Through the application of the Macro Multiplier (MM) approach on an Input-Output matrix for US economy in year 2005, the paper identifies the 'convenient' structure of a policy control on final demand, oriented to a particular policy objective. The approach quantifies a set of aggregated scale effects, called MM, and the associated structures of both policy and objective variables. In this way the policy maker can both get a complete picture of the patterns of the objective that can be attained and determine a 'convenient' structure of the policy variable that compels the model towards those patterns.

This study made an effort to build the Social Accounting Matrix for the Nigerian economy, which describes the income circular flow through the integration of the production with the income flows, including both the generation and the distribution of value added and the creation of final demand. Such database allows developing an extended input-output model and a Macro Multipliers analysis based on the technique of singular value decomposition. First, the analysis identifies the key sectors amongst the agricultural sectors that have significant interactions with the other commodities of the economy. Furthermore, the Macro Multipliers analysis is conducted in order to identify the interactions between policy objective (total output) and policy control (final demand) at a multi-sectoral level.
