We use a series of credit and insurance simulation games to test the role of access to credit and insurance on magnitude and timing of farm technology uptake with small-scale farmers in South Africa. Using Cumulative Prospect Theory, we assess how insurance impacts technology uptake given risk preferences. Our findings suggest that risk aversion is linked to lower uptake of the insured technology. while loss averse farmers are more likely to adopt technology bundled with insurance. Higher weighting of small probability events leads to later uptake of the uninsured technology option.
Even though antiretroviral treatment is becoming more efficient and available, new HIV infections still occur. This is particularly the case in sub-Saharan Africa. Sexual transmission of HIV is still the main mode of transmission in sub-Saharan Africa, and multiple sex partners have been shown to be crucial for the spread of the epidemic. It is therefore problematic that sexual risk-taking, in terms of multiple sex partners, persists in spite of HIV awareness and knowledge.
This study measures the link between expected health and contextual health uncertainty on sexual behaviours associated with the risk of HIV infection. We extend similar studies on the subject by focusing on contextual factors as a way of explaining individual sexual behaviour in low and high HIV infection areas across sub-Saharan Africa. Overall, we find expected health and contextual health uncertainty to have significant effects on sexual risk taking. These results point to the fact that context is equally important than the widely held view that individual level characteristics (e.g.
