Welcome to the Division of Economics and Decision Sciences

Perhaps the most important resource we have today is data. Data helps us make sense of the world around us and make decisions that impact the future. At the USD Beacom School of Business, our professors understand the importance of data and are experts at explaining its uses in the business world. As a student in the Division of Economics and Decision Sciences, you'll graduate having had hands-on experience in collecting, interpreting and applying data to real-world problems. You'll be ready for a career in a variety of fields, including accounting, the insurance industry, supply-chain management and more.

Success story Pooja Modawel smiling.
I really like how approachable the Economics and Operational Analytics faculty is and how they are willing to help me out with my concerns. The career planing facility offered by Beacom assisted me with updating and revising my resume. They even prepared me for job interviews that helped me get an internship with Amazon.
