Economics is a social science that covers a broad subject matter in seeking to understand the social world. Economics studies the behavior of social systems—such as markets, corporations, legislatures, and families—as the outcome of interactions through institutions between goal-directed individuals. Doing economic research involves asking questions about the social world and addressing those questions with data and models, employing mathematical and statistical tools whenever possible to aid the analysis.
The Ph.D. program in the Department of Economics is addressed to students of high promise who wish to prepare themselves for careers in teaching and research in academia or for responsible positions in government, research organizations, or business enterprises. Students in the department are free to pursue research interests with scholars throughout the University. Faculty of Harvard Law School, Harvard Kennedy School, and Harvard Business School, for example, are available to students for consultation, instruction, and research guidance.
