The PhD Program in Business Administration may be available from certain graduate business schools in the USA. These advanced degrees may be offered by the graduate business school as a whole or through individual departments (such as Economics).
Typically, a PhD in Business will take between 4 and 6 years to complete, depending on the student. The first 2 years are usually devoted to coursework, including small seminars. Students collaborate closely with faculty in their department/ area of specialization to determine the specific program of study based on their personal background, goals and interests. Students pursue expertise in an area of special interest via the coursework plus independent study and a comprehensive exam in this area (usually during the second or third year). PhD programs in business focus heavily on independent study and research. Therefore, the final requirement is the proposal, writing and presentation of a dissertation.
A PhD in business may be available in a number of different specialization areas, such as accounting, finance, marketing, operations management, decision sciences, international business and more. These are highly competitive programs, and the acceptance rate can be as low as 10%. A PhD in Business is designed for students seeking academic research and teaching careers or other careers where advanced research and analytical skills are needed.
