This paper aims to take advantage of the Keynesian approach in framing the relationship between the size of employment and capital accumulation. In addition, the study will try drafting a new approach for calculating the opportunity cost based on defining the job opportunity through the size of investments needed for its creation. This study is based on the assumption that there is a correlation between the increasing employment rates and the size of investments in the economy. In order to test this hypothesis a time cross-sectional data analysis method has been used (Pooled Data) as well as PWT (Penn World Table). The findings showed that there is a strong positive relationship between the net capital formation at constant prices and created jobs. It was also showed that the efficiency of employment is very low in the countries studied but not exceeding 1 per thousand. Hence, it is recommended that economic policy-makers in those researched countries need to focus on improving the investment environment -locally and regionally- in order to mobilize more investment.

The portfolio analysis with its planning matrices as the most useful tools is still widely used in corporate strategy's formulation. A stream of literature indicates precisely when a Strategic Business Unit (SBU) should be eliminated, yet does not show how to do so. This paper aims to develop a theory-based model for SBU elimination. A framework was developed through an extensive literature review of portfolio analysis in which each standardized matrix structure, assumptions, strengths-weaknesses and strategic applications were thoroughly outlined. This framework includes four dimensions: cost, revenue, structure of capital and strategic dimension. This proposed framework would be considered as a strategic tool for both professionals and practitioners when time comes to take a decision about SBU elimination.Having a business portfolio may prove to be a dreadful experience if not handled properly. Thus, this study will surely help the business community in the manifestation of structural business planning, analysis and management for the ultimate business success.
