Summary by James R. Martin, Ph.D., CMA
Professor Emeritus, University of South Florida
One of the main reasons given for the accounting Ph.D. shortage is that the opportunity cost of pursuing a Ph.D. is too high for individuals who are already working in public accounting. The purpose of this paper is to show that obtaining a Ph.D. in accounting can provide a financial return for the recipient over his or her lifetime adequate enough to justify giving up a career in public accounting. This study addresses the issue from a monetary perspective ignoring other reasons to pursue or not pursue a Ph.D. in accounting (e.g., flexible schedule, high level of autonomy, higher quality lifestyle, or lack of Ph.D. student support, or lack of interest in doing basic research, etc.). The authors conduct simulations to calculate the return on investment for a Ph.D. degree in accounting for hypothetical individuals who switch from public accounting careers after 3, 5, and 7 years. The simulations show a positive return on investment ranging from 5 percent to over 22 percent depending on the number of years in public accounting, number of years in a Ph.D. program, and specific career path.
The hypothetical individuals used in the simulations have three to seven years of experience in public accounting and are assumed to be individuals who would not eventually become partner since the partner track is not typical (Note: According to the AICPA only 2 percent of public accountants become partners). In addition to the experience variable, the simulations are based on a time in the Ph.D. program variable of four, five, and six years. After receiving their Ph.D.s each individual obtains a tenure-track position at a research-focused university such as the schools in the Big 12 (Beyer places these schools in Tier 3), and follows a forty-year career path in accounting. There are also four career scenarios based on whether the individual stays at a single university, or moves to receive a market salary adjustment, becomes a full professor, or remains at the associate professor rank throughout their career. The public accounting salaries used in the simulations are based on Robert Half's International Salary Guide. Academic salaries are based on the AACSB Salary Surveys.
The various equations used in the simulations are provided along with several tables showing the ROI at different points in an individual's career. The graphic illustration below provides an overall view of the career return on investment averaged across all scenarios.
A best case scenario is where an individual who leaves public accounting after three years, receives a Ph.D. after four years in a doctoral program, becomes an associate professor in the seventh year, and a full professor in the fourteenth year (Scenario I). Using the assumptions in their model, this individual would earn a career return on the Ph.D. investment of 22.78 percent. A worse case scenario is where an individual who leaves public accounting after seven years, receives a Ph.D. after six years in the doctoral program, moves to receive a market adjustment in year four, becomes an associate professor in the seventh year, and never makes full professor (Scenario IV). This individual would earn a career return on the Ph.D. investment of 5.21 percent.
The results of these simulations have a number of implications. First, the argument that the opportunity cost of pursuing a Ph.D. is too high for individuals who are already working in public accounting does not appear to be valid. Potential Ph.D. students are either unaware of the financial advantages of receiving a Ph.D. or do not pursue an academic career for some other reason. Other reasons for the lack of interest in pursuing a Ph.D. include the view that adequate support is not available for Ph.D. students, Ph.D. programs require too much time, and the type of research required to obtain a Ph.D. and to eventually obtain tenure and promotion in research-oriented universities is not appealing. Ph.D. program administrators need to make potential candidates aware of these findings and address the issue of adequate support for Ph.D. students.
The authors developed a web site with a downloadable ROI calculator so that potential Ph.D. candidates can make their own calculations. To download an Excel spreadsheet to make your own ROI calculations using different scenarios see the authors' web site at http://www.mgt.unm.edu/roi
