The Index of the Company Stakeholder's Welfare is a regression model coefficient between shareholder & debt
holder - welfare as the dependent variable and the stakeholders besides those two parties welfare as the independent
variables. The optimum of the index is the optimum of the company’s attention to stakeholder’s interest fulfilment.
Whatever the indicator is, we need to propose a valuation model of a company in term of all stakeholders interest,
not only shareholders. Some things that needed to be considered for the 3 model proposed are the differences between
labour intensive company and capital intensive company, equipment intensive company, and a company that relies on
creative thinking and information technology, including minimum salary and wages rate.
