Dear researcher, many organizations (OECD, UN, UNESCO, ILO) and many studies on this subject are investigating the concept of "Human Capital", which is a sub-dimension of "Intellectual Capital". Human Capital applications will probably answer your question. You can review Thomas A. Stewart's book.

Certainly, Mr. Omer, thank you for splitting your time. Intellectual capital studies quiet popular here to be carried forward, surely will take into account. Thank you.

When doing research in any field it is better to start with systematic literature reviews, it will give you a deep insight to the actual state of knowledge in the field, provide you with many research gaps and the good thing is that it includes -most of the time- future research agendas: different theoretical frameworks to use, needed research methodologies and contexts.

As for HMR and employee well-being, what is noticed is that mental health has become a very important and it is rising many growing concerns, especially after the Covid-19 pandemic; so, what is most discussed in HMR is psychological well-being (or psychological Wellness): employee resilience, social anxiety, psychological safety, burnout ... related to

job satisfaction, performance, turnover, organizational dehumanization, sabotage behaviors, work environment, workload, and work-life balance….

Ps: Human capital theory as suggested by sir Ömer Özbey could be a good theoretical framework to such studies.

All the best

Indeed, mental health issues in HRM became a growing studies. It was a great sharing ideas, definitely will take into account.

Thank you.
