Farm households in Africa must cope with bad conditions as to soil quality, weather and infrastructure. The variability of rainfall causes yields to vary strongly from one year to the next. With yields already low (due to poor soil condition) these variations can be life threatening. Meanwhile, inadequate infrastructure makes it difficult to help the households with access to financial services, insurance and inputs that could stabilize their access to resources, and enhance yields.
Solving a single aspect, say bringing inputs to the farm, will not be sufficient as credit is also needed. But credit can only be provided if sufficient likelihood exists that loans will be repaid. Here, insurance can help. If insurance of the loan makes it attractive enough for the lender, a package can be composed of inputs, with credit and insurance, that solves all these problems with one bundle. Yet, the households will remain exposed to some risks as insuring against all is prohibitively expensive. What is the appropriate degree of insurance in such bundles? That is the core question addressed in this research. It aims at supplying inputs to farmers on credit, with insurance, in such a way that a good balance is found between the benefits and risks to the farmers and the profits and risks to the credit provider.
We investigate the possibilities for such a balanced approach in Kenya and Ethiopia in collaboration with a large insurance provider and a farmers organisation. Together with them we collect information on the costs, benefits and risks involved in using the inputs, the alternatives open to them, and the costs and benefits involved in providing credit to finance the purchase of inputs, with and without an insurance against crop failure.
With all this information, we go and talk to the stakeholders concerned to find out how they would respond if more or less insurance would be provided. Will credit suppliers lower their prices, if repayment of loan is more likely because the crop is insured? Will households decide to take higher yielding (but more risky) crops if part of the downside risk is insured? We establish this for the parties concerned in Kenya and Ethiopia, but also in other African countries.
Having established how these stakeholders respond to changes in insurance, we can proceed to derive what the best degree of insurance might be. And this is then finally tested in a field experiment.
With this knowledge we can help other suppliers of insurance and credit, and farm organisations to establish similar packages that are adapted to the local conditions for input supply, and financial services.
Data description (abstract)
We employ a discrete choice experiment to elicit demand and supply side preferences for insurance-linked credit and explore heterogeneity in these preferences using primary data from smallholder farmers and managers of financial institutions combined with household socio-economic survey data in Kenya. Bundling insurance with credit has emerged as a promising market-based tool for both managing agricultural weather risks and providing access to credit to farmers. However, to develop a suitable bundled credit product it is essential to tailor the product to the needs and preferences of both smallholder farmers and insurance and credit providers. We analyse the choice data using multinomial logit and Hierarchical Bayes estimation of mixed logit model. We find that farmers prefer credit for both seasons, credit term to be one year or longer, no or partial collateral for loan, lower risk premium, and loans to be used for any purpose. Supply side results suggest that managers of financial institutions prefer the risk premium to be added with loan amount, loans to be repaid after harvest, credit available for both seasons, credit term to be shorter than one year, loans to be used only for agricultural purpose, and loans to be fully or partially collateralised. We also analyse willingness to purchase and willingness to offer for farmers and suppliers, respectively for risk premium at different attributes and their levels. Identifying the preferred attributes and levels for both farmers and financial institutions can guide optimal packaging of insurance and credit providing market participation and adoption motivation for insurance-bundled credit product.

Our research team came up with nine attributes for the choice experiment that are thought to be the most important characteristics that a consumer and a supplier would look for. The attributes are insurance cost, insurance payment, insured risk coverage, credit term, collateral requirement, loan repayment flexibility, loan use flexibility, preferred season for loan, and rainfall measurement. Insurance cost or risk premium was included to allow for estimation of money metric measure of willingness to purchase for farmers and willingness to offer for finance providers. We specified four premium levels in our choice sets based on actually fair premium pricing. Regarding insurance payment attribute, actuarial design team and bank and insurance company representatives highlighted the option of premium to be added to loan amount and paying premium separately. Insurance risk coverage is directly related to cost of insurance, we define low coverage as insurance providing payout once in every 20 years, medium coverage as providing payout in every 10 years, and high coverage as covering frequent risk allowing payout in every 4 years. Credit terms are defined as six months (maize being a six-month crop in the area), one year and more than one year. As collateral is very important component of any credit lending in Kenya, we included partial, full and no collateral options. Loan repayment option of monthly and after harvest came clearly during our focus group discussions. Regarding loan use term, two options were included, loans can be used for any purpose versus loans can only be used for agricultural production. Since the area have two distinct seasons with bimodal rainfall pattern we included long, short and both seasons options. Finally, we included an option to elicit opinions about rainfall measurement for pricing and payout decisions. The rainfall calculation should be based on total rainfall shortage in season or shortage at each growth cycle of maize crop. This variable indirectly captures spatial basis risk option where rainfall shortage at crop growth cycle will have much lower basis risk compared to rainfall shortage in a season. |

To construct choice sets, we specified D-Optimality criterion using Federov search algorithm which is based on calculating the determinant of variance-covariance matrix of the parameters from non-linear logit model. Choice sets were constructed with three alternatives available for respondents to choose.
We need at least 24-9+1= 16 parameters to estimate. Also, we would want to take into consideration some interaction effects in addition to the main effects. This increases the number of parameters that we will want to efficiently estimate, which has implications for the number of runs as well as our sample size. A common rule of thumb is that the minimum sample size should be ,where S is the number of choice tasks presented to each respondent (9, in our case), J is the number of alternatives per choice task (3 in our case), and is the largest number of levels of any of the attributes (4, for insurance cost). Therefore, based on this, we should have at least 75 individuals in our sample.
The values of S and J can be determined exogenously but should satisfy the rank condition S(J-1)>K, where K is the number of parameters to be estimated. Estimating only main effects can buy us lower values for S and J, but this precludes any consideration of correlated or heterogeneous preferences. With the full set of interactions, the rank condition would be violated. In addition to problems with estimability, it also becomes increasingly difficult to get a suitable experimental design. We are certainly better off with three alternatives per choice set with each respondent replying to nine choice sets to satisfy rank condition.
In order to ensure data reliability, we placed special emphasis on increasing farmers’ understanding of and involvement in tasks. Thus, we included pictorial illustrations of the product attributes and levels in the choice cards to facilitate respondents’ choice task (see Figure 4). Also, to reduce participants’ possible fatigue, we grouped the choice sets into six groups of nine choice sets each. The participants were then randomly assigned to the choice sets presented in one of the six groups, with equal proportion of respondents allocated to each of the groups.
Additionally, we used partial profile designs as opposed to full profiles. In other words, we asked participants to respond to half the attributes (partial profile) at the time, instead of the complete nine attributes (full profile) all at once.The purpose for this was to reduce possible participants’ cognitive burden and response fatigue.
