I am a visiting scholar at Cambridge University, UK, and principal investigator for the project “Schistosomiasis, Agriculture and Migration in Africa: a joint Economic and Ecological Approach” funded by the Swiss Network of International Studies. My current research studies the economic impact of endemic diseases, with a focus on Sub-Saharan Africa. Additionally, I work in mathematical economics, especially on applications of stochastic analysis and control to development, health and environmental economics. I am a classical pianist.

We extend the celebrated Rothschild and Stiglitz (1970) definition of Mean-Preserving Spreads to a dynamic framework. We adapt the original integral conditions to transition probability densities, and give sufficient conditions for their satisfaction. We then focus on a class of nonlinear scalar diffusion processes, the super-diffusive ballistic process, and prove that it satisfies the integral conditions. We further prove that this class is unique among Brownian bridges. This class of processes can be generated by a random superposition of linear Markov processes with constant drifts. This exceptionally simple representation enables us to systematically revisit, by means of the properties of dynamic mean-preserving spreads, workhorse economic models originally based on White Gaussian Noise. A selection of four examples is presented and explicitly solved.
