Applied Economics In the MIT Sloan Applied Economics Group, we use economic theory and econometrics to address the practical challenges facing humanity. Our research spans a wide variety of fields, theoretical and empirical, and integrates a broad spectrum of tools. Our focus: high quality research with real-world implications. We study organizations, health economics, macroeconomics, pricing, markets and industrial organization, development economics, and energy and environmental economics. Like our peers across the Institute, we are always pushing the research frontier, collaborating widely with other academics and policy makers in the United States and around the globe.
