However, antibiotics become obsolete the more they are used as selection pressure promotes the development of resistant bacteria. The World Health Organization has proclaimed antibiotic resistance as a major global threat to public health. Today, 700,000 deaths per year are due to untreatable infections. To win the battle against antibiotic resistance, new policies affecting the supply and demand of existing and new drugs must be designed. In this project, we pursue new research to identify and evaluate feasible and effective demand-side policy interventions targeting the relevant decision makers: physicians and patients. ABRSEIST makes use of a broad econometric toolset to identify mechanisms linking antibiotic resistance and consumption exploiting a unique combination of physician-patient-level antibiotic resistance, treatment, and socio-economic data. Further, it aims to shed light on general practitioners\u2019 acquisition and use of information under uncertainty about resistance in prescription choice, allowing counterfactual analysis of information-improving policies such as the provision of machine learning predictions in clinical practice and mandatory diagnostic testing. Using machine learning methods, theory-driven structural econometric analysis, and randomization in the field we work to provide rigorous evidence on effective intervention designs. This research will improve our understanding of how prescribing, resistance, and the effect of antibiotic use on resistance, are distributed in the general population which has important implications for the design of targeted interventions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"research-output\">Research Output<\/h3>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"https:\/\/www.hannesullrich.com\/files\/humanskillmachineprediction.pdf\" target=\"_blank\" rel=\"noopener\">Machine predictions and human decisions with variation in payoffs and skill: the case of antibiotic prescribing<\/a> (Michael A.
