Experimental auctions, collective induction and choice shift: willingness-to-pay for rice quality in Senegal

We propose a collective induction treatment as an aggregator of information and preferences, which enables testing whether consumer preferences for food quality elicited through experimental auctions are robust to aggregation. We develop a two-stage estimation method based on social judgement scheme theory to identify the determinants of social influence in collective induction. Our method is tested in a market experiment aiming to assess consumers willingness-to-pay for rice quality in Senegal. No significant choice shift was observed after collective induction, which suggests that consumer preferences for rice quality are robust to aggregation. Almost three quarters of social influence captured by the model and the variables was explained by social status, market expertise and information

Diabetic foot care and prevention in Senegal: adding an extra dimension to the Step-by-Step model

Every 30 seconds, a lower limb is amputated as a result of diabetes; of all the amputations in the world, about 70% are suffered by people with diabetes – foot ulceration being a key factor in developing regions. Yet these amputations can be prevented. As well as medical factors, numerous social and socio-environmental issues affect the development of diabetic foot problems. This report focuses on Africa-specific factors. Although in Africa neuropathy is a major contributing factor, it is not the only one: even a simple injury that becomes infected can be a precursor to amputation. The authors reflect on some of the factors affecting diabetes care in Senegal, and make some suggestions for improvements in the prevention and management of the diabetic foot

What is the value of rice fragrance? Consumer evidence from Senegal

Urban demand for fragrant rice is increasing rapidly in Senegal, but little is known about the value of rice fragrance and the drivers of its demand. We conducted experimental auctions in Dakar to elicit urban consumers’ willingness to upgrade from non-fragrant to fragrant rice and their willingness to pay for domestic versus imported fragrant rice, and assessed the drivers of demand for rice fragrance through a double-hurdle model. The average value of rice fragrance is estimated to be around US$ 0.12 kg-1, as suggested by the 20% price premiums consumers are willing to pay on top of the price of non-fragrant rice. These price premiums further increase to 35% for consumers who express positive buying intentions towards domestic fragrant rice. The value of rice fragrance is found to be driven by factors such as ethnicity, household size, and awareness of fragrance and local fragrant rice
