## ABSTRACT

This chapter will present input-output preliminaries to the multi sectoral linear programming models discussed in the subsequent chapters. Leaving its rigorous mathematical formulation to the next chapter, we shall in the present chapter limit our input-output analysis to the fundamental assumptions, variables, and relations involved. Specifically this chapter will deal with: (a) the structure of input-output relations, and (b) the endogenous net capitalformation sector. The first of these section will be found to involve a static Leontief input-output model, while the second section will be found to indicate the possibility of integrating the Leontief approach and the post-Keynesian growth theory involving explicit linear relations and implicit optimands.
