We present a collaboration with the OCP Group, one of the world's largest producers of phosphate, in support of a green initiative to reduce OCP's carbon emissions significantly. We study the problem of decarbonizing OCP’s electricity supply by installing a mixture of solar panels and batteries to minimize its investment cost plus the cost of satisfying its remaining demand via the Moroccan national grid. This forms the basis for a one billion USD investment in renewable energy generation.

Problem: Evaluating an ED delay announcement system in Hong Kong's healthcare. Methodology: Studying 1.3M patient visits, we estimate patient sensitivity to announced waiting times (WT) and factors influencing it. Results show potential improvements in reducing WT and patients leaving without being seen.

Online agri-platforms, like Karnataka's United Market Platform (UMP), aim to improve smallholder farmers' welfare. This study designs a two-stage auction on the UMP, increasing farmers' revenue with over $6 million in commodity trades. Results show a 3.6% price increase (55%-94% profit gain), benefiting 10,000+ farmers. Lessons highlight innovative price discovery in resource-constrained environments, emphasizing operational and behavioral factors for success.
