Researchers in HR prefer to use perceived performance for their research study instead of actual financial performance.

Research paper [Wall, T. D., Michie, J., Patterson, M., Wood, S. J., Maura, S., Clegg, C. W., & West, M. (2004). On the validity of subjective measures of company performance. Personnel Psychology, 57, 95–118.] indicated subjective and objective measures of company performance were positively associated. Hence it could be an assumption that perceived performance represents actual performance. Some researchers indicate the use of perceived performance as a research limitation  Could you please elaborate/discuss the reasons to use perceived performance in HR or advantages/ disadvantages of perceived performance? Thank you.
