Economists work in a broad range of policy areas and address questions such as the following: What is the best way to fight environmental pollution? What is the appropriate role of government in economy? What rules should govern trade among nations? What is the appropriate economic policy for developing and increasing immigration? What are the effects of tax cuts, budget deficits, and welfare policies on the overall economy? Economists may address fundamental policy issues such as these and others within narrower fields such as health care, agriculture, education, crime, politics, urban and regional development, law, history, energy, and the environment, among many others. The B.A. in Economics is structured to provide the opportunity for students to earn minor degrees in many of these specialized fields.
