Is it possible to have both an MBA degree and a Ph.D.? If so, which one would be more useful after obtaining the other one?

Pursuing both an MBA and a Ph.D. is achievable while individuals often prefer gaining a Ph.D. after their MBA experience in business-related fields including management and finance; your career prospects within academia or business research benefit most from a Ph.D. as it develops advanced research skills and deepens your expertise knowledge. Therefore, there are some points that need to be considered

• Traditional business roles in management or consulting benefit most from an MBA education whereas academic professor or research positions together with specialist consulting roles featuring an advanced level of domain knowledge require a Ph.D. academic credential. 
• The research component of a Ph.D. deepens your focus on business subjects which leads creation of new industry theories and market insights. 
• Students must commit additional time and put in extra effort to complete a Ph.D. after their MBA program than they would need for an MBA by itself.
