“…Commonly used models to account for heterogeneity in preferences include the random parameter logit (RPL) [17,18] and the latent class model [19,20]. Both the RPL and LCM incorporate heterogeneity in attributes, the systematic component of utility, but are based on different assumptions about the heterogeneity distribution.…”

“…The option for maintaining the status quo reflects a shopping choice for consumers who may prefer not to consume precooked beans. The alternative specific constant (ASC) was chosen to equal to 1 when the respondents selected options A or B and 0 for the option C [20]. If the ASC is negative and significant, then the propensity of the consumer to choose the status quo is high and vice versa.…”

Background: This study investigated consumer demand heterogeneity and valuation of a processed bean product-"precooked beans" with substantially reduced cooking time. Common bean is the most important source of protein for low-and middle-income households in Uganda. Its consumption is, however, constrained by long cooking time, high cooking energy and water requirements. As consumption dynamics change due to a rapid expansion of urban populations, rising incomes and high costs of energy, demand for fast-cooking processed foods is rising. An affordable, on-the-shelf bean product that requires less time, fuel and water to cook is thus inevitable.Methods: A choice experiment was used to elicit consumer choices and willingness to pay for precooked beans. Data used were collected from 558 households from urban, peri-urban and rural parts of central Uganda and analyzed using a latent class model which is suitable when consumer preferences for product attributes are heterogeneous. Results:Study results revealed three homogeneous consumer segments with one accounting for 44.3% comprising precooked bean enthusiasts. Consumers derive high utility from a processed bean product with improved nutrition quality, reduced cooking time and hence save water and fuel. The demand for the processed bean is driven by cost saving and preference for convenience, which are reflected in willingness to pay a premium to consume it. Heterogeneity in attribute demand is explained by sex and education of the respondents, volumes of beans consumed, location and sufficiency in own bean supply. Conclusions:Our findings suggest that exploring avenues for nutritionally enhancing while optimizing processing protocols to make precooked beans affordable will increase consumer demand. These results have implications for market targeting, product design and pricing of precooked beans.

“…Variety choice is driven by farmers' demand for a number of variety traits (Smale et al, 2001). The paper follows arguments from previous literature that farmers choose varieties based on the bundles of observable characteristics that each variety embodies and produces (Smale et al, 1998;Edmeades and Smale, 2006;Wale and Yalew, 2007;Kikulwe et al, 2011). In this study, we assume that an individual farmer faces a choice among alternative hybrid banana varieties.…”

This paper analyses the effect of farmer characteristics, variety attributes and agro-ecological conditions on farmers' banana variety choice decisions in Uganda. A Multinomial Logit (MNL) model was used to estimate the determinants of variety choice. The results show that M9 was the most preferred hybrid variety, followed by M2 and M14. However, many of the respondents (39.4%) chose Mbwazirume, a local variety, as their most preferred variety. Good taste, large bunch size, soft food and good flavour were the most desirable attributes, while longer maturity period was a notable undesirable attribute. Results from the MNL analysis suggest that small land size, taste and regional location were negatively associated with variety choice, while perceptions that hybrid bananas could reduce food insecurity and tolerance to pests and diseases were positively associated with probabilities of variety choice. Probabilities of choosing hybrids for food security increase in favour of M2 (by 6.13%) and M9 (27.60%), and decrease by 23.05% for M2, 6.89% for M14 and 9.36% for M9 due to taste relative to Mbwazirume. Farmers' involvement in varietal improvement and development programmes is vital for meeting their preferences. Future breeding efforts should consider attributes such as bunch size, good taste, soft food and agronomic characteristics. Farmers with large land sizes should be targeted for on-farm promotional activities to increase the potential adoption and impact of the hybrids. After the hybrids are popularized and used by farmers, there will be a need for an impact study to evaluate their acceptability in terms of household food security and income.

“…We differentiate between consumer groups using the following parameters: differences by income group; willingnessto-pay (WTP) for GM bananas; spatial location; and whether or not they, as consumers of bananas, are also banana producers. This allowed us to investigate whether or not wealthier consumers may trust GM food labels, as those consumers are often opposed to GMOs, as suggested by Paarlberg (2008) and confirmed for Uganda by Kikulwe et al (2011a).…”

Food labelling is costly. Food labelling is often demanded with the introduction of new food products such as genetically modified (GM) food. If consumers do not have trust in the label, scarce resources are wasted. This paper investigates factors affecting the trust in food labels among Ugandan consumers. The results suggest that older, less-educated individuals of smaller household sizes and with trust in government institutions have more trust in food labels. Other factors were also found to be important. The government has to consider those differences in consumer trust when designing a GM labelling policy.
