large number of small producers foster contracting with larger farms. Asset-poor farmers may face difficulties in complying with processor/retailer specific standards and requirements, resulting in the exclusion of poor farmers from contract-farming schemes (Weatherspoon and Reardon, 2003). However, producer-induced organizations such as cooperatives help tackle the exclusion of smallholders and offer significant economic benefits to smallholders (Staal et al., 1997; Takane, 2004; Bijman and Hu, 2011).
Most of the literature on VC and its impact on farm performance and farmer wellbeing deals with so-called high-value or modern food supply chains, including export chains and chains dominated by large international supermarkets or other forms of foreign direct investment. The impact of VC mechanisms (contracts and marketing cooperatives altogether in contrast to spot markets) in local food supply chains in developing countries especially in the Ethiopian context remains underexplored though the challenges in the traditional domestic markets in the African context are well studied (Dorward et al., 2006). Comparative studies on the impact of hybrids, contracts and marketing cooperatives viz. spot market transactions are scare. In this paper, we analyze the impact of participation of honey producers in the Northern highlands of Ethiopia in contracts and cooperatives on their performance and household income. We, thus contribute to the literature on VC by providing evidence from local food chains and provide insights that can inform governmental and development organizations on the realization of pro-poor growth through institutional innovations such as contracts and marketing cooperatives in supply chains in partnership with the private sector.
The practice of beekeeping in Ethiopia is integrated with crop farming and animal husbandry at household level. It is part of the integrated household extension program targeted to diversify household livelihood and income (Egziabher et al. 2013; Legesse, 2014). CSA (2013) reported that there were nearly 5.21 million beehives in Ethiopia, producing 45,100 tons of honey, of which about 38 % was for household consumption, 58 % for the market and the rest for wage payment. Production of honey grows every year; for eg. It grows from 24,000 tons in 1993 to 45,100 tons in 2012. In terms of honey production, the country is ranked 9th in the world which may offer an advantage to capitalize on the subsector (FAO 2015). Honey export has increased from 1.5 tons in 2000, 275 tons in 2010 and more than 730 tons in 2012 (Legesse, 2014). Honey production and marketing in Ethiopia is largely at household level and on spot market bases. However recently, production cooperatives, marketing cooperatives and contract base transactions in the honey subsector are emerging to offer producers with required inputs, technology, market information and market access thereby reducing transaction costs. However, this paper is limited to the impact of contracts and marketing cooperatives on the income of honey producing households in Tigray, Northern Ethiopia.
The rest of the paper is organized as follows. In section two the honey production and marketing system in Ethiopia is briefly reviewed. In the third section the study site is presented and data collection procedures are explained. In the fourth section the coordination mechanisms and performance of honey producers are discussed based on descriptive statistics. The econometric methods and estimation procedures are explained in the fifth section, and econometric results are discussed in the sixth section. The last section ends the paper with conclusions and implications.
Honey Production and Marketing in Ethiopia and Tigray
Honey production has a long tradition in Ethiopia. The practice of beekeeping in Ethiopia is often integrated with crop farming and animal husbandry. In many regions of the country, beekeeping is an important additional income-generating activity for farmers, next to cropping and livestock rearing. Currently, the honey sector is part of the integrated household extension program runn by the government to imprve productivity and increase household income (Egziabher et al. 2013). It is also believed to be one of the subsectors which tend to be inclusive of smallholders in Ethiopia (Paulos, 2012). Apiculture can importantly contribute to the livelihood of rural households, either by providing additional income through honey sale or by providing a high-nutritious food product for household consumption. Honey production is regarded as a poverty reduction strategy and as a tool for combating malnutrition in rural areas of developing countries (Legesse, 2014).
The honey production has grown almost every year from 24,000 tons in 1993 to 45,000 tons in 2013 (FAO, 2015). Most honey (more than 95 %) is produced using traditional beehives. However, traditional beehives produce less than 10 kg of honey/hive/year. The modern beehive provides on average 23 kg of clean honey per hive/year (CSA, 2013). However, modern hives are costly (on average USD 50.00) compared to the locally made traditional hives that costs no more than USD 5.00. CSA (2013) estimated that 38.31 % was for household consumption, 58.49 % was for the market largely for domestic market (more than 98 %) and the rest was used as wage payment. Most of the honey production is carried out by smallholder farmers. It has a prospect of further growth if it is well integrated with the global food chains and supported with relevant inputs and technology. Nearly 4.4 % of the beehives are found in Tigray which accounts for 5.2 % of the total honey production in Ethiopia (CSA 2013). More than 20 % were modern beehives implying more modern beehive technology use in the region (CSA 2013) and the majority of honey is offered to the market (more than 60 %).
There is an increasing trend in the production of honey from modern beehives. Modern beehives and honey extracting technology are mostly supplied by government agencies and non-governmental organizations (e.g., ARDO, REST-local NGO which stands for Relief Society of Tigray, World Vision, the Ethiopian Orthodox and the Catholic Church). For example, in 2008 the Regional Agricultural and Rural Development Office (ARDO) provided 26,676 units of modern beehives to smallholders in Tigray.
Honey export was below 1 % of production up until 2006. However, once the government and development partners have aggressively distributed modern hives, processing companies has acquired more honey supply and expand honey export. The honey export increased from one ton in 2001 to 615 tons in 2010 and 729 tons in 2013. It is destined mainly to Yemen, Sudan, Saudi Arabia and Djibouti before getting the admisiion to penetrate the EU market in 2008 (Gezahegn et al. 2006; Paulos 2012).
The 2010 estimate of honey production in Tigray was 2,768 tons, which accounts for 5.2 % of the total honey production in Ethiopia (CSA, 2013). There were 213,133 beehives in Tigray in 2010. More than 20 % were modern beehives (CSA, 2013) and the majority of honey is offered to the market (more than 60 %). As reported by Melaku et al. (2008), 80 to 90 % of the honey produced in the Atsbi district was marketed, which points to the market-oriented nature of honey production in the region. There is an increasing trend in the production of honey from modern beehives; i.e., 269 tons in 2005 to 1061 tons in 2010. ARDO, NGOs and processors contribute to the expansion of modern beehives in the region.
Most of the honey produced and marketed in Tigray is white honey, while only a small amount of yellow and red honey is produced and marketed. White honey is high value honey that is harvested during the prime season (September to December) and almost entirely sold by farmers. During the dry season, farmers may harvest some honey, but due to the scarcity of flowers and plants, bees mix species result in a change in color for the honey. Part of the yellow and red honey is being kept at home for consumption or medicinal use (Gezahegn et al. 2006; Melaku et al., 2008). To improve honey production and marketing, government and NGOs (like World Vision, SNV-Ethiopia, REST) have intervened to upgrade beehives and extraction process, transfer technology through training and supplying credit and inputs.
As production of honey is largely in the hands of smallholders who own only a few beehives, it offers a small amount to the market from which the majority (about 80 %) is supplied to local mead brewers (Gezahegn et al. 2006; Melaku et al., 2008). The subsector is also facing a number of challenges such as lack of adequate technology, extension services, beekeeping materials and lack of adequate market (Abebe and Ranjitha, 2011).
Nevertheless, to improve honey production and the marketing system in the country, government and other non-governmental development organizations (like World Vision, SNV-Ethiopia, REST) have intervened to a great extent in terms of modernizing the beehives and the extraction process, transferring technology through training, upgrading the honey value chains, and supplying credit and other inputs (Paulos 2012).
Honey is marketed mostly on spot markets, either by selling it directly to consumers or by selling it to buyers (mead houses or retailers). Contracts between farmers and buyers (retailers, mead houses) or processors are scarce and largely oral. Only the private processing company Dimma employs written contracts to obtain honey from farmers or cooperatives. The obligation of the supplier (honey producer) includes the supply of a specified amount of honey with a specified quality and delivery date to Dimma. The contract also stipulates the obligations of Dimma including paying a fixed price per kilogram during the time of delivery and delivering honey at a specified place (producers place) by sending their own procurement experts. Dimma has signed contracts with marketing cooperatives listing the name of each member in the contract. The contract also stipulates the modern beehive, extractors, smokers and honey containers provided to the marketing cooperatives. The agreements also specify conditions to terminate the contract but any of the contracting party is required to inform ahead of time (1 month earlier).
Formal cooperative establishment in ethiopia dates back to 1960. Since then further expansion and declarations have been in place. Thre was a new proclamation by the Federal Democratic Republic of Ethiopia (FDRE) in 2002 and establish Federal Cooperative Agency to organize and promote cooperatives at national level. Different types of cooperatives are established in diffecent rural hillages (kebeles) throughout the nation: producer cooperatives, marketing cooperatives, multipurpose cooperatives, consumers’ cooperatives (Bernard et al., 2008; Emana, 2009; Bernard and Alemayehu 2008).
With regard to cooperatives in Tigray, The survey conducted by the Agricultural Transformation Agency of Ethiopia has indicated that there were no cooperatives before 1991 (Bernard et al. 2008). Farmer cooperatives in the honey sector were launched once private beekeeping and honey processing company (Dimma) transferred its own apiary sites to selected farmers who were living closer to the apiary sites. These cooperatives are operating in the production and marketing of honey. Farmer cooperatives possess common apiary sites and individual beehives and obligate members to commit themselves to take care of apiary cites. They also have common processing technology such as honey extractors, masks and smokers that are provided by government or other development partners (e.g. ARDO, REST, and World Vision). The marketing cooperatives not only collect honey from farmers but provide different processing technology to honey producers. They also facilitate access to credit to acquire modern beehives for their members. These cooperatives also supply honey for the other processing companies (Wukiro Mar and Wolela Mar) that are operating at small-scale level.
Cooperatives established in Tigray are multipurpose cooperatives, marketing cooperatives, producer cooperatives and credit and saving cooperatives. Honey producers are memebrs of marketing cooperatives to supply honey to buyers specifically to Dimma beekeeping and honey processing. They also supplied honey for Wukiro Mar and Wolela Mar though they raise the issue of traceability problem while getting supply from marketing cooperatives. For this study, those members of honey marketing cooperatives are considered.
We apply a case study approach, using data from the Geba catchment in the Tigray region in northern Ethiopia. This area was chosen as a focus site for a large collaborative and interdisciplinary research project which this study is part of.
The situation concerning beehive ownership and honey production in the northern highlands of Ethiopia is similar to the rest of the country. Most rural households possess traditional and modern beehives and produce small amounts of honey for the market and for household consumption, next to a range of other farm and non-farm activities. The number of traditional and modern beehives in Tigray is estimated to be 229,629 (61,311 modern and transitional, 168,315 traditional) and total honey production 3,272 tons, constituting 5 % of the national production (CSA, 2013).
Large volumes of honey are produced from traditional beehives and traditional extraction systems. These traditional systems often fail to meet processors’ quality requirements. Due to intensive intervention by the government and by development partners, a shift from traditional to modern beehives is ongoing. This modernization has resulted in increased honey production and increased market supply stimulating producers and government to establish marketing cooperatives to empower producers in the market. Honey producers are increasingly seeking for better and more secure market outlets through contracts and cooperatives. In addition, the problem of adulteration and poor harvesting practices makes it difficult for processors to source sufficient volumes of good quality honey, which drives them to contract with individual honey producers and marketing cooperatives and offer extension services as part of the contracts.
A household survey was organized in the case study area in the period April-May 2010. As the aim of the study is to evaluate the different coordination mechanisms in the honey supply chain, honey producers possessing modern beehives who are registered by the rural development office were purposively selected. These households are selected expecting that they offer surplus honey to the market as they exploit modern technology. In the first stage of the sampling design, four districts (woredas) were selected out of a total of 10 districts in the Geba catchment area. The districts with the largest beekeeping households and with actual and potential surplus honey production were selected. These districts were identified in consultation with the district livestock experts in the Rural Development Office (RDO).

Coordination mechanisms and performance of honey producers
Honey producers in the case study area are involved in three different types of marketing coordination arrangements, including spot market transactions (81 % of sampled producers), contract arrangements (12.5 %) and marketing cooperative arrangements (6.5 %). Some contract producers also sell honey through spot market arrangements. Cooperatives usually restrict member farmers not to participate in other types of transactions. Side selling by members usually involves disciplinary actions such as cancellation of membership. Those who are expelled from membership are devoid of access to modern hives on creditwhich are provided through cooperatives.

Comparing the number of current modern beehives possession from what they had 5 years ago, the figures in Table 3 show that there has been an increase in the average number of modern beehives for all types of producers. Almost half of the farmers in the sample, 49 %, have at least one modern hive. This increase is partially the result of government and NGO interventions to supply modern hive technology, training and extension to enhance honey production and quality, as part of a poverty-reduction strategy. Different projects, e.g. ARDO (credit from Dedebit Credit and Saving Institution and other development partners), the Myzegzeg project, World Vision, the Catholic Church and the Ethiopian Orthodox Tewahido Church, provided modern beehives and technology to farmers and 35 % of honey producers in the sample received modern technology through this channel. The Dimma Honey Processing Company also provides beehives to honey producers and cooperative members committing to supply honey to the company; this is the case for 3 % of producers in the sample. Some producers bought modern beehives themselves or received them from other buyers.
Honey producers in the districts report the receipt of extension services to improve honey quality which include the provision of modern hives, training on honey extraction and quality standards, and the provision of equipment such as smokers and masks. Thirty percent of the honey producers operating in spot markets and 28.6 % of the cooperative members and 17 % of contract participants did not make further investment on buying modern hives and technology to improve quality. Twenty percent of the contract participants obtained credit and technology support from processors and buyers. A large part of the cooperative members and contract producers indicates that honey sales and incomes are increasing from year to year. However, nearly 31 % of the spot market producers say their honey sales go down.
The descriptive statistics presented in the previous section indicates that honey producers who market their produce through contracts have more modern beehives, a higher total and per hive honey production, and a higher income in total and from beekeeping specifically. However, based on a simple comparison of averages across honey producers in different coordination channels, it is impossible to identify causality. To reveal whether the observed differences in performance between contract producers, cooperative producers and spot-market producers are attributable to the different coordination channels, a more profound econometric analysis is needed.
We look at five different outcome variables Y: (1) hive productivity (kg), (2) honey production (kg), (3) honey income (birr), (4) total household income (birr), and (5) per capita household income (birr) and these variables are log-specified in the model. The variables C1 and C2 represent the different coordination mechanism, contracts and cooperatives respectively. These are the main variables of interest and the coefficients γ1 and γ2 are referred to as the treatment effects of contracts and cooperatives respectively. The vector X includes a large set of observable covariates to correct for potential bias due to selection on observables: village dummy, distance to RDO, distance to asphalt road, land size, number of beehives, number of children, education, age, and household size. This model is estimated using Ordinary Least Squares (OLS) estimation.
Two different matching procedures are used. Nearest neighbor matching, in which every treated household is matched to the control household with the closest propensity score. This is the most commonly applied matching algorithm in propensity score matching estimation (Ichino et al., 2008). It is complemented with a kernel matching technique, in which information from all control observations is used to compute the Average Treatment Effect (ATE) estimate (Caliendo and Sabine 2005). For kernel matching the biweight kernel type and the default bandwidth in STATA (0.06) are used. Matching is always done with replacement and only observations in the common support region – where the propensity score of the control units is not smaller than the minimum propensity score of the treated units and the propensity score of the treated units not larger than the maximum propensity score of the control units – are used in the analysis. As propensity score matching methods are sensitive to the exact specification and matching method, the use of different matching techniques serves as a robustness check.
These assumptions are addressed after the discussion of the results.

On the one hand, the econometric results confirm that participating in contracts results in significantly higher hive productivity, higher total honey production, and higher producer incomes. Taking the most conservative estimates, we find that contract production increases the productivity of modern beehives by 37 % and the total annual amount of production of honey with 76 %. In addition, income from honey production increases with 85 %, total household income with 28 % and per capita income with 31 % if honey is produced under contract. These are large and important effects, which show that contract farming and the technology transfers and reduced transaction costs that contracting entails, can be a tool for income growth in rural areas of developing countries. Our results show that the positive effects of contract farming on productivity and producer income that previous studies showed for high-value crops and export-oriented food chains (e.g. Key and McBride 2003; Maertens and Swinnen, 2009; Maertens et al., 2011; Miyata et al., 2009) also hold for lower-value produce and local food chains.

We can conclude that contracts offer better opportunities to honey producers than cooperatives. Contracts facilitate the acquisition of technology and inputs and result in better market conditions. They facilitate closer communication between producers and contractors (processors or retailers), and reduce transaction costs in multiple ways. While cooperatives also entail the potential to reduce transaction costs and result in better market conditions, in the honey sector in Tigray they are not successful in doing so, likely because of problems with management and incentives of producers.
In Table 5 the full regression results are given for the regression on covariates and the regression on propensity scores for total household income as dependent variable. The results indicate that apart from contract participation, other factors influence honey production and income as well. We find that the location of households matters. Households in the Ofla district have a significantly higher income than households in other districts. We find a negative effect of age but a positive effect of producer experience on household income. Further, labor endowments and productive assets determine household income. We find that a higher number of active household members, more livestock, and more beehives increase income of the households.
Estimating the propensity scores
The results of the bivariate probit model estimating the propensity scores are given in Table 6. These results indicate that the age of the household head, the size of the land and distance to an asphalt road influence the probability of producers to engage in contracting while household size, number of livestock units, number of traditional hives and distance to asphalt road influence the probability to engage in cooperatives.

This paper identified three basic marketing channels farmers employed to supply honey. The paper also identified an increased use of modern beehives across honey producers. Contracting honey producers are shown with a relatively large number of modern beehives and they get transformed fast. Input and technology supply is largely from ARDO but some buyers, processors, and other religious and development institutions also participate in the provision of modern hives and extracting technology to honey producers.
We indicated the positive production and economic gains honey producers obtain from contract engagement. Honey producers under the contract scheme produce more white honey fulfilling the demand of processors, buyers and consumers. Contracting results in higher production due to the better access it causes to technology and skill transfers. Moreover, better conditions contracts offer motivates honey producers to produce more to the market.
As the findings imply, contract farming is found offering improved incomes to the honey producers which complement the existing literature on contract farming. It however does not find any evidence in support of honey cooperatives to supplement household income. This may entail that the effectiveness of vertical coordination mechanisms is product specific.
It is inferred from the study that contracting offers resources and better market conditions and we suggest that facilitating conditions that favor contracting in rural Tigray may be considered to upgrade the honey supply chain. Strengthening enforcement and standardizing institutions to facilitate contracting in the region may be considered an option to improve the honey supply chain and the household income. Minimizing the act of farmers to side sell by offering flexible and market based agreements may also tighten the linkages of honey producers with contractors.
Though changes have been realized in the modern hive use among cooperative members, production and economic gains do not seem different from the situations of the spot market users. As supplemented by the discussions with cooperative leaders, members lack commitment to spend their time on the apiary site and there has been a tendency of free riding (leaving the work to others). Traceability problems also affect the revenue cooperatives could generate from what they made available in the market. Many of the honey producing cooperatives under the study sites are not properly functioning and they are in the process of reestablishment. Cooperative formation has been seen by members as a simple source of modern beehives and credit, and members’ lower commitment to get their shares from dissolution.
The nature of the production system may also lend itself to the poor performance of cooperatives. Traditionally, beehives are placed within homes or backyards promoting individual commitment. However, cooperatives are given apiary sites demanding frequent visit and follow up to which many of the members fail to commit. In addition, lack of space and pesticide use around the apiary sites were reported to be the reasons impeding hive productivity. In sum, contracting is found to be instrumental for improving honey production, sales and income. However, care must be taken in interpreting the result as contract and cooperative participants are small in number. Conducting the survey at larger scale may be relevant to develop the complete picture on the contributions of contracts to honey production and producers’ welfare in Ethiopia. As such types of studies are scarce, it is difficult to have a benchmark to compare the marginal yield and the welfare effect of contract participation. It is then believed that it may serve as a good reference for similar studies in the future.
This is the case because cooperative members are obliged to sell the entire marketable output to the cooperative and hence cannot engage in other marketing channels.
